Effect of foliar application rates of Calcium and Boron on yield and yield attributes of soybean (Glycine max)

Foliar fertilizers of soybeans have been widely reported in many field trials. Although Calcium and Boron are essential nutrients for soybean, research results have shown that foliar application of nutrients has been contradictory. The objective of this study was to evaluate the soybean response by applying different foliar fertilizer rates Calcium and Boron on yield components and soybean yield applied at flowering...

Seed yield and agronomic performance of seven improved cowpea (Vigna unguiculata L.) varieties in Ghana

Cowpea is well adapted to environmental conditions that affect crop production such as drought, high temperatures and other biotic stresses compared with other crops. Notwithstanding, growth and development of many cowpea cultivars are affected by drought and high temperatures, especially during floral development. This is because cowpea cultivars tend to have narrow range of adaptation as cultivars developed for one...

Postharvest dehydration of Syrah grapes (Vitis vinifera L.) under controlled temperature conditions with real-time monitoring of mass loss

The partial dehydration of grapes after harvest aimed at winemaking has been shown to be a process that brings increased concentration of sugar and phenolic compounds in the must, which affects the quality of the wines produced. However, the works developed so far have studied the process for temperatures up to a maximum of 25°C and air velocity lower than 1 m.s-1. This study aimed to analyze the physical-chemical...

Supremacy of rice genotypes under aerobic condition for mitigating water scarcity and future climate change

The increase in water scarcity, now made the researchers to look for various ways to decrease water use in rice production and increase the water use efficiency. One of the approaches that lead to a considerable amount of savings in water use by rice is aerobic cultivation, which minimizes the methane emission also. In this light of view, an investigation was carried out to study the morpho-physiological traits and...

Stability analysis in Wheat: An application of additive main effects and multiplicative interaction

Genotype-environment interaction and stability performance were investigated on morphological, yield and yield attributing traits in three environments. The AMMI analysis showed that maturity, morphological, yield, and yield attributing traits were highly influenced by genotype, environment and genotype-environment (GE) interaction. Environment had the largest contribution to the total sum of squares indicating that the...
