Extract

The effect of fertilizers in increasing the yield of clover seed was examined by a series of manurial trials. The initial mineral status of the crop and the extent of the uptake of the applied nutrients were determined by analyses of the leaf. The techniques for sampling and analysing leaves to determine mineral status are described.

The high yields of seed and lack of response to fertilizers in trials at Cambridge led to their being repeated at Saxmundham on land known to be extremely deficient in minerals. Even then there was a response only to phosphate which although significant was small.

Leaf samples were also collected from commercial crops of red clover in 1955, 1956 and 1957. The analyses of these samples indicted that none of them was as deficient as the crops at Saxmundham, and no relationship was found between mineral status and seed yield.

It is concluded that yields of red clover seed in Eastern England are not likely to be increased materially by the application of fertilizers.
