Abstract
A field experiment was conducted at Punjab Agricultural University, Ludhiana during spring season 2020 to study the yield performance of maize (Zea mays L.) hybrids under different nutrient levels. Three nutrient levels (125:60:30, 156:75:38, 188:90:45 kg N:P2 O5 :K2 O /ha) as main plots and seven hybrids (PM 17201L, PM 17205L, DKC 9197, PM 17208L, RASI 4118, P 3522 and KMH 25K45) in sub-plots were evaluated for their influence on growth, yield attributes and yield of maize. Application of nutrients @ 188:90:45 kg/ ha resulted in significantly higher stover and grain yield (126.6 and 93.2 q/ha, respectively) as compared to the nutrients @ 125:60:30 q/ha (101.0 and 79.2 q/ha, respectively), however, it was statistically at par with nutrients @ 156:75:38 kg/ha (122.9 and 90.3 q/ha, respectively). Among different hybrids, RASI 4118 recorded significantly higher stover (129.0 q/ha) and grain yield (95.2 q/ha) as compared to others except KMH 25K45 and DKC 9197.
