QUALITY OF SWEET CORN YIELD DEPENDING ON WINTER CATCH CROPS AND WEED CONTROL METHOD
2015
Rosa, Robert
A special role in improving soil fertility is ascribed to green manures. Organic manuring can also influence on the quantity and quality of vegetable yield. The secondary effect of winter catch crops (VV – hairy vetch, TR – white clover, SC – rye, LM – Italian ryegrass, BRT – turnip rape) and weed control methods on the yielding, biometric parameters of ears and selected components of nutritive value in sweet corn were examined. The effects of an application of green manures were compared to the effect of farmyard manure (FYM ) – 30 t·ha-1 – and control treatment without organic manure (NOM). Two methods of weed control were used: hand weeding and a mixture of herbicides Mustang 306 SE (florasulam + 2.4 D) + Titus 25 WG (rimsulfuron). Cultivation of sweet corn after FYM and VV most beneficially affected the crop’s yield performance, ear weight, kernel weight per ear and sugars content. Ears were the longest when harvested in FYM and VVplots and NOM whereas ear fulfillment was the best in FYM and TR plots. Ear diameter was the greatest for sweet corn cultivated after FYM, LM and BRT. The highest dry matter content was determined in kernels of corn following LM and protein content after LM, VV and TR. Ascorbic acid content increased after all the catch crops compared with FYM and NOM. When weeds had been chemically controlled, corn produced larger ears which, however, had less kernel rows compared with hand weeded plants.
