Summary

Effect of interaction between level of nitrogen and phosphorus on The performance of root crop of radish

The yield per ha and dry matter content in leaves at harvest were improved by the application of nitrogen as compared with control. The application of 50 kg N/ha was found to be the best dose. The length of root, Number of leaves per plant, length of largest leaf and width of largest leaf were increased by the application of nitrogen. The various doses of nitrogen were similar in imparting their effect jn these respects. Therefore, the application of 50 kg nitrogen per hectare was proved as the best dose.The parameters, i.e. diameter of root, fresh weight of root and dry weight of tops were not affected significantly due to the application of nitrogen. The yield q/ha, diameter of root and fresh weight of tops were improved by the application of phosphorus when compared with control. The application of 30 kg phosphorus/ha was found to be best dose. The maximum fresh weight of root (85.50 g/plant) was obtained by the application of the highest doses of phosphorus (90 kg/ha). This treatment was better than other doses in respect of length of root, fresh weight of roots dry matter content in root (%), number of leaves, length of largest leaf and width of largest leaf. The maximum length of root 15.43 cm was recorded with the supply of 150 kg nitrogen and 90 kg phosphorus per hectare (N3P3). The minimum length of root 8.18 cm was obtained under control. On the basis of finding of the present study it may be concluded that under the agro-climatic conditions resembling to that of Agra, the maximum yield of radish may be obtained by supplying 50 kg nitrogen and 30 kg phosphorus per hectare.
