Abstract

 Background and Objectives: Application of organic amendments such as spent mushroom compost has received significant attention due to achieving sustainable production and healthy yield. Considerable amounts of spent mushroom compost are produced in mushroom production. Application of this byproduct from sustainable agriculture standpoint especially in organic matter deficient soils such as Iranian soils is important. Therefore, this greenhouse research was conducted in a sandy soil to investigate washed and unwashed spent mushroom compost effects on vegetative growth properties and MACROELEMENTS (N, P, K and Ca) uptake in LETTUCE(lactuca sativa L. cv Syaho).Materials and Methods: This research was carried out based on completely randomized experiment with five replications. Experimental treatments were 0 (control), 10, 20, 30, 40 and 50% of washed and unwashed spent mushroom compost (SMC) in a sandy loam soil. Some physicochemical properties and bioavailable concentration of MACROELEMENTS were measured before planting in all treatments. After growing period, LETTUCE was harvested and growth properties such as plant height, leaf number and surface, chlorophyll content and stomatal conductance of leaves, dry and wet weight and MACROELEMENTS concentration in LETTUCE were measured. Comparison of mean analysis was done by SPSS software.Results: Washed and unwashed spent mushroom compost addition increased organic matter, electrical conductivity, total nitrogen and bioavailable concentration of P, K, Ca and Na in a sandy soil in comparison with control. Increasing organic matter content is one of the main advantages of organic fertilizers because of improving soil quality and consequently crop production in organic matter deficient soils of arid and semi-arid regions. Results showed that application of SMC in soil had significant effect (P£0.01) on LETTUCE growth properties and N, P, K and Ca content. Maximum and minimum amounts for most properties were obtained in 30% washed spent mushroom and control, respectively. Leaf analysis results showed that macroelement concentrations have been reached close to optimum level due to application of SMC.Conclusion: Application of spent mushroom compost improved growth, yield and nutritional quality of LETTUCE in comparison with control because of increasing organic matter content and bioavailability of MACROELEMENTS. Orthogonal comparison showed that washed spent mushroom compost in comparison to unwashed one had significant effect on measured parameters (P<0.01). Therefore, washed spent mushroom compost can be used as a suitable amendment with low salinity to improve nutrient supply characteristics and increasing soil fertility in arid and semi-arid region. Our results showed that washed spent mushroom compost can be used to produce organic LETTUCE and supply its nutrient requirement to some extent without using chemical in greenhouse condition.
