Effects of halo and phytohormone seed priming on germination and seedling growth of maize under different duration of accelerated ageing treatment

  Seed ageing is a main problem of seed storage. Unsuitable storage conditions with high moisture and temperature increases seed ageing. In fact, seed ageing results in the decrease of seed quality. Seed priming is known as a seed enhancement treatment which could improve seed germination and germination synchrony in many of crops. In this experiment we investigated effects of seed ageing, application of...

Relationship between coleoptile and mesocotyl elongation of upland rice (Oryza sativa L.) seedlings under submergence and soil-sand culture

  In rice, the coleoptile and mesocotyl are two morphologically important structures for seedling emergence. After germination, coleoptile and or mesocotyl elongation projects the seedling tip out of the soil and water in which it is planted, allowing the leaves to make contact with the atmosphere thus enabling the seedling to develop into a normal rice plant. Rice genotypes with inherently longer...

Moisture desorption isotherms of Lavandula officinalis L. leaves at three temperatures

  Lavander has been used as a medicinal and aromatic plant and to treat several diseases. Knowledge of moisture desorption isotherms is useful in food dehydration and drying. Moisture equilibrium data of Lavandula officinalis L. leaves were determined by using the gravimetric static method with water activity ranging from 11 to 85% and three temperatures of 30, 40 and 50°C. Five mathematical...

Radio frequency identification (RFID) with mobile-grid based framework for farmland irrigation facility management

  The farmland irrigation system is the lifeblood for the agriculture; due to the fact that the farmland irrigation facilities in Taiwan cover a wide range of area, the traditional Web-based system cannot appropriately meet the dynamic service requirements in the field, and their resource services could not be fully shared and reused. Therefore, in response to the distributed environmental requirements of the...

The effects of working parameters and tillage quality on rotary tiller specific work requirement

  The aim of this paper was to analyze the influence of rotary tiller rotor rotation direction on specific work requirement (SWPTO). The SWPTO was calculated by measuring the PTO (power take-off) torque, PTO speed, working speed and depth, as well as the working width. The tillage quality was determined by the bulk density and soil structure. Reverse rotor rotation direction concept is characterized by...

Comparison of growth performance and genetic diversity of pearl oyster (Pinctada martensii) families in a breeding program

In May of 2009, 28 full-sib families were established by selecting mature breeders in the third generation selected line. Growth performances of the families were compared on the basis of shell height and shell length at juvenile and adult stages. Four families were randomly sampled from the 28 families and their genetic variation was evaluated by using seven microsatellite markers. Significant differences in mean shell...

An analysis of the effect of agricultural extension methods on the utilization of agricultural supports: The case of Erzurum Province in Turkey

  To determine the effect of agricultural extension methods on the utilization of agricultural supports, a survey was conducted with 169 farmers in 7 counties, which were considered to represent Erzurum Province in terms of social, economic and cultural aspects. The survey data was analyzed in LIMPED software by using “crosstab” method and Logistic regression analysis. According to the results of...

Hydrochemical investigation of groundwater contamination in an Urban Area of Beijing aquifer: Impact of irrigation with industrial waste water

  Groundwater quality in Beijing, China was evaluated by measuring the quantities of major and minor elements, temperature, pH, total dissolved solids (TDS), and electrical conductivity (EC). Most samples contained high concentrations of NO3– (5.13 to 164.0 mg/L), which is a serious water quality issue. This NO3– originates from the soil surface and enters the groundwater by infiltration....

Endosulfan induced alterations in physiological responses in Lycopersicum esculentum seeds during germination

  The impact of endosulfan (an organochlorine insecticide), at four concentrations (0.015, 0.03, 0.045 g/L and its recommended field rate 0.06 g/L) on some morphological and biochemical parameters was investigated during the germination process of tomato seeds. The seeds germinating in presence of endosulfan had less and later emergence than the control seeds; the insecticide caused a...

Effects of foliar application of zinc on physiological indices and yield of three spinach cultivars in Bojnourd, Iran

    Spinach (Spinaceae oleraceae L.) is one of the most enriched leaf vegetable used by people in the globe. Inadequate micronutrients especially zinc in most Iranian soils have formed a major constraint to spinach production. Therefore, a study was conducted in 2008 growing season in Kohnekan region of Bojnourd to investigate the effects of foliar application of zinc on physiological indices and...
