Abstract

Aim: To examine the effect of foliar spray of micro - nutrients on fruit growth and yield of guava (Psidium guajava L.) cv. Lalit.

Study Design: The Randomized Block Design (RBD) experimental design was used.

Place and Duration of Study: An experiment was carried out during Hasth Bahar flowering seasons of 2021-22 and 2022-23 at Horticulture Research Farm of Babasaheb Bhimrao Ambedkar University.

Methodology: There were nineteen treatments with three replication. The variety selected for experiment was Lalit.

Results: The foliar application of Borax 0.2%+Zinc 0.4% was found to be the best treatment in improving the morphological characteristics of guava such as fruit length (8.59 cm), fruit width (8.6cm), fruit volume (169.09 cm), fruit weight (174.99 g), peel weight (17.13g), pulp weight (155.32g),number of seed per fruit (212.49),seed weight per fruit (2.53g), seed weight kg per plant  (1.23 kg), pulp and seed ratio (61.29) and specific gravity (1.03 g cc-1) of guava fruit.

Conclusion: On the basis of the result obtained in the present investigation, it is concluded the combined foliar application of Borax 0.2%+Zinc 0.4% (T11). Therefore, combined spray Borax 0.2%+Zinc 0.4% (T11) can be advocated to guava growers for maximum growth and yield parameters of guava.

Keywords: Lalit, foliar application, morphological characters, micro-nutrient, Guava
