Technologies developed

Rice

• Wet seeding practice by drum seeder registered higher net income of Rs.18,587/ha with BC ratio of 2.29 over traditional transplanting (Rs. 15,825/ha and 1.93). The yield recorded in transplanting (5.58 t/ha) was on par with seeding by drum seeder (5.66 t/ha).

• Application of N based on LCC critical value 4 registered the highest yield of 7.61 t/ha closely followed by LCC critical value 3 (7.10 t/ha) in improved White Ponni.

Sorghum

• Application of recommended inorganic fertilizers (RIF) + FYM @ 10 t/ha and 75 % RIF + Bio fertilizers significantly increased the grain and straw yields in sorghum.

• Application of pre emergence herbicide Metalochlor @1 kg ai/ha found to be effective to control the weeds and increased the yield and net income of sorghum intercropping with pulses (Cowpea / Blackgram/ Greengram).

• Application of recommended dose (60 kg/ha) of N (50% through FYM + 50 % through urea) with 50 % P and K along with seed inoculation of biofertilizer (Azospirillum + phosphobacteris) recorded the higher grain and straw yield than recommended inorganic NPK (60:30:30 kg/ha). Sowing of short duration (95 d) ragi variety DPI 2011 after the initial dry spell gave a good yield of 2415 kg/ha and higher net income compared to long duration variety (Paiyur 1) sown in first rain received.

• Seed treatment with Tricyclazole (Beam) @ 8 kg/ha of seed reduced the incidence of ragi blast.

Samai

• Application of 6.25 kg ZnSO4 and 12.5 kg FeSO4 enriched with FYM registered highest grain yield of 595 kg/ha.

• An integrated package involving 40:20:0 NPK kg/ha coupled with 5 t/ha FYM for samai has accounted the highest yield and net return with improved soil N fertility status.

Pulses

• Application of sulphur 30 kg/ha (Gypsum 200 kg/ha) along with the recommended dose of NPK (12.5:25:0 kg/ha) found increased the grain yield and net income.

• Soil application of vermicompost 2 t/ha with seed treatment of T.viride @ 4 g/ha recorded less incidence of root rot in horsegram.
