Abstract
The present study was conducted at the Research farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during March to June 2014 to examine the effect of Phosphorus on the growth and yield of Sesame. BARI Til-3 variety was used for the study. This experiment was consisted of single factor eg. phosphorus. There were three levels of phosphorus viz. (i) P0 (0 % P), (ii) P1 (20 % P) and (iii) P2 (30 % P) and the experiment was laid out in a Randomized Complete Block Design (RCBD) with six replications. Different levels of phosphorus showed significant effect on growth and yield of sesame. Individually phosphorus had significant effect on highest plant height, number of leaves plant-1, number of primary branches plant-1, number of secondary branches plant-1, number of capsule plant-1, number of seeds capsule-1, 1000 seed weight, seed yield and harvest index. The highest plant height of sesame (136.30 cm), the highest no leaves plant-1 of sesame (34.44), number of primary branches plant-1 (5.56), number of secondary branches plant-1 (7.61), number of capsule plant-1 (25.87), number of seed capsule-1 (70.47),1000 seed weight (3.54), Seed yield (1581.00 kg ha-1), Stover yield (3034.42 kg ha-1), biological yield (4615.76), harvest index (34.11%), oil content (43.92%) was recorded from P1. Again, the highest days to first flowering of sesame (31.67) was recorded from P1 (20 % P) but the highest days to maturity was (85.67) recorded from P2 (30% P). Application of P at different percentage is causing effect in growth and yield of sesame.

Highlights
Sesame (Sesamum indicum L.) commonly known as TIL is one of the oldest cultivated plants in the world and indigenous oil plant with longest history in India sub-continent
Similar result was found from the findings of Jadhav et al (1992) and they stated that plant height of sesame was increased up to 40 kg P2O5 ha-1 and it was on par with 60 kg P2O5 ha-1 which result was supported by Kathiresan (1999) and Haruna et al (2010)
Yield contributing characters Significant variation was found with different levels of phosphorus on number of capsule plant-1 of sesame at 95 days after sowing (DAS)
Summary
Sesame (Sesamum indicum L.) commonly known as TIL is one of the oldest cultivated plants in the world and indigenous oil plant with longest history in India sub-continent. It is used as oil seed and local preparation of weaning food (Abdel, 2008) Despite of being such an important crop, the productivity of sesame in Bangladesh is very low (889 kg/ha) in comparison to global level (Anonymous, 1996). It is quality food, nutritious, edible oil, biomedicine and health care all in one. Sesame is grown mainly for seeds that contain 42-50% oil, 20% protein 5.3% water, 5.2% minerals, 2.9% fiber and 25% carbohydrate per 100g edible portion (Burden, 2005) It is called as “Queen of Oilseeds” as it contains good quality poly-unsaturated fatty acids viz., 47% oleic and 39% linoleic acid. Considering the said facts into deliberation, a field trial in sesame was conducted consecutively to find out the effect of Phosphorus (P) on different growth and yield parameter of sesame
