 ABSTRACT

In depth study focusing to ascertain the effect of foliar sprays of ZnSO4 (0.50, 0.75 and 1.00%), FeSO4 (0.2, 0.4 and 0.6%), K2SO4 (0.5, 1.0 and 1.5%) and Urea (1.0, 1.5 and 2.0%) along with control (water spray)before flowering and after fruit set, during rainy and winter seasons, in improving the growth, flowering, fruiting characteristics and yield of guava (Psidium guajava L.) cv. L-49 was carried out in the Experimental Orchard of Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2016-17. The findings of the experiment revealed that the foliar application of various nutrients significantly increased the growth rate, flowering and fruiting characters of the plants over control. Maximum increase in plant growth in terms of plant height (11.57%), plant spread (8.33 and 8.63% N-S and E-W direction) and stem girth (5.82%) were recorded in the plants receiving ZnSO4 @1.00 per cent, which was statistically at par with ZnSO4 @0.75 per cent and Urea @2.0 per cent. Average shoot length was also recorded maximum (28.21 cm) in plants sprayed with ZnSO4 @1.00 per cent closely followed by ZnSO4 @0.75 per cent (28.14 cm) and Urea @1.5 per cent (27.67 cm). Maximum number of flowers per branch (19.66 and 14.74), fruit set (61.17 and 70.24%) and yield per plant (32.76 and 29.31 kg/tree) were recorded with minimum number of days for fruit set from flowering (18.00 days and 21.07), fruit drop (19.52 and 14.27%) and number of days for fruit maturity (94.90 and 119.2 days) under the treatment ZnSO4 @1.00 per cent, during rainy and winter seasons, respectively. Application of ZnSO4 @0.75 per cent was also found to be equally good, during both the seasons of investigation.
