“…For instance, plant establishment which translate into plants harvested have direct relation with crop production and yield [20,32]. A decrease in plant establishment will mean less competition for soil nutrient leading to vigorous plant growth as corroborated by Cardoso et al [33] and Ozer [34].…”

Common bean (Phaseolus vulgaris L.) provides nutritional, economic and health benefits. Ghana has introduced the first four commercial varieties for adoption. Maintaining seed quality in storage is challenged in the humid regions due to high temperature and high relative humidity. The study determined the interactive effects of seed moisture content (MC) and packaging material on quality of seeds stored for 8 months and subsequent seed yield and yield related components. A 2x2 factorial in Randomized Complete Block Design (RCBD) was used, replicated three times. Seeds were dried to 8 and 11% MC, kept in polythene bags and plastic containers and stored for 8 months under ambient and cold conditions. There were no significant differences (p>0.05) for plant stand at two weeks after planting, days to first and fifty percent flowering, chlorophyll content, number of pods per plant, number of seeds per pod, and seed yield. Leaf area index of plants developed from seeds dried to 8% MC and packed in polythene bags were significantly higher than the other interaction effects. The lowest plant stand was observed in plants developed from seeds dried to 11% MC and packed in plastic containers. 1000SW of seeds dried to 11% MC and packaged in plastic containers were 32.77% higher than in seeds dried to 8% MC and packaged in plastic containers. The Ennepa common bean seeds can be dried to 11% MC and packaged in polythene bags and stored for 8 months without significant seed deterioration.

Response of Indian Dwarf Wheat and Persian Wheat to Sowing Density and Hydrothermal Conditions of the Growing Seasons

et al. 2022

The need for foods with high nutritional value has led to the rediscovery of ancient wheat species Triticum sphaerococcum and T. persicum as raw materials with valuable consumption properties, but their reintroduction requires assessment of their productivity under different agricultural practices. The field experiments were carried out for three years (2018–2020) to test the hypothesis that the sowing density of T. sphaerococcum and T. persicum (400, 500 and 600 no m−2) will affect their agronomic traits, yield and occurrence of diseases, but the response will depend on the hydrothermal conditions of the growing seasons. In this study, a significant correlation of the grain yield with the amount of precipitation in tillering, and from booting to the beginning of fruit development was demonstrated. The sowing density of T. sphaerococcum had an impact on the grain yield only under moderate drought stress during the growing season (2019), when the highest yield was obtained at a sowing density of 600 m−2. In 2019, the most favorable sowing density was also the highest for T. persicum. In the year with the lowest amount of rainfall during the growing season (2018), the yield of T. persicum was the highest in the lowest sowing density. At the shooting stage, a greater intensity of powdery mildew was observed on T. persicum, especially with higher sowing densities. Increasing the sowing density also increased the occurrence of root rot symptoms in both wheat species in the year that favored the occurrence of this disease (2018). It can be concluded that in the integrated low-input cultivation of T. sphaerococcum and T. persicum, it is justified to use a sowing density of 600 pcs. m−2, in an agroclimatic zone with moderate droughts during the growing season.

Seed vigor in performance of wheat plants: evidence of interaction with nitrogen

The use of high-quality seeds is an important factor in the crop production system. Its benefits to the performance of plants and possible interactions with other factors - such as nitrogen fertilization - could be better understood from a multivariate analysis perspective. With this approach, the objective of this work was to evaluate the impacts of wheat seed vigor and possible interactions with nitrogen fertilization on the performance of wheat plants. The data analyzed were obtained from the average results gathered through three experimental environments, located in the department of Alto Paraná, Paraguay. High-vigor seeds with provided a better plant stand and also a greater growth in the formed tillers stage. This category also provided plants with higher performance - a condition found for dry matter weight - in the booting, flowering and milk seed stages, in the presence and absence of nitrogen fertilization. The multivariate analysis showed that plants originating from high-vigor seeds that had not been fertilized with N showed a similar performance to that of low-vigor plants, but fertilized with N. High-vigor wheat seeds provide plants with superior performance.
