RESPON PERTUMBUHAN DAN HASIL TANAMAN BAWANG MERAH (Allium ascalonicum L.) TERHADAP PEMBERIAN BERBAGAI DOSIS PUPUK KOMPOS Azolla microphylla DAN PUPUK PHOSPAT

Shallots (Allium ascalonicum L.) is one of the leading horticultural commodities and has been cultivated by farmers intensively. Along with the increase in population, the need for shallots also continues to increase. The production of shallots has decreased, one of the causes is the excessive use of inorganic fertilizers, thus giving a negative impact on the soil and causing a decrease in the productivity of shallots. Efforts to improve the soil so that the nutrients needed by plants can be met and increase the production of shallots are by giving organic fertilizers and giving inorganic fertilizers that are not excessive. The purpose of this study was to determine the effect of growth and yield of shallot (Allium ascalonicum L.) on the application of various doses of Azolla microphylla compost and phosphate fertilizers and determine the appropriate dose. This research was conducted in an integrated land of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang from November 2020 to January 2021. This study used a factorial randomized block design (RBD) consisting of 2 factors then the data will analyzed using analysis of variance (ANOVA) and test BNJ 5%. Shallots plants responded to the application of Azolla microphylla compost and phosphate fertilizer. The application of Azolla microphylla compost had a significant effect on the parameters of plant height, number of leaves, tuber diameter, fresh weight and dry weight of shallot bulbs and had no significant effect on the number of shallot bulbs. The application of phosphate fertilizer did not significantly affect all observation parameters
