Experiment Background
|
Sorghum [Sorghum bicolor L. Moench] is the king of millets and considered the fourth cereal crops after maize, wheat and rice. It is an important food, feed and fodder crop. In India, the area under Sorghum is approximately 5127 lakh ha with an annual production of about 4370 lakh tonnes and an average productivity of 952 kg/ha. (GOI, 2021). In Gujarat, it is cultivated over an area of 84.88 lakh ha with a production and productivity of 115.33 lakh tonnes and 1359 kg/ha, respectively.(GOI, 2021).
Among essential plant nutrients, N plays the significant role in augmenting agricultural productions and its deficiency limits crop production. (Aulakh and Malhi, 2005). Nitrogen use and demand is continuously increasing day by day. Since, it is highly mobile, it is subject to greater losses from the soil-plant system. (Abd EI-Lattief, 2011). Even under bet management practices 30-50% of applied nitrogen lost through different mechanism and hence, the farmer is compelled to apply more than the actual need of the crop to comensate the loss. Scheduling of nitrogen application is low cost strategy to reduce nutrient losses, so that nutrient supply is synchronized with plant demand and increases NUE. (Gehl et al., 2001). During the last few years, a number of high yielding cultivars of grain sorghum have been evolved. Cultivars of a crop plays an important role in increasing crop production but information on the response of newly evolved cultivars to split application of nitrogen is meagre. Considering these facts an experiment will be conducted for evaluation of nitrogen scheduling and cultivars on kharif grain sorghum. |
