IMPROVING GOAT PRODUCTION IN THE ‘COCONUT TRIANGLE’ OF SRI LANKAM.M.Mahusoon, P.Sivarajahhttp://www.digital.lib.esn.ac.lk//handle/123456789/38442019-06-21T07:10:38ZIMPROVING GOAT PRODUCTION IN THE ‘COCONUT TRIANGLE’ OF SRI LANKA
M.M.Mahusoon, P.Sivarajah
A field survey was conducted in the districts of Kurunegala and Puttalam in the Coconut
Triangle , to study the goat production systems in the area, and the problems faced. A random
sample of 150 goat farmers, from 5 villages in the two districts, were interviewed using a
structured questionnaire. Goat farms of three different herd sizes small herd (<5 goats), medium
herd (5-10 goats) and large herd (>10 goats) exist in the area. These farms differed in resource
characteristics. Women are more involved in rearing of goats. Contract leasing of goats reared
was observed among small herd farmers. Large herd farmers provided special housing to goats.
Small herd farmers do supplementary feeding of goats. Controlled herded feeding on grasses and
shrubs is common or goats roam freely. Goats are sold on the basis of their live-weight. A lack of
extension services for goat production exists in both the districts. Goat farmers had poor
knowledge on improved nutrition, better disease control and breeding superior breeds. Some
policy implications for developing goat production are discussed.
EFFECT OF DIFFERENT LEVELS AND FREQUENCY OF NITROGEN APPLICATION ON THE NODULATION OF GROUNDNUT (Arachis hypogea L) IN REGOSOLST.Thanaraj, S.Sandanamhttp://www.digital.lib.esn.ac.lk//handle/123456789/38432019-06-21T07:08:59ZEFFECT OF DIFFERENT LEVELS AND FREQUENCY OF NITROGEN APPLICATION ON THE NODULATION OF GROUNDNUT (Arachis hypogea L) IN REGOSOLS
T.Thanaraj, S.Sandanam
This investigation was conducted in order to study the effect of levels and frequency of nitrogen
application on the nodulation of groundnut in the regosols. The experiment tested five levels of
nitrogen (0, 15, 30, 45 and60 kg/ha). A uniform application of 15 kg N/ha, 45 kg K O/ha and 60
kg P /ha was made as basal dressing. Topdressing at the rate of 15, 30 and 45 kg N/ha was
done either as a single application or in two split doses. There was a significant increase in
nodulation at lower level of nitrogen i.e. upto 30 kg/ha thus emphasizing that a minimal amount
of applied nitrogen is necessary for nodulation. There was also an indication of reduction in
nodulation at the highest level of nitrogen tested.
SCOPE OF ENHANCING NODULATION OF GROUNDNUT THROUGH SOIL AMENDMENTS BY CROP RESIDUES OF WIDE C:N RATIOSThedchanamoorthy.

Thedchanamoorthy. K, Gurung
A pot experiment was conducted to study the effect of different crop residues having wider C:N
ratios, on nitrogenase activity, nodulation and biomass of inoculated groundnut. The experiment
indicated a positive effect on nitrogenase activity, nodulation and biomass of inoculated
groundnut through soil amendments by crop residues of wide C:N ratios.
