this combination in different industrial frameworks
Effective sex reversal of nile tilapia (oreochromis niloticus) using oral administration of 17-αmethyltestosterone in different concentrations
Get PDFIn Tilapia farming, early reproduction and slow growth of females pose
significant challenges. Various methods exist for achieving this, aiming to
address the aforementioned constraints in Tilapia farming by ensuring a
predominance of faster-growing male fish. The research aimed to enhance
sex reversal efficiency in Tilapia by elevating hormone concentration and
altering feeding duration. Three-day-old Tilapia fry was fed 17-αmethyltestosterone mixed feed at 90mg/kg and 120mg/kg concentrations for
20 and 30 days. Four treatments were implemented, each with three
replicates. Sex reversal percentages and growth parameters were assessed
and compared using ANOVA with Minitab Version 18.0, providing insights
into optimizing hormonal sex reversal techniques for Tilapia farming. The
experiment of 120mg/kg feed fed for 30 days produced significantly higher
males (94.99±1.67%, p<0.05, ANOVA) and showed significantly lower
growth rates (28.42±0.18g weight and 9.67±0.01 cm total length at 90 days
of age) than other treatments. Therefore, by considering the growth
parameters (32.37±0.01g weight, 11.90±0.03cm total length at 90 days of
age) and sex reversal efficiencies (93.33±0.01%,) the experiment of
120mg/kg feed fed 20 days was selected as the best concentration for sex
reversal in Tilapia. Although this experiment did not achieve complete sex
reversal, it improved the sex reversal percentages compared to past studies.
Also, feeding only for 20 days with 120mg/kg reduces the environmental
impacts of hormone accumulation in the environment compared to 30 days
of feeding which is currently in use
Evaluation of root and shoot morphology of four rice crosses of f₃ generation in upper catena soil conditions
Get PDFRice is the most important agricultural crop and staple food in Sri Lanka.
With the growing population and changing climatic conditions, it is
necessary to grow with increased yield potential. The objectives of this
research were to identify F₃ crosses exhibiting superior root and shoot
morphology, suitable for enhancing performance, and select superior plants
for F₄ generation evaluation in breeding programs aimed at root
improvement in upper catena conditions. A total of 150 progeny lines,
comprising four rice crosses, relevant parents and standard tests were tested
in a randomized complete block design with two replications. Data were
analyzed using IBM SPSS statistical software. In the tested four crosses were
recorded higher phenotypic coefficient of variance and genotypic coefficient
of variance values for the number of tillers, number of effective tillers, root
volume, root length, root width, number of roots, root dry weight, number of
panicles, total panicle weight and seeds per panicle. (Cross 3) Ld 20-11-3/
Ld 21-6-18-2 cross showed better mean performance for plant height, culm
height, flag leaf length, flag leaf width, root volume, root length, panicle
length, no of panicles, total panicle weight, seeds per panicle. (Cross 4) Ld
20-15-14/ Ld 20-22-4 cross showed better mean performance for, no of
tillers, no of effective tillers, root width, no of roots, and root dry weight.
Among the four rice crosses, crosses 3 and 4 showed better growth, yield
performance and root performance, therefore crosses 3 and 4 have the
potential to develop rice lines with better root structure in future rice breeding
programs

No full textBetel (Piper betle L.) is a popular intercrop with
coconuts in Kurunegala and Gampaha districts,
mainly grown as a cash crop. To ensure selection
of high quality, vigorous plants, growers often use
potted betel plants for transplanting. The
traditional potting media for betel consists of
equal parts topsoil (TS), sand (S), cow dung (CM)
and coconut flour (CD). However, due to the high
cost and limited availability of sand and coir dust,
using partially burned paddy husk as a substitute
is
a more economical option. A study was
conducted to determine the cost-effective potting
mixture using a combination of different potting
materials.
Seven treatments included the
combinations of top soil, sand, cattle manure, coir
dust, and partially burned paddy husk (PBPH).
The poly bags were filled with a plotting mixture
and three nodal cuttings were planted. A
propagator was used to raise the plants for 21
days. The small plants were then kept in 70%
shade. According to the results, the highest root
dry weights were in the T2(TS:CM:S:CD:PBPH
2:1:1:1:3) and T7 (TS:CM:PBPH, 1:1:3). The
highest shoot dry weight, shoot length, and
number of leaves were all observed in T4
(TS:CM:S:CD
2:1:1/2:1:1). Therefore, treatments T4, T2, and
T7 can be recommended for betel propagation.
The cost per plant in the T4, T2, and T7 treatments
was Rs 13.50, Rs 11.50, and Rs 9.30, respectively,
which is lower than the cost of the conventional
potting mixture at Rs 18.00
Foliar epidermal micromorphology: a contribution to the taxonomy of family Oleaceae
Get PDFOleaceae (olive family), includes 28 genera and about 700 species. Nevertheless, there remains a lot to uncover about the group’s historical development, the evolution of various reproductive and dispersal mechanisms, and polyploidization episodes appear to be linked to its diversification. In the current study, foliar epidermal anatomy of 13 plant species and 2 varieties from 7 genera of Oleaceae was examined under a light microscope. The qualitative and quantitative features like stomatal density, size,shape of guard cell, number of epidermal cell, subsidiary cells, and structure and density of trichomes were analysed using a light microscope. This was the first study on the foliar micromorphology of various Oleaceae taxa. Almost all species exhibited hypostomatic type except one in which Amphistomatic type was observed. Most of the stomata were anomocytic while some Paracytic and one diacytic stomata were also seen. Maximum stomatal length of (30.80 + 1.44 μm) and lowest of (18.30 + 0.21 μm) was noted. All trichomes observed were unicellular. Both glandular and non-glandular trichomes were observed with highest trichome length (237.75–248.00 = 242.25 + 1.73 μm) and the lowest (100.00–101.75 = 100.75 + 0.32 μm). Plant taxonomists might commence their future research with the micro-morphological aspects of foliar epidermal morphology, which exhibit a number of innovative qualities for accurate taxonomic identification

The impact of packaging materials on paddy (at362) quality preservation and shelf-life extension: an iotenabled study
Get PDFThis study investigates the efficacy of various packaging materials for paddy
preservation, integrating IoT technology for internal environmental
monitoring. NodeMCU boards were utilized to monitor internal
environmental conditions, with wires extending from the NodeMCU to the
packaging materials containing paddy. Over two months, manual
assessments of seed qualities were conducted. Initial assessments and
monthly measurements provided data for analysis. Python scripting and
SPSS software were employed for data analysis. ANOVA tests were
conducted to examine differences among the packaging materials and across
different time intervals for variable parameters. For the material factor, the
p-value exceeded 0.05, indicating a lack of significant differences among the
packaging materials. However, for the time factor, the p-value was below
0.05, signifying statistical significance. This detailed examination revealed
significant changes over time, providing a nuanced understanding of how
these variables evolve during the course of the study. The significance level
was maintained at 0.05 throughout the analyses, ensuring robust and reliable
results. These detailed findings highlight the nuanced changes in properties
with respect to packaging materials. Tin, while ensuring a stable humidity
environment, showed unexpected consequences on insect multiplication.
Polypropylene and jute bags, closely mirroring external conditions,
demonstrated distinctive effects on bulk density and other physical
properties. The study's results provide valuable insights for selecting
packaging materials for paddy preservation, offering a comprehensive
approach to understanding the dynamic changes in the internal environment
of paddy packaging
