Improving Chinese kale (Brassica oleracea var. alboglabra) Productivity and Profitability in Low-Fertility Soils through Organic Amendments and Planting Distance Management
Abstract
Chinese Kale cultivation in Dadaprejo, Bumiaji, which is a vegetable production center in Batu City and its surrounding areas is still not optimal due to low soil conditions in C-organic and nitrogen content. The soil texture tends has a low water holding capacity. The purpose of this study was to observe the quantity and quality of Chinese Kale through organic approach and planting spacing on low-fertile soil. The factorial experiment designed used Randomized Block Design with 2 factors and 3 replications. The first factor consists of 4 levels of chicken manure dosage: 0 tons ha-1 (M0); 5 tons ha-1 (M1); 10 tons ha-1 (M1) and M3: 15 tons ha-1. Second factors were 3 levels of planting spacing of 20 cm x 20 cm (S1); 25 cm x 25 cm (S2) and 30 cm x 30 cm (S3). The results showed that there was no interaction between chicken manure dosage application and the space planting distance on the growth and yield of Chinese Kale. Chicken manure dosage treatments did not show any significant effect on the growth and yield of Chinese Kale. Applying 30 cm x 30 cm space showed the best results in CGR and yield variables (the total plant fresh weight of 9.55 t ha-1 and the edible fresh weight of 9.20 t ha-1). Although it is still unable to meet the potential of the variety description, the results of the harvest quality analysis and the farming feasibility analysis indicate the potential for Chinese Kale cultivation with organic inputs and the application of planting distance compared to the control.
