Growth and Yield of Tea (Camellia sinensis) as Influenced by Nano Urea during Pre and Post Pruning Opertation
Year: 2023
Type: article
Abstract: The growth and yield parameters of tea on mature plants of TV 23 clone were studied after application of Nano-urea as foliar spray at Experimental Garden for Plantation Crops, Assam Agricultural University, Jorhat during the period 2021-22. Bud breaking number and time attain to tipping height were two growth parameters observed after pruning operation was carried out. Numbers of bud break was counted 30 days, 40 days and 50 days after pruning respectively. After 50 days maximum bud breaking number (106/ plant) was observed in 0.5% Nano-urea applied plot. To attain that height, lesser time was required (51 days) by the same plot. Plucking density, fine leaf count and green leaf yield were three yield parameters observed during first, second and rain flush. Plucking point density was found maximum (50 no/m2) during rain flush where 0.4% Nano-urea applied in 3 sprays. Fine leaf count was found maximum during first flush than it decreasing during second flush and rain flush respectively. The green leaf yield was found high in the plot where 0.4% Nano-urea applied in 3 sprays during rain flush.
