Abstract
The study was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from May 2014 to February, 2015. The experiment consisted with two factors. Factor A- Five levels nutrient sources: F0 - Control, F1 - Cowdung 10 t + 250 kg Urea + 190 kg TSP + 190 kg MP/ha, F2 - Poultry litter 5 t + 250 kg Urea + 190 kg TSP + 190 kg MP/ha, F3 - Cowdung: 15 t/ha and F4 - Poultry litter: 10 t/ha; Factor B: Three levels of mulch: M0 - control, M1 -Rice straw mulch and M2 - water hyacinth mulch. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Application of fertilizer with different mulches showed significant variations on most of the parameters. The highest yield of spike (3,69,290 /ha) was found from F1M2 and the lowest (2,90,760 /ha) from F0M0. The maximum yield of bulb per hectare (31.83 ton) was observed in F1M2 and the minimum (12.21 ton) was recorded from F0M0. The maximum yield of bulblet per hectare (27.12 ton) was observed from F1M2 and the minimum yield (12.85 ton) was observed from F0M0. So, application of cowdung 10 t + 250 kg Urea + 190 kg TSP + 190 kg MP per hectare with water hyacinth mulch was found suitable for growth and yield of tuberose.
