ΧΕΙΡΙΣΜΟΙ ΤΟΥ ΑΧΥΡΟΥ ΚΑΙ ΑΛΛΗΛΟΠΑΘΕΙΑ ΣΕ ΑΓΡΟΟΙΚΟΣΥΣΤΗΜΑΤΑ ΣΙΤΑΡΙΟΥ (TRITICUM AESTIVUM L. EM. TELL) ΚΑΙ ΚΤΗΝΟΤΡΟΦΙΚΩΝ ΚΟΥΚΙΩΝ (VICIA FABA L.).

THE RATE OF DECOMPOSITION AND NUTRIENT RELEASE IN DECOMPOSING WHEAT AND FABABEAN STRAW BURIED IN THE SOIL, WERE STUDIED FOR 2.5 YEARS (JANUARY 1984-JULY 1986). THE RATE OF BIOMASS LOSS OF BOTH SPECIES WAS CONSTANT. THE PROPORTION OF ORGANIC MATTER IN THE UNDECOMPOSED BIOMASS WAS STEADILY REDUCED WITH TIME: TOTAL N AND P WERE REDUCED TOWARDS THE END OF THE EXPERIMENTS BUT NOT SIGNIFICANTLY. THE CIN RATIO OF BIOMASS WAS REDUCED WITH TIME. THE RATE OF K AND MG RELEASE WAS HIGHER DURING THE RAINING PERIOD THAN DURING THE DRY ONES. THE RATE OF CA RELEASE WAS SIGNIFICANT ONLY IN FABABEAN STRAW AND WAS NOT AFFECTED BY RAINFALL. TWOMANIPULATIONS OF STRAW, NAMELY, SOIL INCORPORATION AND BURNING, WERE STUDIED AS REGARDS THEIR EFFECTS ON WHEAT AND FABABEAN GROWTH. EXPERIMENTS WERE CARRIED OUT IN THE FIELD (1983-1986) AND IN THE GLASSHOUSE (1983). FIELD EXPERIMENTS SHOWED THAT STRAW INCORPORATION DID NOT INFLUENCE WHEAT GROWTH, WHILE STRAW BURNING EITHER REDUCED OR TENDED TO REDUCE WHEAT GROWTH. WHEAT GROWTH WAS DECREASED BY ADDITION OF STRAW IN POTS, WHILE STRAW BURNING INCREASED IT. ON GENERAL, FABABEANS WERE NOT AFFECTED BY ANY OF THE TREATMENTS APPLIED. IN LABORATORY AND GLASSHOUSE EXPERIMENTS, THE EFFECT OF EXTRACTS FROM WHEAT AND FABABEAN STRAW, FOLLIAGE, SEEDS, AS WELL AS OF ROOT EXUDATES WAS TESTED ON SEED GERMINATION, SEEDLING AND PLANT GROWTH OF BOTH SPECIES, USING DIFFERENT CULTURE MEDIA. EXTRACTS FROM STRAW AND FOLLIAGE, AS WELL AS ROOT EXUDATES REDUCED SEED GERMINATION, SEEDLING AND PLANT GROWTH. THE EFFECT WAS LESS PRONOUNCED AS THE GROWTH MEDIUM BECAUSE MORE COMPLEX AND ACTIVE.
