Effect of inoculum size and nutrition on the host/parasite relations of Striga sene-galensis on sorghum



Effect of inoculum size and nutrition on the host/parasite relations of Striga sene-galensis on sorghum



Plant & Soil, 15: 1-12



In sand cultures of sorghum, inoculation with 1 g ground seed-pods containing 1 % (by volume) viable Striga seeds reduced growth of the host only after the parasite emerged from the soil. Heavier inoculum caused less emergence of the parasite and losses in the host plant even before emergence. Low water requirements of NPK-deficient hosts permitted the support of a greater weight of parasite without leading to increased losses.
