EFFECT OF NANO FERTILIZERS ON GROWTH AND YIELD OF ASPARAGUS DENSIFLORUS CV. SPRENGERI

The experiment was designed to study the effect of nano fertilizers on growth and yield of Asparagus densiflorus cv.'sprengeri'.The experiment comprised of 12 treatments using two nano fertilizers viz., Nano NPK 4:4:4 soil drenches @ 1500 ppm, 3000 ppm, 4500 ppm and nano urea foliar spray @ 0.05 %, 0.1 % along with control (water spray).The experiment was laid out in completely randomized design (CRD) with three replications.The treatment with nano NPK 4:4:4 soil drenches @ 4500 ppm + nano urea foliar spray @ 0.1 % (T 11 ) recorded maximum cladophyll height (57.95 cm), plant spread (East to West and North to South) (74.66 cm and 52.14 cm respectively), number of cladophylls (46.86), number of primary branches (49.92), number of cladodes primary branch -1 (39.57), number of cladodes cladophyll -1 (1182.06),fresh weight of cladophylls plant -1 (156.40 g), dry weight of cladophylls plant -1 (18.90 g), number of tubers plant 1 (69.41),fresh weight of roots and tubers plant -1 (270.71g), dry weight of roots and tubers plant -1 (56.10 g) and dry matter production (104.7 g) followed by Nano NPK 4:4:4 soil drenches @ 4500 ppm + nano urea foliar spray @ 0.05 % (T 8 ).The least values were recorded with control (T 12 ).
