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