Abstract

In two field trials conducted at Aligarh (India), K content was studied in two varieties each of radish and turnip, grown under three regimes of nitrogen (100, 150 and 200 kg ha 1). The number of leaves and dry matter content of tops and roots of both crops increased with increasing doses of N. With the increase of N fertilizer, radish biomass production, economic output and the root yield increased with the increase of economic output per kg of nitrogen from the negative to a positive correlation, and the growth yield is also growing. Appropriate amount of nitrogen fertilizer increased the plant's largest leaf length, maximum number of photosynthetic leaves, tops and root dry matter accumulation in various organs in radish and turnip varieties, showed a positive correlation between nitrogen deficiencies reduced dry matter accumulation amount. K content also increased with increasing doses of N, with 200 kg ha 1 giving the highest value. Local variety of each crop possessed comparatively less K content. Maximum K content was noted in Pusa Rashmi (radish) and Snow Ball (turnip) grown with 200 kg ha 1. At early stage, K content was more in tops, but as the plants grew the content became higher in roots.
