dc.description.abstractA field experiment was conducted during kharif 2019 at Agronomic Main Research Station, Odisha University of Agriculture & Technology to find out nutrient management in finger millet through organic sources. The experiment was laid out in a complete randomized complete block design replicated thrice with ten treatments viz. T1 - 8t/ha FYM, T2 - 4t/ha FYM, T3 -T2 + 125 l/ha waste decomposer, T4 - T2 + 15kg/ha sea weed extract, T5 -T2 + 15 kg/ha wild ark with sea weed extract, T6 -T3 + 15 kg/ha sea weed extract, T7 - T3 + 15 kg/ha wild ark with sea weed extract, T8 - T6 + 4 kg/ha Growth G, T9 - T7 + 4 kg/ha Growth G and T10 - control. The soil of the experimental plot was sandy loam with pH 5.34, EC 0.045dsm-1, organic carbon 0.42%, available nitrogen 238.2 kg/ha, available phosphorus 17.2kg/ha and available potassium 147.8 kg/ha. Finger millet variety “Arjuna” was the test crop. The study revealed that application of 8t/ha FYM produced maximum finger millet grain yield of 2821 kg/ha. This higher production was associated with better growth and development of the crop particularly in terms of more number of earheads hill-1(5.2), more number of fingers earhead-1(6.4), higher spikelets per finger(68.3),more grains spikelet-1(5.7)and higher test weight(3.36g). At this level of production and nutrient source(8t/ha FYM), finger millet removed about 61.1 kg nitrogen, 13.9 kg phosphorus and 63.6 kg potassium/ha. Soil available N improved by 21.9 kg/ha, available P by 4.7 kg/ha and available K depleted by 0.6 kg/ha due to 8t/ha FYM. This also recorded maximum net return of Rs.36, 309/ha and higher benefit-cost ratio of 1.80. However, the effect of 8t/ha FYM was at par with 4t/ha FYM + 125 l/ha waste decomposer + 15kg/ha wild ark with sea weed extract + 4kg/ha Growth G with respect to grain yield, nutrient removal , soil fertility change, net return and benefit cost ratio.en_US
