Abstract
An experiment was conducted in Annamalainagar, Tamil Nadu, India to evaluate the effect of organic manures, i.e. farmyard manure (FYM) at 25 t/ha, FYM + pressmud (PM) at 12.5 t/ha each and PM at 25 t/ha, applied with different levels of N and P (50, 75 and 100% of the recommended NPK dose of 100:50:50 kg/ha) with or without biofertilizers (Azospirillum + phosphate solubilizing bacteria), on the growth and yield of aubergine cv. Annamalai. FYM + PM at 12.5 t/ha each along with 100% NPK + biofertilizers recorded the highest values for plant height (108.90 cm), number of primary branches (11.66) and number of leaves (94.05), whereas FYM at 25 t/ha along with 100% NPK + biofertilizers recorded the highest values for stem girth (3.71 cm), number of secondary branches (15.58) and leaf area (68.62 cm2). These treatments also recorded the lowest number of days to first flowering and days for 50% flowering as well as the most number of flowers. However, FYM at 25 t/ha along with 100% NPK + biofertilizers recorded the highest fruit set percentage (65%), number of fruits (26.64), fruit yield per plot (62.92 kg) and estimated fruit yield (31.67 t/ha).
