    Effect of crop residues and FYM on yield and quality of carrot roots (Daucus carota L.)
    (CCSHAU, 2005) Ashwini Kumar; Rana, M.K.
    The present study entitled “Effect of crop residues and FYM on yield and quality of carrot roots (Daucus carota L.)” was carried out at Vegetable Research Farm of CCS Haryana Agricultural University, Hisar during winter season of 2004-05. The experiment comprising twelve treatments, viz. T1 (maize root incorporation), T2 (sorghum root incorporation), T3 (pearl millet root incorporation), T4 (dhaincha root incorporation), T5 (maize root incorporation + recommended decomposed FYM), T6 (sorghum root incorporation + recommended decomposed FYM), T7 (pearl millet root incorporation + recommended decomposed FYM), T8 (dhaincha whole plant incorporation), T9 (recommended decomposed FYM), T10 (recommended un-decomposed FYM), T11 (recommended NPK), T12 (control) was laid out in a randomized block design with three replications and 3x3 m plot size. Ten competitive plants were randomly selected from each experimental treatment to record data on various parameters, which were influenced significantly by various treatments. The crop residues had negative effect on all the characters studied during the course of experimentation. Incorporation of recommended decomposed farmyard manure in soil increased the root length, shoot length, average crown diameter, dry matter content, TSS content, and carotene content, however, decreased the forking of carrot roots significantly. Similarly, application of recommended dose of NPK had significant positive effect on all the characters mentioned above in addition to cortex: core ratio, root: shoot ratio and yield. The study suggested that for getting maximum root yield of carrot the crop should be supplied with recommended dose of NPK, and so far quality was concerned farmyard manure and recommended NPK had similar effects, however, incorporation of crop residues produced adverse effect on growth, yield, and quality attributes.
