Tropical Crop

The information of tropical crop production environment includes the wind velocity and direction data, light intensity, air humidity, air temperatures, soil moisture, concentration of carbon dioxide, rainfall and so on. These data will be of great reference value to environmental control and scientific field management. As the characteristics of tropical crop growth and tropical climate conditions, information acquisition and tracking about the environment of crop growth are quite behind the time. This research is precisely centers on this core question to launch, carrying on analysis on the key technology of intelligent sensor and monitoring about tropical crop production environment. We build a system on a tiny210 chip using android operating system. Sensors that will be linked include air humidity & temperature sensor, illumination sensor, soil moisture sensor, wind-direction sensor and wind power sensor. This research focuses on field information dynamic acquisition and management. This study can offer references for in field environmental control and further research work.

Large Scale Cultivation

Polynesians introduced the tropical crop taro (Colocasia esculenta) to temperate New Zealand after 1280 CE, but evidence for its cultivation is limited. This contrasts with the abundant evidence for big game hunting, raising longstanding questions of the initial economic and ecological importance of crop production. Here we compare fossil data from wetland sedimentary deposits indicative of taro and leaf vegetable (includingSonchusandRorippaspp.) cultivation from Ahuahu, a northern New Zealand offshore island, with Raivavae and Rapa, both subtropical islands in French Polynesia. Preservation of taro pollen on all islands between 1300 CE and 1550 CE indicates perennial cultivation over multiple growing seasons, as plants rarely flower when frequently harvested. The pollen cooccurs with previously undetected fossil remains of extinct trees, as well as many weeds and commensal invertebrates common to tropical Polynesian gardens. Sedimentary charcoal and charred plant remains show that fire use rapidly reduced forest cover, particularly on Ahuahu. Fires were less frequent by 1500 CE on all islands as forest cover diminished, and short-lived plants increased, indicating higher-intensity production. The northern offshore islands of New Zealand were likely preferred sites for early gardens where taro production was briefly attempted, before being supplanted by sweet potato (Ipomoea batatas), a more temperate climate-adapted crop, which was later established in large-scale cultivation systems on the mainland after 1500 CE.

General Overview

Asian vegetable crops are rapidly expanding in Florida in the last decade due to their health benefits combined with their high profitability. These crops can help increase vegetable growers’ income and diversify Florida’s crop production, and they are new to most Floridians. This new 5-page article provides a general overview of bok choy for vegetable growers, crop consultants, certified crop advisors, Extension agents, and graduate students. Written by Hai Liu and Guodong Liu and published by the UF/IFAS Horticultural Sciences Department.https://edis.ifas.ufl.edu/hs1337
