Abstract:
Broccoli (Brassica oleracea var. italica L.), is an important cole crop with high nutritional value gaining popularity in metropolitan cities of Telangana state. Considering the inadequacy of information regarding the nutrient requirement of exotic vegetable broccoli through fertigation, the present study was aimed to standardize the appropriate fertigation schedule, thereby providing highly nutritive non-native vegetables to the farmers of our state. The experiment was conducted for two years (Rabi 2019-20 & 2020-21) which was laid out in randomized block design with five treatments viz (60% RDF, 80% RDF, 100% RDF, 120% RDF along with control) and four replications. Significant difference was observed among the treatments with respect to growth and yield parameters. The pooled data revealed that, among 5 treatments maximum yield per ha was recorded in T₄ -120% RDF (222.27 q/ha) which was on par with the treatments T₃ -100% (214.68 q/ha) & T₂ -80% (210.03 q/ha). However, the highest B:C ratio (1:4.70) was observed in treatment T₂ -80% RDF (160-100-100 NPK kg/ha) through drip irrigation by using fertilizers like Urea (276 kg/ha), 75% P applied as basal through SSP (468 kg/ha), water soluble fertilizers 12-61-0 - MAP (41 kg/ha) & 13-0-46 –KNO₃ (225 kg/ha) in 17 splits at 5 days interval. Among the treatments studied, T₂ -80% RDF gave a similar yields as 100% RDF and 120% RDF and highest B:C ratio of 1:4.70 with 20% fertilizer saving without affecting growth and yield parameters.
