Abstract

A field experiment entitled “Response of forage sorghum (Sorghum bicolor L. Moench) to nutrient management during kharif season” was undertaken during Kharif, 2022 at Post Graduate Instructional Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra). The experiment was laid out in randomised block design with three replications. The experiment consists of ten treatments involving T1 –Absolute control, T2 – GRDF (5 t ha-1 FYM + 100:50:40 kg ha-1 N, P2O5 , K2O), T3 – GRDF + Water spray, T4 – GRDF + Urea @ 2%, T5 – GRDF + DAP @ 2%, T6 – GRDF + WSF 19:19:19 @ 1%, T7 – GRDF + WSF 17:44:00 @ 1%, T8 – GRDF + WSF 13:00:45 @ 1%, T9 – GRDF + WSF 00:52:34 @ 1%, T10 – GRDF + WSF 00:00:50 @ 1%. The yield contributing attributes such as green forage yield (60.70 t ha-1 ) and dry forage yield (12.3t ha-1) were significantly higher under application of GRDF along with foliar application of 19:19:19 @ 1% at 30 and 45 days after sowing. The economics of forage sorghum production was significantly influenced by the foliar nutrition. The application of GRDF along with foliar application of 19:19:19 @ 1% at 30 and 45 days after sowing recorded significantly higher gross returns (₹ 121400 ha-1 ) and net returns (₹ 81028 ha-1 ). Based on results obtained, it could be concluded that, application of GRDF (5 tonne ha-1 FYM + 100:50:40 kg ha-1 N, P2O5 & K2O) along with foliar application of 19:19:19 @ 1% at 30 and 45 days after sowing was found beneficial for increasing productivity and forage quality of forage sorghum cv.

Conclusion

Among all the treatments, the GRDF + WSF 19:19:19 @ 1% found significantly superior in terms of plant growth and yield of forage. Regarding the quality of forage sorghum produced from different treatment spraying of GRDF + WSF 19:19:19 @ 1% found superior in terms quality of forage sorghum. The cost of cultivation was low in absolute control followed by GRDF (100: 50: 40 kg ha-1 N: P2O5: K2O + FYM 5 t ha-1) but the maximum net monetary return (81028 ₹ ha-1) and B: C ratio (3.00) was observed in GRDF + WSF 19:19:19 @ 1%. It could be concluded that application of GRDF (100: 50: 40 kg ha-1 N: P2O5: K2O + FYM 5 t ha-1) along with two foliar sprays of 19:19:19 @ 1% is at par with GRDF + WSF 13:00:45 @1% and GRDF + DAP @ 2% at 30 and 45 DAS to forage sorghum found beneficial for increase of growth, yield, quality, economic returns and nutrients status in soil grown on medium deep black soil
