Impact of Three Input Factors at Different Levels of Management on Yield Components and Yield of Basmati 385 Rice

Muhammad Yusuf, M. Maqsood, M. Ashraf and M. Ashraf Rathore    

Abstract: Impact of three input factors such as plant density tillage profile and fertilizer were studied on farmer`s field of Sadhoke, District Gujranwala during the year 1993 and 1994. The results of the experiments conducted both the years revealed that the mean highest grain yield of 4.95 t ha -1 was obtained when all the three input factors were adopted at recommended levels against 2.08 t ha -1 from farmer`s level of inputs respectively. The highest mean contribution was due to fertilizer 1.23 t ha -1 (42.4%) followed by plant density as 0.88 kgs ha -1 (29%) and tillage profile, 0.69 kgs ha -1 (21.9%). The mean highest net return and benefit cost ratio of Rs. 8998 and 2.7 : 1 respectively were found from recommended or researcher`s technology whereas the minimum net return was of Rs. 711 from that of farmer`s level of technology.
