Abstract

The present study was conducted to investigate the effect of age (one and two year old) growing condition (intermittent misting and no misting) and seasons summer, monsoon, autumn and spring) on ischolar_maining behaviour of culm cuttings of Bambusa balcooa. The findings indicated that two year old culm cuttings in the intermittent misting condition gave best response.The findings also indicated that ischolar_maining and sprouting per cent of culm cuttings planted in different season showed response as Spring (March)>Summer (June) > Monsoon (August) > Autumn (October).

Abstract

The paper reports for the first time ischolar_maining in Adina cordifolia using macropropagation technique. Two different types of cuttings viz. branch cuttings (hardwood, semihardwood and softwood) and mono nodal leafy softwood cuttings, prepared from epicormic shoots were treated with 4000 and 6000 ppm IBA for 10 seconds. The results revealed that hardwood and semi-hardwood cuttings failed to ischolar_main even with the application of IBA. Softwood cuttings prepared from terminal portion of the lateral branches showed 15 to 18 per cent ischolar_maining with the application of IBA. Mono nodal leafy softwood cuttings resulted in 62.5 per cent ischolar_maining with the application of 4000 ppm IBA. The ischolar_maining increased to 75 per cent when the concentration was increased to 6000 ppm IBA. Other ischolar_maining and sprouting parameters also showed similar pattern.

Abstract

Fourteen species of bamboo were evaluated for nutritional and fodder quality parameters through metroglyph analysis. On the basis of morphological and qualitative variation in bamboo species scatter diagram was prepared. An examination of the scatter diagram revealed that six groups could be distinguished on the basis of morphological variation. All the species were divided into six groups. Maximum number of species was comprised in group-II (5 species) followed by group-V (4 species) and group-IV (2). From metroglyph and index score analysis, long range of index score was from 16 to 22 observed which itself indicated the large amount of variation in the bamboo species studied.

Abstract

Bamboos are fastest growing plants extensively used for variety of purposes; among them are stock fodder, erosion control and shelter. As a fodder species, bamboos are not potentially investigated and research lacks the qualitative approach of nutritive value found in different species of bamboo. Therefore, work on fodder quality was carried out with fourteen species of bamboo and evaluated for genetic divergence, nutritional and forage quality parameters. Based on divergence analysis of pooled data, the 14 species of bamboo were grouped into four clusters. Cluster I had maximum number of species (7), Cluster III had four species whereas Cluster II and Cluster IV had maximum of (2) and (1) species respectively. Maximum intra-cluster distance was in Cluster II and maximum inter-cluster distance was between cluster II and IV. Correlation analysis revealed that leaf:stem ratio, biomass, crude protein content, dry matter digestibility had major contribution in determining the nutritive potential of green and dry forage yield. Bamboos biomass and nutrient distribution has enormous potential to become a quality fodder for livestock animals. Therefore, bamboo may be planted in a marginal land which makes the soil fertile and produced evergreen biomass round the year.

Abstract

Bamboos serve as multipurpose forest grass species. The success of bamboo as a commercially important forage species depends on the identification of genetically divergent materials of the plant and developing superior planting stock for the farmers. The phylogeny plays a crucial role in the evolution of species and superior germplasm. Twentytwo species of bamboo were evaluated for genetic diversity characterization through SDS-PAGE analysis. Based on electrophoretic pattern, banding pattern was established for 22 species. Also, on genetic diversity analysis, 22 species of bamboo were grouped into four clusters. Cluster IIBb had maximum number of species (9), cluster IIBa and cluster IIAb had four species each, whereas, Cluster IIAa and cluster IA had maximum of two and three species respectively. UPGMA (Unweighed Paired Group Mean Cluster Analysis) inferred that among Bambusa genera; species B. bambusa, B. multiplex, B. vulgaris, B. balcooa, B. tulda, B. nutans, B. polymorpha, B. nutans and B. pallida and among Dendrocalamus species D. hamiltonii, D. giganteus, D. membraneceous and D. longispathus were genetically similar having Jaccard's similarity coefficient ranged from 0.80-1.00.

Abstract

An experiment to evaluate the performance of different varieties of soybean (Glycine max L. Merrill) under two year poplar based agroforestry system was conducted during kharif season in tarai region of Uttarakhand. Four varieties of soybean viz., PS 1042, PS 1225, PS 1347 and PS 1024 of soybean were grown under poplus, and as sole crop. Germination count/m² and plant height was not significantly influenced by growth conditions. Growing condition significantly influenced primary branches and number of pods per plant of soybean however; grains per pod, pod length per plant and hundred grains weight (g) were insignificant. Among the varieties, all the yield attributes were higher in PS 1225 except hundred grains weight which was higher in PS 1042. Grain and straw yield were found to be higher in open system (sole soybean) as compared to under shade of poplar showing reduction of 3.94 and 9.86 per cent, respectively. Soybean variety PS 1225 recorded highest grain yield (2996 kg/ha) as compared to all other varieties under-storey poplar. However, maximum harvest index was observed in PS 1347 (44.22 %). It can be concluded that soybean crop can be successfully grown under poplar during second year of plantation.
