Buffel grass (Cenchrus ciliaris L.) is an important perennial grass grown widely in arid and semiarid regions of the world. It is one of the prominent species of the Dichanthium-Cenchrus-Lasiurus grass cover spread over the Peninsular India (Dabadghao and Shankarnarayan, 1973). C. ciliaris is a warm season, C₄ grass well adapted to survive harsh conditions, elevated CO₂ levels and wide range of climates and soil regimes. It is considered an excellent pasture grass as it provides highly nutritious and palatable forage during drought periods. Despite its excellent forage characteristics genetic improvement through conventional breeding methods has been …

Scar Markers Linked With Mode Of Reproduction In Eight Cenchrus Species, Suresh Kumar, Sheena Saxena, M. G. Gupta

IGC Proceedings (1997-2023)

The genus Cenchrus comprises of forage grasses of tropical and sub-tropical regions. Some of the Cenchrus species were introduced into India from Australia, Africa and they are now important component of Dichanthium-Cenchrus-Lasiurus grasslands of India. Eight Cenchrus spp. are available in India but only four (C. ciliaris, C. glaucus, C. pennisetiformis and C. setigerus) species are used in sown pastures. The remaining four (C. biflorus, C. preiurii C. echinatus and C. myosuroides) species are grown in limited pockets and maintained as genetic resources for basic and applied studies (Chandra and Dubey, 2010). Number of Cenchrus species …

IGC Proceedings (1997-2023)

Indian arid zone occupies about 31.7 million ha of land, of which 62% lies in western Rajasthan. The climate of the area is typically arid, characterized by hot dry summers, sub-humid monsoon and cold dry winters. The soils are coarse loamy sand with low level of nutrients. These factors render cropping an undependable proposition, while animal husbandry remains the main stake of the local people. Lasiurus sindicus, Cenchrus ciliaris, C. setigerus, Panicum antidotale, P. turgidum and Cymbopogon spp., are the main perennial grasses grow in this area. These grasses had three folds advantages in the arid agricultural economy, …

IGC Proceedings (1997-2023)

Globally land degradation affects about one sixth of the world population. In India, about 120 m ha area is affected with different kinds of land degradation. Under such situation, horti-pasture system provides best and economic alternative in conjunction with in-situ soil moisture conservation in general and semi-arid tropics in particular. India supports 55% buffaloes, 16% cattle, 20 % goats and about 4% sheep with deficit of 35% green fodder (525.51 mt), 10% dry fodder (453.28 mt) and 44% feed (28.4 mt) (IGFRI Vision, 2050). The per capita/day availability of fruits is 85 g as compared to average requirement of 120 …

Increased Photosynthesis Contributes Towards Improved Ovule-To-Seed Ratio In Iaa Treated Range Grasses, Chandan Kumar Gupta, Badre Alam, D. Vijay, M. Srivastava, D. R. Malaviya

IGC Proceedings (1997-2023)

Poor ovule-to-seed ratio is one of the major constraints in quality seed production in range grasses. Plant hormones per se or in the influence of external cues were known regulate the seed setting and their subsequent maturation in many crops. External application of hormones on the standing crops has shown very promising results but the physiological and biochemical phenomenon underlying such changes are not studied in detail. Exogenous application of different chemicals particularly during anthesis and post anthesis phases has increased the seed set in a number of species. Improved seed germination in Panicum maximum after foliar spray of indole …

Seasonal Influence On Seed Yield And Quality Of Anjan Grass (Cenchrus Ciliaris L.) Genotypes, R. P. Nagar, S. S. Meena

IGC Proceedings (1997-2023)

Cenchrus species are important perennial pasture component of Dichanthium-Cenchrus-Lasiurus grass cover of India associated with arid and semi-arid regions of tropical and sub tropical climate. It is adapted in wide range of environments due to its drought tolerance, deep roots, rapid response to summer rains, high biomass, resistance to overgrazing, palatable with crude protein 8-10% and 60-70% digestibility (Sawal et al., 2009). After well establishment these grasses give 8-10 t/ha dry fodder out of 3-4 cuts in a year and 100-250 kg/ha seed yield. There is a wide gap between demand and supply of Cenchrus grass seeds resulted about …

Effect Of Pretreatments On Seed Dormancy And Seedling Growth In Anjan Grass (Cenchrus Ciliaris), R. P. Nagar, S. S. Meena

IGC Proceedings (1997-2023)

Anjan grass (Cenchrus ciliaris L.) is native to tropical, sub-tropical Asia and Africa. It can grow on wide range of soils varying from sandy to harder heavy textured soils with annual rainfall of 350- 800 mm and up to an altitude of 1000 m. Among different rangeland grasses, it is considered palatable and nutritious grass for all kinds of grazing animals. It contains high percentage of protein (8-10%). One of the reasons for low production of pasture is poor plant density which might be due to low seed germination. The seed dormancy in range grasses hampers in establishment of …

Productivity Of Grasses In Association With Hardwickia Binata Under Rainfed Conditions, S. N. Ram, Ajoy K. Roy, A. K. Shukla

IGC Proceedings (1997-2023)

Adoption of silvipasture system on wastelands offers, without impairing the growth of trees, an extra yield of grass during monsoon season and top feed during summer seasons. The leaf fodder from the hardy trees and shrubs serve as an insurance against fodder scarcity during drought to the livestock. In view of this the present study was carried out to assess the productivity of different grasses in association with Hardwickia binata under moisture conservation practices under rainfed condition.

Goat is a future animal and plays a crucial role in providing livelihood and supplementary income to resource poor farmers and landless labourers of rural India. Goat rearing also ensures self-employment and act as a cushion in present climate change phenomena like drought and famine. Goats are found more in ecologically fragile arid and semiarid areas. Hence, it is imperative to address goat production under present scenario of climate change and food scarcity. The diverse challenges and constraints as growing population, increasing food, feed and fodder needs, natural resources degradation, climate change demands a reorientation of our strategies for goat …

Sustainable Production Of Guava Based Hortipasture System With Different In-Situ Soil And Moisture Conservation In Semi-Arid Region Of India, Sunil Kumar, A. K. Shukla, Harsh Vardhan Singh, A. Ahmed, A. K. Rai, R. Shrinivasan

IGC Proceedings (1997-2023)

In India, about 60 % of net sown area is rainfed, contributing 40 % of the total food production; it supports 40% of human and 60% of livestock population. Under such situation, incorporation of fruit trees along with animal husbandry in common farming system is advisable to improve income and nutritional security of the farmers. Horti- pasture system is the most ideal strategy to provide food, nutrition and income security to the people living in rainfed areas. System is socially accepted, ecologically feasible and economically viable for this region (Singh, 1996; Sharma, 2004; Kumar and Chaubey, 2008).

Leaf Blast Pyricularia Grisea Effects On Buffelgrass Forage And Seed Production In Northwestern Mexico, Martha Martin Rivera, Fernando Ibarra-Flores, Patricia Barrios Cardenas, Salomón M. Moreno, Fernando Ibarra Martin, Rafael Retes Lopez, Francisco Rivas Santoyo, Alfredo Aguilar Valdez

IGC Proceedings (1997-2023)

Common buffelgrass Cenchrus ciliaris (T-4464) is an introduced species intensively planted in Mexico to increase productivity on rangelands. Studies have shown that the species produces 5 to 10 times more forage as compared to native species on rangelands (Martin et al., 1995). Previous studies in the Gulf of Mexico have shown that the fungus Pyricularia grisea causes a disease in buffelgrass known as "leaf blight" and induce serious damage to the plant affecting forage production and nutritive quality (Ocumpaugh and Rodríguez, 1998; González, 2002). Injuries begin in the inferior leafs as small dark stains that later are converted in injuries …
