Effect of NPK Fertilizers on the Performance of Cassava Varieties (Manihot esculenta Crantz) in Humid Tropics, Niger Delta, Nigeria | Chapter 8 | Current Research Progress in Agricultural Sciences Vol. 10

Primary macronutrients play a very important role in improving the yield and quality of crops. Three main elements are nitrogen, phosphorus, and potassium (N, P, and K) and are required in abundance. They must be readily available through soil medium or fertilizer. An experiment was conducted to determine the performance of three cassava varieties with two NPK fertilizer types. The study was done at the Rivers State University Teaching and Research Farm in Port Harcourt, between March 2021 and February 2022. The treatments were cassava varieties TMS 95/0289, TMS 96/0523, and TME 419. NPK fertilizers were NPK 15-15-15 and NPK 20-10-10. The treatments were combined in a split-plot arrangement in a Randomized Complete Block Design (RCBD) replicated three times. Parameters evaluated were the number of branches per stand and canopy width which were assessed from 10 weeks after planting and subsequently at 4 weekly intervals. Fresh/dry pulp weight and fresh/dry peel weight were determined after crop harvest.  The evaluation of the performance of three cassava varieties was studied using two compound fertilizer types at the Teaching and Research Farm, Rivers State University Port Harcourt between March 2021 and February 2022. The treatments were combined in a split-plot arrangement in a Randomized Complete Block Design (RCBD) with three replicates. Parameters evaluated were the number of branches and canopy diameter at four weekly intervals starting from the tenth week after planting and ending with fresh/dry pulp weight and fresh/dry peel weight were also taken. Results show that cassava variety TMS 95/0289 interacting with NPK 15-15-15 produced the highest branches per plot (24.7), TMS 96/0523 interacting with NPK 15-15-15 produced the widest canopy diameter per stand (263.1cm), fresh peels weight and dry peels weight (129.7g and 100.3g). TME 419 interacting with NPK 15-15-15 compound fertilizer produced the highest fresh and dry pulp weight with mean values of 722.7 and 487.0. Application of NPK fertilizer especially NPK 15-15-15 enhanced the number of branches, dry pulp weight, dry peel weight and canopy diameter. TME 419 had higher fresh/dry pulps and dry peels weight while TMS 96/0523 had high fresh peels weight and canopy width respectively. Whereas cassava variety TMS 95/0289 was high in the number of branches. Thus it is recommended that TME 419 be introduced to farmers as it produces the highest pulp weight per stand. Also, fertilizer NPK 15-15-15 is a preferred NPK fertilizer as it has the capability to increase the number of branches, canopy width, peel weight and pulp weight in comparison with NPK 20-10-10. Further growth and yield were mostly enhanced with NPK 15-15-15 fertilizer application compared to NPK 20-10-10. However, more field research on these fertilizers is needed to better understand their effects on cassava performance.

Effect of Different NPK Doses for Growth Response of Cassava Varieties in Rivers State, Nigeria | Chapter 6 | Research Advances and Challenges in Agricultural Sciences Vol. 7

The present study was designed to evaluate the effect of two NPK fertilizers on the growth response of three cassava varieties. The most of cassava varieties can tolerate marginal soils thereby playing a vital role in food security in Africa as a major staple food. Nigerian farmers in cassava-growing regions plant it as either a main or supplementary crop, and use bush fallowing and crop rotation to keep the soil healthy. Study on the growth response of three cassava varieties (TME 419, TMS 95/0289, TMS 96/0523) using two levels NPK fertilizers (NPK 20-10-10, NPK 15-15-15kg/ha) was carried out at the Rivers State University Teaching and Research Farm, Port Harcourt, Nigeria. The study was designed using Randomized Complete Block Design and replicated thrice. Parameters measured were number of stands, number of stems, stem weight, fresh leaves weight, dry leaves weight and stalk weight. Result showed that cassava variety TMS 96/0523 interacting with NPK fertilizer level 15-15- 15 kg/ha produced the highest number of stems while TME 419 interacting with NPK 20-10-10 produced the least number of stems at harvest. Cassava variety TMS 95/0289 interacting with NPK 15-15-15 produced the highest stem weight (57.3) and stalk weight (27.0) while TME 419 interacting with NPK 15-15-15 had the highest mean value in fresh/dry leaves weight respectively. The monocropping of cassava leads to rapid depletion of major plant nutrients especially N and K and will require fertilizer supplement to give economic yield.  In varietal differences, TME 419 was higher (P<0.05) in number of stands and fresh/dry leaves weight, TMS 95/0289 produced the heaviest stalk weight and stem weight while TMS 96/0523 was higher in number of stems. NPK 15-15-15 was highest in number of stems, stem weight, number of stands, fresh/dry weight and NPK 20-10-10 was high in stalk weight. Thus, NPK 15-15-15 fertilizer is highly recommendable as it improved stem number, stem weight, fresh leaves weight and dry leaves weight of the studied varieties.

Effects of Two Compound Fertilizer Types on the Growth and Yield Performance of Three Cassava Varieties (Manihot esculenta Crantz) in Humid Tropics Niger Delta, Nigeria | Chapter 2 | Emerging Issues in Agricultural Sciences Vol. 7

 The study aims were; (a) assess the extreme yielding assortment amongst the three cassava assortments (TMS 95/0289, TMS 96/0523 and TME 419). (b). evaluate the impact of the compound fertilizers (N-P-K- 20:10-10and N-P-K 15—15-15) on the development performance of the three cassava types in terms of tumor and yield. (c) determine the effect of interplay between the N.P.K. fertilizers and the three cassava verities. Cassava (Manihot esculenta Crantz) is a enduring crop of the family Euphorbiaceae tame in Nigeria. It is a root crop namely propagated vegetatively from stem cutting for commercial purposes, but can more be propagated by source. Cassava is however, not customarily planted singular under the traditional cutting system so concerning maximize the farmer’s revenue generation and again to produce diverse crops on the restricted available land field. Thus, an experiment on the growth and yield reactions of cassava (Manihot esculenta Crantz) using two compound manure types was conducted at the Teaching and Research Farm, Rivers State University Port Harcourt betwixt March 2021 and February 2022. Three cassava varieties (TME 419, TMS 95/0289, and TMS 96/0523), two types of compound manure (NPK 20-10-10 and NPK 15-15-15), and a control with no manure request were combined in the situations. The treatments were start as a split plot with the cassava differences going in the main plot and the manure types going in the subplots, in a Randomized Complete Block Design (RCBD) replicated three opportunities. Parameters evaluated were plant climax and leaf number at four weekly break starting at ten weeks following in position or time planting, too tuber number and vegetable weight. Results show that cassava difference TME 419 interacting accompanying NPK 15-1515 produced the best plant height (288.3cm) while TMS96/0523 outside fertilizer use produced rude plant height(199cm) at harvest.  Significantly more leaves, tubers, and plant crest were created using NPK 15-15-15. Comparing the fertilized plots to the unfertilized plot (control), the fertilized plots caused considerably more new tubers and heavier tubers. Since the sort and compound fertilizer produce the maximum tuber number and vegetable weight, TMS 95/0289 and NPK 15-15-15 endure be suggested to ration farmers in consideration of boost cassava output.

Response of Chickpea Varieties to Different Sowing Dates at Toke Kutaye District, Ethiopia | Chapter 10 | Emerging Issues in Agricultural Sciences Vol. 3

 Native bacterial microflora from traditional dumping yards will improve the agriculture solid waste administration and under stress surroundings particular bacterial consortia will produce a variety of enzymes in the way that protease, lipase, and amylase. The majority of agricultural waste is containing residues like cellulose, lignin, chitin, keratin, and jam, which can only be shabby by naturally occurring microorganisms, fungi, protozoa, and actinomycetes that are worthy doing the task. In addition, microbes are important in the disruption of various land wastes. Agriculture wastes are swiftly controlled by efficient native bacteria that produce eco-friendly, inexpensive dynamic substrates from the field itself and build compost beds above ground level to prevent referring to practices or policies that do not negatively affect the environment damage. At intervals of four days, consortium native bacterial civilizations are added to the beds while the hotness and moisture are held neverending. After 28 days, the material breakdown converts into fertilizer, and this final microbial fertilizer is added to the vermicomposting process to produce vermicompost. The custom of bacteria can have favorable unending environmental belongings on the ecosystem.

A Study of the Weather Variability Influence on Occurrence and Damages of Mononychellus tanajoa Bonder (Acarina: Tetranychidae) on Selected Cassava Varieties in the Lake Zone, Tanzania | Chapter 9 | Cutting-edge Research in Agricultural Sciences Vol. 13

During the dry seasons of 2015 and 2016, a study was undertaken in Tanzania's Lake Zone, which is the country's main cassava producer. Its goal was to determine the impact of weather variables on the incidence of Cassava green mites (CGM), Mononychellus tanajoa, on regularly produced cassava types and the damages they inflict. Cassava is a staple food for 200 million Africans living in poverty, as well as a significant source of employment and revenue, particularly for small and medium-sized businesses. The studies were set up in a Split plot design, with subplots representing varieties and main plots representing localities. Ukiruguru, Ng'ombe, and Kishiri were the three places, with the first two in Misungwi and the third in Kwimba districts. The natural occurrence of M. tanajoa infestation was allowed. In both years, the population of mites and the amount of damage caused by them differed significantly (P0.05) among cultivars, data collecting dates, and locations. In general, the highest population of M. tanajoa was found in Kwimba in 2015 and Ukiruguru in 2016, while the lowest was found in N'gombe in both years. Both seasons, Ukiriguru had the highest root yield. The most susceptible kinds in both years were Liongo Kwimba and Naliendele, whereas Suma and Kyaka were reported to have tolerated/resisted the pest. In all seasons, rainfall, relative humidity, and temperature all played a role in M. tanajoa's survival, propagation, and harm.
