Revisited the matter of the fodder galega new feed crop cultivation on the irrigated lands of the Lower Volga region

Abstract

The research results carried out on light-chestnut soils in 2011-2017 are presented, in order to determine the rational parameters of the water, nutritional regimes of the soil and various varieties of fodder galega to create highly productive herbage with their long-term use. The study of the fertilizers calculated doses influence and various pre-irrigation soil moisture thresholds on the herbage density showed that the maximum number of shoots was formed in the Magistr variety crops while maintaining an 80% moisture threshold due to an improved nutritional background. Under the same growing conditions, the highest symbiotic activity and photosynthetic activity of plants were noted. The yield of the fodder galega was significantly influenced by the moisture supply and the nutritional medium. The pre-irrigation soil moisture threshold maintaining at 80% minimum water capacity and the fertilizers application contributed to the formation of 47-83 t / ha of green mass, which meets the high requirements for the feed quality assessment. The accumulation of the root mass contributed to the enrichment of the soil with organic matter and nitrogen, most of which was obtained through the work of nodule-forming bacteria.

Influence of tillage methods on food security and its agrophysical and water-physical properties

“…Numerous studies have shown that the supply of productive moisture in the soil depended on its type, methods of cultivation, the depth of cultivation, and the time of its implementation (de Lima et al, 2021;Mesterházy et al, 2020). According to Burtseva et al (2021), on light chestnut soils of the Lower Volga region, the most favorable water regime is formed with non-moldboard tillage with subsurface cultivators and SibIME stands while maintaining the maximum amount of stubble, which contributes to the complete assimilation of precipitation. Due to the deterioration of the water regime, shallow soil cultivation can be used in combination with periodic deep or other methods of decompaction of the lower soil layers, primarily in years with its low autumn moisture load.…”
