The objective of the present study is to identify aridity and temperature resistant sweet corn variety candidates and to provide resource material for development of new hybrid varieties. The research was designed as three-peat random blocks experimental design in Siirt and Sakarya locations in 2014, and irrigation application was conducted with drip irrigation method. Mean plant water consumption in control (I100) was 808 mm and 633 mm in Siirt and Sakarya, and the mean irrigation water amount was 684 mm and 138 mm, respectively. The statistical significances of differences among soil moisture content, chlorophyll-meter value, crop water stress index, fresh corncob, and grain yield were investigated. The arid and temperature resistant sweet corn line was determined according to soil moisture content, chlorophyll-meter value, and crop water stress index. The most arid and temperature resistant corn line, variety line #2, had the lowest moisture content and crop water stress index value but the highest chlorophyll-meter value. We found that to determine the arid and temperature resistant corn lines, soil moisture content values can also be used together with chlorophyll-meter values and crop water stress index.

In the current study, gardenia (Gardenia jasminoides Ellis) plants were grown in three growth media; peat moss, clay and rice straw. Acidic wastewater from Manquebad Superphosphate Fertilizer Factory (Assiut, Upper-Egypt) was applied as soil drench (200 ml/pot) at 0, 10, 20 and 30 days. Pots of gardenia were arranged in a complete randomized block design with three replicates and repeated for two successive growing seasons. Peat moss produced the best vegetative and flowering growth of gardenia which could be assigned to its low pH and high organic matter content. Rice straw-grown plants had better vegetative growth than clay-grown ones in terms of plant height, number of leaves, branches and internodes, internode length, fresh and dry weights of shoots and roots, number and diameter of flowers and possessed the highest leaf contents of phosphorus, potassium, cupper and manganese. Plants grown in clay were thicker with bigger leaves resulting in higher total leaf area, and were characterized by the highest shoot-root ratio, more flowers and higher leaf contents of chlorophylls a&b, nitrogen and iron. The application of the acidic water improved vegetative and flowering growth and leaf nutrient content of those plants grown in both clay and rice straw. Increasing the frequency of acidic water application to 10-day interval caused a significant improvement in all vegetative and flowering characteristics and leaf nutrient content. In conclusion, using acidic water at 10-day interval can improve the quality of rice straw and clay to be used as good substitutes for peat moss.

Helen Watson discusses assessing land suitability as often based on finding suitable land for a
specific feedstock. Her concerns include:
The limitations of the Integrated Biodiversity Assessment Tool (IBAT)(Dragisic et al., 2010) for African conditions
The lack of consideration of good management practices in agro-environmental zoning methodology, and the proposed exclusion of slopes steeper than 20% from being zoned as suitable, although such slopes are routinely used in commercial production
The lack of long term, spatially extensive data on the wide range of climatic parameters needed to predict yield performances in particular (1 km2) parcels.
The need for research on what changes in animal migration patterns could follow from climate change, and ensuring that any new fencing for bioenergy projects would not infer with such changes.
The inclusion of archaeologically and historically/culturally significant areas and sites into GIS. Literature on such sites often lacks GPS co-ordinates.

An Agronomic field study was conducted at University of Limpopo Experimental farm, Syferkuil, over two summer growing seasons to determine the optimum phosphorus (P) rate and also assess the productivity of pigeonpea under intercrop with maize. Five P rates (0, 15, 30, 45, and 60 kg P ha-1) were evaluated under sole and intercropped pigeonpea. Treatments were laid out in a randomized complete block design with four replicates. Results revealed that variable P fertilizer rates exerted significant effect on pigeonpea grain yield in both seasons. Highest grain yields of 922 and 1141.7 kg ha-1 under sole and intercrop plots, respectively, were achieved at 45 kg P ha-1 during first and second seasons, respectively. However, the predicted optimum grain yield of 734 and 1034 kg ha-1 based on the response model was achieved at 52.67 kg P ha-1 and 42.84 kg P ha-1, in the respective seasons. Intercropping achieved a significantly higher pigeonpea grain yield (+37%) during second year than sole cropping following P addition; with over 21% mean grain yield advantage across the two planting seasons. Hence, depending on the inherent soil-P level, application of 42-53 kg P ha-1 under pigeonpea/maize intercrop represents the range at which P is optimum for maximum pigeonpea grain yield and better returns for farmers.

Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Identification of water use efficient Napier grass accessions using field drought stress
1. Napier grass (Cenchrus purpureus Schumach L.) is an important perennial forage native to Africa and now introduced and grown in many tropical and
subtropical countries. It is considered as a short-term drought tolerant forage, which is a useful trait in areas with low soil moisture during the dry season,
although it is recommended for planting in areas with rainfall >1,000 mm. In order to exploit the potential of this grass species for improved water use
efficiency (WUE), a field drought stress experiment was conducted with the objective to identify traits that underlie enhanced water use efficiency and to
select best performing genotypes that can thrive in low soil moisture areas.
Identification of Water Use Efficient Napier Grass Accessions
Using Field Drought Stress
▪ Eighty four accessions from ILRI and EMBRAPA
collections of Napier grass were planted using a P-rep
design in four blocks in Bishoftu, Ethiopia.
▪ After establishment plants were exposed to
optimum water (OW) with 20% soil moisture or
water stress (WS) with 10% soil moisture during the
dry season.
▪ Agronomic and physiological data were collected at
every 8 weeks of re-growth.
METHODOLOGY
Fig. 1. Napier grass growing under optimum water (OW, left panel) and water stress (WS, right panel) conditions
▪ The study revealed significant differences between plants grown under optimum water and
water stress (Fig. 1).
▪ Significant genotypic differences were observed among genotypes for morphological and
agronomic traits which suggests selection for improved forage performance will be efficient
(Table 1.).
▪ Genotypes showed significant variation for total dry weight (Fig. 2) and enhanced water use
efficiency (Fig. 3) implying that genotypes differ in economic use of water for increased
biomass production under water limited conditions.
▪ Genotypes showed consistent performance for biomass dry weight and water use efficiency
observed across dry season harvests, indicating promising Napier grass accessions could be
identified for low soil moisture areas forage production.
