Influence of different doses and methods of boron application on number of branches and yield per plot of potato (Solanum tuberosum L.) cv. Kufri Surya in varied altitudes of Andhra Pradesh

Abstract

The present investigation was carried out at three different locations of Andhra Pradesh during rabi, 2016 and 2017 to study the effect of different doses and methods of boron application on growth, yield and quality of potato (Solanum tuberosum L.). Plants were treated with different doses and three different methods of boron application viz., soil application @ 10, 15, 20 kg ha-1, tuber dipping in 0.2, 0.4 and 0.6 % borax solutions, foliar application of borax concentrations 100, 200 and 300 ppm were freshly prepared and were sprayed at 30 DAP and control treatment. The results revealed that maximum number of branches at 30 DAP, 60 DAP, before harvesting (80 DAP) and yield per plot were recorded with soil application of borax @ 20 kg ha-1 (T4) during both the years of experimentation (2016-17 and 2017-18) and in pooled analysis.
