Abstract

One effort to improve the quality of superior seeds is to optimize cultivation techniques using foliar fertilizers. This study aims to determine the effect of the concentration of Gandasil B fertilizer and spraying intervals on the production and quality of mung bean seeds. This research was conducted in September 2022 - December 2022 at the Jember State Polytechnic Jl. Koptu Berlian, Antirogo, Kec. Sumbersari, Jember Regency, East Java, East Java. The experimental design used was a factorial randomized block design (RBD) with 2 treatment factors and 3 replications. The first factor was the treatment of several concentrations of foliar fertilizer with 3 levels, namely 6 grams/liter (P0), 8 grams/liter (P1) and 10 grams/liter (P2). The second factor is the spraying interval which consists of 5 days (I1), 10 days (I2) and 15 days (I3). The data will be analyzed using ANOVA and continued DMRT test level of 5%. The results showed that the concentration of Gandasil B foliar fertilizer had a very significant effect on the number of pods per plant parameter with the highest average P0 (9,68 fruit), significantly different from the pod weight parameter with the highest average P0 (7,35 grams) and production parameters per hectare P1 (0,52 tons). The spraying interval treatment had a very significant effect on the number of pods per plant parameter with the best treatment I3 (9,57 fruit), significantly different effect on the pod weight parameter per plant with the highest average I3 (7,76 grams) and the production parameters per hectare with the highest average I3 (0,5 tons). The interaction of treatment concentrations and spraying intervals of Gandasil B foliar fertilizer had a very significant effect on the parameter of the amount of production per hectare with the best treatment P1I3 (0,655 tons), then had a significantly different effect on the parameter of the number of pods per plant. with the highest P1I3 average (10,67 fruit) and P1I1 pod weight parameter per plant (8,42 gram).
