Abstract
A Study was conducted to investigate the effect of integrated nutrient management on growth, yield and quality of crossandra (Crossandra undulaefolia Salisb.) hybrid Arka Ambara was carried out in the Department of Horticulture, UAS, GKVK, Bengaluru. Application of 100 per cent recommended dose of nitrogen, phosphorus and potassium + Azotobacter + PSB + KSB had significantly improved plant
height (19.67, 32.00, 37.20, 43.29, 50.07 cm), number of branches per plant (3.83, 6.16,10.50, 12.67, 16.20), plant spread (575.6, 731, 1234,1442, 2111 cm2) at 30,60,90,120 and 150 days, respectively. Also with reference to flower parameters viz., days taken to first spike initiation (85.03 days), number of spikes per plant (45.67) and flower yield (4.22 t/ha) were found significantly higher value compared to control (100 per cent RDF). Treatment with 75 per cent recommended dose of nitrogen, phosphorus
and potassium + Azotobacter + PSB + KSB showed on par results. The maximum microbial count of fungi (22.68x103cfug-1), bacteria (59.33x106cfug-1), actinomycetes (15.68x104cfug-1) were recorded. The maximum shelf life (47.33 hours), highest net returns (Rs. 1778476/-) and highest cost: benefit ratio (2.36) were recorded in treatment which received 100 per cent recommended dose of nitrogen, phosphorus and potassium + Azotobacter + PSB + KSB.
