Abstract

                                Field application of BHC to redgram (Cajanus ca/an L.) at rates higher than the recommended level of 1 ppm a. i. resulted in adverse toxicity towards germination and growth. Dry matter and grain yields were reduced drastically with progressive Increase in BHC levels. However, BHC had no deleterious effect on nodulation or nitrogen uptake by the surviving redgram plants. Application of composted farmyard manure (FYM) at 0.2, 0.4 and 0.8% carbon levels in soil overcame the toxic effects of 6,10 and 25 times, respectively of the recommended BHC rate.
