| Abstract | ||
| In order to study the effects of manganese sulfate in increasing seed yield of four safflower genotypes (Carthamus tinctorius) under rainfed conditions, this experiment carried out in Maragheh agricultural research station. The experiment was arranged with four Mn fertilizer levels (0,10,20,30 kg ha-1) as soil application together with two foliar spray levels (1% and 2%) of 1.5 kg ha-1 manganese sulphate with four Safflower genotypes (V1=19829 V2=333،,V3=335 and V4= Sina), as factorial based on RCBD design with four replications. At maturity, plots were harvested and biomass and grain yield were measured. The results of combined (two-year) analysis showed that manganese application increased 100 kg ha-1 grain yield and 500 kg ha-1 biomass. It can be concluded that manganese sulfate fertilizer application (at a rate of 10 kg ha-1 in the soil) or foliar spray (1.5 kg ha-1) would increased crop yield in safflower under rainfed condition. | ||
