In a 3-year experiment, the effect of catch crop management [catch crop incorporated in autumn (A) or mulched (B) vs plots without a catch crop (C)] on soil acid (PAC) and alkaline (PAL) phosphatase activities as well as on the available phosphorus content (PAVAIL) were investigated on typical Alfisol. The catch crops were sown at the beginning of August and ploughed in the autumn in 2008, 2009, and 2010, or left as mulch during the winter. Soil samples were taken four times a year from spring barley plots that were grown in 2009, 2010, and 2011. Generally, catch crop treatment significantly influenced the enzymatic activity as compared to the control. The PAC activity was significantly greater with a mulched catch crop than in a ploughed one only in I and II sampling dates, whereas the PAL activity was not influenced by the method and time of field pea management. The time of sampling significantly influenced the PAL activity in 2011 and the PAC activity in 2009 and 2011.

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 VV plots 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.

The work presents the results of investigations conducted in 2004- 2007 to evaluate the residual effect of summer catch crops ploughed as green manures on productive-economic effects of sweet corn cultivation. The experiment was carried out in east-central Poland (52°03’N, 22°33’E). The following summer catch crops were grown: phacelia, amaranth, sunflower, serradella and faba bean. The catch crop seeds were sown in 2004-2006 at three dates: on the 21stJuly, 4th and 18th August. The effect of summer catch crops was compared to FYM applied at the rate of 40 t·ha-1. The catch crops biomass (roots + above ground parts) and FYM were incorporated in the third decade of October. Sweet corn seeds (6 kg·ha-1) were sown in mid-May, in the years 2005-2007, at the between – and inter- row spacing of 65 × 20 cm. Sweet corn ears were hand-harvested at the stage of milk maturity of kernels, at the turn of August and September. During the harvest marketable yield of ears (t·ha-1) and number of marketable ears per 1 ha were determined. Economic evaluation of sweet corn cultivation under diversified organic fertilization was conducted according to the standard gross margin method. The calculation was based on the 2014 prices. The highest yield and number of ears were obtained after catch crops with faba bean and phacelia sown on the 21st July and after FYM. Delaying the sowing date of catch crops resulted in a decrease in the successive yielding effect. The highest gross margin (25267.66 PLN·ha-1 and 0.56 PLN per 1 ear) and profitability index (332%) were achieved in the sweet corn cultivation after catch crop with faba bean sown on the 21st July. Compared to the plot with FYM, a higher level of gross margin and profitability index were obtained after all catch crops sown on the 21st July and the 4th August. Irrespective of investigated factors, profitability index was on a very high level amounting to 211-332%.

A field experiment was conducted in central-eastern Poland in the years 1999-2003. It analyzed the effect of catch crop green fertilizers on soil humidity in a three-year-long crop vegetable rotation (white cabbage, onion, red beet). Oats, field pea and spring vetch cultivated in pure sowing and as mixtures were used as green fertilizers. The effect of green manures was compared with ploughed in farmland manure in the dose of 25 t·ha-1 and the control without any organic fertilization. White cabbage was grown in the first year after organic fertilization, onion – in the second and red beet – in the third.
