“…In many conditions, differences in methane emission rates were not proportional to differences in methane source, indicating differences in transport capacity among rice cultivars. Previous studies (Borah & Baruah 2015) confirmed this conclusion, finding that differences in methane emissions among different cultivars could be attributed to variation in MTC and substrate producing potentials of each cultivar. As pointed out by Epule et al (2011), the main vectors behind methane emissions from paddy rice fields are methanogenic bacteria, methane fluxes were correlated positively and negatively with methanogens and methanotrophs abundance, respectively, but not correlated with any apparent plant growth parameters.…”

“…In addition, low soil fertility has also been reported as a limiting factor on crop yield (Efretuei et al 2023). Recent studies in Nigeria have shown that crop productivity (within an environment) can be improved with the use of precise agricultural technologies and the selection of the right cultivars (Akpan et al 2022;Ekwere and Efretuei, 2020;Eseme et al, 2019;Jonah et al 2023). Vashi et al (2018) found a positive correlation between growth attributes-tiller numbers, vine length, (influenced by a crop environment), and fresh weight of yam tubers.…”

White guinea yam is a chief source of carbohydrate in West Africa. Knowledge of the relationship between its agronomic traits and tuber yield can contribute to improving management practices and selecting the right cultivars for optimum yield. Field experiments were conducted during the 2021 and 2022 early cropping seasons at the Teaching and research farm of the Akwa Ibom State University, Obio Akpa Campus, to study the agronomic and yield traits of some white guinea yam cultivars. The experiment consisted of eight cultivars of the white yam (TDr 0900135, TDr 0900295, TDr 1401593, TDr 1401785, TDr 1100180, TDr 110028, TDr 1401220 and TDr 8902265) and a local variety, Atam. The experiment was laid out in a randomized complete block design and replicated three times. The effect of cultivars on growth and yield parameters were determined using a one way ANOVA and the relationships between growth and yield parameters were determined using Linear regression and Pearson Correlation Coefficient. There were significant differences among the yam cultivars in number of leaves produced per plant, number of tubers per plant and fresh tuber yield (tons/ha). Cultivar TDr 8902665 and TDr 140220 performed better than other cultivars in yield (8.05 and 8.91 tons/ha in 2021 and 8.42 and 8.85 tons/ha in 2022). The local variety, Atam sprouted late and also produced a low yield (6.8 tons/ha) compared to most cultivars. Across cultivars, there was a positive relationship between leaf number and tuber yield and vine numbers and tuber length- leaf numbers could significantly predict tuber yield and no of vines, tuber length. Cultivars TDr 140220 and TDr 8902665 have shown potential to outperform the other cultivars tested in this study. Yam farmers may adopt these varieties for cultivation in this study area.

“…Small and marginal farmers (land holdings of less than 2 hectares) dominate Indian agriculture, accounting for 82 percent of the overall farmer population. Agriculture accounts for 49 percent of the overall population's output [3,4]. Rice is India's most significant cereal food crop, accounting for around 24% of the country's gross planted area.…”

Field experiments were conducted for four consecutive Kharif season of 2017-2020 at Organic Farming Research Centre, Sher-e- Kashmir University of Agricultural Sciences and Technology of Jammu, Chatha, located at 320 66' North latitude and 740 79' East longitude with an altitude of 356 meters above mean sea level in the Shiwalik foothills of North-Western Himalayas. The mean annual rainfall of the experimental site is 1198.2mm of which 70-75% rainfall is received from June to September. The soil of the experimental site was sandy clay loam in texture, slightly alkaline in reaction, medium in organic carbon, available phosphorus and potassium but low in available nitrogen. The experiment was laid out in split plot design with three replications. The experiment consisted of 05 (five) organic nutrients sources treatments with two crop establishment methods. The results showed that there were maximum plant growth characters of organic Basmati 370 like plant height, number of tillers, number of productive tillers, root length, number of roots, root volume, biological yield etc after using vermicompost @ 3.0 t ha-1 followed by FYM @ 8 t ha-1 under SRI method. In addition, SRI method was found to be effective in reducing pest and disease incidence, shortening crop rotations and improving plant conditions. It was found from the study that among the various treatments of organic nutrient sources, the highest (132.13 q/ha) biological yield of basmati 370 was recorded with the application of vermicompost @ 3t/ha which was statistically at par the application of FYM @ 8t/ha (130.20q/ha) respectively under SRI method.
