PERFORMANCE OF DIFFERENT VARIETIES AND FERTILIZER MANAGEMENT PRACTICES ON THE GROWTH AND YIELD OF KNOL-KHOL

Abstract

A heW experiment was carried out to investigate the perlormance of ditterent varieties and different fertilizer management practices on the growth and yield of Knol-khol at the Horticulture farm of Sher-c-Bangla Agricultural University. Dhaka during the period from October, 2007 to January, 2008. The experiment consisted of five varieties, viz. V,: White vienna: V2: Quick star; V 3: Sufala-14; V 4 : tWO: V ç: Early 005 and Ibur kinds of fertilizer management practices, viz. F0 : Control; F 1 : Organic Manure; F 2 : Inorganic fertilizer; F3: Organic fertilizer Inorganic fertilizer. The experiment was carried out in randomized complete block design with three replications. Both variety and fertilizer management practices had significant influence on growth and yield, in case of varieties. V 1 showed highest marketable yield (29.39 t/ha) and V 5 the lowest (22.43 t/ha). For fertilizer, the maximum marketable yield (31.78 t/ha) was found in F 3 and the lowest (18.99 t/ha) in F 0. For combined effect, the highest marketable yield (37.51 t/ha) was obtained from V 1 F 3 and the lowest (16.31 t/ha) from V 5F 0 . Maximum net return (200730.62 11./ha) and benefit cost ratio (3.02) were thund from V 1 F 3 and the lowest from V,F 0 . So. highcr yield could be obtained by cultivating the Vhite vienna of Knol-khol with both organic and inorganic fertilizers under the Madhupur tract of Bangladesh.
