Nutrient Uptake and Soil Nutrient Status as Influenced by Drip Fertigation Levels and Schedules in Broccoli

The experiment was carried out to study the effect of fertigation levels and schedules on growth and yield of broccoli (Brassica oleracea var italica) during the rabi season of 2021-22 involving 4 levels of fertilizer (75, 100 and 125 % RDF) along with one control (100 % RDF) through soil application and three fertigation scheduling (S1, S2 and S3) with three replications. The result of study revealed that higher fertigation of broccoli with balanced nutrition; better water and nutrient utilization gave significantly higher plant growth and yield and good quality of broccoli. In general, pooled mean revealed that application of 125 % RDF with fertigation schedule S2 :15 % NPK at transplanting to plant establishment, 1-10 DAT, 50 % NPK at curd initiation stage,11-35 DAT and 35 % NPK at curd development stage, 36-60 DAT recorded maximum NPK uptake in plant (kg/ha) and available NPK in soil (kg/ha).
