The Effect Of Two Different Harvesting Methods On The Yield Of 'Topbunch' And 'Hi-Crop' Collards (Brassica Oleracea (L)) When Grown In A Wiregrass Tunnel House, Veronica E. Walton, Raymon Shange, Melissa Johnson, Edward Sparks, Victor Khan, James E. Currington, Ramble Ankumah, Nathaniel Ellison, George X. Hunter Jr., Jeffery L. Moore

Professional Agricultural Workers Journal

A study was conducted to determine if 100% or 50% harvesting of collard leaves was a suitable recommendation for Tunnel House producers. The experiment was conducted as a split-split plot design with varieties as the main plots, harvesting 100% or 50% of leaves as the sub-plots, and days after transplanting as the subplots. All treatments were replicated three times, drip irrigated, and fertilized according to soil test recommendations. The results showed significant interactions between varieties and method of harvest, for leaf numbers and weight. Conversely, the varieties showed significant differences for yield but not leaf numbers. Both varieties showed significant …

The Evaluation Of Two Different Harvesting 'Topbunch' And 'Hi-Crop' Collards (Brassica Oleracea (L)) Leaves From Plants Grown In A Wiregrass Tunnel House, Edward Sparks, Raymon Shange, Jacquelyn Jackson, Victor Khan, James E.

A study was conducted to determine if a 100% or 50% harvest intensity of ‘Topbunch’ collards leaves could be a recommended practice for Tunnel House producers. The experiment was conducted as a split-plot design with harvest dates as main plots, and harvesting intensity of 100% or 50% of leaves as sub-plots. All treatments were replicated three times, drip irrigated, and fertilized according to soil test recommendations. The results showed significant interactions between harvest methods and dates for number and weight of leaves harvested. There were also significant differences for the weight of leaves harvested and numbers. The leaf recovery rates …

Economies Of Scale In Integrated Pest Management In Vegetable And Fruit Production, Franklin Quarcoo, Conrad Bonsi, David Nii O. Tackie, Walter A. Hill, Gertrude Wall, George Hunter

Professional Agricultural Workers Journal

Abstract

Pest management is achieved directly using a variety of tools, including pesticides, and indirectly through a number of agronomic/cultural practices such as irrigation and fertilizer application; collectively these practices function to positively effect general plant health. Healthier plants are more resistant to or tolerant of pests. This study explores the scale differences that impact the pest management significance and suitability of certain agronomic practices. Scale differences were discussed using literature-based information, direct field observations, and anecdotal information on the relative advantages of drip and sprinkler irrigation systems; organic and conventional cultivation of crops; crop rotation versus mono-cropping systems; precision …

Screening Of Olive Cultivars For Tolerance To Fusicladium Oleagineum In South Africa, Zakhele Cyril Msimango

Professional Agricultural Workers Journal

Abstract

This study evaluated commercial olive cultivars for resistance to olive leaf spot (OLS). A growth chamber trial was undertaken with one temperature treatment (16°C) applied during inoculation while a relative humidity (RH) of above 80% was maintained. Plants were kept for 48 hours at 99% RH after inoculation and then moved to shade netted area for disease development at a temperature of 25±5°C. The results were used for categorizing the eight olive cultivars evaluated in this study according to their OLS susceptibility. ‘Frantoio’ was categorized as most tolerant; ‘Nandi’ and ‘Leccino’ were found to be moderately tolerant, and ‘Nocellara …

Extending Sustainable Irrigation Opportunities To Socially And Historically Disadvantaged Farmers In The Alabama Black Belt To Support Commercial-Level Production, Raymon Shange, Richard Martin, Victor Khan, Kwesi Daniels, George X. Hunter, Gwendolyn J. Johnson, Steve Musser, William Puckett, Walter A. Hill

Professional Agricultural Workers Journal

This paper focuses on providing sustainable irrigation opportunities to socially and historically disadvantaged farmers (SHDFs). The ability to provide steady production capacity through the use of renewable energy sources and microirrigation is innovative, in that it demonstrated how to develop and utilize a sustainable irrigation system in both energy and water conservation. This venture is also innovative in that it sought to provide SHDFs with irrigation in a state in which irrigation in agriculture is minimal, while at the same time, offsetting the energy costs that normally accompany irrigation. Several farmers are profiled in their participation in the irrigation program. …

Overview Of The Integrated Pest Management (Ipm) Terrain And Activities In Furtherance Of The Walmart Initiative To Purchase Fresh Vegetables From Local Growers In Alabama, Franklin Quarcoo, Conrad Bonsi

Professional Agricultural Workers Journal

Tuskegee University has been providing various types of technical expertise to limited resource farmers who have been supplying Walmart with collard greens, watermelons and purple hull peas. A number of pests bedevil the cultivation of these crops; cost-effective management methods for these pests are needed. The objectives of this paper are to document the IPM activities associated with supplying produce to Walmart; summarize pest problems encountered on the afore-stated crops; recommend IPM methods suitable for limited resource farmers; and suggest other activities that ensure that farmers incur even less pest-related crop losses. Anthracnose was the major pest encountered on watermelons. …
