Online Published on 20 December, 2022. Abstract A field experiment was conducted at the model farm of Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during the years 2016-17 and 2017-18 to see the effect of foliar application of nitrogen and potassium on leaf nutrient content of fig. Thirteen treatment combinations were arranged in a randomized block design comprising two levels of nitrogen viz N0.5 (0.5% urea) and N1.0 (1.0% urea); two levels of K viz K1 (1.0% KNO3) and K2 (2.0% KNO3) and two application times viz September and January. Experiment was replicated thrice. The maximum leaf N was recorded under treatment comprising N1.0 + K2.0 (2 sprays at 15 days interval in September) (2.71%), N1.0 + K1.0 (1 spray in September and 1 in January) (2.55%) and N1.0 + K2.0 (1 spray in September and 1 in January) (2.52%). In 2017, treatment N1.0 + K2.0 (1 spray in September and 1 in January) resulted in maximum (0.34%) phosphorus content. The same treatment resulted in maximum Ca content of 5.36 per cent in 2018 and 4.64 per cent under pooled data and Cu content of 9.4 ppm in 2017.
