EFFECT OF FOLIAR FUNGICIDES ON FOLIAR DISEASES AND POD, HAULM AND PLANT CRUDE PROTEIN YIELDS OF GROUNDNUT

The efficacy of three rates each of tridemorphcarbendazim‐maneb and tridemorph‐maneb and one rate each of carbendazim and tridemorph fungicide formulations on groundnut foliar disease control was studied. The application of 1.06 kg a.i./ha of tridemorph‐carbendazim‐maneb resulted in the most effective disease control and the highest pod yield of 2258–3368 kg/ha. Though spraying carbendazim formulation resulted in the highest haulm yield (4835–5581 kg/ha), plot receiving the former had the highest plant protein content of 16.3% and overall crude protein production of 831 kg/ha. Comparatively, the un‐sprayed plots were severely affected by the diseases and had significantly lower yields of 1275 kg to 1886 kg and 1790 kg to 2543 kg/ha of pod and haulm respectively; with 11.8% protein content and 218 kg/ha crude protein production. © 1990 Taylor and Francis Ltd.
