Under tropical and subtropical climates, global warming and climate change have a negative impact on the output of cattle and poultry. In hot temperature zones, heat stress is one of the most important stressors affecting chicken productivity, leading to huge financial losses for the poultry sector. The harmful effects of overheating have been reduced by the adoption of several pragmatic approaches. One of these is food manipulation, which is gaining popularity as a natural source of antioxidants, minerals and electrolytes in many parts of the world. According on size, dose, and animal, research in recent years have suggested copper nanoparticles as a possible substitute for antibacterial medicines and a growth booster. An essential element known as copper (Cu) is important for the organism's defense against oxidative stress. Nevertheless, there is little study on the application of The CuO nanoparticles in the poultry sector. The use of plant extracts in the synthesis of metal nanoparticles is a very promising green synthesis technique. One of the most significant issues in the production of poultry is heat stress. The copper oxide nanoparticles may improve bird performance, lower bird temperature, and increase bird tolerance to the harmful effects of high temperature when added to the diet, particularly at 50% of the birds' suggested requirement during heat stress. In the context of current perspectives and a strategic future under conditions of climate change, this review and case study provides an overview of the mode of action, recommended levels of Nano-CuO, and effects on growth performance, nutrient digestibility, carcass criteria, and blood biochemical of broilers.

On citrus leaves, a laboratory trial was conducted to test the effect of several compounds against the nymphs of the cottony cushion scale, Icerya purchasi , under laboratory conditions at Plant Protection Dept., Faculty of Agriculture, Valley University, Qena governorate, Egypt. Two insecticides (thiamethoxam 25% and malathion 57%), mineral oil (active cable 2), three plant oils (clove oil, mint oil and ginger oil) and two plant extracts (garlic and moringa) were used. The results demonstrated that under laboratory circumstances, the investigated substances on I. purchasi were varied. The tested compounds could be descendingly arranged as follows: thiamethoxam 25%, malathion 57%, active cable 2, clove oil, mint oil, ginger oil, garlic and moringa. The corresponding LC 50 values after 72 h. were 0.02, 0.24, 0.91, 3.11, 3.44, 4.17, 31.36 and 35.06 ppm. While, LC 90 values were 0.10, 1.11, 4.56, 6.87, 7.92, 11.36, 121.96 and 178.86 ppm. Also, the insecticidal efficiency of thiamethoxam 25% and malathion 57% showed the highest toxicity against nymphs of scale insect on citrus leaves, while the plant extract, moringa showed the lowest effect.

Royal jelly (RJ) is a yellowish-white acidic glandular secretion produced by worker honeybees. RJ is fed to worker and drone bees in the first three days of their larval stage, but for five days in queen larvae and after development as adult. Globally, RJ is mightily demanded and utilized commercially in supplementary medicines and cosmetics. The present work was conducted to study the impact of pollen trapping of queen less-honeybee, Apies mellifera, colonies on acceptance rate of grafted queen cups, RJ production, i.e., amount per cup, and total colony production. Obtained results showed that non-trapped colonies averaged 54.186% acceptance rate of cell cups /colony, 0.124 mg RJ/ cup, and 3.012 g RJ/ colony, while those deprived of pollens were severely affected, averaged 23.799%, 0.099mg, and 1.073g for the same parameters, respectively. Significant differences between values of trapped and non-trapped colonies were found.

Two field experiments were carried out during the 2019-20 and 2020-21 seasons in private farm at west, El-Minia Governorate, Egypt, to evaluate the effect of using arbuscular mycorrhizal fungi (AMF) on promoting the efficiency faba bean cultivars cultivated in sandy soil to resist drought stress under drip irrigation system. The treatments of the experiment were composed of three irrigation treatments (I 100 : full-irrigation, I 75 : moderate drought, and I 50 : severe drought), two inoculations [+] with AMF and [-] without AMF, and three faba bean cultivars (Giza-843, Nubaria-1, and Misr-1). Strip-split plot design in RCBD with three replications was used. The results indicate that (I 50 ) treatment significantly decreased leaf area index, No. of branches plant -1 , No. of leaves plant -1 , plant height, No. of pods plant 1 , 100-seed weight, No. of days from sowing to maturity, seed yield, and land use efficiency (LUE); increased water productivity (WP), economic water productivity (EWP), NPK%, and seeds crude protein SCP%, relative to (I 100 ) treatment, in both seasons. Inoculation with AMF significantly increased all studied traits of faba bean plants and improved nutrient and water uptake under drought-stress conditions. AMF was increased seed yield by 19.34 and 24.19% compared to un-inoculation in the 1 st and 2 nd seasons, respectively. Giza-843 cv . gave the highest values of plant height, No. of pods plant -1 , No. of days to maturity, seed yield, land use efficiency, WP, EWP, and tolerance to drought stress. The 1 st and 2 nd order interactions were significant in most traits.

The present study was carried out at El-Mataana Agricultural Research Station, Agricultural Research center, Luxor Governorate (Latitude 25°41′N, Longitude 32°39′E) in three crop seasons 2018/19, 2019/20 and 2020/21 (PC, FR and SR) to evaluate stability and ratoon ability of five sugarcane genotypes, namely (G.84-47, G.2003-47, G.2004-27 and C.57-14 compared with the commercial variety GT.54-9) under three-row distances (80, 100 and 120 cm). A strip block design was used. The results recorded that, the new variety G.2004-27 had the high cane and sugar yields followed by the cultivated variety GT.54-9 without significant difference between them only in sugar yield trait, whereas the lowest values were recorded by C.57-14 genotypes. The genotype G.2004-27 and the commercial variety GT.54-9 got their highest cane and sugar yields under 100 cm row distance in SR crop. The commercial variety GT.54-9 and G.2003-47 (new variety) had the 1 st rank of RA under 80 cm row distance for cane yield, while under 100 cm row distance the cultivar GT.54-9 ranked in 1 st where the new variety G.2003-47 ranked in 1 st one under 120 cm row distance in the same trait. Although, the promising variety G.2003-47 was the most stable genotype in cane and sugar yields across tested environments.

In 2018 and 2019 summer seasons form field experiments were carried out at Shandaweel Agric. Res. Station using 15 peanut genotypes to study the genetic parameters like variability, heritability and genetic advance as the percent, in order to develop new varieties. Results showed significant differences for the studied traits in the two seasons and the combined. Lines 11 recorded the highest value for pods weight/plant, 100-pod weight, seeds weight/plant,100-seed weight and pod yield (ard/fed.) in two seasons and their combined. Phenotypic coefficient of variance (PCV) was more than genotypic coefficient of variance (GCV) showed larger influence of environment for all characters with slight differences in few cases. Heritability estimates along with expected genetic advance as percentage of mean was high for number of pods/plant, number of seeds/plant, seeds weight/plant and shelling percentage%, predicting the importance of additive gene action and ample scope for importance in these traits through selection. Correlations study revealed that pod yield (adr/fed) had highly significantly positive correlation with number of pod/ plant, pods weight/plant, 100-pod weight/plant, number of seeds/ plant, seeds weight/plant and 100-seed weight. Path coefficient analysis indicated that pods weight/plant, 100-pod weight and number of seeds/plant had the highest direct effect on pod yield (ard/fed.). Through these studied results and selecting the yield of peanut pods by these traits would be effective, two types of promising lines (No. 6 and 11), can be development varieties with good cultivation in Upper Egypt governorates.

Integrated nutrient management is one of the alternatives to inorganic fertilizer application to sustain ecological balance, and crop productivity and augment the cost of fertilizers. This study aimed to evaluate the response of sweet sorghum to the combined application of poultry litter and inorganic fertilizer on plant height, stalk length, stalk diameter, panicle length, panicle weight, 1,000-grain weight, and plot yield. This was conducted in a farmer's field at Cabadbaran City, Agusan del Norte, Philippines in 2021. The experiment was laid out in Randomized Complete Block Design (RCBD) with six treatments and three replications. The treatments were T 1 - No fertilizer application (control), T 2 - 120-40-45 kg ha -1 N, P 2 O 5 , K 2 O (Recommended Rate), T 3 - 5 t ha -1 poultry litter, T 4 - 90-30-33.75 kg ha -1 N, P 2 O 5 , K 2 O + 1.25 t ha -1 poultry litter, T 5 - 60-20-22.5 kg ha -1 N, P 2 O 5 , K 2 O + 2.5 t ha -1 poultry litter and T 6 - 30-10-11.25 kg ha -1 N, P 2 O 5 , K 2 O + 3.75 t ha -1 poultry litter. The combined application of poultry litter and inorganic fertilizer significantly affected the plant height, stalk length, stalk diameter, panicle length, panicle weight, and grain yield. The highest grain yield was recorded in plants applied with 3.75 t ha -1 poultry litter + 30-10-11.25 kg ha -1 N, P 2 O 5 , K 2 O inorganic (T 6 ) but was comparable with the other poultry litter + inorganic fertilizer treatments. T6 gave the highest net income and return on investment of PhP 63,327.98 and 143.72 percent, respectively. It could be concluded that growing sweet sorghum was highly profitable when applied with a combination of poultry litter and inorganic fertilizer at the rate of 3.75 t ha-1 30-10-11.25 kg ha-1 N, P2O5, K2O.
综合营养管理是施用无机肥料的替代方案之一，以维持生态平衡、作物生产力并增加肥料成本。本研究旨在评估甜高粱对家禽粪便和无机肥联合施用对株高、茎长、茎径、穗长、穗重、1000粒重和小区产量的响应。2021年，这项研究在菲律宾北阿瓜桑省卡巴德巴兰市的一块农田里进行。实验采用随机完全块设计（RCBD），共有六个处理和三个重复。处理为T1-不施肥（对照），T2-120-40-45 kg ha-1 N，P2 O 5，K2 O（推荐速率），T3-5 T ha-1家禽窝，T4-90-30-3.75 kg ha-1N，P2 O5，K2 O+1.25 T ha-2家禽窝，T5-60-20-25 kg ha-1N，P2 O5.K2 O+2.5 T ha-3家禽窝和T6-30-10-125 kg ha-1-N，P2 o5.K2 O+3.75 T ha-1.1家禽窝。家禽粪便和无机肥的联合施用显著影响株高、茎长、茎径、穗长、穗重和粮食产量。施用3.75 t ha-1家禽粪+30-10-11.25 kg ha-1 N、P2 O 5、K2 O无机肥（T6）的植株产量最高，但与其他家禽粪+无机肥处理相当。T6的净收入和投资回报率最高，分别为63327.98和143.72%。可以得出结论，当家禽粪便和无机肥料以3.75 t ha-1 30-10-11.25 kg ha-1 N、P2O5、K2O的比例施用时，种植甜高粱是非常有利可图的。

The agricultural undergraduate curriculum in Nigeria was restructured by the introduction of a practical year program (PYP) for students. This study investigated Students' perspectives, constraints, and strategies for enhancing PYP, as well as the impact of PYP on future career choices. A standardized questionnaire was used to obtain data from students. The data was analyzed with the help of frequency distribution and mean. Students had a favorable (sufficient) opinion of PYP, and they formed a positive attitude toward agriculture as a source of income, according to the findings. Delay in payment of allowances (3.48), difficulties combining agricultural work with lectures (3.08), and insufficient safety equipment to be used by students were among the perceived constraints and mean scores (2.95). The conclusion was reached that addressing undergraduate skill acquisition through the PYP would ensure youth employment in extension organizations and efficient extension service delivery to farmers. This would allow for long-term agricultural development.

Abiotic controls such as Ultraviolet irradiation (UV) and magnetic fields (MF) have a microbicidal effect on the growth survival rate of plant pathogens. Date palm black rot disease is caused by the phytopathogenic fungus Thielaviopsis paradoxa (Th. Paradoxa ), while soft onion rot is caused by the phytopathogenic bacteria Pectobacterium cartovorum ( Pe. cartovorum ). The 100-280 nm peak UV wavelength was employed for (0, 5,10, 15, 20, 25 and 30 minutes). The effect of UV wavelength was used on the above fungi and bacteria on solid nutrient agar (NA) medium and measured the growth number colony forming unit (CFU)/ml) on the Petri dish. The MF Single field strength of 10 gausses was used on a liquid nutrient broth (NB) medium and measured the growth by the optical density (O.D) and CFU for 30 minutes at 28 °C. The results of reduction show best effect for MF at 5 cm was 99%, with a growth rate of 1.1 x 10 2 compared with Pe. cartovourum . The O.D results of Pe.cartovorum at UV ray was 0.09 and colony forming unit 1.5 × 10 7 CFU/ml). At the end of the exposure time of optical density, the (O.D) and CFU were 1.2 and 1.1x10 2 CFU/ml, respectively. When a direct magnetic field is used to induce the fungus colony, it uses a method that is very different from colony formation in a petri dishes. The abiotic elements in this study have an impact on plant pathogen control and are seen as alternatives with an effect on the environment and economy.

This study investigated the levels of selected heavy metals and their potential health risks to consumers within Lokoja metropolis, Kogi State, Nigeria. Fresh pumpkin ( Telfairia occidentalis ) leaves, obtained from major (International, Old Market, Kpata and Lokongoma) markets within Lokoja, were analyzed for copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd), Nickel (Ni) and manganese (Mn) using standard atomic adsorption spectrophotometer. Daily intake of metals (DIM), target hazard quotient (THQ)/hazard index (HI) and target cancer risk (TCR), were then determined to assess the potential health risks of the metals. Concentrations of Cd (0.18 ± 0.02 and 0.16 ± 0.02 mg/kg), Pb (0.08 ± 0.11 mg/kg and 0.05 ± 0.10 mg/kg) and Zn (1.82 ± 0.04 mg/kg and 1.76 ± 0.01 mg/kg) were significantly highest (p<0.05) in vegetable samples from International and Old Markets when compared with Lokonguma and Kpata Markets which were not significantly different (p˃0.05) from each other. There were insignificant non-carcinogenic risks for the metals except for Cd which could pose risks when the daily ingestion rate is tripled. Target cancer risks were in the increasing order Pb

This study has shown that the heavy metals in T. occidentalis poses subantantilly low health risks when consumed moderately except for Cd, Ni and Cu when the daily consumption rate is significantly increased over a life time period. Hence, intensive awareness campaigns are recommended to enlighten farmers/retailers on safer ways of cultivation/handling of green leafy vegetables.","PeriodicalId":34040,"journal":{"name":"SVUInternational Journal of Agricultural Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42241689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
