EFFECT OF LEVEL BOKASHI CHICKEN MANURE AND PLANT POP­ULATION DENSITY ON VEGETATIVE GROWTH OF BROWN MIDRIB (BMR) SORGUM. The aims of this experiment was to study the interaction of bokashi chicken manure and plant population density on vegetative growth of sorghum Brown Midrib (BMR). Level bokashi were A1 = 0 G; A2 = 200 G; A3 = 400 G and A4 = 800 G/polybag interact with plant population density B1 = 2 plants; B2 = 4 plants and B3 = 6 plants/polybag. Treatments were arranged in a 4 x 3 factorial with 3 replications based on a Completely Randomized Design (CRD). Variable measured were leaf length of leaf, number of leafes and plant height. The results showed that the interaction of treatment had significant effect on leaf length (P<0.05), but did not have significant effect (P>0,05) on number of leafs and plant height. Each treatment gave significant different effect on these both variable (P<0.05). Based on this results can be concluded that to get optimal vegetative growth of sorghum BMR needs bokashi fertilizer by 400 G/polybag at density of 2 plants/polybag. Keywords: Bokashi level of chicken manure, plant population density level, growth sorghum, growth

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

RESPONS OF FORAGES COVER CROPS ON LEVEL OF ORGANIC FERTILIZER BOKASHI AND PLANT POPULATION DENSITY. The objectives of this research was to asses the interaction of bokashi levels and plant population density on vegetative growth of sorghum Brown Midrib (BMR) and Leucaena leucocephala legume trees. Level bokashi were LB1 = 0 G; LB2 = 200 G; LB3 = 400 G and LB4 = 800 G pot-1 interact with plant population density of KP1 = 2 plants; KP2 = 4 plants and KPB3 = 6 plants pot-1 of BMR, and for Lamtoro plant density were KP1= 1 plat, KP2= 2 plant, KP3= 3 plant and KP4 = 4 plant pot-1. Treatments were arranged in a 4 x 3 factorial with 3 replications based on a Completely Randomized Design. Variable measured were leaf length of leaf, number of leafes and plant height. The results showed that the interaction of both treatment had significant effect on leaf length (P<0.05), but did not have significant effect (P>0,05) on number of leafs and plant height of BMR. On the otherhand the optimum plant density was 3 plant per pot. Based on this results can be concluded that to get optimal vegetative growth of sorghum BMR needs bokashi fertilizer by 400 G/polybag at density of 2 plants/polybag, but up to 3 plant per pot for lamtoro.Keywords:Bokashi level of chicken manure, plant population density level, growth sorghum, growth.

Quality Weight

An experiment was carried out to study the effects of the following population densities cauliflowers (plants per ha): 20,833 (0.60 m x 0.80 m), 25,641 (0.60 m x 0.65 m), ....37.037 (0.60 m x 0.45 m) , 55.555 (.0.60 m x 0.30 m), and 111,111 (0,60 m x 0,15 m) ; variety Snow ball. It was concluded that the effects of plant population density are greater on curd quality (weight and size) than on production per ha. The best plant population density to produce cauliflowers curd for Brazil market is from 20,000 to 25,000 plants/ha while for mini-curd is above 55,000 plants/ha.

Abstract Development of ideal breeding and crop management strategies that can improve maize grain yield under tropical environments is crucial. In the temperate regions, such yield improvements were achieved through use of genotypes that adapt high plant population density stress. However, tropical germplasm has poor tolerance to high plant population density stress, and thus it should be improved by temperate maize. The aim of this study was to estimate the genetic gains and identify traits associated with such gains in stable and high yielding temperate x tropical hybrids under low and high plant population densities. A total of 200 hybrids derived from a line x tester mating design of tropical x temperate germplasm were developed. These hybrids were evaluated for grain yield and allied traits under varied plant population densities. High yielding and stable hybrids, such as 15XH214, 15XH215 and 15XH121 were resistant to lodging and had higher number of leaves above the cob. The high genetic gains of 26% and desirable stress tolerance indices of these hybrids made them better performers over check hybrids under high plant population density. At high plant population density yield was correlated to stem lodging and number of leaves above the cob. Future gains in grain yield of these hybrids derived from temperate x tropical maize germplasm can be achieved by exploiting indirect selection for resistance to stem lodging and increased number of leaves above the cob under high plant density conditions.
