this study was carried out to evaluate the effects of tillage practices (with different depths) on soil penetration resistance, technical parameters and grain yield of wheat crop. the experiment was conducted as a randomized complete block design with three replications for two years. treatments included: moldboard plow fallowed by two passes of disc harrow and leveler (ct), two passes of disc ...
Conservation tillage reduces the physical movement of soil to the minimum required for crop establishment and production. When consistently practiced as a soil and crop management system, it greatly reduces soil erosion and is recognized for the potential to improve soil quality and water conservation and plant available water. Adoption of conservation tillage increased dramatically with the ad...
ABSTRACT The native field area in southern Brazil has been reduced due to cultivation, and part of the remainder is traditionally burned may increase water erosion soil degradation. In this research, chemical composition erosion, under natural rainfall, were evaluated an Inceptisol, south Santa Catarina state plateau. treatments consisted field, mowed once a year, cultivated no-tillage conditio...
A field experiment was conducted in 2007 and 2008 on a slightly acidic alfisol. Poultry manure (PM) was applied at 0, 5 t ha(-1), 10 t ha(-1), 15 t ha(-1), and 20 t ha(-1) in combination with SSP at 0, 15 kg P ha(-1), 30 kg P ha(-1), 45 kg P ha(-1), and 60 kg P ha(-1), which was replicated three times. The pH and organic C were significantly increased by the application of PM alone while availa...
Application of N fertilizer and no-tillage (NT) can increase winter wheat (Triticum aestivum L) production through improvements in plant available soil water nutrient availability. However, long-term tillage management interaction effects on uptake are not well known. The objective this study was to quantify grain yield, macronutrient removal, utilization responses application intensity. conduc...
ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1 N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...
A three-year study was conducted to analyze agronomic management in the production of winter oilseed rape (WOSR) under different tillage systems. field experiment at University’s Agricultural Experiment Station Bałcyny (north-eastern Poland), three growing seasons (2016/2017, 2017/2018, and 2018/2019). The had a 35–2 resolution III fractional factorial design with five fixed factors that were t...
in order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of calendula officinalis l., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of islamic azad university, birjand branch in 2009. in this experiment, irrigation treatments (irri...
In order to determine the effect of weeds interference and nitrogen on the sugar beet growth and yield, a field study was performed in the 2010 growing season as a split plot design based on RCBD with three replications in Hana region (Semirom, Esfahan). Treatments were four levels of nitrogen from urea source as the main factor (0, 70, 150 and 210 kg ha-1) and weed interference at five levels ...
Wheat (Triticum aestivum L.) is widely cultivated in the Mediterranean zone where plantsgenerally suffer from water stress during heading and reproductive stages. This research wascarried out at the experimental farm of the faculty of agriculture, Kafrelsheikh University usingtwo water treatments (water stress and well-watered), four N levels (0, 80, 160 and 240 kg ha-1)and two ascorbic acid le...
