“…This has to do with the incorporation of biomass of dhaincha and mungbean in soils (Table 2). This result is consistent with that of Reddy et al (1995) who stated that incorporation of biomass released nutrients to soils and enhanced crop nutrient uptake and thereby increased crop yields. However, straw yield was not significantly influenced by cropping pattern treatments as was observed similarly in the study conducted one year before.…”

A series of experiments using nine treatment combinations comprising three tillage practices (zero tillage, conventional tillage and deep tillage) and three cropping patterns (wheatfallow- T. aman, wheat–mungbean-T. aman and wheat-dhaincha-T. aman) were examined in a split- plot design at Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh during 2008-2009 and 2009-2010 to study the effect of different tillage practices and cropping patterns on soil physical properties and crop productivity in a previously puddled soil. Soil physical properties viz. bulk density, particle density and porosity showed insignificant result due to tillage practices and cropping patterns but soil moisture retentive properties demonstrated significant outcomes. Deep tillage with dhaincha (Sesbania rostrata) and mungbean (Vigna radiata L. Wilczek) biomass incorporation conserved moisture in the soil profile and improved other soil physical properties i.e. reduced the bulk density, increased porosity and available water content of soil. The highest grain yield of wheat and rice was recorded in the deep tillage with wheat-dhaincha-T. aman cropping pattern and lowest in zero tillage with fallow based cropping pattern.

“…Lack of understanding of water balances, of linkages between surface water and groundwater and of the difference between beneficial and non-beneficial uses of water have usually resulted in poor effectiveness of water saving approaches (AIT, 2009). Nevertheless, water saving practices such as alternate wetting and drying, soil compaction and intensive puddling can contribute to water saving and increased water productivity (Reddy and Hukkeri, 1979;Reddy and Hukkeri, 1980;Reddy and Hukkeri, 1983).…”

When water supplies are restricted, so that full evapotranspiration demands cannot be met, limited irrigation is practised. Management strategy of limited irrigation is to optimise production per unit of applied water rather than to maximise yield per unit of land. Principles that help to facilitate limited irrigation strategies can be broadly grouped into three: agricultural water management, crop considerations and agronomic options. When anticipating low water year, choose crops which maximise production with limited water. In decreasing order of efficiency, short season indeterminate and long season indeterminate crops should be chosen judiciously. Deficit irrigation practices, localised irrigation methods, reducing water losses,conjunctive use of water resources etc can help minimise yield losses due to soil moisture stress. Additional agronomic management options that can maximise production include conservation tillage, advancing or delaying planting dates in order to coincide the crop’s critical period with water availability, decreasing plant competition byreducing seeding density and controlling weeds. Available options to address the challenge of limited irrigation have been briefly presented.

“…Also, effectiveness with respect to weed control as well as soil moisture preservation and increasing available soil nutrients are the benefits of second tillage. Reddy and Hukeri (1983) found that performing puddling at three replications in 3 to 12.5 cm depth reduces the Eleocharis dulcis weed population to 49%. Kuipers (1983) showed that land preparation has different effects on weed species.…”

“…Rahmati and Salokhe (2001) found that in Thailand, rice yield increased with tillage due to less weeds and subsequent reduction in competition for soil nutrients and water. Reddy and Hukeri (1983) showed that tilling twice improved grain yield in two out of four methods (second plowing once, second tillage twice, conventional plowing of the area, compressing soil surface). Increased rice biomass, rice plant height, number of tillers, panicle length, number of grains per panicle and grains weight led to a 4.5 ton ha -1…”

Using non-chemical weed control methods can play an important role in reducing herbicide use as well as protecting the environment. Appropriate land preparation especially puddling has been known as one of the best factors for weed control in rice fields. Plowing once in late winter and tilling again at one or two weeks before transplanting in spring is the current method in Iran. Number of tillages and type of equipment used depends on conditions and farming system in different sites in Iran. Kind of equipment and number of tillage operations may affect weed density. An experiment was conducted in 2011 with 6 treatments in RCBD. The treatments included: conventional method with one or two tillage operation (tillages separated by a 10-day interval), tilling once or twice with a rotivator, or tilling once or twice with a cone-puddler. These trials were conducted in rice fields of Jhad Research Institute of Iran (JRII) with 3 replications. Main weeds were: Echinochlea crus-galli (water grass), Cyperus difformis (small flower) and Alisma plantago-aquatica (water plantain). The results indicated that number of tillages and kind of equipment affected weed population and density. The best treatment was conventional method of plowing followed by two tillage operations which reduced weed density 2/3 times in comparison with the worst treatment (cone puddler with one tillage operation).
