In the present study, different microalgae were isolated from wastewater environment and evaluated for higher growth lipid accumulation. The adaptability of all tested carbon source with supplementation sodium bicarbonate in BG-11 N + medium. Further based on uptake rate behavior, microalgal strains selected biofuel feedstock. During parameters isolates screened after various sources, which strain Scenedesmus sp. BHU1 was found highly effective among all. efficacy under (4–20 mM)...

Abstract Damask rose ( Rosa damascena Mill.) is a high-value aromatic plant species belonging to the family Rosaceae. It being cultivated throughout world for essential oil production. Besides its higher demand in and cosmetic industry, obtained has many pharmacological cytotoxic activities. The primary concern of growers with available varieties damask short flowering duration, low content unstable yield. Thus, there requirement developing new stable flower yield content. present study...

The phytotoxicity due to nickel (Ni) and its accumulation in castor (Ricinus communis L.) plant of Euphorbiaceae family resulting from addition low very high levels a swell-shrink clayey soil (Haplustert) was studied pot culture experiment. Nine Ni (0, 10, 40, 80, 120, 160, 180, 200, 250 mg kg(-1) soil) were applied. Crop harvested at 45 days after sowing. At the higher levels, beyond 200 soil, reduced growth symptom recorded. concentration parts increased with increasing dose applied Ni....

The global population growth has led to a higher demand for food production, necessitating improvements in agricultural productivity. However, abiotic and biotic stresses pose significant challenges, reducing crop yields impacting economic social welfare. Drought, particular, severely constrains agriculture, resulting unproductive soil, reduced farmland, jeopardized security. Recently, the role of cyanobacteria from soil biocrusts rehabilitating degraded land gained attention due their...

Abstract German chamomile is an important medicinal and aromatic herb known for its blue essential oil. It lacks studies on anthesis, breeding systems floral development with their impact the Therefore, study investigated divided it into six reproductive stages (RS-1 to RS-6). The first four (5–6 days long) were identified as enlargement differentiation, followed by fifth stage (10 of three anthesis flushes, i.e., anther dehiscence, ray disc florets' style branches flush. Anther dehiscence...

The present investigation was carried out to study the effect of various levels dissolved oxygen (DO) on reactive species (ROS) and cryocapacitation-like changes in bull sperm. Egg yolk-Tris-glycerol (EYTG) extender split into four subextenders; viz., Extender I (control; no flushing with liquid nitrogen (LN2 )), II, III IV were flushed LN2 for 40, 16 8 min, respectively. DO standardized 11.7, 2, 4 ppm, respectively, control (Extender I), IV. Ejaculates mass motility ≥ 3+ divided group...

Interestingly more than 50% of the world’s area is rainfed and approximately 80% maize cultivated under condition where selection cultivar management nitrogen have major impact on production. The aim this study was to evaluate growth, phenology, yield quality parameters as influenced by variety scheduling condition. For this, a field experiment having two factors laid out in factorial randomised block design replicated three times. first factor variety, i.e., V1 (JM 216) V2 218), second six...

Among the fungal diseases, sheath blight, caused by multinucleate Rhizoctoniasolani Kuhn (teleomorph: Thanatephorus cucumeris Donk), a ubiquitous pathogen, is an important disease of rice ranking only after blast and often rivalling it. The potential losses due to blight alone in India has been up 51.3%. In this study attempt was made investigate antifungal efficacy botanicals viz., neem (Azadirachtaindica), tulsi (Ocimum sanctum), garlic (Allium sativum), onion cepa), ginger...
