Crop growth of winter rye (Secale cereale) was simulated on sandy soils in northwest Germany at the meso-scale (6 km2 catchment, 5 year rotation). Based on site-specific soil data, simulated grain yields (YMOD) were compared to observed yields OBS and the results were discussed with respect to the N balance. The mean annual yields simulated for rain-fed (3.8–7.3 t/ha) and irrigated conditions (...

Unprimed T cells transferred to heavily irradiated H-2-compatible mice cause a high incidence of lethal graft-vs.-host disease (GVHD)a in certain strain combinations (1-3). GVHD in this setting is a consequence of mature post-thymic donor T cells responding to the multiple minor histocompatibility antigen (minor HA) differences of the host. With the combination of CBA and B10.BR (both H-2~), do...

Fertilization of crops with pig manure is a common practice throughout the world. Nevertheless, due to the relatively high copper (Cu) and zinc (Zn) contents in pig manure, continuous application of pig manure could have negative effects on soil and plant. The study aimed at the impacts of long-term applying different pig manure rates (equivalently 0, 100, 250 and 500 kg total N/ha/year from 20...

Effects of different levels chemical fertilizer, farmyard manure (FYM) and bio-inoculants on nutrient content, uptake quality parameter wheat were studied. Results indicated that increasing FYM significantly enhanced content by wheat, while parameters showed significant results with application. Maximum N, P K their in grain (80.3, 11.07 25.29%, respectively) straw (32.18, 7.14 95.92%, noticed ...

The experiment was conducted at Agronomy Research Field of Bangladesh Agricultural Institute, Gazipur, during the rabi season 2018 to 2019 and 2020 find out suitable crop combination spinach (Spinacia oleracea) red amaranth (Amaranthus cruentus) with brinjal (Solanum melongena) for higher equivalent yield, monetary advantage maximize land utilization through intercropping system. Treatments wer...

A two year field experiment was carried out to evaluate the effects of municipal waste compost (C), composted cattle manure (M), and nitrogen (N) on growth and composition of weeds in a corn field in Shiraz using a split-split plot design with 3 replicates. Visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...

To evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in Islamic Azad University Agricultural Research Station, Isfahan, as a split plot in a randomized complete block design. Main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...

a filed experiment was conducted to assay the effect of nitrogen fertilization and cultivated density on essential oil content on dragonhead (dracocephalum moldavica) in semi-arid conditions in 100 km of south east of mashhad. the experiment was done as factorial based on randomized complete blocks design with three replications, factor included four levels of nitrogen fertilization (0, 50, 100...
