<i>Satureja montana</i> L. Cultivated under Polypropylene Woven Fabric on Clay-Textured Soil in Dry Farming Conditions
Abstract
During a five-year field trial established with Satureja montana L. under polypropylene woven fabric (PPWF) on clay-textured soil in dry farming conditions in South Banat, Serbia, the influence of a single basal application of compost and mineral fertilizers at different planting densities (3.6 and 5 plants m−2) on the yield was investigated. Single-dose fertilization positively influenced the yields of S. montana in both applied fertilization models. In the third production year, the dry herb yield achieved by applying organic fertilizers in dense cultivation (1016 g m−1) was comparable with that obtained in the mineral plot (961 g m−1). Furthermore, the plants were optimally supplied with N, P, and K macronutrients, with equal amounts removed by yield, in both tested fertilization plots. The use of PPWF proved beneficial to cultivated plants in terms of water-use efficiency and weed suppression. However, severe yield loss was observed in the fourth and fifth production years as a result of the extreme rainfall conditions; the excess moisture retained by PPWF applied to heavy clay soil favored the development of soil-borne pathogens. Other mulch materials should be further investigated for the production of S. montana on heavy clay soil.
