All irrigation systems apply water nonuniformly to a varying degree; yet the nonuniformity of the applied water can significantly affect the final yield of the crop. In our study, growth parameters, crop water productivity and yield of tomato were observed to be largely affected by irrigation uniformity. A newly designed and built linearly moved irrigation system with operating pressures (P) of P1-10psi, P2-15psi, and P3-20psi with sprinkler heights varying at h1-100 cm and h2 -150 cm from the ground were utilised in the experimental set up. Our findings indicated that minimum values of distribution uniformity (70.39%) and coefficient of uniformity (82.30%) were observed at P1h1, whereas the maximum values (88.44% and 91.17% respectively) were obtained at P3 h2. Under P3h2 treatment, the highest values of plant height (60.7 cm), stem girth (0.96 cm), number of leaves per plant (26.4), number of fruits per plant (10) and fruit yield (15.10t ha-1) were recorded. Also, the lowest yield (0.86 kg m-3) was recorded under P1 h1 treatment. However,under treatment P3h2 , CWP value of 2.00 kg m-3 was highest. The results under this experimental, environmental and similar geo-hydrological condition are recommended to operate the sprinkler irrigation system for maximum crop productivity.
