Smoke-water foliar spray has been reported to promote seedling growth (Kulkarni et al., 2007) and yield of tomato under greenhouse experiment (Kulkarni et al., 2008). However, the application of smoke in the form of WV, in combination of FB, has not been well researched in tomato. In this study, the efficacy of these two natural products on growth and yield of tomato c.v. Delta was investigated when applied as foliar spray and soil drench in pot and field experiments.
Two fertilizer application rates were used in an attempt to elucidate whether WV and FB can partially substitute the use of
chemical fertilizer.
