The effect of organic fertilizers and inorganic fertilizer on mustard growth in Bahway village, Balik Bukit district, West Lampung regency

Abstract

Soil fertility is the relationship between the physical, chemical and biological properties needed by plants to grow and develop. The land used as a medium for growing mustard greens is taken from Bahway Village. The soil is treated with organic and inorganic fertilizers to test its fertility. The data analysis used was one way ANOVA and the least significant difference test and a randomized block design with three treatments and two replications. The treatments were: P1=100% organic fertilizer, P2=100% inorganic fertilizer, P3=50% organic fertilizer + 50% inorganic fertilizer and control. Based on the research results, it is known that the type of soil texture in P1 and P2 has a clay-sand texture, while P3 and C have a sandy loam texture. In terms of chemical properties, the pH at P1, P2, P3 and C are 5.53, 5.79, 5.50 and 6.20. For available P values, P1 = 188.31 ppm, P2 = 7.44 ppm, P3 = 113.62 ppm, and C = 2.48. Availability of Cation Exchange Capacity P1 = 22.56me/100g, P2 = 21.80me/100g, P3 = 23.19me/100g, and C = 23.75me/100g. From these results, what showed that the growth of mustard plants increased was the P3 treatment.
