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

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.

Laboratory studies were conducted on mating, ovipositional rhythm, and fecundity of the southern green stink bug, Nezara viridula (L.) fed on immature fruits of privet, Ligustrum lucidum Thunb. and soybean, Glycine max (L.) Merrill. A greater number of pairs were observed mating on privet (27 to 37 %) than on soybean (22 to 23 %). The preoviposition period was significantly shorter when females fed on privet (15.5 days) than when they fed on soybean (23.9 days). The intervals of time between the first four ovipositions, and between the 1st and the 4th oviposition were shorter on privet than on soybean (range of 1.9 to 3.3 days less on the former food). Greater percentage of females N. viridula oviposited and showed greater fecundity on privet than on soybean. On privet, the oviposition rhythm peaked at days 11 and 17; however, no peaks on oviposition were observed on soybean.

Estudos a campo e em gaiolas de campo foram realizados com o objetivo de verificar o parasitismo por Telenomus podisi Ashmead, em relação aos percevejos-pragas na cultura da soja (Glycine max (L.) Merrill). Os ensaios foram conduzidos em duas lavouras de soja na safra 1996/97, semeadas com as cultivares BR-48 e BR-37 na área experimental da Embrapa Soja, em Londrina, PR. Euschistus heros (Fabricius), Piezodorus guildinii (Westwood) e Nezara viridula (Linnaeus) foram as espécies de percevejos de maior ocorrência na cultura; a maior densidade populacional ocorreu no final do ciclo (5,3, 3,3, 3,6 - campo 1 e 5,2, 14,5, 7,5 percevejos / 2 m - campo 2, respectivamente). O parasitóide T. podisi, demonstrou, nas duas lavouras, maior ocorrência na população de E. heros, com parasitismo crescente no campo 1, alcançando 100% no final do ciclo da cultura, e ocorrendo em índice superior a 80% durante todo período amostral, no Campo 2. Nos testes em gaiolas de campo, a média de parasitismo obtida em ovos de E. heros em população isolada do hospedeiro, foi estatisticamente igual, quando comparada com ovos desse mesmo percevejo, em gaiolas com população mista, contendo as três principais espécies (31,7 ± 7,51 e 20,1 ± 6,67, respectivamente). Os ovos de P. guildinii e N. viridula, entretanto, foram sempre mais parasitados quando coletados em gaiolas com população mista. A presença do hospedeiro preferencial favoreceu o aumento no parasitismo dos ovos por T. podisi nas demais espécies de percevejos estudadas.

Time Of Harvest

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.

Four different tillage systems were compared in soybean [ Glycine max (L.) Merr.] production on one experimental field (chernozem) located in the Baranya region of northeastern Croatia in 2002 and 2003. The dry conditions experienced in 2003 exacerbated the negative effects of no-tillage on soybean yield. The 2-year average yield of soybean was significantly lower under no-tillage (NT) than in the conventional tillage (CT), soil loosening (SL) and disc harrowing (DH) treatments. The soybean oil and protein contents were very similar in all the tillage systems over the 2-year average. Soybean crude fibre (%) was affected by the main effect of tillage. Averaged over 2 years the crude fibre (%) of soybean grain was greater under NT than in the CT, DH and SL treatments. The ash (%) generally increased as tillage declined.

Glycine Max L

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.
