Effect of Inoculation with Mycorrhizae, Phosphorus Levels, and Humic Acids on some Components of Wheat Yield

Abstract

Abstract Mycorrhizal inoculation (M1) produced the greatest number of grains per spike (36.5 in number) and gained the greatest weight of 1000 grains (36.32 g). The percentage of harvest index achieved its maximum value at ha-1. The biological yield reached its highest at 34.02%, with a quantitative optimum of 14.12 tons ha-1. Furthermore, the application of P2 phosphate fertilizer resulted in the maximum measured weight of 1000 grains (37.50 g), the highest measured number of grains per spike (38.06 grains spike -1), and the highest measured grain yield (5.31 tons). The biological yield was measured at 14.75 tons ha-1, representing the highest value. Additionally, the harvest index revealed that this yield was the highest at 36.52%. Furthermore, the introduction of humic acid H2 resulted in the weight of 1000 grains reaching 37.47 g and the number of grains per spike reaching their maximum values. Humic acid H2 produced the maximum grain yield, measuring 5.31 tons ha-1, at a rate of 38.67 grain spikes per square hectare. The value of the biological produce reached at 14.55 tons.ha-1, while the highest percentage in the harvest index had a 41.56% reduction in its value. The greatest value was produced by the second interaction treatment M1P2. We determined the peak value for the number of grains per surge to be 38.62, with a weight of 39.09 g for 1000 grains. Spike-1, and it most significantly increased the grain yield by 5.50 tons.ha-1, the biological yield by 14.99 tons.ha-1, and the percentage by which it increased the grain yield by the most substantial quantity. The harvest index achieved a value of 36.56%. The triple interaction M1P2H2 demonstrated superior performance by achieving the highest values for grain yield (6.31 tons ha-1) and grain yield per spike (43.95 grains spike-1). Additionally, this treatment yielded the highest value for grain weight (43.95%) and number of grains per spike (43.95%).
