16. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module VI Sorghum Plant Nutrient Deficiency Symptoms Your answer is not correct. Salinity, Fertility of soil, and moisture deficiencies are related to soil problems. The correct answer is: Nematode infestation could be a likely cause for irregular patterns not related to soil in a sorghum field.

17. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module VI Sorghum Plant Nutrient Deficiency Symptoms Your are right. Soil salinity could be a likely cause for poor growth with no distinct leaf pattern in a sorghum field.

18. Virtual Academy for the Semi Arid Tropics Course on Sorghum Production Practices Module VI Sorghum Plant Nutrient Deficiency Symptoms Your answer is not correct. Nutrient deficiency or toxicity do produce distinct leaf patterns. A sorghum variety by it self will not show poor growth unless affected by adverse environmental or soil factors. The correct answer is: Soil salinity could be a likely cause for poor growth with no distinct leaf pattern in a sorghum field.
