Objective: Germination is one of the most important stages of plants growth that affected by environmental stresses, especially drought and salinity. Methods: In order to study of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The four levels of salinity by NaCl (0, 50, 100, 150 mM) with three replications and five levels of drough...
In addition to seed quantity, study of seed quality of crop in conditions of competition could be profitable for seed procurement from field. For this purpose, produced seeds of four wheat cultivars (Sayson, Alvand, Chamran and Sepahan) in interference with deferent densities of feral rye (0, 20, 40, 60 and 80 plants m-2) were harvested. In laboratory, of each field unit, 50 number of wheat see...
Extended Abstract Introduction: Weeds, as the most important biological stress, reduce the efficiency of water use, waste of food, shading and secretion of toxic substances, leads to a 10 to 100 percent reduction in crop yields. The first step of the weed control understands the biology and life cycle of the weed particularly seed Eco physiological characteristics. Dormancy in weed seeds, incl...
The experiment was conducted at Central Horticultural Experiment Station, ICAR- IIHR, Aiginia, Bhubaneswar, Odisha, India during kharif seasons of 2018 in collaboration with Odisha University Agriculture and Technology, to study the seed germination, days taken reach grafting stage success (percentage) rootstock scion seeds used for grafting. cultivated wild species brinjal tomato were as roots...
Ephedra is a dioecious shrub belongs to the Ephedraceae family. Almost all commercial applications of Ephedra extracts is derived from the ephedrine alkaloids found in the evergreen stems. The purpose of this study was to investigate seed germination in green house condition and total alkaloid and ephedrine amounts measurement. The Ephedra seeds were collected from Bojnoord region and germinate...
A major problem of arid and semi-arid regions is environmental stresses like salinity and drought. To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The experimental treatments included different salinity levels of NaCl (0, 50, 100, 150 mM) and five drought levels by PEG (0, 10%, 15%, 20% and 25%) with three rep...
Traditionally farmers monitor their crops employing senses and experience. However, the human sensory system is inconsistent due to stress, health, age. In this paper, we propose an agronomic application for monitoring growth of Portos tomato seedlings using Kinect 2.0 build a more accurate, cost-effective, portable system. The proposed methodology classifies into four categories: first corresp...
The efficacy of five native botanicals viz., neem, castor, akondo, basok and ata against the seed associated fungi in controlling leaf spot disease black mustard was evaluated. In blotter method, maximum reduction (85.91%) observed seeds treated with (1:1) while neem (1:1), (1:2) castor gave 83.52, 82.59 82.39%, respectively over control. Maximum germination (93%) akondo where supported 92, 92 ...
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...
