Abstract
Two long-season tomato crops ( Lycopersicon esculentum Mill. cv. Trust; in 1996 and 1997) were grown in an open rockwool system (conventional culture method) and in closed rockwool culture systems with different nutrient feedings to develop a closed tomato production system with zero discharge of nutrient solutions to the environment. The tomato grown in the closed rockwool systems with a modified rockwool or nutrient film technique (NFT) feeding formula achieved similar marketable yield as the tomato grown in the conventional open rockwool system. Similarly, there were no differences in early plant growth and photosynthesis, total plant biomass and biomass partitioning, fruit yield, or fruit size and grades. The tomato plants grown in the closed rockwool systems senesced slower, as demonstrated by higher photosynthesis in old leaves, and had better root systems than the plants grown in the conventional open rockwool system. The fruit quality of tomato produced in the closed rockwool systems was better than that of tomato produced in the open rockwool system in one of two crops. These results demonstrated that the closed rockwool system with optimized nutrient feeding is an economically and environmentally sound alternative to the conventional open rockwool production method.
