Hasil dan Kualitas Tomat pada Pemberian Pupuk Mikotricho dan Pupuk N-P-K

Abstract

The research objective was to determine the effect of the application of Mikotricho bio-fertilizers and N-P-K fertilizers on the yield and quality of tomatoes. The research was conducted from May to October 2020. The experiment used a factorial treatment in the screenhouse. The design used was a completely randomized block design (CRBD) with 3 replications.  The first factor is the dosage of Mikotricho biofertilizer, namely 10 g, 30 g, and 50 g plant^-1. The second factor was a reduction in the dose of N-P-K fertilizer, namely a reduction of 0%, 25%, 50% of the recommended doses and control (without Mikotricho fertilizer and without N-P-K fertilizer). Data were analyzed using analysis of variance and further test of LSD 5%. The results showed that the application of micotricho fertilizers in tomato cultivation could increase fruit volume and fruit yield of plant^-1 at a dose of 30 g plant^-1 and without reducing N-P-K fertilizers in the form of urea, SP-36 and KCl from recommended dosage. For the number of fruit of plant^-1, the application of micotricho fertilizer at a dose of 30 g plant^-1 can be increased by reducing the dose of N-P-K by 25%. The application of micotricho fertilizer at a dose of 30 g plant^-1 can also increase the vitamin C content and reduce N-P-K fertilizer by up to 25%, while the sugar content in fruit increased at 10 g plant^-1 micotricho fertilizer.
