Abstract
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.
