Effect of Rice Straw Management on Growth Attributes of Potato (Solanum tuberosum L.)

Abstract

India is the second- largest producer of rice in the world, with 43.86 million hectares of land under rice cultivation where the crop residue generated is more than 160 million tons per year. The rice straw management is a challenging task in rice-producing regions. So, there is a need for an effective waste disposal technology for converting this waste into some valuable form. Keeping this in view,the present investigation was undertaken during the winter (Rabi) season of 2021-22 and 2022-23 at the Research Farm of the KVK Jagdishpur, Sonipat, Department of Vegetable Science, CCS Haryana Agricultural University, Hisar, Haryana to evaluate the effect of rice straw management on the growth attributes of potato.The seed material of potatocv. “KufriKhyati” was grown with twelve different rice straw treatment combinations. The experimental results revealed that the treatment T1 (Removing of straw + Planting) which was at par with treatment T9 (Urea (50kg/ha) + WD (25lt/ha) + FYM (1ton/ha) + Mixing of chopped straw + Planting) performed superiorly over the other treatments with significantly higher values for growth attributes viz., plant emergence (%), plant height (cm), number of stems per hill and number of leaves per hill.
