AGROCHEMICALS GROWTH REGULATORS ON ALFALFA

abstract 1081504091 issue 108 pp. 1234 – 1255 30.04.2015 ru 547
One of the methods of increasing the productivity of alfalfa is the use of growth regulators, and the use of polymeric compositions of growth regulators, binders with synthesized growth regulators of sim-triazine series is promising with the possibility of creating environmentally friendly technologies for growing alfalfa. Studies have shown that the application of the test on alfalfa growth regulators has a positive effect on growth, physiological and morphogenetic processes, plant resistance to adverse environmental conditions. Intensity impact on plant growth regulators depends on the type of plant growth regulators, concentration and method of application. Processing alfalfa seed growth regulators on germination increases energy 3,0-14,0 % germination on 8,0-17,0 %. Processing plant growth regulators to enhance the growth of plants in height (on the 7th day – 2,6-11,9 % , on the 14th 41,9-48,0 %) , the growth of aboveground biomass , expands on the number of productive branches of the 1st ( 24,1-41,3 %) and 2nd order (21,7-55,0 %). Pre-sowing seed treatment and plant growth regulators alfalfa sim- triazine series contributed to the increase in seed yield of 15,5 %. On average, the yield of green mass increased by 0,8-2,4 t /ha or 5,2-15,5 % and seed yield at 0,19-0,42 h/ha or 8,7-19, 3 %. Growth regulators of sim-triazine series increase the protein content of the vegetative mass of alfalfa at 3,2-4,6 %

MICROELEMENTS IN SUNFLOWER CROPS

abstract 1071503039 issue 107 pp. 563 – 577 31.03.2015 ru 745
The obtained experimental data show that the incorporation of trace elements into the system of the sunflower crop has a positive impact on the mineral nutrition of plants, the number and quality of the crop. Foliar feeding of sunflower crops with micronutrients improves nutrition of plants with nitrogen, phosphorus and potassium, thus creating the preconditions for the formation of highly agrocenosis. The seed yield of sunflower increased by variants with application of micronutrients 1.2-3.5 t/ha or 4.4-12.9 percent. The greatest impact of treatment with boron and copper, exceeding the background option 3.1-3.5 t/ha or 11.5-12.9% respectively. The crop is least influenced by manganese and molybdenum. The examined elements positively influenced the structure of the sunflower crop. The greatest influence on the diameter of the basket, the number of seeds, weight of seeds in the basket, the weight of 1000 seeds was provided by the zinc and copper. Trace elements contributed to the improvement of quality indicators of sunflower. For husk content, the greatest positive effect was cobalt, zinc, manganese and copper, increasing the background option 10.1, 10.4, 10.5 and 10, and 6%, respectively, on the oil content of sunflower seeds had cobalt, copper and zinc. The oil content on these options amounted 55,0, with 55.1 and 55.2%, respectively, increasing this figure by 1.5 to 1.7 %. The acid number at variants with boron, manganese and zinc was the same with the background option and amounted to 1.8. The greatest influence on iodine number provided molybdenum, zinc and copper, which accounted for 170,5, 171,2 and 171,4, exceeding the background option 10.2 and 11.1
