Abstract

Research on the effect of tuber size and use of pesticides on the growth and yield of red onion (Allium Ascalonicum L) has been carried out at the UPT Seed Parent Horticulture Kutagadung Berastagi, Berastagi District, Karo Regency, from April-June 2021. The aim of the study were to determine the optimal seed size for growth and production of red onion variety of Batu Ijo and to find out how much pesticide dose was recommended.The results showed that the best plant height influenced by tuber size was U3 (N 12) 21.8 cm and U1 20 cm. Meanwhile, the lowest was U0 of 16.2 cm. The average number of plants that were most affected by fusarium disease was P0, the treatment with the least amount of pesticide was 15.5 plants. On the contrary, the lowest average was found at the level of P3 treatment, which was only 1 plant. Disease occurs along with increasing doses of fungicides and pesticides Optimum pesticide levels are h P2 (3 g of fungicide + 3 ml of insecticide) which produced an average number of tubers of 4,208. The highest average number of tubers was found at U3 which was 5.85 and the lowest was at U0 2.56. U3 level (seed tuber size > 15 grams) is the optimum treatment level. The average production per sample is the largest in the treatment effect of U3 which is 35.89 gr and the lowest is at U0 (5.52 gr). The average production per plot of the effect of pesticide level was P3 857.3 g or 0.8573 kg and the lowest was P0 689.1 g or 0.6891 kg. The average production per plot of the effect of seed tuber size level was U3 1507.2 gr or 1.5072 kg and the lowest was U0 194.3 gr or 0.1943 gr. The average production of shallots per plot was found in the U3P3 treatment (1589 gr or 1,589 kg) and the lowest was at U0P0 (159.3 gr).

Abstract

The purpose of this study was to determine the growth response and yield of mustard greens (Brassica rapa L.) by administering liquid organic fertilizer and the right concentration to increase so as to get the best growth and best yields of mustard plants. This research was conducted in August 2022 in the village of Raya Village, Berastagi District, Karo Regency, North Sumatra Province, at an altitude of 1,300 asl. The method used in this study was an experimental method, with a simple randomized block design (RBD) consisting of 6 treatments and 4 repetitions, namely: (P0 = without POC (0 ml/l water), P1 = POC 5 ml/l water , P2 = POC 10 ml/l water, P3 = POC 20 ml/l water, P4= POC 30 ml/l water, P5= POC 40 ml/l water). The results showed that the application of liquid organic fertilizer with different concentrations had an effect on the parameters of plant height, number of leaves, leaf width, leaf length, average fresh weight and dry weight of mustard plants. Giving POC with a concentration of 40 ml/L of water gave the best results for mustard plants, namely producing plants with the highest wet weight compared to other treatments, namely 716.31 gr and dry weight, namely 53.31 gr
