Abstract: An experiment was conducted in a farmer’s field in Ban Muong village, Muang district in Khon Kaen province in 2003. The objective of this study was to investigate the effect of mungbean (Vigna radiata L.) residue and nitrogen rates (0, 30 and 60 kg N ha-1) on growth and yield of direct seeded rice (Oryza sativa L.) in rainfed riceland. The results showed that mungbean residue had no effect on tiller number, leaf area index and total top dry weight of rice in rice-mungbean intercropping or sole rice cropping. Also, mungbean residue had no significant effect on panicle number m-2, spikelets number per panicle, 1,000 grain weight, percentage filled grain, harvest index or grain yield However, mungbean residue tendes to increase rice grain yield over sole rice by 0.33 t ha-1(13 %) with had no nitrogen application. Rice grain yield was significantly affected by nitrogen rates. The highest rice grain yield (2.7 t ha-1) was obtained with a nitrogen rate of 30 kg N ha-1. Nitrogen fertilizer application at a rate of 60 kg N ha-1 decreased grain yield, when compared with 30 kg N ha-1.

Pakistan Journal of Biological Sciences , 2000,
Abstract: The research study was conducted at two locations i.e. Barani Agricultural Research station (Kohat) and Barani Seed Farm (Hangu) to ascertain the biological efficient and economic efficient intercropping system of maize with cowpeas and mungbean. The studies consisted of five intercropping systems (maize sole, cowpeas sole, mungbean sole, maize + cowpeas and maize + mungbean). The results regarding LER showed that maize + cowpeas intercrop average of two locations was 1.29 indicating 29 percent yield advantage which is also biological efficient system. The maize + mungbean indicating 4 percent yield advantage. However, the economic analysis gave a different results which showed that mungbean sole crop gain highest BCR value (return per rupee invested i.e. Rs. 4.82) followed by cowpeas sole crop (Rs. 4.13). It is concluded that apart from biological efficient different economic indices should be computed for comparison and final recommendation for wide spread adoption.

Pakistan Journal of Biological Sciences , 1999,
Abstract: A field experiment was carried out to investigate growth, yield and yield components of cassava and mungbean and land use efficiency, economic returns, and the uptake of soil nutrients (NPK). The results showed that total top dry weights, leaf area indices (LAI), yield and yield components of cassava were not affected by intercropping patterns and did on total top dry weights and leaf area of mungbean. Whilst grain dry weights, and pods per plant of mungbean were affected by cropping patterns but not with grains per pod and 1000-grain weights. Land equivalent ratio and combined economic value were much greater for intercropping patterns than that of the sole crop both cassava and mungbean. Nutrient uptake per hectare of roots, stems, leaves of cassava were unaffected by intercropping patterns but did with that of mungbean due to the differences in plant populations. Total NPK uptake of cassava and mungbean grown together under intercropping patterns was similar to that of sole crop of cassava. However, the margin profit was much greater for intercropping plants than that of the sole crop since market prices were higher and the residues of plant materials of mungbean could be used to improve soil fertility apart from nodules of this legume crop being produced.

Journal of Applied Sciences , 2003,
Abstract: A field experiment was conducted to assess the growth and yield performance of mungbean (Vigna radiata) varieties under various phosphorus and potash levels at Student’s Experimental Farm, Sindh Agriculture University, Tandojam. Four mungbean varieties viz. AEM/25, AEM-6/20, NM-20/21 and AEM-10/2/87 were tested. Most of the agronomic traits of mungbean varieties were significantly influenced by phosphorus and potassium fertilizers except pod number, seed weight per plant and seed index were non-significant. However, 100-100 PK kg ha￣1 showed an increase in the yield of the crop. Thus, it is recommended that the mungbean crop should be fertilized with phosphorus and potassium at the level of 100-100 PK kg ha￣1 for achieving satisfactory seed yield.

Asian Journal of Plant Sciences , 2002,
Abstract: Effect of surface broadcast and band placement of N and P fertilizers was evaluated in cotton-mungbean Intercropping system with respect to yield and crop productivity under field conditions. Response of interplanted crops to both elements varied with their mode of application. Significantly higher crop harvests were recorded from the placement of nutrients than broadcast application. Nutritional choice of both crops was different since cotton preferred N over P whereas reverse was true for mungbean. More over, highest return from cotton-mungbean Intercropping system was obtained with the band placement of fertilizer N along with the cotton and fertilizer P along with the mungbean.

Pakistan Journal of Biological Sciences , 2008,
Abstract: In order to evaluate the ear and forage yield of sweet corn (Zea mays L. var. Saccarata) in pure stand and intercropped with mung bean (Vigna radiata L.), a field experiment was conducted at Varamin region on summer 2006. Experiment was carried out in a split plot design based on randomized complete blocks with 4 replications. Plant density with 3 levels [Low (D1), Mean (D2) and High (D3) respecting 6, 8 and 10 m-2 for sweet corn, cultivar S.C.403 and 10, 20 and 30 m-2 for mung bean cultivar, Partow] was arranged in main plots and 5 mixing ratios [(P1) = 0/100, (P2) = 25/75, (P3) = 50/50, (P4) = 75/25, (P5) = 100/0% for sweet corn/mung bean, respectively] were arranged in subplots. Quantitative attributes such as plant height, sucker numbers, LER, dry matter distribution in different plant organs were measured in sweet corn economical maturity. Furthermore the yield of cannable ear corn and yield components of sweet corn and mung bean were investigated. Results showed that plant density has not any significant effect on evaluated traits, while the effect of mixing ratio was significant (p<0.01). Therefore, the mixing ratio of 75/25 (sweet corn/mung bean) could be introduced as the superior mixing ratio; because of it`s maximum rate of total sweet corn`s biomass, forage yield, yield and yield components of ear corn in intercropping. Regarding to profitability indices of intercropping, the mixing ratio 75/25 (sweet corn/mung bean) in low density (D1P2) which showed the LER = 1.03 and 1.09 for total crop yield before ear harvesting and total forage yield after ear harvest respectively, was better than corn or mung bean monoculture.

Abstract: We have generated and characterized a total of 470,024 genome shotgun sequences covering 100.5 Mb of the mungbean (Vigna radiata (L.) Wilczek) genome using 454 sequencing technology. We identified 1,493 SSR motifs that could be used as potential molecular markers. Among 192 tested primer pairs in 17 mungbean accessions, 60 loci revealed polymorphism with polymorphic information content (PIC) values ranging from 0.0555 to 0.6907 with an average of 0.2594. Majority of microsatellite markers were transferable in Vigna species, whereas transferability rates were only 22.90% and 24.43% in Phaseolus vulgaris and Glycine max, respectively. We also used 16 SSR loci to evaluate phylogenetic relationship of 35 genotypes of the Asian Vigna group. The genome survey sequences were further analyzed to search for gene content. The evidence suggested 1,542 gene fragments have been sequence tagged, that fell within intersected existing gene models and shared sequence homology with other proteins in the database. Furthermore, potential microRNAs that could regulate developmental stages and environmental responses were discovered from this dataset.In this report, we provided evidence of generating remarkable levels of diverse microsatellite markers and gene content from high throughput genome shotgun sequencing of the mungbean genomic DNA. The markers could be used in germplasm analysis, accessing genetic diversity and linkage mapping of mungbean.Mungbean (Vigna radiata (L.) Wilczek) is an important food leguminous crop in Asia, with an annual production of around 3.5 - 4.0 million tons [1]. The crop is grown principally for its protein-rich dry seeds (24% protein) which is a major protein source for people in Asian countries as part of a nutritionally balance diet [2]. It is popularly grown as a component in various cropping systems because of its ability to fix nitrogen in association with soil bacteria, early maturity (ca. 60 days) and relatively drought tolerance. Mungbean belongs

Indian Phytopathology , 2012,
Abstract: The destructive yellow mosaic disease of mungbean (Vigna radiata (L.) Wilczek) was prevented under natural field condition, by clarified aqueous root extract of Boerhaavia diffusa. Treatments were administered weekly, as foliar sprays, at a concentration of 10%, commencing from the seedling stage. Six sprays of B. diffusa root extract were found most effective and considerably delayed symptom appearance, suppressed symptom severity and decreased disease incidence by 80-90%, besides increased nodulation in roots, plant height, primary and secondary branches, pod formation and grain yield. The root extract could be used as possible prophylactic agent against the mungbean yellow mosaic disease in highly susceptible local mungbean varies to avert the severe yield loss.

Asian Journal of Plant Sciences , 2002,
Abstract: The study was undertaken to determine the performance of cotton and mungbean, when grown simultaneously in different geometric proportions and fertilized by various methods. Compared to sole cropping, the yield of interplanted cotton was reduced significantly by increasing the density of recessive component of intercropping system. The reduction in seed cotton yield was accounted to be 30% in 1:1 and 40% in 1:2 cotton-mungbean planting geometry. However, statistically similar seed cotton yield to that of sole cotton was recorded from the system following 2:1 row arrangements of cotton and mungbean. Fertilizer N applied by banding alongside the rows of cotton produced significantly higher seed cotton yield as compared to broadcast applications, whereas, N applied through broadcast method over entire plot led to higher mungbean harvest when compared with the treatment receiving fertilizer N by banding technique. Cotton and mungbean interplanted according to 2:1 row arrangements surfaced as the most compatible system by producing combined yield of 4465 kg ha -1, which was 18.7% higher than monoculture cotton.
