The use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. One of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. This research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

abstract methods of tillage and organic matter affect root growth and distribution and therefore nutrient uptake by plant and its growth. this study was performed consecutive two years. tillage treatments included disk harrowing + two disk harrowings as reduced tillage (15 cm plowing depth) and moldboard plowing + two disk harrowings as conventional tillage system (30 cm plowing depth). also, t...

root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...

this study was performed in order to evaluate the effects of application of super absorbent on the yield and water use efficiency of cucumber under deficit irrigation conditions in greenhouse. plants cultivated in plastic pots and irrigation emitter with four liters per hour discharge was performed. three levels of irrigation water height (10, 8.3 and 6.2 mm day-1) were used as the main factor ...

one of the most important goals of sugar beet cultivation is to achieve high seedling emergence and establishment under water deficit conditions. in this experiment irrigation of the seed bearing plants was cutoff in four periods of 750, 1000, 1250 and 1500 gdd after schtechlings were planted and the seeds were formed and grown under water stress. the experiment was carried out as a randomized ...

Combined application of organic and inorganic amendments was known to play a significant role in improvement of soil properties. A field experiment was conducted to explore the effects of gypsum, farmyard manure and commercial humic acid application on the amelioration of salt affected (saline sodic) soil. During this study, soil pH, electrical conductivity, sodium adsorption ratio, responses o...

Long-term use of drip irrigation technology may lead to root degradation and affect shoot growth and yield. A field experiment was conducted to investigate aboveand belowground growth responses to drip irrigation under mulch film (DI) in comparison to flood irrigation under mulch film (FI) in cotton. The monolith method was used to harvest roots at seven timepoints in the growth periods, and th...

on-farm experiments were designed to investigate the response of maize establishment and grain yield to variation in tillage systems. the tillage treatments included arara ploughing followed by zig-zag harrowing and arara ridging (t1); emcot ploughing fol-lowed by zig-zag harrowing and emcot ridging (t2); mouldboard ploughing followed by disc harrowing and mouldboard ridging (t3); disc ploughin...
