In the Upper Midwest, corn (Zea mays L.) and soybean (Glycine max [L.] Merr.) dominate landscape, but only for six to seven months of year. Thus, opportunities exist establish crops that can utilize remainder growing season contribute overall farm profitability. One species interest is pennycress (Thlaspi arvense L.), a lack established agronomic best management practices barrier successful cro...

using crop simulation models is an efficient complement to experimental research. crop models can also be helpful with respect to decision-making in sustainable farming system. this study was done to estimate genetic coefficients and evaluate performanced dssat in prediction of development, growth and yield in wheat. data from various field experiments for four wheat cultivars koohdasht, shirou...

Knowledge of when critical crop stages occur and how the environment affects them should provide useful information for crop management decisions and crop production models. This research evaluated two sources of data for predicting dates of silking and physiological maturityof corn (Zea mays L.). Initial evaluations were conducted using data of an adapted corn hybrid grown on a Typic Agriaquol...

This study aimed to evaluate the fruit yield and the distribution of ‘Tommy Atkins’ mango root system under different irrigation regimes in the semiarid region of Bahia. The experimental design was completely randomized with five treatments and three replicates: 1 Irrigation supplying 100% of ETc in phases I, II and III; 2 Regulated deficit irrigation (RDI) supplying 50% of ETc in phase I (begi...

Abstract Assessing size at maturity for European lobster Homarus gammarus across the North East Atlantic remains a fundamental knowledge gap this commercially valuable fishery. This study first time collates existing data on physiological of female H. Atlantic, including new from Scotland, Wales, and Isle Man. Physiological estimates were undertaken using 1309 lobsters 11 locations standardized...

Seeds of bean (Phaseolus vulgaris cv. Vernel) were collected throughout their development on the plant and dried at 15 degrees C and 75% relative humidity to a final moisture content of about 16% (fresh weight basis) to determine whether the onset of tolerance to this drying condition was related to changes in soluble sugars or the activities of the main antioxidant enzymes, namely superoxide d...

Age-related declines in physiological performance have been documented in a wide variety of organisms. However, it is unknown whether related species age in a similar manner or whether physiological differences associated with aging differ widely among species. Previous work has shown that the desiccation resistance of Drosophila melanogaster decreases rapidly with age. Other Drosophila species...
