Performance of wheat cultivars under different phosphorus levels and sowing methods

Abstract

Wheat ( Triticum aestivum L) is an important grain crop cultivated worldwide. Phosphorous is an essential macronutrient element that greatly contributed to the growth and yield of wheat crops. Proper phosphorous concentration and suitable sowing methods are involved in increased growth, yield, and nutrient profiling of the wheat crop. An experiment was performed at Central Cotton Research Institute, Multan, to evaluate the application of phosphorous and different sowing methods on three different wheat cultivars i.e. Gandum-1, Sehar-2006 and Faisalabad-2008. The experiment was performed to study the impact of four different phosphorous levels (control, 60kg ha -1 , 120 kg ha -1 , 180kg ha -1 ) on three different wheat cultivars by using three different sowing methods i.e. flat, drill and bed sowing. A randomized complete block design was used to perform the experiment. Present results indicated that leaf area index, leaf area duration, crop growth rate, net assimilation rate; plant height, spike length, number of spikelets, fertile tillers, number of grains per spike, 1000 grain weight, grain yield, biological yield, harvest index, phosphorous content, protein content, oil content and chlorophyll content were significantly increased in cultivar Faisalabad-2008, phosphorous 180 kg ha -1 and bed sowing method. From present results, it has been concluded that Faisalabad-2008 is a higher yielding cultivar grown on bed sowing method with the application of phosphorous 180 kg ha -1 and this combination is more suitable to attain higher yield in the future.
