A proper fertilizer and crop management practices are required. The relationship between different level of nitrogen fertilizer, growth and pineapple fruit yield vary N36 were studied. The experiment was conducted using randomized complete block design of seven treatments with four replicates, Prior to artificial flower induction, seven different rates of nitrogen fertilizer at 0, 200, 400, 600, 800, 1,000 and 1,200 kg-ha^-1 were applied in four equal split doses. As the level of nitrogen fertilizer was increased, a decrease in acidity of fruits and an increase in crown weight were observed. However an increase in mean length of D leaf, mean fruit length, mean fruit weight, mean fruit to crown ratio were obtained as the rate of nitrogen fertilizer was increased from 0-600 kg.N-ha^-1. Further increase however led to a decrease in the same parameters.展开更多
