In a recent visit to a high tunnel, we observed a severe salinity problem on tomatoes. Approximately one month after planting , most tomato plants in the affected area had not sent out any new leaves. Roots did not grow at all (Figure 1). After conducting a soil test, very high soluble salt level explains[Read More…]
Soil temperatures are critical for seed germination and are closely related to occurrences of some early season soilborne disease and pest problems on vegetable crops. Plant vegetable crops after the soil is warm enough ensure good seed germination and fast crop establishment. The figures below show daily average soil and air temperatures at recorded at[Read More…]

In a previous article ‘Opportunities in Hydroponics’ (VCH 609) we discussed two types of Hydroponics, solution culture and medium culture. In this article we will focus on Growth Substrates (media), which form an integral part of medium culture. Growth substrates can be divided into two groups, organic and inorganic media. Inorganic media can be further[Read More…]
In recent years, protecting declining populations of pollinators has become an important issue. Many of our vegetable crops are dependent upon pollinators for production of fruit. Below is a table that highlights the benefits of honey bees and other pollinators for vegetable production. Crops That Require Pollinators Crops That Don’t Require Pollinators But Have[Read More…]

We went through an unseasonably cold period in early April (Figure 1). In southern Indiana, a few high tunnel tomato growers have already planted their crops. These plants may need some extra help. In Vincennes, IN, we used row covers to cover the newly planted tomatoes in high tunnels the past few nights, our recorded lowest temperature[Read More…]
Census data showed that in 2014 Indiana (12 acres), Illinois (11 acres) and Kentucky (13 acres) dedicated a very small portion of their food crop acreage to production under protection. According to the USDA National Agriculture Statistical Service 2014 Horticulture Specialties Census, of all the states surrounding Indiana, Ohio and Michigan have grown and sold[Read More…]
