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, …

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.
