Description |
The present investigation was undertaken to study the effect of different sources of fertilizers with stage wise rates of application on growth, yield and quality of tomato (Solanum lycopersicum var. Arka Vikas) during Rabi, 2013-14 at Vegetable Research Station, Rajendranagar, Hyderabad. The experiment was laid out in Randomized block design comprising of seven treatments with three replications. The treatments consist of two sources viz., water soluble fertilizers (Ammonium Sulphate and Soluble fertilizer [13-0-45 NPK]) and straight fertilizers (Urea and Murate of Potash). Each treatment was divided into three splits and given as stage wise from 045 days, 46-90 days and 91-135 days of crop duration where Phosphorus applied as basal dose in the form of SSP in all the treatments, and the fertigation was given at five days interval. Conventional application of urea, single super phosphate and murate of potash following drip irrigation were taken as control. From the study, the results enunciated that the growth parameters were influenced by different sources of fertilizers in split doses applied at stage wise significantly. Highest leaf area (913.73 cm2) at 90 days after transplanting (DAT), dry matter production per plant at 45 DAT (69.37g), 90 DAT (75.90g) and 135 DAT (77.43g) respectively, days to first fruit set (43.0) and days to first fruit harvest (62.7) were recorded with fertigation of straight fertilizers at the rate of 33 per cent each at 45,90 and 135 DAT and found to be on par with water soluble fertilizers fertigated at the rate of 33 per cent each at 0-45,46-90 and 91-135 days stages while, plant height and number of primary branches were found to be non-significant. Data on yield and yield contributing characters differed significantly among the different treatments. Number of fruits per plant (39.86), average fruit weight of tomato (51.80 g), fruit yield per plant (2005 g), marketable fruit yield per plant (1966 g) and fruit yield per hectare (668.63 q) and crop duration (144.0 days) were registered significantly higher with application of 100 per cent recommended dose of straight fertilizers at the rate of 33 per cent, each upto 0-45,46-90 and 91-135 days stages of the crop and were on par with fertigation of water soluble fertilizers at the rate of 33 per cent each at 0-45,46-90 and 91-135 days stages. With regard to the quality parameters there was no significant difference among the treatments except for lycopene and ascorbic acid content of the fruit. However higher values for lycopene (7.42 mg/100g) and Ascorbic acid (3.27 mg/100g) were recorded with application of 100 per cent recommended dose of straight fertilizers at the rate of 33 per cent each given at 0-45, 46-90 and 91-135 days stages and were on par with water soluble fertilizers at the rate of 33 per cent each at 0-45, 46-90 and 91-135 days stages. The highest cost: benefit ratio (1: 3.32) was obtained with the fertigation of straight fertilizers at the rate of 33 per cent of recommended dose each at 0-45, 46-90 and 91-135 days stages. The lowest cost: benefit ratio (1: 1.18) was recorded in control. |
