Influence of microfertilizers on water consumption ratio and yield of chickpea in the Saratov Trans Volga region

Abstract

The article shows the influence of the main tillage and mineral fertilizers with microelements on the water consumption coefficient and the yield of chickpea grain in the Saratov Trans-Volga region. On average, over three years in chickpea crops, the highest total water consumption was after subsoil tillage - 1240 m3 / ha, which exceeded the control by 64 m3 / ha. Minimal tillage led to an increase in the water consumption coefficient by 533 m3 / t, or 31%. After subsoil tillage it increased by 372 m3 / t, or 22% relative to conventional tillage. Foliar top dressing with microfertilizers in the chickpea branching phase reduced the water consumption ratio by 88–236 m3 / t, which amounted to 4.3–11.4%. A decrease in the depth of the main processing to 10–12 cm led to a 23.5% decrease in the yield of chickpea. Subsoil tillage reduced the yield by 10.3%. Combined soil cultivation did not provide a significant increase in yield relative to control. Foliar feeding of chickpeas in the branching phase with micronutrient fertilizers increases the yield by 5.1–11.9%.
