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.

Abstract

ABSTRACT VEGETATIVE GROWTH OF BROWN MIDRIB (BMR) SORGHUM ON THE DIFFERENT LEVELS SHADE OG SHADE AND POPULATIONS DENSITY. The present study was conducted to determine the effect of shading area and plant population density and their interaction on vegetative growth of Brown Midrib (BMR) Sorghum. A Completely Randomized Design (CRD) in a Factorial arrangement with 2 factors of nitrogen level and shading area, as follows: factor A = shading area of A1 = no shading area (0%), and N2 = shading area; whereas factor B = plant population density of B1 = 4 plants, B2 = 6 plants, B3 = 8 plants, and B4 = 10 plants. Variables measured were: leaves number, plant height, and the correlation between leaves number and plant population density. Research results showed that plant height in open area (no shading) was about 86.33 cm and significantly higher (P < 0.05) compared to other treatments. Leaves number in open area was about 7.55 sheats and significantly higher (P < 0.05) compared to other treatments. It can be concluded that shading positively decreased or retarded Brown Midrib (BMR) Sorghum growth as indicated by lower plant heights in shading area. In a limited daylight, plants needs an adaptation period to fulfill their needs for photosyntesis processes.   Key words: brown midrib (BMR) sorghum, growth, population density, shading

Abstract

EFFECT OF BOKASHI FERTILIZER LEVEL CHICKEN MANURE ON THE GROWHTH OF BROWN MID RIB (BMR) SORGHUM. The purpose of the present research was to determine effect of bokashi fertilizer level chicken manure on the growhth of brown mid rib (bmr) sorghum. The research was used in a completely randomized design arrangement, with 4 treatments and 7 replications. Treatments were formulated as follow : b1 = 0 g/polybag, b2 = 200 g/polybag, b3 = 400 g/polybag, b4 = 800 g/polybag. Parameters measured were : plant height, number of leaves length of leaves. Research result showed that,  bokashi fertilizer of chicken manure gave a significant different (p<0,05) on plant height, number of leaves leaves length of brown mid rib sorghum. Based on the research result, it can be concluded that, the utilization  of bokashi fertilizer level chicken manure with 200 g/polybag, enough to support  the growth of plant height, number of leaves and leaves length of brown mid rib sorghum.Keywords : Bokashi Fertilizer Level Chicken Manure, Brown Mid Rib Sorghum, Growth.
