New Preparations for Winter Wheat Seeds Protection

The research results into the different seed dressing agents effect on winter wheat seeds sowing qualities are presented. In the experiment, effective combination preparations with multilateral insectofungicidal activity were studied. The presence of several active substances in the preparation reduces the pesticide burden on the environment. Under field conditions close to production conditions the Sistiva, Kuinto Duo, Imidashans, Chansometox, Shansil Ultra, Shansil Trio, Vaibrans Integral, Celest Max, Celest Top effect at recommended doses were studied. At present, for winter wheat seed dressing it is best to use insectofungicide preparations containing different chemical classes several components. The best indicators for productivity (7.23 t/ha) and grain quality among the studied preparations were obtained by using a four-component insectofungicide for winter wheat seed disinfestation Vaibrans Integral, KS at the rate of 2l/t. Its use provides not only high yield but also particularly high protein content in the grain (16.07%) and gluten (36.8%) of the first quality group. If we take the winter wheat yield as a basis, in this indicator terms the worst performance was that of Celest Top. Nevertheless, all the studied preparations can be used to disinfect winter wheat seeds from seed and soil infections, as well as from harmful insects of the early period of plant development.

AbstractQuantifying reasonable crop yield gaps and determining potential regions for yield improvement can facilitate regional plant structure adjustment and promote crop production. The current study attempted to evaluate the yield gap in a region at multi-scales through model simulation and farmer investigation. Taking the winter wheat yield gap in the Huang-Huai-Hai farming region (HFR) for the case study, 241 farmers’ fields in four typical high-yield demonstration areas were surveyed to determine the yield limitation index and attainable yield. In addition, the theoretical and realizable yield gap of winter wheat in 386 counties of the HFR was assessed. Results showed that the average field yield of the demonstration plots was 8282 kg/ha, accounting for 0.72 of the potential yield, which represented the highest production in the region. The HFR consists of seven sub-regions designated 2.1–2.7: the largest attainable yield gap existed in the 2.6 sub-region, in the southwest of the HFR, while the smallest was in the 2.2 sub-region, in the northwest of the HFR. With a high irrigated area rate, the yield gap in the 2.2 sub-region could hardly be reduced by increasing irrigation, while a lack of irrigation remained an important limiting factor for narrowing the yield gap in 2.3 sub-region, in the middle of the HFR. Therefore, a multi-scale yield gap evaluation framework integrated with typical field survey and crop model analysis could provide valuable information for narrowing the yield gap.
