Abstract

This study aims to determine the effect of interactions as well as the main factors of biological fertilizers and rock phosphate fertilizers on the growth and production of shallot plants. This research was carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City. The study was conducted from September to November 2022. The design used in this study was a factorial Completely Randomized Design (CRD) with two factors. The first factor is biological fertilizers consisting of 4 treatment levels, namely 0; 0.6; 1,2; and 1.8 g per polybag and the second factor is rock phosphate fertilizer consisting of 4 treatment levels, namely 0; 0.5; 1; and 1.5 g per polybag, so there are 16 treatment combinations with 3 replications, so there are 48 experimental units. Parameters observed were plant height, harvesting age, number of tubers, wet tuber weight, dry tuber weight, tuber weight per tuber, tuber diameter and tuber weight loss. Observational data were analyzed statistically and continued with the BNJ follow-up test at the 5% level. Based on the results of the research that has been done, it can be concluded that the interaction of biological fertilizers and rock phosphate fertilizers has a significant effect on all parameters where the best treatment is 1.2 g of biological fertilizers per polybag and 1.5 g of rock phosphate fertilizers per polybag. The main effect of real biological fertilizers on all observation parameters, the best treatment at 1.8 g per polybag. The main effect of rock phosphate fertilizer was significant on all observation parameters, the best treatment was 1.5 g/polybag rock phosphate fertilizer.
