Yield Response of Maize Hybrids on Different Spacing Patterns under Irrigated Areas of Punjab

Background: The present study was conducted at the Agricultural Research Farm, Lovely Professional University, Phagwara (Punjab), during the kharif seasons of 2022 and 2023. It was titled as “Maize varieties yield response on different spacing patterns under irrigated areas of Punjab”. It was an experiment to assess the effect of three maize varieties namely AHC-233, P-1899 and NHM-589 and four spacing patterns S1: 60 cm x 25 cm, S2: 70 cm x 20 cm, S3: 70 cm x 30 cm and S4: 70 cm x 25 cm, on growth, yield, physiological parameters, quality attributes and economic feasibility. Methods: The experiment was conducted in a split-plot design (SPD) with three replications. Result: The experiment result shows that, the highest performance was found in P-1899 (V2), which was significantly greater than AHC-233 (V1) and NHM-589 (V3) in terms of number of cob/plant, cob length and number of rows/cob, number of grains/row, number of grains/cob and grain yield. Interaction between varieties and spacing patterns further revealed that the best results were obtained when V2 (P-1899) was combined with S2 (70 cm x 20 cm). The findings show that V2 (P-1899) with S2 (70 cm x 20 cm) is the most promising strategy for the maximum yield in irrigated conditions of Punjab.
