Abstract
A pot experiment was carried out at the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh, during the period from November 2006 to March 2007 to study the effect of different levels of phosphorus (0, 40, 60 and 80 kg ha-1) on growth and yield of three tomato genotypes (CLN-2026, BINA tomato-4 and BINA tomato5). Results revealed that morphological growth, yield contributing characters and fruit yield were significantly influenced by different levels of phosphorus. Plant height, branch number, leaf number, fruit cluster number and fruit number plant-1 increased with increasing phosphorus levels up to 80 kg ha-1, but from the economic point of view, 60 kg ha-1 was the best for the fruit yield (2.83 kg ha-1). However, among the genotypes, BINAtomato- 4 and BINAtomato -5 (2.4 kg ha-1) performed well in respect of growth, yield contributing characters and fruit yield.
