“…Green manures are excellent providers of N to a subsequent rice crop, reducing the need for fertilizer N (Yadvinder- Singh et al, 1991;Becker et al, 1995). Losses of N from applied green manure are oft en lower than from urea.…”

“…Losses of N from applied green manure are oft en lower than from urea. Whereas the average loss from urea was 35% of the applied N, the average loss for green manure was 14% of the applied N for 18 15 N balance studies (Becker et al, 1995). Losses of N from green manures can be reduced by bett er synchronizing the release of N from the green manure residues with N assimilation by rice.…”

Soils with continuous or intermitt ent submergence by water are widely distributed worldwide. They occur in a range of ecosystems including rice (Oryza sativa L.) fi elds, wetlands, estuaries, and fl oodplains. Such ecosystems oft en occur at low elevation in the landscape and are poorly drained with high retention of water. In addition, some upland areas with poor drainage can undergo periodic submergence and soil saturation. Moreover, the sediments in ocean, lake, and stream bottoms have similar biogeochemical and physical characteristics and N transformations as submerged agricultural soils.Rice fi elds surrounded by earthen levees to retain rain and irrigation water and ensure soil submergence are one of the world's major agricultural ecosystems. Rice is a staple food for nearly half the world's population, and about 95% of the global rice production occurs on fi elds with soil submerged during at least part of the rice-cropping period. The sustained productivity of this rice ecosystem, which ensures production of suffi cient food for a growing world population, relies heavily on the input and management of N.Nitrogen transformations in submerged soils are markedly diff erent from those in drained, aerated soils. These diff erences aff ect the prevalent soil microorganisms and microbial activities and the turnover, availabilility, and losses of N. To deal with the diff erences in N transformations between submerged and drained soils it is necessary to understand the biogeochemical conditions existing in submerged soils. This chapter is an update of an earlier review by Patrick (1982).

Continuous adoption of rice-rice cropping system has led to deterioration of soil quality resulting in a serious threat to its sustainability in high rainfall zone of South Gujarat, India. Therefore crop diversification with wider choice in the production of a variety of crops is being promoted to restore the soil quality. A field experiment was conducted at Navsari, India during 2003-2007 on heavy black soil to evaluate the production potential, sustainability, resource-use efficiency and economics of 10 cropping systems based on rice (Oryza sativa L.). System productivity of rice -fenugreek -okra was the highest (25.73 ton/ha) followed by rice-onioncowpea (24.15 ton/ha). Lowest System productivity was registered with rice-wheat-fallow system (7.85 ton/ha). Sustainable yield index (0.94), production efficiency (102.94 kg/ha/day), and field water use efficiency (32.99 kg/ha-cm) were maximum with rice -fenugreek -okra system. Similarly, net return (Rs 96286/ha), net return per rupee invested (Rs 2.84), and production efficiency (Rs 385.14 /ha/day) and field water use efficiency (Rs 1234.43/ha-cm) in economic terms was maximum with rice -fenugreek -okra cropping sequence. Thus rice -fenugreek -okra was the most productive, sustainable, resource-use efficient and remunerative cropping system followed by rice-onion-cowpea system.

“…Thus it becomes a modest source of N for resource-poor farmers (McDonagh et al, 1995). Inclusion of grain legumes plays an important role for increasing cropping intensity or even sustaining crop productivity along with improving nutritional status of the people and maintaining soil health (Becker et al, 1995;Norman et al, 1984).…”

The study was conducted at the farmers field in Sylhet under AEZ 20 during three consecutive years 2012-13, 2013-14 and 2014-15 to determine the productivity and profitability of cropping patterns viz., IP: improved pattern (Mung bean-T. aus-T. aman rice) and FP: farmer's pattern (Fallow-T. aus-T. aman rice) through incorporation of high yielding varieties and improved management practices. The experiment was laid out in randomized complete block design with six dispersed replications. Results showed that the improve pattern with management practices provided 10.85 and 14.32% higher grain yield of T. aus and T. aman rice, respectively; also contributed more T. aman mean rice equivalent yield (11.81 t ha -1 ) compared to farmer's pattern. Mean sustainable yield index (77.63%), production efficiency (47.88 kg ha -1 day -1 ), and land use efficiency (67.66%) were maximum in Mung bean-T. aus-T. aman rice cropping system. Similarly, the highest mean gross margin (Tk.126762 ha -1 ) with benefit cost ratio (2.10) was obtained from improved pattern. Three years results revealed that 42% extra cost provides an ample scope of considerable improvement of the productivity of improved pattern with the inclusion of Mungbean before T. aus rice.
