NUTRIENT MANAGEMENT OF BRAHMI (BACOPA MONNIERI L.) CULTIVARS IN SOIL AND COMPARISON WITH HYDROPONICALLY GROWN PLANTS FOR BETTER HERBAGE YIELDAgumjot Kaur, Gurbax Singh Chhina and Puneet Kaur
A field experiment was conducted during kharif season of 2019-20 at Department of Agriculture, Khalsa College, Amritsar. It consisted of 10 treatment combinations which included two cultivars (CIM-Jagriti and Subodhak) and five nutrient management, viz. Vermicompost 10 t ha-1, FYM 20 t ha-1, Vermicompost 5 t ha-1+ FYM 10 t ha-1, Recommended dose of NPK fertilizers 100: 60: 50 kg ha-1 and Hydroponics (half-strength Hoagland solution). The results revealed that cv. Subodhak had produced more yield than cv. CIM-Jagriti but bacoside-A content was higher in the latter (16 percent higher). Among nutrient management, Brahmi grown in hydroponics (half-strength Hoagland solution) had significantly higher growth and yield attributes (viz. main shoot length, number of shoots, number of leaves, leaf area, fresh and dry weight) while FYM 20 t ha-1 recorded lowest growth and yield. Additionally, hydroponically grown brahmi had 7.5 percent more bacoside-A content than soil grown brahmi.
