摘要

An on-farm trial was conducted with a view to observe the efficiency of urea super granule on growth and yield of tomato. The variety 'Arka Vikas' was tested at farmers' field in the Haveri district of Karnataka for two consecutive years during 2005-06 and 2006-07. The trial was laid out in randomized block design with three replications. Two forms of urea i. e. prilled urea and urea super granule with different rates were used. The results revealed that urea super granule had significant positive effect on the yield of tomato as compared to normal urea. The recommended dose of N (150 kg/ha) from urea super granule gave the significantly highest fruit yield of 79.13 t/ha in 2005-06 and 73.60 t/ha in 2006-07. The yield obtained with the application of 90 and 80% recommended dose of nitrogen from urea super granule was statistically identical to the yield obtained from 100% recommended dose of N from prilled urea. The 150 and 135 kg/ha of N from urea super granule gave 11 and 2% higher yield of tomato than that of using 150 kg/ha N from prilled urea, respectively. These results implied that efficiency of urea super granule was found to be positive on the yield of tomato and 20% N could be saved using urea super granule compared to prilled urea. The economic analysis also showed that the use of urea super granule was economically viable to cultivate tomato. The farmers were found to be quite happy with the higher yield of tomato for the application of urea super granule and they expressed their willingness to use urea super granule for tomato cultivation.
