US Agriseeds - Model US 305 - Hybrid Rice Seeds

Nursery Management for hybrids is quite different from that of high yielding varieties. This is essential to economize the seed requirement and to obtain multi-tillered healthy seedlings at the time of planting. Prepare nursery area thoroughly by repeated ploughing, puddling and uniform levelling. Prepare seed beds of one-meter width and any length as per convenience and provide adequate drainage facility. Apply 250 kg FYM, 2 kg Urea, 1.5 kg DAP and 0.5 kg MOP for every 100 Sq.m. area.

Soak 6 kg of hybrid seeds in water for 8-10 hours and treat the pre-soaked seeds with carbendazim (50% WP) • 4 g/kg of seed. Incubate the seeds in gunny bags for 18-24 hours to ensure better sprouting and sow the sprouted seeds sparsely and uniformly @ 20-25 g of seed per square meter area. Total area required for sowing 6 kg of hybrid seed is 400 Sq.m.

Do not allow the seed beds to dry. When the seedlings become 2 cm tall maintain thin film of water. Need based weeding can be done and apply 1.5 kg of Urea per 100 Sq.m. area after 15 days. Take need-based plant protection measures to raise multitillered healthy seedlings. With better management, it is possible to get 4-5 basic tillers per plant in 25 days.

Transplanting
Prepare main field thoroughly by repeated ploughing followed by puddling and apply the recommended dose of FYM two weeks before transplanting. Apply 50% of Urea, complete dose of DAP and MOP a day before transplanting followed by thorough levelling. Transplant 21-25 days old seedlings at the rate of 1 seedlings per hill at 2-3 cm depth. The spacing of 20 x 15 cm is essential to ensure a plant population of 33 per square meter area.

Extensive  research work on rice hybrid by SeedWork  has resulted in the release of US 305. This hybrid is notified and have been released for cultivation in irrigated tracts of many states. Maturing in 130-135 days and average plant height 110 cm, with resistance to BLB and blast. The hybrid produces large panicles with fine (medium slender) grains and has high yielding potential. The potential yield of this hybrid is about 2.8-3 tons/Acre when grown under

normal conditions. Weed Management
Apply Pretilachlor @600ml/acre between 0-3 days after transplanting. Ensure a uniform level of 2-3 cm of water in the field for 3-4 days. Need based hand weeding has been recommended to ensure healthy crop.

Nitrogen Management
Apply 25% of the recommended dose of Urea at 30-35 days (maximum tillering stage) after planting and the remaining 25% at 70-75 days (booting stage) after transplanting.

Water Management
Maintain 2-3 cm level of water for initial 30 days and later increase the water level to 4-5 cm when the crop reaches maximum tillering stage and drain out water for 4-5 days so that emergence of late tillers can be suppressed. Drain out water completely 10 days before harvest.
