Impact of Temperature on Performance of Vermicompost Amended Transplant Media for Growth of Vegetable Seedlings
ثبت نشده
چکیده
Successful transplant production begins with selecting good growing media. Healthy vigorous transplants will be less susceptible to insects, diseases and transplant shock, leading to improved overall crop performance. Formulating organic potting mixes is especially challenging. Organic sources of nitrogen, such as compost, can be inconsistent. Compost chemical, biological and physical characteristics can change over time with storage; as a result, nitrogen (N) mineralization and availability to plants can be unpredictable. An alternative to traditional thermophillic compost is vermicompost. Vermicompost has more soluble nitrogen than thermophillic compost. Past research in the Rangarajan lab has shown improved transplant growth and crop yields with vermicompost compared to thermophillic compost.

Application of green walls still has not attracted interest among the contractors and people, and this can be due to poor growing performance of the plants on these systems. This study investigated the effect of four growing media types (30% cocopeat + 65% perlite + 5% vermicompost, 30% soil + 65% perlite + 5% vermicompost, 30% mushroom compost + 65% perlite + 5% vermicompost and regular soil a...
