Abstract

This research was conducted to evaluate the effect of zinc, proline, and biostimulant foliar application on yield of wheat. The trial was established in the research farm of the Department of Agronomy, Bahauddin Zakariya University, Multan, Pakistan. A randomized complete block design was used with three replicates. All three treatments were sprayed on Triticum aestivum cv. Galaxy at the booting stage and results of yield were compared with control. One way analysis of variance revealed that all treatments affected wheat yield significantly. Zinc foliar application (4 mM solution) produced tallest plants (104 cm), longest spikes (13 cm), maximum biological yield (2.76 kg m-2), and heaviest 1000 grains (45.2 g). While the maximum number of grains per plant (72) and maximum grain (602 g m-2) yield was observed for biostimulant sprayed at a rate of 1.2 l ha-1 on wheat. Pearson correlation also revealed a positive correlation among yield components except for plant height and grain yield that were negatively correlated. The results revealed that foliar application of zinc, proline, and biostimulant can be used to improve yield components of wheat particularly zinc application that produced better biological and economical yield.
