Four levels of Nitrogen (N) as 140, 160 and 180 kg N ha-1 as urea super granules (USG) and 180 kg N ha-1 as prilled urea (PU) as well as three different organic nitrogen sources (IPNS based) were considered to comprise 24 treatments combinations. The experiment was laid out in a randomized complete block design with three replications. USG along with organic manures showed better yield performance regarding yield attributes and yield compared to PU. The highest head yield (14.7 t ha-1) was found in USG-N160 kg/ha+ Oil Cake (OC)2t/ha followed by USG-N180kg/ha+ OC2t/ha (14.5 t ha-1). The maximum lateral head yield (6.612 t ha-1), marginal rate of return (132), and benefit cost ratio (4.00) were recorded in USG-N160kg/ha+ Poultry manure (PM)3t/ha. The treatment PU-N180+PM3 also showed better performance regarding yield (13.7 t ha-1), harvest index (27.1%) and benefit cost ratio (BCR) (3.84). Therefore, USG @160 kg N ha-1 + 3 t ha-1 poultry manure as adjusted N126P22K62S14Zn2B1Mo0.8 kg/ha+3 t/ha PM or PU @180 kg N/ha + 3 t/ha poultry manure as adjusted N146P22K62S14Zn2B1Mo0.8 kg/ha+3 t/ha PM can be recommended for broccoli production in Grey Terrace Soil. |
