    SOME CULTURAL PRACTICES IN CROP PRODUCTION

    1) Transplanting The transfer of seedlings from nursery beds to their permanent positions in the field. The tools used for transplanting are handtrowel, digger, hoe or cutlass. Plant is removed with a ball of soil around its roots. Mostly done in cool weather, in morning or evening times. Transplants require shading to reduce wilting. Soil around roots at permanent site are firmed to eliminate air pockets for good root establishment. Watering is done morning and evening. Mulch after transplanting to reduce evapo-transpiration. Usually done at the early stages of development of the crop plant, long before maturity. Weak or diseased seedling should not be transplanted.   2) Shading Art of…
