Abstract/ Executive Summary:

Fertilizer is on the major agro-input contributing to the cost of production and productivity of tea plantation. The present fertilizer recommendation was introduced in the year of 1994.This recommendation is being followed till to date. But Global environment is changing silently. As a result soil character changing as a part of environment. The soil health is decorating day by day. Now it needs to upgrade the present fertilizer recommendation with the change of soil health. So a long term experiment(2012-2015) was initiated in the year 2012 to identify a new recommendation of chemical fertilizer for tea plantation with the change of soil environment on the basis of production.The result shows that in every treatments yield was increased over control. Highest yield 1644 kg/ha made tea was recorded in the treatment T₆ where N80, P25, K50 and Zn10 were applied.

Keywords: Fertilizer recommendation, yield, Zinc and tea

Location: BTRI farm and Srigobindapur Tea estate

Start Date: 01-01-2012

End Date: 31-12-2015

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To identify a new recommendation of chemical fertilizer for tea plantation with the change of soil environment on the basis of production.

Methodology:

Treatments: 7, Replication: 3, Plot size: 35.60, Design: RBD, Treatment combination: T₁ = Control, T₂ = 40 (kg/ha) N +5 (kg/ha) P₂O₅ + 30 (kg/ha) K₂O + 10 (kg/ha) Zn, T₃ = 50 (kg/ha) N +10 (kg/ha) P₂O₅ + 35 (kg/ha) K₂O + 10 (kg/ha) Zn, T₄ = 60 (kg/ha) N +15 (kg/ha) P₂O₅ + 40 (kg/ha) K₂O + 10 (kg/ha) Zn, T₅ = 70 (kg/ha) N + 20 kg/ha) P₂O₅+ 45 (kg/ha) K₂O + 10 (kg/ha) Zn, T₆ = 80 (kg/ha) N +25 (kg/ha) P₂O₅ + 50 (kg/ha) K₂O + 10 (kg/ha) Zn, T₇ = 90 (kg/ha) N +30 (kg/ha) P₂O₅ + 55 (kg/ha) K₂O + 10 (kg/ha) Zn Regular weekly data were recorded.
