Summary Over the past years, the tea industry in India has started to suffer from various drawbacks, i.e. issues regarding low productivity and rising input costs (namely the uneconomic age profile of tea bushes across the tea estates of North Bengal), leading to a decline in the industry and dramatic expansion of small tea growers. Accordingly, the vast expansion of small tea plantations in North Bengal prompted this study to examine the purpose and outcome of such an expansion concept. In the present study, Bhotepatty, Maynaguri (the Jalpaiguri district), was considered due to an immense conversion of agricultural land into numerous small tea plantations in the region. The study focuses on the agricultural shift from potato fields to small tea gardens. Initially, a cumulative approach encompassing the preliminary survey work and analysis of soil physicochemical characteristics was adopted to assess the adequacy of this agricultural shift. The survey conducted revealed the lack of proper land preparation, land rehabilitation before planting, sound soil nutrient management, and soil testing programs after shifting (responsible for the depletion of major nutrients such as potassium and phosphorus in the tea soil, which can be resolved with proper and timely manuring practices). Sulphur and the organic matter, organic carbon and available nitrogen of the top soil were detected in huge amounts compared to the optimum values suggested by the Tea Board of India.

Valorization of agro-industrial waste resources is today’s main topic for the agribiotechnology researchers. This research work was designed to valorise tea industrial waste, i.e., manufactured by-products from CTC (crush-tear-curl) tea factory. Physicochemical analysis has been carried out to characterize tea waste treated soil. Pot experiment was considered to study impact of tea waste on plant growth. Morphological parameters such as length of plants and pods, and girth diameter were considered for growth study. Effect of tea factory waste on soil nutrition was found remarkable with increased organic carbon, organic matter, nitrogen, phosphorus, potassium, and sulphur content. Pot culture revealed impact of tea waste composted soil on boosted plant growth. GC-MS based metabolite profiling revealed xanthosine and caffeine as major compounds in tea waste extract. A possible pathway has been proposed to explain the role of xanthosine and caffeine breakdown in fertilization of soil and plant growth. Disposal of tea wastes produced during tea manufacturing can be managed in a sustainable manner if this research is implemented industrially. This research portrays a notable nutrient richness in tea waste treated soil. Detection of purine metabolites revealed remarkable fertilizing and plant growth promoting properties of CTC tea waste.
