Determinants of Wheat Productivity in Irrigated Balochistan

Abstract: The survey was conducted in two districts of irrigated Balochistan i.e., Nasirabad and Jaffarabad from 73 farmers. The farmers allocated over 46 % of their holdings to wheat production during 1999-2000. However, the area under wheat crop declined by 5.2 % during Rabi 1999-2000. Relatively greater reduction (13.1 %) in wheat acreage was recorded in Jaffarabad district than that in Nasirabad district. Both bassal and top dressing methods were used by the farmers. The farmers used fertilizer both at the time of sowing and with first irrigation mostly with N as a second dose, but the quantity far below the recommended 120-60-90 NPK. Late sowing and weed infestation was found as the second major cause of low yield. Lodging and rust contributed in yield loss due to using tall varieties which was found 1.3 and 1.3 % respectively in both the districts. Farmers used only 12.1 and 10 kg of N and P per acre as basal dressing during Rabi 1999-2000. The rate in Basal application was low, 10 kg N and P, while in top dressing the rate of N was high i.e., 15.7 kg but no phosphorus. As top dressing farmers in irrigated Balochistan were only applying N at the rate of 15.7 nut Kg per acre. Fertilizer rate was highest in Nasirabad for basal dressing as compared to Jaffarabad district using more fertilizer as top dressing. Irrigated Balochistan experienced a decline of 2.4 mounds acre -1 in its wheat yield during Rabi 1999-2000 on overall basis The yield in Jaffarabad district remained unchanged whereas Nasirabad district experienced inclines of 4 mounds acre -1 in wheat yield during the year 1999-2000 due to high rate of fertilizer.
