    Question: November sown berseem crop induce the weed

    Options:

    Chenopodium sp
    Anagallis spp
    Vicia spp
    all of these

    ✅ EXPLANATION: November sown berseem crop can induce Chenopodium sp, Anagllis spp, and Vicia spp weeds. This is because berseem is a winter legume crop that is sown in November and harvested in March-April. Mild winter temperatures and sufficient moisture during this period create favorable conditions for the germination and growth of these weeds.
    • A. Chenopodium sp: These are fast-growing weeds that can compete with berseen for resources like light and water. They are also known to host plant diseases that can harm berseen crops.
    • B. Anagllis spp: These are small, flowering weeds that can reduce the quality of berseen hay. They can also harbor pests that can damage crops.
    • C. Vicia spp: These are vetch weeds that can twine around berseen plants, reducing their growth and yield. They can also fix nitrogen in the soil, which can further promote the growth of other weeds.
