on wheat growth and productivity at different elevation of Western Pamir |
In article the experimental information on the influence of presowing UV-irradiation of seeds on wheat growth and productivity at different elevation of Western Pamir are provided. It suggests that in wheat plants in Khorog conditions under the influence UV-irradiation of dry seeds, the growth of plants main stem and productivity are increased, however in Jelondeh stаtionаry conditions these parameters increased in control plants. |

In article the results of study on the influence of soil drought on the physiological parameters of some varieties of the L. are presented. It has been established that soil drought has a negative effect on plant growth, inhibits growth processes, and prevents the formation of fruits, because catches plants at the beginning of seed filling and causes great harm. |

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. |

Скачать | M.K.Gulov | 36-40 | 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. |

of the Western Pamirs |
The article presents the first study of the morphobiological features of Large short-stemmed apple tree MM-106 in stationary conditions of the Varchushdasht nursery of the high-mountain fruit laboratory of the Кh.Yusufbekov Pamir Biology Institute. There has been shown biological compatibility of cross-linked varieties and of non-native apples varieties in large short-stemmed apple tree MM-106 in the conditions of the Western Pamirs. |

Скачать | S.H.Rakhmatov | 54-59 | 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. |

The article describes the development of schemes for prevention and treatment. using probiotic drugs for salmonellosis of chickens - broilers. The use of probiotic drugs prevents the growth and reproduction of pathogenic and opportunistic microflora. the use of an antibacterial drug against the background of the use of probiotic drugs increases the therapeutic efficiency up to 80%. while when using only one antibiotic its therapeutic effect is 57%. The probiotics Monosporin. Prolam and Bacell prevent the incidence of salmonellosis in broiler chickens by 66.7%. |

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. |
