Pusa-362) under agri-horti system and growth of guava tree. The experiment was laid in Factorial Randomised Block Design with ten treatments (30 kg P2O5 ha-1 alone, 45 kg P2O5 ha-1 alone, 60 kg P2O5 ha-1 alone, 30 kg P2O5 ha-1 with Rhizobium, 45 kg P2O5 ha-1 with Rhizobium, 60 kg P2O5 ha-1 with Rhizobium, 30 kg P2O5 ha-1 with Rhizobium and PSB,45 kg P2O5 ha-1 with Rhizobium and PSB, 60 kg P2O5 ha-1 with Rhizobium and PSB, the control (no phosphorus and biofertilizers). In chickpea, the highest growth parameters and yield attributes of chickpea were recorded with progressive increase in phosphorus level up to 60 kg P2O5 ha-1 with dual inoculation of seeds with Rhizobium and PSB proved to be profitable boosting grain yield (1568 kg ha-1) and gave the maximum net return (Rs. 65460 ha-1). Under agri-horti system, guava + chickpea (application of 60 kg P2O5 ha-1 with dual inoculation of seeds of chickpea with Rhizobium and PSB) gave highest net returns (Rs.153070 ha-1) and B-C ratio (2:69) as compared to other treatments integrated with guava fruit tree. The highest tree height, canopy diameter, stem girth and fruit size of guava was recorded in association with chickpea.EnglishThesis
