Effect of nitrogen doses and row direction on LAI, light transmission, plant height and dry matter production of wheat cultivars grown in pure and mixed stands

Abstract

A field experiment was conducted to study the effects of N doses and row-direction on LAI, light transmission, plant height and dry matter production in the pure and mixed stands of 3 wheat (Triticum aestivum L.) cultivars Moti, Sonalika, and NP 824 differing in plant height. The mixed stands gave more transmitted light and shorter plants than the pure stands but dry matter production was not much affected. Nitrogen application increased the plant height, LAI, and dry matter but decreased the transmitted light. Row direction had no influence on plant height, LAI and dry matter production.
