The obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), is a serious pest of apples and other tree crops throughout North America. A review of temperature dependent development and models show that five different lower thresholds for development are published and used as the basis of heat-driven phenology models. We present a small lab data set of C. rosaceana...
Aquaponics, a combination of fish farming and soilless plant farming, is growing in popularity and gaining attention as an important and potentially more sustainable method of food production. The aim of this study was to document and analyze the production methods, experiences, motivations, and demographics of aquaponics practitioners in the United States (US) and internationally. The survey w...
During the recenit period ineluding the years of 1925 to 1940 there have been seven years in which the crops from onion seed suffered a serious leaf injury resulting in low yields. The disease is apparently physiological, for there has not been a single instance in either past or recent investigations that showed the presence of a pathogen when the plants exhibited the first signs of injury. Th...
A Study on the Survey and Documentation of Underutilized Crops of Three Districts of Nagaland, India
Survey was made in three different districts of Nagaland, India (Mokokchung, Wokha and Zunheboto) by interacting with the people about the plants/parts used by them. Information was also collected on the purpose of use, source of the plants/parts, season of collection, preparation process. Some of the selected plant species were collected from the wild and established in the Departmental experi...
The present study was carried out in the rice-wheat area of Pakistani Punjab. The data for the study was collected from three main districts of central Punjab Province i.e. Gujranwala, Sheikhupura and Hafizabad. In total 234 farmers were interviewed. The impact of agricultural extension services was estimated on adoption of new improved technologies and crop yields. The propensity score matchin...
The timely and efficient commercialization of innovation is one of industry’s principal needs if it is to invest in research and development within a given jurisdiction. Increasing regulatory requirements are resulting in longer regulatory approval times, and in some cases where socio-economic considerations are now part of the regulatory approval process, the regulatory system has been put int...
The study of allelopathy has a long history, and its application to agricultural production has long been anticipated. Recently, researchers have found allelopathic plants that are now used as cover crops, and allelochemicals which may lead to new herbicides. This paper reviews three studies introduced in this symposium, and discusses the possible application of allelopathy to agriculture.

The cultivation of many crops relies on the formation of chimeric plants, where roots from one variety are grafted onto the shoot of another. A new study uncovers how two plants connect and demonstrates that the root and shoot do not contribute equally to the union.
Several studies have shown that global crop production needs to double by 2050 to meet the projected demands from rising population, diet shifts, and increasing biofuels consumption. Boosting crop yields to meet these rising demands, rather than clearing more land for agriculture has been highlighted as a preferred solution to meet this goal. However, we first need to understand how crop yields...
