The Efficiency of the Potting Soil from Each Type of Organic Materail on Chemical Properties Growth and Yield of Red Batevia Salad

Abstract

This research aimed to study the efficiency of the potting soil from each type of organic materail on chemical properties growth and yield of Red Batevia Salad. The experimental as Completely Randomized Design : CRD, There were seven treatments of soil, including type 1 (soil, coconut husk, rice husk biochar, and goat manure with 2:1:0.5:1 proportion), type 2 (soil, coconut husk, rice husk biochar, and cattle manure with 2:1:0.5:1), type 3 (soil, coconut husk, rice husk biochar, and chicken compost with 2:1:0.5:1), type 4 (soil, coconut husk, rice husk biochar, and silk worm fertilizer with 2:1:0.5:0.5 ), type 5(soil, coconut husk, rice husk biochar, and vermicompost with 2:1:0.5:0.5, type 6 (soil, coconut husk, rice husk biochar, and dry bamboo leaves with 2:1:0.5:1). and type 7 (commercial soil) As a result, a treatment with soil, coconut husk, biochar, and goat compost (2:1:0.5:1 ratio) showed the 2 times most effective chemical properties of nutrient contents (P, K, Ca and Mg) and the highest growth of the crop, in terms of canopy width (18.88 cm) , the number of leaves (14.50) , wet shoot (56.85 g) and root weights (2.80 g).
