Abstract
An experiment was under taken on “Effect of recycling of cotton stalks on yield and yield attributes of cotton under dry farming condition”on medium black clayey soil at Dry Farming Research Station, Junagadh Agricultural University, Targhadia (Rajkot) during Kharif 2017-19. The experiment was laid out in strip plot design with three replications. The experiment consist of five main plot treatments viz.; S1- Removal of cotton stalks from plot, S2- Surface burning of cotton stalks, S3- Incorporation of cotton stalks using rotavator, S4- Incorporation cotton stalks using mobile chopper and S5- Ex-situ composting of cotton stalks using shredderand three sub plot treatments viz.; D1- One irrigation for decomposting, D2- One irrigation + addition of N @10 kg/ha through urea + compost culture @ 5 kg/ha, D3 - Addition of N@ 10 kg/ha through urea + compost culture @ 5 kg/ha at sowing,thus, fifteen treatment combinations. The stalks management practice S5 (Ex-situ composting of cotton stalks using shredder) recorded maximum seed cotton yield (1875 kg/ha). Whereas, effect of de-composting practices on yield attributes and seed cotton yield was found non-significant. However, the maximum seed cotton yield (1823 kg/ha) was recorded under de-composting practice D1 (one irrigation for decomposting).
