Utilization of urea super granule (USG) with raised bed cultivation system for transplanted boro (winter, irrigated) rice production is a major concern now days. A field experiment was conducted in the chuadanga district of Bangladesh to compare the two cultivation methods: deep placement of USG on raised bed with boro rice, and prilled urea (PU) broadcasting in conventional planting. Results showed that USG in raised bed planting increased grain yields of transplanted boro rice by up to 18.18% over PU in conventional planting. Deep placement of USG in raised bed planting increased the number of panicle m-2, number of grains panicle-1 and 1000-grains weight of boro rice than the PU in conventional planting. Better plant growth was observed by deep placement of USG in raised bed planting compared to PU in conventional planting. Sterility percentage and weed infestation were lower on USG in raised bed planting compared to the PU in conventional planting methods. Forty seven percent irrigation water and application time could be saved by USG in raised bed planting than PU in conventional planting. Deep placement of USG in bed saved N fertilizer consumption over conventional planting. Water use efficiency for grain and biomass production was higher with deep placement of USG in bed planting than the PU broadcasting in conventional planting methods. Similarly, agronomic efficiency of N fertilizer by USG in bed planting was significantly higher than the PU broadcasting in conventional planting. This study concluded that deep placement of USG in raised bed planting for transplanted boro rice is a new approach to achieve fertilizer and water use efficiency as well as higher yield and less water input compared to existing agronomic practices in Bangladesh.

SUMMARYExperiments made under dryland conditions in the post-monsoon period for 3 years showed that deep placement of N and P fertilizers at 12 or 18 cm led to better utilization than their shallow placement at 6 cm. Grain yield was maximal when the fertilizer was placed at 18 cm depth. The yield increase by deep fertilizer placement resulted from higher tiller survival till harvest. In these treatments water use efficiency and mineralizable N content in soil were higher.Of the two varieties tested the taller cultivar (C 306) yielded more in normal years but lodging due to a severe storm in one of the years reduced its yield considerably. While the yield of the tall variety was not much affected by variations in row distances, the dwarf (DL 153–2) responded to these variations and greatest yield was obtained at a row distance of 27·5 cm.

A field experiment was conducted at the Bangladesh Agricultural University (BAU) to find out possible effects of alternate wetting and drying irrigation (AWDI) on the yield, water use and water use efficiency (WUE) of Boro rice. The experimental layout was furnitured using split-plot design (SPD) with two modern varieties (MV) of rice viz. BRRIdhan 28 and BRRIdhan 29, which received four irrigation treatments randomly and was replicated thrice. The treatments ranged from continuous submergence (T1) of the field to a number of delayed irrigations (T2, T3 and T4) denoting application of 5 cm irrigation water when water level in the perforated PVC pipe fell 10, 20 and 30 cm below ground level (G.L.), respectively. The study revealed that treatment T1 attributed by the highest total water use (122.2 cm) and the lowest WUE (58.53 kg/ha/cm) produced the highest grain yield (6.86 t/ha). Treatment T2, on the contrary, gave the second highest yield (6.58 t/ha) and consequently the second highest WUE (69.48 kg/ha/cm) indicating quite a large water saving (15 cm) compared to treatment T1. The yields in treatments T3 (6.27 t/ha) and T4 (5.86 t/ha) were significantly lower at 1% level of significance compared to that of treatment T1. No significant effect was found either for the treatment or for the varieties on the number of effective and total tillers hill-1 nor did they affect 1000 grain weight. Reduced plant height, no. of effective tillers hill-1, grain yield, straw yield, biological yield and harvest index were found with the increasing water stress.

Raised Bed

A experiment comprising of 18 treatments i.e. two sowing methods (flat bed - 30 cm spacing, and raisedbed with two mungbean (Vigna radiata) rows bed–1 on 67.5 cm including 30 cm furrow), three seed rates (10, 15 and 20 kg ha–1 ) and three nutrient treatments (6.25 + 20.0, 9.38 + 30.0 and 12.5 + 40.0 kg N+P2O5 ha–1 ) was conducted at the Punjab Agricultural University, Ludhiana, India during kharif 2007 to 2009. The mungbean grain yield recorded in 2008 was similar in 2009 but higher than 2007. The increase of 3.94% in grain yield was recorded in raised-bed than in flat bed. The grain yield recorded with seed rate of 20 kg ha–1 was higher than with 10 kg ha–1 but similar with 15 kg ha-1 in 2006 and 2008. The grain yield recorded with 12.5 kg N + 40 kg P2O5 ha–1 was higher (p<0.05) than other treatments. Raised-bed planting with 33.3% lesser irrigation water used recorded 3.91% lesser water use than flat bed planting and 9.77% higher water use efficiency (WUE) (p<0.05) as compared to flat bed planting. Seed rate of 20 kg ha–1 recorded 35.9 and 8.9% higher (p<0.05) WUE than with 10 and 15 kg ha-1 . The highest WUE was recorded with 12.5 kg N + 40 kg P2O5 ha–1 which was higher (p<0.05) than 6.25 kg N + 20 kg P2O5 ha–1 but at par with 9.38 kg N + 24 kg P2O5 ha–1 .

SUMMARYContinuous rice–wheat (RW) cropping with intensive tillage has resulted in land degradation and inefficient use of water in Indo-Gangetic Plains (IGP) of South Asia. Replacement of rice with less water requiring crops such as soybean in RW system and identification of effective strategies for tillage management could result in sustainable cropping system in IGP. A field experiment was conducted for five years on an annual soybean–wheat (SW) rotation in the northwest IGP of India to evaluate effect of tillage, raised bed planting and straw mulch on yield, soil properties, water use efficiency (WUE) and profitability. In soybean, straw mulch reduced soil temperature at seeding depth by about 2.5 °C compared with no mulch. Straw mulch also resulted in slightly reduced water use and slightly higher WUE relative to their respective unmulched treatments. During wheat emergence, raised beds resulted in higher soil temperature by 1.6 °C compared with flat treatments. Bulk density and cumulative infiltration were greater in no-tillage compared with conventional tillage. Soil organic carbon in surface layer increased significantly after five years of experimentation. Soybean and wheat yields were similar under different treatments during all the years of experimentation. Soybean and wheat planted on raised beds recorded about 17% and 23% higher WUE, respectively, than in flat layout. The net returns from SW system were greater in no-tillage and permanent raised beds than with conventional tillage. Both no-tillage and permanent raised bed technologies can be adopted for sustainable crop production in SW rotation in northwest IGP. However, more studies are required representing different soil types and climate conditions for making recommendations for other regions of IGP.
