Influence of Single and Twin Row Pattern on Yieldand Yield Components of Two Groundnut (Arachishypogaea L.) Varieties in Ghana

Two field experiments were conducted in the research field of Mampong - Ashanti campus, Ghana from May to August, 2017 and 2018 to compare interactions of single or twin row pattern onyield and yield components ofgroundnut.The experimental design was a 2 x 4 factorial laid in a randomized complete block design (RCBD) with three replicates. The factors studied included: (A) Varieties [ (i) Yenyawosoand (ii) Otuhia] and (B) Row pattern [(i) 50 ? 10 cm single row, (ii) 60 ? 10 cm single row, (iii) [50 ? 20 cm] ? 20 cm twin row and (iv) [60 ? 20 cm] ? 20 cm twin row.The result showed that Otuhia produced the widest canopy spread at 86 days after planting (DAP), highest number of pods per plot, significantly higher pod weight per plot,heavier haulm weight at harvest than Yenyawoso, highest pod and seed yield (kg/ha) per plot.The 60 x20 x 20 cm twin row pattern produced the widest canopy spread at 86 DAP and highest seed yield (kg/ha) per plot in both 2017 and 2018 growing seasons.The 60 x 10 single row pattern produced the heaviest haulm weight at harvest and highest number of filled pods per plot during the 2018 growing season. Farmers should grow Otuhia variety of groundnut using 60 x 20 x 20 cm twin row pattern or 60 x 10 cm single row pattern for highest seed yield, heaviestpod and seed weight, highest number of filled pods and heaviest haulm weight as fodder to feed livestock.
