Abstract

The article is devoted to improvements in technology of corn production using liquid nitrogen fertilizers such as urea ammonium nitrate (UAN), in pure form UAN-32 or with the addition of sulphur UAN+S, with various methods of application before seeding or leaf-feeding dressings. This technology provides an increase in the corn yield with additional efficiency compared with the use of solid nitrogen mineral fertilizers like ammonium nitrate in conditions of insufficient moisture, which are typical of many regions of Russia and especially of the Volga region (Samara oblast).

Highlights

Due to the high nutritional and fodder characteristics of the corn agricultural crop, its production occupies a significant volume in the world, including Russia, increasing annually because of the high purchase price and the yield
A predominant increase in the yield and corn grain quality was observed with the use of liquid mineral fertilizers compared to solid ones (Table 2 and Fig. 2)
With an equal amount of nitrogen in all experiments, the highest corn yield of 84 c / ha on average over three years of research (2018-2019 was unfavorable in terms of moisture supply compared to average long-term data) was obtained with fractional application of liquid nitrogen-sulfur-containing mineral fertilizers on base of urea ammonium nitrate (UAN)

Summary

Introduction

Due to the high nutritional and fodder characteristics of the corn agricultural crop, its production occupies a significant volume in the world, including Russia, increasing annually because of the high purchase price and the yield. For the majority of arid regions, to which Samara oblast in the Russian Federation belongs (the place of the research), it is necessary to improve the cultivation technology of this hydrophilious crop with an increase in production efficiency primarily due to the optimal methods of using mineral fertilizers [1,2,3,4,5,6]. This situation is accompanied by the global problems of food and animal feed shortages, world's population growth, and an increase in the frequency of negative weather events, which are primarily associated with the so-called global warming [13,14,15,16]. The aim of the study was to substantiate the most effective technological methods for the corn cultivation in conditions of insufficient moisture using liquid nitrogen mineral fertilizers, such as urea ammonium nitrate (UAN), in pure form UAN-32 or with the addition of the most important and scarce chemical element sulphur UAN+S [3, 4, 6, 10,11,12]
