Aplikasi Pupuk Organik Cair Rebung Bambu Dan Fosfor (P) Terhadap Pertumbuhan Dan Produksi Tanaman Sorgum (Sorghum Bicolor L.)

Abstract

This study aims to determine the application of Liquid Organic Bambu and Phosphorus (P) Bambu Shoot Organic Fertilizer on the Growth and Production of Sorghum Plants. This study used a factorial randomized block design (RCBD) with 2 factors, the first factor was the provision of Organic Bamboo Bamboo Liquid Fertilizer with 4 levels, namely R0: without treatment (Control), R1: 200 ml, R2: 400 ml, R3: 600 ml and factors the second provision of Phosphorus (P) with 3 levels, namely P0: without treatment (Control), P1: 2.5 g, P2: 5.0 g. There were 12 treatment combinations that were repeated 3 times yielding 36 experimental units, the number of plants per plot of 8 plants with 4 sample plants, the total number of plants 288 plants with a total sample of 144 plants. The parameters measured were plant height, number of leaves, stem diameter, leaf area, the number of branches initiated, panicle length, grain weight per sample, plot weight, 100 grain weight. The data from the observations were analyzed using analysis of variance (ANOVA) and followed by Duncan's mean difference test (DMRT). The results showed that the application of Bamboo Shoot and Phosphorus POC had no effect on plant height, number of leaves, stem diameter, leaf area, the number of branches initiated, panicle length, grain weight per sample and weight of 100 ears. Meanwhile, the application of bambu shoots and phosphorus POC had an effect on grain weight per plot. The interaction between the two treatments did not have a real effect
