  • Effect of Crop Establishment Methods and Organic Weed Management on
           Nutrient Uptake, Soil Fertility, and Yield of Aromatic Rice (Oryza sativa

      Abstract: A field experiment was carried out during Kharif, 2019 in an organic block of Instructional-cum-Research farm of Assam Agricultural University, Jorhat, Assam, India to evaluate the effects of systems of rice establishment and organic weed management practices on the yield, nutrient uptake, and soil fertility of aromatic rice variety Kola joha. The experiment was laid out in a split-plot design with systems of establishment in the main plot and organic weed management practices in the subplot. The transplanting method of establishment resulted in a significantly higher grain yield of 18.17 quintal/hectare (q ha-1) and nutrient uptake over the direct seeded method. Among the organic weed management practices, the highest grain yield (21.95 q ha-1) and nutrient uptake were recorded with hand weeding at 20 and 40 DAT/DAS which was followed by intercropping of dhaincha and incorporation at 40 DAT/ DAS (16.90 q ha-1). The highest available N content (260.86 Kg ha-1) in post-harvest soil was recorded with intercropping of dhaincha and incorporation at 40 DAT whereas the highest available P2O5 and K2O contents of soil were recorded with hand weeding at 20 and 40 DAT/DAS.

  • Environmental and Health Effects of SONICHAR'S Coal Mining Activities
           in TchirozĂ©rine (Niger)

      Abstract: The environmental challenge is relatively high in an ecologically fragile area like the Sahel, which has to deal with the phenomena of desertification and loss of biodiversity in which the rural, poor population depends on the natural environment for its survival. Indeed, Niger has a coal basin of Iullemneden; this mineral coal deposit has been exploited since 1978 for the production of electrical energy. This implies a challenge of preserving the environment and its natural resources. It is in this context that the present study aims to analyze the impacts of coal mining and its transformation by SONICHAR on the environment, the health of the populations living near Tchirozérine in order to propose preventive measures, reduction and mitigation. In order to achieve this objective, the methodology adopted for the study consisted of surveys, site visits and field observations. Also, samples of wastewater from the company were collected, transported and analyzed. Directive 019 of March 2011 from Quebec, served as a supporting document for the comparison between the activities carried out by the company and the mining standards. The analysis of the company's activities has shown that most of the company's activities do not comply with the mining standards explicitly mentioned in the Quebec Directive 019. All of the impacts on the physical components of the environment are major impacts, thus calling into question their integrity. The soils and the atmosphere are the units most affected by the activities of this plant. The physico-chemical analysis of the water sample taken showed that this water has concentrations of iron (1.9 mg/l) in fluoride (2.32 mg/l), its alkalinity (510 mg/l) and bicarbonate (612 mg/l). This shows that the concentration of these elements exceeds the standards. As for the population, the impact on the latter can be described as medium impact. The inhabitants have a remarkable awareness of the environmental and health risks they incur. With more than 46% claiming to have noticed the deterioration of their health. Even those who do not complain about the deterioration of their health, attribute the cause of certain observed diseases such as eye and lung diseases to the activities of the factory.

  • Evaluation of IPM Modules against Fall Armyworm in Maize through Frontline
           Demonstration and Its Economic Impact

      Abstract: Aim: The present study was undertaken to assess IPM modules against Fall Armyworm in Maize through Frontline Demonstration and its economic impact. Place and Duration of Study: The present study was carried out in Ananthapuramu district of Andhra Pradesh during the period 2020-2023. Methodology: The main objective of frontline demos is to demonstrate recently available crop production and protection technology, as well as their management practices, in a farmer's field in a micro farming setting. The KVK, Reddipalle conducted front line demonstrations on maize throughout rabi seasons of 2020-21, 2021-22 and 2022–2023, as part of annual technical programme of Krishi Vigyan Kendra, Reddipalle, Ananthapuramu district organised 30 FLD locations in KVK operational area of adopted villages. Following a group discussion, a list of farmers was created, and those who were chosen received specialised training in various parts of suggested protection technologies. Results: According to the current results and subsequent analysis of the results, maize reported a higher total (91120 Rs ha-1) when compared to farmers practice (74309 Rs ha-1). The benefit cost ratio was significantly higher in the recommended approach (2.51) when compared to farmers practice (2.12). The higher grain output and better market pricing of the produce may be the causes of the maize demonstration's higher net returns and B: C ratio. Conclusion: The FLD intervention is highly effective among maize farmers with increased net returns of 13618 rupees per hectare. Hence, FLD plays a vital role in dissemination of technology on a community basis when compared to other approaches.
