the seedbed preparation and cereal residue present due to limit of maize (zea mays l.) growing period are a major challenge in double cropping after winter cereals in iran as: shahrekord. in this research, effects of various seedbed preparation methods and crop residuea managements on vegetative growth and yield of forage maize (ksc 704) were studied in a barley-maize double cropping during 200...
production of halophyte plants with saline water and soil and feeding them to livestock is one of the most sustainable methods of conservation in desert ecosystem regions. kochia is a high salt resistant plant that can widely use as forage for livestock in arid ecosystems with lack of appropriate water and soil resources. in order to investigate potential of forage production of five different ...
introduction multiple cropping such as intercropping plays an important role in agriculture because of maximizing beneficial interactions. intercropping of legumes and cereals is an old practice in tropical agriculture that dates back to ancient civilization. maize-legume intercrops could substantially increase forage quantity and quality and decrease requirement for protein supplements (ahmad ...
improve forage quantity and quality using organic and biological fertilizers production of important needs in dryland farming systems of the country. in this study the effects of foliar application of four different combinations of amino acid four different time steps were germinated plant growth, stem elongation, flowering and spraying all three steps above with the control treatment was carri...
Because grain is highly digestible, maize hybrids for silage production are generally chosen based on their The nutritive value of forage maize (Zea mays L.) may be improved grain yield. However, the stalk portion of the maize through genetic selection for increased rate of fiber digestion or decreased indigestible fiber concentration. To identify sources of genetic plant contains 50% or more o...
To assess the productivity potential of dual-purpose (grain-forage) sorghum promising lines at different harvesting times, a field experiment was carried-out using randomized complete block design with three replications in six locations (Karaj, Mashhad, Isfahan, Birjand, Shiraz, and Gorgan) Iran, during 2017 and 2018 growing seasons. Morphological traits and yield of seven dual purpose sorghum...
Phosphorus (P) and iron (Fe) are essential nutrients for plants. Iron availability is low in calcareous soils of Iran due to the excessive amounts of CaCO3 and high pH. Overfertilization of P fertilizers may also decrease Fe availability. The objective of this study was to evaluate the effect of P and Fe on the growth and chemical composition of corn (Zea mays L.) under greenhouse conditions. T...
To study the effect of bacterial siderophore on the second cropping of maize (SC645) under drought stress conditions, a factorial experiment was arranged in a randomized complete block design with three replications. Two irrigation treatments (75 (I1: unstressed control) and 120 mm evaporation from Class-A pan (I2: delayed irrigation)) and two siderophore application treatments (S1: with and S2...
Drought-tolerant maize hybrids currently are being marketed by several seed suppliers. Such hybrids were developed by phenotypic and marker-assisted selection or through genetic modification and tested by exposing these hybrids to various degrees of water restriction. As drought intensifies, crop yields and survival progressively decline. Water need differs among plants due to differences in ro...
One of the challenges to increase milk production in a large pasture-based herd with an automatic milking system (AMS) is to grow forages within a 1-km radius, as increases in walking distance increases milking interval and reduces yield. The main objective of this study was to explore sustainable forage option technologies that can supply high amount of grazeable forages for AMS herds using th...
