Effect of Intercropping Summer Sunflower (Helianthus annuus L.) with Legumes on Yield Attributes and Productivity of Crops

Intercropping of Sunflower with Groundnut and Blackgram in different cropping patterns showing effects on yield attributes in sole crops and intercrops. In view of this a experiment was conducted during summer season (February to June) of 2018 at Bagusala Farm (23^o39’ N latitude, 87^o42’ E longitude) of M.S. Swaminathan School of Agriculture, Centurion University of Technology and Management, Paralakhemundi. Effect of intercropping summer sunflower with legumes on yield attributes and productivity. 9 treatments of sole, 1:1, 2:1, 3:1 ratios of sunflower¹ crop with groundnut² and blackgram³ were tested in RCBD design with three replications. The experiment revealed that superior performance in expression of yield attributes like significantly increased the yield attributes like Number of pods/capitulum per plant, Number of seeds per pods/capitulum, Number of seeds per plant, Seed weight per plant (g), 1000 seeds weight (g), Seed yield (kg/ha), Biological yield (kg/ha). It may be concluded that to obtain higher productivity of crops which are having higher productivity during summer season in sandy loam soils.
