Effect of silica and potash on yield and quality of cashewnut (Anacardium occidentale L.) in lateritic soils of Konkan

A field experiment was conducted to study the ‘Effect of silica and potash on yield and quality of cashewnut (Anacardium occidentale L.) in lateritic soils of Konkan’, at Rukhi Block of All India Co-ordinated Research Project on Irrigation Water Management, Central Experimental Station, Wakawali, Dr. B. S. Konkan Krishi Vidyapeeth, Dapoli, during the year 2022-23 to 2023-24. The experiment was laid out in Factorial Randomized Block Design consisting two factors viz. three levels of potash (K0, K1 and K2) and five levels of silica with soil (S0, S1, S2) and foliar application (S3 and S4) at flowering and nut development stage, comprising fifteen treatment combinations and three replications. There were two trees were selected for each treatment. Total ninty uniform cashew trees of variety Vengurla-4 were selected from the orchard at the slope of the hill. The quality parameters includes protein and oil content (%), in which protein was significantly affected by various treatments.
