A field experiment was conducted to evaluate the performance of pasture legumes (Chtoria ternatea, Stylosanthes hamata, Centrosema pubescens, Atylosia scarabaeoides, Macroptelium atropurpureum, Phaseolus lathyroides, Vigna luteola, Glycine javanica used as intercropped element) in terms of nitrogen economy, biomass productivity and seed yield potential of Chrysopogon fulvus— a grass based management maintained for 1980–82 at the Research Farm, Indian Grassland and Fodder Research Institute, Jhansi under rainfed condition. Some legumes i.e. Atylosia scarabaeoides, Centrosema pubescens and Stylosanthes hamata enriched the nitrogen (74–90 kg/ha) status of soil which approximately doubled the biomass production (100–116 q/ha) as well as seed yield (78–81 kg/ha) of Chrysopogon fulvus. Furthermore the increased seed yield of C. fulvus under intercropping of legumes was attributed to its ear production, spike length and potential sink strength inducing the degree of germination (30 %). Potential performance of C. fulvus in the first year as compared to subsequent years might be due to its general transcript of the plant and have some interaction with rainfall. Extremely high and poor rainfall adversely affected the performance of C. fulvus.
A field experiment was conducted to evaluate the performance of pasture legumes (Desmanthus virgatus, Sesbania aegyptica, Macroptelmm autropurpureum, Desmodium tortuosum, Stylosanthes hamata used as in intercropped element) in terms of nitrogen economy, seed production efficiency and seed vigour potential of Panicum maximum– a grass based management maintained for 1986–88 at Research Farm, Indian Grassland and Fodder Research Institute, Jhansi under rainfed condition. Nitrogen economy under these intercropped pasture legumes was estimated on equating its value against nitrogen treatment i.e. 0, 10, 20, 30 and 40 kg N/ha. Among five intercropped legumes, Stylosanthes hamata and Macroptelium autropurpureum intercropping doubled the seed yield; S. aegyptica and M. autropurpureum brought out 46–55 per cent increase in biomass production over control value of 41.7 kg seed and 223.4 q biomass/ha respectively. These treatment showed 20–40 kg N/ha nitrogen equivalent value. Further more increased seed yield of Panicum maximum under intercropping was attributed to its better ear production, spike length and potential sink strength. Germination potential of harvested Panicum seeds under different treatments did not show variation among themselves. Potential seed production performance of Panicum maximum in the first year as compared to subsequent years might be due to its general transcript of plants and have some interaction with rainfall.
Field trials were conducted at Indian Grassland and Fodder Research Institute, Jhansi to find out appropriate agronomical technique, as method of planting, sowing date, time and dose of nitrogen application and synergistic effect of companion crops. Results demonstrated that (i) six weeks old seedlings of Cenchrus ciliaris have good vigour potential for vegetative propagation, (ii) its planting is most appropriate in last week of June, (iii) it requires 80 kg N in split doses (40 kg N at sowing and 40 kg N 30 days after sowing) and (iv) seed yielding potential of Cenchrus ciliaris further increased with companion crop of Sesame (Sesamum indicum). Thus it is pointed out that these agronomical requirement is necessary for reaping potential seed yield of Cenchrus ciliaris.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
