Abstract

This study entitled The Effect of NPK Fertilizer Dosage and Shallot Litter on the Growth and Yield of Shallots (Allium ascalonicum L.), this study aims to analyze the effect of doses of NPK fertilizer and shallot leaf litter on the growth and yield of shallots, which be held from July - September 2021. The research was carried out in Polo, Kenteng, Nogosari, Boyolali with an altitude of 152 meters above sea level. The type of soil used is regosol soil. This study used the Completely Randomized Block Design (CRBD) method which was arranged in a factorial manner consisting of 9 treatments, each treatment repeated 3 times. The fertilizers used are NPK fertilizer and onion leaf litter. The data from this study were analyzed by using the LSD (Least Significant Difference) test at a level of 5%. Parameters observed included plant height, number of leaves, weight of wet stover, weight of dry stover, number of tubers per clump, weight of wet tuber per clump, weight of dry bulb per clump. The results showed that: (1) In the plant growth phase, the dose of NPK fertilizer and onion leaf litter had an effect on plant height and number of leaves. The dose of NPK fertilizer was 1.2 g/plant and onion leaf litter 100 g/plant (D2K2), at plant height gave the best yield of 43.33 cm and the highest number of leaves was 47.00 strands. Meanwhile, the weight of the wet stove and the weight of the dry stove had a slight influence (tendency) which gave different results. On the weight of wet stover the dose of NPK fertilizer was 1.2 g/plant and onion leaf litter 100 g/plant (D2K2) with the highest yield of 14.67 grams and the dry stover weight dose of NPK fertilizer was 1.6 g/plant and leek litter red 150 g/plant (D3K3) with the highest average of 4.00 grams. (2) In harvest yields, the dose of NPK fertilizer was 0.8 g/plant and onion leaf litter 150 g/plant (D1K3) gave the best results for the number of tubers, namely 13.33 pieces, the highest wet tuber weight was 39 grams, and the highest dry tuber weight which is 29.33 grams. The total tuber weight per hectare is 3.3325 tons.
