Seventeen warm season annual forage options were evaluated as livestock feed to be grazed, hayed, ensiled, or left a cover crop. Treatments planted in mid-May and terminated late September with one harvest for silage, two hay cuttings, three grazing rotations. One additional treatment was unharvested serve Biomass production cost produce final outputs determined. Even restricted rainfall during...

ABSTRACT Special corn is cultivated all year conventionally round; however, its productivity increases when grown under a no-tillage system (NTS). This study aimed to evaluate the agronomic performance of sweet and green residues different cover crops NTS implantation stages. Two experiments were carried out in randomized block design, with four replications, each three areas. The consisted eva...

Sunn hemp (SH), Crotolaria juncea, is known to suppress Rotylenchulus reniformis and weeds while enhancing free-living nematodes involved in nutrient cycling. Field trials were conducted in 2009 (Trial I) and 2010 (Trial II) to examine if SH cover cropping could suppress R. reniformis and weeds while enhancing free-living nematodes if integrated with soil solarization (SOL). Cover cropping of S...

Decomposition processes and mineralization are essential to determine the time deploy manage species in consortia or rotations. The aim of this article was study dynamics biomass decomposition release macronutrients plant residues Fabacea. used were: jack bean (Canavalia ensiformis), pigeon pea (Cajanus cajan), dwarf mucuna (Mucuna deeringiana) sunn hemp (Crotalaria juncea). experiment conducte...

The Sunn-pest, Eurygaster integriceps Puton (Heteroptera: Scutelleridae), is the most important insect pest of wheat and barley in Iran. A demographic study was carried out in order to determine the effect of temperature on life history parameters of the pest. Life tables were constructed at four constant temperatures: 22, 25, 27, and 30 ± 1° C using Mahdavi wheat kernels as food. Finite and in...
