Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2022, Petrus Langenhoven, Lian Mahorith Duron Alvarado, Eduardo Jose Miranda Oviedo

Midwest Vegetable Trial Reports

Colored sweet bell-shaped and tapered peppers are a staple at the farmers' market. Many small and medium-sized farming operations in Indiana grow this summer crop. High tunnels allow growers to protect their crops and extend their growing season. Sweet peppers, in particular, benefit from the unique growing environment created by the 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. Currently, we have evaluated twenty-five …

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, …

Chile Pepper Variety Evaluation, Charlie Rohwer, Natalie Hoidal

Midwest Vegetable Trial Reports

Producing chile peppers for fresh and dried markets has garnered special interest from Latino growers in Minnesota, and remains of interest to all growers. To increase understanding of market potential, we performed a single-location replicated variety trial. We measured yield, fruit size, and Scoville heat units on harvested fruit from 10 chile varieties representing jalapeños, serranos, poblanos, and habaneros. Yield was similar across chile types (3–4.9 pounds per plant), except 'Ancho Poblano' and 'Habanero Orange' only averaged 1.2–1.8 pounds. 'Habanero Orange' had the highest scoville, followed by jalapeño, serrano, and poblano. There were notable differences in fruit size within each …

Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2021, Petrus Langenhoven Jan 2022

Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2021, Petrus Langenhoven

Midwest Vegetable Trial Reports

Pepper production in high tunnels during the summer is very popular. The high tunnels lower the incidence of foliar disease, protect the crop against severe weather conditions and it extends the production season into the fall. Production of summer crops is generally high in an unheated high tunnel. However, information is lacking about varieties that are adapted for high tunnel production in Indiana. In this paper, we report on five sweet bell and five tapered pepper entries that were evaluated at the Purdue Student Farm, West Lafayette, Indiana.


Impacts Of Nitrogen Rate And Source Following Green Manure On Broccoli Yield, Charlie Rohwer Jan 2022

Impacts Of Nitrogen Rate And Source Following Green Manure On Broccoli Yield, Charlie Rohwer

Midwest Vegetable Trial Reports

Cover crops are beneficial to soil structure and processes and can provide nitrogen (N) to a subsequent crop. Practical studies of N availability from cover crops and organic fertilizers in naive (transitioning) soils are helpful for growers to achieve desirable yield. Microbial soil inoculants (biostimulants) may enhance availability of organic N sources. We found a spring-planted pea-oat cover crop provided less than 27 pounds of N to a subsequent broccoli crop, and no impact of a commercial biostimulant on broccoli yield or development rate. Availability of N from organic amendments used is discussed.
