Authors: Maknickiene Z. , Asakaviciute R.
Published: March 2024

Breeding for disease resistance is one of the most difficult tasks in breeding work. Rapid mutation of pathogen’s populations, its ability to continuously form a large amount of races differing in virulence and aggressiveness are the chief obstacles in the development of disease-resistant lupine varieties. Of 2019—2021 year twelve narrow-leafed forage lupine genotypes developed by the individual selection methods and characterised by a high resistance to anthracnose (Colletotrichtum gloesporoides (Penz.) Penz & Sass.) resistance 7—9 points, rapid growth rate, and a high seed yield 1.3—3.8 t/ha were tested at the competitive variety testing trials. The investigated lines are a valuable material from the viewpoint of genetics, breeding and agronomic characteristics which will be used in subsequent breeding work and the most promising lines will be transferred to the official variety testing.

The main purpose of this study was to evaluate the effect of nitrogen fertilization, with different levels and type of fertilizers, on the agrochemical evolution of the soil superficial horizon and on nitrates levels in maize leaves in different growth stages (5 leaves, flowering and milk maturity). Two type of nitrogen fertilizers (Ammonium nitrate and Urea) and five nitrogen levels (80 kg/ha; 120 kg/ha; 200 kg/ha and 240 kg/ha) were applied in experimental trails. Filed experiments were conducted at the Agricultural Research and Development Station (ARDS) of Suceava, Romania, during years 2021 and 2022. The pH of the soil in the conditions of fertilization with ammonium nitrate, was acid with values between 4.88—4.65 in the first vegetation stages, and between 4.36—4.3 at the end of the vegetation period. Referring to response of maize plant to the fertilization levels and type of fertilizers showed some influences on chemical content of maize leaves in different growth stages. Concerning the presence of nitrates in maize plants, this study showed that the nitrates contents was highest in the first growth stage of maize plants, particularly when ammonium nitrate fertilizer was used.

Published: March 2024

The aim of the given paper was to estimate the effectiveness of biologically active substances with kairomone properties on the behavior of the entomophagy’s Trichogramma evanescens and Bracon hebetor in the vision of increasing the parasitism potential of different ontogenetic stages of pest development. Biologically active substances with kairomone properties were obtained and tested for increasing the biological indices of the entomophagy’s Trichogramma evanescens and Bracon hebetor. The alcohol-based extract and eggs of the laboratory host Sitotroga cerealella — as a source with kairomone properties for the entomophagy Trichogramma evanescens, and the alcohol-based extract from the larvae and excrement of the laboratory host Galleria melonella — as a source with kairomone properties for the entomophagy were used Bracon hebetor. It was found that due to the influence of kairomone substances, the female entomophagy’s Trichogramma evanescens and Bracon hebetor become more active in searching for eggs and larvae for parasitism, compared to the control variant. It has been demonstrated that biologically active substances, emitted by pest species for the purpose of communication between individuals of the same species, can also be used as kairomone substances by different species of entomophagy’s. The given factor can be further developed with the aim of application in plant protection as a means of activating and increasing the effectiveness of both released and natural entomophagy’s.

Authors: Prihambodo Dimas
Published: March 2024

Islam as ad-din and civilization are big themes in this era. This can be seen in the emergence of works that attempt to explain this, written by Indonesian scholars such as Nurcholish Madjid, Syeid Muhammad Naquib al-Attas, Kuntowijoyo, M. Amin Abdullah, and others. This article attempts to revive Islamic studies in the discipline of 'ulum al-hadith regarding the criteria for the validity of hadith sanads and research steps. The results of this writing show that sanad is an arrangement in the form of levels of narrators of a hadith. Broadly speaking, the criteria for rijalu sanad are fair and careful. Research also found that the steps for researching hadith sanads can be formulated into several steps, including takhrij hadith, i'tibar hadith, research using the sanad scheme, researching ar-Ruwat dates and researching al-jarhu wa at-ta'dil.

Published: March 2024

The oyster mushroom (Pleurotus ostreatus) was cultivated on diverse substrates, encompassing wheat straw (T1), paddy straw (T2), groundnut leaves and straw (T3), sugarcane bagasses (T4), cotton stalk (T5), coconut husk (T6), pigeon pea straw (T7), and banana pseudostem (T8). The study comprised of the estimation of proximate composition, antioxidants, and mineral content of the sun-dried mushrooms during the initial two harvests. The average values of nutritional parameters were as follows: moisture (90.93 to 85.18 %), ash (7.62 to 4.86%), carbohydrates (37.57 to 20.10%), crude protein (45.45 to 23.10%), crude fiber (29.08 to 19.29%), crude fat (2.68 to 1.63%), total phenol (14.23 to 9.12 mg/g) and ascorbic acid (11.58 to 8.72 mg/100g). The average mineral content exhibited the trend K>P>Mg>Ca>Zn>Fe>Cu. Upon consideration of average values from both harvests, the groundnut leaves and straw had the highest crude protein (45.45 %), total phenol (14.23 mg/g), ascorbic acid (11.58 mg/100g), phosphorous (0.43 %), iron (7.12 mg/100g) and zinc (12.43 mg/100g). The paddy straw resulted in the highest crude fiber (29.08 %) and crude fat (2.68 %), while the wheat straw resulted in the highest potassium (1.52 %) and calcium (179.65 mg/100g). The various substrates had an impact on nutritional parameters as seen by either an increase or decrease in various parameters which can be reflected in turn by the composition of the substrates itself. In conclusion, groundnut leaves and straw (T3) along with paddy straw (T2) and wheat straw (T1) resulted in significant improvement of nutritional composition compared to other treatments. This study underscores the environmentally friendly utilization of nutrients from agricultural waste for mushroom production.

Published: March 2024

The current study aims to inter-compare the performance efficiency of the single and the dual source surface energy balance modeling approaches, namely EEFlux and SETMI, respectively for real time catchment scale - crop water demand estimations. For this, the afore-stated two surface energy balance modelling approaches were applied on the Narmada Canal Project, Sanchore, Rajasthan, India for estimating catchment scale actual evapotranspiration (ETa) values for the Rabi cropping seasons of the years 2013-14 and 2018-19, after incorporating the basic satellite data derived inputs viz. Land use, Land surface temperature and Gridded weather data. Due to the non-availability of the catchment scale ground based daily reference evapotranspiration (ETo) values for the study area, the Global Land Data Assimilation System based gridded meteorological data product was utilized, as a substitute for obtaining observed actual evapotranspiration (ETa) values for the investigated Rabi seasons of the study area. These actual evapotranspiration values were compared with those estimated through the single source, EEFlux and the dual source, SETMI modelling approaches to ascertain their comparative performance efficiency through the use of the five statistical indices viz. Mean Absolute Error, Root Mean Square Error, Mean Bias Error, Nash-Sutcliffe Efficiency and the Index of Agreement. The investigations revealed almost at par performance of the two modelling approaches. However, it was concluded that in contrast to the more detailed dual source approach i.e., SETMI, the simple single source approach i.e., EEFlux seemed to be more promising due to its user-friendly implementation and input data automation.

Do Natural Resource Abundance Spur Economic Growth in Nigeria?
Authors: Adamu Ibrahim Mohammed , Bawa Sani , Tukur Danlami
Published: March 2024

The present paper investigates the relationship between natural resource abundance and economic growth for Nigeria covering the period 1970 to 2016. Our methodology encompasses autoregressive distributed lag (ARDL) bound test to cointegrating approach augmented by Bayer and Hanck combined cointegration test. Empirical results confirm a long run relationship among the variables under examination. More importantly, findings indicate that natural resource exerts a negative and significant impact on economic growth in both long run and short run dynamic analysis. This validates the Sachs and Warner’s hypothesis that natural resource is a curse than a blessing in Nigeria. Hence, the study stresses the needs for diversifying the non-resource based sectors to support the economy.

Published: March 2024

To date, finding the most effective method to teach SE students is extremely challenging. This study used the project-based learning approach which applies computational thinking techniques by engaging students via inquiry based, hands on and student centric in teaching the software engineering Project course to students enrolled in a software engineering program. The objective of this study was to evaluate the effectiveness of the project-based learning approach as an innovative pedagogical method to improve software engineering students’ skills in three critical domains, namely practical, knowledge, and soft-skills. Seventy students’ skills and knowledge of various aspects of software engineering before and after the learning intervention were compared using the t-test. They were guided to carry out a software engineering project in several groups. Survey questionnaires consisting of close and open-ended questions to probe various aspects of software engineering, namely project planning, requirement analysis, software design, developments, and presentation, were administered to the students after the learning intervention. The results showed the differences in students’ skills and knowledge in the above aspects of software engineering were significant, signifying that the project-based learning––computational thinking approach is an effective approach to help students learn such aspects of software engineering more efficaciously and boost cooperative learning.

Published: March 2024

Students in full-boarding school respond in a variety of ways to the rapid transformation and rearrangement of learning modes during the Covid-19 pandemic. To understand their situation, this paper describes the scenarios and issues that rose in the daily academic activity of the full boarding school students as online learners. A qualitative exploratory research design was used to answer three research questions regarding students’ experiences, problems with, and opinions on online learning during the Covid-19 pandemic. A total of 83 form four students (male and female) from three Ministry of Education full boarding schools in Selangor and Kuala Lumpur were chosen based on purposive sampling. An open-ended survey was used for data collection, while thematic analysis was used to analyse the data. The findings show that experiences faced by students during online learning involved distractions from the environment, freedom in learning and self-exploratory learning. Problems faced by students during online classes were internet disruption, online learning devices and social interaction. Their experiences and problems have an indirect influence on their opinion and preference for online learning. These findings reveal that while children preferred to be in their own home, learning was frequently disrupted by outside factors. Despite having a good academic background, the obstacles faced in online learning by the full boarding school students were similar to those in regular school. In conclusion, intrinsic motivation and self-exploratory learning are important to ensure students are not lagging in academics when it comes to online learning.

In the study of design and development, one of the vital stages that need to be carried out is the needs analysis. In this study, a needs analysis is carried out to ensure that the module produced is suitable for the user's needs. This quantitative survey study was carried out to see the need for the development of the second year Mathematics Neoteric Learning Module in the field of numbers and operations from teachers’ perspective as well as to see teachers’ perception and knowledge about integration between subjects at school. This module uses a new (neoteric) approach that has not yet been widely used in schools. This neoteric approach used is called integrated learning where three subjects are combined in one teaching session. In this study, the subjects chosen are Mathematics, Physical Education and Music Art Education. A set of needs analysis questionnaires was given to 21 primary school mathematics teachers throughout Malaysia. The data obtained were analyzed descriptively, such as frequencies and percentages using software. The results of the analysis show that the majority of respondents agree that this module is suitable for student’s learning. A total of 90.48% of respondents agreed that the development of neoteric learning modules should be developed for the field of numbers and operations. In addition, the findings also show that teachers have knowledge about learning using integration methods where 85.71% of respondents have used subject integration methods during teaching and learning sessions, while a total of 52.38% of respondents have carried out the integration of Mathematics subjects with Physical Education and Education Music art. The results of this study provide a brief overview of the need for a learning module using the neoteric method of integration for Year 2 Mathematics in the field of numbers and operations.

Published: March 2024

Phenol is a widely used non-renewable petrochemical resource in many organic syntheses, hence sourcing phenolic derivatives from renewable resources is an important concern. In this study, a novel monoglyceride (MG) was synthesized utilizing “cardanol” as a starting material, which is an eco-friendly and natural phenolic derivative. Cardanol was obtained by the decarboxylation of anacardic acid present in raw cashew nut shell liquid (CNSL). It was then reacted with maleic anhydride (MA) to synthesize a novel mono-phenyl maleate (MPM) derivative with a purity of 65.5%. This product was subjected to a direct esterification with glycerol to obtain the novel MG. Based on the per-iodic oxidation method, the percentage composition of the monoglyceride was obtained to be 70.1%. It showed high thermal stability up to 250 ℃. This MG being a thermally stable di-functional compound makes it a potential novel monomer that can be used to synthesize novel alkyd resins with enhanced properties in the future.
