Effect of rain water conservation practices and mulching yield and water use efficiency (wue) on maize (Zea mays l.) Under changing climate

Abstract

A field experiment was conducted during two consecutive years of rabi 2018-19 and 2019-20 at Soil Conservation and Water Management farm of the C. S. Azad University of Agriculture and Technology, Kanpur the effect of four rain water conservation practices i.e., farmer practices, ridge and furrow, micro julkund between rows, flat sowing with earthing and three mulching vez., no mulching, organic mulching @ 4 t/ha and GM biomass mulching (Dhaincha) was studied. The results Water use efficiency was recorded 9.59 kg/ha/mm of water under ridge and furrow practice, which was higher over other practices of moisture management practice. The lowest water use efficiency was recorded under farm practice by 7.96 kg/ha/mm of water in pooled results of two years. The water used efficiency was recorded higher under green manuring biomass mulching (10.09 kg/ha/mm) as compared to other mulching treatments. The minimum water used efficiency (7.67 kg/ha/mm) was noted in no mulching practice in pooled results of two years.
