Nutrient management

Apply 1 tonne of fully decomposed FYM or compost to 20 cents nursery and spread the manure uniformly on dry soil.

Basal application of DAP is recommended when the seedlings are to be pulled out in 20-25 days after sowing in less fertile nursery soils.

For that situation, before the last puddling, apply 40 kg of DAP and if not readily available, apply straight fertilizers 16 kg of urea and 120 kg of super phosphate.

If seedlings are to be pulled out after 25 days, application of DAP is to be done 10 days prior to pulling out.

For clayey soils where root snapping is a problem, 4 kg of gypsum and 1 kg of DAP/cent can be applied at 10 days after sowing.

Application of organic manures

Apply 12.5 t of FYM or compost or green leaf manure @ 6.25 t/ha.

If green manure is raised @ 50 kg seeds/ha in situ, incorporate it to a depth of 15 cm using a green manure trampler or tractor.

In the place of green manure, press-mud / composted coir-pith can also be used.

Biofertilizer application

Broadcast 10 kg of soil based powdered BGA flakes at 10 DAT for the dry season crop. Maintain a thin film of water for multiplication.

Raise Azolla as a dual crop by inoculating 250 kg/ha 3 to 5 DAT and then incorporate during weeding for the wet season crop.

Mix 10 packets ( 2 kg/ha ) each of Azospirillum and Phosphobacteria or 10 packets (2 kg/ha) of Azophos inoculants with 25 kg FYM and 25 kg of soil and broadcast the mixture uniformly in the main field before transplanting and

Pseudomonas fluorescens (Pf 1) at 2.5 kg/ha mixed with 50 kg FYM and 25 kg of soil andbroadcast the mixture uniformly before transplanting.
