This article presents the results of determining the attracting ability of the whole box and the degree of its differences depending on the genotypes, as well as its prospects for solving practical problems of selection of medium-fiber cotton. Consequently, among the genotypes studied by us, a significant amount of the attractive ability of a single box, the value of attraction and the mass of raw cotton per box differed in 10 combinations, which are economically the most productive.

Some economically valuable traits of upland cotton genotypes are being considered in comparison with standard cultivar “Hisor”. Based on the results, it was established that the yield of raw cotton for all studied genotypes is 66.4-100.1 g/plant. In a comparative analysis of highly productive genotypes, 3 genotypes were distinguished – ALC-86/6 x Sorbon, DP-4025 x Dusti-IZ, NAD-53 x Sorbon, varying from 95.0 to 100.1 g/plant, exceeding the standard cultivar “Hisor” (40,8 g/plant) by 54,2-59,3 g/plant.

The highly variable weather under changing climate conditions affects the establishment and the cutoff of crop growing season and exposes crops to failure if producers choose non-adapted relative maturity that matches the characteristics of the crop growing season. This study aimed to determine the relationship between maize hybrid relative maturity and the grain yield and determine the relative maturity range that will sustain maize production in northwest New Mexico (NM). Different relative maturity maize hybrids were grown at the Agricultural Science Center at Farmington ((Latitude 36.69° North, Longitude 108.31° West, elevation 1720 m) from 2003 to 2019 under sprinkler irrigation. A total of 343 hybrids were grouped as early and full season hybrids according to their relative maturity that ranged from 93 to 119 and 64 hybrids with unknown relative maturity. The crops were grown under optimal management condition with no stress of any kind. The results showed non-significant increase in grain yield in early season hybrids and non-significant decrease in grain yield with relative maturity in full season hybrids. The relative maturity range of 100–110 obtained reasonable high grain yields and could be considered under the northwestern New Mexico climatic conditions. However, more research should target the evaluation of different planting date coupled with plant population density to determine the planting window for the early season and full season hybrids for the production optimization and sustainability.
