The development of a soilless crop culture system based upon the Nutrient Film Technique (NFT) was studied. The conventional polythene gullies used for the NFT in temperate regions were found not ~uitablefor .the ho! tropical -climate. An insulated NFT shallow trough desz~n was effective in controllzng heat buzld up In the root zone. Muskmelon, vegetables and ornamental plants were successfully...

The requirement to phase-out methyl bromide (MB) in the cut-flower sector needs more attention than in other sectors in order to identify fully effective solutions that are environmental friendly and technically sustainable. Resistant varieties, soilless cultivation, steam, soil solarization, biocontrol agents and chemicals have been evaluated as potential alternatives and can be considered as ...

Although we normally think about soilless culture as a modern practice, growing plants in containers aboveground has been tried at various times throughout the ages. The Egyptians did it almost 4000 years ago. Wall paintings found in the temple of Deir el Bahari (Naville 1913) showed what appears to be the first documented case of container-grown plants (Fig. 1.1). They were used to transfer ma...

Sewage sludge ash (SSA) as a secondary phosphorus (P) source may help to conserve global rock phosphate deposits if used in the base fertilization of soilless growing media. Plant availability SSA-P was studied pot experiment with marigolds peat-based medium contrasting pH (4.5, 6.0). Six SSAs were included study and compared water-soluble monocalcium (MCP) (RockP). In addition efficacy SSA-P, ...

This experiment was conducted to study the effect of cocopeat: perlite medium with three ratios (v/v) (1:1, 3:1 and 1:3) on some vegetative, flowering and biochemical parameters of two gladiolus cultivars (Strong and White) under soilless conditions in 2016. Data indicated that most vegetative parameters expressed as plant height, leaf number and leaf area, flowering parameter such as spike eme...

Abstract Cocoa ( Theobroma cacao ) seedlings are very sensitive to water stress during the nursery stage and early field establishment. Sawdust, carbonated rice husk, compost in following ratios (i) 60: 40: 0 – M1, (ii) 30: 10 M2, (iii) 20: 20 M3, (iv) 10: 30 M4, (v) 0: 40 M5, (vi) topsoil M6 as control were used investigate effect of growing media, stress, re-watering on growth, dry matter pro...
