Abstract

The incorporation of undecomposed wheat straw in the soil together with the microorganisms for its decomposition increased the yield of a groundnut crop. An increase of 37% in yield was recorded when wheat straw was inoculated with Penicillium digitatum and C:P ratio was adjusted to 65. Inoculated treatments of a narrower C:P ratio gave a higher yield than wider C:P ratio treatments inoculated with the same cultures. N uptake by groundnut plants increased due to incorporation of straw + the microorganisms. The organic C and N content of the soil increased with all treatments except the control. The highest increase in soil organic C and N was with a treatment of wheat straw of 65 C:P ratio inoculated with Staphylotrichum coccosporum. The yield of wheat after the groundnut was significantly more with several treatments than in the control plots. The highest increase of 79% in grain yield of wheat was in the plots which had previously received wheat straw of 200 C:P ratio.
