Approaches Used to Compare Cropping Systems

The development of sustainable cropping systems using alternative cropping systems is one of several newer, areas of specialized research that compare mixed-cropping practices with the current dominant sole-cropping ones. In order to assess this diversity, a general approach is needed for comparing...

Efecto de la salinidad sobre el aceite esencial y la biomasa de dos genotipos de orégano (Origanum spp.) cultivados en invernáculo

En zonas áridas o semiáridas donde la calidad y/o cantidad de agua de riego es inadecuada para eliminar el exceso de sales solubles, la salinidad podría afectar el rendimiento y/o calidad de los cultivos de orégano. El objetivo de este trabajo fue evaluar la...

Effectiveness of Organic Wastes as Fertilizers and Amendments in Salt-Affected Soils

Excessive salt rate can adversely influence the physical, chemical, and biological properties of soils, mainly in arid and semi-arid world regions. Therefore, salt-affected soils must be reclaimed to maintain satisfactory fertility levels for increasing food production. Different approaches have...

Greenhouse Substrates and Fertilization

Everyone seems to be searching for the ideal plant mix. The criteria are simple: make a mix with good aeration, that doesn’t dry out too quickly, can be used in all cell sizes, contains all the nutrients necessary, can be used for all species of and stores indefinitely. All that is needed is...

Effect of Different Tillage Methods on Crop Yield and Yield Components of Watermelon

A two year field experiment was conducted to investigate the response of crop yield and yield components of watermelon to different tillage methods in the arid lands of Iran. Tillage treatments in the study were moldboard plow + two passes of disk harrow as conventional tillage (CT), two passes of...

Managing the almond and stone fruit replant disease complex with less soil fumigant

As much as one-third of California's almond and stone fruit acreage is infested with potentially debilitating plant parasitic nematodes, and even more of the land is impacted by Prunus replant disease (PRD), a poorly understood soilborne disease complex that suppresses early growth and...

Organic Vegetable IPM Guide

Interest in nonchemical pest control has increased over the past several years. To some people, this means the same as “organic farming,” which implies nature’s way. But in this publication, we talk about controlling pests without chemicals, or at least fewer chemicals. This...

Nutrient extraction of tomato (Solanum lycopersicum L.) in mixtures of volcanic rock with fresh and recycled sawdust

Hydroponic or greenhouse production systems allow daily fertilization of vegetable crops, depending on its life cycle, substrate and available water. Sawdust is currently being used successfully as substrate in crop production and for this reason we evaluate the effect of mixtures (v/v) of...
