Integrated nutrient management in oat (Avena sativa L.) under reclaimed sodic soil

Oat (Avena sativa L.) is used as a green fodder, straw, hay or silage. A field experiment was carried out during 2007-2008 and 2008-09 with the concept of integrated nutrient management at Aurawan Research Centre of National Botanical Research Institute, Lucknow. The treatments of the experiments were T1- Control, T2- NPK (80:40:40), T3- ? NPK (40:20:20) + FYM (10 t/ha), T4- ? NPK + FYM (10 t/ha) + Trichoderma, T5- ? NPK + FYM (10 t/ha) + PSB and T6- ? NPK + FYM (10 t/ha) + Trichoderma + PSB with 4 replications in randomized block design (RBD). Results indicated that maximum plant height at 120 days (157.7 cm), tillers/plant at 90 days (6.42), length of spike (38.7 cm), test weight (28.57 g), grain yield (34.92 q/ha), straw yield (82.77 q/ha) were recorded with T2- NPK (80:40:40 kg/ha) which was significantly higher than all the treatments, followed by treatment T6- ? NPK + FYM (10 t/ha) + Trichoderma + PSB showing the value of plant height at 120 days (154.8 cm), tillers/plant at 90 days (6.32), length of spike (37.6 cm), test weight (28.32 g), grain yield (34.12 q/ha) and straw yield (81.10 q/ha). Seed treatment with PSB (T5) also responded significantly over control in all the parameters. However, combined seed treatment with PSB + Trichoderma (T6) was much effective in comparison to single inoculation of Trichoderma or PSB.
