PENGARUH MANAJEMEN LAHAN DAN PEMUPUKAN KOTORAN SAPI TERHADAP PERTUMBUHAN DAN HASIL PADI GOGO VARIETAS INPAGO 12

Abstract

The continuous use of inorganic fertilizers can cause new problems such as decreased soil fertility. On agricultural land, the problem of nutrients leaching in the soil often occurs which results in nutrients not being absorbed optimally by plants. This study aims to explain the effect of land management and vermicompost fertilization on the growth and yield of upland rice variety Inpago 12. This experiment used a factorial randomized block design. Factor 1 is land management which consists of two levels, namely: M1 = a common land management, M2 = Land Management with an Impermeable Layer. Factor 2 was vermicompost fertilization management which consisted of three levels, namely: recommended dose of inorganic fertilizer (F1), half the recommended dose of inorganic fertilizer and 2.5 kg/m2 of cow dung (F2), and organic fertilizer 5 kg/m2 of cow dung + 1 kg/m2 of Biochar (F3). The variables observed were the growth and yield variables of Inpago 12 rice. The data obtained were analyzed for variance (ANOVA) at the 5% level. If there is a significant effect, proceed with the 5% LSD test. The results showed that in the M1F1 treatment (common land management with recommended dose of inorganic fertilizer) gave the best response of growth and yield of Inpago 12 upland rice. Meanwhile, in a separate test, the common land management treatment gave higher growth and yield of upland rice of the Inpago 12 variety compared to land management using an impermeable layer. Based on the results of this study, it is suggested that the application of F2 treatment fertilizer (half the recommended dose of inorganic fertilizer + 2.5 kg/m2 cow dung) can be recommended to replace the use of recommended dose of inorganic fertilizer.
