Abstract

      Potassium is a mineral nutrient that affects the growth, development, yield and quality of citrus in general and pummelo in particular. Lack of potassium in a short time would slow down the fruit growth resulting in small, rough fruits and poor fruit quality. To determine the appropriate potassium level and to establish the protocol for Dien pummelo integrated farming, the experiment was conducted in two years, 2013 and 2014. The results showed that application of 1.5 kg K2O combined with 50 kg of manure + 0.7 kg N + 0.5 kg P2O5 + 1 kg powder lime for each tree gave the best fruit quality, high fruit set, high yield and quality.
