Paddy cultivation-Lesson 2

Learning objectives

After completing the course

The course shall cover the scientific technique of increasing the yield of paddy, a new method of growing known as “SRI VIDHI”, the pests and the pesticides to be used, removal of weeds.

The learner will have a good understanding of using SRI method for paddy cultivation.

Curriculum

Background

Welcome to Lesson-2. In this lesson, you will learn:

  1. SRI vidhi se dhan ki kheti

Rice is the staple food of people in India, many parts of Asia such as China, Japan, Indonesia, Bangladesh, Thailand, etc. Globally, China is the leading producer of rice with India being the next. Cultivating rice using SRI method increases yield.

Cultivation of Paddy using SRI method(Video-1)

SRI method of paddy cultivation is used on hilly or high ground. It uses cow dung or organic manure.

System of Rice Intensification (SRI) is special method of rice cultivation originally developed at Madagascar in 1983.
SRI is a combination of several practices that includes changes in nursery management, time of transplanting and management of water, nutrients and weeds.
SRI emphasizes certain changes in agronomic practices from conventional rice cultivation.

Soil and seed bed preparation

Soil with good drainage and enough organic matter should be used for bed preparation.
Size of rice nursery bed in SRI method varies according to seedling requirement
Raising seedlings in egg boxes filled with vermi-compost or organic manure is advantageous.
Wet beds on land can be used with addition of organic manure

Sowing on seed beds

Seed Rate: 2 Kg / acre seeds are used to raise the seedlings. Seed rate can vary for Short duration, Medium duration and Long duration rice cultivars.
Sowing Time: Seed sowing should be done before first July.

Water Management

Minimum water during the Germination stage. Soil surface should be kept moist enough to allow seed germination.

Seed beds are irrigated every 3 days. Water management practices depend on the soil type, labor availability.

System of Rice Intensification (SRI) saves up to 40 % water and gives 10 to 15 % higher yield than other conventional method of transplanting.

Nutrient Management

Soil nutrient should be supplied preferably with FYM or compost made from biomass.
Value added bio-compost such as vermi-compost gives additional advantages.
Small quantity of Chemical fertilizer can be used for better results. Use of mixed chemical fertilizer NPK (46-46-50) is recommended.

Weed Management

Practice hand weeding in SRI nursery 7 days after sowing.
Avoid use of herbicides and Mechanical weeding.

Pest and Disease Management

Integrated pest management (IPM) in SRI method is practiced to avoid investment on plant protection chemicals. Synthetic pesticides are used only when the incidence of pest or disease is very severe.

 

Advantages

SRI method of rice cultivation increases grain yield with the same level of inputs and capital.

Reduce water, seed, and chemical fertilizer inputs make it more profitable than conventional methods of rice cultivation.

Initially it require significantly more labor mainly for preparing land and weeding operation.
