A field investigation was undertaken during Kharif (June–September) 2019 at Agriculture Research Institute, Professor Jayashankar Telangana State University, Rajendranagar, Hyderabad, Telengana State, India with an object to evaluate the CROPGRO-Tomato model under different dates of planting and cultivars.The experiment carried out (02nd Jul, 12th 22nd 02nd Aug, 11th 23rd 03rd Sep 13th Sep) as ...

the percentage of fat in liver wet and dry matter, liver moist and dry matter and their relationship were investigated based on species, sex and age of 384 slaughtered animals including 114 cows, 100 buffaloes, 147 sheep and 23 goats from 2008 to 2010 in urmia, iran. mean percentage of fat in liver wet and dry matter, and liver dry matter in cows were 3.6%, 1.1%, 29.7%, buffaloes were 5.3%, 1.5...

To investigate a model to simulate wheat dry matter accumulation, three wheat cultivars with different tillering abilities were grown at three densities each in a field experiment. Five simulation models with high correlation coefficients for relative dry matter accumulation were established by the method of normalized. Among these models, the Richards equation was the best in fitting and forec...

One-time fertilization with controlled-released fertilizer (CRF) is a promising way for reducing labor cost, increasing nitrogen use efficiency (NUE) and alleviating environmental pollution in winter wheat (Triticum aestivum L.) cultivation. However, CRF release characteristics are related to various factors such as soil properties, temperature precipitation, further study needed developing sui...

BACKGROUND AND AIMS The morphological structure of anthetic carpels of Brasenia (Cabombaceae), a member of the phylogenetically basal ANITA grade, has not been studied before. The carpel has a long stigmatic crest on the ventral side and could give the impression of a conduplicate structure. This is in contrast to the carpel structure in other genera of the ANITA grade. Therefore, a study of ca...

Controlled-release nitrogen fertilizer (CRNF) is expected to meet the nutrient demands for crop growth with single application, so as achieve high-yield, high-efficiency, and labor-saving cultivation. However, under current CRNF practices, a application of in winter wheat (Triticum aestivum L.) usually fails satisfactory effects due insufficient (N) supply later stage, contributing premature le...

Silicon in forage reduces dry matter digestibility and may reduce grazing preference. Two studies were conducted with the following objectives: (1) to evaluate a method of determining grazing preference, and (2) to characterize the distribution and solubility of silicon in 31 accessions of C-3 grasses and relate these traits to grazing preference and estimated forage digestibility. Forage sampl...

a field study was conducted to evaluate the agronomic response of eight isolines of cv. clark on a clay loam soil (at karaj-iran, 35048´) to four plant population densities of 11.3, 18.5, 68.5, and 103.4 plants per square metre. significant yield increase was obtained as a result of higher plant density. differences among the cv. clark isolines were significant (p

Present experiment was conducted (2015-16 and 2016-17) comprising different levels of water stress environmental conditions for the model parametrization validation Info Crop-wheat v2.1 model. The calibrated validated popular wheat variety HD-2967 under semi-arid conditions. important genetic coefficients were generated fine-tuned simulating phenology, leaf area index (LAI), dry matter yield cr...

kochia is a halophyte plant and is a good source of forage for livestock under saline irrigation. in order to investigate the salinity effect on morphological and forage characteristics of kochia, an experiment was conducted. three saline waters (5.2, 10.5 and 23.1 ds m-1) and three kochia ecotypes (birjand, borujerd and sabzevar) were allocated as main and sub plots, respectively, in a split p...
