Pengaruh Pemberian Dosis Pupuk Urea dan Variasi Jarak Tanam Terhadap Produksi Tanaman Ciplukan (Physalis angulata L.)

Abstract

This research was aimed to determine the cultivation techniques of ciplukan (Physalis angulata L.) by administering variations in the dose of urea fertilizer and spacing on the production of ciplukan plants cultivated in the field. This research was conducted from March 2020 until completion at the Jubung Agroteknopark, Jember city. This study used a factorial randomized block design with two treatment factors and three replications. The first treatment was by giving a dose of urea fertilizer, consisting of three levels N1: 1.5 g/plant, N2: 2.5 g/plant and N3: 3.5 g/plant. The second factor is setting spacing (J1) 20 x 40, (J2) 30 x40, (J3) 40 x 40, and (J4) 50x40. Each treatment was repeated 3 times. The data were analyzed using the ANOVA test and if there were differences in data then it was continued with the Duncan Multiple Range Test (DMRT) at a 95% confidence level. The results showed that the interaction was highly significant in the treatment of urea fertilizer 3.5 grams per plant with a spacing of 50 cm x 40 cm (N3J4) in the observation variable number of branches and number of harvestable fruit, and significantly different in the variable number of total fruit, number of fruit not harvestable, total fruit weight and average fruit weight. A single treatment of 3.5 gram urea per plant (N3) showed significant differences in the treatment of plant height, plant weight, and number of flowers. A single treatment with a spacing of 50 cm x 40 cm (J4) showed significantly different results on the variable number of leaves and very significantly different on the variable plant weight and number of flowers.
