The experiment was conducted in the field for 13 months (June 2019-july 2020) in Abongoua in the department of Bongouanou (East-central Côte d'Ivoire). After the cleaning of a 900 m2 surface of a fallow of more than 5 years, and cleared of all plant debris, soil samples were taken with an auger in the 40 cm surface in each corner and in the center of the experimental plot to constitute the composite sample for laboratory analysis. The trials were conducted in a randomized complete block design with four replicates in which four elementary plots were distributed. Three treatments T1 (tilled soil), T2 (mounded soil) and T3 (ridged soil) compared to a control treatment T0 (no-till soil) were applied in each microplot. The cuttings were directly sown at a rate of 12 cuttings per treatment. The data of the different parameters collected underwent an analysis of variance (ANOVA) performed with SAS software version 9.4 and the means were separated using the Newman and Keuls test at the 5% probability threshold. The results showed an acidic soil with a sandy texture and a good supply of nutrients, particularly major elements, trace elements and clay-humus complex. Good growth and development of agro-morphological parameters as well as yield were obtained with treatments T3 (ridged soil), T2 (mounded soil) and T1 (tilled soil) in decreasing order of importance compared to the control treatment (T0). In conclusion, the study clearly showed that the type of tillage, particularly the ridged tillage technique, improves the agro morphological parameters, productivity and yield of cassava. What we recommend to farmers for a good yield of cassava in the area.</p> 2021-10-06T00:00:00+00:00 ##submission.copyrightStatement## Decomposition of Plantain Peel Powder and Assessment of its Effects on Soil Physical and Chemical Characteristics 2021-10-14T01:55:51+00:00 Alla Kouadio Théodore Gbeze Kpata Hermann Roland Bomisso Edson Lezin <p>This study aims at assessing the effects of plantain (<em>Musa</em> <em>paradisiaca</em>) peel powder on soil physical and chemical properties in the context of sustainable yield management. The experiment took place in the laboratory of plant physiology of the University Félix Houphouët Boigny from July to November 2020. Three designs were set up. Design 1 consisted of 20 g of plantain peel powder added to a 2-cm thick layer of sea sand. Design 2 consisted of 5 g of plantain peel powder added to 250 g of sea sand. Design 3 consisted of a homogeneous mixture of 100 g of peel powder and 200 g of rhizospheric tomato or plantain soil. The designs were regularly watered with distilled water. In the first two designs, the plantain peel powder was added according to two methods. These included surface incorporation and deep incorporation. The experiment allowed us to characterize peel powder decomposition and assess its effects on soil physicochemical parameters. The physico-chemical characteristics of the soils were subjected to a one-way analysis of variance (ANOVA 1). STATICA 7.1 software was used to perform all the analyses. Analysis of the results showed that the incorporation method does not influence peel powder decomposition. This decomposition is followed by the release of colored elements. Water retention capacity as well as particle size were improved. The results showed that plantain peel powder is an important source of minerals mainly phosphorus and potassium. It emerges from this study that plantain peel could be a good organic fertilizer for profitable and environmentally friendly agriculture.</p> 2021-10-11T00:00:00+00:00 ##submission.copyrightStatement## Varimax Rotated Principal Component Analysis of Productive Traits in Nigeria Indigenous Cattle Raised under Semi-Intensive Management System 2021-10-19T05:22:36+00:00 D.

Media culture and hydroponics has been used sporadically throughout the world in rooftop and tissue culture also has been used&nbsp; the world as commercial means of growing both food and ornamental plants. It supplies fresh vegetables in countries with limited arable land as well as in small countries with large populations. Plants grown by hydroponics have concisely superior quality, high yield, rapid harvest, and high content, at present it is used widely in research facilities as a technique for studying plant nutrition. Gravel or sand is sometimes used in soilless systems to provide plant support, and retain some nutrients and water. The retention and water can be for their improvement through the used materials, but others&nbsp; such as rice hulls, bagasse, sedge peat, and sawdust are used sometime as constituents in soilless mixture straw bales have been used as the growing medium in England and Canada. Rockwool (porous stone fiber) is used in Europe. Since the major constituent of the media in artificial growing systems may be solid or liquid, it is appropriate to use the term soil culture in reference to this general type of growing system and reserve the term hydroponics for those in which water is the principal constituent. Soilless organic media preparation and use has a tremendous effect in land less culture. It is basically used in Rooftop vegetable cultivation.</p> 2021-10-21T00:00:00+00:00 ##submission.copyrightStatement## Analysis of the Effects of Climate Change on Maize Production in Mali 2021-10-29T02:34:17+00:00 Abdoulaye Maïga Moussa Bathily Amadou Bamba Issoufou Soumaïla Mouleye Mamadi Sissako Nimaga <p>The objective of this paper is to analyze the effects of climate change on maize production in Mali during the period 1990-2020. The unit root test (augmented Dickey-Fuller) was used to check the order of integration between the variables in the study. The ARDL (autoregressive distributed lag) approach to cointegration limits is applied to assess the association between the study variables with evidence of a long-term relationship. The unit root test estimates confirm that all variables are stationary at the combination of I(0) and I(1). The results show that precipitation and temperature in June and July have a negative and highly significant effect on maize production in both the short and long term analyses. Among other determinants, the area of land devoted to maize crops and GDP per capita have a positive effect on production. The estimated coefficient on the error correction term is also highly also highly significant As Mali's population grows, in the coming decades the country will face food security challenges. Possible initiatives are needed to configure the Malian government to address the negative effects of climate change on agriculture and ensure adequate food for the growing population.</p> 2021-10-26T00:00:00+00:00 ##submission.copyrightStatement## Evaluation of the Agromorphological Determinants of the Spread of the Bacterial Disease in Orchards of the Main Mango-Producing Regions in Côte d'Ivoire 2021-10-30T02:42:38+00:00 Brou Kouassi Guy Doumbouya Mohamed Oro Zokou Franck Doga Dabé Yapo N'guéssan Patrick Kouassi Koffi II Nazaire Dogbo Denezon Odette <p>The use of agroecological practices for the management of phytosanitary problems has become a major issue in the context of sustainable development. It is with this in mind that this study was initiated in the regions of Bagoué, Poro and Tchologo. This study consisted of investigating the determinants likely to promote the spread of the bacterial disease in 720 mango trees of the Kent variety distributed in 20 orchards in the regions of Poro, Tchologo and Bagoué. During this study, the incidence and severity of bacterial disease on leaves and fruits (IsFe, IsFr, IcFe, IcFr) as well as agromorphological parameters such as East-West and North-South spans, total leaf area, fruit load, trunk circumference, total height and number of main branches (En EO and NS, SFT, ChFr, CirTr, HaTr and RamP) were measured. The performance of the pearson correlation test revealed that spans (N-S and E-O), HaTr, SFT and ChFr are the 4 agromorphological determinants that promote the spread of bacteriosis in orchards of the three (3) regions. The synthesis of the results of the ACP and the CAH supplemented by a multivariate analysis (MANOVA) made it possible to structure the mango orchards into three (3) homogeneous groups. Group 1 orchards (VB4, VB8, VS1, VF5, VK1, VB7, VF2 and VK2) expressed the lowest severity indices and the incidence of bacteriosis on the leaves (respectively 15.21 ± 8.87% ; 12.21 ± 6.54%) and fruits (respectively 13.11 ± 4.75%; 10.40 ± 2.93%). These orchards featured mango trees with medium trunk circumferences (99.14 ± 17.24 cm), medium trunk heights (145.29 ± 7.24 cm) and smallest spans (6.85 ± 1, 13 m for the NS span and 6.79 ± 1.18 m for the EO span) and total leaf area (15.61 ± 0.06 cm). These results could help develop an agroecological control strategy for the sustainable management of bacterial disease.</p> 2021-10-27T00:00:00+00:00 ##submission.copyrightStatement## Influence of Downward Tapping Delay on Agronomic Parameters of Upward Tapping Rubber Trees 2021-11-08T04:16:56+00:00 Moro Affia Perpétue Kouakou N’ guessan Kan Pulchérie Diarassouba Moussa Adou Bini Yao Christophe Konan Djezou Koffi Antoine Kouakou Tanoh Hilaire Obouayeba Samuel <p>The nine-year period of downward tapping prior to upward tapping is often considered too long and irrelevant. Thus, a study was carried out to determine the minimum time needed for downward tapping for which the agronomic parameters (rubber production, vegetative growth) of the rubber trees could best be expressed in upward tapping. Clones with slow (PB 217 and IRCA 41), moderate (GT 1) and fast (PB 260 and IRCA 18) metabolisms were used as plant material in the experiments carried out in Gagnoa, Bettié, Daoukro, San Pedro and Divo. The rubber trees were tapped in a half-spiral downward direction at different times followed by quarter-spiral upward or upward tapping. The experimental design was a Fisher block design with 9 treatments and 4 replications. The results showed that upward tapping preceded by downward tapping for 5 and/or 6 years was the best regardless of the metabolic activity class of the clone. Rubber production expressed in kg.ha<sup>-1</sup>. year<sup>-1</sup> [Slow (5y-2675 ± 79) (6y-2488 ± 59) (T9y-2238 ± 45); Moderate ((5y-5417 ± 127) (6y-5094 ± 141) (T9y-3993 ± 58); Fast (5y-5210 ± 239) (6y-4733 ± 500) (T9y-3723 ± 245)] resulting from these upward tappings increased with an increasing gradient of clone metabolism without, however, detrimental to vegetative growth (cm. yr<sup>-1</sup>) [Slow (5 yr-3.90 ± 1.27) (6 yr-4.05 ± 1.48) (T9 yr-3.40 ± 1.13); Moderate ((5 yr-3.02 ± 0.25) (6 yr-2.80 ± 0.05) (T9 yr-2.39 ± 0.02); Fast (5 yr-4.27 ± 0.42) (6 yr-3.97 ± 0.28) (T9 yr-3.60 ± 0.05)]. These results show that upward tapping in year 6 is more advantageous than tapping in year 10.</p> 2021-11-03T00:00:00+00:00 ##submission.copyrightStatement## Determining the Coping Strategies towards Household Food Security Practiced by the Farmers in Flood Prone Areas 2021-11-08T04:16:36+00:00 M. E. Haque M. N. Islam M. J. Alam M. Y. Uddin M. M. Haque M. R. Islam M. A. Majid M. G. Mostafa N. Muhammad M. Z. Turin <p>A study was carried out at each of three flood affected reverine villages of three upazilas (small administrative unit) under Jamalpur district in Bangladesh during September, 2011 to May, 2012 to find out the coping strategies towards household food security practices by the farmers during flood period. Data were collected from randomly selected 336 respondents of 6720 farm families through both the qualitative and quantitative techniques and analyzed with the help of SPSS. A three-point rating scale was used for measuring the coping strategies considering five components such as food preservation, food management, food collection, agricultural products protection and some social aspects. The overall situation about practicing coping strategy had medium to high level where 70.83 percent were practiced high, 29.17 percent medium and none of them were under practiced low coping strategy towards household food security. Based on the above findings, it can be said that still now there is an ample scope for the development workers to work with the flood affected people for creating awareness towards better utilization of existing resources for improving their food situation as well as livelihoods.</p> 2021-11-03T00:00:00+00:00 ##submission.copyrightStatement## Agrophysiological Characterization of Maize (Zea mays) Plants from EV 8728 Seeds Irradiated to Gamma Radiation 2021-11-09T04:25:14+00:00 Ayolié Koutoua Beugré Manéhonon Martine Kanga Ahou Nadia N’guessan Affoué Sylvie Rachelle Kanga N’guessan Martial Kouadio Kouamé Léonard Kouadio Akéssé Blaise Koné Sié Kissomanbien Kouadio Yatty Justin <p>Maize (<em>Zea mays</em> L.) is a tropical annual herbaceous plant of the Poaceae family. It is a cereal cultivated under very varied conditions ranging from tropical to temperate climates. However, the accentuated climate change causes abiotic and biotic stresses reducing the development and the production of the plants. To improve these plants, it is important to understand the mechanisms involved in these stresses. Two doses of gamma irradiation (200 and 300 grays) were applied to the seeds of a variety (EV8728) of maize grown on an experimental plot at the Jean Lorougnon Guédé University (UJLoG). Thus, the morphological, physiological and biochemical behaviors of the plants were evaluated. The results showed that gamma radiation significantly reduces morphological parameters. However, this reduction is accentuated at 300 grays. At the physiological and biochemical level, the radiation reduced the chlorophyll a, b and total (t) contents and the carotenoid content. Additionally, the contents of proline, total protein and total sugar increased with 200 grays and decreased for 300 grays. However, the phenolic compounds content increases with the irradiation dose.</p> 2021-11-05T00:00:00+00:00 ##submission.copyrightStatement## Effect of Gamma Irradiation of Seeds on the Development and Productivity of Three Maize Varieties (Zea mays.

This variability threatens the production of cash crops such as maize (<em>Zea mays</em> L). Maize is a cereal and has become one of the main agricultural crops in Côte d’Ivoire. The objective of this study is to determine the agro-morphological characteristics of three (03) varieties of maize (EV 8728, GMRP / 18 and MDJ) which have undergone irradiation with gamma radiation (0, 100, 200 and 300 grays) to induce mutations. The agro-morphological evaluation was carried out in a completely randomized block device. morphological characters selected from the descriptors of maize were used in this study. The descriptive analysis revealed a significant diversity between the treatments. The comparison between all the agro-morphological characters and the different treatments showed that the treatments EV8728_0 and EV8728_100 Gy had the best characteristics of ears and grains and the treatment MDJ_200 had the best vegetative characteristics.</p> 2021-11-20T00:00:00+00:00 ##submission.copyrightStatement##
