Abstract

This research aims to find out the influence of liquid organic fertilizer concentration on the growth and production of mustard pakcoy (Brassica rapa L.). The research was conducted in Jiken village, Tulangan District, Sidoarjo Regency and plant physiology laboratory of Muhammadiyah University of Sidoarjo in July to September 2020. This research using RandomIzed Group Design (RAK) was compiled in a single factor, namely the concentration of liquid organic fertilizer with a level of 25%, 50%, 75% and repeated 3 times so that there are 30 units of experiments. The observed variables are: plant height (cm), leaf area (cm2), number of leaves (strands), wet weight (grams), antioxidant activity (ppm). The data was analyzed using ANOVA followed by BNJ test at 5% test level. The results showed no noticeable influence on the variable height of the plant and the area of the leaves. In variable number of leaves and wet weight there is a noticeable influence on the treatment of liquid organic fertilizer concentration 75% application as much as 4 times at the observation age of 35 days with the average yield of the number of leaves (17.33 strands) and wet weight (92 grams). Antioxidant activity tests showed the best results in the control treatment with the lowest value (174,779 ppm) because the lower the IC50 value, the better the antioxidant activity.

Abstract

The need for soybeans is very high, but not balanced by soybean production. Recorded in 2014, the government should import kedelei of 67.28% of the national soybean demand. Therefore, sustainable agricultural system is needed to increase soybean production. The aim of this research is to know the combination of treatment of biological fertilizer (Rhizobium) and compost (azolla and straw). The experiment was conducted in Panjer village, Mojosari sub-district, Mojokerto, from April to July 2017. The research used randomized block design (RAK) factorial design with 2 factors. Factor 1 was rhizobium (without rhizobium (R0) and rhizobium (R1)) and factor 2 is the application of compost fertilizer (without the application of compost fertilizer (K0), azolla compost fertilizer (K1), the application of straw compost fertilizer (K2) and the composting of azolla compost and straw compost (K3)). From these two factors, 8 treatment combinations were repeated 3 times. Data were analyzed by multiform analysis followed by 5% duncan test. The results showed that the treatment combination was not significantly different, but the compost treatment showed that azolla compost was able to increase both vegetative and generative growth, whereas in biofertilizer was able to increase wet weight of root nodule but did not affect the increase of other observation parameters.
