The influence of microfertilizers on productivity and quality of peas grain on sward-podzolic soils

Abstract

The research was carried out in 2001–2003 on sward-podzolic light-loamy soil of an experimental farm of the Belarusian State Agricultural University. The aim of the research was to establish the influence of non-root additional fertilization of peas in the budding phase by boron, molybdenum, cobalt, and complex microfertilizer “Mikom” containing boron, molybdenum, copper, and zinc on productivity and quality of peas grain, removal and coefficients of nutrients usage. Application of boron on the background of N50P50K90 increased peas grain productivity during 3 years on average by 0.33 t, molybdenum – by 0.26 t, cobalt – by 0.28 t, and complex microfertilizer “Mikom” – by 0.43 t/ha. Under the influence of cobalt and molybdenum the content of crude protein in peas grain increased by 1.0 and 1.1%. Peas non-root additional fertilization by boron, cobalt, molybdenum and complex microfertilizer “Mikom” increased the output of crude protein from 1 hectare in comparison with the background of N50P50K90 by 89, 94, 103, and 0.98 kg/ha, correspondingly. Under the influence of molybdenum, complex microfertilizer “Mikom” coefficients of fertilizers phosphorus usage increased.
