标题：THE EFFECTS OF AGRICULTURAL WASTE COMPOSTS (BANANA PLANT WASTES-GREENHOUSE WASTES-SPENT MUSHROOM COMPOSTS) ON MINERAL COMPOSITION AND QUALITY PARAMETERS OF LETTUCE (LACTUCA SATIVA L.)
摘要：Agricultural waste is generally disposed of without being utilized on agricultural land. It is estimated that such waste is of large volume with different types and amounts linked to production regions. Both environmental pollution and rich nutrient contents need to be converted into fertilizer. The aim of this research was to determine the effects of organic fertilizer prepared from the composting of banana plant waste, greenhouse waste and spent mushroom compost on the development, morphology and productivity of lettuce. The composts used consisted of different agricultural waste; banana plant waste (BPW), greenhouse plant waste (GPW), and spent mushroom compost (SMC). In these experiments, compost was used at 5 different levels for each 1 ton ha-1 of pot soil and the effects on growth and mineral nutrient contents of lettuce plants were investigated during two successive seasons (autumn and spring). The results showed that the compost treatments had positive effects on lettuce growth parameters and treatments of M3 (50%BPW+40%GPW+10%SMC) and M4 (40% BPW+50%GPW+10%SMC) in the lettuce yield values came to the forefront in both seasons compared to the control group. M1 (70%BPW+20% GPW+10%SMC) application was determined to be the best practice in mineral nutrition of lettuce.
