dc.description.abstractThe present investigation was carried out at PAU, Regional Fruit Research Station, Bahadurgarh (Patiala) during 2016-17 to study the effect of different chemicals and their time of application on plant growth, yield, fruit quality and days to fruit harvest. The treatments were NAA (400, 500 and 600 ppm), ethrel (1500, 2000 and 2500 ppm), urea 10%, manual bud removal and control applied on 30th April and 15th May. The maximum flower drop in rainy season was recorded with ethrel 2500 ppm followed by NAA 600 ppm and minimum in control. The mean per cent fruit set varied from 0.00 to 84.38 per cent in MBR and control, respectively. The foliar application of urea was less effective as compared to NAA and ethrel for fruit thinning in rainy season crop. First time of spray was found more effective as compared to second spray. Maximum numbers of days to fruit harvest were taken in control followed by urea, whereas the fruit harvesting was advanced by 42 days in MBR. In winter season, the mean fruit yield varied from 13.86 to 42.98 kg/plant in control and MBR, respectively. Among various chemical treatments, maximum fruit yield in winter season crop was recorded in NAA 600 ppm which was at par with ethrel 2500 ppm while minimum value was recorded in plants treated with urea 10 per cent. All the chemical treatments variably regulated the rainy season crop.en_US
