在半干旱热带地区,高粱是一种耗养作物,并且是一种主要的粮食作物。钾肥对高粱是不可缺少的,因为它具有提高产量、品质和抗各种环境胁迫的能力(Tandon 等,1988)。由于缺少关于雨养高粱钾营养的资料,因此,进行了在雨季钾肥对高粱产量的影响的研究。1988年在海得拉巴城,雨季种植了2个高梁品种(SPV462和杂交种 CSH5),随机区组设计,8次重复。土壤为中等深度淋溶土,有效 In the semi-arid tropics, sorghum is a food-for-work crop and is a major food crop. Potassium fertilizer is indispensable for sorghum because of its ability to increase yield, quality, and resistance to various environmental stresses (Tandon et al., 1988). Due to a lack of information on potassium nutrition in rain-fed sorghum, studies were conducted on the effects of potassium on sorghum production in the rainy season. In 1988, two sorghum cultivars (SPV462 and hybrid CSH5) were planted in the Hyderabad city in the rainy season. Randomized block design was used and eight replicates were conducted. Soil is medium-depth leaching soil, effective
