Abstract

Availability in the soil varies greatly, influenced by the interaction between the chemical properties of the soil and some other soil traits such as the physical and biological properties of the soil. An analysis of the chemical properties of the soil is vital to recognizing availability of nutrients for future crop cultivation. The purpose of this study is to know the chemical conditions of the ground after the harvest of the peanut plant after given the mushroom compost post fertilizer. The design of the experiment used in this study is a complete random design (ral) with a dose of mushroom post baglog fertilizer 6 and a degree of fertilizer recommendation 1 (as control). As for the treating cedar that is used is p1 = 100% recommendation fertilizer, p2 = 2 ton ha-1 fertilizer compost of the mushroom baglog, p4 = 4 tons of ha-1 fertilizer compost of the mushroom baglog, p5 = 6 tons of ha-1 Studies show a different dosage of fertilizer has a real impact on all the parameters observed.

Abstract

Red lettuce is one of the horticultural crops that has many benefits and can increase the economic income of farming families. Cultivation of red lettuce plants requires proper maintenance and fertilization to increase the yield of red lettuce plants. To complement nutrients, the addition of organic and NPK fertilizers is required. The purpose of this study is to determine the effect of cow manure and NPK fertilizers 16:16:16 on soil properties and the growth of red lettuce plants (Lactuca sativa Var. Acephala). The method used in this research is an experimental method with a Completely Randomized Design (CRD) experiment consisting of two factors, namely factor I is cow manure (K) and factor II is Pearl NPK fertilizer (16:16:16) (P). Each treatment was repeated 3 times so that a total of 27 experimental polybags were obtained. The treatment with cow manure 10 tons/ha has the best value of C-organic (3.55%) and porosity (56.76%). The highest weight of wet stems of red lettuce plants was obtained in the treatment of 300 kg/ha NPK fertilizer and 10 tons/ha cow manure at 35.14 grams.
