INFLUENCE OF ORGANIC, INORGANIC AND BIO-FERTILIZER SOURCES ON DIFFERENT SPACING FOR VEGETATIVE GROWTH AND FRUIT YIELD OF GUAVA (CV. LALIT)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
The Field investigations were carried out know the effect of organic, inorganic and bio-fertilizers on growth and yield of guava (Psidium guajava L.) cv. Lalit" was carried out at Regional Horticulture Research Station, College of Horticulture, Bengaluru, India. The vegetative growth and yield was significantly influenced at different spacing levels (2×2, 3×3, 6×3 and 6×6 m2). In rainy season the maximum plant height (2.81 m), plant spread (N-S direction) (2.85 m), plant spread (E-W direction) (2.69 m) and canopy volume (11.76 m3) were found in 6×6 m2 spacing. Whereas, the maximum leaf area (58.13 m2) and total chlorophyll content (2.19 mg 100 g-1 FW) were found in 2×2 m2 spacing. Integrated nutrient management significantly influenced vegetative growth characteristics after 8th month of growth stage the maximum plant height (2.81 m), plant spread (N-S direction) (2.74 m), plant spread (E-W direction) (2.67 m) and canopy volume (11.71 m3) in 6×6 m2 spacing and the (2×2 m2) spacing records, the maximum leaf area (59.12 m2) and total chlorophyll content (2.53 mg 100 g-1 FW) were maximum in (T10) Azotobacter @ 20 g+PSB @ 20 g+vermicompost @ 10 kg+50% recommended NPK. The yield was significant among the different spacing of rainy season. The 6×6 m2 spacing records the maximum number of fruits (171.74), fruit yield (12.63 kg tree-1). Integrated nutrient management of (T10) Azotobacter @ 20 g+PSB @ 20 g+vermicompost @ 10 kg+50% recommended NPK wangle the maximum number of fruits (236.06), fruit yield (15.71 kg tree-1).
