Study on Production and Productivity of Oat (Avena sativa L.) Crop as Influenced by Different Organic and Inorganic Nutrient Managements under Mid – Hill Region of Himachal Pradesh

Abstract

Aim: To study on production and productivity of oat (Avena sativa L.) crop as influenced by different organic and inorganic nutrient managements under mid – hill region of Himachal Pradesh. Study design: The field experiment was conducted in randomized block design (RBD). Place and duration of study: A field experiment was carried out during 2022-2023 with the concept of integrated nutrient management at Abhilashi University Chail chowk Mandi (H.P.). Methodology: Seven treatments were evaluated in randomized block design with three replications. T1 – Control, T2 -50% NPK (N40 P20 K20), T3- 75% NPK (N60 P30 K30), T4-100% NPK (N80 P40 K40), T5- 50% NPK + FYM 10 t/ha, T6-75% NPK + FYM 5 t/ha, T7-75% NPK + FYM 10 t/ha. Results: The higher growth of oat crop could be achieved by adopting integrated nutrient management (T7 -75% NPK + FYM 10 t/ha) proved significantly superior to other treatments. The minimum value of growth parameters was recorded under control. Results revealed that higher yield attributes viz. No. of effective tillers, Spike length, No. of spikes, Grains per spike, test weight, were recorded under T7-75% NPK + FYM 10 t/h and lowest were recorded under T1-control. Yield parameters viz. grain yield, straw yield, biological yield was highest recorded under T7- (75% NPK + FYM 10 t/ha) and lowest were recorded under T1- control. Conclusion: On the basis of one season study, it can be safely concluded that the application of 75% NPK + FYM 10 t/ha superior in terms of growth and yield.
