Potential yield of groundnut (Arachis hypogaea) based intercropping system as influenced by different irrigation regimes
Syed Abul Hassan Hussainy and Vaidyanathan R
A field trial was conducted during kharif season of 2017 and 2018 to study the Potential yield of groundnut (Arachis hypogaea) based intercropping system as influenced by different irrigation regimes. Groundnut intercropped with blackgram resulted higher in number of branches/plant (7.18) with increased crop growth rate and relative crop growth rate during the stages of growth. Irrigation scheduling of IW/CPE ratio 0.75 significantly improved the growth of groundnut crop with higher number of branches/plant (7.08), increased CGR and RGR throughout the crop growth. Number of pods/plant of 12.7 were recorded under groundnut blackgram combination with haulm yield of 4010 kg/ha and was followed by sole crop of groundnut. Lower yield gap of 35.7% was observed in groundnut + pearlmillet combination. IW/CPE ratio 0.75 resulted least in yield gap by 34.1% in comparison to the other Irrigation scheduling. From the study, groundnut + blackgram intercropping system with irrigation scheduling at 0.75 IW/CPE ratio enhances the growth and yield of the system.
