摘要: Water imbalance condition (WIC) in a maize-soybean relay intercropping system is the main abiotic stress limiting biomass production and seed yield and, consequently, seed-quality. This experiment was started to study effects of WIC on soybean, which two soybean genotypes ND12 C103 were grown pots with roots split equally between soil column six treatments (%) T1 (100), T2, (100:50), T3 (100:20), T4 (50:50), T5 (50:20), T6 (20:20) field capacity both sides used. Results showed that responded significantly for all parameters; however, level response differed genotypes. Maximum osmoprotectants (except proline), biomass, yield-related traits superior quality observed ND12. Among treatments, T2 produced 94% 85%, 93% 81% yield, respectively. Similarly, also improved oil by maintaining content unsaturated fatty acids isoflavone content, while opposite trends protein content. Overall, moderate water reduction (T2 T3) can improve seed-quality selecting drought-resistant we increase under systems.
