Field studies were carried out to evaluate the effect of sowing time and spacing on the growth and fruit yield of okra in 1999 and 2000 in the farmer = s field, Lakshmipur, Bangladesh. The highest plant height was recorded 87.5 cm when okra was sown on 5 March, 2000 at the spacing of 45 x 45 cm and the lowest height was 73.3 cm when okra was sown on 20 May, 1999 at the spacing of 35 x 40 cm. The maximum number of leaves per plant was observed when it was sown on 5 March 2000 and the minimum was when sown on 20 May, 1999. Moreover, the fruit yield, number of fruit picking per plant, fruit length and weight per fruit were higher when okra was sown on 5 March, 5 April and 5 May, 2000 spaced at 45 x 45 cm than when okra was sown on 20 March, 20 April and 20 May, 1999 spaced at 35 x 40 cm. The highest number of percent mosaic infected plant was counted when okra was sown on 20 May, 1999 at the spacing of 35 x 40 cm and the lowest was when okra was sown on 5 March, 2000 at the spacing of 45 x 45 cm. In addition to that the highest number of vector of okra mosaic disease was counted when okra was sown on 20 May, 1999 at the spacing of 35 x 40 cm and the lowest was when okra was sown on 5 March, 2000 at the spacing of 45 x 45 cm. Percent mosaic infected plants was highest in 1999 and the lowest was in 2000 when it was sown on 20 May and 5 March due to the presence of the number of vectors of okra mosaic disease.
