Abstract
Cereal + legume intercropping provides greater scope for minimizing the adverse impact of moisture and nutrient stress, improves system productivity, and soil health. The lack of adherence to row proportion geometry during crop sowing in the region results in a notable decline in crop productivity. Therefore, this study, conducted in the summer of 2022 at the experimental farm of the College of Post-graduate Studies in Agricultural Science, Umiam, Ri-Bhoi, Meghalaya, aimed to evaluate the intercropping indices and yield attributes for assessing the biological and competitive effectiveness of baby corn and green gram under various planting patterns. The experiment was laid out in randomized block design (RBD) with eight treatments and replicated thrice. The results indicated that planting patterns led to significantly higher yield attributes, grain yield, and stover yield in both sole cropping systems. Additionally, there was no significant difference when compared to the 3:3 strip planting systems used in the study. Among the different spatial arrangements, 3:3 strip planting of baby corn + green gram had been found to be more remunerative and efficient in terms of competition indices and biological efficiency than the rest of the treatments.
