A field experiment and a laboratory experiment were conducted in 2011 to determine the effect of intensity of defoliation on yield of maize (Zea mays). The field experiment included seven defoliation intensities (0, 2, 4, 6, 8, 10 and whole leaves per plant) from top to bottom leaves. Seeds of the field experiment were used for the laboratory experiment. In the laboratory experiment, germinatio...
Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...
In India, several species of Meloidogyne are reported on a variety of vegetables, cereals, pulses and ornamental plants. Root knot disease caused by M.incognita is a matter of great concern because this species affects several economically important crop plants. Okra is a very important crop by nutrition and health wise. In the present study the application of various parts of neem (seeds, leav...
Cotton is an important crop in the world and is a major source of oil for human consumption and cotton meal for livestock. Cottonseed nutrition (seed composition: protein, oil, and minerals) determines the quality of seeds. Therefore, maintaining optimum levels of cottonseed nutrition is critical. Physiological and genetic mechanisms controlling the levels of these constituents in cottonseed ar...

the present study was conducted to evaluate the effects of these two factors as well as their interaction on seed germination of eucalyptus (e. camaldulensis). a factorial experiment based on a completely randomized design with three replications was used. five salinity levels including 0, 50, 100, 150, 200 mm sodium chloride were tested on seed collected at top, middle and bottom of the tree. ...
To evaluate the yield and nitrate concentration in five Iranian spinach landraces, a study was conducted in 2011 using a randomized complete block design with four replications at Isfahan Agricultural and Natural Resources Research Station. In this field experiment, the evaluated landraces included spiny seed Varamin, Varamin leafy, Shahreza, Najaf Abad and Kashan. Varamin spiny seed landrace w...
A study of the after-ripening of ‘egusi’ melon [Citrullus lanatus (Thunb.) Matsun and Nakai] fruits was undertaken at the Teaching and Research farm of the University of Agriculture Makurdi in the wet and dry season productions of 2005 and 2007. The aim was to monitor its effects on seed quality. Fruits were harvested at two leaf colour stages [i.e. when leaves started turning yellow (LTY), and...
