This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial inoculation of grain legumes improves crop yield and soil quality. Grain legumes such as soybean as requires host specific Brayrhizobium japonicum to enhance growth, nitrogen fixation, and grain yield. However, limited information exists on how commercial Bradyrhizobium inoculants affect symbiotic plant performance and yield of soybean, and as well as soil health in Ghana's cropping systems. A field study (2-yr) was conducted at CSIR-Savanna Agricultural Research Institute's experimental field at Nyankpala, Ghana to determine the impacts of Bradyrhizobium inoculants on; (1) growth, nodulation, nitrogen fixation, grain yield of soybean, and (2) soil biological and chemical properties. We also evaluated the commercial inoculants effects on the subsequent maize and soybean crops. The experiment was laid out as a split-plot design where the main plot consisted of tropical soybean (Glycine max crosses (TGX)) varieties; Jenguma (TGX1448-2E), Afayak (TGX1834-5E), and Songda (TGX 1445-3E). The subplot consisted of three commercial Bradyrhizobium japonicum inoculants with different strains, Biofix (USDA 110), NoduMax (USDA 110) and Legumefix (USDA 532c) plus an uninoculated control. Assessment was made on nodulation pattern, shoot biomass, nitrogen fixation, grain yield, and residual N balance. Bulk and rhizosphere soils were sampled and analyzed for soil pH, available soil N (NO3-N and NH4+-N) and P, and soil microbial community structure by phospholipids fatty acid (PLFA) analysis. Inoculants improved nodulation, shoot biomass, nitrogen fixation and grain yield of soybean. Greater responses were associated with NoduMax and Biofix. Inoculation increased grain yield by ~30 %. Commercial inoculants also increased microbial biomass, and available P and NH4+-N. Afayak outperformed the other soybean varieties for biomass dry matter, nodulation (nodule number) and grain yield. Afayak also stimulated greater microbial biomass and available P compared to Jenguma. Furthermore, enhance microbial biomass was found in the rhizosphere compared to the bulk soil due to soil enrichment with root exudate and commercial inoculants. In assessing, the previous year commercial inoculants effect on the subsequent soybean and maize crops, three (3) independent mineral N fertilizer rates (0, 50 and 100 kg N ha-1) were added to the soybean-maize rotation phase. Biofix yielded superior maize shoot dry matter and grain yield. Maize grain yield from previous commercial inoculants was equivalent to grain yield from 50 kg N ha-1mineral N fertilizer ). Thus inoculating soybean with commercial inoculants reduced mineral N nutrition for the subsequent maize crop by 50%. In the soybean-soybean phase, the previous Biofix and the uninoculated control produced significant soybean grain yield than the previous NoduMax. In conclusion, TGX soybean varieties exhibited superior performance when inoculated with commercial inoculants especially Biofix and NoduMax. However yearly inoculation of soybean is needed to sustain enhanced grain yield and soil quality in Northern Ghana.

This book was released on 1970 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of soil water suction and soil temperature on rates of transpiration, photosynthesis, respiration and nitrogen fixation of soybean (Glycine max. Merrill, var. Chippewa 64) seedlings was studied. A special apparatus was developed in which the soil water suction of several cells with soybeans growing in them could be maintained independently at a selected temperature. Transpiration was determined by a constant-water level device which recorded the amount of water used over a period of time. Photosynthesis and respiration were measured using an infra-red gas analyzer. The total nitrogen content of plants was measured by the micro-Kjeldahl method at the beginning and end of a ten-day experimental period. Leaf surface areas were determined with an air flow planimeter. In general with increasing soil temperature rates of transpiration, photosynthesis, and nitrogen fixation increased slowly at first and then rapidly until a certain optimum range was reached and decreased at higher temperatures. Maximum rates occurred around soil temperatures, of 30, 27 and 27°C, respectively. The rate of respiration also increased with increasing soil temperature until an optimum range around 27°C was reached and then dropped rapidly as the soil temperature further increased. Rates of photosynthesis, respiration, transpiration and N-fixation decreased steadily with increasing soil water suction. The decrease in the rate of these metabolic processes with increased soil water suction was attributed to effects of changes in viscosity and root cell permeability, stomatal movement and translocation of metabolic substrates. At low soil temperatures the dry matter accumulation seemed to be controlled by the water supply. At higher than optimum soil temperatures the dry dry matter accumulation was very sensitive-to temperature changes and less soil water dependent. When the nitrogen supply from the soil is limiting, the nitrogen fixation may possibly be a most important factor in the metabolic processes and thus the growth of leguminous plants. It is obvious that for such a plant, soil water availability, soil temperature and nodule rhyzobium organism-plant relationships are important.
