This document discusses different methods of sowing seeds, including broadcasting, drilling, dibbling, planting, and transplanting. Broadcasting involves dispersing seeds over soil manually or automatically, requiring less time and expense but also less production. Drilling places seeds in rows, allowing for control of depth and spacing but requiring more resources. Dibbling divides fields into plots for plant-by-plant sowing, increasing yield and facilitating weeding. Planting uses vegetative parts like potatoes instead of seeds. Transplanting grows seedlings for 25 days before transplanting to fields, favoring environmental conditions and higher production.

Principles of weed management
This document outlines the principles of weed management, including prevention, eradication, control, and management. Prevention focuses on stopping weed infestation through measures like using weed-free crop seeds, avoiding contamination of manure pits, and preventing the movement of weeds. Eradication aims to completely remove all parts of a weed from an area and is justified for noxious weeds, while control reduces weed infestations without elimination. Weed management takes a systems approach to minimize weed invasion and give crops a competitive advantage over weeds.
Bench terracing
Bench terracing involves constructing level or sloped platforms across a hillside to reduce soil erosion and facilitate agriculture. It has been used for thousands of years around the world. Bench terracing is well-suited to steep slopes under 30% with stable soil. It can improve crop yields by slowing runoff, increasing infiltration, and allowing different crops on benches. However, bench terracing requires significant labor to construct and maintain properly to prevent failures. Examples of historic and current bench terracing can be seen around the world, from the Philippines to France, the Middle East, and Asia.
Methods of weed control
This document discusses various methods of weed control, including cultural, physical, chemical, and biological methods. Cultural methods involve practices like tillage, fertilizer application, irrigation, crop rotation, and mulching. Physical/mechanical methods include hand weeding, hoeing, digging, sickling, and mowing. The document describes various mechanical weed control tools. Herbicides are also discussed, outlining their benefits and limitations. Biological control uses living organisms like insects and pathogens to control specific weed species. No single method is effective for all situations, so often an integrated approach using multiple methods provides the best weed control.
Diffusion and adoption
Diffusion and adoption of important components of knowledge and adoption process which plays a significant role in dissemination and implementation of the technology
Crop rotation and its principle
Repeated cultivation of crops or crops and fallow in a certain sequence on the same land is called crop rotation.
Erosion control measures
This document discusses various erosion control measures for soil and water conservation. It describes agronomic measures like contour cropping, strip cropping, and mulching which control erosion by reducing rain drop impact and increasing infiltration. Mechanical measures like bunding and terracing are also discussed. Bunds are embankments constructed across slopes to slow water flow, while terraces convert steep slopes into level platforms separated by retaining walls to control runoff. Different types of bunding, terracing and their applications are explained in detail.
Soil and Water Conservation
This document discusses various agronomic measures for soil conservation. It defines contour cultivation as conducting agricultural activities like plowing and sowing across the slope of the land. This reduces soil and water loss by interrupting runoff. Choice of crops and cropping systems can also impact soil conservation, with close-growing crops providing better protection than row crops. Other agronomic measures discussed include strip cropping, cover crops, mulching, and applying manures/fertilizers. Mechanical measures to conserve soil include contour bunding, graded bunding, bench terracing, and vegetative barriers.
Antitranspirants and their effect on crop
This document discusses antitranspirants and their effects on crops. It defines antitranspirants as compounds that reduce water loss through transpiration without significantly impacting plant growth or photosynthesis. There are four types of antitranspirants: stomatal closing, filmforming, reflecting, and growth retardants. The document provides examples of how antitranspirants have been shown to improve wheat, maize, barley and soybean yields under drought conditions by reducing water loss from the plants. However, it also notes that antitranspirants can potentially reduce photosynthesis and increase leaf temperatures if used.

methods of sowing Of crops
There are several different sowing methods for planting seeds, each with advantages and disadvantages. The main methods discussed are broadcasting, drilling or line sowing, dibbling, transplanting, and putting seeds behind the plough. Broadcasting involves scattering seeds over a prepared field by hand, while drilling places seeds in rows using an implement. Dibbling positions seeds individually using a dibbler. Transplanting involves growing seedlings in a nursery and then transplanting them. Putting seeds behind the plough drops seeds into furrows made by a plough. Factors like the type of crop, soil moisture, and costs determine which sowing method is best.
Dry land agriculture
This document discusses dryland agriculture, which refers to growing crops entirely through rainfall. It can be divided into dry farming (<750mm rainfall), dryland farming (750-1150mm rainfall), and rainfed farming (>1150mm rainfall). Dry farming occurs in arid regions and has frequent crop failures due to low and variable rainfall. Dryland farming occurs in semi-arid regions and has less frequent crop failures. Rainfed farming occurs in humid regions and has rare crop failures. The document also discusses various irrigation techniques like surface, localized, and subsurface irrigation that help supplement rainfall for crop growth.
Propagation and Dissemination of weeds
Weeds can propagate and disperse through various means. They propagate sexually through seed production or asexually through vegetative structures like rhizomes, stolons, tubers, etc. Seeds and vegetative structures are then dispersed by different agents like wind, water, animals, man, and manure. This allows weeds to spread over long distances and colonize new habitats. Common dispersal mechanisms include seeds or fruits with feathers, pappus, wings, etc. that aid wind dispersal, barbs and hooks that catch on animal fur for transport, and mimicry of crop plants that results in accidental human dispersal during farming activities.
SOWING AND PLANTING EQUIPMENT
Sowing involves placing seeds in soil at a proper depth and spacing. Common sowing methods include broadcasting, dibbling, drilling, and transplanting. Seed drills are machines that open furrows, place seeds at a controlled depth and rate, and cover them. Planters are used for larger seeds and perform similar functions. Components include a hopper, metering device, furrow opener, and covering mechanism. Planters can be calibrated to achieve the desired seeding rate. Factors like plate speed, cell size, and seed uniformity impact accuracy. Specialized planters exist for crops like potatoes and sugarcane. Proper equipment selection and operation help ensure efficient sowing and establishment of crops.
Soil and moisture conservation techniques
This document discusses various soil and moisture conservation techniques, which are divided into agronomic and engineering measures. Agronomic measures include conservation tillage, deep tillage, contour farming, strip cropping, mulching, and growing cover crops. These are used where land slopes are less than 2%. Engineering measures include bunding, terracing, trenching, and subsoiling, which are constructed barriers used on slopes greater than 2% to retain runoff. Broad bed furrows are also discussed as a technique using beds and furrows to store moisture and drain excess water.
Mechanical practices of soil conservation
The mechanical soil conservation practices aim to reduce runoff velocity, retain water in soil, and prevent erosion. These include making basins to collect and retain rainwater, breaking hard clay pans to improve drainage, subsoiling to promote water absorption, contour terracing to retain water and check erosion, contour trenching with pits across slopes, terrace outlets to safely remove excess water, gully control, and stream bank protection. Terracing is an expensive but important method, especially on steep land, involving constructing leveled areas at right angles to slopes. Factors like slope length and steepness, soil type, and precipitation determine terracing feasibility.

Each method has advantages like control over spacing but also disadvantages like time/cost requirements. Overall, the document provides an overview of common sowing techniques used in agriculture.
Soil parent material.pptx
This document discusses soil fertility and productivity. It defines soil fertility as a soil's capacity to provide nutrients to plants in balanced amounts without toxic concentrations. Soil productivity refers to a soil's ability to produce crop yields using management. Soil fertility greatly influences productivity - a productive soil must be fertile, though a fertile soil may not be productive due to other factors like climate. The document outlines physical, chemical, and biological factors that impact soil fertility including nutrients, organic matter, microbes, pH, and cation exchange capacity. It distinguishes macronutrients and micronutrients needed by plants and how nutrients are lost from soils over time.
SOIL TEST AND SAMPLING METHODS.pptx
Soil is a mixture that contains minerals, organic matter, and living organisms. It provides a growth medium for plants and habitat for other organisms while modifying the atmosphere. Soil is composed of approximately 45% minerals, 25% water, 25% air, and 5% organic matter. It is formed through mechanical, chemical, and biological weathering of rocks by forces like wind, water, and microorganisms or tree roots. Proper soil testing and sampling is needed to understand the soil composition and determine what nutrients plants need to grow well.
METHODS OF FERTLIZERS APPLICATION.pptx
This document discusses various methods for applying fertilizers, including solid and liquid fertilizers. For solid fertilizers, the main methods discussed are broadcasting, placement techniques like band placement and pellet application. Broadcasting involves spreading fertilizer uniformly over a field while placement places fertilizer in bands or spots. Liquid fertilizer application methods include starter solutions, foliar application, fertigation through irrigation water, injecting into soil, and aerial application by aircraft. The document provides details on how each technique is performed and its advantages.

It provides details on each method, such as the common deficiency symptoms observed on plants for different nutrient deficiencies. Plant analysis methods include rapid tissue tests, total analysis, and identifying critical nutrient levels in plants. Biological tests include field tests, using indicator plants, and microbiological and laboratory/greenhouse tests. Soil testing is a chemical method that estimates the nutrient supplying power of soil and identifies nutrient deficiencies. Modern approaches discussed are soil test crop response and the diagnosis and recommendation integrated system.
Acid Soils.pptx
This document discusses various techniques for evaluating soil fertility, including nutrient deficiency symptoms on plants, plant analysis, biological tests, soil testing, and modern approaches. It provides details on key cycles of major nutrients nitrogen, phosphorus, and potassium in soil and plants. These include processes of nitrification, denitrification, nitrogen fixation, phosphorus transformations in aerobic and anaerobic soils, potassium availability and transformations in soil, as well as uptake and roles of secondary and micronutrients in plants.
METHODS OF IRRIGATION.pptx
This document discusses various methods of irrigation. It defines irrigation as the artificial application of water to land to assist in crop production. Surface irrigation methods distribute water over the soil surface by gravity, including uncontrolled flooding and controlled techniques like check basins, ring basins, border strips, and furrows. Sprinkler irrigation applies water as spray or rain from above. Subsurface irrigation involves applying water below the soil surface, including drip/trickle irrigation which saves 50-70% water by applying it slowly through emitters.
CLASSIFICATION OF HERBICIDES.pptx
This document classifies herbicides based on their method of application, mode of action, mobility, time of application, and molecular structure. It discusses how herbicides can be soil-applied or foliage-applied, selective or non-selective, contact or translocated, applied pre-plant, pre-emergence, or post-emergence. The document also covers organic and inorganic molecular structures of herbicides and different formulation types including emulsifiable concentrates, wettable powders, granules, and water soluble concentrates.
CLASSIFICATION OF FERTLIZERS 1 - Copy.pptx
This document discusses the classification of fertilizers and integrated plant nutrient management systems (IPNMS). It defines fertilizers as materials that supply essential plant nutrients and classifies them as straight, complex, or mixed based on the number of nutrients present. It also discusses nitrogenous, phosphatic, potassic, secondary and micronutrient fertilizers. The document then defines IPNMS as the combined use of inorganic, organic and biological resources to sustain crop yields while maintaining soil health. The main components of IPNMS discussed are the use of inorganic fertilizers, organic manures, biological sources, and maintaining soil physical properties and managing problematic soils.
Acid and calcareous Soils.pptx
This document discusses acid soils and calcareous soils. For acid soils, it defines them as soils with a pH below 6.0 due to the buildup of hydrogen and aluminum ions from leaching of bases. This causes physical, chemical, and biological problems for plant growth. Liming raises the pH and improves nutrient availability and soil health. Calcareous soils have a pH above 7.0 due to calcium carbonate. Fertilizer management is different as some nutrients like phosphorus are less available in high pH conditions. Applying acidifying fertilizers and amendments can help lower the pH.
Soil fertility and productivity.pptx
This document discusses soil fertility and productivity. It defines soil fertility as the capacity of soil to provide nutrients to plants in correct amounts without toxic concentrations. Soil productivity refers to the crop yield potential based on management. A productive soil must be fertile, but a fertile soil may not be productive due to other factors like climate and pests. The main factors influencing soil fertility and productivity are physical (texture, structure), chemical (nutrients, pH), and biological (organic matter, microbes). Macronutrients like nitrogen, phosphorus, and potassium and micronutrients are essential. Fertile soils contain sufficient amounts of all required nutrients.
Nutrients Consumption.pptx
This document discusses various plant nutrient cycles. It covers the absorption patterns of nitrogen, phosphorus, potassium, and secondary nutrients by plants. Nitrogen is absorbed as nitrates or ammonium and uptake is highest in young, actively growing plants. Phosphorus is absorbed as phosphates and is concentrated in reproductive tissues and seeds. Potassium uptake can exceed nitrogen uptake and luxury consumption can occur if potassium is plentiful in soils. The document also discusses micronutrient removal by crops, nutrient interactions both antagonistic and synergistic, and factors affecting nutrient use efficiency.

METHODS OF SOWING.pptx
- 1. METHODS OF SOWING TOPIC Assistant Professor Mr. B.S Cheema By
- 2. SOWING DEFINITION It can be defined as a process of planting seeds into the soil. After sowing, the seeds germinate inside the soil and then grow up to become a complete plant. METHODS OF SOWING 1) Broadcasting 2) Drilling 3) Dibbling 4) Planting 5) Transplanting
- 3. BROADCASTING Broadcast planting is the practice of dispersing seeds over the surface of the soil. The seeds are dispersed on the seedbeds either automatically or manually during this phase.
- 4. BROADCASTING Advantages Disadvantages 1. Less time is required 1. More number of seeds are required. 2. Less expensive 2. Overall production is less. 3. Tillage implements are not required. 3. Harvesting is difficult.
- 5. DRILLING Drilling of seeds are placed row lines in the soil. In weed crop distance of row to row is 22.5 cm.
- 6. DRILLING Advantages Disadvantages 1. Depth of soil can control. 1. Require more time, energy and cost. 2. Row to row distance can also be control. 2. Can’t control plant to plant distance. 3.Physical weed management is easy. 3. An expert technical person is required for running of a seed-drill.
- 7. DIBBLING Process in which field is divided into a plot or definite row to row distance or plant to plant distance.
- 8. DIBBLING Advantages Disadvantages 1. Control plant to plant and row to row distance. 1. Overall yield will be less 2. Production per unit area will be high. 2. Depth of sowing hard to be maintain 3. It facilitate intercultural activities like Earthing up, Weeding etc. 3. It is more laborious, time consuming and expensive.
- 9. PLANTING By using any other vegetative part to grow plant other than seed. Example : Rice, Cotton, Sugarcane etc
- 10. PLANTING Advantages Disadvantages 1. We can grow seedless crops example: Potato, Banana 1. Time and Labour consuming method 2. Control row to row and plant to plant distance. 2. Can not adopt in all crops 3.It facilitate Physical weed management 3. Costly Modern tools and implements are required
- 11. TRANSPLANTING After growing nursery plants that is more than 25 days then they are transplanted into the main field. Example : Rice.
- 12. TRANSPLANTING Advantages Disadvantages 1.Environmental conditions will be favourable. 1. Time and Labour consuming 2. More care can be provided during nursery. 2. High water requirement. 3. Production rate is high. 3. Costly Modern tools and implements are required
