Abstract:

Maintaining yield potential and quality criteria of groundnut (Arachis hypogaea L.) are very important for late planted. This study was conducted to evaluate the protein and oil concentrations and productivity of different cultivars of groundnut grown in main and double cropping systems in the southern Turkey. Results indicated that cropping system significantly affected on characters examined. The highest pod yield was obtained when groundnut cultivars were planted as main crop in April. Across the two years study, the highest pod yield was obtained from cultivar NC 9 with 2589.4 kg ha^-1, about 781 kg ha^-1 more yielded than the plant introduction PI 269084. Oil and protein concentration and yield were affected from cropping systems. Results from the seed analyses indicated that oil concentration was higher in main cropping than in the double cropping, while protein concentration was lower in main cropping. Oil and protein yields appeared to change with cropping systems and in general, the main cropping increased oil and protein yield as a result of higher pod yield. The results of current study are consistent with the earlier reports that late planting dates negatively affect groundnut pod yield through reductions in all yield components except for protein concentration.
