Abstract:
Field experiments were conducted at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirapalli under rice fallow season 2016 and 2017 to select a suitable green gram variety and to optimize the seed rate for higher productivity of rice fallow green gram under sodic soil. The experiments were laid out in split plot design with three replications. The main plot treatments comprised of five green gram varieties (ADT 3, VBN 2, VBN (Gg) 3, Co(Gg) 7 and Co(Gg) 8) and the sub plots were three levels of seed rate (25, 30 and 35 kg/ha). The results revealed that the green gram variety Co(Gg) 8 registered higher plant population per m², yield attributes and grain yield. However, it was comparable with ADT 3. Green gram sown at 35 kg/ha seed rate registered significantly higher plant population per m², yield attributes and grain yield over 30 and 25 kg/ha. Hence, green gram variety, Co(Gg) 8 sown at 35 kg/ha recorded higher productivity, net returns and BC ratio under rice fallow condition in sodic soil.
