Effect of Meteorological Parameters under Different Shade Tress Influencing the Yield of Tea (Camellia sinensis L. Kuntze)

A field experiment was conducted at C.R.Farm, Gayeshpur, Nadia, West Bengal to study the effect of different climatic factors under different shade trees influencing the yield of tea. The results showed the productivity of tea under shade tree Acacia auriculiformis was highest (8231.88 kgha⁻¹) followed by shades under Casuarina (8172.13 kgha⁻¹), Gmelina (7751.34 kgha⁻¹ Eucalyptus (7630.66 kgha⁻¹) and Sissoo (7329.68 kgha⁻¹). Highest biomass yield of tea was obtained from the pruning's of Gliricidia (927.59 t ha⁻¹) followed by Sissoo (23.60 t ha⁻¹), Albizia (16.06 t ha⁻¹) and Acacia (11.97 t ha⁻¹). PAR received from the different plants followed the following sequences Gmelina> Casuarina> Eucalyptus>Acacia> Sissoo. In view of all the important parameters of tea production like total green yield of tea, tree biomass yield and total PAR received, Acacia, Casuarina, Gmelina and Eucalyptus were considered as ideal shade trees under new alluvial zone of West Bengal.
