Yield performance of normal and late sown wheat in response to seed priming and foliar applied nutrients

Abstract

An investigation was carried out to determine the impact of seed priming i.e. non-primed and primed seed with 2.0% KCl for 12 hr and twice foliar nutrition i.e. no spray, 0.5% ZnSO₄, 0.5% CaCl₂, 0.5% KNO₃, and 2.0% urea on yield execution of normal sown (November 28) and late sown (Late sown) wheat. The results revealed that in both years of study, wheat planted on November 28 produced significantly higher grain yield with a comparable difference in number of spikes per square meter, spike length, number of fertile spikelets per spike, number of grains per spike, and 1000-grain weight. There was 23.0% and 24.0% decrease in grain yield for the late sowing on Late sown when compared with normal sowing on November 28 in first year and second year, respectively. Primed seeds were not significantly impacted in comparison to the non-primed seed. In contrast with no spray, spraying of various nutrients twice at maximum tillering and 80% flowering recorded significant improvement in yield of wheat crop. Highest yields were recorded with a foliar spray of 2.0% urea followed by 0.5% ZnSO₄, 0.5% KNO₃, and 0.5% CaCl₂. The significant interaction between sowing dates and foliar spraying demonstrates that foliar spray of urea at the rate of 2.0% and ZnSO₄ at the rate of 0.5% at maximum tillering and 80% flowering stage were financially more reasonable choices for both the planting dates and can increase grain yield.
