Abstract

Avocado is a multifunctional plant that can be utilized in all parts. The growth of avocado and its yield can be achieved by fulfilling requirements for the growth and maintenance of the plant well. Planting on dry land requires the addition of organic fertilizer and optimal water requirements to increase organic matter content and plant fertility. This research aims to obtain the optimal dosage of compost and watering intervals for the growth of avocado (Persea americana). The research was carried out in the Greenhouse Faculty of Agriculture, Universitas Sumatera Utara. This research used a factorial completely randomized design (F-CRD) with the addition of compost fertilizer doses (K0:0 kg, K1:0.5kg. K2: 1 kg. K3: 1.5 kg and K4: 2 kg) and watering intervals (A1: once a day. A2: once every three days. A3: once every five days and A4: once every seven days) with parameters of observation of height, diameter, top fresh weight, root fresh weight, top dry weight and root dry weight. The results showed that the interaction of compost and watering intervals significantly affected the height and diameter increase, root fresh weight, and root dry weight of avocado plants. The interaction of giving 1.5 kg of compost and watering intervals every day had the best effect on the growth and quality of avocado seedlings

牛油果（Persea americana）对不同剂量堆肥和浇水间隔的反应

牛油果是一种多功能植物，可以在各个部分加以利用。牛油果的生长和产量可以通过满足植物生长和养护的要求来实现。在旱地种植需要添加有机肥料和满足最佳的水分需求，以增加有机质含量和植物肥力。本研究旨在获得牛油果（Persea americana）生长所需的最佳堆肥用量和浇水间隔。研究在乌塔拉苏门答腊大学（Universitas Sumatera Utara）农学院温室内进行。该研究采用因子完全随机设计（F-CRD），添加堆肥剂量（K0:0 千克、K1:0.5 千克、K2: 1 千克、K3: 1.5 千克和 K4: 2 千克）和浇水间隔（A1: 每天一次、A2: 每三天一次、A3: 每三天一次、A4: 每三天一次）。A2：三天一次。A3：每五天一次，A4：每七天一次），观察参数包括高度、直径、顶部鲜重、根部鲜重、顶部干重和根部干重。结果表明，堆肥和浇水间隔的交互作用对牛油果植株的高度和直径增加、根鲜重和根干重有显著影响。每天施用 1.5 千克堆肥和浇水间隔的交互作用对牛油果幼苗的生长和质量影响最大。
