Adult western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), were most abundant on flower clusters of apple, Malus × domestica Borkhausen, from king bloom to full bloom. Low numbers of thrips remained on the clusters after petal fall as fruit enlarged. Thrips larvae peaked in numbers after densities of adults had peaked, usually by petal fall. Two staining proce...

BACKGROUND Some neotropical, fleshy-fruited plants have fruits structurally similar to paleotropical fruits dispersed by megafauna (mammals > 10(3) kg), yet these dispersers were extinct in South America 10-15 Kyr BP. Anachronic dispersal systems are best explained by interactions with extinct animals and show impaired dispersal resulting in altered seed dispersal dynamics. METHODOLOGY/PRINCI...

Understanding the critical host plant factors that determine oviposition behavior and survival of boll weevil, Anthonomus grandis grandis Boheman, on cotton, Gossypium hirsutum L., is important for developing successful pest management strategies. However, published information is both conßicting and limited regarding how different cotton fruit sizes affect boll weevil oviposition choices and s...

nitrogen foliar spray is one of the most important components in fertilizing programs for citrus in iran, as it can reduce nitrate leaching. the goal of this research was to determine the most effective concentration of foliar urea application on “thamson navel’’ orange trees, for achieving the highest yield. foliar sprays were carried out, in two stages with total concentrations of 0.4, 0.8 an...

objective: this field experiment was laid out in order to study on effect of nano and bio fertilizers on yield and yield components of tomato (lycopersicone sculentum l.) during the growing seasons 2013- 2014. methods: the experiment was laid out in a factorial based on randomized block design with three replications. treatments were k nanofertilizer in five levels such as (0, 100, 200, 300 and...

physical properties are often required for designing post harvest handling and processing equipment for agricultural products. persimmon (khormandy cultivar) is rich in vitamin a, calcium, potassium, tannic acid and antioxidant phenolic compounds. in this study changes in the physical properties of persimmon fruit during storage were studied. properties such as fruit dimensions, mass, geometric...

A study was conducted at Mahailluppallama, in the Low country Dry zone (DL1b) of Sri Lanka, during Maha (2008/2009) to determine the fertilizer requirement of Okra when planted at closer spacings. Three (03) fertilizer levels (T1DOA recommendation/ plant, 2 DOA recommendation/ unit area and T31 1⁄2 times DOA recommendation/ unit area) were tested using Okra varieties Haritha and Green Tender (F...

as a first step towards mechanization related to any product, including date fruit, it is necessary to have comprehensive information about the product. physical and mechanical properties are needed for the design of post harvest machinery and equipment. the objective of this study was to determine and compare some physical properties such as dimension, mass and volume, particulate density, pit...

The present study aims to assess the effect of Thiobacillus and sulfur on morphological and biochemical properties of medicinal pumpkinproperties under deficit irrigation based on a split-plot design. For this purpose, water stress was applied as a main factor in three levels (control, no irrigation in flowering stage, no irrigation in fruiting), and Thiobacillus and sulfur fertilizers as sub-p...

Plant hormone keeps a significant role to enlarge the fruit size and quality development. Fruit growers have a lot of interest in making fruit enlargement and shorten maturity to harvest fruit earlier and to make it marketable soon. Gibberellic Acid (GA3) and bark stress play a significant role in fruit enlargement and development. Bilimbi fruit was used in this experiment. The flower bud were ...
