Production of Organic Fertilizer from Salted Egg Factory Waste and Waste Materials in Community to Grow Choy (Brassica chinensis)
Main Article Content
Abstract
The study aims to study the effects of organic fertilizers on growth and quality of choy. The planning experiment was a randomized complete block design (RCBD) with 3 replications and 6 treatments as follow: 1) egg shell + salted egg shell 2) egg shell + salted egg shell + salted egg white 3) egg shell + salted egg shell + cow dung 4) egg shell + salted egg shell + organic waste 5) chemical fertilizer 15-15-15 and 6) control unit. The results showed that the treatment with egg shell + salted egg shell + cow dung was the most growing suitable for choy. Choy resulted from this treatment had the height of 28.17±2.02 cm, the number of leaves of 6.67±1.53 leaves/plant, the leave length of 13.50±1.00 cm, the leave width 8.23±2.04 cm, the root length of 9.00±2.00 cm, the fresh weight of 11.62±2.00 g and the dry weight of 1.23±0.47 g.
