ABSTRACT
A field study was undertaken to extrapolate the impact of foliar application of potash on physical and chemical parameters of sweet orange cv. Jaffa at experimental orchard, Department ofHorticulture, CCS Haryana Agricultural University, Hisar. The results revealed that foliar application of K2SO4 (2% and 3%) and Multi-K (3%) was found significantly or marginally better than other potash treatments in increasing physical parameters of sweet orange cv. Jaffa. Average fruit weight and fruit diameter were found to be significantly influenced by foliar application of K2SO4 (2% and 3%). Peel thickness and peel content was recorded maximum with foliar application of Multi-K (3%) which was found at par with K2SO4 (2% and 3%) treatment. Maximum juice (%) was recorded with KH2PO4 tretments which was at par with K2SO4 (2% and 3%) whereas minimum juice content was observed with KNO3 (3%) foliar application. Chemical parameters were also significantly influenced with foliar K applications. Effect of K2SO4 and Multi-K was found somewhat more pronounced than other K treatments. Maximum T.S.S, acidity, ascorbic acid values were recorded with K2SO4 (3%) and Multi-K (2% and 3%) whereas minimum values were observed in control. Leaf nitrogen content was not significantly influenced by various K sprays whereas highest leaf P content was found with KH2PO4 at 3% and leaf K content was recorded maximum with K2SO4 (2% and 3%) and KNO3 3%. The findings signify the importance of K sprays in enhancing physical and chemical parameters of sweet orange under semi-arid north-western conditions of India.
Key words: Potash, Rates of spray, Quality parameters, Leaf nutrient content, Sweet orange.
