Tomato breeding has been tremendously efficient in increasing fruit quality and quantity but did not focus on improving herbivore resistance. The biosynthetic pathway for the production of 7-epizingiberene in a wild tomato was introduced into a cultivated greenhouse variety with the aim to obtain herbivore resistance. 7-Epizingiberene is a specific sesquiterpene with toxic and repellent propert...

The transforming agri-food sector is an important contributor to employment generation in rural areas of lower-income countries. However, little attention has been paid the question how technology affects quality and quantity sector. In this paper, we provide first empirical evidence rise greenhouse farming changes labor demand (i.e., number employees), using large-scale nationally representati...

Chinese solar greenhouse (CSG) is universally applied in northern China for producing horticultural products. CSG is characterized by the unbalanced structures with an arched front roof face to the south side and a thick wall as well as back roof in the north side. Such structures affect light distribution in the greenhouse. This study aims to investigate the light distribution properties in CS...

this study was conducted to evaluate the responses of two greenhouse tomato cultivars to nutrient solutions' electrical conductivity (ec). two cluster type greenhouse tomato cultivars (razan and ergon) were grown in perlite in a glasshouse hydroponic system. the grown plants were daily fed with either constant ec nutrient solutions (ecs 2, 3 ds m-1) or nutrient solutions of alternatively c...

for investigating of o. aegyptiaca control in tomato with sulfosulfuron and glyphosate and evaluating the efficacy, dose and time of application, some studies were conducted in 2011 at aarhus university of denmark. at first, the efficacy of sulfosulfuron (0.029, 0.147, 0.735, 3.676 and 18.378 mg per lit) and glyphosate (0.023, 0.117, 0.587, 2.935 and 14.676 µl per lit) on egyptian broomrape see...

In this study, the comparative advantage of main agricultural products and its relation to cropping pattern was studied in Ilam Province. For data analyzing the comparative advantage and government policies effects indices, Policy Analysis Matrix (PAM) were used. The obtained results for the comparative advantage indices of Domestic Resource Cost (DRC), Social Cost Benefit (SCB) and Net Social ...

Functional male sterility in tomato (Solanum lycopersicum L.) positional sterile ps and ps-2 lines provides a good facultative sterility system for F1 hybrid seed production. In order to elucidate the observed variability in the trait stability, expressivity was observed in a comparative multi-year study (2008 – 2012) across seven ps and two ps-2 tomato lines. Tomato lines undergoing the study ...

Leaf temperature represents the mixed effects of solar radiation, temperature, and CO2 enrichment on potential production greenhouse vegetables. However, smart farm applications that monitor account for changes in leaf are limited. This study developed new hardware software components sensing integrated into a conventional system. We demonstrated system to temperatures improve crop yield at two...
