The common method of puddling is using a conventional tiller which requires long time of soil operations.In this study, the effects of tillage equipment on moisture characteristic curve of a paddy soil were investigated. The treatments included tillage equipment (T1: conventional tiller, T2: rotary puddler, T3: cone puddler, T4: tractor mounted rotivator) and number of puddlings (P1: puddling o...
In order to evaluation of morphological selection criteria for salt tolerance screening in wheat (T. aestivum L.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. Salinity treatments involved 4 levels: S=1.3dSm-1 (control), 5, 10, 15 dSm-1 from calcium chloride and sodium chloride with 10:1 (Na: Ca ratio) and another facto...
In a greenhouse research, the effects of soil water conditions, sewage sludge and chemical fertilizers on growth characteristics and water use efficiency of rice (Oryza sativa L. cv. Ali Kazemi) were studied in a loamy sand alkaline non-calcareous soil. The study was performed as a factorial experiment in a randomized complete blocks design including soil water conditions in three levels (conti...
Pasture is the main source of nutrition for New Zealand ruminant livestock industry. Changing climatic conditions and relentless intensification are putting ability pastures to provide that under pressure. Recent understanding interactions between grazing management life cycle roots, leaves seedheads pasture species creates further opportunities increase resilience. Root production directly rel...
Grain yield in wheat (Triticum aestivum L. emend. Thell.) is highly dependent upon the number of spike-hearing tillers produced by each plant. Soil salinity can greatly decrease their number and productivity. Knowing the contribution of specific tillers is essential for breeding salt-tolerant genotypes and for developing wheat growth simulation models. Our objective was to determine the effects...
Shading (S), bioregulators (BR) and biostimulants (BS) techniques are alternatives that promote sprouting production of grass. The objective was to evaluate the effect S, BR BSt on growth yield Mombaza grass in Ecuador. A complete randomized block design, with split plot arrangement three replications, used, main represented by condition S (S1: full solar exposure, S2: shade trees) secondary on...
