Abstract
Browntop millet (Brachiaria ramosa L.) is an important small millet, rich in
micronutrients and fiber content. It is hardy crop growing in moisture and nutrient limiting
condition. It is rich in nutrients, much work not done on planting density and nutrient
application is not yet fully standardized in seed production. In the view of above facts study
on Standardization of seed production techniques in browntop millet was undertaken at
NSP, UAS, GKVK, Bengaluru during rabi 2018 to popularize its importance. Twelve
treatment combination were arranged in factorial randomised block design with three
replications, which includes three spacing levels (S1 - 22.5 x 10 cm) , (S2 - 30 x 10 cm) and
(S3 – 45 x 10 cm) four nutrient levels (N1 - 20:20:0, N2 - 20:20:10, N3 - 30:20:10 and N4 -
40:20:10 NPK kg ha-1
). The results revealed that treatment combination (S3N4) with wider
spacing and higher dose of nitrogen level recorded maximum growth, seed yield and
quality attributes viz., plant height (113.26 cm), total number of tillers plant-1
(13.36), total
number of productive tillers plant-1
(12.03), panicle weight plant-1
(28.5 g), seed yield
plant-1
( 26.5g), test weight (3.98 g), seed germination (92.53 %), seedling vigour index –
I (1714) and SVI- II – (1139), EC (268.17 µS cm-1
),seed protein content (11.25 % ) and
over narrow spacing treatments with less nitrogen application (S1N1) registered (80.15
cm, 8.36, 7.03, 22.28 g, 21.5 g, 3.07 g, 83.6 %, 1435, 868, 372.30 µS cm-1
, and 10.65 %
respectively) less values.
