The interaction between legumes and rhizobia has been well studied in the context of a mutualistic, nitrogen-fixing symbiosis. The fitness of legumes, including important agricultural crops, is enhanced by the plants' ability to develop symbiotic associations with certain soil bacteria that fix atmospheric nitrogen into a utilizable form, namely, ammonia, via a chemical reaction that only bacte...

Agricultural yields are often limited by nitrogen (N) availability, especially in countries of the developing world, whereas industrialized nations application chemical N fertilizers has reached unsustainable levels that have resulted severe environmental consequences. Finding alternatives to inorganic is critical for sustainable and secure food production. Although gaseous (N2) abundant atmosp...

Cropping pattern in the Himalayan region of India has undergone a significant change in the recent past. Introduction of horticultural crops such as vegetables, fruits and flowers has led to more intensive agriculture. Such a change, resulting in higher incomes and improvements of the overall living conditions has, however, been accompanied with increased income risk. This emphasizes the need f...

in order to study the effects of intercropping on yield of black cumin in intercropping with chickpea and bean, an experiment was conducted in a complete randomized block design with four replications. crops were planted as pure stands and intercrops in three arrangements: a) alternating rows of a field crop and a medicinal plant, b) two rows of field crops and one row of medicinal plant, c) al...

Pharmaceutical crops is an ambiguous term used by biologists and chemists for different categories of plants. This review focuses on the definition and scope of pharmaceutical crops. We define pharmaceutical crops as those cultivated species that are used for extraction or preparation of therapeutic substances such as active pharmaceutical ingredients (APIs), excipients used in pharmaceutical f...

Legumes are characterized as keeping stable nutrient supply under nutrient-limited conditions. However, few studies examined the legumes' stoichiometric advantages over other plants across various taxa in natural ecosystems. We explored differences in nitrogen (N) and phosphorus (P) stoichiometry of different tissue types (leaf, stem, and root) between N2-fixing legume shrubs and non-N2-fixing ...

Symbiotic associations of bean plants (Phaseolus vulgaris L. cv. Blue Lake) and Rhizobium phaseoli strain 127K17 were treated with the Hill reaction inhibitor bentazon (3-isopropyl-1 H-2,1,3-benzothiadiazin-4-(3H)-one-2,2-dioxide). Plants receiving foliar and root treatments of 1.8 kilograms per hectare bentazon were assayed at 6 hour intervals for N(2)-fixing capacity by measuring C(2)H(2)-dep...
