There is little information about the effects of ethephon ripening hormone on the yield of sweet sorghum in Thailand. Therefore, this study aimed to evaluate the impact of ethephon hormone applied at different growth stages of three cultivars of sweet sorghum on its growth and yield. The experiment was conducted from December 2016 to May 2017 at a research plot of the Faculty of Agricultural Te...
in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...
Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and...
Rosemary (Rosemarinus officinalis L.) is a well-known medicinal and essential oil plant, utilized by humankind since ancient times. The objective was to determine the effect of steam distillation time (DT) and material (dry or fresh biomass) on essential oil yield, composition, and bioactivity; and to develop regression models that can predict oil yield and composition at specific DT. The oil y...
the study was carried out to examine the effects of urban sewage and nitrogen fertilizer levels on yield quantity and quality forage of sweet corn was evaluated in yasouj at 2009. the main experimental factor consisted of 5 irrigation levels including: common irrigation water without sewage effluent until the end of plant growth (i1), the first half of plant growth period with sewage effluent a...
regarding increased limitations on fresh water availability in agriculture and the necessity of finding solutions for management of unconventional waters, some scenarios for using saline water were assessed for forage maize. saltmed model, as an integrated approach, can be used for a variety of irrigation systems, soil types, soil stratifications, crops, water management strategies (blending or...
Cultivation of legume species as the second crop in rotation with rice and using plant growth promoting bacteria can be a good approach to improve rice production sustainability. This experiment was carried out to evaluate the effect of plant growth promoting bacteria on accelerating vegetative growth of crimson clover (Alborz 1) and rice (Hashemi) yield in a rice-based cropping system. A facto...
this research was assigned to study the top crop yield potential and nutritive value of jerusalem artichoke (helianthus tuberosus), using a completely randomized designed with three treatments and four replications. the forage was cut at three growing stages where plant high, fresh and dry forage yield and leave/steam ratio were recorded. first and second cut were made when the plant heights we...
High performance is the most important expectation from concrete which is commonly used in today’s construction technology. To form a high performance concrete “HPC”, two fundamental properties are required. These properties are optimization of the materials used to form the concrete and the workability of fresh concrete during shaping. Many scientists have used rheological properties in conjun...
Accurate estimation of rice biomass and yield estimation are not only important for rice cropping management, but also for quantitative understanding of carbon cycle in agricultural ecosystems. In this study, the fresh biomass is estimated by using broadband indices from multispectral sensor AVNIR-2 on board ALOS platform. A field campaign was carried out during June 2010 in northern part of Ir...
