This research work was conducted at District Layyah to evaluate the impact of ecoclimatic conditions, soils texture on growth parameters and nutritional values of three tomato varieties. The tested varieties were DT97/162A(R), DT97/215.A, local V1 and local V2. They were assigned randomly into different blocks in the fields as completely randomized block design (RBCD). In present results, physio-chemical properties of soil, nutritional values and morphometric characteristics of three tomato varieties were analyzed and documented. The pH 7.6 was measured. Available Phosphorus was calculated as 7.8 mg/kg. Total Nitrogen appeared in collected samples was 0.6%. Ca2+ indicated maximum exchangeable cation (2.9 mg/g) as comparison to other cations. In exchangeable acidity, Fe (ppm) indicated highest value (19.4 meg/100g). Maximum (42.55%) protein percentage produced by local variety V2 while highest (41.50%) fat shown by variety DT97/162A(R). Fiber percentage appeared almost similar in all analyzed varieties. Vitamin C (0.37 mg/100g) was measured highest in local variety V2. The highest values of Ca (0.395%), Mg (0.215%), K (0.182%) and P (0.572%) were also observed in tomato local variety V2. However, tomato variety local V2 showed higher plant height. Tomato variety DT97/162A(R) showed highest number of leaves while DT97/215A indicated minimum values. Number of flowers and number of fruits were produced almost similar in all varieties. Hence, local variety V2 showed highest growth, better yield performance and high nutritional values. Therefore, it is concluded that a local variety (V2) suggested as the suitable tomato variety for the environmental conditions of District Layyah, Pakistan.
