    Studies on performance of maize hybrids under different planting methods in spring season
    (CCSHAU, 2016) Aashish Kumar; Kamboj, B.R.
    The present study entitled “Performance of maize hybrids under different planting methods in spring season”, was conducted in Yamunanagar district of Haryana during spring 2015. The soil of the experimental field was sandy loam, slightly alkaline in reaction, low in nitrogen, medium in phosphorus and high in potash. The experiment was conducted in split plot design with three replications which consists of three planting methods viz., ridge, flat and furrow methods of planting in main plots while five maize hybrids i.e. HM-4, HM-9, HM-10, HM-11 and HQPM-5 were kept in sub-plots. Growth parameters like plant height, dry matter accumulation and relative growth rate were found maximum under ridge method of planting followed by flat and furrow methods. The higher grain yield, stover yield, biological yield, net returns and benefit cost ratio were recorded with ridge method of planting than flat and furrow methods. However, different planting methods had no effect on quality parameters namely tryptophan, lysine, protein, nitrogen, zinc and iron content in maize grain. The periodic growth parameters viz., dry matter accumulation and relative growth rate were significantly higher with hybrid HM-10 over other maize hybrids. The hybrid HM-10 gave higher grain, stover, biological yield, net returns and benefit cost ratio. The quality parameters i.e. zinc and iron content was not affected by different maize hybrids but tryptophan and lysine content were maximum in hybrid HQPM-5, whereas nitrogen and protein content were highest in hybrid HM-4.
