Seven single strains and a commercial mixture of Bradyrhizobium japonicum were evaluated in association with two early-maturing Canadian soybean (Glycine max (L.) Merrill) cultivars, Maple Presto and Maple Amber. Inoculated and uninoculated plants were grown in pails outdoors. Soil temperature at 15 cm depth was monitored throughout the experiment. At the V2, V3, R2 and R4 growth stages, whole plants were removed from the pails. Nodules were counted and weighed; roots and tops were separated, weighed and analyzed for total nitrogen. Bradyrhizobium japonicum strains 61A148, 61A196, 61A194 and 61A155 were similar in effectiveness, but superior to strains 61A124a, 61A118b, 61A101c and the commercial mixture in earliness of nodule formation, number and weight of nodules per plant, and in promoting greater root and top growth and plant nitrogen accumulation. There were indications that soil temperature may have affected nodulation. Maple Amber showed the greater potential for symbiotic nitrogen fixation. This cultivar supported earlier nodulation, had a greater number of nodules, accumulated more nitrogen in the tops and roots and had greater growth than Maple Presto.Key words: Soybean, Glycine max (L.)

The Relationship

The relationship between herbicide injury and soybean [Glycine max(L.) Merr. ‘Amsoy 71’] yield response was studied under weed free conditions at three locations. Reduced crop vigor at early growth stages was not an adequate indicator of yield response. Yield reduction was greater when soybean stand was reduced by herbicides than when stand was reduced to the same level by hand thinning. Yield response was a function of the degree and persistence of crop vigor reduction in a reduced stand of soybeans.

These sets of experiments were conducted at Faculty of Agriculture Sebelas Maret University and the Central Experiment Station of Agricultural Faculty, Sebelas Maret University at Jumantono, Karanganyar, Central Java. The experiments were conducted under greenhouse, laboratory and field condition for each year, while the duration of this research was for two years. The specific objectives of the experiments were: (i) to determine the changes of some morpho-physiological characteristics of water stress soybean and those of unstressed plants at different growth stages; (ii) to evaluate relationship between morpho-physiological traits associated with water stress resistance and yield of soybean. In this study consists some experiments, there are: (i) about response of some soybean cultivars to water stress in screen house and field condition; (ii) about germination response of some soybean cultivars in different concentration 0f PEG; (iii) a bout recovery survival and recovery of soybean seedlings after heat treatment. The plants were well watered before thetreatment. Based on the result of the experiments, the following conclusion could be made: (i) water stress reduced growth, yield and yield components 0 f a II soybean c ultivars used; (li) PEG induced water stress resulted in lower germination, shorter root and shoot length, and increase root-shoot ratio; (iii) the ability of plants to recovery after heat stress have low correlation with drought resistance in this experiment; (iv) the determination of root-shoot ratio in the seedling stage was shown to be suitable screening techniques used to study water stress resistance.© 200'3Jurusan Biologi FMIPA UNS SurakartaKey words: soybean (Glycine max L.), cultivars, water stress.

Natural Farming

Current study was conducted to evaluate the influence of organic and zero budget natural farming on growth and yield of Soybean (Glycine max. L) under mountainous conditions of Himachal Pradesh. During the experimental period the variety of Soybean (Palam Soya) was sowed with eight treatments and three replications. The treatments consist of T1 -FYM-10t/ha+Rhizobium,T2-Vermicompost-7.5t/ha+Rhizobium,T3- FYM- 5 t/ha + vermicompost -3.75 t/ha + Rhizobium-T4 -Natural farming (Ghanjivamrit+Jivamrit+Bijamrit), T5 -FYM-10t/ha + vermiwash -3 spray, T6 -Vermicompost- 10t/ha +vermiwash – 3 spray, T7- Ghanjivamrit-125 kg/ha and T8 – FYM -5t/ha + ghanjivamrit – 125kg/ha with Randomized Block Design (RBD). During the course of study significantly highest plant height (cm), number of leaves, number of branches at various growth stages, days taken to 50 percent flowering and maturity were influenced by vermicompost along with three sprays of vermiwash. The significantly highest biological yield (2409.09kg /ha), seed yield (825 kg/ ha) and yield attributes of Soybean crop were recorded in the treatment T6 –Vermicompost @ 10t/ha + 3 sprays of vermiwash during the experiment.

Β Carotene

We obtained a new hybrid soybean (Hybrid) by hybridizing β-carotene-enhanced soybean (BCE; Glycine max L.) containing the phytoene synthase-2A-carotene desaturase gene and wild-type soybean (Wild; Glycine soja). To investigate metabolic changes between variants, we performed metabolic profiling of leaves (three growth stages) and seeds. Multivariate analyses revealed significant metabolic differences between genotypes in seeds and leaves, with seeds showing accumulation of phytosterols, tocopherols, and carotenoids (BCE only), indicating co-induction of the methylerythritol 4-phosphate and mevalonic acid pathways. Additionally, Hybrid produced intermediate levels of carotenoids and high levels of amino acids. Principal component analysis revealed metabolic discrimination between growth stages of soybean leaves and identified differences in leaf groups according to different genotypes at 8, 12, and 16 weeks, with Wild showing higher levels of environmental stress-related compounds relative to BCE and Hybrid leaves. The metabolic profiling approach could be a useful tool to identify metabolic links in various soybean cultivars.
