摘要：Mineral nutrition is undoubtedly one of the foremost environmental factors to which plants respond. The present study aimed to investigate the effect of various combinations of phosphorus (organic and inorganic sources) on the yield and mineral profile of two tomato cultivars i.e. Falcon and Rio Grande for two consecutive years (2009 and 2010). These cultivars were assessed under six different organic and inorganic fertilizer treatment combinations viz. 0-0, 100-0, 75-25, 50-50, 25-75 and 0100% of poultry manure (PM) and Triple Super Phosphate (TSP), respectively. All the factors (P source, cultivar and year) alone and in combination significantly (P<0.05) affected the yield and mineral profile of tomato fruit. Yield of both cultivars increased with increase in PM up to 50% and thereafter decreased with further increase in PM percentage. Highest yield (59.50 t ha-1) was recorded for Falcon in 50-50 treatment during 2010, while lowest yield was recorded for Rio Grande in control treatment in the year 2009. Mineral content (P, Fe, Zn and Cu) of the tomato fruit generally increased with increasing percentage of PM up to 75% in Rio Grande during 2010. Further increase of PM percentage decreased mineral content of the fruits. Highest concentration of Boron was recorded in Rio Grande under treatment of 50% PM and TSP each. Results of this study show that application of organic P-source can effectively reduce use of inorganic fertilizer along with increase in yield and mineral content in tomato.
