The purpose of this study was to examine the capability of hyperspectral narrow wavebands within the 400–900 nm range for distinguishing five cash crops commonly grown in Northeastern Ontario, Canada. Data were collected from ten different fields in the West Nipissing agricultural zone (46°24'N lat., 80°07'W long.) and included two of each of the following crop types; soybean (Glycine max), can...

The effect of the time of catch crop (field pea) incorporation [catch crop incorporated in the autumn (A) or in the spring (B) versus plots without a catch crop (C)] on the soil enzymes related to N transformation (urease - UR, protease - PRO, nitrate reductase - NR, arginine ammonification rate - AAR), the total N and mineral N as well as microbial biomass N (MBN) contents were investigated in...

introduction intercropping, the agricultural practice of cultivating two or more crops in the same space at the same time, is an old and commonly used cropping practice which aims to match efficiently crop demands to the available growth resources (agegnehu et al., 2006; dhima et al., 2007). intercropping of chickpea with linseed reduced the chickpea yield by 60.3%, although linseed occupied on...

BACKGROUND Barley is the number one food crop in the highland parts of North Eastern Ethiopia produced by subsistence farmers grown as landraces. Information on the ethnobotany, food utilization and maintenance of barley landraces is valuable to design and plan germplasm conservation strategies as well as to improve food utilization of barley. METHODS A study, involving field visits and house...

Polarimetric decomposition techniques and inversion algorithms are developed and applied on the OPAQUE data set acquired in spring 2007 to investigate their potential and limitations for soil moisture estimation. A three component model-based decomposition is used together with an eigenvalue decomposition in a combined approach to invert for soil moisture over bare and vegetated soils at L-band...

The Borisovsky district of the Belgorod region, located in south-west forest-steppe zone Central Forest Region, was chosen for study. study covered an 11-year period, during which 3 cycles agrochemical soil survey were conducted - 2010, 2016 and 2020. Analyzing use mineral organic fertilizers, increase crop yield indicators noted. Thus, dose fertilizers (up to 1.96 t/ha) 127.2 kg/ha) made it po...

In order to study the source limitation and contribution of pre-anthesis assimilates to grain in dual-purpose (forage and grain) barley, a field experiment was carried out in Iran, Ahvaz region. The experimental design was split plot in randomized complete block with three replications. Application rates of nitrogen at four levels (60, 120, 180 and 220 kg.ha-1 N) were as main plots, while sub p...
