ФОРМИРОВАНИЕ ПРОДУКТИВНОСТИ ЭКОЛОГИЧЕСКИ ПЛАСТИЧНЫХ СОРТОВ ЯРОВОЙ ПШЕНИЦЫ В УСЛОВИЯХ ПРЕДВОЛЖЬЯ РЕСПУБЛИКИ ТАТАРСТАН

Abstract

The article is devoted to the issue of comparative cultivation of spring wheat varieties of different breeding schools: Simbirtsit - GNU Ulyanovsk Research Institute of Agriculture; Yoldyz GNU Tatar Research Institute of Agriculture; Ekada 109 - GNU Ulyanovsk Research Institute of Agriculture, Penza Research Institute of Agriculture, Bashkir Research Institute of Agriculture, Samara Research Institute of Agriculture; Balkysh - GNU Tatar Research Institute of Agriculture; Alvaris, Burlak - Penza Research Institute of Agriculture; Arhat - GNU Ulyanovsk Research Institute of Agriculture and Idelle - GNU Tatar Research Institute of Agriculture. Morphostructural indicators have varietal differences. On average, over three years, such varieties as Arkhat-91 cm, Balkysh - 73 and Ekada 109-72 cm turned out to be the tallest. In other varieties, this figure ranged from 67 to 71 cm. The largest number of spikelets in an ear, as well as the number of grains in an ear was formed in varieties Ekada 109, Yoldyz and Idelle. The largest leaf area per unit area on both feeding backgrounds was formed by varieties Ekada 109 – 33,2 ... 34,1 thousand m2 / ha and Arhat – 32,8 ... 33,5 thousand m2 / ha. Over the years of research, the yield of the tested varieties, both on the fertilized variant and on the natural background of nutrition, differed sharply. The most fruitful studies over the years have identified such indicators as Ekada 109 – 3,1 ... 5,79 t per ha, Burlak – 2,31 ... 4,91 and Yoldyz – 2,54 ... 4,3 application of fertilizers. The same varieties showed the best results on a natural background of nutrition. On average, over three years, the increase from different varieties was: in the variant without fertilizers, the variety Yoldyz 0,34 t/ha, Burlak 0,44 and Ekada 109 – 0,62 t/ha compared to the standard. On the variant with fertilizers 0,64; 0,97 and 1,24 t/ha, respectively.
