A field experiment was conducted on sandy loam soil to study the effect of applied zinc and boron to the residual blackgram in maize-blackgram cropping system during (2011-12) kharif season. There were three and nine levels of NPK as main treatments and Zn and B as sub plot treatments respectively. Results revealed that soil application of ZnSO4 and Borax @ 50 kg and 10 kg ha-1 (S8) respectively combined with recommended 100% NPK ha-1 to the proceeding crop, significantly recorded the highest dry pod (690.3 kg ha-1) and haulm yield (803.2 kg ha-1) with increase being 52.16 and 50.7% over control for the successive residual blackgram. The same treatment also greatly influenced the yield attributes viz., the highest number of pods plant-1 and 100 seed weight and found on par with treatment (S9).
