Abstract
The present investigation was carried out to study the “Effect of integrated nutrient
management on growth, yield and quality of guava (Psidium guajava L.) cv. Hisar Safeda” in the
Department of Horticulture, CCS Haryana Agricultural University, Hisar during 2022-23. The
experiment comprised of twelve different treatments with three replications and were laid out in
randomized block design (RBD) to assessed the effect of integrated nutrient management on growth,
yield and quality of guava. The results revealed that all the integrated nutrient treatments at different
doses had significantly influenced growth, yield, physical and quality parameters over absolute control.
Among different treatments, for yield parameters, T7 (100 % NPK (RDF) + ZnSO4
(0.5 %) + B (0.2 %)
+ Fe (0.5 %) as foliar spray + bio-fertilizer) performed better in terms of number of fruit/plant (256.5),
average fruit yield (42.45 kg/plant). Furthermore, physical parameters, T7 (100 % NPK (RDF) + ZnSO4
(0.5 %) + B (0.2 %) + Fe (0.5 %) as foliar spray + bio-fertilizer) was found better in terms of diameter
of fruit (7.08 cm), length of fruit (6.99 cm), average seed weight (1.95 g), fruit volume (168.6 cc).
Moreover, for quality parameters, T7 performed better in terms of TSS (12.98 oB), acidity (0.36 %),
TSS/Acid ratio (36.06) and sugar content i.e. total sugar (7.74 %), reducing sugar (4.62 %) and non reducing sugar (3.12 %), pectin content (0.97 %), and ascorbic acid content (200 mg/100 g pulp).
However, parameters i.e. specific gravity were observed non-significant means all the treatments at
different doses were not significantly influenced this traits
