The Pengaruh Pemberian Pupuk Bokashi Feses Ayam Broiler Dan NPK Terhadap Pertumbuhan Dan Hasil Tanaman Sawi Caisim (Brassica Juncea L.)
Abstract
Mustard plant (Brassica juncea L.) as one of the horticultural plant species from the Brassicaceae family which has great potential to be cultivated in Indonesia. The productivity of mustard greens has decreased due to several factors, one of which is the insufficient nutrients needed by plants during the vegetative and generative stages of the plant. In addition, the factors that affect the cultivation of mustard plants are declining soil quality, uncertain climate change, and attacks by plant-disturbing organisms (OPT). With this problem, it is necessary to add nutrients to the soil, the added nutrients are organic fertilizer bokashi broiler chicken feces and inorganic fertilizer NPK. The purpose of this study was to determine the effect of the interaction between broiler feces bokashi fertilizer and NPK fertilizer on the growth and yield of caisim mustard plants. The research method used a completely randomized design (CRD) which consisted of 2 factors with 3 replications. The first factor of bokashi fertilizer consists of 3 levels, namely B1: 25 grams/polybag; B2: 30grams/poly bag; B3 : 35 gram/poly bag. The second factor is NPK fertilizer which consists of 3 levels, namely N1: 0.63 gram/polybag; N2: 0.47 gram/poly bag; N3: 0.31 gram/poly bag. The data obtained was analyzed using Analysis of Variance (ANOVA), and if it was significantly different, it would be further tested by Duncan's Multiple Range Test or Duncan's Multiple Range Test (DMRT) with a 95% confidence level. The results showed (1) the interaction of broiler feces bokashi fertilizer and NPK fertilizer showed a significant difference in plant height and plant fresh weight variables and other variables showed no significant different effect. (2) Broiler faeces bokashi single fertilizer treatment gave significantly different results on root length and plant fresh weight variables with the best dose being B3 : 35 gram. (3) the single fertilizer treatment gave highly significant different results on the number of leaves variable and not significantly different on the growth rate variable and chlorophyll content variable with the best dosage being N3: 031 gram.
