RESPONSE OF FODDER SORGHUM TO CUTTING AND NITROGEN MANAGEMENT UNDER SOUTH GUJARAT CONDITION
Research Type
Departmental Research
Experiment Background
Live stock is very important part of our rural economy. India rank first among the major livestock population of the world. The low productivity of Indian livestock is mainly due to chronic shortage of feed and fodder coupled with poor quality. In Gujarat, total animal population is 18.44 million heads and the area under forage crops is only 0.8 mhi.e. 6.4% of the total cultivated area. The total annual production of forage is only 20 MT against requirement of 49.2 MT.Fodder sorghum is one of the most widely adopted fodder crop. It can be fed as green and dry fodder or conserved into silage especially for lean period. Due to its excellent growing habit, high yield potential and better nutritive value, it is extensively growth throughout the country. The main constraints of low production of forage sorghum are poor management practices and less availability of improved seed of fodder sorghum. Considering the above facts and views, the present experiment is planned.
