Abstract/ Executive Summary:

A field experiment was conducted at Lungla tea estate to ascertain the fertilizer need for a medium pruned area. Thirteen treatments were replicated thrice in a randomized block design. Both pre and post treatments were used, the bushes were pruned at 55 cm and tipping was done at 35 cm height from the pruned mark. It was observed that 20 Kg N, 40 Kg P₂O₅ and 60 Kg K₂0/ha as pre treatment and 60 kg K₂0/ha as post treatment gave the highest yield increase over other treatments used in the trial.

Program Area: Crop-Soil-Water Management

Commodity: Tea

Objectives:

To study the different combinations of fertilizer and their effects on the growth and yield of a medium pruned area.

Methodology:

An area due for medium pruning was selected at Lungla tea estate conduct the experiment. Soil samples were collected from the plot and analyzed to assess the nutrient status of the soil. (Usual fertilizer application was made in the first week of May and plucking continued). Before the fertilizer application dolomite @ 500 Kg/ha was applied by broadcasting followed by a light forking in order mix the dolomite with the soil. The experiment was laid out in a randomized block design and the fertilizer application was made as per treatments. The plucking was stopped in the month of October and first split of fertilizer application was made. The plants were pruned at height of 35 cm in the month of November. Such pruning was done in two stages. Initially foliage was lopped and used as mulching material. Finally the plants were pruned at the desired height. Plants were irrigated during the dry period at an interval of 15 days. In the month of June the second application of fertilizer as per treatment was made when the plants were covered with new foliage. Tipping was done at 35 cm above the cut and plucking table was maintained. The plucking record was maintained during the season.
