 ABSTRACT

The present investigation was carried out at Fruit Research Farm, Horticulture Unit, B.H.U., Varanasi (U.P.) during the year 2012-2013. The experiment was conducted with foliar feeding of different levels of Zinc and Boron and their combinations on guava cultivar L-49. The main objective of the research was to study the effect of boron and zinc on the quality of guava fruits and to work out the economics of different treatments. The average fruit weight (239.18 g), fruit volume (230.77 ml), specific gravity (1.03), polar diameter (7.30 cm), radial diameter (7.12 cm) of fruit at harvest were recorded maximum with foliar spray of Borax 0.4% + Zinc Sulphate 0.8%. Minimum acidity (0.20 %) was recorded in treatment T8 (Borax 0.4% + Zinc Sulphate 0.8%). The quality parameters like total TSS (12.65 °Brix), TSS/acid ratio (63.25), ascorbic acid content (210.86 mg/ 100 g pulp) was maximum with foliar spray of Borax 0.4% + Zinc Sulphate 0.8%. The cost benefit ratio was found maximum (1:8.43) in T8 (Borax 0.4% + Zinc Sulphate 0.8%). From the study it can be concluded that various quality parameters were improved with the foliar application of Borax 0.4% + ZnSO4 0.8% and it was economically viable treatment.

Key words: Psidium guajava, Zinc, Boron, Economics, Quality
