PENGARUH KONSENTRASI PUPUK ORGANIK CAIR NASA DAN KONSENTRASI GA3 PADA PERTUMBUHAN DAN HASIL TANAMAN BUNCIS BABY (Phaseolus vulgaris )

Abstract

The bean plant is one of the well-known horticultural plants and is widely consumed by the people of Indonesia. Beans plants are also one of the plants that have ample sources of vegetable protein and vitamins. To increase the production of beans, it can be done by choosing the right fertilizer to maintain soil fertility, namely the use of organic fertilizers. The use of liquid organic fertilizer Nasa is considered capable of providing complete micro and macro elements for plants and their absorption is faster than solid organic fertilizers such as manure, compost, besides that the application of growth regulators (ZPT) is also very necessary for plants to support their growth. This study used NASA Liquid Organic Fertilizer (POC NASA) and Zpt Gibberellins on Bean Plants. This study used a factorial Randomized Block Design (RAK), which was arranged with 2 factors, namely factor I in the form of fertilizer concentration P1 : 2 ml/l (P2); 4 ml/l (P3); 6 ml/l . Factor II in the form of Gibberellin GA3 concentration: 50 ppm (G1); 100 ppm (G2); 150 ppm (G3). Observation parameters include, plant length (cm) number of leaves (strands), stem diameter (mm), leaf area (cm), number of pods (fruit), total weight of pods planted (g), pod length (cm), plant wet weight. (g), plant dry weight (g). Data analysis using ANOVA followed by the Least Significant Difference Advanced Test (BNT) at the 5% level. Based on the analysis of variance showed that there was no interaction between treatments. The best treatment was obtained at the concentration of POC nasa 2-4 ml/l and gibberellins 100 ppm but not significantly different.
