EFFECT OF PLANTING TIME AND ORGANIC MANURE ON GROWTH AND YIELD OF BROCCOLI

Abstract

The study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2011 to March 2012. The experiment consisted of two factors: Factor A: Planting time (three levels) as T 1 : Planting at 13 November, 2011; T : Planting at 23 November, 2011; T 3 M 2 : Planting at 03 December, 2011 and Factor B: Organic manure (four levels) as 0 : Control i.e. no manure application; M 1 : Cowdung @ 15 t/ha; M : Poultry Manure @ 12 t/ha and M : Vermicompost @ 13 t/ha. The experiment was laid out with Randomized Complete Block Design with three replications. In planting time, the highest weight of primary curd per plant (427.8 g) and highest yield (10.6 t/ha) was recorded from T 3 , while the lowest (404.2 g) and (9.91 t/ha) from T 3 2 . For organic manure, the highest weight of primary curd per plant (484.7 g) and highest yield (12.0 t/ha) was recorded from M , while the lowest (253.9 g) and (6.45 t/ha) from M 0 2 . Due to the interaction effect, the highest weight of primary curd per plant (532.3 g) and highest yield (13.4 t/ha) was recorded from T 2 M 2 and the lowest (236.8 g) and (6.68 t/ha) from T 1 M . The highest benefit cost ratio (2.31) was noted from T 2 M 2 0 and the lowest (1.26) from T 1 M . So, planting at 23 November with poultry manure was better for the broccoli production.
