The experiment was carried out at the “La María” Campus of State Technical University Quevedo, located in Mocache canton, province Los Ríos. This consisted establishment experimental lots simple maize hybrid called “Centella”, classified as high yielding and medium segmentation, subjected to different planting densities, which corresponded following treatments: T1 (60 x 25 cm), T2 (70 cm) T3 (8...
A field experiment was conducted to investigate the effects of sewage sludge and of time lapse after sludge application on soil physical properties. Four sewage sludge treatments (0, 25, 50, and 100 ton/ha) in a complete randomized block design with three replications were applied and mixed to a depth of 20 cm. Wheat was planted and soil physical properties were measured 23, 85, 148, and 221 da...

Tillage methods are among the most successful factors in agriculture that have a significant impact on the quality and quantity of agronomic plants. To evaluate different tillage methods and urea fertilizer with nitrapyrin on total chlorophyll content, grain protein, yield, and yield components of two barley (Hordeum vulgare L.) cultivars, an experiment was conducted as split factorial in the r...
this study was done to evaluate the effect of different planting arrangements (square, lozenge and rectangular) and various concentrations of potassium sulfate (k2so4) fertilizer (0, 100, 200 and 300 kg/ha) on yield and essential oils quantitative of calendula officinalis l., a medicinal and ornamental plant. the experiment was done as a factorial in randomized completely blocks design (r.c.b.d...
The field experiment was conducted during Zaid season 2021-22 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj (U.P). soil the plot sandy loam in texture, nearly neutral reaction (pH 7.2), low organic carbon (0.48%), available N (171.48 kg/ha), P (13.6 kg/ha) K (215.4 kg/ha). treatments consisted three levels Gibberellic ...
This study aims to understand the spatial distribution of organic carbon and its sequestration potential in Tunisian soils. Soil organic carbon (SOC) stock was estimated in the 0-30 cm and to 0-100 cm soil depth for Tunisia using maps of soils and of the departments, combined with results from a soil database. The original soil classification was simplified to nine soils. Tunisia contains 24 go...
تحقیق حاضر به منظور بررسی تأثیر مقدار آب آبیاری و تراکم بذر بر عملکرد، دمای پوشش سبز و شاخص سطح برگ گیاه گندم در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه شیراز در طی سال های زراعی 87-1386 و 88-1387 انجام گردید. آزمایش بر روی گندم رقم شیراز در قالب طرح بلوک های کامل تصادفی و در سه تکرار انجام شد. تیمار های آزمایشی عبارت بودند از: پنج تراکم بذر 120، 160، 200، 240 و 280 kg/ha که سه تیمار آبیاری شامل...
The IGR, methoprene, in 3 solid (Altosid Pellet, Altosid XR Briquet and a granular) and a liquid formulation (A.L.L.) was evaluated against chironomid midges in experimental ponds. The A.L.L. was applied at 0.293 liters/ha (0.015 kg AI/ha) and at 5.86 liters/ha (0.28 kg AI/ha). The granules, pellets and briquets were applied at 13 kg/ha (0.17 kg AI/ha), 5.6 kg/ha (0.22 kg AI/ha) and one briquet...
Understanding the spatial distributions of soil water, temperature and nutrients as well their effects on maize growth grain yield is vital for optimizing drip fertigation regimes. In this study, a 2 year field experiment was conducted drip-fertigated spring with plastic mulching in arid northwestern China 2015 2016. Four irrigation levels were set: I60 (60% ETc; ETc crop evapotranspiration), I...
