composting of organic agricultural wastes is a sustainable method for recycling of the wastes. for determining the effects of tea waste compost (twc) and tree bark compost (tbc) on growing media and some quantity and quality of greenhouse lettuce cv. grate lake 118 this experiment was carried out based on a completely randomized design of four replications. the treatments were different mixture...

soilless culture of greenhouse vegetables has been a fast developing section in iran during recent years. most growers fertigate plants without enough knowledge about plant water requirements. since some soilless substrates have low water retention capacity, wasting a great amount of nutrient solution can be occurred due to poor management. in this research work, effects of hydro gel amendment ...

Wholesale container-grown ornamentals are often maintained at the nursery for at least two growing seasons and are subject to infestation by black vine weevil (BVW), Otiorhynchus sulcatus F., for several months each year. Therefore, a potting media amendment aimed at controlling BVW needs to persist for an extended period of time. These studies were conducted to determine the persistence and ec...

Food plants biofortification for micronutrients is a tool for the nutritional value improvement of food. Soilless cultivation systems, with the optimal control of plant nutrition, represent a potential effective technique to increase the beneficial element content in plant tissues. Silicon (Si), which proper intake is recently recommended for its beneficial effects on bone health, presents good...


 Kebutuhan padi fungsional terus meningkat di Indonesia, namun luas lahan budidayanya semakin berkurang. Oleh karena itu, perlu adanya upaya untuk meningkatkan produksi fungsional, salah satunya melalui budidaya soilless. Penelitian ini bertujuan mengkaji pertumbuhan dan hasil tiga varietas yang dibudidayakan pada media soilless (air sekam). Percobaan dilakukan menggunakan rancangan acak ...

The objective of this work was to optimize a soilless growing system for producing bare-root strawberry transplants in three organic substrates. Three trials were conducted in the Quebec City area to determine the productivity potential of a peat-sawdust mixture (PS25) and an aged bark (AB) material compared to conventional coconut fiber (CF) substrate. A first experiment was carried out to def...
