The experiment was under taken to study the effect of nitrogen and boron on growth, yield and quality of winter guava fruit. The vegetative parameters increased with increasing doses of nitrogen and maximum percent increase in plant height ( %), shoot length ( cm), tree girth ( %) and plant spread ( %) were obtained with application of nitrogen @ 800 g/plant. | Impact of nitrogen and boron on some vegetative, reproductive and quality of guava (Psidium gujava L.)
