Abstract

 
 
 Field experiment was carried out to study the effect of different tillage systems and skipping irrigation at different growth stages along with or without foliar applied potassium on phenology, growth and yield of maize hybrid. Results revealed that maximum grains per cob (381), 1000-grains weight (281.00 g), grain yield (7.82 t ha-1) and biological yield (14.78 t ha-1) were observed in conventional tillage system as compared to zero tillage. Regarding the irrigation levels and potassium (K) spray maximum grains per cob (390), 1000-grains weight (309 g), grain yield (8 t ha-1) and biological yield (15.33 t ha-1) were recorded with full irrigation + 1% Sulphate of Potash (SOP) spray. Skipping irrigation at tasseling stage had the most negative effect on yield attributes. Foliar application of SOP at 1%with full irrigationsunder conventional tillage system significantly improved the phonological and yield attributes of autumn planted maize.
