Nitrogen dynamics in field grown comice pears

Creator:: Sanchez, Enrique E.
Abstract:: The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was remobilized into new...

Relationship of boron to reproduction in hazelnut (Corylus avellana L.)

Creator:: Shrestha, Gyan Kumar
Abstract:: Boron sprays produced fruit set increases in 'Barcelona' hazelnut orchards in 1984 and in 1985. The absolute fruit set was correlated with leaf B content but not with nut B. With relative fruit set (RFS), B content of nuts in May (r = 0.63**) was more strongly related to set...

An evaluation of the Diagnosis and Recommendation Integrated System (DRIS) on hazelnuts (Corylus avellana) in Oregon

Creator:: Alkoshab, Othman
Abstract:: This study evaluates Beufil's Diagnosis and Recommendation Integrated System (DRIS) on hazelnuts. Although sufficiency ranges are currently the main approach for fertilizer recommendations in Oregon, DRIS enhanced nutritional interpretations, and might alter recommendations. Reference values (DRIS norms) were developed using 15 years of published and unpublished field data. DRIS indices...

Chilling and nutritional requirements of fruit trees in Yemen

Creator:: Alkoshab, Othman
Abstract:: A portion of this study was initiated to provide the basis for implementing a chill unit accumulation procedure in Yemen. Most continuous or daily minimum, maximum temperature models severely underestimated chilling units, and slight modifications offered little improvement for the complex models. Only the Crossa Raynaud formula approximated generally accepted...

Integration of microbial and chemical controls against codling moth, Cydia pomonella (L.) : laboratory and field evaluation

Creator:: Bajwa, Waheed Ibrahim
Abstract:: The feasibility of managing codling moth, Cydia pomonella (L.), with mixtures of Bacillus thuringiensis-based microbial and selected chemical insecticides was studied under laboratory and field conditions. Joint actions (synergism, additivity and antagonism) of these mixtures were determined for both egg and larval stages. Higher rates of microbial control agents (MCAs),...
