Tillage is the mechanical manipulation of soil with tools and implements for obtaining conditions ideal for seed germination, seedling establishment and growth of crops.
Training is an important operation in grapes.
It helps to maintain the stature and spread of the vine and facilitates operations like pruning, intercultivation, spraying and harvesting.
Many training systems are in vogue in India, but the most popular are Bower, Telephone and Kniffin systems.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .

Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Irrigation and fertilizer application methods in horticultural crops by Dr. Kore
1. Irrigation
It is defined as the artificial application of water to the plants in the event of
shortage of natural rains in order to obtain rapid growth and increased yield.
It is an essential item in the cultivation of crops.
Success in gardening depends on how efficiently irrigation is provided to gardens
because it is governed by many factors such as frequency, duration, intensity,
source and method of supply.
Factors affecting the supply of irrigation water to plants
Topography and soil characteristics.
Kind of plant (root depth, water absorption capacity, growth habit, etc.).
Weather condition.
2. I. Surface irrigation
a. Flooding
b. Basin type
c. Furrow type
d. Ring type
II. Sub-surface irrigation
a. Trench method
b. Through underground pipelines
c. Perforated pipelines.
III. Overhead or aerial irrigation
a. Sprinkler
b. Revolving nozzles
IV. Drip or trickle irrigation
Methods of Irrigations
3. I. Surface Irrigation
When the land is flat, letting in water from one end floods the entire area.
This system is commonly practiced in canal or tank bed areas.
It is the easiest method and permits the use of bullock drawn implements in the
orchards.
But in this there is wastage of water and leads to soil erosion also.
It encourages growth of weeds and spread of diseases like gummosis in citrus
and collar rot in papaya.
a. Flooding
Uncontrolled flooding
Controlled flooding
4. b. Basin system
In this system, circular basins are provided around the trunk of the tree.
The basins are inter-connected in series and are fed through the main channel
running perpendicular to the tree rows.
When compared to flooding, this system minimizes the loss of water.
In this system of irrigation, the water close to trunk may bring about certain
diseases like gummosis and nutrients are likely to be carried over from one basin
to the other.
5. c. Furrow system
Entire land surface is not covered with irrigation water.
The furrows are opened in the entire orchard at 4” or less apart, depending upon the
age of the trees.
Water is let in these furrows from the main channels.
In orchards, two furrows on each side of the rows are generally made.
It is suited to such lands, which have a moderate slope to the extent of 1-2% if the
water is to run freely and reach the ends of the furrows.
Where the slope is sharp, the furrows are made to follow the contour more or less
closely.
This method has disadvantage of excess of water penetration at the head than at the
farther end, which may result in variation in vigour and growth of trees.
6. d. Ring system
This is an improvement over the basin system.
In this system, a ring is formed close and around the tree and water is let into the
basin.
This method is recommended for citrus trees thereby reducing the chances of collar
rot to which these trees are often susceptible.
The size of the ring will increase as the tree grows.
In this system, the spread of diseases like collar rot, etc., are prevented.
However, it involves more labour and capital and it does not permit uniform
distribution of water throughout the bed or basin as in the basin system of irrigation.
7. II. Sub-surface Irrigation
This system consists of conducting water in number of furrows or ditches
underground in perforated pipelines until sufficient water is taken into the soil so as
to retain the water table near the root zone.
In limited situation, this may be a very desirable system of irrigation.
In general, however, it must be used with great caution because of the danger of
water logging and salt accumulation.
If the sub-strata are so slowly permeable that practically no water moves through,
water added may stand in soil sufficiently for long time which results an injury to
the plant root due to poor aeration.
Where irrigation water or the sub-soil contains appreciable amount of salt, sub-soil
irrigation is usually not advisable.
Land must be carefully leveled for successful subsoil irrigation so that raising the
water table will wet all parts of the field equally.
8.
9. III. Over Head or Aerial Irrigation
In this system, water is applied in the form of spring,
somewhat resembling rainfall.
This is accomplished by pumping water from original
source into the main supply line from where it is
distributed to perforated pipes, which operate at low
pressure (80 to 120 lb/square inch) and supply the
water in a fairly uniform rectangular pattern.
They have a high rate of application, usually 1”/hour
or higher. Because of the high application rates, their
use is restricted to soils with high infiltration rates,
such as sandy or gravelly.
Revolving nozzle is also at times used, which
operated on either low or high pressure. Usually the
rate of application followed in the rate of 0.2” to
0.3”/hour.
10. Sprinkler Irrigation
May have definite economic advantages in developing new land that has never
been irrigated, particularly where the land is rough or the soil is too much
porous, shallow or highly erodable.
It is quite useful where only small streams are available, such as irrigation wells
of small capacity.
It is helpful in irrigating at the seedling stage when the furrowing is difficult and
flooding leads to crusting of soil.
Fertilizer materials may be evenly applied by this method.
This is usually done by drawing liquid fertilizer solutions slowly into the pipe.
It has several disadvantages like
o High initial cost
o Difficult to work in windy location
o Trouble from clogging of nozzle
o Interference in pollination process and
o Requirement of more labours while removing or resetting.
o In general, this system is best adopted for areas where ordinary surface
systems are inefficient.
11.
12. IV. Drip or Trickle System
This is the most recent system of irrigating the plants.
It is usually practice for high value crops, especially in green houses and
glass houses.
There will be an installation of pipelines with nozzles very close to the
soil.
The nozzle is fitted in such a way that water is dripped almost in the root-
zone of the plants.
Water is allowed to move in pipes under very low or no pressure and it
drop at regular interval.
This system of irrigation has advantages like no disturbance of the soil;
soil moisture is maintained, lesser leaching of nutrients from the soil.

18. 1. Nutrients cannot be fully utilized by plant roots as they move laterally over long
distances.
2. The weed growth is stimulated all over the field.
3. Nutrients are fixed in the soil as they come in contact with a large mass of soil.
A) Broadcasting
1. It refers to spreading fertilizers uniformly all over the field.
2. Suitable for crops with dense stand, the plant roots permeate the whole volume of the
soil, large doses of fertilizers are applied and insoluble phosphatic fertilizers such as
rock phosphate are used.
i) Broadcasting at sowing or planting (Basal application)
The main objectives of broadcasting the fertilizers at sowing time are to uniformly
distribute the fertilizer over the entire field and to mix it with soil.
ii) Top dressing
It is the broadcasting of fertilizers particularly nitrogenous fertilizers in closely sown
crops like paddy and wheat, with the objective of supplying nitrogen in readily available
form to growing plants.
Disadvantages of broadcasting
19.
20. B) Placement
1. It refers to the placement of fertilizers in soil at a specific place with or without
reference to the position of the seed.
2. Placement of fertilizers is normally recommended when the quantity of fertilizers to
apply is small, development of the root system is poor, soil have a low level of fertility
and to apply phosphatic and potassic fertilizer.
i) Plough sole placement
1. In this method, fertilizer is placed at the
bottom of the plough furrow in a
continuous band during the process of
ploughing.
2. Every band is covered as the next furrow is
turned.
3. This method is suitable for areas where
soil becomes quite dry upto few cm below
the soil surface and soils having a heavy
clay pan just below the plough sole layer.
21. It is the placement of ammoniacal nitrogenous
fertilizers in the reduction zone of soil particularly
in paddy fields, where ammoniacal nitrogen
remains available to the crop. This method ensures
better distribution of fertilizer in the root zone soil
and prevents loss of nutrients by run-off.
ii) Deep placement
22. iii) Localized placement
It refers to the application of fertilizers into the soil close to the seed or plant in order to
supply the nutrients in adequate amounts to the roots of growing plants. The common
methods to place fertilizers close to the seed or plant are as follows:
a) Drilling
In this method, the fertilizer is applied at the time of sowing by means of a seed-cum-
fertilizer drill. This places fertilizer and the seed in the same row but at different depths.
Although this method has been found suitable for the application of phosphatic and
potassic fertilizers in cereal crops, but sometimes germination of seeds and young
plants may get damaged due to higher concentration of soluble salts.
b) Side dressing
It refers to the spread of fertilizer in between the rows and around the plants. The
common methods of side-dressing are:
Placement of nitrogenous fertilizers by hand in between the rows of crops to apply
additional doses of nitrogen to the growing crops and
Placement of fertilizers around the trees like mango, apple, grapes, papaya etc.
24. If refers to the placement of fertilizer in bands.
C) Band placement
It is practiced for the application of fertilizers in
orchards. In this method, fertilizers are placed
close to the plant in bands on one or both sides
of the plant. The length and depth of the band
varies with the nature of the crop.
i) Hill placement
When the crops like sugarcane, potato, maize,
cereals etc., are sown close together in rows, the
fertilizer is applied in continuous bands on one
or both sides of the row, which is known as row
placement.
ii) Row placement
25. D) Pellet application
It refers to the placement of nitrogenous fertilizer in the form of pellets 2.5 to 5 cm deep
between the rows of the paddy crop.
The fertilizer is mixed with the soil in the ratio of 1:10 and made small pellets of
convenient size to deposit in the mud of paddy fields.
Advantages of placement of fertilizers
1. When the fertilizer is placed, there is minimum
contact between the soil and the fertilizer and
thus fixation of nutrients is greatly reduced.
2. The weeds all over the field cannot make use of
the fertilizers.
3. Residual response of fertilizers is usually higher.
4. Utilization of fertilizers by the plants is higher.
5. Loss of nitrogen by leaching is reduced.
6. Being immobile, phosphates are better utilized
when placed.
27. It refers to the application of solution of N, P2O5 and K2O in the ratio of 1:2:1 and
1:1:2 to young plants at the time of transplanting, particularly for vegetables.
Starter solution helps in rapid establishment and quick growth of seedlings.
a) Starter solutions
The disadvantages of starter solutions are
i. Extra labour is required
ii. The fixation of phosphate is higher.
b) Foliar application
1. It refers to the spraying of fertilizer solutions containing one or more nutrients on
the foliage of growing plants.
2. Several nutrient elements are readily absorbed by leaves when they are dissolved
in water and sprayed on them.
3. The concentration of the spray solution has to be controlled, otherwise serious
damage may result due to scorching of the leaves.
4. Foliar application is effective for the application of minor nutrients like iron,
copper, boron, zinc and manganese. Sometimes insecticides are also applied
along with fertilizers.
28. c) Application through irrigation water (Fertigation)
It refers to the application of water soluble fertilizers through irrigation water.
The nutrients are thus carried into the soil in solution.
Generally nitrogenous fertilizers are applied through irrigation water.
d) Injection into soil
Liquid fertilizers for injection into the soil may be of either pressure or non-pressure
types.
Non-pressure solutions may be applied either on the surface or in furrows without
appreciable loss of plant nutrients under most conditions.
Anhydrous ammonia must be placed in narrow furrows at a depth of 12-15 cm and
covered immediately to prevent loss of ammonia.
e) Aerial application
In areas where ground application is not practicable, the fertilizer solutions are applied
by aircraft particularly in hilly areas, in forest lands, in grass lands or in sugarcane fields
etc.
