stomata are closed by moisture stress, reducing carbon assimilation and yield production with dry land agriculture. relative 13c to 12c molar ratio assimilation by a plant is a function of time stomata remain open during plant life time, itself a function of moisture stress. the purpose of this study was to test the existence of any relationship between stomatal conductance and assimilation rat...

in order to determine the effect of irrigation interval and mulch on growth of olive an experiment was carried out in dallaho olive research station at sarepole. a split plot experiment was used based on a completely randomized design with three replications and two factors (mulch and irrigation interval). each experiment unit consists of 4 trees. land preparation was done in february 2005 in a...

Cotton is a global cash crop with significant contribution in the world economy. Optimum nutrient and water supply are most important for sustainable cotton production under warmer dry environments. Field experiments were carried out to evaluate cumulative impacts of various nitrogen doses mulches on semi-arid conditions during 2018 2019. Four doses; 0, 70, 140, 210 kg ha−1 three types mulch: c...

Field experiments were carried out to study the interactive effects of plastic mulch and tillage method on yield and quality of tomato (Lycopersicon esculentum) during 2007 and 2008 growing seasons. Mulch levels in the study were plastic-mulching (PM; black plastic mulch) and no-mulching (NM) and tillage treatments were conventional tillage (CT; moldboard plowing + two passes of disk harrowing)...

Weed control is an important aspect during the first few years of Christmas tree establishment, as weed competition directly relates to rate growth this time. The objectives study were evaluate efficacy organic mulch and herbicide combinations determine their phytotoxic effects on four different species trees establishment stage: Fraser fir (Abies fraseri (Pursh) Poir), blue spruce (Picea punge...

Intensive tillage with no crop residue after rice harvest in conventional wheat cultivation increases the turn around time, delays sowing and affects yield. A field experiment was carried out to assess effect of dates, establishment methods mulching their interaction on growth, productivity profitability spring at agronomy farm AFU, Rampur Chitwan, Nepal from November 2020 April 2021. The laid ...

In this study, changes in soil moisture and salinity contents in drip irrigation combined with white and black plastic mulches compared to no mulch (control) was evaluated. The experiment was carried out in two commercial pistachio orchards (Ohadi cultivar) with irrigation frequencies of 8 to 12 days with a total water consumption 4100 and 6170 m3ha−1. The study was conducted in a complete rand...

the trial randomized complete block design with four replications in summer 1394 on a farm in the village of dotuyeh, kahrizak district located in the share ray to study the effects of different methods of weed control on qualitative and quantitative yield forage corn varieties (sc.704) do was. the experiment consisted of black plastic mulch, on black plastic mulch silver, mung bean living mulc...

Abstract Living mulches are cover crops grown simultaneously with and in close proximity to cash crops. Advantages of living over dead may include increased weed suppression, reduced erosion leaching, better soil health, greater resource-use efficiency. synthetic enhanced agroecosystem biodiversity suitability for a wider range cropping systems. A major disadvantage this practice is the potenti...
