Bioregulator and foliar calcium supplementation in soya (Glycine max L.)

Flower and pod abortions in large quantities are commonly observed in soybean plants. In normal conditions of crop cultivation, flower abortion is commonly above 60%. Among the strategies that may promote great flower and pod set in soybean, there is the use of plant growth regulators and foliar applications of calcium. Thus, this study aimed to evaluate the effects of different doses of plant growth regulator and the...

Influence of soil conservation practices on soil moisture and maize crop (Zea mays L.) productivity in Centre Benin

Soil quality constitutes a major factor for crops growth. This study aimed at determining the sustainable soil conservation practices that would increase maize growth as well as production and improve the soil moisture. Two experimental sites were chosen: Dan localized on Acrisol and Za- zounmè localized on ferralsol. Two cropping seasons were investigated: the long rain seasons of 2018 and 2019. The experimental...

Grain morphological characterization and protein content of sixty-eight local rice (Oryza sativa L) cultivars from Cameroon

Rice (Oryza sativa L.) cultivated in Cameroon is appreciated by consumers for its nutritive quality and good taste. Diversity of 68 local rice cultivars was investigated via grain morphology and protein content characterization. The size and shape of grains were determined and used with yield parameters to classify the cultivars and perform Principal Component Analysis (PCA). Total protein content and glutelin content...

Application technology of imidacloprid in wheat: Effects on Schizaphis graminum management and natural enemies

Wheat production is dependent on costly insecticides that generate social and environmental issues. The growing demand for a rate reduction of spray applications and increased spray efficiency make essential the research for more adequate crop management. Therefore, this study aimed to evaluate technologies of imidacloprid application on wheat aphid, Schizaphis graminum and its natural enemies, Chrysoperla externa and...
