Pengaruh Pemberian Pupuk Kandang dan Eco Enzyme terhadap Pertumbuhan Bibit Alpukat (Persea americana Mill.) di Lahan Marginal Labuhanbatu Selatan

Abstract

Marginal land is dry land that has limited nutrient content and low productivity. The addition of organic fertilizers can improve the physical properties and fertility of the soil. That way marginal land can be utilized. The Avocado plant (Persea americana Mill.) is one of the beneficial plants to grow. Avocado is a plant that can produce fruit that has a high selling value and has several benefits. The purpose of this study was to determine the effect of applying manure and eco enzymes on the growth of Avocado seedlings (Persea americana Mill.) on marginal soils. This research was carried out at the Aek Raso Nature Park (Elephant Training Center) Aek Raso Village, Torgamba District, Labuhan Regency. This research was conducted from July to October 2022. Using a Factorial Complete Randomized Design with 2 factors, namely manure doses (0 gr, 500 gr, 1000 gr) and eco enzymes (0 ml, 10 ml, 20 ml, 30 ml) so that 48 treatments with 4 tests were obtained. The results showed that the interaction in the treatment of manure and eco enzymes on the parameters of plant height and the number of plant leaves and had an unreal effect on the parameters of plant diameter, fresh weight of the upper part of the plant, fresh weight of the lower part of the plant, dry weight of the upper part of the plant and dry weight of the lower part of the plant. The D2K1, D2K2 and D3K2 treatments gave optimal results on the growth of avocado seedlings (Persea americana Mill.) during 3 months of observation.
