Features of the variety, plant density and fertilization on cotton productivity
The results obtained indicate that the development of a cotton variety reacts different to plant densities and nutritional levels. As the planting density increases to 130 thousand per I hectare with a simultaneous increase in fertilizer rates to N, Р, К kg/ha, the yield of cotton with the limiting type of branching, the early ripening varieties «Sorbon» and «Sugdien-2» increases to 55.8 and 47.8 c/ha respectively.

Ключевые слова: cotton; varieties; density of plants; fertilizers; harvest.

Influence of high temperature to productivity of potatoes summer planting
The article presents the results of a study of the effect of air temperature on the productivity of potato varieties during the summer planting period. It should be noted that in the conditions of the Khuroson region, when planting potato varieties on August 1, on average, there is in such economically valuable traits of potatoes will be the number of tubers (7.31 pcs./plant), the mass of one tuber (58.6 g), sample productivity (428.3 g/plant), total mass (673.2 g/plant) of potato. For summer planting and obtaining a high yield of potatoes in the conditions of southern Tajikistan, it is possible to recommend varieties Tajikistan (K), F(Nilufar x clone №2) and clone №73, which provide 24-28 t/ha of yield.

Ключевые слова: potatoes; summer planting time; variety samples; hot climate; air temperature; productivity; yield; Tajikistan.

Reasons for shelling fruits of vastern prime and measures of its prevention in the conditions of the Gissar valley
In article the results of studies of one of the reasons for the shedding of eastern persimmon fruits presented. The research results showed that with the same rate of fertilizers, the presence of pollinators and with a sufficient rate and amount of irrigation, the percentage of shedding of fruits was 8-15%, due to lack of irrigation (moisture) - 50-70%, and in conditions of excess irrigation, this figure reached 30-50%. The dependence of the percentage of eastern persimmon fruit shedding on the water regime, excess and lack of irrigation in gardens, as well as climate warming has been established.

Ключевые слова: oriental persimmon; shedding of fruits; watering; fertilizers.

Dynamics of lemon drying in different zones of Tajikistan
In this article the data on the study of the harmfulness and dynamics of drying out of lemon plants are presented. It has been established that the harmfulness of the disease significantly and negatively affects the growth and development of plants and, especially, the yield, quantity and quality of the crop. A survey of lemon plantations in the farm of N.Karabaev showed that the average number of fruits per one healthy plant is 232.5 pieces, and per one sick plant - 89.1 pieces, the yield loss was 61.7%. Observations have shown that the dynamics of the disease is influenced by environmental conditions.

Ключевые слова: lemon; disease; pathogen; damage; harmfulness; dynamics; growth and development; harvest.
