Two experiments were conducted to determine the seasonal effects of N fertilizer (NF) and defoliation interval (DI) on specific N fractions within annual ryegrass (AR) and overall usage of AR N by growing lambs. In Exp. 1, NF (0, 112, 224, and 336 kg of N/ha) and DI of 2, 4, or 6 wk were factorially applied to AR plots. Both decreasing DI and increasing NF increased N levels in AR in a manner t...
BACKGROUND When producing biofuels from dedicated feedstock, agronomic factors such as harvest time and location can impact the downstream production. Thus, this paper studies the effectiveness of ammonia fibre expansion (AFEX) pretreatment on two harvest times (July and October) and ecotypes/locations (Cave-in-Rock (CIR) harvested in Michigan and Alamo harvested in Alabama) for switchgrass (Pa...
(1) Background: The aim of the study was to use innovative sensor technology for non-destructive determination and prediction of optimum harvest date (OHD), using sweet cherry as a model fruit, based on different ripening parameters. (2) Methods: Two cherry varieties in two growing systems viz. field and polytunnel in two years were employed. The fruit quality parameters such as fruit weight an...
long season and high temperature during spring in hot and dry areas has led to tendency for autumn planting. in order to evaluation of chickpea (cicer arietinum l.) autumn planting possibility, a field experiment was done at the agricultural faculty and natural resources of saravan research field in 2010. experimental design was done as split plots based on randomized complete block design with...
The European pear is a climacteric fruit species characterised by high storability. ‘Conference’ can be stored in CA (controlled atmosphere) room without major losses for half year. However, storage to successful, the must harvested when fully developed before it enters climatic maturation phase. Among various methods used determine optimal harvest date, degree-day method, which relies on sum o...
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...
