Head Cabbage

Abstract The aim of this study was to examine the effect of human urine on soil quality and salinity through repeated applications, and compare it with the effects of synthetic fertilizer and non-fertilized treatments. Six different fertilizer mixtures were applied to pots of head cabbage: 100% tap water, 100% urine, 1:1 urine and tap water, 1:2 urine and tap water, 1:3 urine and tap water, and synthetic fertilizer. The study design was completely randomized design (CRD) with three replications of pot-based experiments. The growth and yield parameters of producing head cabbage (Brassica oleracea) among treatments were compared. Soil residual test of the optimum treatment was also conducted for the optimum treatment to examine the effect on its characteristics. The optimum yield was obtained from the application of 1:3 of urine and water, and comparable to the synthetic fertilizer (F = 21.78; p = 0.964). The difference in the electrical conductivity of soil was statistically significant (F = 2.324; p = 0.049) after three rounds of applications which should be considered during urine fertilizer utilization. Generally, urine contains nutrients, which can substitute synthetic fertilizer, at a dilution factor of three. However, education should be delivered to enhance public acceptance and to create awareness on urine collection, storage and application for sustainable utilization.

[EFFECT OF WEED COMPOST AND SYNTHETIC FERTILIZER DOSAGE ON TOMATO GROWTH AND YIELD (Lycopersicum esculentum Mill.)]. The growth and yield of tomato plants are influenced by fertilizer and nutrient content in the soil. This study aims to investigate the effect of a combination of synthetic fertilizer and weed compost on the growth and yield of tomato plants. The study was conducted in November 2016 through June 2017 in Agronomy, Faculty of Agriculture, University of Bengkulu, at an altitude of ± 10 m above sea level using a Completely Randomized Design (CRD). The treatments consisted of  synthetic fertilizer at a rate of  180 kg/ha N, 150 kg/ha P2O5 and 100 kg/ha K2O (control), grass compost 30 , 40 and 50 tons/ha, 50% control + grass compost 15 tons/ha, 50% control + 20 tons/ha grass compost and 50% control + 25 tons/ha grass compost. The results revealed that the vegetative growth of tomato plants fertilized with grass compost 30 tons/ha and a combination of grass compost + 50% control did not differ from control treatment. Tomato yield fertilized with grass compost 30 tons/ha and a combination of 50% control + 15 tons/ha grass compost was higher than the control treatment. Therefore, 15 tons/ha of grass compost can reduce the dose of synthetic fertilizer by 50%.

Abstract: The objective of this work was to evaluate the growth and yield of teak (Tectona grandis) stands at different spacing and in different soil classes. Twelve spacing were evaluated in an Inceptisol and Oxisol, in plots with an area of 1,505 or 1,548 m2, arranged in a completely randomized design with nine replicates. The teak trees were measured at 26, 42, 50, and 78 months of age. Total tree height was less affected by spacing. Mean square diameter was greater in wider spacing, whereas basal area and total volume with bark were greater in closer spacing. An increase in volume with bark per tree was observed with the increase of useful area per plant. For teak trees, growth stagnation happens earlier, the growth rate is higher in closer spacing, and the plants grow more in the Inceptisol than in the Oxisol.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.
