Abstract

This study aims was to find out the estimated efficiency of the utilization of element N by soybean plants using the SPAD (Soil Plant Analysis Development) method due to increased doses of VP3 biological fertilizer and long induction of electricity. This research was conducted in the trial land of Griya Shanta, Brawijaya University, Malang and Microbiology Laboratory, Universits Islam Malang. The design used is a Simple Random Group (RAK) design with 13 treatments repeated 3 times. N uptake is calculated using the SPAD method. The results of this study showed that the application of VP3 bio-fertilizer supported by certain electrical inductions was able to compensate for the use of inorganic fertilizers and can increase the chlorophyll content shown at the best treatment, namely NL1 (NPK 100% + 30-minute electricity induction) but not real different from V2L1 treatment (VP3 200% + 30-minute electricity induction), V2L1 (VP3 200% + 30-minute induction),  V2L2 (VP3 200% bio fertilizer + 60-minute electricity induction), NL2 (NPK 100% + 60-minute electricity induction), V2L3 (VP3 200% bio fertilizer + 90-minute electricity induction), V1L1 (VP3 100% bio-fertilizer + 30-minute electricity induction), V1L2 (VP3 100% induction + 60-minute induction), While the highest treatment is V1L2 (100% VP3 bio fertilizer + 60 minutes induction) with a productivity of 5.46 Tons / ha.

Abstract

Cucumber is one of the potential agricultural commodities because it has good market opportunities. However, this is not supported by the low production of cucumbers. One effort to optimize the yield potential of cucumbers is to increase the ability of the soil to support plant growth by adding organic matter such as manure and eco-enzyme. The aim of this study was to determine the interaction between the dose of eco-enzyme and the type of manure on N uptake, growth and yield of Japanese cucumber (Cucumis sativus var. roberto). The study was conducted using a Factorial Randomized Block Design (RAK) experiment consisting of 2 factors. First factor, is the type of manure (P) consisting of 3 levels, namely P1 (Cow Manure), P2 (Goat Manure) and P3 (Chicken Manure). Second Factor consists of 3 levels, namely E1 (Eco-enzyme dose 3 L/ha), E2 (Eco-enzyme dose 6 L/ha) and E3 (Eco-enzyme dose 9 L/ha). There were 9 treatment combinations with each treatment repeated 3 times with 3 plant samples, so that 81 experimental units were obtained. Data analysis used 5% ANOVA, if it was real, it was continued with 5% BNJ. The results showed that a good trend was found in the combination of P2E2 (Goat manure with eco-enzyme dose of 6 L/ha) on all growth variables and yields of Japanese cucumbers except for leaf area 28 days after planting and fruit weight yield. Keywords : Japanese cucumber, Dosage of eco-enzyme, animal manure
