Better forage and grain yield quality of pearl millet (Pennisetum glaucum L.) under different irrigation water supplies and plant densities

Better forage and grain yield quality of pearl millet (Pennisetum glaucum L.) under

different irrigation water supplies and plant densities

Water shortage is a global problem reducing plant growth and productivity worldwide. Much effort is being made to reduce water consumption by crops and produce 'more crop per drop'. Field experiment included 12 treatments was conducted in split-split plot design at Agriculture Research Station, College of Food and Agriculture Sciences, King Saud University, to evaluate the effect of some agronomic practices viz, three inigation water intervals (evely 5, 7 and 9 days), two varieties [Indian cv. (exotic) and Gizani (local)] and two plant densities (280 x 10 3 and 400 x 10 3) on increasing yield and quality of Pearl millet. In both seasons of the study, results showed that a sharp increase in forage yield was achieved with inigation evely 5 days due to the increase in leaf area and leaf area index. Similar trend was also observed in forage quality viz., fat%, dgestibility % and soluble carbohydrate contents as well as crude protein percentage. The two varieties were considerably different in most of growth parameter traits and the local variety (Gizani) has surpassed the introduced one. Plant demity was also significant onmost of growth parameters. Decreasedplant demity producedthe hghest leaf area and leaf area index, whereas fresh and dq weights were increased at high plant demity. Grain yield and yield component were influenced through the hghly responsive yield fraction of grain yield per hectare, grain weight per panicle (g), 1000 grains weight (g) and number of panicles per m2. High leaf area and leaf area index were obtained with inigation water supplies evely 5 days, whle the lowest value were recorded at inigation water supplies evely 9 days.
