Abstract:
An experiment was conducted in order to identify the productive genotype of turmeric for the plains of Nepal. In 2017 and 2018, seven promising turmeric genotypes (CI 0207, CI 0205, CI 9102, CI 1312, CI 0503, CI 0507, and CI 0201) were compared with KKH-1 in a Randomized Complete Block Design with four replications at the Directorate of Agricultural Research, Tarahara, Nepal. The plants were 30 cm x 30 cm apart, with 40 plants per 3.6 m2 plot area. Cultural practices were followed in accordance with the recommendations. Analysis of variance, correlation, cluster, and GGEbiplot analysis were performed on the observed data. From the pooled analysis of two years of data, the results showed significant differences in plant height and fresh rhizome yield among genotypes. The rhizome yield of KKH-1 was found significantly higher (19.36 t ha-1) than CI 0205 and CI 9102 and at par with other genotypes. Weight of mother rhizome had significant positive correlation (r = 0.602**) with yield of fresh rhizome. Though KKH-1 yielded the highest fresh rhizome, the cluster and GGEbiplot analysis identified CI0207 as one of the potential turmeric clones next to KKH-1.

Abstract:
Spirulina is a nature’s present as extremely good meals to mankind. It is a photosynthetic filamentous microalga which has emerged as a amazing meals complement because of its wealthy micro- and macronutrient contents. The frame of Spirulina is smooth and with vulnerable mobileular wall that makes it effortlessly digestible. It is a precious supply of proteins, vitamins, minerals, β-carotene, fatty acids, etc. which makes it best as meals and fodder. NASA has said that the dietary cost of one thousand kg of fruits and veggies equals to at least one kg of Spirulina. In 1992 WHO has declared Spirulina as “Best meals for future” to redress malnutrition specifically in children. Apart from being a meals complement, Spirulina has won sizeable reputation and paramount significance because of the presence of sure pigments and secondary metabolites. It suggests pharmacognosic homes like immuno-protective, anticancer, antidiabetic, antiviral, anti-obesity, etc. it's far the maximum nutritionally concentrated compact entire meals recognized which owe a capacity to significantly lower the probabilities of growing cancer, coronary heart disease, or stroke or of contracting a lifethreatening virus along with HIV and save you eyes from cataract formation. In the present study, spirulina enriched food dhokla (SBDF) was developed. SBDF accept overall acceptability by panelist such as color and appearance, aroma/odour, flavor and taste, body and texture. SBDF showed good amount of protein (10.48%), and iron (30.48%) as compared to control. Afterward, the developed SDFB exhibited good amount of antioxidants content (38.62%) and moisture conent (14.56%), respectively. SBDF can be most attractive and nutritious food for every people due to rich source of protein and iron. This novel food can solve diseases/problems related with protein and iron deficiency.

Abstract:
An experiment was conducted to study characters associated with higher yield potential of potato genotypes at the Directorate of Agricultural Research, Tarahara, Nepal during two consecutive winter seasons of 2018 and 2019. A total of eleven potato genotypes (CIP 394600.52, CIP 396012.266, CIP 393371.159, PRP 266265.15, CIP 395443.103, CIP 393371.164, PRP 336769.1, PRP 136368.9, PRP 25861.11, CIP 377957.5 and PRP 225861.5) were evaluated in a Randomized Complete Block Design with four replications. Each treatment received a 7.2 m2 plot area with 60 cm row to row and 25 cm plant to plant spacing, accommodating 48 plants per plot. Cultural practices were done as per the recommendations and fungicide was not applied for late blight of potato (Phytophthora infestans) control. The observed data were subjected to variance, correlation and cluster analysis. Analysis of variance showed significant differences for some plant and tuber characteristics. From the pooled analysis of two years’ data, the genotype 'PRP 266265.15' was found to be a suitable genotype in plains due to its higher yield (21.91 t/ha) and other yield characteristics. The higher quantity of over seed-size and under seed-size tuber contributed to the highest tuber yield of PRP 266265.15. The weight (r = 0.928**) and number (r = 0.483**) of the over seed-size tuber had a positive significant correlation with tuber yield per hectare. Further research is needed to study yield stability of the genotype 'PRP 266265.15' in various locations with similar production environments.

Abstract:
Bacterial disease is a major biotic constraints of mango production in Côte d'Ivoire. The objective of this study is to assess the distribution of mango bacteriosis disease in mango production areas in northern Côte d'Ivoire. This study focused on 720 mango trees, of the Kent variety, spread over 20 orchards. These orchards are located in the Bagoué, Tchologo and Poro regions in northern Côte d'Ivoire. The study consisted of determining the incidence and severity of bacterial disease on the leaves and fruits of mango trees. Data on the incidence and severity index of bacterial disease on leaves and fruits were subjected to descriptive analysis followed by PCA. Then, the ascending hierarchical classification (CAH) and multivariate analysis completed the data analysis. The results obtained did not reveal any dissimilarity of the presence of the bacterial disease in the three (3) regions studied. On the other hand, a predominance of the severe or major type of bacterial disease over the level of slight or marginal contamination has been demonstrated. None of the three main regions (Poro, Tchologo and Bagoué) of mango production in Côte d'Ivoire appears to be the center of bacterial disease dispersion at the current stage of bacterial disease progression. The level of incidence and severity of this disease is similar between fruits and leaves. The Principal Component Analysis and the Ascending Hierachical Classification completed by the MANOVA made it possible to structure the mango orchards into three (3) homogeneous groups. Group 2 orchards (VB4, VB8, VB7 and VF2) presented a moderate level of incidence and severity on leaves and fruits.

Abstract:
Banana Xanthomonas Wilt (BXW), caused by Xanthomonas campestris pv. musacearum (Xcm), a devastating disease, causes up to 100% loss and affects all banana varieties. The disease is widespread in East and Central Africa region. Study objective was to evaluate the performance of single stem rouging options for rehabilitation of severely affected banana orchard. Five single stem rouging options were implemented in banana orchard with 80% BXW severity in Western Kenya. The options included rouging of infected banana plants; uprooting, cutting at the base, injecting 20 ml of glyphosate herbicide at the soil base of the pseudostem, uprooting the whole stool and control leaving the infected stools. Initial visual assesment before implementation of the orchard was over 80% infection. Later samples were collected for diagnosis of ten plants per treatment from different plant parts and were subjected to ELISA and PCR procedures for confirmion of the presence of Xcm. Rouging options was implemented for one year. During and after experimentation periodic visual assesment of BXW incidence and severity reduced. Results of ELISA assays and PCR results indicated Xanthomonas was present on banana plants. Rouging the infected banana stems by cutting at the base, uprooting and injection of herbicide reduced BXW incidence within six months. Xanthomonas, an inhibiting bacteria cannot surve without host and by killing the banana plant the Xanthomonas dies. Yields were recovered from the rehabilitated orchard within one year. Banana orchard highly infected with BXW was effectively rehabilitated.

Abstract:
In the Central African Republic, there are a multitude of local varieties of sweet potato. However, few studies have been carried their agro morphological and organoleptic characteristics. A Fisher random block device was set up on the three local varieties of sweet potato. The growing and production parameters were evaluated as well as the organoleptic characteristics through the food taste test. The parameters of growing and production were assessed by means of analysis of variance (ANOVA) with one classification criterion using the R software version 3.1.3. A Principal Component Analysis (PCA) was also performed with the growth and yield parameters in order to highlight the correlations between these different parameters. The variety 1 (V1) produced the plants with the largest diameters (1.30 cm), while the smallest diameters was observed in the variety 2 (V2) with 0.55 cm. There is a significant difference (P-value = 0.0001) between the different varieties according to the ANOVA test. According to the length of the tuber, the V2 produced the longest tuberous root than the others with an average of 28.53 cm. The smallest length is observed in the V3 with an average of 25.12 cm. There is not significant (p-value = 0.216) in relation with the length of the tuber for the cultivated varieties of the sweet potato. The eigenvalues of the two main axes extracted from the Principal Component Analysis explained 53.68% and 16.82% of the matrix growth/ yield information. Along the factor axes, apart from parameters such as tuber diameters and length which are not positively correlated, there is little variability between the other parameters which are strongly correlated.

Abstract:
Soil-less system constitutes an efficient approach for the cultivation of tomato; however, organic liquid amendments are very limited under such systems. The current experiment aimed to evaluate the effects of Kurojiru (K), an organic liquid fertilizer and fulvic acid (FA) on the growth and production of tomato, Solanum lycopersicum L. cv. ‘Momotaro’. Recently, it is desirable to reduce the environmental impact and fertilizer cost by lowering the concentration of inorganic components in the culture medium. Therefore, we explored the effect of adding these organic fertilizers on the yield and quality of tomatoes by gradually reducing the phosphoric acid concentration in the culture medium (87, 58 and 29 mmol・pot-1・week-1). The whole experiment was conducted for 20 weeks (from seeding until harvesting). The plant biomass, tomato fruit weight and chlorophyll content were measured. The fresh weight (FW) of both root and shoot indicated a progress response according to phosphorus concentration in liquid media, in FA treatments. Total fresh weight was significantly higher in the treatment with K+FA than in the control. Additionally, the yield responded to the all treatments within the 58 mmol P. Especially, in this level of P the relative fruit weight was higher only under K application. The chlorophyll content responded K+FA treatment under a low P content (29 mmol), and to all of those in 58 mmol. These results indicate that Kurojiru has some positive effects on tomato growth in soil-less systems.

Abstract:
Aims: The primary focus of this empirical study was to investigate the factors influencing the level of GAP adoption for cucurbit vegetable in the Anuradhapura district of Sri Lanka. Study Design: Three-stage purposive and proportionate sampling Place and Duration of Study: The study was carried out in the Anuradhapura district, North Central Province of Sri Lanka in 2018. Methodology: Primary and secondary data were used in the study. The primary data were collected mainly through a field survey using a structured and pre-tested questionnaire. The total sample size was 120. Key informant interviews (KII), and a focus group discussion (FGD) were conducted to triangulate data and information obtained from the questionnaire survey and to obtain additional qualitative information. Descriptive analytical techniques, analysis of variance (ANOVA) test, and the General Linear Model (GLM) were employed for the data analysis. Results: Results revealed that 40% of respondents are moderate level GAP adopters, whilst about 68% practiced more than half of the recommended GAPs. The results of ANOVA revealed that farmers who adopted a higher proportion of GAPs earned a higher farming income, than those who practiced a moderate or low proportion of GAPs. Similarly, when compared to moderate and poor level GAP adopters, the average cost of production of higher-level adopters decreased significantly (p < 0.05). The results of the regression analysis revealed that farmer awareness of GAPs, farmer education level, farming experience, farming income, and cost of cultivation have a significant (p < 0.05) effect on the level of GAP adoption by cucurbit farmers. Conclusion: Awareness of GAPs, farmer education level, farming experience, and farming income significantly affect the adoption level of GAPs. Policy priority should be given to planning for a long-term farmer awareness program on GAPs through proper training and extension programs.

Abstract:
The study assessed the determinants of coffee production and marketing on farmers’ farms in Kogi State. Two Local Government Areas (Ijumu and Kabba-Bunu Local Government Areas) were purposively sampled. These areas are known for the production and marketing of coffee. A total sample of eighty-four respondents was randomly selected from the two Local Government Areas. Structured interview schedules were used for data collection from respondents. The data collected were analyzed using inferential statistics analysis. Cobb-Douglas functional form regression model was chosen based on the value of the R2 and the number of significant variables. The result indicated that marital status, household size, educational level, variety of coffee planted, farm size and farming experience constituted the major factors that significantly determined coffee production and marketing in the study area. The study recommended that policies should be targeted at encouraging literacy among coffee farmers to have access to market information and as such will be able to sell the crop for more profits. Also, households with higher number of persons should be encouraged to use family labour effectively in coffee marketing than other economic ventures so as to improve the economy of the households in the study area.
