Assessing the Impacts of Inorganic and Organic Fertilizer on Crop Performance Under a Microirrigation-Plastic Mulch Regime

This study was conducted at S & B Farm located in Eufaula, AL in 2014. The treatments were Inorganic fertilizer/“Farmer’s Mix” (NPK 13:13:13 + ammonium nitrate mixed in 3:1 ratio); Inorganic fertilizer/“Farmer’s Mix” (NPK 13:13:13 + ammonium nitrate mixed in 3:1 ratio + Bio-grow) plus microbe mix; and Organic Fertilizer – Mighty Grow (4-3-4) with a microbe mix. All fertilizers were applied prior to mulch application after which the following crops squash (Cucurbita pepo L.), cucumber (Cucumis sativus L.), and okra (Abelmoschus esculentus L. Moench) were directly seeded in a complete randomized design. The results showed that the inorganic fertilizer had higher yields (lbs/acre) than organic fertilizer. The addition of microbes to the inorganic fertilizer significantly increased the numbers of cucumbers and okra per acre. Overall, the “Farmer mix” with or without the addition of microbes significantly increased yields for all crops compared to the organic-based fertilizer.
