Present agriculture production scenario in India
(in mt.)

6. In times to come, Indian agriculture will meet the
requirements of food security and rapidly diversify itself.
Indian agriculture is already increasingly demand driven.
This will accelerate in the future.
It has been argued on various occasions that agricultural
diversification in India is basically driven by domestic
demand.
Population and Income Growth will give us the base for
demand. Decadal Growth of cereal demand is 13 per
cent.
On the other hand growth of demand of fruits and
vegetables, eggs, chicken and milk is much higher.
The FAO note that according to popular statistics India is
less urbanized, but they point out that:
“On the other hand, what constitutes “rural” is in fact
somewhat subjective and what is considered urban or
rural varies considerably among countries.

RCT.”
WHAT IS RCT
 A resource is any natural or artificial substance or
energy which can be used for the benefits of mankind.
 Natural resources are those which exist in the
environment naturally, that is, they are not created by
humans. They are soil, water, sunlight, the wind, plants,
coal etc.
 To support life by supporting ecological balance
 To ensure that the future generations will be able to
access the resources.
 To preserve the biodiversity.
 To make sure human race survives.

Conservation Agriculture-CA
CA is based on integrated management of soil, water and agricultural resources in
order to reach the objective of economically, ecologically, and socially sustainable
agriculture production. It relies on three major principle.
-Jat et. al
CA Vs RCTs

11. “ALL THE CA TECHNOLOGIES IS CALLED AS RCTs, BUT ALL THE RCTs MAY NOT BE CA.”

RCTs may not be follow all the three principles of CA that is clarified in case of

13. Laser Land Leveling
 It alter fields having
a constant slope of 0 –
0.2%.
 Using laser equipped drag
bucket which allows the
land surface smoothening
within ±2 mm from its
average elevation.
 Helping in saving irrigation
water up to 20 - 30%.
Jat et al., 2011
Various RCTs which can be apply
in land management

14. Zero Tillage Technology
 It is an extreme from of minimum tillage.
 Primary tillage is completely avoided and secondary tillage is restricted done only in
the row zone.
 It is more related to with less than 30% of soil disturbance.
 In RWCS by this technology saves 70-80% time as well as increases 15-20 % wheat
yield.
 Cut down the dose of diesel around 35l-45l per hectare of land.
Dr. Mahesh et. al.

15.  It is a machine that can sow
seeds and fertilizer in a single
operation at the right place
without any kind of tilling and
soil disturbance.
 This machine can work
easily with every type of crop
residue with a load of 10-12
tones without any problem.
 It has 9 tones which means
that it can seed nine rows in
one operation.
 It needs a minimum of 45HP
double clutch tractor and its
weight around 750kg.
 This machine can cover 10-
15 hectares.
(Chaudhary et. al.,2016)
Happy Seeder Technology

16. Bed Planting Technique
 It is the method
where cultivation of crops is done
on raised beds.
 It has the potential to conserve
significant quantities of water
up to 30-50%.
 Fertilization practices are also
easily performed by trafficking
in the furrow bottoms.
 Reduced seed rates, conserved
rainwater, easy facilitated
mechanical weed control,
minimized lodging in crops.
(Gupta et. al.)

17. RCTs for nutrient management Site Specific Nutrient
Management
SSNM provides an approach for
‘feeding’ rice with nutrients as
needed Make optimal use of
existing nutrients, such as from
soil, residues, and manures.
Feeding
Crop needs!
1-Establish a yield target – the crop’s
total needs.
2- Effectively use existing nutrients.
3- Fill deficit between total needs
and indigenous supply. -
(Walker et.al)

18. It is the Tools for the Need and Assessment
of Nitrogen in Paddy ,maize, sugarcane,
potato and vegetable crops.
It is based on the leaf color.
The intensity of the leaf color is indicative
of the amount of nitrogen.
(Nachimuthu et.al.,2007)
Leaf Color Chart

19. 
Green Seeker
 It is an integrated optical sensing , variable rate
application & mapping system that measures crop's
nitrogen requirements.
 Yield potential for a crop is identified using a
vegetative index known as NDVI (normalized
difference vegetation index) and an environmental
factor.
 The technology was developed at Oklahoma State
University, USA and licensed to N Tech Industries in
2001 (http://www.ntechindustries.com).
 It offers a more efficient and precise way to manage
crop input i.e. nitrogen.
 Nitrogen (N) recommendation based on yield
potential and the Response Index (RI).
 The Green Seeker estimates the right amount of N at
the critical stages of crop growth.

20. NNANOFERTILIZERS
Use of Nano fertilizers
Nano fertilizer refers to a product that delivers nutrients to crops in one of three ways:
1. The nutrient can be encapsulated inside Nano-materials such as nanotubes or Nano
porous materials
2. coated with a thin protective polymer film
3. delivered as particles or emulsions of nanoscale dimensions.
4. Slow, targeted, efficient release becomes possible.
5. In some cases, the nano particles itself can be used.
Examples-
Neem coated fertilizer
Sulphur coated fertilizer
Polymer coated fertilizer

21. Various RCTs used in crop production.
SYSTEM OF RICE INTENSIFICATION
 Planting young (8-10 days) old seedlings, planting a single seedlings per hills.
 Wider space square planting 20cm to 20 cm.
 Save water 15-30% and WUE about 5.7-5.8 kg/ha-mm.
(Das et. al.)

22. Direct-seeded rice.
WR for raising seedling for one ha land is
about 40–60ha-mm.
Water needed for puddling and transplanting
operation in case of TPR require 200–300
ha-mm of water/ha.
(Sharma,2000)
Total water saving in DSR is 35-40%
compared with puddled transplanted rice.
(Saharawatetal.,2010)
Crop diversification
Seed priming (Farooq et al., 2006)
Use of osmo-protectants (Farooq et al.,
2007)
Application of silicon(Ma, 2004)

23. Modified Practices
 Lower seed rate.
 Seed treatment.
 Sowing of seeds at
 Proper spacing.
 Control of water in the
 Crop field.
 Weeding / hoeing.
WHAT IS SWI ?
Outputs / Results
 Higher ratio of tillers to
 Mother seedlings.
 Increased number of
 Effective tillers / hill.
 Enhanced panicle length &
 Bolder grains.
 Enhanced yield.
SWI can enhance grain yield as much as 25 per cent
sustaining the ever burgeoning population.
Minimum chemical use sustains soil ecology.
Only 25kg/ha seed needed.
(Anil Kumar et.al)
System of wheat intensification

24. Furrow irrigated raised
beds(FIRB)
In this method of sowing FIRBs are
made and keep 15cm distance rows
and 55cm width and 30cm wide
furrow between two beds. It save
about 20 –30 % water saving.
(Tanwar et al., 2014)
Trash mulching
On an average 20million litters of
water/ha Covering of soil surface
with trash mulch, and is done by
uniform(10cmthick)spreading of
trash in inter row space.
It save water 3O-40%.
(Srivastava et. al.)
RCTs for irrigation

25. The soil dug up from the pit is kept in the periphery of the ring in 30 cm space
left in between the two pits.
Two budded sets placed like spokes in a cycle wheel more than 40% surface area
remains dry.
It save 30-40% water
(Singh et al.,1984)
Ring pit method of planting

26. It is sometimes called trickle irrigation
and involves dripping water onto the
soil at very low rates (2-20 litres/hour)
from a system of small diameter
plastic pipes fitted with outlets
called emitters or drippers.
Water is applied close to plants so
that only part of the soil in which the
roots grow is wetted (Figure 60),
unlike surface and sprinkler irrigation,
which involves wetting the whole soil
profile.
Drip irrigation is most suitable for row
crops.
Drip irrigation is adaptable to any
farmable slope.
It has 85-90% WUE.
(Singh et. al)

32. CONCLUSION
• RWCS occupies 13.5 Mha land on the IGP’s of SA including India.
• Green revolution not only degraded soil but also overexploited
groundwater.
• RCT’s which form the basis for CA has the only solution to save soil,
water and other natural resources.
• Zero tillage and happy seeder sowing technology in wheat, maize
and soybean not only save money and give similar or higher yields in
various crops but also reduce the weed problem and environmental
pollution.
• Laser land leveling, crop diversification, conservation agriculture, most
suitable irrigation and crop establishment method with appropriate
irrigation scheduling are the possible agronomic options for halting the
ground water decline in IGPs
