Abstract
ABSTRACT The investigations on the utilization of rice straw compost aimed to evaluate its effect as an additive at 30% (v/v) under two stress cycles with two growing media, soilless media (coconut coir dust and peat 3:2) and greenhouse soil (top soil, sand and peat 2:1:2) on yield, quality components and water use efficiency (WUE) of tomato grown under a protected environment. The addition of rice straw compost at 30% (v/v), significantly (p < 0.05) increased plant dry biomass, fruit diameter, yield and WUE in both media, whereas the water deficit significantly (p < 0.05) decreased these parameters in most of the treatments. Soilless media amended with rice straw compost resulted in the greatest water use efficiency. The application of rice straw compost, however, had the opposite effect on total organic matter in the two media. The total organic matter significantly (p < 0.05) increased in the greenhouse soil, while it significantly (p < 0.05) decreased in the soilless media. Days to 100% wilt were significantly positively correlated (R2= 0.90) with the total organic carbon of the media so that increases in total organic matter resulted in decreases in the number of days to 100% wilt of plant. Thus, whenever the total organic matter increased, decreases in the loss of media moisture content occurred. Utilization of rice straw compost, as an additive for growing media at 30%, significantly increased total yield and WUE by up to 70% and 34% for soilless and greenhouse soil, respectively.
