This literature review, which covers the period 1960 to 1983, is concered with the response of grain sorghum to all soil nutrients, related soil and climatic conditions, and the seasons in which the crop is grown. The main objective is to quantify the responses and their relationship to different environments. However, the results clearly demonstrate the widespread deficiency of nitrogen (N), phosphorus (P), and zinc (Zn) under both rainfed and irrigated conditions. High-yielding cultivars have shown greater responses than local cultivars and, invariably, both N and P have shown additive effect. Split appliction of N is generally more efficient than a single-dose application. When the N technique is used it has been observed that about 62.5% fertilizer N is recovered by sorghum from Alfisols and 55% from Vertisols. Drilling of phosphte proved more efficient than broadcasting. The responses to potassium (K) are rather rare, except in long-term experiments. Responses to the appliction of Zn are reported, especialy in vertisols when the available Zn is about 1.0-1.2 ppm or less. In the postrainy-season crop the responses to N are dependent on the nature of the cultivar and the nitrate-N level if the soil. The optimum level of nitrogen for sorghum varies from 60 to 120 kg/ha N in the rainy season, 25 to 85kg/ha N in the postrainy season, and 80 to 150kg/ha N in the summer season. A finding of the review is that most of the publications reviewed report the results of the so-called rate-and-date type of agronomic (...)
