Abstract

The study aims to determine the effect of providing various types of organic fertilizer on the growth of spinach on marginal soils. Held in the Faculty of Agriculture greenhouse for pot experiments. Soil analysis, manure and compost are done in the Laboratory. Research using the RAL method A = Control B = Chicken manure 30 tons / ha, C = Cow Manure 30 tons / ha, D = Pig manure 30 tons / ha, E = Goat Manure 30 tons / ha and F = Compost 30 tons / ha per treatment added with sand. The study was conducted with 3 replications obtained 18 experimental pots. The data obtained were analyzed by analysis of variance and if there was a real influence continued with the LSD test of 5%. The results showed, the provision of various types of organic fertilizer on marginal soils significantly affected the availability of nutrients needed by plants in the growth and production of spinach plants in this case plant height, number of leaves, fresh weight of plants.

Abstract

Research conducted in the field aims to obtain data and information about: 1). Organic carrot products; 2). The best combination of treatments for carrot production; and 3). Some physical properties of the soil are a result of treatment.  The things observed include the main data, namely: bulk density, moisture content, soil permeability and production of carrots and additional data, namely: organic C, N, P, K. and pH in soil and compost, soil texture, rainfall, temperature and altitude.  The research method is a 2-factor randomized block design with 3 replications. The first treatment is plastic mulch with two levels of treatment, namely: 1). Plants with plastic mulch (0) and 2). Plants without plastic mulch (1). The second treatment is compost with three levels of doses, namely: 1). 0 tons/ha; 2). 15 tons/ha; and 3). 30 tons/ha. The results showed that the use of plastic mulch and compost 15 tons/ha gave higher production, which was 2.93 kg perplot.
