No full textAt the research field of the College of Forestry, SHUATS, Prayagraj, UP, a field experiment was carried out in the Rabi season from November 2022 to March 2023 to determine the impact of integrated nutrition management on Chickpea (Cicer arietinum L.). The experiment is set up using a randomized block design (RBD), with seven treatments that are duplicated three times using different treatments. The results showed that the highest plant height was 19.80 cm at the 30 DAS (days after sowing) interval, 46.43 cm at the 60 DAS interval, and 52.51 cm at the 90 DAS interval. At 30 DAS maximum number of branches (4.33), 60 DAS maximum number of branches (8.67), and 90 DAS maximum number of branches (12.33), maximum test weight (100 seed, hundred seed weight) (gm) (28.00), greatest grain output q/ha (14.51), highest DAS to flowering (79.14), highest number of pods per plant (no.) (32.27), and highest number of seeds per pod (no.) (2.23). Following the best straw yield per hectare (18.33), the highest harvest index percentage (44.18) and the highest benefit-cost ratio (2:91) were harvested. Maximum net return of 115,255 and maximum gross return of 154,855 respectively. The Treatment T7 outcome with the highest recorded result was 100%VERMICOMPOST + 0%FYM + 0%NPK
An Overview of Reproduction in Insects
No full textReproduction is a fundamental process in all life forms, including insects, in which offspring are produced from the parent organisms. The offspring combines genetic information from each of its parents and is genetically unique. Insects reproduce through both sexual and asexual reproduction, ensuring rapid population increase. Sexual reproduction involves the use gametes from both male and female insects, whilst asexual reproduction permits solitary creatures to lead to genetically identical progeny. Reproductive ecology deals with the study of how physiological characteristics, behavioral, and environmental elements impact on insect reproduction. The complexity of insect reproduction is focused by important processes known as vitellogenesis, which is required for egg development and transgenerational immunity. The i5k initiative planned to sequence more than 5,000 insect genomes to increase our understanding, yet challenges remain due to genome assembly issues and budgetary limitations. Understanding the reproductive morphology and methods of insects, as well as oviposition-related genes, is critical for effective pest management and biological control measures. Insect reproductive research contributes immensely to evolutionary biology, conservation, and agricultural productivity by understanding life cycles, reproductive behaviors, and pollination roles. Insect neurobiology, microbiome and environmental entomology are three most important study fields that will come up with new insights into basic biological processes as well as anticipated pest management and conservation measures in the face of environmental changes in the coming future

Evaluation of Growth Performance and Economic Efficiency of Immature Lohmann Brown Layers Fed Graded Levels of Undeshelled Defatted Moringa oleifera Seed Cake
No full textIn a 22-weeks experiment, the impact and economic efficiency of feeding undeshelled defatted Moringa oleifera seed cake (UDMOSC) to Lohmann Brown layer chicks and pullets were investigated. The study had two phases, focusing on chicks (0-8 weeks) and pullets (9-22 weeks). A total of 150-day-old chicks were randomly assigned to five dietary treatments (0%, 5%, 10%, 15% and 15% with Burgazyme inclusion), each replicated three times, and each replicate containing ten (10) birds in a completely randomised design. Data collected was subjected to analysis of variance (ANOVA) using the GenStat statistical package (2008). In the initial phase, chicks fed dietary UDMOSC consumed less feed but had similar (p ˃ 0.05) final body weight compared to the control group. Chicks fed the control, and 5% UDMOSC gained more weight with better feed conversion. Chicks fed 10% UDMOSC had higher mortality. In the second phase, pullets fed the control diet and 15% UDMOSC with the enzyme (UDMOSC15E) showed significantly higher (p = 0.01) feed intake. Final body weight and body weight gain were notably higher (p = 0.001) in pullets fed the control diet. Feed conversion ratio and mortality rate did not significantly differ (P ˃ 0.05) among treatments. Dietary UDMOSC reduced feed cost per kilogram of body weight gain for starters and pullets. While dietary UDMOSC did not significantly affect starter growth, it lowered total feed cost per bird for starters and pullets except for UDMOSC15E, accruing 20.54 – 27.81%. and 25.39 – 40.19% percentage profit range, respectively. Dietary UDMOSC depressed the growth of starters and pullets, but it was economically advantageous by reducing the cost per kilogram of body weight gain for both groups. The negative impact of dietary UDMOSC on the growth of starters and pullets suggests that including UDMOSC in the immature layer diets should be cautiously approached for economic gain and, therefore, recommended for the pullet stage at an inclusion level not exceeding 10%
Regulation of Physiological and Biochemical Mechanisms Related to Water Stress Tolerance in Barley and Improvement of Growth and Productivity Using Salicylic Acid and Chitosan
No full textThe present investigation aimed to assess the impacts of three Salicylic Acid (SA) concentrations (T2=100, T3=200, T4=300ppm), three Chitosan concentrations (T5=150, T6=225, T7=300ppm) and T8= Salicylic Acid (100 ppm) with Chitosan (150 ppm) mixture in comparison to control treatment (T1) on two barley cultivars Giza126 and Giza 134 under rainfed conditions. Some vegetative and yield traits were recorded, plant height, spike length, number of gains spike-1, number of spikes/m2, 1000 grain weight, biological and grain yield. A split plot design was performed with three replications. The field experiment was conducted in the northern west coast region of Egypt (Marsa Matruh government) under the rainfed conditions during 2019/2020 and 2020/2021 growing seasons. The results showed a direct relationship between increased foliar application and increased yield attributes. Results indicated that Giza 126 cultivar as affected by T4 showed the most desirable values for grains spikes-1 in first season, spikes/m2, biological yield and grain yield during the first and second seasons respectively. In addition, barley cultivar Giza 126 as affected by T3 showed the highest values for grains spikes-1 in second season. On the other hand, barley cultivar Giza 134 as affected by T4 showed the highest values for plant height, spike length and 1000-grain weight in first and second seasons respectively. From results, it can be concluded that the Salicylic Acid (SA) concentration 300 ppm is recommendable for improving the productivity of barley under rainfed conditions of Egypt. To study the potential role of SA and Chitosan on water stress tolerance mechanisms some biochemical and physiological parameters were recorded. Application of SA and Chitosan decreased significantly Reactive Oxygen Species (ROS) measuring by determined the concentrations of MDA and H2O2 especially SA with concentrations 300 ppm (T4). For osmolytes (proline, SSC and SPC), all treatments using SA and Chitosan induced significant increase in osmolytes content compared with control under water stress only in the two studied barley genotypes, except for treatment with Chitosan 225 and 300 ppm in Giza 126 for proline content. Similar results were recorded for antioxidant enzymes activity (CAT, POX and PPO) which showed up-regulation for all treatments compared with control under water stress for the two studied genotypes. On contrast, APX antioxidant enzyme recorded the highest activity in control treatment under water stress only. In general, for all studied treatments comparing with control, application of SA300 ppm and the mixture between SA100 and Chitosan150 ppm were the best treatment for induction of up and down regulation of biochemical and physiological component in the barley cells which is known as defense system against water stress damage

This study highlights the dual importance of achieving high garlic yields with NPK while advocating for the integration of organic and biofertilizers to enhance soil health, reduce dependency on synthetic inputs, and ensure long-term agricultural sustainability
Effect of Doses and Storage Time on Acridity of Irradiated Cocoyam Corms
No full textCocoyam is a stable food commonly eaten by the people of Eastern Nigeria. Its utilization as a raw material for food products is affected by its acridity content. The traditional method of processing cocoyam for consumption is by cooking which is time and energy consuming. Nigeria Colocasia esculenta spp (NCe 001 and NCe 011) and Xanthosoma sagittifolium spp (NXs 001 and NXs 002) were subjected to gamma irradiation of 20, 40, 80, 120 and 150Gy for one hour and stored. The controls samples and the stored irradiated samples were analysed to determine their acridity content. The effect of storage time on the acridity content of the irradiated cocoyam samples was studied. The main and interaction effects of storage time and dosage on acridity content were obtained statistically. The result of the study showed that there was a 50% reduction in the acridity content of the irradiated samples after 28 weeks of storage. A significant impact on the acridity content for all the varieties at above 80Gy was observed from the result of the study. There is limited information on the effect of gamma irradiation dose rate and storage period on the acridity in the four cocoyam varieties found in Nigeria. The main purpose of this study is to determine the effect of gamma irradiation dose rate and storage period on the acridity content of these four cocoyam varieties
Assessment of Gender Inclusion in Credit Utilization among Farmers in Ondo State, Nigeria
No full textThis study evaluates gender inclusion in credit utilization among farmers in Ondo State, Nigeria. The research aimed to analyze the nature of credit accessed, identify factors influencing credit utilization and access, and assess the constraints faced by male and female farmers. Data were collected from 120 farmers using a structured questionnaire and analyzed using descriptive statistics, linear regression, and logit regression models. Findings revealed that male farmers were more likely to access both formal and informal credit than female farmers, with 79.3% of males applying for credit compared to 42.1% of females. Education was a significant factor influencing credit utilization for both genders, while age, marital status, and farm size also positively impacted credit utilization among female farmers. High collateral requirements, complex application processes, and gender bias were key constraints in accessing credit, particularly for female farmers. The study concluded that education plays a vital role in credit access and utilization, with male farmers generally being more advantaged. Recommendations include government-backed empowerment programs and supervised credit schemes to improve credit access for both genders, especially women, and enhance agricultural productivity
Effect of Mulching as a Weed Management Strategy in Field Production of French Beans (Phaseolus vulgaris L) in Western Kenya
No full textThere has been a 2% decrease on French bean (Phaseolus vulgaris L) production in Kenya due to factors such as weeds, pests and diseases and the challenge of controlling them using chemicals that result in high rejection rate or interception in the export market because of chemical residues. The objectives of this study were to evaluate the effect of different mulching materials on the growth and yield of French bean cultivars and to determine the effect of different mulching materials on weed density. Field experiments were carried out at KALRO Kitale, Trans Nzoia county Kenya. Season 1 was carried out during long rains of April and June 2021 and season two during the short rains of August and October 2021. Black polythene and grass mulch were compared with two hand weedings and no weeding in a Randomized Complete Block Design experiment with three replications. Data on growth and yield of French Beans were collected and subjected to ANOVA using GenStat to determine the significant differences between the treatments. The means were separated using Fisher’s Unprotected LSD at 5% significance level. Growth and yield of French Beans was significantly influenced by the treatments (p≤0.05). Plants grown under black polythene and grass mulch had the tallest height and the highest number of leaves and branches as well as number of pods and cumulative pod yield as compared to those that were hand weeded and unweeded. The highest yield of 2138 and 2597 kg/ ha was obtained under black polythene mulch in season 1 and 2 respectively. This was significantly higher than that obtained from grass mulch, hand weeding and unweeding. In conclusion polythene and grass mulch improved growth and yield of French beans and reduced weed density. It is therefore recommended that farmers should adapt mulching as a cultural weed management strategy
