Results

  • Application of Polysulphate in addition to chicken manure resulted in an increase in yield of 21% compared to the zero treatment (T1)
  • Application of Polysulphate in addition to chicken manure resulted in an increase in protein content in grains, and 30% higher protein yield than the zero treatment (T1)
  • The 1,000 grain weight in T3 (Polysulphate + chicken manure) was slightly higher (increase of 2%) than the zero treatment (T1)
