Application of chelated fertilizers on irrigated vegetable crops in the Saratov Zavolzhye

Abstract

The effect of chelated fertilizers that produced by the NPO "Power of Life" on the productivity of the main vegetable crops was studied in field experiments on irrigated terraced dark chestnut soils of the Saratov Zavolzhye (Trans-Volga region). It was established that the yield of the vegetable crops under study increases with the use of fertilizers based on humic acids. The increase in yield due to reasil micro hydro mix was: 35.8% of cucumber, 28.3% of red beet roots, 22.6% of tomato, 20.9% of late white cabbage, 9.1% of onion, 6.8% of carrot roots. The reasil micro hydro mix was more effective than potassium-sodium humate with trace elements, for all the studied vegetable crops under study. The average increase in productivity was 20.6% versus 16.0%. The effect of chelated microfertilizers on the yield of vegetable crops was ambiguous. A significant reliable increase in yield due to all the studied chelated microfertilizers, used both together with reasil micro hydro mix, and together with potassium-sodium humate with trace elements, was established only when growing onions. An additional increase in the yield of red beet roots 4.42 t / ha was obtained only when treated with reasil humic N on the background of potassium-sodium humate with trace elements. An additional increase in the yield of late white cabbage was 9.23 and 8.15 t / ha when treated with reasil Mg, respectively, against the background of reasil micro hydro mix and potassium-sodium humate with trace elements. On tomatoes, chelated microfertilizers were effective only against the background of potassium-sodium humate with trace elements. Cucumber responded positively to all chelated microfertilizers on the background of potassium-sodium humate with trace elements, as well as to reasil humic N and reasil Ca/Mg/B on the background of reasil micro hydro mix. On carrots, a significant increase in yield was obtained when treated with reasil Ca, reasil Ca/ Mg/ B and reasil humic N against the background of reasil micro hydro mix.
