| dc.description.abstract | Abstract :
A field experiment was conducted at the Tuber Crops Research Centre (TCRC)
A arm, Bangladesh Agricultural Research Institute (BARI), Gazipur during the period from December 2006 to March 2007 in order to quantity the effect of dfierent organic manures and fertilizers viz. cowdung, poultry manure, mustard «•'.] cake, farm yard manure, NPK fertilizers, and some Bangladeshi trade named • rganic manures like Northern balanced fertilizer, Northern compost, Northern •anic fertilizer (Jaibo sar), and Chook Chook on the growth and yield of potato Diamant. The experiment consisting of 10 treatments was laid out in the randomized complete block design with 4 replications. Organic manures had significant influence on growth, yield contributing characters and yield of potato.
Results revealed that days required to 80% emergence of seedling, plant height, foliage coverage, number of stems per hill, days required to 80-90% senescence of leaves, weight of tubers per hill, number of tubers per hill, dry matter content of tubers, marketable yield (21.28 ton/ha) and gross yield (23.68 ton/ha) of tubers were the highest when Northern organic fertilizer was applied in combination with the recommendation dose of NPK treatments. The best economic return was also recorded in the same treatment showing a benefit cost ratio of 2.68.
