V. I. Pushchak<\/strong><\/p>\n

It was discovered that under conditions of sufficient humidity of the western forest-steppe of Ukraine the highest <\/em>yield<\/em> has the Yarina variety (2.82\u20133.40 t\/ha), somewhat lower the Pamyat variety (2.60\u20133.15 t\/ha), while the lowest yield was observed in the Triumf vatiety (1.72\u20132.20 t\/ha). The lowest yield of Triumf variety in our research could be explained by its less resistance to infectious diseases under conditions of the western forest-steppe. <\/em><\/p>\n

It was revealed that among the six studied sowing rates, i.e. 0.4, 0.5, 0.6, 0.7, 0.8, and 0.9 mln\/ha, the highest yield under conditions of the western forest-steppe was obtained in the range of sowing rates of 0.7\u20130.8 mln\/ha in all <\/em>cicer arietinum<\/em>varieties. The variety Yaryna at such sowing rates demonstrated the yield of 3.31\u20133.40 t\/ha, which is more than the yield of Pamyat variety by 0.21\u20130.25 t\/ha and of Triumf\u00a0 variety by 1.17\u20131.20 t\/ha. Under conditions of sufficient moisture, as it was expected, the lowest yield was obtained at minimal sowing rates. For instance, the yield of Yaryna variety at a sowing rate of 0.8 mln\/ha was 3.40 t\/ha, while at 0.4 mln\/ha it was only 2.82 t\/ha, i.e. lower by 0.58 t\/ha. The same pattern was observed in case of other <\/em>varietie<\/em> as well. <\/em><\/p>\n

It was discovered that the <\/em>cicer arietinum<\/em> yield grew up to 2.30 t\/ha, or by 1.02 t\/ha, when the soil herbicide Reiser KE (2.5 l\/ha) was used. When the herbicide was applied, the yield almost doubled, while during appling the Fastak, K.E. (alpha-cypermethrin, 100 g\/l) in a concentration of 0.15 l\/ha had no effect on the yield.<\/em><\/p>\n

In case of the three-step application scheme of fungicides such as Rex Duo, KS (epoxiconazole, 187 g\/l + thiophanate-methyl, 310 g\/l) in a concentration of 0.5 l\/ha at the early phase of budding, Abacus (pyraclostrobin, 62.5 g\/l + epoxiconazole, 62.5 g\/l) in a concentration of 1.5 l\/ha during flowering, and Folikur 250 EW, WB (tebuconazole, 250 g\/l) in a concentration of 1.0 l\/ha during seed filling, the yield increased by 0.90 t\/ha compared to the variant where fungicides were not applied. In total, due to the use of plant protection products in the experiment, the yield increased from 1.28 t\/ha to 3.21 t\/ha, i.e. by 1.93 t\/ha (150.8 %).<\/em><\/p>\n
