Abstract

In desert conditions, corn is one of the most promising crops due to its resistance to salinity, drought, heat, adverse environmental conditions, high productivity and versatility. Conducting field experiments, sowing, phonological observations, biometric measurements, plant care, yield determination new varieties of agricultural crops were performed. Samples were also evaluated on the length of the paniculo. In particular, it was 44.7 cm in the control K–521, followed by 40.8 cm in K-431, 49.9 cm in K-581 and 55.4 cm in K-538, whereas in the technical variants, it was 55.4 cm in K-538, 50 cm at K-368, and even it was 65 cm in K-494. Of the 57 samples studied, only 8, № 9, 15, 17, 26, 27, 31, 42, 46 samples were found suitable for future selection work. Valuable aspects of these samples were that flowering period was 75-108 days, milk-ripening period was 87-108 days, and full ripening period was 118-130 days. These indicators were 76 days of germination, 79 days of flowering, 91 days of milk ripening and 127 days of full ripening in the “Orange-160” maize. It was found that the repining period of “Orange” maize was 9 days earlier than the control varieties, 9, 15 and 17.

Highlights

Corn (Maize) is the fifth most common cereal crop in world agriculture, and is grown on about 50 million hectares of land in 85 countries [1,2,3]
Of the 85 samples studied, only 8 pieces, that was 2, 38, 55, 61, 63, 79, 84, 85 finite samples were evaluated as fit for future selection studies (Table 1). Valuable aspects of these samples were manifested in the following: flowering period 56-80 days, milk ripening period 69 - 102 days, full ripening 86 - 115 days. These indicators, fasting in 5 varieties of template Uzbekistan accounted for 66 days, flowering 70, milk ripening 87, full ripening 107 days, and the selected samples were determined that the ripening period compared to the template variety was homogeneous
The number of leaves in the soil-climatic conditions of Uzbekistan is important in increasing the yield of photosynthesis and heat resistance, as well as leaf yield

Summary

Introduction

Corn (Maize) is the fifth most common cereal crop in world agriculture, and is grown on about 50 million hectares of land in 85 countries [1,2,3]. Due to water shortages in 80 countries around the world, 7 million people die every year. The problem of food security is growing due to the loss of agricultural land per hectare and global climate change. In order to meet the needs of the population in food, industrial raw materials and livestock feed by increasing the volume of production using irrigated lands in the world, it is necessary to systematically improve the technology of cultivation, taking into account the morphobiological properties of field crops, soil and climate, water supply [6-7, 11-12 ].
