Planting Media and Growth Regulators on Regeneration of Pineapple Seedlings from Crown Leaf Buds | Book Publisher International

Kilifi County has a large potential of over 2,000 Ha suitable for pineapple cultivation that has not been fully exploited due to a lack of adequate clean planting material. The aim of the study was to evaluate the effects of media and the application of plant growth hormones (auxin or gibberellins) on the regeneration of propagules from pineapple crown leaf buds treated with auxins or gibberellin hormones. The study was carried out at Pwani University Crop Science farm from January to December of 2022. Treatments included: planting crown leaves (with buds) treated with auxin or gibberellins hormones (at a spacing of 4 cm by 6 cm) in plastic containers filled with sand, sawdust, coir dust, chitosan, or loamy clay soils. A randomized complete block design with a split-plot arrangement of treatments, replicated thrice, was used. Auxin and gibberellins hormones represented the main-plots. The plastic containers (the sub-plots) used for the experiment measured 30cm by 36cm by 15 cm in height. Data collected from the tagged plants included: time to shoot emergence, plant height, leaf length and breadth, number of leaves per plant, chlorophyll content, final root length, final number of roots, root weight, stem diameter and average root length. These were used to determine the effects of auxin, gibberellins and media on growth of the propagules, on time taken to attain a height of 15-20 cm. Obtained data was subjected to ANOVA using Genstat Statistical software 14th Edition and means obtained were compared using Tukey’s honest significant difference test (p < 0.05). The results showed that there were significant interaction effects between the different media and plant hormones. Chitosan had the highest growth of over 50% in all measured parameters, namely plant height, leaf length and width, stem diameter, root length, root weight and chlorophyll content. Auxin hormone resulted in the highest values of most measured growth parameters compared to gibberellins hormone. The study also showed that auxin-treated propagules had their initial roots originating from the base of the seedlings, while gibberellins treated propagules had their initial roots originating from the base of the cut crown leaves.

Performance of the Pineapple Value Chain in South Western Uganda: Implications for Value Addition | Chapter 6 | Emerging Issues in Agricultural Sciences Vol. 8

 The bomb value chain stands out all at once that should be prioritized for publicity and improvement among the key crop value chains for South Western Uganda on account of its perennial type with depressed pest/disease risk, reduced land requirement, significance for environmental and natural resources’ sustainability, extreme profitability and history of bearing enhanced country household incomes and non- restrictive to entry of country poor. Mean weekly pineapple production peaks were bi-anual and doubled the rainy season. Pineapple food content revealed that fiber was best in pineapples from Isingiro (6.29%) producing a considerably greater amount of pulp (mean: 510.4g/1000g of fresh crop) than Ntungamo (2.03%: mean: 226.15g/1000g of fresh fruit) and Bushenyi (mean: 408.84 g/1000g of new fruit). Soil physico-synthetic parameters varied considerably across the study sites, at 0.05% level of significance. A Pearson’s equivalence test between soil composition and mineral content of pineapples from the various sites disclosed that other than pH, Vitamin C however had a important correlation accompanying soil Nitrogen (p= 0.02), TDS with Magnesium (p=0.01); and fibre with soil natural resources (p= 0.04), Calcium (p= 0.01) and Magnesium (p= 0.02). Pineapples produced in Isingiro had the greatest allotment composition of rude fiber in dry pineapple pulp (mean: 29.6%) trying that dry pineapple pulp is a confidential information for crude fiber for exercise in product incident that focuses on enriching human diet with able to be consumed fiber. The extreme phosphorus and Total Dissolved Solute content (291.7 ppm) of Isingiro pineapples also gives bureaucracy a strong flavor and a very sweetness of taste respectively for processing pineapples into dry sweet crop and snacks. Pineapples from Ntungamo were best suited for liquid squeezed from plant extraction on account of their high moisture content. The new Pineapple value chain in SW Uganda happenings a mean postharvest loss of 19.86% with best loss danger zone being transportation. On average Ntungamo incurred considerably higher postharvest misfortunes (26.9%) than the other two study sites. Solar drying of pineapples for the export was an surely adaptable value adding innovation for limited scale chain actors alongside other potential advantage addition paths such as pineapple sweet drink and juice result for improvement and promotion to embellish pineapple profit chain in South western Uganda.

Study on the Economics of Pineapple Marketing in Anambra State, Nigeria | Chapter 5 | Current Strategies in Economics and Management Vol.6

 

The study analysed the economics of pineapple marketing for entrepreneurial utilization in Anambra
State Nigeria. Data for the study were collected from 104 respondents which comprised of 40 retailers
and 64 wholesalers randomly sampled from eight markets of the study area (4 markets from each of
the two cities). The markets are Main market, Ose, Ochanja and bridge-head market areas were
selected from Onitsha commercial city while Eke, Nkwo Amaenyi, Aroma junction and Nnamdi Azikwe
University(UNIZIK) temporary site market areas were chosen from Awka Capital city. The markets
were purposively selected because they are where higher concentration of middlemen in pineapple
business are commonly found in the cities. Descriptive statistics and gross margin analysis were used
in data analysis. The study inter alia revealed that the majority (62%) of pineapple consumed in the
study area were sourced by the middlemen from outside Anambra State, showing that the state is not
self-sufficient in the crop’s production. Respective return on investment made by the wholesalers and
retailers were (0.23 and 0.32) indicating that the trade on the crop is profitable. It was further revealed
that high transportation cost and lack of fund to increase business scale were the main constraints of
the pineapple traders. The study concluded that investment opportunities exist on the crop’s market,
production and processing and therefore recommends that the potential traders and entrepreneurs
should exploit the crop’s business potentials.
