Effect of Root Restriction on the Performance of Three-Truss Cultivated Tomato in the Low-Node Pinching Order at High-Density Cultivation System

The low-node pinching order at a high-density plant cultivation system (LN&HD) is now widely adopted for increasing tomato yield and fruit quality. LN&HD period spans 70–120 days, employs the use of small amount substrate (low volume), plants are usually topped between first fourth truss. Using in induces root restriction. Increasing extent restriction pots has been quality some advanced countries. However, improving expense becomes major drawback adopting Ghana. was introduced into Ghana mainly to increase sustainably cost-effective level. This study aimed manipulate or reduce yield. Information related manipulating reducing not extensively reported. Thus, an experiment conducted (between 21 April 2019 11 August 2019) greenhouse University Forest Horticultural Research Centre, Kade-Ghana. Plants two cultivars (Jaguar Momotaro York) were subjected four conditions. (1) complete 1.0 L volume capacity pot, (2) 1.5 (3) partial Rockwool-like cultivation, otherwise referred as Cocowool, (4) No trough containing substrate. laid out 2 x 4 factorial randomized block. Results showed that Cocowool unrestricted roots produced highest total dry matter compared received restrictions pots. tomato’s soluble solids increased with pot. Reducing tomato. With LN&HD, could be used (at reduced cost) tropical grown
