Evaluation of the Resistance of Five Tomato Varieties to Bacterial Wilt (Ralstonia solanacearum) under the Agro-climatic Conditions of Katibougou | Chapter 8 | Microbiology and Biotechnology Research: An Overview Vol. 4

 

The objective of this research is to contribute to the improvement of tomato productivity in Mali. Tomatoes remain one of the most widely grown vegetable crops in the world. It is the most consumed vegetable in the world after potatoes. However, its production faces enormous difficulties such as the extreme poverty of the soil, the low technicality of the producers, the high pest pressure and the scarcity of high-performance varieties. Of these, bacterial wilt is an important factor, as it causes a huge loss of production on average if left unchecked. A study was carried out on the evaluation of the resistance of five varieties of tomato (Anaya, Raja, Tingal, Mona and Petomek) to bacterial wilt (Ralstonia solanacearum) in the agro-climatic conditions of Katibougou. The experimental device used was the Fisher block with three (03) repetitions to five (05) treatments. The analysis of biometric observations shows that the Raja variety had the largest diameter at the collar with 12.13 cm at the 60th day after transplanting, the highest number of leaves at 40.1, it also gave the highest number of branches with 9.8 and also the greatest height of the plants with 82.5 cm. Regarding the incidence of bacterial wilt, the Petomek variety (T5) had the highest percentage with 73%, followed by the Anaya variety (T1) which had 70%. As for the severity, a total of three (03) observations were made, the analysis of variance showed a significant difference between the levels of variation, the Petomek variety (T5) had the highest score with 85.9%, followed by the Anaya variety (T1) which recorded 84.4% and finally the Tingal (T3) and Mona (T4) varieties had the lowest scores 24.4%. In terms of yield, the Tingal variety had the best yield with 45.83 t/ha, followed by the Mona variety with 39.46 t/ha. Finally, the Anaya and Petomek treatments gave the lowest yields with 21.66 t/ha and 20.55 t/ha, respectively.

Assessment of Grain Weight of Maize to Variety, Organic Manure and Inorganic Fertilizer of Asaba Area of Delta State | Chapter 7 | Cutting-edge Research in Agricultural Sciences Vol. 12

 The Teaching and Research Farm at Delta State University's Asaba Campus was used to analyse the response of maize grain weight to variety, organic manure, and inorganic fertiliser from March 2008 to June 2010. Using a Randomized Complete Block Design, the experiment was repeated three times in a factional pattern (RCBD). Three distinct maize varieties were seeded at 75cm x 15cm and grain weight was measured using four different amounts of poultry manure, cow dung, and NPK 20:10:10 fertiliser. The hybrid variety that produced 2.1 tha-1 yield in 2008 and 2.3 tha-1 yield in 2009 was found to be superior. The findings of interaction in 2008 and 2009 demonstrated that variety, manure type, and application rates were all significantly different (p0.05). According to the findings of the study, I 9022-13, a hybrid maize variety with excellent grain weight, should be grown in the research region. Farmers who want open-pollinated varieties for maize production should grow BR9922-DMRSF2 or the Agbor local variety. (iiFor enhanced maize crop weight, farmers who prefer mineral fertilisers should apply 450 kg NPK 20:10:10 per hectare. (iii) Farmers who practise organic agriculture in the Asaba agro-ecological zone should use 30tha-1 poultry manure to increase maize yields.

The Influence of Agro-Ecological Factors on Fruit Mineral Content and Occurrence of Jelly Seed Disorder in ‘Tommy Atkins’ and ‘Van Dyke’ Mangoes in Kenya | Chapter 13 | Cutting-edge Research in Agricultural Sciences Vol. 8

 One of the most serious issues in mango production in Kenya, as well as other mango-producing countries around the world, is jelly seed disorder. Jelly seed is a physiological condition that expresses itself in the breakdown of tissues around the seed, reducing the marketability of the affected fruits. This problem presents itself in the affected fruits' tissues around the seed, resulting in unmarketable fruits. Although the exact cause of mango jelly seed is unclear, some sources suggest that the condition is caused by an imbalance in the supply of Ca, Mg, N, and K to the fruit. In order to determine the scope of the problem in Kenya, a study was conducted in 2013 in three major mango-producing counties, Embu, Murang'a, and Meru, which are located in separate agro-ecological zones. Per county, three farms with homogeneous trees of “Tommy Atkins” and “Van Dyke” mangoes were chosen at random. To assess the nutrient status, soil and mango leaf analysis were performed. During the study period, data on rainfall and temperature were also collected. At harvest time, 50 tree-ripe fruits of each variety were randomly selected from 25 trees per site and sliced along the endocarp to reveal the seed, which was then visually inspected and graded using the Galan Sauco scale for the incidence of jelly seed. Meru vertisol and lithosol soils had higher Ca, Mg, and K content than Murang'a eutric Nitisol soils and Embu ferralic arenosal soils, according to soil research. Similarly, mango leaves and fruits from Meru county contained more calcium, magnesium, and potassium than those from Murang'a and Embu counties. Fruits from Embu county (both varieties) had more jelly seed than those from Murang'a and Meru counties. In comparison to ‘Tommy Atkins' mangoes, ‘Van Dyke' mangoes had significantly more jelly seed events. As a result, incidences of jelly seed are dependent on the variety as well as the agro-ecological zone where the mangoes are grown.

Effect of Conservation Methods on the Mineral Contents and the Nutritional Quality of the Oil of Some Maize Varieties (Zea mays L.) Produced in Côte d’Ivoire | Chapter 10 | Current Research Trends in Biological Science Vol. 3

Objective: The aim of this study was to evaluate the effect of conservation methods on the mineral
content of some maize varieties during post-harvest storage. To meet the needs for the human and
animal consumption, it is necessary to determine the mineral contents of raw materials.
Methodology: Eight maize varieties, including two local varieties used as controls (“Violet de Katiola”
and AC176) and six improved varieties (Obatanpa, MDJ, EV8728, GMRP18, Acr97TZLcomp-1w and
Acr97TZLcomp-1wsynth), produced by the Centre National de Recherché Agronomique (CNRA),
were stored according to three preservation methods (granary, attic and jute bag) during 120 days.
Sampling was performed every 30 days, followed by chemical analyses.
Results: The ash contents of local varieties were better preserved in the granary than in the attic or
the jute bag because no significant variation was observed at the end of the preservation time. In
improved varieties, all the ash contents varied. Concerning constitutive minerals, magnesium and
calcium contents were preserved in all varieties respectively during 30 and 120 days of storage in the
granary, the attic and the jute bag. On the other hand, some variations were observed for potassium
and phosphorus contents. For example, “Violet de Katiola” potassium content was best preserved in
the jute bag during 120 days; AC176 and EV8728 potassium contents were best preserved in the attic
respectively during 90 days and 60 days. The three preservation modes were suitable to maintain
ACr97 comp1wsynth potassium content between 60 and 120 days; but in this variety, phosphorus
was best preserved in the attic during 90 days. In level of nutritional quality of oil of the maize
varieties, the tenor of palmitic and linoleic acids of local varieties remained stable for 2 months in the
bag and 4 months in the attic, respectively, whereas the levels of oleic and linolenic acids remained
stable for 4 months in the canary. For improved varieties, palmitic and linoleic acid levels remained
stable for 2 months and 4 months respectively in the bag and oleic acid levels for 4 months in the attic
and canary. For For improved varieties, palmitic and linoleic acid levels remained stable for 2 months
and 4 months respectively in the bag and oleic acid levels for 4 months in the attic and canary.
Ultimately, the impact of duration and the method of conservation on the parameters of the corn grain
oils studied depends on the variety.
Conclusion: The three modes of maize grain storage were suitable to preserve magnesium and
calcium contents of local and improved varieties and Acr97TZLcomp1-wsynth potassium content.
Also, the impact of duration and the method of conservation on the parameters of the corn grain oils
studied depends on the variety
