The Effect of Mycorrhiza and P Fertilizer on the Yield of Wheat Varieties Dewata 162

Alwi Cahya Sarjana

Abstract


Research on the effect of mycorrhizae and P fertilizer on wheat crop yields has been carried out from May 24 to September 5, 2021 in Gejagan Village, Pakis District, Magelang Regency, at an altitude of 760 m above sea level. The research method used a factorial experiment (4 x 3) arranged in a Completely Randomized Block Design (RAKL) with two treatment factors and repeated four times. The first factor was the mycorrhizal dose, namely 0 g/plant, 2.5 g/plant, 5 g/plant, and 7.5 g/plant. The second factor is the dose of P fertilizer, namely 25%, 50%, and 75%. Data was analyzed by means of variance. The influential results were further tested using Orthogonal Polynomials. The results showed that the application of mycorrhizae and P fertilizer had no effect on all observed variables, namely plant height, number of tillers per clump, number of productive tillers per clump, panicle length, number of seeds per panicle, dry seed weight per panicle, dry seed weight per m², and weight of 1000 dry seeds. There was no interaction between mycorrhizal dose treatment and P fertilizer dose on all observation parameters
