Abstract

Tomato (Lycopersicon esculentum); a member of the family Solanacea is a commercially important vegetable throughout the world both for the fresh fruit market and food industries. The research was carried out in the green house at Science Laboratory Technology of the Oke-Ogun Polytechnic, Saki, Oyo State. Improved dry seeds of tomato (Lycopersicon esculentum) was obtained from the Institute of Agriculture Research, (I.A.R&T), Ibadan, Oyo State and were subsequently treated with Sodium Azide aimed at determining the effects of Sodium Azide as a known mutagen on tomato grown with organic and inorganic fertilizer. All the parameters were monitored for six-months with everyday documentation of variants (variables). Highly significant differences were observed in the treatments with respect to the studied parameters (seed germination, seedling survival, seedling height, root length, number of leaves per seedlings, height at maturity, number of branches per plant and fruits per plant) and various chemicals found in the soil sample. Treatment and chemical interactions were similarly highly significant in tomato with Sodium Azide and organic fertilizer with respect to all parameters evaluated and the chemical composition showed better performance compared to tomato seeds grown with inorganic fertilizer. Conversely, Sodium Azide could be utilized as an induced of variability for the improvement of tomato likewise organic fertilizers

Highlights

Tomato (Lycopersicon esculentum) which belong to the family Solanacea is a commercially important vegetable throughout the world both for the fresh fruit market and food industries
The research was conducted in the Green House of the Science Laboratory Technology in The Oke Ogun Polytechnic, Saki, Oyo State which is located 8o40’N 3o24’E and it is situated at elevation 472 meters above sea level
The decrease in seedling emergence, seedling height, root length, and seedling survival, height at maturity and fruit yield per plant with increasing mutagen concentration has been reported in mutagenesis studies [11] when groundnut was treated with gamma rays

Summary

Introduction

Tomato (Lycopersicon esculentum) which belong to the family Solanacea is a commercially important vegetable throughout the world both for the fresh fruit market and food industries. Tomato is considered one of the most valuable horticultural crops, because of its economic importance, and for its sensory qualities and nutritional value. It is usually in the form of fresh as well as processed products for consumption. Tomato is one of the food crops with the potential to provide vitamins, calcium, protein and agrobased raw materials for the ever increasing global population [3, 4].
