Abstract
The effect of sowing date (three sowing dates viz., S1= 01 November, S2= 15 November and S3= 30 November) and phosphorus levels (four phosphorus fertilizer levels viz., P0= Control, P1= 35 kg P ha-1, P2= 45 kg P ha-1 and P3= 55 kg P ha-1) on growth, seed yield and quality of fenugreek was investigated at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, during 10 October 2020 to April 2021. Growth-related data was maximum on S1 (01 November) treatment but S2 (15 November) treatment showed the best result in case of seed yield. In case of growth characters, P3 (55 kg ha-1) revealed the best result but in case of seed yield, P2 (45 kg ha-1) treatment showed the best effect. Under this investigation, it was revealed that the maximum growth was obtained by S1P3 (01 November with 55 kg P ha-1) and the minimum growth was obtained by S3P0 (30 November with control) treatment combination. The maximum pods per plant (52.61), seeds per pod (12.87), weight of individual pod (147.11 mg), the weight of seeds per plant (7.67 g) and weight of 1000-seed (13.86 g), seed yield per plot (306.72 g), seed yield per hectare (2.13 t) and vigor index (570.27) was observed from the treatment combination S2P2 (15 November with 45 kg P ha-1). It was concluded that the combination of sowing date S2 (15 November) along with phosphorus application P2 (45 kg P ha-1) were given the better performance of all the yield contributing parameters and seed yield of fenugreek. So, S2P2 (15 November with 45 kg P ha-1) treatment combination can be repeated in different agro-ecological zones of Bangladesh.
