Abstract

Cultivars and nutrient management determine productivity and quality of the organic finger millet. A field trial was carried out during the kharif season 2022 at Binjhagiri, Bhubaneswar, Odisha comprising the four cultivars of finger millet and four nutrient management practices through organic manure combinations with split plot design replicated thrice. The four cultivars namely, C1- ‘Arjuna’, C2- ‘Bhairabi’, C3- ‘Chilika’ and C4- ‘Kalua’ were assigned to the main plots. Recommended dose of nitrogen (RDN) such as 50 kg ha-1 was supplied through varying percentage of organic manures namely, farmyard manure (FYM), neem oilcake (NOC) and vermicompost (VC). Four nutrient management practices such as N1- FYM (RDN100), N2- FYM (RDN40) + NOC (RDN30) + VC (RDN30), N3- FYM (RDN50) + NOC (RDN25) + VC (RDN25), N4- FYM (RDN60) + NOC (RDN20) + VC (RDN20) were assigned to the sub-plots. Combination of the treatments viz., C3N2, C4N2, C3N3 and C4N3 excelled over the others for grain and protein yields and profitability, but treatment combination C4N2 was the most promising considering the parameters like grain yield (2.10 tha-1), net return (Rs. 36940 ha-1), protein yield (165.75 kg ha-1), calcium yield (7.34 kg ha-1) and iron yield (0.137 kg ha-1). There was significant positive correlation of grain yield with all growth-yield parameters, except test weight, whereas regression analysis indicated 70.86, 85.21 and 73.45% contribution of tillers hill-1, dry matter production and leaf area index at harvest, respectively, to variations in grain yield. The organic finger millet growers should cultivate cv. ‘Kalua’ with application of FYM+NOC+VC @ 4.35+0.34+0.6 t ha-1 for achieving maximum yield and grain quality.
