Chlorophyll, crop growth rate and forage yield of Brachiaria (Brachiaria brizantha Stapf) as the result of goat manure in various nitrogen dosage

Abstract

growth rate (CGR), forage yield, dry matter ((DM) yield and DM content of BrachiariabrizanthaStapf. The experiment used manure (0 and 5 ton/ha) and nitrogen dosage (50, 100, 150 kg N ha-1) set in factorial design 2 x 3, repeated three times. The result showed that manure increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content. N dosage increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content. The interaction between manure and N dosage increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content. The result showed that manure usage and nitrogen dosage 150 kg N ha-1 increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content in the amount of 27.5; 20.5; 98.4; 68.5; 103.4 and 20.5% compared to without manure and nitrogen dosage in the amount of 150 kg N ha-1
