Fertilizer And Weed Management In Irrigated Ecology

Fertilizer management :
• Kharif - 60-75 kg n/ha in 50:50 (fym : urea) was comparable to three splits of prilled urea along with 40 kg each of p2o5 and k2o/ha
• Rabi - 90-100 kg n with 40 kg p2o5 and k2o/ha application of n in three splits ( 50%basal, 25% at active tillering and the rest 25% at panicle initiation)
Weed management :

special agro technique of rainfed lowland ecology

1. Lower seedling density in nursery using only 40 gm seed/m2 to produce thick, healthy seedlings(40 to 50 kg /ha).
2. Correcting zinc deficiency and adding 50% more p and k in the nursery then recommended.
3. Row seeding, preferably dibbling, 20x15 cm behind plough or seed-drill.
4. Seeding time first fortnight of june for alluvial soils & second fortnight of june for laterites.
