Title : Productivity, Profitability and Water Use Efficiency of Sweet corn (Zea mays L. saccharata) as Influenced by Irrigation Scheduling

Abstract :

This field study was conducted at Research Farm of AICRP for Dryland Agriculture at College of Agriculture (RVSKVV), Indore (MP) during the rabi 2019-20 and 2020-21. Irrigation scheduling (IW: CPE) consisted three different level viz., 0.6 IW: CPE, 0.8 IW: CPE and 1.0 IW: CPE with 6 replications in Randomized Block Design (RBD). Irrigation was applied through drip system having inline emitter of 4 lph (Litre per hour). Results revealed that among the irrigation scheduling, 1.0 IW: CPE recorded the taller plants (188.70 cm), maximum dry matter/plant (179.50 g) and number of leaves/plant (12.70) which was followed by 0.8 IW: CPE. Similarly, irrigation at 1.0 IW: CPE recorded the highest values of number of cobs/plant (2.67), cob length (29.5 cm) and weight of cob without husk (311.90 g) followed by 0.8 IW:CPE and 0.6 IW:CPE. 1.0 and 0.8 IW: CPE scheduling increased green cob yield by 10.9 and 9.3 per cent over 0.6 IW: CPE scheduling. Among the irrigation scheduling, 0.8 IW: CPE gave maximum net returns of ₹255796/ha and B:C ratio of 5.73. The maximum WUE (38.41 kg/ha-mm) followed by 47.32kg/ha-mm and 57.70 kg/ha-mm were observed in 1.0 IW:CPE, 0.8 IW:CPE and 0.6 IW:CPE, respectively. Harvested rainwater in the farm pond can be used for high remunerative crops i.e. sweet corn for obtained the better profit. Hence, it is concluded that for getting higher production and net returns from rabi sweet corn can be achieved by adopting proper irrigation scheduling from harvested rainwater.
