摘要:
Excessive nitrogen and insufficient calcium could significantly impact peanut yields. This study investigated the effects of nitrogen and calcium fertilizers on nutrient absorption, utilization, and yield; experiments were conducted using the peanut cultivar from Xianghua 2008 in a split-plot arrangement with two calcium fertilizer levels (Ca-0: 0 and Ca-1: 568 kg CaO ha(-1)) in the main plots and six nitrogen fertilizer gradients (N-0: 0, N-45.0: 45.0, N-90.0: 90.0, N-112.5: 112.5, N-135.0: 135.0, and N-157.5: 157.5 kg N ha(-1)) in subplots between 2015 and 2016 in Changsha, China. We examine...
