v
New spider species (15 Nos.)
described. Cultural practices
conserving spiders in rice probed. v
Seed treatment with Trichoderma viride (4
g/kg of seed) or Pseudomonas fluroscens (10 g/kg of seed)
followed by soil application of Trichoderma viride or Pseudomonas
fluroscens @ 1 kg/ac on the 25th and 45th DAS
effectively control the root rot disease in gingelly. v
Irrigation one day after disappearance
of ponded water (DPW) in dry season (kharif) and three days after DPW in wet
season (rabi) recorded higher yield and water saving in rice when compared to
continuous submergence. v
Rice-Rice-Sesame was the viable cropping system in v
Allowing the blackgram to second and
third flesh recorded 80 to 100 per cent yield increase. v
Water requirement for different crops were worked
out and recommended. v
Application of BGA increased the rice
grain yield by 14 to 21% wherein azolla application increased yield of 14 to
22% over untreated control. |
