The aim of this research is to obtain data and determine the effect of utilization cow manure mixed with EM4 on growth of  sorghum variety kawali. This study was conducted using a completely randomized design (CRD) which consists of 4 treatments and 5 replicates in each treatment. The treatments were divided into plots of the experimental unit without fertilizer (P0), the plot using organic fertilizer of 4 kg/6 m2 (P1), plot using organic fertilizer of 8 kg/6 m2 (P2), and plot using organic fertilizer of 12 kg/6 m2 (P3). The variables measured in this study were plant height, number of leaves and leaf width. The HSD test indicated that at high treatment plants showed that treatments between P3 and P0 and between P3 and P1 were highly significant. However, treatments between P3 and P2 showed no significant difference. In the treatments of advanced test HSD indicated also that number of leaves between P3 and P0 showed highly significant, but between P3 and P1, and between P3 and P2 showed no difference. In the treatment of wide leaves using HSD test showed that treatment between P3 and P0 was highly significant, but those between P3 and P1 and between P3 and P2 showed no difference. Statistical analysis showed that treatment using cattle feces bokashi as the organic fertilizer of 12 kg/ 6 m2 (P3) produced high significant influence on plant height, leaf number, and leaf width. Based on this research it can be concluded that cattle feces bokashi as the organic fertilizer up to 12 kg /plot of 6 m2 produced the best effect on plant height, leaf number, and leaf width of kawali sorghum variety.

Abstract

EFFECT OF SHADING AND NITROGEN LEVEL TO CHARACTER OF GROWTH  CORONIVA GRASS (Brachiaria humidicola).The Coroniva grass (Brachiaria humidicola) or Schweick was ruminant animal feed grass with high ability for land recovering, land erosion and high nutrient quality for ruminant animals. In the areas with high sun light and land nutrient availability,this grass was capable to increase carbon accumulation under top soil and contribute the nitrogen (N) as fixation result of Azotobacter microorganism. Under shading areas and lack of land nutrient availability, especially nitrogen, growth and production potentials had not been fully explored. The objective of this study was to evaluate the levels of shading areas and nitrogen fertilizer on growth traits, dried matter plant leaf canopy and ratio between plant canopy and plan root of Coroniva grass (Brachiaria humidicola). Treatments were divided into three levels of shading (0%, 40%, 70%) and nitrogen fertilizer levels of 0 kg, 50 kg and 100 kg ha-1. Treatments were applied using factorial design based on block randomized design. Results showed that interaction between shading area of 40% and N level of 100 kg ha-1 produced the highest numbers and length of stolon, while the highest numbers of propagating plant were found at interaction between shading area of 40% and N level of  50 kg ha-1. Therefore, it can be concluded that growth traits of Coroniva grass were determined by the factors of shading areas and nitrogen macro element. Key word: Coroniva grass, shading area, nitrogen, growth.
