The aim of the study was to evaluate dependence potato crops on level irrigation in three mesoregions Poland. field experiments were carried out 2009–2011 according an obligatory methodology for evaluation crop cultivars. Three factors tested: two cultivation practices (with and without as control), five cultivars, locations (Masłowice, Szczecin-Dąbie, Węgrzce). conducted randomized blocks trip...

Planting date of soybean, Glycine max, influenced winter survival of Pratylenchus brachyurus in microplots at two locations in North Carolina. Delayed planting resulted in a linear decrease (P = 0.05) in the numbers of P. brachyurus at soybean harvest. Effects of planting date on nematode numbers persisted over winter, indicating that survival in the absence of a host is density independent. Co...

Harvest and post-harvest operations constitute principal constraints to rice production, especially in irrigated systems, because of the larger yield that has to be handled. Post-harvest crop losses of up to 35% have been reported and attributed to inefficiency of manual threshing of rice by small-scale farmers. This leads to poor grain quality and rejection of locally produced rice. The Africa...

Effects of 1-aminoethoxyvinylglycine hydrochloride (AVG or Aviglycine HCl or ReTain) and α-naphthalene acetic acid (NAA) on fruit retention, fruit quality, eveloved ethylene, and respiration in ‘Rome Beauty’ and three ‘Delicious’ apple cultivars (Malus domestica Borkh.) were studied.  The experimental trees were treated with either AVG, applied at 120 g a.i. per 935 L. ha-1 or NAA, applied at t...
