This work aimed to evaluate the variability in distribution of root system among genotypes C. canephora cv. Conilon and indicate management strategies for a more efficient mineral fertilization. Root was evaluated six genotypes. The experimental design randomized blocks with three replications. Soil monoliths measuring about 27 cm3 were collected at different soil depths, row distances nine int...

in order to investigate the possibility of reducing herbicide usage in combination with plant density and planting pattern, a field experiment was designed in chenaran, khorasan razavi, on 2010. the experiment was split plot treatments based on rcbd with three replications in factorial arragement. the treatments included of 3 level of plant density (100000, 120000 and 140000 plants ha-1) and 2 ...

A 2-year field study evaluated the influence of subsoiling and nematicide application, alone and in combination, on the growth and yield of field corn in a sandy soil in north-central Florida. The field had a 25-30-cm-deep tillage pan (plowpan) and was infested with Belonolaimus longicaudatus, Hoplolaimus galeatus, Trichodorus christei, and Pratylenchus spp. Subsoiling increased corn yield both...

increasing level of carbon dioxide co2 due to industrial activity is primarily cause of global warming. planting artoplex lentiformis can help to reduce atmospheric co2 buildup partly replacing use of fuels and by carbon storage. the objective of this study was to determine the effects of row spacing on carbon storage. a split- plot design with three replications included three row spacing (2×2...

This paper shows some preliminary results on the exploitation of COSMO-SkyMed (CSK) data for the characterization of agricultural fields. In particular, we analyze the impact of the planting row direction on to the radar backscattering response. We considered two different crop types, namely carrots and potatoes, and we grouped them in two subsets, the first including fields with row direction ...
