Studies on effect of manganese nutrition on quality parameters of sesame (Sesamum indicum L)
Deepika and Goswami G
A field study entitled “Studies on effect of manganese nutrition on quality parameters of sesame.” was carried out during late Rabi, 2021 at Narkhoda Research Farm, ICAR-IIOR. The soil was sandy loam in texture, slightly alkaline in reaction, low in available manganese. The experiment was carried out in two Factor randomised block design with 4 treatments and 3 replications. The treatments were viz., Control (Recommended dose of NPK) (T1), Manganese@ 2.5 kg/ha + Recommended dose of NPK (T2), Manganese @3.5 kg/ha + Recommended dose of NPK (T3), Manganese@ 5.0 kg/ha + Recommended dose of NPK (T4). This experiment was conducted in Mn deficient soil. Soil application of manganese in the form of MnSO4 was done at the time sowing. Soil application of manganese had significantly influenced the quality parameters of sesame. Oil content varied among different genotypes in different treatments. Maximum oil content (48.5) percentage was recorded in the genotype swetha at a level of application of Mn @ 3.5kg ha-1. Fatty acid content (Palmitic acid, Stearic acid and Oleic acid) values differed among the sesame varieties with different manganese treatments. The results revealed that maximum values for fatty acid contents were recorded in JCS-2454 at a level of application of Mn @ 3.5kg ha-1.
