Abstract

The aim of the study was to determine the response time of growth and production of long bean (Vigna unguiculata sesquagpedalis) to the incubation time of organic fertilizer Taspu and POC Punica on Red Yellow Podzolic Media. This research was carried out in the experimental garden of the Faculty of Agriculture, Islamic University of Riau. This research was conducted for three months from May to July 2022. This study used a completely randomized design (CRD) which consisted of two factors. The first factor was the incubation time, there were 4 treatment levels 0, 7, 14, 21 days and the second factor was the dose of POC Punica 15, 20, 25 Cc per liter of water. Each treatment consisted of 3 replications so that 48 experimental units were obtained. In the experimental unit there were 4 plants and 2 were used as observation samples which were taken randomly to obtain 192 plants. Observational data were analyzed statistically and carried out by Follow-Up Test for Honest Significant Differences (BNJ) at the 5% level. The results showed that the interaction of incubation time of Taspu organic fertilizer and Punica POC significantly affected the observed parameters, namely plant height, flowering age, harvest age, number of pods planted, longest pod length, weight of pods planted, weight of 100 seeds, chlorophyll content and average leaf color value. The best treatment was found at the incubation time of 21 days before planting and POC Punica 28 cc/l of water.
