Abstract
Wireless sensor network is an important technology in agriculture to enhance the efficiency, productivity and profitability of farming with minimal use of inputs. Maintaining uniformity of soil moisture throughout the crop growth is of greater importance to achieve maximum yield. Hence, a field experiment entitled “WSN based irrigation management in beans” was conducted at ZARS, GKVK, Bengaluru during kharif 2021. This study was aimed to know the effect of sensor based irrigation management on the performance of beans, water saving and water use efficiency (WUE). For the sensor based irrigation treatment, irrigation was provided when available moisture in the soil was depleted for about 25-30 per cent. Results indicated that, sensor based irrigation recorded significantly higher beans yield (6972 kg ha-1) which enhanced crop yield by 18.87 per cent and saved water to the tune of 26.66 per cent over conventional method of irrigation. This could help farming community to boost income.
