It poses a significant threat to both people and animals due to its toxic effects. The potential adverse effects include dermatological injury, immunosuppression, hepatotoxicity, increased risk of cancer, harm to the developing fetus, reproductive disorders, disruption of development processes, neurobehavioral impairments, and particular endocrine disturbances. Furthermore, this chemical has the capacity to influence the process of embryonic development and increase the rates of embryonic mortality. This study aims to investigate the teratogenic impacts of TCDD injection on the head diameter, head shape, body length, and overall body size of Isa brown embryos. The study consisted of three treatment groups: a control group that did not receive any additional TCDD in corn oil, a placebo group that got 5 µL of corn oil, and a treatment group that received five ng/egg of TCDD dissolved in 5 µL of corn oil. The interventions were administered for a duration of seven days. The statistical analysis revealed that the teratogenic effect of TCDD had a substantial impact on the development of thorax circumference, but it did not affect head diameter, head circumference, overall body size, and body length.</strong></p> 2024-01-03T00:00:00+00:00 ##submission.copyrightStatement## https://gphjournal.org/index.php/ar/article/view/881 KNOWLEDGE AND ADOPTION OF PRECISION AGRICULTURE AMONG OIL PALM SMALLHOLDER FARMERS IN AKWA IBOM STATE, NIGERIA 2024-01-04T10:05:58+00:00 Obot Akaninyene P. ap.obot@unizik.edu.ng Okechukwu Frances O. noreplygphjournal@gmail.com Eze MaryAnn O. noreplygphjournal@gmail.com Obot Elizabeth A. noreplygphjournals@gmail.com Udoh Mfon noreplygphjournals@gmail.com <p><strong>Precision Agriculture (PA) deals with the fine-tuned management of crop inputs including seeds, fertilizers, water, pesticides and energy inorder to create savings on these inputs, increase yield, augment profitability and protect the environment. This study was carried out with the aim of knowing the level of awareness of precision agriculture and the various factors affecting the adoption of precision agriculture by oil palm smallholder farmers in Essien Udim rural communities. Eighty respondents were interviewed. The data was analyzed using descriptive analysis such as frequency, percentage, mean and likert scale. The outcome of the study showed that most of the farmers were aware of precision agriculture because most of them had formal education. This means that the level of education of oil palm smallholder farmers could result to a high rate of agricultural technology adoption. </strong><br><strong>On the constraints to the adoption of precision agriculture, the study revealed that lack of capital, information, facilities and low technical knowhow were the major constraints identified by the farmers. </strong><br><strong>Since capital, information, facilities and technical knowhow were the major constraints, the availability of capital and agricultural information devices such as radio and mobile phones would help farmers to make informed decisions about what crops to sow or transplant and where to purchase affordable crop inputs and the market to sell their produce.</strong></p> 2024-01-04T00:00:00+00:00 ##submission.copyrightStatement## https://gphjournal.org/index.php/ar/article/view/1181 Bellucia pentamera, Naudin., in South Sumatra: Up Date of Distribution Data and Insect Host Role 2024-01-09T07:42:02+00:00 Hanifa Marisa gmdiqhan2002@yahoo.com Solfiyeni . noreplygphjournals@gmail.com <p><strong>Distribution data of <em>B pentamera</em>, had been published, and it is found in Palembang, Ogan Ilir, Muara Enim and Pali residences.

Agro-industrial activities in Indonesia generate substantial waste, including cassavapeel, which can serve as avaluable carbohydrate source in fish feed. Cassava is the third most important food crop commodity in Indonesia, and its productivity has been increasing over the years. Cassava possesses a good nutritional profile, with high starch content and energy value. Fermentation of cassava peel can enhance its nutritional value by increasing crude protein content and reducing anti-nutrients such as cyanide acid. Fermented cassava peel products have been shown to reduce reliance on imported feed ingredients and lower production costs without compromising fish growth. The utilization of fermented cassava peel waste presents a sustainable solution for converting agro-industrial waste into a suitable fish feed ingredient.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </strong></p> 2024-02-06T12:16:55+00:00 ##submission.copyrightStatement## https://gphjournal.org/index.php/ar/article/view/1051 Effects of substrate and mycorrhizal inoculum on stem segment cuttings of Pterocarpus erinaceus Poir.

M. noreplygphjournals@gmail.com <p><strong><em>Pterocarpus erinaceus</em></strong><strong> Poir is a woody species of the Sudano-Guinean to Sudano-Sahelian zones with very high food, medicinal and commercial potential leading to the overexploitation. This study aimed to contribute to the domestication of this species using stem segment cuttings. The sand/sawdust and black soil/sawdust substrates were inoculated with 0.10, and 20 g of mycorrhizae. The split plot with 4 repetitions was used as the experimental method and set at 10 cuttings per unit. The experience revealed that the appropriate substrate and dose of mycorrhizae for the budding of stem segment cuttings (SSC) were the sand/sawdust mixture (25.00 ± 18.34 %) and 10 g (23.75 ± 5.63 %) respectively. Satisfactory result was recorded in 10 g (4.18 ± 2.52 cm) dose of mycorrhizae for the height of the aerial axes with abundant number of leaves per aerial observed in the sand/sawdust substrate (2.36 ± 0.48). Concerning the rooting ability of the cuttings, adequate substrate for the number of newly formed roots is the sand/sawdust mixture (25.00 ± 18.34 %) while the dose of 10 g of mycorrhizae favoured the appearance of roots (23.75 ± 14.07 %). The best substrate for the length of newly formed roots is the sand/sawdust mixture (10.64 ± 7.14 cm) and 10 g of mycorrhizae improved the length (9.82 ± 6.40 cm) for Senegal rosewood. Given the above results, we can admit that the improvement of certain parameters (budding, rooting) in P. erinaceus is possible by vegetative propagation.</strong></p> 2024-02-03T00:00:00+00:00 ##submission.copyrightStatement## https://gphjournal.org/index.php/ar/article/view/1205 THE EFFECT OF A COMBINATION OF SOIL IMPROVEMENT AND N, P, K FERTILIZER ON K-POTENTIAL, K-dd, K-UPTAKE, AND YIELD OF LOWLAND RICE (Oryza sativa L.)

Selecting soil types that are not suitable for the type of crop will result in poor crop growth, slowness, and low yields. In the same way that the cultivation of crops in the production of vegetable crops is the same, that is, choosing the type of soil that is suitable for the crop is a point to consider and pay attention to. Due to some geographical areas in some communes, the topography is sandy or rocky, and the soil is hard, making it difficult for farmers to prepare parallel cultivable land where some people have less land and try to cultivate it using plastic buckets. Cement or bags to grow as a vegetable or grow to get some yield just to meet daily food needs; avoid spending money to buy vegetables from the market. Bak Choy is a crop that can grow on almost any type of soil, especially alluvial soils. It also has many benefits for the body, such as strengthening bones, the immune system, cancer cells, and so on.
