dc.description.abstractA field experiment was conducted at Research farm of Department of Tea Husbandry and Technology CSK HPKV, Palampur (H.P.) during March, 2021- November 2021 to evaluate the effect of organic nutrient inputs in Tea [Camellia sinensis (L.) O. Kuntze]. The experiment comprised of 10 treatments with control (T1), FYM @ 20t/ ha (T2), vermicompost @ 10t/ha (T3), Split doses of vermicompost @ 5t/ha + 5 t/ha (T5), FYM @ 20t/ha + Jeevamrit @ 10% (T6), Vermicompost @ 10t/ha + Jeevamrit @ 10% (T7), FYM @ 20t/ha + vermiwash @ 10% (T8), Vermicompost 10t/ha + vermiwash @ 10% (T9) and Jeevamrit @ 10% (T10). The experiment was laid out in Randomised Block Design (RBD) with three replications. The soil of experiment field was silty clay loam in texture, acidic in nature, low in Nitrogen, medium in Phosphorus and Potassium. Results revealed that the growth, yield attributes and yield of tea increased with application of vermicompost @ 10t/ha + Jeevamrit @10%. Significantly higher gross return, net return and additional net return over control were recorded in treatment having vermicompost @ 10t/ha + Jeevamrit @10%. Irrespective of different treatments, the quality of black made tea was also influenced by seasonal effect. Theaflavins, thearubigin, total colour and brightness were higher in pre monsoon season followed by post monsoon and lower value was recorded in monsoon season. Among all the treatments, significantly higher theaflavins, thearubigin, total colour and brightness were recorded in vermicompost @ 10t/ha + vermiwash @10% compared to control. Application of vermicompost @10t/ha + Jeevamrit @10% recorded significantly higher available nutrients N, microbial count and microbial biomass and application of vermicompost @ 5t/ha+ vermicompost @5 t/ha recorded significantly higher P and K in soil at end of experiment in comparison to the control at the depth of 0 - 22.5 cm.en_US
