Field observations :

Bagabasa Gram Panchayat area

Swarna Mashuri and Pooja varieties

Square planting, 22 – 25 cm

Tillers per plant 25- 35 (ave. 30)

Water stagnation by rain but draining

First hand weeding by rotary weeder

2. Mr. Chowdhary (Sonapur) Aman rice – planted with SRI methods Seed rate – 2 kg/ac (conv. 25 kg/ac) Seedling – single (conv . 5-6/hill), 10 d old seedlings (conv. 30 days) NPK fertilizer – 65 kg/ac (conv. 175 kg/ac) Three rotary weedings – 12, 24 and 36 DAT (conv. 2 hand weedings); AWD irrigation No lodging; reach maturity 5-7 days earlier, but pest attack is more in SRI

Paddy yield expected from present aman crop: 40 mond/kani - 3.8 t/ac (9.5 t/ha) Constraints: Labour problem especially for weeding Time-bound operations

Paddy yield expected from present aman crop:

40 mond/kani - 3.8 t/ac (9.5 t/ha)

Constraints:

Time-bound operations

3. Mr. Amirthalal Das, Indhiranagar 10 d old seedlings, single seedlings, square planting, 25 x 25 cm spacing Rice yield 40 panicles/hill, 38 mond/kani – 3.8 t/ac (conv. yield 1.8 t/ac -- 9.5 vs. 4.5 t/ha) Yield >doubled; cost reduced; 15 days earlier maturity; low pest pressure; good grain filling; low chaff (few unfilled grains); maximum tillering; only labour is a problem

After the field visit, 6 presentations were made by delegates S.No Name of delegate Topic 1 Dr. V. Ravindra Babu, DRR, Hyderabad Grain quality assessment in SRI BPT 5204, DRRH-2, Swarna Eco-SRI, SRI and Traditional Only varietal difference in grain quality No influence by management effect except few parameter, viz., amylose content Results need to be confirmed

Grain quality assessment in SRI

BPT 5204, DRRH-2, Swarna

Eco-SRI, SRI and Traditional

Only varietal difference in grain quality

No influence by management effect except few parameter, viz., amylose content

Results need to be confirmed

S.No Name of delegate Topic 2 Dr. K. Surekha, DRR, Hyderabad Nutrient uptake and soil mining study in SRI Low NUE and yield in Eco-SRI SRI & conventional NPK uptake on par SRI & conventional yields -- no difference No soil depletion after 2 seasons of SRI No clear varietal difference exists on NUE Soil-available K more in Eco- SRI Results need to be confirmed

Nutrient uptake and soil mining study in SRI

Low NUE and yield in Eco-SRI

SRI & conventional NPK uptake on par

SRI & conventional yields -- no difference

No soil depletion after 2 seasons of SRI

No clear varietal difference exists on NUE

Soil-available K more in Eco- SRI

Results need to be confirmed

S.No Name of delegate Topic 3 Dr. K. Karthikeyan, Kerala Pest incidence in SRI Jyothi & KRH–2 evaluated Stem borer moderate level Rice blue beetle - more under SRI Leaf folder and whorl maggot reduced in SRI Increased activity of natural enemies, viz., spiders and larval parasites Only one season of data, results need to be confirmed

Pest incidence in SRI

Jyothi & KRH–2 evaluated

Stem borer moderate level

Rice blue beetle - more under SRI

Leaf folder and whorl maggot reduced in SRI

Increased activity of natural enemies, viz., spiders and larval parasites

Only one season of data, results need to be confirmed

S.No Name of delegate Topic 4 Dr. G. Ravi, TNAU, Tamil Nadu SRI and IPM Stem borer, BPH, whorl maggot, gall midge reduced under SRI Only leaf folder is more under SRI Increased activity of predatory spiders IPM fits very well with SRI

SRI and IPM

Stem borer, BPH, whorl maggot, gall midge reduced under SRI

Only leaf folder is more under SRI

Increased activity of predatory spiders

IPM fits very well with SRI

S.No Name of delegate Topic 5 Sardar Iqbal Singh, Farmer, J & K Used marker, 25x25 cm spacing, 15 d seedlings, pulling out of nursery very easy, conventional method laborious, AWD irrigation, full NPK applied, cono weeder 20 th day Variety: PC 19 35-55 tillers/hill Ave. yield: 4.5 to 5.0 t/ha

S.No Name of delegate Topic 6 Mr. Gopal Swaminathan Agricultural graduate cum farmer Shared his experiences on: Double transplanting technique with SRI to mitigate extremely hot climate in Cauvery Delta Innovative method of planting rice on ridges (direct seeding) in ridge-furrow system

Field study ….

Serious discussions going on …..
