Effect of foliar spray of zinc and iron on floral characters expression and yield attributing parameters of guava cv. L-49 in vertisols of Subhumid plains of South Eastern Rajasthan

Abstract

A field experiment was conducted at Fruit Instructional Farm of College of Horticulture and Forestry, Jhalawar during June 2019 to December 2019 to study the effect of foliar spray of zinc and iron on yield attributes of guava cv. L-49. The experiment comprising 16 different treatments of ZnSO4 and FeSO4 was laid out in Randomized Block Design with four replications. The results revealed that foliar application of zinc and iron under T15 treatment (ZnSO4@ 0.60 % + FeSO4@ 0.60%) resulted in outcome of maximum number of flowers per shoot (12.00), fruit set (77.88%), fruit retention (80.47%), fruit : leaf ratio (0.33), number of fruits per plant (215.00), fruit length (7.69 cm), fruit diameter (7.89 cm), fruit weight (260.60 g), fruit volume (230.25 cc), estimated yield per plant (55.91 kg), estimated yield qt./ha. (155.42 qt.) as compared with rest of the treatments.
