Landscape Management For Sustainable Supplies Of Bioenergy Feedstock And Enhanced Soil Quality, Douglas L. Karlen, David J. Muth Jr.

Douglas L Karlen

Agriculture can simultaneously address global food, feed, fi ber, and energy challenges provided our soil, water, and air resources are not compromised in doing so. As we embark on the 19th Triennial Conference of the International Soil and Tillage Research Organization (ISTRO), I am pleased to proclaim that our members are well poised to lead these endeavors because of our comprehensive understanding of soil, water, agricultural and bio-systems engineering processes. The concept of landscape management, as an approach for integrating multiple bioenergy feedstock sources, including biomass residuals, into current crop production systems, is used as the focal point to show …

Morphological, Anatomical And Molecular Investigation Into Witches’ Broom Disease Of Mamejvo (Enicostemma Axillare), K. Abirami, Anjali Sharma, Jatindra Nath Samanta, V. S. Rana, Kunal Mandal

Kunal Mandal

Mamejvo (Enicostemma axillare Raynal) is a perennial herb with diversified health benefits. It was found to be affected by a witches’ broom disease under the field conditions at Anand, Gujarat, India. Affected plants were 53.33% reduced in height due to shortened internodes, leading to typical witches’ broom symptoms. Flower size was reduced significantly in the affected plants compared with the healthy ones and their petal color gradually turned green (virescence). Affected plants produced 2.5 times more dry herbage than the normal plants but with less active ingredient (swertiamarin). Symptomatic plants died early while root suckers from such plants failed to …

Pesticide Residue Determination In Shahr-E-Rey Tomatoes Using Quechers Method, Amin Mousavi Khaneghah Mr

Amin Mousavi Khaneghah

In this study, pesticide residues in tomato products from Shahr-e-Rey farms were measured and investigated by QuEChERS modified method. This method was on the base of the sample preparation in few steps and high speed. Measurement of pesticide residues was carried out by gas chromatograph with electron capture detector. In this study, most of the pesticides showed a recovery in the range of 70% – 120%. Limit of detection (LOD) and limit of quantification (LOQ) for all pesticides were lower than 0.50 and 1.90 μg/kg respectively. chlorpyrifos was detected in studied samples at average concentration 3.22 μg/kg, which was lower …

Evaluation On Leaf Proline Amount In Three Bread Wheat Cultivars In Presence Of Two Fertilizers Containing Amino Acids In Drought Stress, Amin Mousavi Khaneghah Mr

Amin Mousavi Khaneghah

To study leaf proline amount in presence of two fertilizers containing amino acids in drought stress on three bread wheat cultivars, a research was conducted in Ardabil IAU Research Center in 2012. To achieve this, factorial experimental design based on completely randomized block design was used. Factor A in six conditions (normal, aminol forte and fosnutren, drought, drought + aminol forte, drought + fosnutren) and factor B included three wheat genotypes (Kuhdasht, Cross Sabalan and Chmran). Results showed that there is a significant difference between The solutions on leave proline at 1 percent. Also, there was a significant difference between …

Porous Capsule Irrigation, David A. Bainbridge

David A Bainbridge

Porous capsule irrigation is a modern adaptation of buried clay pot irrigation. Research in Brazil and Mexico has demonstrated its value in improving water use efficiency. Porous capsules are more easily integrated in an irrigation network than buried clay pots.
