15 Root-knot nematodes are a growing concern for vegetable producers, because chemical 16 nematicides are gradually disappearing. Alternative techniques based on agronomic practices 17 are needed to solve the problem. This review analyzes the most recent studies related to these 18 techniques and their combinations and identifies the most effective ones. Based on an 19 agronomic point of view, ...

to determine the effective factors on yield performance of corn, 40 corn growers were selected using two ‎stages sampling method from orzooeyeh in kerman province. data were collected by questionnaires and ‎interview. frontier production function and technical unefficiency function were estimated with front. 4 ‎software.‎ using dalinous method the selected corn growers divided to three groups a...

Iron availability in calcareous soils, and Fe uptake and translocation in plants are major factors limiting the agricultural use of land. The nutritional value of crops as Fe sources for humans is often reduced due to Fe-deficiency in plants. Agronomic approaches to overcome these shortcomings include: (i) methods aimed at increasing the availability of indigenous soil-Fe; (ii) soil and/or foli...

Phytoremediation is an emerging technology that employs the use of higher plants for the cleanup of contaminated environments. Fundamental and applied research have unequivocally demonstrated that selected plant species possess the genetic potential to remove, degrade, metabolize, or immobilize a wide range of contaminants. Despite this tremendous potential, phytoremediation is yet to become a ...

Capsicum species are very important in Brazil because of economic, cultural and biological factors, and the country is considered to be a diversity center for this genus. Collection and maintenance of the genetic diversity in Capsicum are important to avoid genetic erosion. Besides the identification of species, the characterization and evaluation of accessions maintained in gene banks are of f...

population growth and the needs for protein and dairy products has urged policy makers to pay attention to efficiency policies in the livestock sector. the objective of this study is to survey the factors affecting the income of milk production, to calculate cattlemen’s technical efficiency and to determine the factors affecting the technical efficiency in the northern khorasan province. the re...

Moving averages are one of the most popular and easy-to-use tools available to a technical analyst, and they also form the building blocks for many other technical indicators and overlays. Building a moving average (MA) model needs determining four factors of (1) approach of issuing signals, (2) technique of calculating MA, (3) length of MA, and (4) band. After a literature re...
