Abstract
An experiment was conducted to assess the effect of genotypes, tillage methods and plant populations on dry matter, grain yield, stover yield and harvest index of hybrid maize at research field of National Maize Research Program (NMRP), Rampur, Chitwan, Nepal during winter season of 2015/16. The experiment was laid out in strip-split plot design that consisting of two hybrids as horizontal factor (Rampur hybrid 4 and Rampur hybrid 6), two tillage methods as vertical factors (zero and conventional tillage) and four plant populations (55,555, 69,444, 85,470 and 1,01,010 plants ha -1 ) as subsub plot factors. Rampur hybrid 6 produced more dry matter as compared to Rampur hybrid 4 except early stage (30 DAS). Rampur hybrid 6 produced slightly higher grain yield (6.11 t ha -1 ) than Rampur hybrid 4 (5.88 t ha -1 ). Grain yield under zero tillage (6.25 t ha -1 ) was similar to conventional tillage (5.74 t ha -1 ). Significantly higher grain yield (6.54 t ha -1 ) was obtained from the population of 85,470 plants ha -1 than 55,555 (5.31 t ha -1 ) and 69,444 (5.92 t ha -1 ) plants ha -1 but remained at par with 1,01,010 plants ha -1 (6.21 t ha -1 ) which was similar to 69,444 plants ha -1 but significantly superior over 55,555 plants ha -1 Thus, it can be mentioned that both hybrid maize varieties
