Forage Yield and Quality of Barley as Influenced By Nitrogen Application and Harvest Dates

M. Ayub, I. A.P. Dewi and A. Tanveer

Abstract:
A pot experiment was conducted to study forage yield and quality of barley when harvested at different times (88, 106, 129, 143, 154 and 178 days after sowing) and grown under three nitrogen (0, 50, 100 kg ha–1). Fresh, dry matter and crude protein yields and quality parameters i.e. crude protein percent and modified acid detergent fibre percent were influenced significantly by nitrogen rates and harvest times. Whereas, dry matter percent was only influenced significantly by harvest times. The interaction between harvest times and nitrogen level were also significant for all parameters except for crude protein yield and plant height. Crude protein (CP) percent in whole barley plant decreased with time and remained constant near maturity. Modified acid detergent fibre percent increased with harvest date and reached a maximum at the fourth harvest and then decreased significantly by the fifth harvest. Maximum dry matter (727.7 g) and fresh yields (2184.4 g) were observed at fifth and fourth harvest respectively. The barley fertilized at 100 kg ha–1 and harvested 154 days after sowing seems to be optimum combination for getting higher dry matter yield.
