Abstract

Tomato (Solunum lycopersicon L.) which belongs to solanaceae family is the second most important vegetable in Kenya. The objective of this study was to determine the effects of Bunching onion (Allium fistulosum) crude extract concentrations and irrigation levels on growth and yield of tomato. Greenhouse experiment was conducted n a completely randomized design (CRD) with three replications and employed a single factor treatment design with combinations of different levels of Allium fistulosum crude extract and different levels of irrigation treated as distinct treatments. The treatments consisted of combinations of Allium fistulosum at 20% and 15% with levels of irrigation at 0.5 l, 1 l, 1.5 l and 2 l/pot/week and negative and positive control (green cop) combined with 2 l/pot/week. The results from the study showed that tallest plants and thickest stems were obtained under 20% combined with 2 l and 1.5 l of water. Tomato plants flowered early when treated with under 20% diluted in 1 l of water treatment. Highest number of tomato fruits and fruit weight were obtained under 20% combined with 2 l of water while the lowest number of fruits and fruit weight were obtained under the negative control treatment. From this study Allium fistulosum crude extract in combination with irrigation levels improved tomato growth and yield. It was clear that, concentration 20% of Allium fistulosum crude extract combined with in 2 l of water improved tomato growth and yield.
