Biomass And Carbon Stock Estimation In Woody Grass (Dendrocalamus Strictus L.) In Doon Valley, India, V. Subbulakshmi, Rajesh Kaushal, J. M. S. Tomar, N. M. Alam, J. Jayparkash, Harsh Mehta, A. K. Gupta, A. C. Rathore, O. P. Chaturvedi, P. K. Mishra

IGC Proceedings (1997-2023)

Bamboos commonly kown as woody grass are one of the most important species particularly in Asia, where it is frequently considered as the ―timber of the poor‖ (Rao et al., 1985). With about 23 genera and 136 species, India is the second largest reservoir of bamboos, next only to China (SFR, 2013 and Nath et al., 2009). Bamboos occur extensively in the managed ecosystems of India—both as plantations (and in agroforestry (scattered clumps, hedgerows on farm boundaries etc.

Dendrocalamus strictus L. is most commonly found bamboo in India. It is widely distributed in dry deciduous forests and grows rapidly …

Photosynthesis And Biomass Studies In Lasiurus Sindicus Of Chandan Grassland In Thar Desert, P. Raja, Maharaj Singh, Nilendu Singh, Nawalesh Kumar Sinha

IGC Proceedings (1997-2023)

Grasslands comprise about one third of the world’s area of natural vegetation (Adams et al., 1990). Uncertainties prevail in the arid ecosystem with reference to carbon balance and fluxes which are primarily attributed to the sensitivity of grasslands to variation in annual precipitation, temperature and other regulating mechanisms of eco-physiological processes (Flanagan et al., 2002). It is therefore necessary to study radiation and water use efficiency of Lasiurus sindicus which is a predominant grass species in Chandan grassland of Thar desert to understand and evaluate its growth in relation to variation in climate. Also, it is pertinent to resolve …

Realising The Potential Of Youth In The Development Of Sustainable Grasslands, J. C. Bidogeza, Ralph Von Kaufmann

IGC Proceedings (1997-2023)

The declining interest of youth worldwide to remain in rural areas and pursue careers in agriculture and grasslands is a threat to all human welfare. Ways and means must be found to redress the decreasing interest of youths in grassland development. Ironically there is a lot of untapped potential for rewarding careers but the youths do not have the skills needed to exploit it. This cannot be corrected by providing occasional and piecemeal training opportunities. The perilous consequences of allowing the rangelands to degenerate are sufficiently serious to warrant a comprehensive approach to developing the wide range of skills needed …

Biomass Of Grasses And Other Herbaceous Plants For Bioenergy Use, Žydrė Kadžiulienė, Lina Šarūnaitė, Vita Tilvikienė, Jonas Šlepetys, Zenonas Dabkevičius

IGC Proceedings (1997-2023)

Biomass supply for different uses, especially for bioenergy production, is becoming increasingly important. Independently of the purposes of biomass use, high yields per unit area and best possible quality need to be achieved. As a result, the selection of appropriate plant species is an important aspect. Cocksfoot (Dactylis glomerata L.), tall fescue (Festuca arundinacea Schreb.) and reed canary grass (Phalaris arundinacea L.) were investigated on a light loam (Cambisol) with a view to assessing the impact of nitrogen (N) and harvest time on biomass yield used for biogas. The biomass yield was influenced by cutting …

Forage From Trees And Grasses Of Silvipasture System In Degraded Land Of Semiarid India, R. V. Kumar, Harsh Vardhan Singh, Sunil Kumar, Ajoy K. Roy, P. K. Ghosh

IGC Proceedings (1997-2023)

Rainfed agro-ecosystem has a distinct place in Indian Agriculture, occupying 67% of the cultivated area and supporting 65% of the livestock population (Venkateswarlu, 2005). The silvipasture systems involving suitable multi-purpose trees specially fodder trees and range grass species provide resilience by ensuring continued and multiple outputs such as, forage, fuelwood, fodder, fibre and industrial raw material, besides other positive environmental effects. Incorporation of fodder trees with grasses is perceived as a climate change-resilient cropping system for farmers linking climate change mitigation with adaptation (Mbow et al., 2014). The synergies of tree-grass association need to be explored and exploited by …

Palsaniya, R. K. Tewari, Ramesh Singh, Rupali Tiwwari, Madhulika Srivastava, Mahendra Singh, A. R. Uthappa, P. Rai

IGC Proceedings (1997-2023)

India’s economy is agro-based and about 69% of the total population depends on it for their livelihood (GoI, 2013). Livestock is the integral component of Indian agriculture since time immemorial. Its contribution to national economy through milk, meat, wool as well as farmyard manure is enormous. India has the largest number of livestock, representing over 17% of the world. Among four important species of livestock, cattle represent over 43% of the population followed by buffaloes (19%), goats (26%) and sheep (10%). The share of livestock reared is highest in marginal followed by small and semi-medium land holders implying that marginal …

Modelling The Effects Of Climatic Factors On The Biomass And Rodent Distribution In A Tibetan Grassland Region In China, Quanzhen Wang, Maolin Xia, Bai-Song, Xi-Rao-Zhuo-Ma, Ba-Sang, Jiang- Cuo, Zha-Dui, Jin-Mei, Ze-Duo, Surong Li, Zha-Xi, Yang-Ba, Jia-Yang, Dan-Pei, Jian Cui, Jimin Cheng

IGC Proceedings (1997-2023)

To identify the main climatic factors from 2007 to 2009 that influence biomass and rodent distribution, 576 fixed sample plots within 81 million km² of different climatic grassland in Tibet were monitored. The aboveground biomass, the total burrows, the active burrows, the burrow index, and the rodent density in the plots were measured yearly in October. The monthly precipitation and the average temperatures from April to November were obtained for four successive years (2006-2009). Correlative and modelling analyses between the aboveground biomass, the rodent density, and the climatic factors were performed. The results showed that biomass and rodent density …

IGC Proceedings (1997-2023)

The main objective of this study is to estimate pasture biomass changes in Mongolia using the simulation model CENTURY. For the study framework we used the fenced pasture biomass data from 1960’s to 2008, over 60 meteorological stations and simulation data of the carbon, nitrogen, aboveground and belowground biomass, potential evapotranspiration, evaporation, transpiration and precipitation data across these grasslands. The simulated climatic and other parameters were estimated meteorological station based and their differences between 2 time periods were calculated. With purpose to make comparison of the present situation to the future situation used Climate Change Scenarios under A2, A1B and …

Effects Of Enclosure On Biomass, Carbon, Nutrient Storage And Allocation For Seriphidium Transiliense In A Sagebrush Desert Grassland, Zheng Wei

IGC Proceedings (1997-2023)

We hypothesized that Seriphidium transiliense in a sagebrush desert grassland could improve the storage of biomass carbon and nutrient after 3 years of enclosure. Also, we expect distinctive allocation strategies of nutrient, carbon and biomass partitioning into root (R), root crown (RC), reproductive shoot (RS) and vegetative shoot (VS) plant characteristics or modules. Therefore, the storage and allocation pattern of biomass, carbon and nutrients (N, P, K, Ca and Mg) in different modules were monitored during September and October, from 2009 to 2011. The results showed that the P content of root, the N content of reproductive shoot, the Ca …

Does The Short-Term Grazing Affect Functional Group And Plant Species Diversity Of Alpine Meadow In The Tibetan Plateau?, Fuhong Miao, Zhenggang Guo, Yuying Shen

IGC Proceedings (1997-2023)

Grazing affects the physiological and ecological characteristics of the plant community, through livestock intake and trampling (Georgiadis et al. 1989). Previous studies in the Qinghai-Tibetan Plateau have shown that the composition and structure of alpine meadow plant communities respond to grazing (Niu et al. 2010). However, the changes to functional groups and species diversity caused by grazing are not well documented, especially with regards to short term effects (McLaren 2008). In this study, different grazing rates were used to determine the relationship between functional groups, community diversity and yak stocking rates. The objective of this study was to …

The Effect Of Exclosures On Poa Bulbosa And Determination Of Predation: A Case Study In The Nodoushan Rangelands, Central Steppe Of Iran, Anahita Rashtian

IGC Proceedings (1997-2023)

In order to undertake investigations leading to reclamation management for rangelands, information is needed on the effect of exclosures on the production and morphology of key species such as Poa bulbosa. This paper describes a comparison of some morphological and ecological characteristics of P. bulbosa when subjected to grazing or protected long-term with exclosures. The investigation was undertaken on the Nodoushan rangelands of Yazd Province, Iran.
