Effect of Fodder Cutting Management on Quality of Different Varieties of Oat (Avena sativa L.)

Abstract

The present study aims to study the effect of cutting and splitting of nitrogen management on the quality of different varieties of fodder oat (Avena sativa L.). The field experiment was conducted at the Genetics and Plant Breeding farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.), India during Rabi 2019-2020. The experiment was carried out with three treatments consisting of three varieties (RO-19, JHO-851, UPO-212) and four fodder cutting and splitting of nitrogen viz. (T1) Two cuttings (55 DAS & 50% flowering) + 60% N as basal + 40% N at Ist cut; (T2) Two cuttings (55 DAS & 50% flowering) + 50% N as basal + 50% N at Ist cut; (T3) Three cuttings (55 DAS, 35 days after 1st cut & 50% flowering) + 50% N as basal + 25% N at Ist cut + 25% N at IInd cut and (T4)Three cuttings (55 DAS, 35 days after 1st cut & 50% flowering) + 40% N as basal + 30% N at Ist cut + 30% N at IInd cut were laid out in split plot design with three replications. As per the results, the values of RO-19 obtained the highest Crude fibre (%), Digestible crude protein (%), Total Digestible Nutrient (%), and Water soluble carbohydrates (%) as compared to JHO-851 and UPO-212. As regarded cutting and splitting of nitrogen management on Crude fibre (%), Digestible crude protein (%), Total Digestible Nutrient (%) and Water soluble carbohydrates (%) were found maximum under Three cuttings (55 DAS, 35 days after 1st cut & 50% flowering) + 50% N as basal + 25% N at Ist cut + 25% N at IInd cut.
