POTENSI PEMANFAATAN PUPUK GUANO PHOSFAT TERHADAP PERTUMBUHAN DAN HASIL TANAMAN BAWANG MERAH ( ALLIUM ASSCALONICUM L.) PADA BERBAGAI TARAF PEMOTONGAN UMBI )

Abstract

Abstrak : Research on the Potential Utilization of Guano Phosphate Fertilizer on the Growth and Yield of Shallots (Allium ascalonicum L.) at Various Stages of Cutting Bulbs which has been carried out on the land of the Agricultural Extension Center Office of BPP Meuraxa, Banda Aceh City. Aims to determine the effect of several doses of guano phosphate fertilizer and various levels of cutting tubers and the interaction between the two on shallot (Allium ascalonicum L.). The design used in this study was a 4 x 4 factorial randomized block design (RAK) with 3 replications, so there were 16 treatment combinations and 48 experimental units. The results showed that: The results showed that the treatment of several doses of guano phosphate fertilizer under investigation had a very significant effect on plant height (30 and 45 DAP), number of leaves (30 and 45 DAP), tuber diameter and wind dry bulb weight. Significant effect on the parameters of the number of tubers. However, it had no significant effect on plant height at 15 days after planting. The treatment of various levels of cutting of the tubers studied had a very significant effect on the number of leaves (30 and 45 DAP), the number of tubers, the diameter of the bulbs and the weight of the wind-dried bulbs. Significant effect on plant height 45 DAP). No significant effect on plant height (30 and 45 DAP) and number of leaves 15 days after planting. There is a very significant interaction on the parameters of tuber diameter on the treatment of guano phosphate fertilizer and the level of cutting of onion bulbs. The best treatment was found in the combination of dosage of guano phosphate fertilizer and cutting level of G3P3 tubers (treatment with guano phosphate fertilizer dose of 150 grams/Polybag and cutting tubers at the level of 1/4 part).
