摘要：

The nitrogen availability index determined as nitric acid potential gave significant correlations with the yield of bajra, wheat and rice crops in experiments conducted on alluvial soils of Delhi at the IARI Farm. The coefficient of correlation was also the highest when data from similar experiments on wheat on alluvial, grey brown, sierozem and medium black soils from different places in India were pooled. It was found that the nitric acid potential seems to be independent of soil type and is also applicable to various agroclimatic conditions. © 1978 Martinus Nijhoff.
