Evaluation of different levels of potassium and zinc fertilizer on the growth and yield of wheat

摘要

The study pertaining to evaluation of different levels of potassium and zinc fertilizers on the growth and yield of wheat was conducted at Chakkanwali Reclamation Research Station District Gujranwala during Rabi 2015-16. Randomized complete block design with factorial arrangement used to lay out this experiment. Before sowing the seeds, the following nutrients were homogeneously incorporated into the soil; K_(1)=0kgha~(-1), K_(2)=125kgha~(-1), K_(3)=250kgha~(-1) and K_(4)=375kgha~(-1) and Zn_(1)=0kgha~(-1), Zn_(2)=5kgha~(-1), Zn_(3)=10kgha~(-1) and Zn_(4)=15kgha~(-1). Data regarding various agronomic traits (plant height, number of fertile tillers per unit area, spike length, number of spikelets per spike, number of grains per spike, 1000-grain weight, biological yield, grain yield and harvest index) of crop were recorded by using standard procedures. The data collected were analyzed statistically by adopting the computer software MSTAT C and LSD at 5% probability was used to compare the differences among treatments’ means. Application of potassium fertilizer (375kgha~(-1)) and zinc (15kgha~(-1)) significantly improved the growth and yield parameters of wheat.
