Abstract
A field experiment entitled „„Effect of Organic Manures and
Mulching on Growth, Yield and Quality of Radish (Raphanus sativus L.)”
was conducted during Rabi season 2021-22 at Horticulture Farm,
S.K.N. College of Agriculture, Jobner, Jaipur (Rajasthan). The
experiment comprised of sixteen treatment combinations including four
treatments of organic manures (Control, FYM @ 9 t/ha, vermicompost
@ 3 t/ha and poultry manure @ 3.6 t/ha) and four treatments of
mulching (Control, saw dust @ 10 t/ha, plastic mulch and wheat straw
@ 5 t/ha) were taken in Factorial Randomized Block Design with three
replications.
The results of the study clearly indicated that application of O2
(Vermicompost @ 3 t/ha) significantly increased the plant height
(17.28 and 31.19 cm), number of leaves per plant (6.41 and 12.46) at
30 and 45 DAS respectively, leaf area (272.00 cm2
), chlorophyll
content (1.76 mg/g) in leaves, root diameter (6.13 cm), length of root
(25.03 cm), shoot weight (48.00 g), root weight (128.48 g), shoot : root
ratio (2.63), root yield (9.52 kg/plot and 264.54 q/ha), ascorbic acid
content (12.95 mg/100g), net returns (Rs 282606/ha) and B:C ratio

(2.47) except treatment O3 (Poultry manure @ 3.6 t/ha), which
was statistically at par with O2 in terms of net returns.
Similarly, application of M2 (Plastic mulch) significantly increased
the plant height (17.66 and 31.66 cm), number of leaves per plant (6.42
and 12.43) at 30 and 45 DAS respectively, leaf area (270.44 cm2
),
chlorophyll content (1.78 mg/g) in leaves, root diameter (6.21 cm),
length of root (24.89 cm), shoot weight (48.34 g), root weight (128.51
g), shoot : root ratio (2.65), root yield (9.69 kg/plot and 269.31q/ha),
ascorbic acid content (12.60 mg/100g). However, application of M3
(Wheat straw @ 5 t/ha) gives higher net returns (Rs 280068/ha) and
B:C ratio (2.62) except treatment M2 (Plastic mulch), which was
statistically at par with M3 in terms of net returns.
Further, the combined application of O2M3 (Vermicompost @ 3
t/ha with Wheat straw @ 5 t/ha) were proved to be significantly superior
in terms of net returns (Rs 333640/ha) and B:C ratio (3.06). Thus, on
the basis of net returns and B:C ratio combined application of O2M3
(Vermicompost @ 3 t/ha with Wheat straw @ 5 t/ha) is worth
recommended to fetch maximum net returns per hectare from radish.
