摘要： Regardless of the application of inputs i.e. chemical fertilizers, plant protection measures and irregular irrigations, wheat cultivated areas of Pakistan are commonly low yielded due to late seeded of wheat under our cotton-wheat cropping system. Contemporary experiment in field was laid out to examine the response plant growth promoters through artificial application on late seeded wheat at experimental area of Faculty of Agriculture, University of Agriculture, district Faisalabad in wheat sowing season 2019-20. There were four plant growth promoters viz. Indole Acetic Acid (IAA); Moringa Leaf Extract (MLE); Gibberellic Acid (GA(3)) and Indole Butyric Acid (IBA) were artificially applied with various approaches viz. seed priming and spray application (both); seed priming and spray application. This experiment was conducted in factorial arrangement of randomized complete block design (RCBD) replicated thrice. The size of plot of experiment was remained 4.5 mx2.4 m (L*W). Outcomes of experiment indicated that priming technique of wheat seed with GA3 eloquently improved seed emergence attributes i.e. mean germination time (MET), time to start germination, time taken to fifty percent germination and index of germination as compared to Moringa Leaf Extract and Indole Acetic Acid. Similarly combination of both priming + spray application of moringa extract eloquently enhanced yield attaining parameters i.e. No. of grains per spike, No. of productive tillers, grain yield and 1000-grain weight by 16%,28%, 29% and 18%, respectively, in comparison to Gibberlic acid. Outcomes of this experiment shown artificial treatment of IAA, IBA and MLE eloquently improved the yield of late seeded wheat crop. This advantage was credited to more accumulation of metabolites, healthy growth and development, lower oxidative damage and relative water contents. Benefit cast ration analysis shown that moringa extract was the greatest economical for increasing the wheat production and clear profit of late seeded wheat. In said view, exogenous use of plant growth promoters eloquently increased the production of late seeded wheat in Pakistan.
