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

Active ingredients or also known as activators have an important role in  decomposition process of materials during composting. The active ingredient acts as a catalyst that breaks down the lignocellulose contained in the main ingredients of compost into simpler chain. In this research, the active ingredients used in the composting process are Beta and Eco Farming. The advantages of these two active ingredients in addition to acting as active ingredients are also rich in nutrients needed by plants. The nutrients produced from this decomposition process will be compared with the established standard, namely the Indonesian National Standard (SNI) 19-7030-2004. The results of the analysis showed that the macronutrient content of the two active ingredients in the pellet compost product made from cow feed was in accordance with the standards set with the values of nitrogen (>0.4%), phosphorus (>0.1), and potassium (>0, 2). the c-organic content is in the standard range that has been set (9.8%-32%). The percentage of water content is below the maximum water content that has been set (50%). The acidity level (pH) for pellet compost with Beta active ingredients is in the standard lifting range with value of 7.17 while pellet compost with Eco Farming active ingredients has a pH of 7.88 which is close to the maximum standard value of 7.48. The number of C/N ratio is still higher than the standard set so that it takes a longer time in the fermentation process so that the appropriate number is obtained.

Abstract

Karo regency is center for carrot (Daucus carota L.) production in North Sumatra. It is estimated more than 1% of the rejected carrot yields are produced in each planting period. With the predicted harvest area, more than 1,000 tons of rejected carrots will be produced annually. This potential can be used as the material for the manufacture of liquid organic fertilizer (LOF). There are three research variables that were carried out, namely: 1) Independent variables consisting of fermentation periode consisting of 10 days, 20 days, 30 days and 40 days. 2) Fixed variable consisting of 4 kg of rejected carrots, 5 liters of water, 5 liters of old coconut water, 0.6 liters of brown sugar water, 0.05 kg of yeast, 0.5 liters of EM-4. 3) Bond variables consist of C-Organic content, Phosphorus content, Potassium content  and Nitrogen and pH content. The results showed that the peak of microorganism activity occurred on the 30th day. This treatment obtained the highest proportions of 0.07%, 0.14%, 0.87%  for Nitrogen, Phosphorus and Potassium levels respectively. The highest C-Organic content was obtained in the H-20 and H-30 treatments with a proportion of 1.55%. The acidity level was stable at a value range of 3.5 from the start to the end of the quenching process. LOF carrots produced are still not in accordance with established quality standards. The percentage value of macro elements, C-Organic and pH is still below the set quality standards.
