Assessing performance of maize (Zea mays L.) hybrids under different regimes of irrigation and organic manure in semi arid region of Haryana

A field investigation was conducted in a sandy loam during the spring 2020 at CCS Haryana Agricultural University Hisar, Haryana to study the effect of irrigation source and organic manure source's on performance of maize (Zea mays L.) hybrids. The treatments consisted of two single cross hybrids (HQPM-1 and HQPM-5) and two irrigation sources [Canal water and treated sewage water] in main plots and four organic manure sources [No manure, 100% recommended dose of nitrogen (RDN) through FYM, 100% RDN through vermicompost and 50% of RDN through FYM + 50% of RDN through vermicompost] in sub-plot. The higher growth parameters and yield of maize were recorded in HQPM-1 as compared to HQPM-5. Treated sewage water performed statistically at par in different growth parameters and significantly higher in yield of maize, in comparison to canal water. Application of 100% RDN through vermicompost resulted in significantly higher plant height, dry matter accumulation per plant, yield (grain, straw and biological) of maize as compared to rest of the treatments. This study concluded that treated sewage water can be a replacement to the conventional water sources under use and application of 100% RDN through vermicompost can improve the growth and yield of maize.
