System which integrating forestry and agriculture is known by agroforestry. Utilizing of unproductive land below the trees will be more optimum. Sentang (Azadirachta excelsa Jack) is one of the plants that can be used in agroforestry system. The aim of this research was to know the effect of agroforestry toward tree dimension and production of some soybean varieties. Research design that was used in this research is split plot design that consisted of 2 factors and three repetitions. Planting pattern as a main plot is a the first factor, consisted of planting pattern of agroforestry (S1) and monoculture (S0). The second factor that was a submain plot is some varieties of soybean which consisted of variety of Grobogan, Anjasmoro, Tanggamus, and Wilis.The results shows that accretion mean of tree height, stem and crown diameter of Sentang in agroforestry plot are bigger than in monocultural plot. Lateral root in monocultural plot is deeper than in agroforestry plot. The difference of plant growth in each planting pattern of agroforestry is affected by interaction among plant component. Utilizing of some soybean varieties in agroforestry of sentang one year old did not result significant production than in monoculture pattern. In this research, variety Tanggamus and Wilis on monoculturural plot has better growth and production than variety of Grobogan and Anjasmoro.Key words: agroforestry, tree dimension, sentang (Azadirachta excelsa Jack), soybean, varieties.

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during Kharif-II season 2005 to investigate the effect of row spacing and cultivars on the growth and yield of soybean. Three soybean cultivars: (1) Bangladesh Soybean -4 (G- 2), (2) BARI soybean -5 (BS-5) and (3) Shohag (PB-1) and four row spacings, (1) 20 cm, (2) 30 cm, (3) 40 cm and (4) 50 cm were used in the experiment in a split-plot design with row spacing in the main plot and cultivars in the sub-plot. Seeds were sown on 26 July 2005 at specified rows maintaining 5 cm plant to plant distance. The highest seed yield was obtained from 20 cm spacing and yield decreased with increased spacing irrespective of cultivars. Among cultivars the highest yield was given by cultivar BS-5 which was followed by PB-1. It was concluded that the soybean cultivars BS-5 and PB-1 could be selected for sowing in Kharif-II season and should be planted at 20 cm apart rows for achieving higher yield.

A field experiment was conducted during rainy seasons of 2011 and 2012 at Udaipur to evaluate the effect of weed control and sulphur on yield and quality of soybean [Glycine max (L.) Merrill]. The twenty eight treatment combinations comprising 7 weed management treatments (weedy check, pendimethalin 1.0 kg ha-1 pre- emergence, quizalofop-ethyl 50 g ha-1 and imazethapyr 100 g ha-1 post-emergence at 15 DAS, pendimethalin, quizalofop-ethyl and imazethapyr followed by hoeing and weeding at 30 DAS) in main plot and 4 rates of sulphur application (00, 20, 40 and 60 kg ha1) in sub plot were laid out in split plot design with three replications. All weed control treatments reduced weed dry matter at harvest during both the years. Pendimethalin followed by hoeing and weeding at 30 DAS was significantly superior in reducing weed dry matter of broad-leaved, narrow-leaved and total weeds at harvest over rest of the treatments. All weed control treatments significantly enhanced straw and biological yield of soybean over weedy check. Pendimethalin followed by hoeing and weeding at 30 DAS produced significantly higher pooled seed (2168 kg ha-1), straw (3167 kg ha-1) and biological (5335 kg ha-1) yields compared to other treatments. Sulphur rates had no significant effect on weed dry matter at harvest. Across the years, increasing level of S application up to 40 kg ha-1 resulted in significantly increased straw yield, biological yield and harvest index of soybean. Increasing rate of sulphur application up to 40 kg ha-1 tended to significantly increase protein and oil yield.

Purpose of this research was to get the best planting pattern on Curcuma (Curcuma xanthorrhiza Roxb. Synm. Curcuma javanica) and soybean (Glycine max (L.) Merrill) related to plants production, land equivalent ratio (LER) and R/C ratio. This research used the randomized block design involving six treatments and four replications. The growth pattern and yield of curcuma were based on the following parameters: length of plant, number of leaf, broad of leaf, fresh and dry weight of leaves, curcuma root and rhizome, LER (land equivalent ratio) and R/C ratio within six months from December 2015 to June 2016. The treatment difference was based on the LSD5%. The result showed that curcuma planted one month earlier under narrow spacing and bigger soybean population (strip relay, T-K)) suggested a longer growth than any other plating patterns. On the contrary, curcuma planted one month earlier under wide spacing and fewer number of soybean plants (row relay, T-K) suggested a better growth than others and resulting in the highest curcuma yield, lower soybean yield, LER=1.09 dan R/C=2.36.

Soybean pod damage caused by N. viridula reached 61.37% of the total pods and 61.67% of the total seeds attacked. Efforts were made, namely the application of chemical insecticides made from active chlorpyrifos which can reduce the population of N. viridula to reach 57.4% and the insecticides made from deltamerin which are reducing the population by 51.6%. Control is needed that can reduce the negative effects caused by chemical insecticides, one of which is mechanical control. Mechanical control can be done one of them with augmentation and conservation tools. the research is by taking the eggs of N. viridula in the field and laying the eggs in an augmentation and conservation tool with several treatments of different filter cloth diameters, 0.1 mm; 0.3 mm; 0.2 mm; and 0.6 mm. Observations were made by looking at and counting the number of parasitoids that were able to pass through the filter cloth and those that did not pass through the filter cloth, followed by identification of the species of the parasitoid that was obtained. The results showed that the parasitoids were able to escape in all treatments but with varying amounts. The difference in number can be influenced by the presence of parasitoids in the field and the level of parasitoid parasitation. Likewise with Trichogramma sp also able to pass on all treatments. Therefore, the most suitable treatment is treatment with a 0.1 mm diameter filter cloth. The identified parasites were T. rowani and T. podisi

A Survey in West Java shows that Mindi (Melia azederach Linn.) is frequently found on the community forest lands as part of a mixed cropping system. These community forest lands have a potential to support food security. Soybean is an important food crop as source of protein in Indonesian. This study aimed to observe the growth of Mindi and soybean in an agroforestry system. This study used a split plot design which consists of two factors. The main factors was Mindi which planted using shade and without shade and the second factors are soybean variety (Argomulyo, Anjasmoro, Grobogan, and Wilis) using four replication. The results showed that differences of Mindi cropping method did not significantly affect the Mindi growth (height and diameter) which has been observed for three months. Wilis had the highest survival rate than others varieties. Both factor shade and varieties giving a very significant effect on the kedelai height at the 3-7 MST age. In addition, it's also very significantly affected the number of leaves trifoleat at the age of 3, 4, and 5 MST. Soybean production in Mindi agroforestry system gaves the higher yield than monoculture system at three months age.Key words: Agroforestry, mindi, soybeans, shade, variety.

For centuries soy bean has been an appreciated legume in most Asian countries. There are two types of cropped soy bean, the vegetable type and the grain type. The difference between them is defined by the time of harvest. Vegetable soy bean is harvested between R6 and R7 growth stages, when the pod is still green and full at about 80% of the total weight. It is a nutritious plant with an appreciable content of protein, minerals and vitamins. Although it is best known in East Asia, vegetable soy bean is being increasingly incorporated in diets in North American countries and there is growing interest in some African countries. Many breeding programmes are being conducted to develop plants that mature early and produce larger and greener pods with good appearance and taste. Cooking usually consists of plunging the fresh pods into boiling salted/seasoned water and simmering them until tender. Different forcing and processing methods are employed to maintain production and availability throughout the year. Vegetable soy bean is transported either attached to or detached from the plant. The price of imported fresh vegetable soy bean has usually been low because the crop suffers in transport and there are few facilities for proper storage.

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.
