Online published on 18 April, 2020. Abstract A field experiment consisted of five planting systems namely; square, single hedge row, double hedge row, paired and cluster planting accommodated 277, 463, 617, 370 and 483 plants ha−1, respectively were laid out in randomized block design with four replications on guava cv. Sardar. The recommended doses of 480g N, 160g P2O5 and 320g K2O with 50 kg FYM per plant were applied and uniform schedule was followed in all the treatments during course of investigation. Results revealed that among the different planting systems, double hedge row planting system significantly influenced growth and yield characteristics of guava tree without adverse effect on fruit grade (weight) and quality (TSS). This system registered higher canopy volume (12.55m3), LAI (2.83), leaf: shoot ratio (240 leaves noted for the development of 9 fruits on tagged shoots) and minimum light intercept below the canopy (240 μ mol m−2 s−1) facilitating proper utilization the available solar radiation for optimum productivity under suitable planting density (617 plant ha−1). Taking productivity and economics into considerations double hedge row system of planting recorded maximum yield (15.08 t ha−1) and B: C ratio (1.96).
