A field experiment was carried out at Palampur during 1994-99 on 150-year-old China hybrid tea [Camellia sinensis (L.) 0. Kuntze] to study the effect of single superphosphate on yield and quality of tea with different methods, times and levels of P application. Phosphorus application at 90 kg P20,/ha with alternate years of ap- plication registered significantly highest yield. On the contrary, the highest values for tea quality with regards to total colour and percent brightness were obtained with annual application of fertilizer @ 60 kg P20,/ha with deep placement method. Among the interactions, the highest yield was obtained when phosphorus was applied in al- ternate years by broadcasting on the soil surface.References

Phosphorus is one of the major yield-limiting nutrient in in factorial randomized block design with 3 replications. most of the Indian soils (Bajaj and Ramamurthy, 1969) in Treatments comprising 4 levels of P (0, 30, 60, 90 kg general and acidic soil in particular because of its higher P,O,iha), 2 methods of P application [surface application fixation and very low recovery of applied phosphorus. (M,) and placement at 10 cm depth in a ring (M,)] and 3 The soils of Kangra district particularly in the vicinity of times of P application [once in a pruning (Y,), in alternate Dhauladhar ranges are characterized as acidic soils in years (Y,) and every year (Y,)] were started. The P ap- which nutrient availability especially of phosphorus is a plied through single suprphosphate. Basal dose of 90 kg
