to evaluate the effect of cover crops, tillage systems and nitrogen (n) application rates on yield of forage sorghum (cv. kfs3), a factorial–spilt plot arrangement based on randomized complete block design with four replications was carried out at the research farms college of agriculture and natural resources, university of tehran, karaj, during the growing seasons of years 2005 and 2006. comb...

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...

A field experiment was conducted during the rainy (kharif) season of 2019 at ICAR-Indian Agricultural Research Institute, New Delhi, to study effect different tillage and weed-management practices on productivity, water energy-use efficiency pearl millet [Pennisetum glaucum (L.). R. Br.]. The laid out in a split-plot design, with main plot, viz. conventional (CT), zero (ZT), + residue (ZT R) 3 ...

The effect of tillage, crop establishment and weed management was studied on theperformance of wheat grown after soybean at New Delhi, India during 2010-11 to 2011-12.Sixteen treatment combinations involved 2 tillage, viz. conventional tillage (CT) and zero tillage(ZT), two crop establishment practices, viz. raised-bed and flat-bed and four weed management,viz. isoproturon + hand weeding, mesos...

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...

Southeastern USA production is limited in Acrisols (Paleudults and Kandiudults) because they have high strengths and low water holding capacities. Production systems with crop rotations or deep tillage before planting were compared with less intensive management. Production systems included double-crop wheat (Triticum aestivum L.) and soybean (Glycine max L. Merr.) that were drilled in 0.19 m-r...

In subtropical regions, we have an incomplete understanding of how long-term tillage, stubble, and nitrogen (N) fertilizer management affects soil biological functioning. We examined a site managed for 50 years using varying tillage (conventional till (CT) no-till (NT)), stubble (stubble burning (SB) retention (SR)), N fertilization (0 (N0), 30 (N30), 90 (N90) kg ha?1 y?1) to assess their impac...

in order to study the effects of nitrogen and complementary irrigation on yield and its components of rainfed barley sahand cultivar, an experiment was conducted on split plot based on randomized completely block design with four replication in baft area at 2009-2010. factors were: four levels of nitrogen (0, 20, 40 and 60 kg/ha as pure nitrogen) from urea source as factor b and four levels of ...

An experiment was conducted during the rainy (kharif) and winter (rabi) seasons of 2017–18 2018–19 on sandy loam soil Agricultural College, Acharya N.G. Ranga University, Bapatla, Andhra Pradesh, to evaluate economics rice (Oryza sativa L.)–zero tillage finger millet [Eleusine coracana (L.) Gaertn.] cropping system. The laid out in a randomized block design replicated thrice season rice, each t...
