Direct and residual impact of boron fertilization improves the crop yield, nutrient contents, nutrient uptake, and nutrient use efficiencies in cauliflower–cowpea–okra sequence in an acidic Inceptisol of North East India

Aim: To investigate the impact of biochar as component of integrated nutrient management on nutrient uptake by tomato in acid soil of Meghalaya, North East India. Methodology: A field experiment was conducted at research farm of SNRM, College of Post Graduate Studies in Agricultural Sciences (CPGS-AS), Central Agricultural University (CAU-I), Umiam during rabi 2017-18 taking tomato, cv. Megha Tomato-2 as test crop. Sixteen treatment combinations of recommended closes of fertilizers, biochar and vermicompost? were tested in RBD with three replications.? Results: The experimental results revealed that combined application of biochar, fertilizers and vermicompost increased the uptake and availableof N, P, K, Fe, Zn, Mn and Cu over graded doses of biochar + fertilizers, biochar alone and control. Electrical conductivity, bulk density, exchangeable acidity, exchangeable aluminium and acid saturation followed the same trend.? Interpretation: The 100% RDF + biochar 4 t ha-1 + vermicompost @ 2.5 t ha-1 is the most appropriate combination for increasing tomato productivity and improving soil health of acidic soil in Meghalaya.

Plot Design

An experiment was conducted at CCS Haryana Agricultural University, Hisar during rabi 2010-11 and 2011-12, consisting of three irrigation frequencies viz. one irrigation at CRI, two irrigations at CRI and heading and four irrigations at CRI, late tillering, heading and milking in main plots and five nitrogen levels (0, 50, 100, 150 and 200 kg N/ha) in sub-plots in strip plot design with four replications. Grain yield and NUE increased significantly with increased irrigation levels. Increase irrigation frequency increased the N (33.4 and 31.3 %), P (42.2 and 42.3 %) and K (26.7 and 25.1 %) uptake over one irrigation during 2010-11 and N (16.0 and 15.9 %), P (19.4 and 20.7 %) and K (11.2 and 13.5 %) during 2011-12. Increased nitrogen dose increased the protein content, hectolitre weight, sedimentation value and grain yield over control. Maximum and minimum nutrient uptake was recorded with 200 and 0 kg N/ha.
