Olive Fertility as Affected by Cross-Pollination and Boron

Olive Fertility as Affected by Cross-Pollination and Boron

Self-compatibility of local olive (Olea europaea L.) accessions and of the cultivars "Frantoio" and "Leccino" was investigated in Garda Lake area, northern Italy. Intercompatibility was determined for "Casaliva," "Frantoio," and "Leccino," as well as the effects of foliar Boron applications (0, 262, 525, or 1050 mg.L(-1)) applied about one week before anthesis on fruit set, shotberry set, and o...

Growth and chemical composition of three pistachio cultivars as affected by soil salinity and boron fertilization

Soil Fertility, Phosphorus Fractions, and Maize Yield as Affected by Poultry Manure and Single Superphosphate

A field experiment was conducted in 2007 and 2008 on a slightly acidic alfisol. Poultry manure (PM) was applied at 0, 5 t ha(-1), 10 t ha(-1), 15 t ha(-1), and 20 t ha(-1) in combination with SSP at 0, 15 kg P ha(-1), 30 kg P ha(-1), 45 kg P ha(-1), and 60 kg P ha(-1), which was replicated three times. The pH and organic C were significantly increased by the application of PM alone while availa...

Effective pollination period for ‘Manzanillo’ and ‘Picual’ olive trees

The effective pollination periods (EPP) for ‘Manzanillo’ and ‘Picual’ olive trees have been determined in two consecutive years in irrigated orchards in California and Spain. The duration of the EPP was variable between year and cultivar. Fruit set declined gradually in response to sequential cross-pollination. Consistent differences with respect to the maximum levels of initial fruit set occur...

Detachment of Soil as Affected by Fertility Management and Crop Rotations

An experiment was initiated on Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll) in 1981 to compare the effects of fertility management and crop practices on splash detachment of soil. Experimental treatments included comparisons of crop rotations of soybean [Glycine max (L.) Merr.| after corn (Zea mays L.) (SB), corn after soybean (C), and oat/red and yellow sweetclove...
