Economic evaluation of finger millet under different crop geometries and nutrient management practices

Abstract

Field experiment with finger millet was conducted at Agricultural college farm, Bapatla during the kharif seasons of 2018 and 2019. The experimental design was split plot with three replications. The trial comprised of three crop geometries with different age of seedlings (30x10 cm with 30 days old seedlings, 30x30 cm with 15 days old seedlings and 45x45 cm with 15 days old seedlings) in main plots and seven nutrient management practices (S0: absolute control, S1: FYM @ 10 tonnes ha-1 + application of dravajeevamrutham, S2: FYM @ 10 tonnes ha-1 + application of dravajeevamrutham along with wooden log treatment, S3: FYM @ 10 tonnes ha-1 + 100% RDF, S4: FYM @ 10 tonnes ha-1 + 100% RDF along with wooden log treatment, S5: FYM @ 10 tonnes ha-1 + 125% RDF, S6: FYM @ 10 tonnes ha-1 + 125% RDF along with wooden log treatment) in subplots. The highest grain and straw yields, gross and net returns and return per rupee investment were observed with closer spacing of 30x10 cm, transplanted with 30 days old seedlings. Among the nutrient management practices tried application of FYM @ 10 tonnes ha-1 + 125% RDF along with wooden log treatment had superiority in grain and straw yields, gross and net returns and return per rupee investment compared to other nutrient management practices.
