Abstract

Field experiment on irrigation and quality characters of maize was conducted during summer 2021. The field was laid out with Factorial Randomized Block Design (FRBD) with as inter cropping of pulses were assigned as a main factor (A) viz., lablab, green gram, black gram, cowpea and maize. Irrigation a sub factor (B) with 75% PE, 100% PE, 125% PE along with flooding as check irrigation. Normal irrigation practices were followed for flooding and volume of water was quantified using parshall flume. Irrigation was given once in three days interval from 1st day to 75 days after sowing. Yield was positively responded based on the amount of irrigation given at various stages during the crop growth. Lesser irrigation and higher the amount of irrigation than the normal had lesser yield on maize compared to other irrigation as a treatments. Maize + Black gram cropping system recorded the highest number of grains per row (34.1) and least number of grains per row was recorded in Maize + Cowpea cro

Keywords

Potential evapo-transpiration. Yield, Yield attributes, Irrigation Quantity.

Conclusion

The present study concluded that irrigation under flooded condition doesn’t give the potential yield attributes of maize. Maize intercropped with pulses under drip irrigation gives better yield attributes and drip irrigation is the best suitable tool for cultivation of maize under future climatic scenarios.
