Applications of mycorrhiza on potato growth and productivity

Abstract

Mycorrhiza is a root plant symbiont functioning to increase mineral and nutrients absorption. Mycorrhiza fertilization to potatoes has to be monitoredin order to observethe effects of mycorrhiza on the growth of potatoes. Therefore, theaim of thisstudy was to analyze the effect of mycorrhiza on potato growth and production. This field research was conducted in Kledung village, Temanggung (1,138 masl) from 25 March to 25 June 2018. The method used was separated block design with 4 treatments and 20 replications in each plot. The first plot (P1) was the plot without treatment; the second plot (P2), positive control, was the plot treated with chemical fertilizer;the third plot (P3) was plot treated with organic fertilizer Bokasi and Trichoderma; and the fourth plot (P4) was fertilized using mycorrhiza. The data related to growth and production were analyzed using ANOVA and Tukey's test; while, to determine the best type of fertilizer among treatments t-testwas used. The results showed that mycorrhizal application significantly increased height (20.12 cm p ≤ 0.05), the number of leaf (32.47, p ≤ 0.05), and potato production (213.70 gr). It can be concluded that the use of mycorrhiza significantly increased the growth and production of potato.
