Abstract

Organic fertilizers have an important role in the success of vegetable cultivation. Marine mud contains a lot of nutrients and organic matter, so it is useful for improving degraded soils in the short term and a source of nitrogen and minerals (especially Ca and Mg) in the long term. This study aimed to examine and explain the effect of doses of cow dung fertilizer and marine mud, for the growth and yield of spoon mustard (Brassica rapa L). This research was conducted at the Plastic House of the Faculty of Agriculture, Pattimura University, from June to August 2018. The experiment in this study was a factorial experiment in a completely randomized design with two factors. The first factor was sea mud from Tulehu Village (L) with 4 levels, namely: without sea mud (control), 100 g, 200 g and 300 g per kg of soil. The second factor was cow manure (K) with 4 levels, namely: without cow manure (control), 5 g, 10 g. and 15 g per kg of soil. The variables observed included plant height, leaf number, leaf area, plant biomass fresh weight, crown fresh and root fresh weight. Data were analyzed using Analysis of Variance (ANOVA) and further test using Duncan's test at 0.05 level. The results showed that the sea mud treatment had a very significant effect on the variables of plant height (3, 4 and 5 weeks after planting, WAP), leaf number (4 and 5 WAP), leaf area, plant biomass weight and plant crown weight, number of leaves (3 WAP) and root weight, but had no significant effect on plant height at age (1 and 2 WAP), and number of leaves (1 and 2 WAP). The treatment of cow dung fertilizer had a very significant effect on the variables of plant height (2, 4 and 5 WAP), number of leaves (3 and 5 WAP), plant biomass weight and plant crown weight, a significant effect on plant height (3 WAP), leaf number (4 WAP), but had no significant effect on plant height (1 WAP), leaf number (1 and 2 WAP), leaf area and root weight of plants. The interaction between the treatment of marine mud and cow manure gave a very significant effect on plant height (4 and 5 WAP), but there was no interaction on the other observation variables. Keywords:  cow manure, marine mud, ‘spoon’ mustard, Ultisol soil
