INTRODUCTION : 

SRI is the acronym for System of Rice Intensification. This method was first developed in 1983 in Madagascar. This is the method is in which there is less input but more output there by a great profit for the farmers. INTRODUCTION

What is SRI cultivation? : 

SRI is neither a new variety nor a hybrid. It is only the method of cultivating Paddy in a particular pattern. Any paddy variety can be cultivated successfully by this method. What is SRI cultivation?

Conditions for a paddy plant to achive potential & give a high yield: : 

Conditions for a paddy plant to achive potential & give a high yield: More number of tillers. Number of panicles should be high. Panicle length and the number of grains per panicle should be high. The grain weight should be high. Roots should have extensive & healthy growth.

Attributes if SRI : 

Wide planting. Less seeds.(ie, one seed/hill ) Use of markers. Transplanting young seedlings. Less water. Turning back the weeds into the soil. Using of organic manure. Attributes if SRI

Wide planting: : 

Wide spacing of the plants gets more space , air & sunlight. The spacing is 25 x25 cm. There gives 16 plants for 1 sqm. Plants gives rise to more tillers. Root would grow healthily and extensively and take more nutrients. The panicle length will be high and more number of tillers per panicle. Wide planting:

Less seed: : 

As wide spacing is adopted the seed required will be less. Reduction in cost. Quality seeds can be carefully selected. After soaking the seeds in water , the ill filled seeds that floats can be easily removed. Less seed:

Use of marker: : 

In SRI method the markers are used for the transplanting the seedlings in a uniform pattern and with equal spacing. There are different types of markers roller marker, Koundinya marker and wooden marker. Use of marker:

Transplanting young seedling: : 

One seedling should be planted per hill. This reduces the cost of nursery maintenance and seed cost. The seed should be transplanted when it is two leaf stage.(8-12 days) Nursery required is 100 sq.m Transplanting young seedling:

Less water: : 

When the field is stagnated with water the root dies due to the lack of aeration. Soil should have the soil particles, moisture and air in a fixed proportion. For the healthier paddy plant the field should not be in stagnated condition. The characteristic SRI cultivation is alternate wetting and drying. Less water:

Weed Managemant: : 

Instead of weeding the weed and throwing it outside the plot they are turned down into the soil using the weeder Advantages: (i) soil aeration. (ii) weeds gets decomposed into the soil and turns into the organic matter. Weed Managemant:

Using of organic manure: : 

SRI cultivation responds better to the organic manures rather than the chemical fertilizers. Application of FYM is a must for SRI.(6tons/acre) Green manure crops. livestock penning. Using of organic manure:

Pest managmant :

Prepration of Amrit jalam: : 

Required materials: (i) Cow urine - one Litre (ii) Cow dung - One Kilo (iii)Jaggery (organic) - 250 grams (iv)Water (chlorine free) - 10 litres Mix them with water in 1:10 ratio. It not only adds nitrogen to the plant but also repels harm ful insects and micro organisms. Prepration of Amrit jalam:

Disease Management: : 

Spray application of Pseudomonas flouorescens talc formulation @ 5g/1 three times from 45 DAS at 10 days intervals control blast, sheath blight , sheath rot and Bacterial blight, bacterial streak Spray applications of cabendazim 50 WP @ 1g/1 or Edifenphos 1ml/1 controls blast, sheath blight, sheath rot Spray application of 20% Cowdung water extract controls BB, bacterial streak Balanced application of fertilizers Disease Management:

Advantages : : 

Saving of seed cost and water. Cost of input gets reduced as chemical fertilizers and pesticides are reduced. Incidence of the pests and disease are low as the soil is allowed to dry intermittently. Tasty and healthy rice as a result if organic farming. Seed multiplication with less quantity of parent seeds. Increased grain weight. Advantages :
