Abstract: A twelve-week study was undergone to identify selective effects of Mucuna on companion crop plant and to screen Mucuna for capacity to suppress weeds. A 10% (v/w) contamination with Nigerian Bonny light crude oil was simulated for stress tolerance assessment. Mucuna pruriens supported revegetation, soil and water conservation and also contains potentially toxic BTEX and PAHs that are not phytotoxic to itself but suppressed the growth of Sphenostylis stenocarpa and inhibited the growth of weeds. The detrimental infl…

Abstract: Downy mildew or green ear disease of pearl millet caused by Sclerospora graminicola is the most destructive disease. Affected plants produce green ear with various types of proliferations and malformation of the panicle. Deranged physiology of susceptible and resistant varieties is governed by genetic base, pathogen virulence and induced resistance. Phenolic compounds have been noticed most influential secondary products in determination of resistance in pearl millet plants. In relation to this, activities of polyp…

Abstract: Anti-inflammatory activity of extract of Lantana camara, Linn and its fractions was investigated using stabilization of red blood cell membrane lysing technique. Phytochemically, whole plant extract (WPE) and ethanol fraction (EF) gave positive reactions for the presence of saponins, tannins, flavonoids and cardiac glycosides. The ethyl acetate fraction (EAF) gave reactions for the presence of flavonoids while butanol fraction (BF) gave positive test for the presence of saponins. The percentage membrane stability e…

Abstract: An area of plant science that is still unexplored is how leaf area affects crop dry matter production due to aeration of seed in osmoticum. In view of this, an experiment was conducted at Agricultural Research Farm of NWFP Agricultural University, Peshawar, Pakistan in the summer of 2003 and repeated in 2004. The seeds of two mung bean cultivars (NM-92 and NM- 98) were primed, some for 6 h and others for 12 h in using either distilled water (0MPa osmotic potential) or Polyethylene glycol-8000 (PEG) solution having…

Abstract: A field study was conducted at the Teaching and Research Farms of the University of Benin, Benin City, Nigeria in 2007 and 2008 to evaluate the effect of palm oil mill effluent and NPK fertilizer on the performance of Amaranthus cruentus. The trial involved three levels of palm oil mill effluent (0. 5 and 10 t ha-1) and three levels of NPK (0, 150 and 300 kg ha-1) using a factorial arrangement fitted into randomized complete block design and replicated three times. Results revealed that the effluent and NPK fertili…

Abstract: Exogenously applied salicylic acid has been shown to be an essential signal molecule involved in both local defense reactions and induction of systemic resistance response of plants after salt stress. Our study was aimed at evaluating the foliar spray with different levels (0.0, 0.5 and 1.0 mM) of salicylic acid (SA) on broad bean (Vicia faba L) seedlings grown under diluted seawater on growth and some related physiological responses. Seawater irrigation negatively affected growth parameters, free amino acids and K…

Abstract: Physiological responses to salt stress were measured in Chenopodium quinoa, a regionally important halophytic staple crop of Andean South America. In a greenhouse experiment, salt (NaCl) was applied to quinoa varieties, Chipaya and KU-2, and to the model halophyte Thellungiella halophila to assess their relative responses to salt stress. Height and weight data from a seven-week time course demonstrated that both C. quinoa cultivars exhibited greater tolerance to salt stress than the model plant T. halophila in thes…

Abstract: Salt toxicity is one of the major problems in modern agriculture. Plants can employ silicon as a protective agent against stresses and the mechanisms of this process remain unknown. Two Egyptian clover (Trifolium alexandrinum) cultivars differing in salinity tolerance were used (Helaly, salt sensitive and Sarw1, salt tolerant). They were grown in pots filled with normal and saline soil (2000 and 3000 ppm) in the absence or presence of diatomites (0, 1.5, 3 and 4.5 g/kg soil). Results indicated that diatomite signif…

Abstract: Study was conducted to see the changes in ascorbic acid, free amino acids, proline and total phenol content at different stages of infection of wilt disease in chickpea (Cicer arietinum L) roots tissues. The results indicated that total phenol content was significantly higher in root of all the cultivars obtained from sick plot. The level of phenol declined from pre infection (S1) to post infection stage (S2) and further it increased in all the cultivars among six cultivars tested, JG-62 and GG-1 had lower concentr…

Abstract: An experiment was carried out with Black Isabgol (Plantago indica L) an annual herb cultivated recently as a medicinal plant at Directorate of Medicinal and Aromatic Plants Research (DMAPR) in India, aiming on the effect at different stages of growth under the influence of different sowing dates and spacings on growth, seed yield and seed swelling factor as a part of good agricultural practices (GAP). No detail morpho-physiological work has been carried out in this species including yield. Results revealed that gro…

Abstract: The characteristics of symbiotic nitrogen fixation in tropical forest tree species have received little attention but it is well established that mineral N negatively affects symbioses in crop legumes such as soybean and common bean. Nevertheless, ecophysiological mineral nitrogen dynamics in terms of nitrogen xylem transport of native Amazonian legume has been not documented so far. The objective of this study was to evaluate nodulation and amino acid xylem transport of Inga edulis, a tropical Amazonian perennial…

Abstract: Some positive health benefits have currently been attributed to coconut intake. An attempt has been made to determine the fatty acids and phytochemical contents of coconut seed flesh collected from the different parts of Nigeria. The fatty acid composition was determined by gas chromatography while phytochemical content was detected using the polar and non polar solvents. The findings revealed that samples from eastern Nigeria had highest fatty acids (caprylic: 8.60±0.00%; lauric: 41.30±0.14%; palmitic: 13.00±0.14%…

Abstract: Drought stress is the most significant factor that reduces crop yield and is used as a drug. Using materials such as a plant growth regulator (Brassinosteroids) is a practical solution to reduce losses. Brassinosteroids steroidal plant compounds are broad biological activities that are able to increase plant performance through changes in plant metabolism and in protecting them against environmental stress. In a greenhouse study that was carried out in Vocational City Center Arsanjan, the impact of three levels of…

Abstract: Alkaloids, tannins, saponins, steroid, terpenoid, flavonoids, phlobatannin and cardic glycoside distribution in ten medicinal plants belonging to different families were assessed and compared. The medicinal plants investigated were Cleome nutidosperma, Emilia coccinea, Euphorbia heterophylla, Physalis angulata, Richardia bransitensis, Scopania dulcis, Sida acuta, Spigelia anthelmia, Stachytarpheta cayennensis and Tridax procumbens. All the plants were found to contain alkaloids, tannins and flavonoids except for th…

Abstract: The effects of different soil tillage methods on rhizobial nodulation, biomass yield (root, shoot and nodule) and nitrogen content of soybean as a second crop have been investigated. The experiment was conducted as a field trial in Cukurova Region, Turkey in 2008. Six different tillage methods have been studied in this research. These methods were conventional tillage with residue (CTR), conventional tillage with burnt residue (CTBR), reduced tillage with heavy disking (RTHD), reduced tillage with rotary tiller (RT…
