Book Synopsis Above and Belowground Drivers of Weed-soybean Competition in a Long-term Organic Cropping Systems Experiment by : Margaret G. Ball

This book was released on 2017 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased weed free production capacity and decreased weed-crop competition intensity could help explain apparent crop tolerance of weeds in organic systems. The weed community and soil environment are affected by management history and could influence weed-crop competition relationships. We investigated weed-soybean competition in four organic cropping systems: (i) High Fertility (HF), (ii) Low Fertility (LF), (iii) Enhanced Weed Management (EWM), and (iv) Reduced Tillage (RT). In our experiment, the RT system had greater weed-free soybean production capacity, greater soil health, but also greater weed abundance and diversity than the EWM system. Soil inorganic N, K, Ca, and respiration were positively related to weed-free soybean production capacity. Unexpectedly, we observed positive relationships between weed-soybean competition intensity and several soil nutrient and organic matter indicators. Our research highlights connections between management history and weed-crop competition in organic systems, which could inform integrated weed management strategies.

Book Synopsis Effects of Soil Moisture and Atmospheric Conditions on the Water Status of Soybean Plants (Glycine Max (L.) Merrill). by : Cleber Morais Guimares
Download or read book Effects of Soil Moisture and Atmospheric Conditions on the Water Status of Soybean Plants (Glycine Max (L.) Merrill). written by Cleber Morais Guimares and published by . This book was released on 1979 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted in the field to study the effects of soil moisture and atmospheric conditions on the water status of soybeans. Leaf diffusive resistance at midday, and leaf water potential early in the morning and at midday correlated with soil moisture and atmospheric parameters. The atmospheric parameters studied were: solar radiation, potential evapotranspiration, pan evaporation and maximum air temperature. In addition leaf temperatures were correlated with leaf diffusive resistance. Atmospheric conditions explained the variations of non-stressed plants better than in the stressed plants in 1977 were explained better than in 1978. Probably factors associated with limited volume of soil, and different soil structure inside the soil containers used in 1978 were the reason for those variations of results. The highest yields were obtained from plants not stressed during the entire season. Treatments A (water stress initiated during the flowering), B (water stress initiated during early pod formation), and C (water stress initiated during later pod filling) reduced A and the control were the same. However, the seeds on plants of treatments B and C were significantly smaller. Stress applied during the late pod filling stage produced the smallest seeds. Information obtained from this experiment illustrated two points: (1) the importance of studying plant water status under natural environmental conditions, and (2) water stress during late pod filling is more deleterious on soybean yield than water stress imposed at any other stage.

Available in PDF, EPUB and Kindle. Book excerpt: Increases in soybean productivity have been relatively small compared to other major economic crops. Wet-soil culture, a relatively new technique of growing soybeans under a high controlled water table, has increased soybean production potential under Australian conditions. Therefore, two field experiments during 1985 and 1986 seasons were conducted with U.S. adapted varieties at the Plant Science Research Center, Mississippi State University. The first study had twenty-four varieties from three different maturity groups tested in three soil moisture regimes: wet-soil culture + N, conventional irrigation and dry. The 1985 season showed low performance of soybean plants grown in wet-soil culture compared to conventional irrigation and dry grown beans. Thiswas due to the water table being higher than intended, which resulted in near flooding. Planting of flat beds contributed to this near flooding situation. By planting on elevated beds in 1986, the wet-soil culture outyielded the other two soil moisture regimes due to better water table control. The second study was a combination of two varieties, five rates of N and two times of initiating wet-soil culture. The varieties were Tracy-M and Centennial (Leflore in 1986). Nitrogen was surface applied as urea at five rates. Time of initiating wet-soil culture was V3 and V8 growth stages. The same problem of near flooding occurred in this experiment, as evidenced by stem splitting. This morphological change was not present in 1986. Seed yield was slightly (...).
