although water deficiency has been seriously taken up as a subject in reducing crop production in arid and semi–arid areas, nevertheless little information has been published regarding its effects on seed quality. to evaluate the effects of irrigation regimes (full irrigation (control), irrigation until flowering stage, irrigation until doughing stage and irrigation until eight-leaf stage) on g...

to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...

Sweet sorghum (Sorghum bicolor (L.) Moench) is a multiple-purpose crop which has been consumed as either food or feed and recently, industrially cultivated for liquid sugar and ethanol production. Biomass and carbohydrate composition of sweet sorghum are considered as important factors for industrial productions. Thus, in this study fresh stalk yield, total sugars, sucrose content and invert su...

Laboratory experiments were conducted to evaluate the allelopathic effects of the water extract of Argemone mexicana L. on the seed germination, plumule length, radicle length, fresh and dry weight in Sorghum (Sorghum bicolor Moench). The allelopathic potentialities of leaf extracts of A.mexicana decreased the seed germination of Sorghum bicolor with raise of extracts concentration. The extract...

Sorghum (Sorghum bicolor (L.) Moench) is the fifth important cereal crop after wheat (Triticum aestivum L.), maize (Zea mays L.), rice (Oryza sativa L.), and barley (Hordeum vulgare L.) in the world. It is cultivated in about 46 million ha with a total production of 62 million t (FAO 1998). Asia and Africa account 86% of the total area under sorghum, but their contribution towards total product...

Sorghum (Sorghum bicolor (L.) Moench) pericarp pigments can affect grain quality. Pigments found in vegetative parts of the plant and in the peduncle and glumes of flowers (12,44) also may indirectly impact sorghum grain quality. Pigments associated with the “purple wound response” accumulate following mechanical injury, insect feeding, or pathogen invasion (22,31). Grain with nonpigmented peri...

The inhibitory activity of aqueous extracts of field-grown sorghum (Sorghum bicolor cv. Bird-a-boo) herbage and roots was quantitatively indexed by three aspects of cumulative cress (Lepidium sativum cv. Curlycress) seed germination: the germination onset; weighted mean rate; and final germination percentage. Extract potency was greatest for herbage collected four weeks after planting but decli...

Sorghum (Sorghum bicolor ( L. ) Moench ) has emerged as a leading candidate for biomass utilization among energy crops due to high yield potential, ease o f culture and wide adaptibility. Previously, enormous diversity present in the germplasm has been manipulated by sorghum breeding programs primarily to produce grain, syrup or forage. Development of sorghums for energy utilization will requir...

Objective: Importance of management of gardens weeds is an issue that unfortunately has less been investigated by weeds researchers of country. One of the most important restrictive agents of cultivated surface and producing crops of Citrus orchards are weeds. Methods: To achieve this purpose, a research was performed in plot of Valencia orange trees of citrus fruits of Dezful in 2013. This pro...

The present investigation was conducted to assess the magnitude of heterosis rabi sorghum (Sorghum bicolor (L.) Moench) developed by crossing four lines and twelve testers (in a line × tester design) produce 48 F1 cross combinations at Sorghum Improvement Project, MPKV., Rahuri, Maharashtra. To identify high-yielding Rabi hybrids, promising hybrids were sorted out based on positive significant ...
