Abstract
A field experiment entitled “Effect or nano urea fertilization on growth yield
and quality of Nagauri methi (Trigonella corniculata L.)” was carried out during Rabi
season of 2022-23 at the College of Agriculture, Jodhpur. The experiment consisted
12 treatments viz., control, 2 ml/l nano urea, 4 ml/l nano urea, 50% RDN, 50% RDN
+ 2 ml/l nano urea, 50% RDN + 4 ml/l nano urea, 75% RDN, 75% RDN + 2 ml/l
nano urea, 75% RDN+ 4 ml/l nano urea, 100% RDN,100% RDN + 2 ml/l nano urea
and 100% RDN + 4 ml/l nano urea, and was laid out in Randomized Block Design
(RBD) with three replications.
The results of the study clearly indicate that application of 100% RDN + 4
ml/l nano urea recorded the highest plant height, number of branches per plant,
internodal length, total number of cuttings and minimum number of days taken for
first cutting and shortest average cutting interval over the control. The treatment 75%
RDN + 4 ml/l nano urea remained at par with 100% RDN + 4 ml/l nano urea. Quality
parameter of Nagauri methi like iron content of leaves, chlorophyll content, protein
contents of leaves and seed were significantly higher with application of 100% RDN
+ 4 ml/l nano urea over the control and statistically at par with 75% RDN + 4 ml/l
nano urea. The lowest values of these parameters were recorded with control
treatment. The maximum fresh and dry herb yields and seed yield were recorded
markedly higher with application of 100% RDN + 4 ml/l nano urea, being statistically
at par with 75% RDN + 4 ml/l nano urea. The lowest values of these parameters were
recorded with control treatment. Significantly higher net returns (₹ 322565/ha) and
B:C ratio (3.05) were obtained with application of 75% RDN + 4 ml/l nano urea over
the control followed by 100% RDN + 4 ml/l nano urea net returns (₹ 322540/ha)
and B:C ratio (3.04). Hence, 75% RDN + 4 ml/l nano urea application can
be beneficial for producing higher productivity and net returns of Nagauri methi in
western Rajasthan.
