Abstract
The present investigation entitled, "Studies to standardize fertilizer dose for broccoli {Brass¡ca oleracea var italica) under tropical conditions of Pune", was carried out at Vegetable Research Unit, National Agricultural Research Project, Regional Fruit Research Station, Ganeshkhind, Pune during rabi season of the year 2000. The experiment was laid out in the Randomized Block Design with twelve treatments namely, 75+20+20, 75+40+40, 100+25+25, 100+50+50, 125+30+30, 125+60+60, 150+30+30, 150+60+60, 175+30+30, 175+60+60, 200+35+35 and 200+70+70 NPK kg/ha, respectively, and replicated three times. Urea, single superphosphate and murate of potash were used as the sources of nitrogen, phosphorous and potassium, respectively. All the phosphorous and potash, and half of the nitrogen were given at the time of transplanting while remaining half nitrogen given after one month. Along with this, FYM @ 10 tonnes per hectare was applied to all the treatments, at the time of preparatory tillage. The growth parameters viz. plant height, plant weight, leaf length, curd diameter and curd weight significantly different due to fertilizer doses. The highest yield was obtained with a fertilizer dose of 175+30+30 NPK kg/ha. The earlier curd initiation and short crop duration was observed with middle level of fertilizer doses (125+30+30, 125+60+60, 150+30+30 and 150+60+60 NPK kg/ha, respectively). At lower level of fertilizer dose, a slight purplish tinge or pigmentation was observed on the curds, which was not desirable. Curd colour was dark green in all the remaining treatments. The incidence of the "hollow stem disorder" was favoured by the higher fertilizer doses, and nitrogen played a major role. Shelf life of broccoli curds was better with 175+30+30, 150+30+30, 125+30+30 NPK kg/ha.
