Abstract/ Executive Summary:

Bio-meal sample contains 18%P₂O₅, 11$ Ca, 0.033% Nitrogen, 0.029% K, 3293 ppm Fe, 43 ppm Mn, 94 ppm Zn & 29 ppm Cu. In acid soil like tea, the availability of added phosphorous is drastically reduced due to fixation of it by iron and aluminium. The higher percentage of calcium in the Bone-meal may help in raising the pH of the soil, thus reducing the solubility of Fe and Al and hence reduce the fixation of P. Moreover Bone- meal is a slowly decomposed material and its P and Ca is likely to be released to the soil at a slow rate and expected to be up taken by the tea plants more effectively and lowering the acidity of tea soils. Bone-meal fertilizer may be used as a liming material to raise the pH and also as a source of P. This fertilizer may impart beneficial on the yield of tea.Regular weekly data were recorded.

Commodity: Bio fertilizer

Objectives:

To know the effect of Bio-meal (bone-meal) on the yield of tea and its soil properties

Methodology:

Treatments: 4, Replication: 3, Design: RBD, Total No. Plots: 12, Treatment combination: T₁ = control T₂ = 20kg/ha Bio-meal + usual fertilizer dose, T₃ = 40 kg/ha Bio-meal + usual fertilizer dose, T₄ = 60 kg/ha Bio-meal + usual fertilizer dose Regular weekly data were recorded

Achievement/Findings:

From the experiment it is clear that Bio-meal may be recommended as organic matter for improving the tea soil health as well as the production of mature tea. The highest yield of Bio-meal (60kg/ha) with the BTRI recommended doses gave the highest yield (2282.67 kg/ha) of made which was 10.75% of higher than the control as well as it improves the pH and the content of nutrient elements such as organic carbon, total nitrogen, available phosphorous, potassium, calcium and magnesium and the rate of increase of these nutrient elements over control was 9.56%, 2.50%, 77.63%, 19.76%, 61.64%, & 56.28% respectively.
