Nutritional Evaluation Of Banana Peelings From The Various Banana Varieties In Different Regions Of Uganda, J. Nambi-Kasozi, Elly N. Sabiiti, F. B. Bareeba, E. Sporndly Jun 2023

Nutritional Evaluation Of Banana Peelings From The Various Banana Varieties In Different Regions Of Uganda, J. Nambi-Kasozi, Elly N. Sabiiti, F. B. Bareeba, E. Sporndly

IGC Proceedings (1997-2023)

In Uganda, peri-urban agriculture is very important in sustaining livelihoods of the increasing population in urban and peri-urban (U & PU) areas. However, this form of agriculture has a number of problems, feed shortage being the most important. The agricultural produce brought in from the rural areas is marketed in raw form hence increasing the crop wastes in the market areas. The crop wastes, if properly sorted, can serve as alternative feeds for the animals kept in the U & PU areas. Banana (Musa spp) peelings (BP) constitute the largest proportion of all the crop wastes in most …


Perennial Ryegrass Variety Differences In Nutritive Value Characteristics, T. J. Gilliland, R. E. Agnew, A. M. Fearon, F. E. A. Wilson May 2023

Perennial Ryegrass Variety Differences In Nutritive Value Characteristics, T. J. Gilliland, R. E. Agnew, A. M. Fearon, F. E. A. Wilson

IGC Proceedings (1997-2023)

Animal grazing performance at grass is predominately determined by herbage intake rates, with high yielding dairy cows requiring up to 20 kg/d DM within a limited grazing time (Gibb, 1998). Grass nutritional factors such as seasonal patterns in digestibility and water-soluble carbohydrate levels have been linked to animal productivity (Davies et al., 1991), while sward surface height, herbage mass, bulk density and green leaf mass have been shown to promote high grazing intake (Barrett et al., 2001). Furthermore, fatty acid profiles have been shown to improve the unsaturated fatty acid composition of milk, with potential human health benefits …

Intake Characteristics Of Diploid And Tetraploid Perennial Ryegrass Varieties When Grazed By Simmental X Holstein Yearling Heifers Under Rotational Stocking Management, R. J. Orr, J. E. Cook, K. L. Young, R. A. Champion, A. J. Rook Feb 2023

Intake Characteristics Of Diploid And Tetraploid Perennial Ryegrass Varieties When Grazed By Simmental X Holstein Yearling Heifers Under Rotational Stocking Management, R. J. Orr, J. E. Cook, K. L. Young, R. A. Champion, A. J. Rook

IGC Proceedings (1997-2023)

Orr et al. (2003) measured large differences in dry matter (DM) intake rate between 15 intermediate-heading perennial ryegrass varieties when they were continuously stocked with sheep and subsequently explored the extent to which, for 5 of these varieties, these differences could be explained by chemical and morphological traits (Orr et al., 2004a) which could be targeted in grass breeding programmes. Here, four of the 15 varieties, which within ploidy had low or high intake characteristics when grazed by sheep, were rotationally stocked with cattle and intake and sward factors were measured.


Tillering Potential And Stability Of Winter Wheat Varieties Commonly Grown In Kansas, L. O. Pradella, R. P. Lollato Jan 2023

Tillering Potential And Stability Of Winter Wheat Varieties Commonly Grown In Kansas, L. O. Pradella, R. P. Lollato

Kansas Agricultural Experiment Station Research Reports

The tillering potential and stability of winter wheat (Triticum aestivumL.) can be positive traits by conferring adaptation to distinct production environments. The literature demonstrates a high correlation between the tillering potential and many yield components. However, the actual impact of tillering potential on grain yield is not clear. Our goal was to quantify the tillering potential and stability of a range of winter wheat varieties. Field experiments were conducted in six locations in the state of Kansas during the 2021–2022 season. A complete factorial treatment structure of twenty-five winter wheat varieties by two seeding rates (400,000 seeds per …


2021 Kansas State University Industrial Hemp Dual-Purpose Variety And Planting Date Trials, Kraig Roozeboom, Jason Griffin, Andrew Euler, Ike Bahr, Brian Owuoche Jan 2023

2021 Kansas State University Industrial Hemp Dual-Purpose Variety And Planting Date Trials, Kraig Roozeboom, Jason Griffin, Andrew Euler, Ike Bahr, Brian Owuoche

Kansas Agricultural Experiment Station Research Reports

Hemp is a broad term used to describe the many varieties ofCannabis sativaL. that produce less than 0.3% tetrahydrocannabinol (THC). The crop is globally significant, but only recently was allowed to be grown again in the United States. There are many uses for industrial hemp, and the market for industrial hemp is rapidly growing as more states are legalizing its production. The market for industrial hemp exceeded $205 million in 2020 and could surpass $310 million by 2028 (Global Market Insights Inc., 2020). The main components of the industrial hemp market are oil, seeds, and fiber. Varieties have …


2022 Kansas State University Industrial Hemp Dual-Purpose Variety Trials, Kraig Roozeboom, Jason Griffin Jan 2023

2022 Kansas State University Industrial Hemp Dual-Purpose Variety Trials, Kraig Roozeboom, Jason Griffin

Kansas Agricultural Experiment Station Research Reports

Hemp is a broad term used to describe the many varieties ofCannabis sativaL. that produce less than 0.3% tetrahydrocannabinol (THC). The crop is globally significant and has recently been approved in the United States. There are many uses for industrial hemp, and the market for industrial hemp is rapidly growing as more states are legalizing its production. Industrial hemp is marketed for oil, grain, and fiber. Varieties have been selected for improved fiber and grain production that can service these markets. However, little research-based information is available regarding adaptability or production of these varieties in Kansas. The objectives …


Does Winter Wheat Yield Response To Fungicide Application Depend On Nitrogen Management?, J. A. Romero Soler, L. O. Pradella, N. Giordano, G. Cruppe, R. P. Lollato Jan 2023

Does Winter Wheat Yield Response To Fungicide Application Depend On Nitrogen Management?, J. A. Romero Soler, L. O. Pradella, N. Giordano, G. Cruppe, R. P. Lollato

Kansas Agricultural Experiment Station Research Reports

Nitrogen and fungicide are among the more important management tools to increase wheat (Triticum aestivumL.) grain yield in Kansas. However, there is limited information on whether hard red winter wheat grain yield is impacted by the interaction of nitrogen rates and foliar fungicide application. Thus, our objective was to evaluate the effects of different N rates with or without a fungicide application at Feekes 10.5 on grain yield of two winter wheat genotypes with contrasting disease resistances to leaf and stripe rust. Eleven field experiments were established across Kansas using a factorial structure of two fungicide management options …


Chloride Fertilization’S Impacts On Kansas Winter Wheat Grain Yield During 2021-2022, Luiz O. Pradella, Jorge R. Soler, Romulo P. Lollato Jan 2023

Chloride Fertilization’S Impacts On Kansas Winter Wheat Grain Yield During 2021-2022, Luiz O. Pradella, Jorge R. Soler, Romulo P. Lollato

Kansas Agricultural Experiment Station Research Reports

Previous work suggests that wheat can respond to chloride fertility in Kansas and other regions, but this response depends on Cl availability and the wheat variety. In this study, we aimed to identify and quantify the effects of chloride fertilizer application in different areas and winter wheat varieties across Kansas. Sixteen field experiments were conducted during the 2021–2022 growing season. All experiments were conducted in a split-plot design with Cl fertility levels as whole plot (0 or 20 lb Cl/a) and wheat variety as subplots, with either three or four replicates. One protocol evaluated 24 winter wheat varieties in three …
