Topics discussed

Fertilizer management for rice based onSite Specific Nutrient Management (SSNM).

Weed management

Five major diseases of rice and theirmanagement

Major insect pests of rice and their

management Rice harvest, post harvest activities and

seed preservation techniques for rice



Session-1: Fertilizer management

Considering factor-

Consider ³4R´

Right time

Right rate Right place

Right source



How we determine fertilizer dose Farmers interview

Fertilizer recommendation guide &

Modern rice cultivation booklet Soil test

Nutrient Management for Rice (NM

Rice) version 1.0



Session-1: Contd. It depends on different AEZ and land topography

We consider N, P, K, S & Zn in case of rice production

We can get 2 to 3 ton/ha rice with out applying 'Nµ asit add naturally.

Appling optimum 'N' we can get double yield frombase production.

For 1 ton Rice production:

N = 14 Kg

P = 2.5 Kg

K = 16 Kg



Session-2: Weed Management Up to 90% crop loss due to weed

High fertilizer use will increase the

weed infestation Weed infestation is high in DSR field



Session-2: Contd.Major weeds in rice field-

� Motha� Shama

� Masta

� Leptochloa

� Weedy rice



Session-2: Contd.Weed Control-A) Cultural Control� Stale seed bed� Crop rotation� Rouging� Tillage system (eg-ZT)

B) Chemical controlEg- Nominee gold, Refit, Ronster etc

Session-5: Post harvest Management� Importance (Food safety, Quality

assurance, Better storage etc)

� Post harvest losses (10-15%)� Causes of loss (eg-Poor processing,Limited drying facility, Lack of storage facilities etc)

� Steps (Harvesting, drying, Bagging,Storage etc



Session-5: Contd.� Harvesting (time, appropriate ripening,

mechanical, moisture)� Field drying (Dry up to 17-18%)

�Threshing (drum power thresher andpedal thresher)

� Drying for storage (sun drying,Mechanical dryer)

� Cleaning & grading for seed (Pre

cleaning, fine cleaning and grading)� Storage technology (IRRI Super bag,Cocoon)
