Abstract:
A field experiment entitled was conducted during kharif season of 2017 at Crop Research Farm of Tirhut College of Agriculture, Dholito see the effect of different levels of potassium on soil properties, nutrient content and uptake bykharif maize crop. Experiment was laid out in Randomized block design with four replications and nine treatments at different level of potassium (0, 30, 60, 90, 120 and 150 kg ha^-1) in which three treatments T₇, T₈ and T₉ along with 5 tons of FYM.The soil of the experimental field was sandy loam in texture, calcareous in nature with pH 8.2 and low in organic carbon (0.44%). The soil contained 210, 16.32 and 122 kg ha^-1 available N, P₂O₅ and K₂O, respectively. N and P content of grain and stover were non-significant due to different treatments. However, significantly higher K content of grain and stover was recorded with treatment T₉ (T₄ + 5 t FYM ha^-1). Significantly higher N, P & K uptake of grain and stover were recorded under T₉ (T₄ + 5 t FYM ha^-1) as compared to other treatments.
