Impact of Different Levels of Phosphorus and Seed Inoculation With Arbuscular Mycorrhiza (AM) On Growth, Yield Traits and Productivity of Wheat

THE GOAL of the present investigation was to assess the effect of phosphorus levels and arbuscular mycorrhizal inoculation on growth, yield related traits, productivity and phosphorus uptake by wheat. Two field experiments were conducted using a split plot design with 3 replications in 2016/2017 and 2017/2018 winter seasons. Five levels of P-fertilization (0%, 25%, 50%, 75% and 100% of the recommended dose) were randomizly arranged in main plots and the two treatments of mycorrhizal inoculation “without inoculation (M_0) and with inoculation (M1)” were plotted in the sub plots. The results showed that, the yield related traits (number of grains spike^-1, number of spikes m^-2 and 1000-grain weight) significantly higher with 100% P level in both seasons. Arbuscular mycorrhizal inoculation gave the highest yield related traits in both seasons. Increment levels of phosphorus increased the grain, straw yield and harvest index significantly up to 100% P level of wheat crop. Increasing level of P application (0 to 100% P level) and inoculation with arbuscular mycorrhiza significantly increased P concentration in grains and uptake of P in wheat in both seasons. The combined application of 100% P level with arbuscular mycorrhizal inoculation recorded significantly higher phosphorus uptake in both seasons.
