Установлено, что на пойменных почвах использование методов диагностики минерального питания растений моркови «по почве» и «по черешку» в фазу начала образования корнеплодов позволяет значительно (на 36–42%) снизить расход минеральных удобрений, обеспечивая урожайность моркови на уровне 70 т/га с долей стандартной продукции 78–81% без существенного изменения качества корнеплодов.It was found that in floodplain soils, the use of methods of diagnosis of mineral nutrition of carrot plants «on the soil» and «on the petiole» in the phase of the beginning of the formation of root crops can significantly (by 36–42%) reduce the consumption of mineral fertilizers, ensuring the yield of carrots at the level of 70 t/ha with a share of standard production of 78–81% without significantly changing the quality of root crops.

The duration of productive use is a complex integral feature and is determined by both genetic and paratypical factors. This feature should ensure maximum milk productivity of animals, economic efficiency of dairy farms and generally limit the cost of raising and keeping cows. Research conducted in the experimental farms of state enterprises "Kutuzovka", Kharkov district of Kharkov region using cow’s Ukrainian black-and-white dairy breed (4038 cows). We studied the duration of productive use of cows divided into gradations according to the conditional bloodline for the Holstein breed, depending on the weight in the control age periods of cultivation (at birth, at 6, 12 and 18 months). The maximum value of the duration of productive use was recorded in the group of cows with a share of conditional blood for the Holstein breed up to 30% inclusive (the average duration of productive use is 2.77 lactations). The highest indicator of the duration of productive use of the studied animals was 4.09 lactations. Among cows with a share of conditional blood for the Holstein breed up to 30% longer produced those born with a weight of more than 40 kg (4.09 lactations), at 6 months of age weighed 100-149 kg, at 12 months – 200-249 kg, at 18 months of age – 350-399 kg. Among animals with a share of bloodline of 31-60 %, those that had a weight at the age of 6 months produced the longest: 155-190 kg (3.17 lactations), at 12 months – 250-299 kg (2.98 lactations), at 18 months – 350-399 kg (3.06 lactations). In the most numerous gradation with the share of bloodline for the Holstein breed 61-90 %, the longest productive use was characterized by animals born with a weight of 30-39 kg (2.12 lactation), at 6 months of age they weighed more than 200 kg (3.29 lactation), at 12 months-300-349 kg (3.40 lactation), at 18 months – 400-449 kg (2.82 lactation). The average duration of productive use of cows of this grade is quite low – in the range of 2.82-3.29 lactations. The highest degree of influence on the duration of productive use in this gradation of animals was recorded by the live weight factor at 6 months of age (η2 = 10.8). Сcomparative assessment of the cows gradation with a share of conditional blood for the Holstein breed of 91 % or more found that the longest productive use was characterized by cows that had a live weight at birth of 30-39 kg (1.93 lactation), in 6 months – 155-199 kg (2.73 lactation), in 12 months – 250-299 kg (2.87 lactation) and in 18 months – 350-399 kg (2.62 lactation). The degree of influence of live weight at this age on the duration of productive use of cows is insignificant, except for live weight at 6 months of age (η2 = 11.8).

AbstractStereotypes matter for economic interaction if counterparty utility is informed by factors other than price. Stereotyped agents may engage in efforts to counter stereotype by adapting to in-group standards. We present a model informing the optimal extent of these efforts depending on an agent’s (a) share of total transactions between out- and in-group agents; and (b) share of repeated transaction pairings with in-group counterparties. Low values of (a) suppress the effect of adaptation efforts on the stereotype itself (persistence). In turn, low values of (b) mean that out-group agents cannot dissociate from stereotype (stickiness). Significantly, the model implies that the optimum level of effort may require adaptation beyond in-group standards, and that such over-adaptation attains maximum likelihood in cases where stereotype is sticky and persistent at the same time. We test our model with data on private equity buyout investments conducted in Japan between 1998 and 2015 by domestic Japanese and Anglo-Saxon funds. We document that the latter not only adapt, but eventually over-adapt. In addition, we show that their efforts are effective in reducing a premium initially asked by domestic counterparties.

To cope with climate change and achieve sustainable development, low-carbon city pilot policies have been implemented. An objective assessment of the performance of these policies facilitates not only the implementation of relevant work in pilot areas, but also the further promotion of these policies. This study uses A-share listed enterprises from 2005 to 2019 and creates a multi-period difference-in-differences model to explore the impact of low-carbon city pilot policies on corporate green technology innovation from multiple dimensions. Results show that (1) low-carbon city pilot policies stimulates the green technological innovation of enterprises as manifested in their application of green invention patents; (2) the introduction of pilot policies is highly conducive to green technological innovation in eastern cities and enterprises in high-carbon emission industries; and (3) tax incentives and government subsidies are important fiscal and taxation tools that play the role of pilot policies in low-carbon cities. By alleviating corporate financing constraints, these policies effectively promote the green technological innovation of enterprises. This study expands the research on the performance of low-carbon city pilot policies and provides data support for a follow-up implementation and promotion of policies from the micro perspective at the enterprise level.
