Response Of Fingermillet (Eleusine Coracana L.) Under Organics And Inorganics On Soil Physico-Chemical Properties In Entisols

Abstract

Soil health is an appropriate function of soil within ecosystem boundaries. Soil health is assessed in terms of soil physico-chemical properties of soil. The Field experiment was conducted during, 2022 at Valiyampattu Village, Sankarapuram Taluk, Kallakurichi District, Tamil Nadu. Soil of the experimental field was sandy loam in texture. The soil belonged to the Pachol (Phl) series, Entisol in order. The taxonomic classification of the soil was Paralithic Ustorthent. The bulk density, particle density, pore space and water holding capacity of the initial soil were 1.47 Mg m^­-3, 2.21 Mg m^­-3, 33.48 and 23.27 per cent, respectively. The experiment consists of twelve treatments which were replicated thrice. The design of the experiment was randomized block design (RBD). The twelve treatments included in the study were T₁ - Absolute Control, T₂ - 100% RDF (N;P₂O₅:K₂O) (60:30:30 kg ha^-1), T₃ - 75% RN(C.F) + 25% RN(GLMC), T₄ - 75% RN(C.F) + 25% RN (GOC), T₅ - 75% RN(C.F) +25% RN (PMC), T₆ - 75% RN(C.F) +25% RN(CPC), T₇ - 50 % RN(C.F) + 25% RN (GLMC) + 25% RN(GOC) , T₈ - 50 % RN(C.F) + 25% RN(PMC) + 25% RN(CPC), T₉ - 50 % RN(C.F) + 25% RN(GLMC) + 25% RN(PMC), T₁₀ – 50 % RN(C.F) + 25% RN(GLMC) + 25% CPC, T₁₁ - 50% RN(C.F) + 25% RN(GOC) + 25% RN(PMC) and T₁₂ - 50% RN(C.F) + 25%RN (GOC) + 25% RN(CPC). The results revealed that the combined application of 50% RN through chemical fertilizer + 25% RN through GLMC + 25% RN through GOC (T₇) recorded bulk density (1.30 Mg m^-3), Pore space (42.73%), maximum water holding capacity (30.69%), pH soil reaction was noticed of (6.45), Electrical conductivity (0.16 dSm^-1) and at post – harvest soil over control (T₁).
