Evaluation of Growth of Different Maize Varieties in Field under the Climatic Conditions of Peshawar

Abstract

A field experiment on “Evaluation of maize varieties under the climatic condition of Peshawar” was conducted at Agricultural Research Institute Tarnab (ARI) during Kharif season 2012. The experiment was conducted in Randomized Complete block Design (RCB). emergence was non significant those plot sown with Iqbal taken maximum days to emergence of (7) days while plot sown with pop-2011 taken minimum days to emergence of (4) days . Higher emergence ­­­­­m­-²(8) was recorded for pop-08 and Jalal showed lowest (3) emergence ­­­­­m­-².   Jalal took (53) days to tasseling while Pir sabaq evaluation showed the lowest (46) days to tasseling among the different maize varieties. Analysis of the data indicated that days to silking were significantly affected by maize varieties. Minimum (52) days to silking were observed in pop-2011 while maximum (56) days to silking were observed in Sarhad white.Lowest plant height was observed in jalal (160 cm) while highest plant height was recorded  in pop-07 (184 cm). Different varieties have different plant height, lowest cob height was observed in jalal (48 cm) while highest cob height was recorded in pop-09 (66 cm). Minimum (76) days to physiological were observed in pop-2011 while maximum (81) days to physiological maturity were observed in Sarhad white. Minimum (90) days to harvest maturity were observed in pop-2011 while maximum (97) days to harvest maturity were observed in Sarhad white. maximum 1000 grain weight was recorded for pop-2011 (275 g) while minimum 1000 grain weight was recorded for Iqbal (227 g).Statistical analysis of the data revealed that the data for grain yield was significant those plot sown with Jalal have the minimum grain yield of (1500 kgha^-1) while plot sown with pop-2011 have the maximum grain yield of (4666 kg ha^-1).
