The documentation process is very important for identifying yield constraint factors and yield gap. For this purpose, all managing practices were recorded by monitoring of paddy rice fields in Sari region, Iran from 2015 to 2016. Field identifications were undertaken in such a way that they included all the main production procedures with variations in management viewpoints. The results reveale...

The aim of this experiment was to evaluate the biomass yield and chemical composition of the essential oil of clove basil in response to doses of broiler litter (0, 5, 10, 15 and 20 t ha-1) added in presence of triple superphosphate (200 kg ha-1) or without it. Before the first harvest, the height of the plants increased significantly (34.42 cm) when 15 tonnes ha-1 broiler litter were added to ...

Soil carbon (C) sequestration in tilled and nontilled areas can be influenced by crop management practices due to differences in plant C inputs and their rate of mineralization. We examined the influence of four cover crops {legume [hairy vetch (Vicia villosa Roth)], nonlegume [rye (Secale cereale L.)], biculture of legume and nonlegume (vetch and rye), and no cover crops (or winter weeds)} and...

This study underscored an underexploited crop, blue panic grass as a potential crop for hot and saline regions. It investigated feed value of the crop at two growth stages, before flowering (BF) and after flowering (AF), and under different levels of humic acid application (HA, at 0, 15, 30, 45, 60, 75, and 90 kg ha). Significant (P < 0.05) effects of different growth stages, HA while non-signi...

During 1996–2006, the Ministry of Agriculture and Forestry in Finland (MAFF), MTT Agrifood Research and the Finnish Geodetic Institute performed a joint remote sensing satellite research project. It evaluated the applicability of optical satellite (Landsat, SPOT) data for cereal yield estimations in the annual crop inventory program. Four Optical Vegetation Indices models (I: Infrared polynomia...

Present study was carried out during 2018–19 and 2019–20 at ICAR-Directorate of Rapeseed-Mustard Research, Bharatpur, Rajasthan to evaluate the effect nitrogen (N) sulphur (S) nutrition on production efficiency, water productivity, economics Indian mustard [Brassica juncea (L.) Czern &amp; Coss.] under irrigated conditions. The experiment conducted in a split plot design with 5 levels (0, 60, 8...

Three different formulations of Bacillus sphaericus viz, Spherimos, Vectobac and Spherifix, were evaluated for their efficacy and residual activity against Culex quinquefasciatus breeding in polluted disused wells. Spherimos, a flowable concentrate formulation, exerted 96-100% control when treated at the dosage of 10 l/ha for 17 days, whereas the effective residual activity lasted up to 67 days...

The formation and persistence of methylated purines was determined in mice that received a single s.c. injection of 1,2-[14C]dimethylhydrazine (15 mg/kg) and were allowed to survive for 12 or 60 hr. In mice with a low susceptibility to dimethylhydrazine-induced colon carcinogenesis (C57BL/Ha), concentrations of 7-methylguanine and O6-methylguanine in DNA of colon, ileum, and kidney were 40 to 6...

a field investigation was conducted to evaluate the effect of n and k fertilizers on qualitative and quantitative changes of potato tubers during five months of storage. this study was carried out in three replications at five levels (0, 60, 120, 180 and 240 kg/ha) of nitrogen and three levels (0, 75 and 150 kg/ha) of potassium fertilizer during 2004-2006. measurements were recorded monthly. th...

application of biofertilizers, especially plant growth promoting rhizobacteria (pgpr) is one of the most important strategies for plant nutrition compared to chemical fertilizers, especially in sustainable management of agroecosystems. in order to evaluate the effect of pesodomonas bacteria strains and chemical phosphate fertilizer on yield and yield components of wheat the kavir cultivar an ex...
