Response of Kharif Maize (Zea mays L.) to Planting Methods and Nitrogen Management Approach by Leaf Color Chart

A field investigation entitled Response of Kharif Maize (Zea mays L.) to Planting Methods and Nitrogen Management approach by Leaf Color Chart (LCC) was conducted during the kharif of 2016 at the Students’ Research farm, Khalsa College, Amritsar. The soil of the experimental site was sandy loam in texture with normal soil PH and electrical conductivity, medium in organic carbon and low in available N, medium in available P and high in K. Bed planted maize had significant higher grain yield (41.86 q/ha) and yield attribute as compared to ridge (36.57 q/ha) and flat (35.95 q/ha) planted Maize, but at par with zero tillage method planted maize (39.83 q/ha). However the growth attributes, straw yield and benefit cost ratio were higher in maize sowing by zero tillage. Among nitrogen management treatment, nitrogen applied by N_LCC5 had significantly higher growth, yield and yield attributes than N_LCC4 and Control N_o whereas at par with N_LCC6.
