This article presents a novel method for predicting the sugarcane harvesting date and productivity using three-band imaging radar. Taking advantage of working with multi-band radar, this system was employed to estimate above-ground biomass (AGB), achieving root-mean-square error (RMSE) 2 kg m−2 in crops, which is an unprecedented result compared other works based on Synthetic Aperture Radar (SA...

In the current investigation, evaporation and transpiration potential were also estimated by means of FAO Penman- Monteith evapotranspiration estimation method and Deviation from Optimum Percentage (DOP) technique by climatic elements (min-max temperature, relative humidity, wind speed and radiation) during at least 10 years statistical period regarding sunflower phenological conditions in Kurd...

sowing and harvesting date are the most important agronomic factors that we should pay attention to proper date selection for sowing date in order to achieve good crop establishment and to harvest date in order to achieve the best time for crop quantities and qualities ripening. farmers intend to germinate sugar beet seed at minimum environmental temperature. sowing date affects crop canopy dev...

Population models of white-tailed deer (Odocoileus virginianus) are used by many states to predict population levels and aid in making management decisions. Delaware did not have a deer population model, so we developed one and used it to investigate the implications of changes to the harvest. We modeled 7 changes to the harvest regime and compared these changes to the base line of no changes t...

in order to determine the appropriate plant density in different planting dates for sweet corn cultivar ksc403su, an experiment was conducted using a randomized complete block design in split plot lay out with three replications at seed and plant improvement institute in karaj in 2006. three planting dates (22 may, 5 june and 22 june) were assigned as main plots and three plant densities (65000...

In 1994, its second full production year, field-grown meristemmed 'Black Mitchum' peppermint performed differently than in 1993, when compared with a non-meristemmed treatment in a field trial at the OSU-COARC. The difference between years may be partly attributed to better meeting the fertility and soil moisture needs of meristemmed plants in 1994. Plants were not moisture-stressed near harves...

During the 1991 and 1992 soybean growing seasons, field plots were established in South Carolina to study the effect of planting date on at-planting nematode densities and subsequent yield losses caused by Hoplolaimus columbus. The susceptible and intolerant soybean cv. Braxton was planted on five dates from to May to 28 June in 1991 and from 12 May to 28 June in 1992. Nematodes were recovered ...

Blackcurrant leaves are an essential source of phenolic compounds and this study investigated their variation relative to leaf positions and harvest date. The phenolic content varied between harvest dates, although leaf position on the shoot and interactions also played an important role. The contents of quercetin-malonyl-glucoside, kaempferol-malonyl-glucoside isomer and kaempferol-malonyl-glu...
