Abstract
The aim of this study was to investigate the effectiveness of different organic mulch materials and thicknesses in controlling weeds, improving soil temperature and moisture, and increasing crop yield in Capsicum annuum L. cultivation. The experiment was conducted in 2022, using three types of mulch materials (grass, chopped paper, wheat straw) and three different thicknesses (5 cm, 10 cm, 15 cm). A total of 22 weed species were identified in the experimental area, and statistical analysis revealed significant differences in all parameters between the mulch treatments and the control group. The use of organic mulch resulted in better weed control, with an increase in mulch thickness corresponding to greater suppression of annual weed species. The highest effect on weed dry weight was observed in the 15-cm paper mulch, which also produced the highest yield (3940.48 kg/da). The study also showed that soil temperature was lower and soil moisture was higher in all mulch treatments compared to the bare soil control group, with some fluctuations observed at times. Overall, the findings suggest that the use of organic mulch is crucial in arid and semi-arid regions for effective weed control, water conservation, improved water efficiency, reduced soil evaporation, and increased pepper yield.
