:Abstract  Growing plants in substrates are developing due to many advantages such as plant nutrient control, increasing product quality and quantity that soil cultivation and increasing performance. The purpose of this research is to investigating effect of particles size and ...

:Abstract Decomposition of organic waste in cropland led to production of contaminated liquid named (leachate) that has toxic and hazardous compositions, so it is considered a significant threat for the environment. In this study, Nutrient Film Technique (NFT) with filtered ...

:Abstract Hydroponics culture have many advantages such as increased yield, health and uniform product, conservation of water and land , better protect , control of environmental pollution and reduce of workers for cultivation. So in recently years, usage of organic ...

:Abstract Use of suitable growing media in soilless culture or substrate high quality is essential for production of crops. The aim of this study was to find out the effects of culture substrates on tomato fruit nutrient (N and K) ...

:Abstract In recent years, a wide range of soilless culture techniques have been developed and commercially introduced for intensive production of horticultural crops, particularly in greenhouses. Reasons for replacing soils as growing media arise from plant protection problems with soil-borne ...

:Abstract Due to the limitation of suitable water for crop production in the world, recycling water is among the most proper methods enhancing water efficiency and availability. One modern method, which is of economic, health, and environmental significance, and may ...

:Abstract The aim of this study was to compare between postharvest tomato quality of mature-green and red- ripe stages produced in soilless culture. The research was conducted in a completely randomized design with 3 replications. The treatments included: palmpeat 1 ...

:Abstract Background Physical properties of substrates considered appropriate for plant growth at planting may change over time in containers as a result of several processes. Changes include air space reduction, shrinkage of the substrate, organic matter decomposition, and physical breakdown ...

:Abstract  In many countries, soilless culture techniques are used for production, especially in greenhouses. The experiment was conducted as split factorial in a completely randomized block design with 27 treatments and 4 replications. Treatments included three particle sizes (S1= <0.5, ...

:Abstract The experiment was conducted as factorial in a completely randomized block design with 27 treatments and 4 replications under greenhouse conditions. Treatments included three sizes (S1= <0.5, S2= 0.5-1 and S3=1-2 cm), three composting times (C1=0, C2=3 and C3=6 ...
