Description
The provisions to improve the efficiency of vineyards are the selection of varieties different by ripening, adapted to local conditions, as well as the use of a new generation of fertilizers. According to phenological observations and actual production period, the varieties of table grapes are divided into groups by ripeness – early and middle. According to the yield, there were emphasized the following varieties: in the early group – Cardinal (11,3 t/ha), Vostorg (Delight) (11,2 t/ha), Bogatyrskiy (10,9 t/ha); in the middle ripening group - Kishmish luchistyj (11,2 t/ha), Moldova (11,2 t/ha), with large clusters (266-453 g) and berries (3,2-7,0 g), a berries’ crush resistance was from average 850 g to high up to 1528 g, berries’ strength of attachment to fruitstems was high – 259 and solid – 666 g. It was observed the positive benefit of foliar application of a new generation of micro fertilizers. In the phase of ripening of berries the total length of shoots of fertilized variants was above the control variant for the variety Ranniy Magaracha on 2,6-13,4%, for the Karaburnu on 2,5-13,9%. Maturing shoots in this phase was on the variety Ranniy Magaracha – 76,5- 92,4% (control variant – 74,6%), while on the Karaburnu variety – 72,8-83,1% (control variant – 70,9%). Fertilizers contributed to the increase of leaf area on the Ranniy Magaracha variety on 3,9-15,9 thousand sq.m/ha (control variant – 20,0 thousand sq.m/ha), on the variety Karaburnu on 3,4-13,1 thousand sq.m/ha (control variant – 22,8 thousand sq.m/ha). The yielding capacity on the fertilized variants have increased by 7,1-23,0% depending on the variety. The maximum yielding capacity was obtained when using compound nanotechnological fertilizer Nagro on the variety Ranniy Magaracha – 13,4 t/ha and on the variety Karaburnu – 15,5 t/ha

Description
The experiments were conducted on bull-calf of Kazakh white breed at the age of 12 months. In the capacity of feed additives there were used "Yoddar-Zn", which consists of microelements as iodine and zinc in organic form, and the additive "Glimalask-Vet" based on organic acids (I gr.). A second group of animals received only a basic diet with "Yoddar-Zn» (II gr.) feed additives. In the organism of experimental groups of calves, the transformation proceeded more intensively for nutrient feed. This has contributed to increase the intensity of their growth, slaughter performance and the quality of the resulting beef. Bulls that received a ration feed additives had a live weight more on 35,9, and 20,4 kg, carcass weight after slaughter - at 22,27 and 11,47 kg, and the mass of flesh - at 20,9 and 8,50 kg., compared with the control. The average sample flesh of carcass fat content was higher by 1,25 and 0,74%, protein – 0,68 and 0,47%, iodine - at 39,30 and 26,71%. The animals of experimental groups in the edible portion of the carcass was synthesized as compared to control, more protein on 5,86 and 10,71% and energy - on 10,95 and 5,02%. The highest efficiency established at complex using both feed additives. Estimation of economic efficiency of use of these feed additives showed a decrease in cost and increase in profitability of beef production
