Abstract: The growth, development and productivity of the pea plant are closely linked to environmental factors. Therefore, in the cultivation of peas, it is important to ensure adequate environmental factors in the selection of varieties. The use of mineral fertilizers, especially nitrogen fertilizers, in the cultivation of peas on irrigated lands provides an increase in the composition of the crop. In this case, the number of legumes in the plant, the number of grains in the legume and other indicators are positive in plants fed with an optimal nitrogen regime, and an increase in the amount of nitrogen used leads to a decrease in these indicators. Nitrogen fertilizers are important in crop nutrition, and crop yields depend on the amount and duration of fertilizer used. It is important to study the effect of different amounts of nitrogen fertilizers on the yield of pea varieties in the conditions of irrigated grasslands.

Abstract: This paper reviews taxonomy, importance and diseases of pepper plants belonging to Capsicum genus. Five species of the genus are domesticated, Capsicum annuum being the most cultivated species followed by C. chinense and C. frutescens while C. baccatum and C. pubescens are grown in limited areas of some regions.
Previously the authors of the current paper have found that deadly crown rot of both sweet and hot peppers caused by Fusarium oxysporum (supposedly f. sp. radici-capsici) occurred widely in six districts of Uzbekistan.
