Rice Straw Biochar Application and its Impact on Yield of Some Faba Bean Varieties in Sandy Soil.

<b>Background and Objective:</b> Biological fertilization in the development of agriculture became one new strategy in the increased production of field crops to decrease the costs of production input and environmental pollution. This study focused on the influence of biochar fertilization on the productivity of faba bean varieties under sandy soils. <b>Materials and Methods:</b> Appreciation of the yield and its components, in addition to measurement of grain protein content as well as carbohydrates (%) of faba bean. <b>Results:</b> The data obtained indicated that the biochar amendment affects plant production at different rates, where the best yield obtained is 90 kg fed¹. The grain yield increase is significant for the variety's types where, Mariout-2, followed by Nubaria-3 followed by Giza-716 for the addition of 90 kg fed¹ of biochar as referenced by the non-conditioning treatment. Likewise, the protein content was highest in the Mariout-2 variety, followed by Nubaria-3 variety and Giza-716 variety for the addition. This improvement may be regarded to the impact of biochar on the physic-chemical characteristics for the soils, in addition to the biological characteristics. Furthermore, the biochar itself add nutrient to the soil after decomposition. The best improvement happens by the long-term cropping for a long period could be reached up to years. <b>Conclusion:</b> The conclusion that plant growth was better at a high rate (90 kg fed¹) but the economy of this rate may be questioned, under the condition of the study. However, the validation for different soils may vary with different rates, which needs more research. Also, it is recommended to use Mariout-2 cultivars for their high production under these conditions.

Effect of Foliar Application of Yeast and Algae on Yield and Quality of Soybean in Newly Soils.

BACKGROUND AND OBJECTIVE: Using the foliar application in development agriculture became a new strategy in the production system to decrease the cost of nutrition. This study amid to investigate the effect of yeast and algae on yield and quality of soybean under fertigation in newly soils at Wadi El-Natroun, El-Behaira Governorate, Egypt, during the two seasons 2018 and 2019. MATERIALS AND METHODS: The experimental design was a split-plot design in a randomized complete block arrangement with three replications. Yeast and algae were allocated to the main plots, while rates treatments were distributed at random in the sub-plots and control treatment foliar water. RESULTS: The results showed that either the foliar application with algae and yeast stimulates many growth aspects individually, such as plant length, number of seeds/plant and seed weight/plant compared to the control treatment. In addition, foliar spraying with algae at 8 g L-1 increased NPK content, crude protein content and total carbohydrate in seed. CONCLUSION: This study concluded that the foliar application influences at algae have provided high yields and chemical constituents under fertigation in sandy soil.
