O trabalho foi desenvolvido no município de Bossoroca, RS, em uma área experimental de 31,17 ha, subdividida em sete setores de aproximadamente 4,45 ha. Foram coletadas 25 plantas em cada um dos setores, sendo medidos os parâmetros de crescimento e desenvolvimento em períodos quinzenais, seguidos da determinação dos componentes de produção na colheita. O manejo de irrigação baseou-se em turno de rega estipulado pelo instrumento irrigâmetro, com mesma lâmina em todos os setores. Os pontos da área georreferenciada foram visualizados através do software ArcGIS 9.3, gerando mapas de produção. As médias de produção dos diferentes setores foram submetidas à análise de variância e a comparação de médias pelo teste de Tukey a 5% de probabilidade de erro. Concluiu-se que ocorreu variação na produtividade entre os setores, sendo que no setor 03 observou-se maior produção com 6713,25 kg ha-1 e o setor 05 a menor com 5248,05 kg ha-1. Palavras-chave: Glycine max, L.; manejo da água; componentes de produção.  NUNES, M.

The work was developed in Bossoroca city, RS, in an experimental area of 31.17 ha, subdivided into seven sectors of approximately 4.45 ha. In each sectors, 25 plants were collected, being measured growth parameters and developing of plants in fortnightly periods followed by determination of component production at harvest. The irrigation management was carried out with the irrigation schedule stipulated by Irrigameter instrument, with same sheet of water in all sectors. Points georeferenced area were visualized using ArcGIS 9.3 software, where maps production were generated. Average production of different sectors were subjected to analysis of variance and Tukey test at 5% probability. It was concluded that there was variation in production across sectors, where sector 03 had the highest production with 6713.25 kg ha-1 and the sector with the smallest 05 5248.05 kg ha-1. Keywords: Glycine max, L.; water management; production components.

Two experiments were conducted in the Savelugu-Nanton Municipality of the Northern Region of Ghana in 2012 and 2013 to assess the effect of N fertilizer on growth, N remobilization and grain yield of three local varieties of soybean (Glycine max [L] Merill). The experiments were a 3 x 4 factorial laid in Randomized Complete Block Design (RCBD) with four replications. Factor A was soybean varieties (Jenguma, Quarshie, Ahotor); Factor B was 0, 15, 30 and 45 kg N ha-1. The experimental fields were planted manually on the flat by drilling and later thinned to 2 plants hill-1 at 0.50 m × 0.10 m with a population of about 400 000 plants ha-1. Growth and yield parameters measured were plant height, nodule number plant-1, nodule dry weight plant-1, percent nodule effectiveness, number of pods plant-1, number of seeds pod-1, 100 seed weight, harvest index and grain yield. The results showed that the control recorded lower figures in all growth parameters. Nitrogen remobilization was also observed in all plots, which indicate that soybean needs greater levels of N during grain filling. Again, N remobilization and soybean yield were highest in the 45 kg N ha-1 treatment compared to the other treatments. However, considering the overall yields, farmers in the study area should be advised to adopt starter N fertilization of soybean for higher yields as the soils are highly degraded in soil fertility.

A pot experiment was conducted to evaluate the effects of zinc and vermicompost on the growth, yield and nutrient content of soybean (Glycine max L.) plant. The treatment variables were control (‒Zn and ‒VC), VC 5 ton/ha, Zn 1 kg/ha, Zn 2 kg/ha, Zn 3 kg/ha, Zn 1 kg/ha + VC 5 ton/ha, Zn 2 kg/ha + VC 5 ton/ha and Zn 3 kg/ha + VC 5 ton/ha. Application of zinc and vermicompost showed a significant effect on the growth parameters and macro- and micronutrients uptake by the plant. The highest average plant height (164 cm), leaf number (80 nos./plant), leaf area (3360 cm2/plant), fresh weight (49.03 gm/plant), dry weight (24.54 gm/plant), fruit length (9.4 cm), fruit number per plant (5 nos. /plant) were recorded for Zn 1 kg/ha + VC 5 ton/ha treatment while the lowest values were observed in control at harvest. Results of the growth parameters varied significantly (p ≤ 0.05) with time. It was observed that, the overall best growth performance was achieved in Zn 1 kg/ha + VC 5 ton/ha. Dhaka Univ. J. Biol.

Stem Development

The main stem development and the photosynthetic activity of leaves 2 to 9 were studied in soja (Glycine max (L.) Merr.) at the leaf blade extension and adult stages. A correlation between the different leaf growth parameters (rates, durations) and the phyllochrone has been demonstrated. That correlation varied with the age and rank of the leaf. Moreover, the existence of correlations between net photosynthesis on one hand and the rate of development and the leaf growth kinetics on the other hand reveals an interdependence between photosynthesis and morphogenesis.

In the present investigation, the contributions of two indigenous arbuscular mycorrhizal fungi (Glomus mosseae and Acaulospora laevis), along with Trichoderma viride and Bradyrhizobium japonicum on growth parameters of Soybean, Glycine max (L.) Merrill were investigated. The results obtained indicated the dependence of soybean on mycorrhizal symbiosis. The different growth parameters increased significantly after 120 days of inoculation in comparison to control. Among all the growth parameters studied, plant height (162±3.34), fresh shoot weight (31.26±1.45), dry shoot weight (3.52±0.05), fresh root weight (4.07±0.56), dry root weight (1.03±0.03), root length (49.0±4.47) and leaf area (32.58±1.70) were highest in the combination of G. mosseae + A. laevis + T. viride + B. japonicum but arbuscular mycorrhizal (AM) spore number (95.2±3.19) and percent mycorrhizal root colonization (93.26±3.96) were maximum in single inoculation of G. mosseae. Second most effective results were observed in the plants treated with G. mosseae alone. Thus the presence of arbuscular mycorrhizal fungi (AMF) and other bioinoculants in rhizosphere of soybean had positive effect on the different growth parameters.

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.
