Abstract
The purpose of this study was to examine the effect of applying manure and NPK fertilizer with the use of optimal fertilizer doses on odot grass. The materials used in this study were 720 stems of grass cuttings, 270 kg of manure, 2.5 kg of NPK fertilizer. The method used is factorial pattern experiments with random group designs. The first factor is manure consisting of K0 fertilizer: 0 kg / 5m2 fertilizer, K1 fertilizer: 7.5 kg / 5m2 fertilizer, K2 fertilizer: 15 kg / 5m2 fertilizer and the second factor is NPK (M) fertilizer consisting of M0 fertilizer: NPK 0 g / 5m2, M1: NPK Fertilizer 37.5 g / 5m2, M2: NPK Fertilizer 75 g / 5m2 and M3: NPK Fertilizer 112.5 g / 5m2. The measured variable is the Fresh Production and the Ratio of Leaves and Stems from the third Denudation. The average value of fresh production results obtained in each treatment up and down K0M0 = 6.71 ± 0.112. K0M1 = 6.87 ± 0.104, K0M2 = 6.82 ± 0.042, K0M3 = 8.55 ± 0.192, K1M0 = 7.33 ± 0.440, K1M1 = 7.69 ± 0.421, K1M2 = 7.91 ± 0.170, K1M3 = 7.33 9.94 ± 1.30, K2M0 = 9.35 ± 0.280, K2M1 = 8.20 ± 0.410, K2M2 = 10.46 ± 0.142, K2M3 = 11.21 ± 0.205. The average value of the ratio of stem leaves. K0M0 = 3.65 ± 0.12. K0M1 = 3.85 ± 0.293, K0M2 = 4.22 ± 0.083, K0M3 = 4.60 ± 0.049, K1M0 = 3.63 ± 0.255, K1M1 = 4.75 ± 0.202, K1M2 = 5.27 ± 0.194, K1M3 = 0.63 5.43 ± 0.140, K2M0 = 5.67 ± 0.075, K2M1 = 5.64 ± 0.110, K2M2 = 5.54 ± 0.081, K2M3 = 7.11 ± 0.278 Results of the analysis of variance showed that the application of manure was significant (P<0,01) and NPK fertilizer application were also significant (P<0.05) in Fresh Production. The application of manure to the leaf stem ratio was also significant (P<0.05) and the application of NPK fertilizer was also significant (P<0.01). Results The interaction between manure and NPK has a very significant influence on fresh production and leaf stem ratio. The higher dose of manure and NPK will increase the fresh production and ratio of stem leaves Keywords: Fresh production, leaf leaf ratio, odot grass, manure, NPK
