In the present work genetic diversity in 23 chilli genotypes was analyzed by RAPD markers generated by 13 random primers out of which 9 were polymorphic. The amplification profile of these 9 primers consisted of 63 fragments of size ranging from 391 bp to 2754 bp of which 35 were monomorphic and 28 were polymorphic with 44.4 % polymorphism. The number of bands generated by each primer varied from 5 (OPB-10) to 9 (OPB-01 and OPB-15) with an average of 7 fragments per primer. The percentage of polymorphic bands with different primers ranged from 14.29 to 66.67 %. The similarity coefficients detected by RAPD ranged from 0.42 to 0.97 which revealed existence of limited genetic variation among chili genotypes. The consensus tree constructed showed three major clusters. First cluster comprise of 13 genotypes, second cluster of 7 genotypes and third cluster of 3 genotypes. The RAPD technology proved useful in describing genetic diversity among chilli genotypes. ····· 1036192611

Iron and aluminum phosphates predominate under acidic condition. The low availability of P to plants is because the vast majority of soil P is found in insoluble forms .Thus, the release of insoluble and fixed forms of phosphorus is an important aspect of increasing soil phosphorus availability.Plant root-associated phosphate solubilizing bacteria (PSB) have been considered as one of the possible alternatives for inorganic phosphate fertilizers for promoting plant growth and yield. Considering the above stated role of bacteria for P solubilization in acid soils of Bangladesh, the present work was therefore undertaken with the following objectives: To isolate some rhizoplane bacteria from the roots of rice plants and screening potential phosphate solubilizing bacteria (PBS) from the isolates To quantify P solubilization from tricalcium phosphate by potential PSB in broth culture conditions and To see the performances of potential PSB on growth and nutrients content of rice in acidic soil of Bangladesh. ····· 1036192590

Identification of DNA markers linked to these diseases is a prerequisite for accelerating resistance breeding through marker-assisted selection (MAS). The objectives of the present study were to investigate the inheritance pattern of septoria leaf spot resistance and identify molecular markers linked to septoria leaf spot and late blight resistance in tomato. The inheritance of resistance to septoria leaf spot was based on a single dominant gene. Transgressive segregation for resistance and susceptibility to late blight was also observed. Out of the 34 RAPD polymorphic markers 11 primers (32.35%) were polymorphic between resistant and susceptible bulks of septoria leaf spot and 16 (47%) produced polymorphic bands between resistant and susceptible bulks of late blight lines. ····· 1036192574
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Chickpea (Cicer arietinum L.) is the third most important food legume worldwide. Legumes have played a crucial role in agricultural production due to their capacity to fix nitrogen. Symbiotic nitrogen fixation between rhizobia and legumes requires genetic compatibility between host and root nodule bacteria to establish an effective nodule. Variability for nodulation in the host cultivars is significantly high. The number of host genes controlling nodulation in legumes is likely to be quite high. With so many genes involved, it is not really surprising that we continue to identify cultivars defective in some trait limiting nodulation or nitrogen fixation. The non-nodulating trait (Nod-) in chickpea was first observed in 1985 in the cultivar ICC 435, which was found to be controlled by a single recessive gene. The non-nodulating and the low nodulating selections are of interest for studies of the physiology and genetics of nodulation and nitrogen fixation, as well as providing a reference base in biological nitrogen fixation (BNF) quantification studies. ····· 1036192564

The livelihood system encompasses concepts of the agricultural use value of the land and how land use itself is situated in broader social relationships. Institutionalized practices, such as sharecropping, explain how management aspects of the land enter productive relationships among villagers. The dwelling aspect, being a broader part of the relations and commitments of the villagers to their landscape, explains land users perception and values of the land. The land tenure systems have secured local people s user rights to land. Nonetheless, the tenure systems are poor in promoting farm integrity, long-term security and transfers of land resources to more competitive and productive farmers. Future approaches that aim to promote good land and agricultural management practices should consider these broader issues simultaneously. ····· 1036192555

Presently, India with a growth rate of more than eight percent is competing with most of the developed countries of the world. Agriculture is one of the important sectors of economic development. Its production capacity enhances through capital formation. Sustainable agriculture refers to the ability of a farm to produce sufficient food, without causing irreversible damage to ecosystem health. The issue is two-fold, i.e., biophysical and socioeconomic. The use of new technologies along with government policy has changed the pattern of agricultural production. The excessive use of chemicals along with subsidies on the one hand supports the agricultural output but on the other hand its excessive use results into depletion of soil and water condition. As a result, the cost of production increases. The increasing cost and decreasing agricultural growth rate puts a question mark on the sustainability of agriculture as well as on non agricultural sectors. ····· 1036192506

The area under severity of soil salinity in both coastal and inland ecosystems across the globe is increasing constantly. Salinity affects approximately 7 per cent of total global land area. Among the food crops, rice is one of the most suitable crops for these coastal areas because of its ability to flourish in flooded soils and leaching salts out of the soil. Hence this investigation in rice (Oryza sativa L.) was carried out to study the genetics of salinity tolerance. Based on the diversity analysis 14 parents were selected and for crossing. The combining ability analysis revealed that the importance of non-additive gene action in controlling all the salinity tolerant and yield contributing traits. The characters viz., chlorophyll a/b ratio and shoot Na/K ratio had negative significant association and chlorophyll stability index, catalase and peroxidase were positive significant association with the grain yield.

Softwood and hardwood barks represent waste products with unique chemical properties including significant quantities of tannins that have an affinity for scavenging and immobilizing these pollutants. This book provides an analysis of the literature that has been undertaken in relation to the reactions between heavy metals and barks and provides a fundamental approach to modeling and characterizing heavy metal immobilization in bark.

The capacity of the crop for its biological nitrogen fixation and high seed protein content increases its agricultural demand and economical value. But low yield and poor seed quality often encounters mungbean cultivation. Although, mungbean plant produces a large amount of flowers but most of them abscise rather than develop into mature pods which reduces yield. Moreover, lack of proper nutrient management especially nitrogen and weather damage may often causes deterioration of the quality of seeds resulting poor stand establishment of successive crop that eventually gives poor seed yield. This book presents the various physiological aspects of flowering pattern, flower abscission, growth rate, rate and duration of seed filling, proper nitrogen management, and impact of seed priming, simulated rainfall effects on seed quality of mungbean.

Among several factors, feed shortage both in terms of quantity and quality is a major problem hindering the development of livestock industry in Ethiopia. In the highlands of Ethiopia, the feed requirement to maintain the livestock population is estimated to be 55 million tones of dry matter (DM), which is much larger than the 40 million tones of DM estimated to be produced annually (Betre, 1999). This indicates an annual livestock feed deficit of about 22%. The factors contributing to the deficit in DM supply are fast deterioration of the natural grazing land associated with a rise in crop cultivation, over stocking /over grazing and recurrent droughts. This situation requires seeking better ways for utilization of alternative livestock feed resources from agricultural and industrial by-products that are relatively cheaper sources for supplementation of animals on fibrous basal feeds. ····· 1036192284
