Effects of Lime, Cow Manure Application with RhizobiumInoculation on Yield and Quality of the Peanut in the Grey Degraded Soil of Tri Ton town

Abstract

The field study was carried out in the grey degraded soil of Tri Ton town during Winter-Spring and Summer-Autumn crop of 2019- 2020. The field experiment was carried out by four treatments and four replications. Four treatments of Winter-Spring crop: The control treatment applied NPK (100 kgUrea + 556 kgP2O5 + 100kg KCl); (NT2): application of NPK, lime with Rhizobium inoculation; (NT3): NPK, cow manure and Rhizobium inoculation; (NT4):NPK, cow manure and lime with Rhizobium. Four treatments of Summer-Autumn cropwere carried on the prior experiment (Winter-Spring crop).However, treatments did not apply to cow manure, lime and Rhizobium(only NPK).The maximum plant biomass (168 g), number of nodule (92.1), fresh and dry weight of fill pods (61.4 and 37.6 g, respectively), fresh and dry weight of empty pods (2.07 and 1.19 g ), weight of dry nodules (0.83 g ) per plant, yield (6.12 ton ha-1), protein and oil in seeds (26.1 and 50.1%, respectively) were observed in cow manure and lime applied with Rhizobium inoculated treatments. All the parameters of growth and yield showed best result for application of lime and cow manure with synthetic Rhizobium inoculation of seeds. Cow manure has significantlyincreased the yield of peanut in the next crops. The results from our two crops of study showed that co-application of NPK, cow manure, lime and Rhizobium inoculation always increased field capacity in both crops.
