Cocos nucifera L. is an important coastal crop in Côte d'Ivoire, with 53 coconut cultivars. The present study was carried out to compare the morphophysical characteristics of C. nucifera L. fruit of the improved parents Rennell Island Tall (RIT+) and West Africa Tall (WAT+) and their hybrids PB113+ and PB121+, harvested at different maturity. The ANOVA results showed that cultivar and maturity had a significant effect (p < 0.05) on all morphological characteristics studied, except for sphericity, H2, H3, and H4 where maturity was not statistically significant (p ≥ 0.05). The morphological parameters of RIT+ coconuts were statistically different from those of WAT+, PB113+ and PB121+ (p < 0.05). The WAT+ coconuts had high kernel thickness. The hybrid PB121+ was more spherical than other fruits and had a higher shell thickness. Improved Rennell Island Tall as a parent had good kernel water mass and large shape, while the improved West Tall Africa had good kernel thickness. Concerning PB113+ and PB121+ hybrids, they were similar in dimensional parameters. However, PB121+ fruits had the highest mass and volume, kernel mass, and shell mass compared to PB113+. This study showed variabilities between the improved cultivars WAT+, RIT+ and the PB121+ and PB113+ hybrids. Key words: Cocos nucifera L., fruit, cultivar, maturity morphological, Côte d’Ivoire, germplasm.

Several maize varieties with high-yield potential have recently been created; however, their resistance to storage pests is unknown. This study compares the resistance ability to Sitophilus zeamais of four open-pollinated varieties (OPVs) and thirteen hybrid maize varieties using Dobie's susceptibility index (SI). The genotypes were tested in a completely randomized design with three replications at a temperature of 28°C and a humidity of 65 to 70%. A resistant OP maize variety (Melkassa 6Q) had SI of less than 3.5 (3.43). OPVs evaluated (Gambela, Gibe 2, and Gibe 3) had SI of 4.60, 5.32, and 6.77, respectively, while most hybrid varieties had SI of 3.82, 4.15, 4.22, 4.65, 4.74, 4.92, 5.17, 5.74, 6.00, 6.50, and 7.37 respectively. These include BH547, AMH851, P3812W, HB30G19, MHQ138, SC627, BH546, P3506W, BH549, P2859W, and AMH850. Among the thirteen hybrids, AMH853 had a SI of 8.13. This susceptible variety produced a high number of F1 progenies (2.19), had a low median developmental time (27 days), a high percentage of seed damage (75.00%), a high production of grain dust (0.92 g), a high percentage of seed weight loss (1.1%), and a low percentage of weevil mortality (0.16%). Subsistence farming in developing countries should encourage resistant varieties. Key words: Maize varieties, progeny emergence, susceptibility index, weight loss.

The study analyzed the input-output relationship of crop enterprises in response to different climate change adaptation options among farmers in Borno State, Nigeria. The research was conducted in two agroecological zones (AEZ) within the state, employing a multi-stage sampling procedure to select 360 farmers for the study. Data analysis involved the use of means, frequencies, and multiple regression techniques. The results regarding adaptation practices in the respective AEZs revealed that in the Sudan AEZ, farmers primarily employed strategies such as multiple cropping (98.9%), early planting (63.9%), mulching/use of cover crops (36.1%), and increased fertilizer application (25.00%). In the Guinea AEZ, the most widely used adaptation strategies included multiple cropping (93.30%), utilization of new crop varieties tolerant to the evolving climate (72.20%), increased fertilizer application (47.20%), and the use of herbicides (25.00%). The production function analysis results demonstrated that approximately 85, 51, 53, 57, 81 and 65% of the variations in yields resulting from climate change adaptation strategies, such as the application of herbicides, utilization of organic manure, early planting, increased fertilizer application, mulching, and the use of cover crops, as well as the use of improved crop varieties tolerant to the new climate regime, were accounted for by the inputs. Furthermore, the coefficients of production inputs were significant and positively correlated with crop yields across different adaptation strategies and at various levels. In conclusion, the study found that farmers primarily employed technically-based adaptation strategies, and production inputs played a crucial role in determining crop yields across various adaptation approaches. It is recommended, among other measures, that adaptation materials be provided to farmers at a subsidized rate. Key words: Input-output, crop enterprises, climate change, adaptation strategies, Borno State.

The State of Goiás is the second-largest producer of sugarcane in Brazil. However, it still faces low productivity, primarily due to the lack of sugarcane varieties adapted to this region and its typical water deficit. Therefore, the objective of this work is to evaluate the performance of two sugarcane varieties subjected to different irrigation management practices in the Cerrado of Goiás. The study was conducted at the Federal University of Goiás (UFG) in the experimental area of the School of Agronomy. The experimental design utilized a completely randomized block arrangement in a split-plot design with four replications. The treatments consisted of two sugarcane varieties (RB 92579 and RB 855156) and three irrigation management methods: Rainfed, optimal water range-based and conventional (based on available soil water). These treatments had significant effects on the technological attributes of sugarcane in the Cerrado region of Goiás. Notably, sugarcane plants of the RB 92579 variety exhibited the best results when subjected to irrigation management based on the optimal water range.

Developing salt tolerant varieties is the best solution to the increasing soil salinity problem of rice growing areas all over the world. This study evaluated salinity tolerance of 72 lowland rice genotypes at the reproductive stage in field experiments conducted in coastal Marovoay, Madagascar. Field salinity levels were controlled at 2 and 4 dS m-1 through irrigation. Tolerance of selected genotypes was validated in pot experiments with salinity levels of 0, 4 and 8 dSm-1. Plant height, panicle number and length, panicle and spikelet fertility, straw weight and grain yield were measured together with visual scores of salt injury. Field salinity strongly reduced panicle number and spikelet fertility, reducing grain yield to 10 g m-2 in sensitive genotypes compared to 60 g m-2 in tolerant genotypes. Thus, 20% of genotypes were classified as tolerant, 50% as intermediate and 30% as sensitive to salinity. Four genotypes IR55179, MTM13_1, MTM13_3, MTM13_5, were confirmed as highly tolerant in the pot experiment. Higher spikelet and panicle fertility in tolerant genotypes contributed to their superior grain yield under salinity. These genotypes can serve as donors to improve grain yield of local varieties sensitive at the reproductive stage, possibly using spikelet and panicle fertility as selection criteria. Key words: Salinity, reproductive stage, growth parameters, salt tolerance, genotypes.
发展耐盐品种是解决世界各地水稻种植区土壤盐渍化问题的最佳途径。本研究在马达加斯加沿海Marovoay进行了田间试验，评估了72个低地水稻基因型在生殖阶段的耐盐性。通过灌溉将田间盐度控制在2和4 dS - m-1。在盐浓度为0、4和8 dSm-1的盆栽试验中验证了所选基因型的耐受性。测定株高、穗数和穗长、穗和小穗肥力、秸秆重和籽粒产量以及盐害视觉评分。田间盐度强烈降低了穗数和小穗育性，使敏感基因型的籽粒产量降至10 g - m2，而耐盐基因型为60 g - m2。因此，20%的基因型为耐盐型，50%为中等型，30%为敏感型。盆栽试验证实，IR55179、MTM13_1、MTM13_3、MTM13_5 4个基因型具有高耐受性。耐盐基因型的高穗、高穗育性是其在盐胁迫下高产的主要原因。这些基因型可以作为供体，在繁殖阶段提高地方敏感品种的产量，可能以小穗和穗育性作为选择标准。关键词:盐度，繁殖阶段，生长参数，耐盐性，基因型

Cricket farming is an upcoming enterprise to most households in rural communities. Apparently, there is no documented evidence on how farmers access agricultural information on cricket value chain. This study was carried out to assess the use of information communication technologies (ICTs) by farmers to access value chain information. ICTs application in cricket farming means ease to access cricket value chain information and improved interaction between cricket farmers and stakeholders. The study adopted an exploratory mixed method research design by use of a structured questionnaire and focus group discussions to collect data. The data was analyzed by using both descriptive and inferential statistics. Quantitative data was analyzed and interpreted using the R-statistical software. Qualitative data was analyzed thematically by drawing meanings from themes thereof. The results showed that the most sought information was cricket rearing practices and the least was market prices for cricket products. Radio was found to be the most significant ICT channel used (p?0.05). However, most farmers complained of poor infrastructure which made it difficult for them to utilize the ICTs effectively. The outcome of this study informs stakeholders on information needs of farmers and the challenges they face while seeking for information. Key words: Cricket, farming, value chain, information, communication, technologies, integration.

Zimbabwe’s cut flower industry has declined over the past years. We determined the national competitiveness of Zimbabwe’s cut flower industry using Porter’s diamond model of competitive advantage in 2018 using a descriptive and exploratory design that made use of qualitative and quantitative research methods. Low numbers of key players in the industry forced researchers to administer questionnaires to only 20 respondents comprising growers, marketers, florists, and associations. There was a relationship between factor conditions and national competitiveness (Chi-square 47.9728; df = 25; and p <0.0029). There was no significant relationship between strategy and national competitiveness (Chi-square 21.3916; DF 15; p-value > 0.1248). There was a relationship between government and national competitiveness (Chi-square 20.6350; DF 10; p-value 0.0238). There was no relationship between chance and national competitiveness (Chi-square 6.8190; df 5; p-value =0.2344). Strategy, structure, rivalry, demand conditions, related and supporting industries, and chance had no statistically significant relationship with the national competitiveness of the industry. Centralised decision making and lack of government intervention make the industry fail to be competitive. To revive the industry, the availability and utilization of factor conditions, particularly skilled marketing personnel, should be increased. Government policies should support the industry so that it is competitive. Key words: Cut flower, government policies, land reform, competitiveness, Porter’s model.

Common bean (Phaseolus vulgaris L.) is an important crop with the potential to curb malnutrition in Sub-Saharan Africa (SSA). However, poor soil fertility is considered to be the major constraint for bean production in SSA. This study determines canopy spread, chlorophyll content, stomatal conductance, and seed yield of common beans in a field experiment conducted at Fumesua (rain-forest) and Akumadan (forest–savannah transition) agroecological zones. The study was conducted in the 2018 and 2019 cropping seasons using a split-plot arranged in a randomized complete block design with three replicates. The treatments consisted of the main plot factor namely varieties (Lv. “Semanhyia” and “Ennepa”) and the sub-plot factor P (75 kg ha−1), NPK (100 kg ha−1), ACARP organic fertilizer (4 t ha-1), ACARP plus NPK (2 t ha-1 + 50 kg ha-1), ACARP plus P (2 t ha-1 + 38 kg ha-1) and control (zero-amendments). Results showed that co-application of P, NPK, and ACARP fertilizer increased plant height and canopy spread by ≈9.54 and 11.25% compared with their sole application and the control, respectively. Similarly, the combined application of the organic and inorganic fertilizers increased chlorophyll content and stomatal conductance by 36.43 and 23.79% compared to their sole application and the control respectively. These observations translate into increased crop biomass and therefore seed yield (≈ 42.54 - 46.58%). A significant variety and nutrient interaction were observed in the number of pods per plant and seed yield, irrespective of the location. The results suggest that the growth and yield response of the crop may be optimized with the co-application of both P, and NPK with ACARP organic fertilizer.

菜豆(Phaseolus vulgaris L.)是撒哈拉以南非洲(SSA)地区具有抑制营养不良潜力的重要作物。然而，土壤肥力差被认为是制约非洲大豆生产的主要因素。本研究在Fumesua(热带雨林)和Akumadan(森林和稀树草原过渡)农业生态区进行大田试验，测定了普通豆的冠层铺展、叶绿素含量、气孔导度和种子产量。本研究于2018年和2019年两季进行，采用3个重复的随机完全区组设计。各处理由主要样地因子即品种(Lv;“没有,Semanhyia”和Ennepa”)和子地块因子P (75 kg ha&负1)、NPK (100 kg ha&负1)、ACARP有机肥(4 t ha-1)、ACARP加NPK (2 t ha-1 + 50 kg ha-1)、ACARP加P (2 t ha-1 + 38 kg ha-1)和对照(零修正)。结果表明，P、NPK和ACARP配施比单独施用和对照分别提高了9.54%和11.25%的株高和冠层铺展。有机肥与无机肥配施使叶绿素含量和气孔导度分别比单施和对照提高了36.43%和23.79%。这些观察结果转化为作物生物量的增加，因此种子也增加了。收益率(≈42.54 - 46.58%)。品种和养分相互作用显著;观察到的是每株豆荚数和种子产量，与地点无关。结果表明，磷、氮磷钾与ACARP有机肥配施可优化作物生长和产量响应。关键词:作物生产力;施肥;作物生理;
