Organic Kang Kong Production by Using Zeolite

Abstract

Study on organic kang kong production by using zeolite at the Horticultural Practice Station, Faculty of Agricultural Technology, Songkhla Rajabhat University, Songkhla campus, Muang district, Songkhla province in July, 2016. The experimental design was randomized completely block design (RCBD) with 4 replications in 5 treatments; 1) No zeolite applied as control, 2) zeolite at rate of 250 kg/rai, 3) zeolite at rate of 500 kg/rai, 4) zeolite at rate of 750 kg/rai, and 5) zeolite at rate of 1,000 kg/rai. The results showed that kang kong growing by using zeolite at rate of 1,000 kg/rai had high stem height (14.10), stem diameter (5.29 mm), number of leaves (10.47 leaves/plant), leave length (14.37 cm), and yield per plot (8.97 kg/rai) which was not significantly different (P≤0.05) with zeolite at rates of 250, 500 and 750 kg/rai while organic kang kong growing had lower growth and yield than other treatments.
