Abstract: An experiment was conducted to find out the effect of planting geometry and number of plants hill‾1 on the yield and quality of groundnut seeds. The experiment consisted of two planting geometry, viz., square planting (22.4 x 22.4 cm2) and rectangular planting (30.0 x 16.7 cm2) and three levels of number of plants hill‾1 viz., one, two and three plants hill‾1. Results showed that planting geometry affected the yield and yield components significantly. Rectangular planting gave significantly higher yield than did square planting system. But square-planting system gave significantly higher percentage of both protein and oil in seed. Two plants hill‾1 gave significantly higher yield than that of one plant and three plants hill‾1. Protein content was significantly affected due to the number of plants hill‾1 where two plants hill‾1 gave the maximum result (25.58%) which was insignificantly followed by that of three plants hill‾1 while oil content remained unaffected. The crops planted in rectangular system (30 x 16.7cm2) with two plants hill‾1 showed maximum pod yield (2.49 t ha‾1). Both protein (26.05%) and oil (50.06%) content was found higher with the crops of square planting system with two plants hill‾1. Therefore, the crops planted in rectangular system (30 x 16.7 cm2) with two plants hill‾1 emerged out as the promising practice for the improvement of yield in groundnut.
