questions: asking about field preperation 
 answers: 1. field preparation

prepare the land to fine tilth and apply  12.5 t fym/ha

2. seed treatment

treat the seeds with carbendezim (or) thiram @ 2g/kg of seed 24hrs before sowing (or) with talc formulation of trichoderma viride @ 4 g/kg seed (or) pseudomonas fluorescens @ 10 g/kg seed. biocontrol agents are compatible with biofertilizers. first treat the seeds with biocontrol agents and then with rhizobium. fungicides and biocontrol agents are incompatible.

the above seed treatment will protect the seedlings from seed borne pathogens in the early stages. 

seed rate 
•co 3 - 90 kg/ha.
•co 4 - 75 kg/ha.
as a pure crop to have an optimum plant population 325000 / ha   

3. seed treatment with biofertilizer


treat the  seeds with  one  packet  (200  g/ha) of  rhizobial  culture (200 g/ha) of phosphobacteria developed at tnau using rice kanji as binder. if the seed treatment is not carried out apply 10packets of rhizobium (2 kg/ha) and 10 packets(2 kg) of phosphobacteriawith 25 kg of fym and 25 kg of soil before sowing. dry the biofertilizer treated seeds in shade for 15 minutes before sowing.


4. fertilizer application

a)  apply fertilizers basally before sowing.
    rainfed : 12.5 kg n + 25 kg p2o5 + 12.5 kg k2o +10 kg s*/ha
    irrigated : 25 kg n + 50 kg p2o5 + 25 kg k2o + 20 kg s*/ha
               *note : applied in the form of gypsum,  if single super phospate is not applied as a source of phosphorus
b)   soil application of 25 kg znso4/ha under irrigated condition      

5. sowing

dibble the seeds by adopting the spacing of 30 cm x 10 cm.

6. weed management



•pre emergence application of pendimethalin @ 2.5 litres on 3rd day after sowing using backpack/ knapsack/rocker sprayer fitted with flat fan nozzle using 500 litres of water for spraying one ha followed by one hand weeding on 25 - 30 days after sowing. 
•if herbicide is not applied give two hand weedings on 15th and 30th day after sowing.
