The Effect of Ab mix Nutrient on Growth and Yield of Pak choi (Brassica chinensis L.) Plants under Hydroponic Wick System Condition

Abstract

This research was conducted to find out the effect of ab mix nutrient on growth and yield of Pak choi (Brassica chinensis L.) plants under hydroponic wick system condition. The research design used was non factorial Complete Randomized Design (CRD) with 5 levels of ab mix nutrient concentrations (0, 650, 1300, 1950, 2600 ppm), with 3 replications in each treatment. Each repetition consists of 6 plants, making a total 90 experimental units. The parameters observed were plant’s height, number of leaves, leaves area, fresh and dry weight, harvest index, leaf chlorophyll content, and root volume. Data was analyzed by using one way ANOVA, and DMRT as follow up. Research result shows that in hydroponic wick system ab mix nutrient gave very significant effect on pak choi (Brassica chinensis L.) parameters, such as: 1) plant’s height, 2) number of leaves, 3) leaves area, 4) dry weight 5) harvest index, and significantly effect on 6) fresh weight. However, it did not gave significant effect on root volume. The best results for each parameters observed were: number of leaves was 18.78, leaves area was 47.32 cm2, fresh weight was 33.57 gr, dry weight was 2.40 gr and harvest index was 99.15%, all were obtained from ab mix 1950 ppm treatment. The best results for plant height parameter was 8.71 cm obtained from ab mix 2600 ppm treatment.
