EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON GROWTH AND YIELD OF TOMATO CV. PUSA EARLY DWARF

In order to determine the response of tomato cv.Pusa Early Dwarf to organic and inorganic sources of plant nutrients and their combinations, the present investigation was carried out at the Agriculture Farm, Doon (PG) College of Agriculture Sciences & Technology, Selaqui, Dehradun (Uttarakhand).The layout of experimental field was completely randomized block design with three replications.The field experiment included treatments viz., sole applications of recommended dose of fertilizers (RDF), farm yard manure (FYM) and Vermicompost (full doses); and combined applications of organic and inorganic sources of plant nutrients (half doses) along with control (without manures and fertilizers), forming seven different treatments, which were distributed randomly in each block.The experimental findings indicated that treatment T 6 (50% RDF + 50% vermicompost) gave maximum plant height (37.44, 62.75 and 71.55 cm, respectively), number of branches (5.93, 8.00 and 12.33, respectively) and number of compound leaves (28.42, 40.18 and 49.50, respectively) at 30 and 60 days after transplanting, and at harvesting; number of fruits per plant, fruit length, fruit breadth, average fruit weight, yield per plant, yield per plot and yield per hectare (25.16, 5.90 cm, 4.20 cm, 61.83 g, 1.56 kg, 46.73 kg and 39.33 t, respectively).
