Title : INFLUENCE OF BIOGAS DIGESTATE, WOOD ASH AND THEIR MIXTURES ON THE YIELD AND QUALITY OF CUCUMBERS
Abstract : The biogas digestate can be as alternative of synthetic fertilizers in agricultural practice. Without additives, the drying of digestate can be unprofitable. The adding of wood ash to digestate dehydration process gives the opportunity for soil liming as well as for soil enrichment with nutrients. Within the framework in the Latvian National Research project, it was necessary to compare digestates from various raw materials and to test the possibility of mixing them with ash for using in cultivation of fast-growing crops. The research aimed to evaluation the influence of biogas digestate and wood ash on the yield and quality of cucumbers in polycarbonate greenhouse. The experiment was provided in 2020, using 11 fertilization treatments as well as peat (pHKCl 5.5) as control. Starting of experiment, no significant differences between acidy of substrates were observed, but at the end of investigations, pHKCl varied from 6.8 till 7.5, that was non-optimal for cucumbers growing. The development of plants under treatments was not significantly different (p>0.05). During experiment, cucumbers were harvested 23 times. The count of fruits per plant, depending on variant, per each harvesting varied from 1 till 9 (maximal result was observed for digestate from pig manure and horse manure). The significant influence of fertilization variant to cucumbers yield was observed (p <0.05). The organoleptic parameters were not differed significantly throughout the growing season (p>0.05).
