World Journal of Agriculture and Soil Science The paper summarizes the results of studies of the role played by the plant leaf extracellular space in the regulation of mesophyll cells water exchange, photosynthesis and export of assimilates to consuming sink organs. When comparing different methods of assessing water exchange rates, the participation of the plasmalemma in the formation of the leaf water potential was shown. Using the in vivo method of extracting the contents of the apoplast, the dynamics of the exit and movement of labeled photosynthetic products through the extracellular space was traced. It was shown that there is a circulation of assimilates in the plant. As the sugars move downwards along the phloem, they partially escape into the extracellular space and are carried away upwards by the transpiration stream, where they re-enter the leaves that have completed growth and are re-exported. This creates a common pool of photosynthetic products, which serves ...

World Journal of Agriculture and Soil Science A significant part of the world’s fruticulture is rainfed managed. Olive, almond and vine are some of the perennial crops whose social and economic importance is huge throughout the Mediterranean basin and which mostly continue to be grown in rainfed conditions. Cover cropping is the most recommended soil management system in fruit growing. However, in rainfed managed orchards, soil tillage continues to dominate, and the use of herbicides is also widely used. In rainfed conditions there is a high risk of competition for water between herbaceous vegetation and trees, which makes difficult the widespread use of cover crops. However, there seem to be new clues to overcoming the problem, consisting of the use of less competitive plants, such as early-maturing self-reseeding annual legumes. These plants are able to protect the soil from erosion, sequester carbon and increase soil organic matter, fix nitrogen and promote the nutritional sta...

World Journal of Agriculture and Soil Science Crop performance is the results of genotypic expression modified by interaction with the environment. One of the environmental factors, that most widely limiting for the crop production is water. The deficit of water significantly limits the growth, development and yielding of crops. The paper presents a mini review of the own research results and the literature on the effect of water shortage on the rate of photosynthesis of forage grasses. A better understanding the physiological reactions of plants to water stress should improving irrigation efficiency, modifying plants for more efficient water use, and developing effective agriculture on dry area.

World Journal of Agriculture and Soil Science Countryside Stewardship (CS) has been England’s principal Agri-environment scheme providing financial incentives for farmers and land managers to look after the environment by undertaking a range of management options such as creating, restoring and improving habitats, reducing water pollution and keeping the character of the countryside. Aside from the benefits for biodiversity and ecosystem services many of the available management options under CS offer opportunities for mitigating the effects of climate change either by reducing greenhouse gas emissions or by increasing carbon sequestration. However, it can be a challenge to quantify the benefits (and burdens in some instances) due to the breadth of the scheme itself and the complexity of the factors involved such as the physical, chemical and biological processes, and spatial and temporal variability due to geographical and climatic factors.

World Journal of Agriculture and Soil Science Nitrogen (N) is one of the major determining nutrients for growth and development of cauliflower (Brassica oleracea L. var. botrytis). N deficiency in cauliflower field is becoming a major problem in Nepal. Soil application of appropriate amount of N can be an effective way to increase the qualitative and quantitative growth parameter of cauliflower. A field experiment was carried out in ultisols at Sundarbazar ward no.7 Taarkutar village of Lamjung district Nepal, during September 2017 to February 2018 to assess the response of five level of soil application of nitrogen (0 kgha-1, 80 kgha-1, 100 kgha-1, 120 kgha-1 and 140 kgha-1) on three genotypes of cauliflower (Kathmandu local, Snow mystique and Snow grace). The experiment was laid out in Randomized Complete Block Design consisting of 15 treatments with 3 replications.

World Journal of Agriculture and Soil Science Improving food security in Woliso woreda closely related with the elimination and reduction of poverty at woreda and individual level. Some of the rural household in Woliso woreda is suffer by food insecurity. Therefore, this study was investigated the determinants of food insecurity in the study area through using extended primary data.
