Flowering Of Spring-Planted Greens, Elizabeth Maynard, Marian M. Rodriguez-Soto, Rebecca Koetz Mar 2024

Flowering Of Spring-Planted Greens, Elizabeth Maynard, Marian M. Rodriguez-Soto, Rebecca Koetz

Midwest Vegetable Trial Reports

Greens for salad or cooking are a significant part of the spring crop mix sold at Indiana farmers' markets. The harvest period for many spring-planted greens is shortened because they flower in response to environmental conditions. This paper reports on flowering response of two varieties of arugula, collards, mizuna, two types of mustard, and shungiku, planted in mid-April through May in northern Indiana.


High Tunnel Bell Pepper Spacing Trial, Bronwyn Aly Mar 2024

High Tunnel Bell Pepper Spacing Trial, Bronwyn Aly

Midwest Vegetable Trial Reports

The objective of this trial is to determine an optimum spacing for bell peppers grown in a high tunnel production system. Six different spacing treatments were evaluated in this trial. Results from this study suggest that tighter plant spacing increased yield per unit area (100 feet of linear row) but decreased the yield per plant.

Modelling The "Bottom-Up" Development Pattern Of Tar Spot Disease In Corn, Brenden Lane, Joaquín Guillermo Ramírez-Gil, Carlos Góngora-Canul, Mariela Sofia Fernandez Campos, Andres Cruz-Sancan, Fidel E. Jiménez-Beitia, Alex G. Acosta-Guatemal, Wily Sic, C. D. Cruz

Graduate Industrial Research Symposium

In 2015, the corn-infecting pathogen Phyllachora maydis (causal agent of tar spot disease) was reported for the first time in the United States. The disease has since spread across the US, causing major yield losses. In 2021 alone, 5.88 million metric tons (231.3 million bushels) of US corn yield were lost to this disease, costing an estimated US$1.25 billion. Though fungicides can protect against these agroeconomic losses, application timing can be difficult to optimize because our understanding of tar spot dynamics is still evolving. The current view is that tar spot typically develops bottom-up through a repeating infection cycle. Because …


Co-Crystallization Of Urea Granules For Slower Dissolution, Vidya Nagaraju, Carl Wassgren, Kingsly Ambrose Mar 2024

Co-Crystallization Of Urea Granules For Slower Dissolution, Vidya Nagaraju, Carl Wassgren, Kingsly Ambrose

Graduate Industrial Research Symposium

Co-crystals are multicomponent crystals formed through hydrogen bond interactions. Co-crystallization, the process of developing cocrystals, serves as a versatile approach for discovering new solid forms of active ingredients (AIs) that can alter physical properties such as solubility, dissolution rates, and stability. These co-crystals can be produced through three main methods: solid-state methods, solution-based methods, and supercritical fluid methods. Recently, the solid-state (mechanochemical) method of developing cocrystals has gained more attention from researchers in the development of slow-release urea fertilizers. This technique can also be applied to the development of urease inhibitors. These multicomponent crystals present a potential solution to the …

Broccoli is a potentially profitable crop for high tunnel production. Updated information on yield and quality of new cultivars is important for producers making planting decisions. This evaluation of 11 cultivars was conducted within a high tunnel in Fall 2023.


2023 Evaluation Of Pumpkin Cultivars In West Virginia, Lewis Jett Jan 2024

2023 Evaluation Of Pumpkin Cultivars In West Virginia, Lewis Jett

Midwest Vegetable Trial Reports

Pumpkins are a popular, commercial vegetable crop in West Virginia. Each year, many new hybrid cultivars are released by commercial seed companies. In 2023, we trialed 16 cultivars. Pumpkins were grown using conventional tillage, and each cultivar was replicated 4 times. ‘Griffin’ ‘Justify’, ‘Hawk’, ‘Bellatrix’ and ‘Hermes’ produced high yields with both fruit count and average weight per pumpkin.


Biowall Development For The West Lafayette Public Library, Dhanurja De Silva, Yalin Lu, Siqi He, Ajay Dalal, Bill Hutzel Dec 2023

Biowall Development For The West Lafayette Public Library, Dhanurja De Silva, Yalin Lu, Siqi He, Ajay Dalal, Bill Hutzel

Purdue Journal of Service-Learning and International Engagement

A group of multidisciplinary Purdue students are working together to design, assemble, and install a Biowall in the Children’s section of the West Lafayette Public Library. A Biowall is a plant-based filter that improves Indoor Environmental Quality by cleaning indoor air and adding a natural aesthetic to the building space. Purdue has been developing Biowall technology since 2012, and this project involves redesigning it to fit into the available space at the library. The new Biowall design incorporates a watering mechanism that allows for children to get actively involved in maintaining the Biowall and learning about sustainability. This project also …


Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2023, Petrus Langenhoven, Dennis Gustavo Toc Mo Dec 2023

Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2023, Petrus Langenhoven, Dennis Gustavo Toc Mo

Midwest Vegetable Trial Reports

Colored sweet bell-shaped and tapered pepper is a summer crop that is grown by many small and medium-sized farming operations in Indiana. Growers can choose to grow peppers out in the field or plant them under a protective structure. Sweet peppers, in particular, benefit from the unique growing environment created by a high tunnel. Planting of peppers can start at least 2-4 weeks earlier in the spring, and production can continue into the fall until the first hard freeze. Pepper variety performance data for Indiana is not readily available. We are working hard to change that. To date, we have …

Latino fresh market vegetable farmers in Minnesota and Wisconsin are interested in growing hot peppers for local markets, both for fresh and dried pepper sales. This variety trial is the third and final trial of a 3 year project. We trialed 14 varieties of peppers representing jalapeño, serrano, habanero, poblano, and “other” types. The varieties included the top varieties from 2020 and 2021, alongside new varieties. We measured yield, fruit size, and Scoville heat units. In addition to the variety trial, we conducted an enterprise analysis to determine the profitability of hot pepper production in the Upper Midwest.

Butterhead Lettuce Variety Performance Trial In A Hydroponic Nft System, Leah Worth, Mary Rogers, Amanda Reardon Aug 2022

Butterhead Lettuce Variety Performance Trial In A Hydroponic Nft System, Leah Worth, Mary Rogers, Amanda Reardon

Midwest Vegetable Trial Reports

Lettuce (Lactuca sativa L.) is a cool-season crop grown exclusively for fresh consumption. The intensive consumer demand of pre-packaged and living butterheads in the market today has been supported by the shift of soil production methods to soilless hydroponic systems. Hydroponic varietal and fertility recommendations for living butterhead optimization are limited to small-scale growers, however. To increase understanding of butterhead lettuce fertility preference, we examined two different water reservoir fertility concentrations across 12 replicated nutrient film technique (NFT) systems planted with six butterhead lettuce varieties. No differences were found between varieties grown in either recommended or high fertility concentrations, …
