Abstract

East Nusa Tenggara is dominated by dry land which has the potential for the development of horticultural crops. Horticultural plants that are widely cultivated by the community are spinach. However, in reality, spinach production in this province is still fluctuating, this is due to the low knowledge of farmers about providing proper nutrition for plant growth and development. For this reason, this study aims to determine the production of spinach in dry land due to cow manure and atonic application. This research was conducted in the experimental field of the Faculty of Agriculture, University of the Teachers Association 1945. The design used was a factorial randomized block design (RBD), which consisted of 2 factors: factor I: cow manure and factor II: growth stimulant (atonic). The results obtained were: The application of cow manure and atonic manure to spinach on dry land had a very significant effect on plant height (7,55 -F hitung> 4,77-F Tabel), number of leaves (10.85-F hitung> 4,77-F Tabel), fresh weight (13,98-F hitung) > 4,77-F Tabel) and dry weight (6,44 -F hitung) > 4,77 -F Tabel).

Abstract

Long bean (Vigna sinensis L.) is a vegetable commodity containing 2.70 mg protein, 2.30 mg fat, 44 cal calories, 7.80 mg carbohydrates, 347 mg phosphorus, 47 mg calcium, 335 SI vitamin A, 0.39 mg B vitamins. , 21 mg of vitamin C and 88.50 mg of water. Production of Vigna sinensis L in NTT in 2019-2021 continues to increase but the phenomenon of rising long bean prices indicates that long bean production needs to be increased. One of the efforts made is to increase the availability of soil nutrients through fertilization. The aim of the study was to determine the interaction effect of NPK dosage and young coconut water concentration on the yield of long bean plants. The research was conducted in June-July 2022 using the Randomized Block Design (RBD) experimental method with 2 factors and 3 treatment levels, namely: Factor I = NPK Fertilizer (A) and Factor II = Concentration of young coconut water (K). The results obtained: The treatment of NPK fertilizer and young coconut water had a very significant effect on the growth components of long bean plants as indicated by differences in plant height, number of leaves, number of pods and pod weight. The interaction between the application of NPK fertilizer (NPK 250 kg/ha) and the concentration of young coconut water (90% /1L) gave the best results giving the best results on the average plant height, number of leaves, number of pods and pod weight of long bean plants.
