Nutritional quality, nutrient uptake and biomass production of Pennisetum purpureum cv. King grass

Abstract The research was conducted to determine the effects of cutting interval and fertilization on the nutritional quality, nutrient uptake, and biomass production of King grass. The experimental design was a randomized complete block, using 4 blocks and 8 treatments per block; treatments consist...
