Abstract
Due to the high cost of tomato seeds, it is important to fully exploit the seeds for economic gains. This has necessitated the use of vine cutting technology in tomato production from vegetative parts. However, the vine acclimatization substrates type plays important role in the survival of the cut vines. Hence, this study investigates three different substrate types (cocopeat, water and loamy soil) for their suitability for vines cutting. Seeds of three tomato genotypes were raised in hydroponics system containing dissolved cocopeat. At one month after planting, vines were cut from the plants into the three substrates in a Completely Randomized Design with three replicates. Data were collected on vine survival, days to new shoot formation, number of fruits per plant and the average fruit weight at harvest. Data collected were analyzed using ANOVA and differences in the treatment means were separated using the Least Significant Differences at 5 % level of significance. Results obtained showed that the percentage vine survival across the substrates was insignificant with a success rate of up to 77 % in the loamy soil. However, new shoot formation was fastest in the cocopeat substrate (12.56±0.53), while San marzano had the heaviest fruit size (20.73±1.33).

IntroductionBackground Information Tomato (Solanum lycopersicum L.) is an important vegetable that has gained much recognition because of its economic (Nasir et al, 2015) and nutritive properties in terms of protein, carbohydrate, vitamins etc (Vinha et al, 2014)
Background Information Tomato (Solanum lycopersicum L.) is an important vegetable that has gained much recognition because of its economic (Nasir et al, 2015) and nutritive properties in terms of protein, carbohydrate, vitamins etc (Vinha et al, 2014). The downside of this worldwide recognition is reflected in the high cost of tomato seeds which is usual means of its cultivation, as many farmers are interested in the production, which has placed more pressure in the demand for seeds for planting (Heder et al, 2010)
Tomato plants are usually cultivated through the zygotic seeds, it can be propagated through the vegetative parts (Ossai et al, 2020)
Summary
Background Information Tomato (Solanum lycopersicum L.) is an important vegetable that has gained much recognition because of its economic (Nasir et al, 2015) and nutritive properties in terms of protein, carbohydrate, vitamins etc (Vinha et al, 2014). The downside of this worldwide recognition is reflected in the high cost of tomato seeds which is usual means of its cultivation, as many farmers are interested in the production, which has placed more pressure in the demand for seeds for planting (Heder et al, 2010). Tomato plants are usually cultivated through the zygotic seeds, it can be propagated through the vegetative parts (vine cutting technology) (Ossai et al, 2020). Reports on the vine cutting technology system of propagating tomato are limited to the use of cocopeat substrate (Suvo et al, 2016; Ossai et al, 2020).
