Combined effects of sowing techniques and intercropping on productivity of groundnut (Arachis hypogaea L.)

Rupture of A field experiment was conducted on sandy loam soil of Kodukkanpalayam village, Cuddalore, Tamilnadu under irrigated condition during 2016-2017 to study the effects of planting techniques and intercropping in groundnut. The experiments were laid out in split plot design replicated thrice with two main and five sub treatments viz., M1 – flat bed method of sowing, M2 – ridges and furrow method of sowing, S1 – sole groundnut, S2 – groundnut + black gram, S3 – groundnut + green gram, S4 – groundnut + sesame and S5 – groundnut + cowpea. The study revealed that when groundnut seeds were sown in ridges and furrows recorded the maximum growth, yield and yield parameters. In sub plots (intercrops), groundnut intercropped with blackgram, recorded the highest growth, yield and yield parameters. Hence, this study clearly revealed that yield maximization in groundnut could be achieved by adopting ridges and furrows, intercropped with blackgram proved to be effective, economically feasible and eco-friendly approach for better returns in groundnut rather than traditional methods of sowing.
