“…In CT, intensive and shallow tillage leads to significant negative impact on soil health and quality parameter, whereas ZT facilitate buildup in soil organic matter, improve soil biological activity and soil structure due to maintenance of soil aggregates, and reduced oxidation of soil organic matter. These findings are in agreement with [69] and [70]. Results of the long-term research by [19] suggests that ZT significantly reduced bulk density and penetration resistance; increased organic carbon, saturated hydraulic conductivity, water stable aggregate, microbial biomass carbon and soil enzyme activities compared to CT. Additionally, ZT facilitates advance planting (ZT drills works well on relatively high soil moisture which is not the case for CT), regulates (buffers) soil as well as canopy temperature that helps in developing better root system (mass, density, length) which in turn results into better nutrient uptake and plant withstanding against high velocity winds at grain filling/maturity (reduce lodging) [71].…”

The objectives of the study were as follows: 1) to evaluate the GxExM for wheat genotypes; 2) to predict yield performance and identify high stable wheat genotypes in different management practices; and 3) to make genotype-specific management and high performing genotype recommendations within and across agro-ecological regions. A diverse set of twenty-one genotypes was evaluated over three years (2012, 2013 and 2014) under two levels of crop management practices (CT and ZT) across three agro-ecological regions (BR, MP and PB) of India in replicated trials. Data were analyzed with SASGxE and RGxE programs using SAS and R programming languages, respectively. Across and within a location(s), the pattern of GxExM and GxMxY interactions (respectively) among univariate and multivariate stability statistics, grouping of genotypes in divisive clusters and estimates (with a prediction interval) of genotype varied in management practice CT and ZT. Across locations, the genotypes "Munal" and "HD-2967" were the best performers and high stable in CT and ZT, respectively. Genotypes "HD-2824" and "DPW-621-50", and "Munal" may serve as diverse parents for developing high quality, climate smart, locally adapted genotypes for BR in CT and ZT, respectively. Genotypes "HD-2932", "BAZ" and "JW-3288", and "GW-322" and "HD-2967" are suitable for developing locally adapted stress tolerant genotypes for MP in management practices CT and ZT, respectively. Relatively small GxM and GxExM interactions in PB preclude in making definitive conclusions.

“…Šimanský and Tobiašová (2012) showed that higher doses of NPK fertilisers are responsible for the higher mineralisation rate of soil organic matter. It is obvious that the fertilisers applied to the soil can act diametrically opposite; the effect of their action depends on their dose, which confirmed the findings of several authors (Halvorson et al 2002;Whalen & Chang 2002). The use of organic manure caused the fastest build up of the N in the soil, followed by crop residues (in our case grass biomass).…”

The effect of fertilisation on C and N, P, K nutrients distribution in the Rendzic Leptosol in locality Nitra-Dražovce was studied. We evaluated the following treatments of fertilisation: (1) G (non-fertilised), (2) FYM (farmyard manure -dose 40 t/ha), (3) G+NPK3 (grass + 3 rd intensity of fertilisation for vineyards), and (4) G+NPK1 (grass + 1 st intensity of fertilisation for vineyards). The soil samples were taken in spring during the years 2008-2015. Obtained results showed that the content of organic carbon (C org ) decreased in the following order: G+NPK1 > FYM > G > G+NPK3 and content of total nitrogen (N t ) decreased in the following order: FYM > G+NPK3 > G+NPK1 > G. The application of NPK in the 1 st intensity of fertilisation for vineyards and added FYM build up a C org at an average rate of 370 and 229 mg/kg/year, respectively. On the other hand, contents of N t due to fertilisation declined in FYM, G+NPK3 and G+NPK1 at an average rate of 53, 22 and 20 mg/kg/year, respectively. Available P and K contents were also increased after the fertilisation of FYM and NPK. Added fertilisers (G+NPK3) significantly build up a P at an average rate of 10.2 mg/kg/year.

Little is known about the effect of management practices on net global warming potential (GWP) and greenhouse gas intensity (GHGI) that account for all sources and sinks of greenhouse gas (GHG) emissions in dryland cropping systems. The objective of this study was to compare the effect of a combination of tillage, cropping system, and N fertilization on GWP and GHGI under dryland cropping systems with various soil and climatic conditions from 2008 to 2011 in western North Dakota and eastern Montana, USA. Treatments in western North Dakota with sandy loam soil and 373 mm annual precipitation were conventional till malt barley (Hordeum vulgarie L.) with 67 kg N ha −1 (CTB/N1), conventional till malt barley with 0 kg N ha −1 (CTB/N0), no-till malt barley-pea (Pisum sativum L.) with 67 kg N ha −1 (NTB-P/N1), no-till malt barley with 67 kg N ha −1 (NTB/N1), and no-till malt barley with 0 kg N ha −1 (NTB/N0). In eastern Montana with loam soil and 350 mm annual precipitation, treatments were conventional till malt barley-fallow with 80 kg N ha −1 (CTB-F/N1), conventional till malt barley-fallow with 0 kg N ha −1 (CTB-F/N0), no-till malt barley-pea with 80 kg N ha −1 (NTB-P/N1), no-till malt barley with 80 kg N ha −1 (NTB/N1), and no-till malt barley with 0 kg N ha −1 (NTB/N0). Carbon dioxide sink as soil C sequestration rate at the 0 -10 cm depth was greater in NTB-P/N1 and NTB/N1 than the other treatments at both sites and greater in eastern Montana than western North Dakota. Carbon dioxide sources were greater with N fertilization than without and greater with conventional till than no-till. Soil total annual N2O and CH4 fluxes varied among treatments, years, and locations. Net GWP and GHGI were lower in NTB-P/N1 than the other treatments in western North Dakota and lower in NTB-P/N1 and NTB/N1 than the other treatments in eastern Montana. Net GWP across similar treatments was lower in eastern Montana than western North Dakota, but GHGI was similar. Annualized crop yield was greater in the treatments with N fertilization than without. Because of greater grain yield but low-U. M. Sainju 1043 er GWP and GHGI, no-till malt barley-pea rotation with adequate N fertilization can be used as a robust management practice to mitigate net GHG emissions while sustaining dryland crop yields, regardless of soil and climatic conditions. Loam soil reduced GWP and crop yields compared with sandy loam soil.
