“…Of the various approaches contemplated to break the existing yield barriers in rice, hybrid rice technology offers an opportunity to boost the yield of rice under fragile conditions as hybrid rice varieties have a yield advantage of 15-20% over the conventional high yielding varieties (Virmani et al, 1996). The success story of hybrid rice technology in China (Lin and Yuan, 1980) as leading producer of hybrid rice in the world (Swaminathan, 2006) and some other countries along with India has been witnessed as an important and readily adoptable genetic option to increase the rice production and offers a viable solution to meet the ever increasing food challenge in different countries (Rai, 2009;Sanghera and Wani, 2008;Virmani et al, 2003).…”

The nature and magnitude of heterosis and combining ability was studied in 18 F 1 rice hybrids involving three CMS lines and six testers using line × tester analysis. The analysis of variance for combining ability of all the traits showed that variances due to treatments, parents, hybrids were highly significant. The line 'CRMS 32A' and testers viz. 'Super rice-8' , 'R 1099-2569-1-1' and 'Jitpiti' were identified as good general combiners. The significant differences between lines x testers interaction indicates that SCA attributed heavily in the expression of these traits and demonstrates the importance of dominance or non additive variances for all the traits. The hybrid 'CRMS 32A'/'R 1099-2569-1-1' and ' APMS 6A'/'Super rice-8' were promising for grain yield. The magnitude of relative heterosis, heterobeltiosis and standard heterosis were also estimated for different characters. A high degree of relative heterosis was observed for grain yield (20.45-82.37%) in the hybrids viz.,

“…These frameworks include "ecological intensification" (21) and "evergreen revolution" (22); they share a view of cropping systems as ecosystems that should be designed to make maximum use of fixed resources (land, light, and favorable growing conditions) and optimum use of agricultural inputs (water, fertilizer, and other chemicals) to produce useful products. Such systems can draw upon features of traditional agricultural knowledge and add new ecological information into the intensification process (23).…”

China and other rapidly developing economies face the dual challenge of substantially increasing yields of cereal grains while at the same time reducing the very substantial environmental impacts of intensive agriculture. We used a model-driven integrated soil-crop system management approach to develop a maize production system that achieved mean maize yields of 13.0 t ha −1 on 66 on-farm experimental plots-nearly twice the yield of current farmers' practices-with no increase in N fertilizer use. Such integrated soil-crop system management systems represent a priority for agricultural research and implementation, especially in rapidly growing economies.environmental integrity | nutrient use efficiency | crop yield | nitrogen fertilization | smallholder farm

“…Green Revolution technology has been criticized for its defi ciencies (Swaminathan 2006 ;Robertson and Swinton 2005 ). Economists stress that, because marketpurchased inputs are needed for production, only resource-rich farmers can take advantage of high-yielding crops.…”

The "Green Revolution" has increased food production to meet world population growth, therefore global food production is at present suffi cient to feed all the world's people. However, the modern agricultural system is no longer sustainable due to deterioration of soil conditions. Alternative agricultural methods that aim to conserve biodiversity and soil functioning are not intensively studied, thus the productivity of alternative methods is often not compatible with conventional agricultural practice, and most people are skeptical of the feasibility of introducing alternative methods. Recent advancements in studies of biodiversity and ecological functioning are now supporting early trials by advanced farmers, who respect biodiversity in their fi elds. In this review, I would like to present some ecological theories to support biodiversity agriculture and its potential to support human populations.
