Accumulation of dry matter in siliqua, number of siliqua per plant, length of siliqua and seeds per siliqua of rapeseed (Brassica campestris L.) plants were studied under three irrigation levels (no irrigation, one irrigation at 30 DAS and two irrigations at 30 and 60 DAS) and three row spacing (20 cm, 30 cm and 40 cm). Th e experiment was carried out at Sher-e-Bangla Agricultural University (S...
the purpose of this paper was to determine the factors affecting farmers’ satisfaction from water users associations (wuas) in the harran plain-turkey. the data used in this study come from a sample of 378 farmers among 23,204 in the şanlıurfa-harran plain. they were chosen via simple random sampling method and interviewed face to face. sampling was conducted in 52% of the settlements. to analy...
Development of best management practices (BMPs) such as conservation tillage and winter cover crop to mitigate runoff and reduce dissolved chemicals in irrigation runoff is an important objective for controlling surface water pollution attributable to agricultural activities. In this study, the effect of standard tillage (ST), STwith winter cover cropping (STCC), and no-till (NT) management pra...
The experiment was carried out at Agronomy Field laboratory, Department of Agronomy and Agricultural Extension, university of Rajshahi, to study the effect of irrigation and sowing method on yield and yield attributes of mustard. The experiment consists of two factors i) irrigation viz. no irrigation (I0), one irrigation (I1)and two irrigations (I2) ii) sowing method viz. line sowing method (M1...
Does it matter in what order the four irrigations are conducted in the caloric test? It has been suggested that warm water (44 degrees C) elicits stronger reactions than does cold water (30 degrees C), which might be explained simply by slight differences in water temperatures. However, if it can be shown that starting with cold water diminishes the difference between the warm and cold irrigati...
PURPOSE OF REVIEW Nasal irrigations are often mentioned as adjunctive measures in treating many sinonasal conditions. Despite their widespread use, much mystique and uncertainty exist about the indications and therapeutic mechanisms of nasal irrigations. Anecdotal evidence and poorly controlled studies add to the confusion. Recent evidence challenges some of the assumptions underlying the use o...
Dynamic changes in water and salinity in saline-alkali soils after simulated irrigation and leaching
Soil salinization is a global problem that limits agricultural development and impacts human life. This study aimed to understand the dynamic changes in water and salinity in saline-alkali soil based on an indoor soil column simulation. We studied the changes in the water and salt contents of soils with different degrees of salinization under various irrigation conditions. The results showed th...
A field experiment was conducted over 2 years to evaluate the gas exchange, water relations and water use efficiency (WUE) of wheat under different water stress and nitrogen management practices at Crop Physiology Research Area, University of Agriculture, Faisalabad. Pakistan. Four irrigation levels, i.e. one irrigation (Irrigation at tillering stage), two irrigations (Irrigations at tillering ...
A field experiment was conducted in sandy loam soils to study the Growth and Yield parameters of six different crops with limited number irrigations under a zero-till system rice fallows during rabi, 2021-22 at Agricultural College Farm, Naira. The laid out split-plot design, replicated thrice three irrigation levels viz., two (I1), (I2) four (I3) assigned main plots fallow Maize (C1), Sorghum ...
Profitability assessment has prime importance for every crop husbandry practice and cultural operation. For this purpose, two field experiment was carried out to investigate the response of spring planted sunflower hybrids to different irrigation levels/schedules and foliar application of abscisic acid. Two studies were done at the Agronomic Research Farm, University of Agriculture, Faisalabad,...
