Responses of Agronomic Parameters of Tomato Seedlings to pH Level and Shade

Abstract

This study was carried out to evaluate responses of tomato (Lycopersicon esculentus) seedlings to shade and different pH  levels. The experiment was arranged in completely randomized design (CRD) of 4 replicates per treatment. Agronomic data such as plant height, number of leaf, stem girth, leaf area, fresh and dry weight of roots, shoots and chlorophyll contents of the tomatoes were determined. The data were subjected to analysis of variance (ANOVA) of statistical analysis system (SAS) Institute, 1999. Means were separated by Duncans Multiple Range test (DMRT) at P < 0.05. Results of the study revealed that highest tomato height (21.50 cm), number of leaf (24.52) and leaf area (3.59 cm²), fresh weight (5.67 kg), root dry weight (0.74 kg) and chlorophyll content (0.19) were recorded in tomato treated with pH 9 and shade.

Key words: Agronomic parameters, chlorophyll, pH level, tomato seedlings and shade.   REFERENCES
