“…The increase in all these characters in T 1 might be due to the availability of all the resource at adequate amount at T 1 crop management practice, which helped in higher photosynthetic and metabolic activities of plant, resulting increase in cob parameter, which directly helps in increasing yield. The findings can be corroborated with the findings of Asghar et al, (2010), Thavaprakaash et al, (2008), Randhawa and Khan (2007) and Thakur et al, (1997). Plant spacing significantly influenced the grain yield of maize.…”
