Abstract

An experiment to know the effect of plant row and the defoliation of maize leave to the yield of maize, growth and the yield of peanut was conducted in peanut field, socah district, Bangkalan. A 2x4 factorial with three replications was arranged in split plot design.  The first factor was plant row of design, i.e. single and double row of plant. The second factor was the defoliation of maize leave, i.e. 0% (the control), 30%, 40% and 50% of the defoliation of maize leave. Result of the experiment indicated that the defoliation of maize leave at 40% and 50% reduced the yield 38,70% and 39,40% of dry weigth of plant, 6,80% and 15,10% of 100 seed weigth.  The interaction treatment only gave significant effect in the maize-ear dry weigth; defoliation of maize leave very reduce the maize-ear dry weigth, especially in the double-row of plant. Defoliation of maize leave effect growth, component of yield and yield of peanut.  The row plant design effect to the leave area, component of yield and yield except to weigth of 100 seed. The double row of plant compare to single row of plant have dry weigth of pod, sum of pod, sum of seed and dry weigth of seed plant significant.  Increment of defoliation of maize leave significant to increase sum of branch, plant dry weigth, sum of leave, pod dry weigth, sum of pod, sum and dry weigth of seed of plant. The defoliation of maize leave until 40% are the best to tolerance to possible to yield optimum, especially in the  double row of plant.

Abstract

White oyster mushroom (Pleurotus ostreatus) harvest tend to reduced because  of  nutrients decreasing in the  growth media.  An effort  to increase its  production    is by adding nutrients  into  the growth media. This research aims to determine the effect of  nutrition  on growth  and production of  white oyster mushrooms. The nutrients used in this study is monosodium glutamate (MSG) and old  coconut  water.      The research method  used was  Complete Randomized Design  (CRD)  analysis  of variance  with  orthogonal  contrasts.  The treatments tested is the addition of nutrients after 3 times the harvest consists of four levels: control  (without  giving  nutrient solution), the provision of  nutrient solution Monosodium  glutamate  (MSG) 0.4%,  30%  old  coconut  water  and  nutrient combination of  MSG and old coconut water.  The results show that the addition of nutrients was not significantly different to the parameters of the total fresh weight, total  weight, mean  stalk  length,  average  diameter of  the bodies  and  biological efficiency of fruit.   However, it  significantly different  to the  parameters of maximum  hood width  average  and  buds  appearance time.   Based on  these observations we can conclude that feeding monosodium glutamate, old  coconut  water   and  combination of nutrients  monosodium  glutamate  and  old  coconut water  significantly  affect to maximum hood width  average  and  buds  appearance time.    Nutrition  as well as  without being given nutrients (control) of  body fresh  weight.  Nutrition old coconut water is better  than Monosodium  glutamate to maximum hood width average.  Monosodium glutamate or old coconut water nutrition  is better  than the  combination of nutrients monosodium  glutamate  and old  coconut  water  to the  long  shoots  appear.  Nutrition  increase wet weight up to 1.89%.

Abstract

Coffee is the second priority and is nationally leading commodity aimed to increase export  as well as  to improve added values of national production in order to gain high compatibility in the international level. The development of coffee plantation in Indonesia focuses on the increased proportion of arabica coffee. The technology offered is to establish the superior characteristics of robusta coffee (lowland habitats) and that of arabica coffee (highland habitats) into a single crop named robbica cofffee. The idiotype of arabica crops has not been studied at the low and moderate altitude of land.            The study uses a randomized block design arranged at a split-plot, where two altitude act as the main-plot (10 m and 500 m above sea level) and ten genotypes of arabica coffee as the sub-plot (five genotypes of arabica and five genotypes of robbica), with three replicates and four crops for each experimental unit. The sample crops are located  at the centre of the plot (two crops for each experimental unit). Variables observed are plant height (cm), stem diameter (mm), are of a couple of leaf (cm2), weight of a couple of leaf (gram), the number of stomata, the level of leaf greeness, the content of leaf chlorophile (A and B), and nitrate reductase activity.            Result of variance analysis showed that genotypes significantly affect plant height, stem diameter, area of a couple of leaf, weight of a couple of leaf, and the number of stomata. The level of leaf greeness, and the number of chlorophile (A and B) show insignificant responses genotypes. The study conclude that the idiotype of arabica coffee, i.e. that is having a combination of robusta and arabica performs better than pure arabica, the habitat of moderate altitude is more favourable than that lowland, and the cultivation of arabica at the moderate altitude requires a modification of enviroment by plantibg the shade plant from leguminosae family.
