“…Delgado in gunny bags containing perlite, rockwool, or coconut fiber with a supply of diverse nutrient solution through a drip channel in a polyhouse showed that the maximum yield of F1 hybrid tomato cultivar was obtained in coconut fiber and the best fruit quality was found in perlite growing media . The substrate or growing media determines the water use efficiency, nutrient use efficiency, and yield of the crop . Successful cultivation of vegetables and ornamental plants in hydroponic systems using different substrates and nutrient solutions have been reported: for example, carrot in rockwool blocks containing vermiculite with a supply of nutrient solutions through subsurface irrigation in a greenhouse, watermelon grown in aeroponics by NFT, lettuce raised in polystyrene foam + pots with discharge of three nutrient solutions through a floating system in a greenhouse, ginger in pots supplemented coir dust and burnt paddy husk in different proportions with MARDI nutrient solution through irrigation channels in a side-netted rain shelter, green beans in pots supplemented with peat, perlite, and sand with a supply of nutrient solution through subsurface irrigation, broccoli grown in rockwool with supply of Hoagland nutrient solution in a multitunnel greenhouse, kohlrabi ( Brassica oleracea var.…”

Soilless culture is emerging as a popular tool to grow agricultural and horticultural crops in open systems, closed systems, protected cultivation, vertical farming, and soil affected or stress-affected areas. The climatic factors and biometabolism are integrated in stimulating quality phenological growth and biochemical and physiological processes in soilless crop production. Soilless crop production (SCP) has immense potential to build a soilless green revolution and for sustaining crop production. Information on substrate and water based culture collected for the period from 1996 to 2022 is reviewed and analyzed in this work. The performance of crops in soilless culture improves morphological and physiological parameters compared with soil based cultivation. The distinct environmental factors positively influence soilless culture to exhibit cellular processes, biological processes, molecular processes, and the ecosystem in the crop. The impacts of ecological factors are more efficient in closed systems compared with open systems. The salient features of metabolites and biometabolism in substrate based media were identified with transcriptome analysis and found to be different compared with soil based cultivation. Developing simple nutrient formulations suited for soilless culture is essential to popularize this technology among marginal farmers.

“…A reduction in the size of the root zone volume lowers the buffering capacity of root environment and requires more stringent management of the system parameters (Van Noordwijk, 1990 ). Under such conditions, fine-tuning system parameters such as physical shape of the stone wool slab and dripper positions may significantly impact the root-zone environment and yield responses (De Rijck and Schrevens, 1998 ; Bar-yosef, 2008 ; Saiful Islam et al, 2008 ). Indeed, previous studies have analyzed the effects of stone-wool system parameters on the hydraulic properties of the stone wool substrate (Bougoul et al, 2005 ; Bougoul and Boulard, 2006 ).…”

Standardized cultivation systems are crucial for establishing reproducible agronomic techniques. Especially stone wool-based cultivation is governed by standardized specifications and provides a controllable root-zone environment. However, the effects of stone wool cover incision on root-zone variability have rarely been studied. Therefore, in this study, we focused on the effect of the stone wool cover incision method on environmental variations and their subsequent effects on tomato plant productivity. Stone wool slab plastic covers represent a core component of this substrate system that can potentially affect the performance of water control techniques. We designed a cover incision method to create four different levels of drainage performances that were tested by cultivating tomato plants (Solanum lycopersicum “Dafnis”). The water content, root-zone temperature, and dissolved oxygen were measured and analyzed relative to the tomato yield. We found that the incision level with the lowest drainage performance showed a lower air-root zone temperature correlation slope than those of slabs with favorable drainage conditions. Furthermore, these slabs had low dissolved oxygen levels (3.2 mg/L); nevertheless, the tomatoes grown in the slabs with incision level showing the lowest drainage performance had greater fruit yield (6,748 g/plant) than those in the slabs with favorable drainage conditions (6,160 g/plant). Furthermore, the normalized yield separation timing between treatments coincided with the hotter air temperature (27°C average) periods. We noted that manipulating the cover incision process consequently entailed variations in the correlation slope between the air temperature and root-zone temperature in the substrate. Our results reveal another trade-off relationship in the conventional perspective on the drainage performance effects and provide insights into further optimization of crop production and water use in the stone wool-based system.
