Abstract
The growing water demand has raised serious concern to the future of irrigated agriculture in many parts of the country. Therefore, the knowledge of crop water demand is an important practical consideration to improve the water productivity in irrigation practices. The traditional irrigation systems provide unnecessary irrigation to one part of a field while leading to a lack of irrigation in other parts. Changing environmental conditions and shortage of water have led to the need for a system which efficiently manages irrigation of fields. Based with this background a field experiment was conducted at Water Technology Centre, PJTSAU, Hyderabad (India) to study the effectiveness of sensor based irrigation system on water productivity and yield of maize. The experiment was laid out in a split plot design replicated thrice with twelve treatments using DHM-117 as a test variety of maize. The results revealed that the amount of total water applied under drip irrigation through nano sensor (IITB) based readings was 322 mm against the surface furrow irrigation of 494 mm. Drip irrigation shown comparatively higher water productivity (1.96 kg m-3) compared to surface furrow irrigation (1.15 kg m-3) and among the schedules higher water productivity (1.53) was associated with nano sensor (IITB). Simultaneously, nano sensor (IITB) based irrigation system recorded the highest grains per plant (184.13 g), cob weight per plant (243.65 g) and grain yield (7.05 t ha-1) of maize.
