Abstract

The reasearch aimed to examine the effect of water hyacinth compost fertilizer dosage on the growth and yield of pakcoy (Brassica rapa L.) on various planting media. The research was conducted from February 2022 to April 2022 at the Green House of the Food Plant Protection and Horticulture Agency of Central Java Province and the Laboratory of Plant Ecology and Production, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The research design used was a 4 x 3 factorial completely randomized design (CRD) with 3 replications. The first factor (P) consisted of 4 levels of water hyacinth compost dosage, namely P0 = control, P1 = 25 tons/ha, P2 = 30 tons/ha and P3 = 35 tons/ha. The second factor (K) consists of several types of planting media, namely K0 = soil, K1 = soil + husk charcoal (3:1) and K2 = soil + cocopeat (3:1). Parameters observed were plant height, number of leaves, fresh weight and dry weight of plants, root length, root weight, total chlorophyll and harvest index. The data obtained were tested using the Analysis of Variance (ANOVA) and the results that significantly affected the observed parameters were then further tested using Duncan’s Multiple Range Test (DMRT) at the level 5%.The results showed that the dose of 25 tons of water hyacinth compost fertilizer with soil planting media can increase the growth and yield of pakcoy (Brassica rapa L.) the highest and most efficiently. Keywords: dose, compost fertilizer, pakcoy

Abstract

Increased productivity of soybean (Glycine max L. Merrill) can be done through balanced and integrated fertilization. Rock phosphate and guano are natural sources of phosphor as an alternative to TSP fertilizer which has the advantage of not having a residual effect. The solubility of phosphor in natural phosphate is slow to be available. CMA inoculation can be done as an effort to increase the solubility of phosphor nutrients in natural phosphate. The aim of this study was to examine the response of soybean growth and yield due to CMA inoculation and natural phosphate fertilization, namely rock phosphate and guano. The research was conducted in January 2022 – April 2022 at the Greenhouse of the Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The study design used a monofactor completely randomized design (CRD) with the treatments being natural phosphate fertilization and CMA inoculation with 6 treatment levels (T1:TSP; T2:BP; T3:Guano; T4:TSP+CMA; T5:BP+CMA; T6:Guano+CMA). The treatment was repeated 8 times, so that 48 experimental units were obtained. The treatment was repeated 8 times, so that 48 experimental units were obtained. The research variables included plant height, number of trifoliate leaves, flowering age, dry weight of straw, number of filled pods, and dry weight of seeds. The data were analyzed by analysis of variance, then if it had a significant effect, it was continued with Duncan's multiple distance test (DMRT) at 5% level. The results showed that CMA inoculation treatment and natural phosphate fertilization could increase plant height, number of leaves, number of filled pods, and dry weight of seeds.Keyword: guano, mycorrhizal,  phosphate, soybean
