Field experiment was conducted in the dry season of 2014 in the Golinga Irrigation farm (Latitude 09°21'N and Longitude 0°56' W) at Golinga, in the Northern Region, Ghana. This was to evaluate the System of Rice Intensification (SRI) for enhanced grain yield, yield components and economic viability of Gbewaa rice variety production under irrigated conditions. The experiment was laid out in Randomized Complete Block Design with three replications. The treatments comprised four SRI and two Farmers’ Practice treatments viz: FP 1, SRI 1, SRI 2, SRI 3, SRI 4 and FP 2. Under all SRI treatments, seeds were nursed and seedlings were transplanted singly and widely (25 cm × 25 cm), irrigated intermittently and soil earthing up regularly. SRI 1 and FP 2 each received only 13 t ha-1 compost, SRI 2 and FP 1 each received an amount of 37.5 kg ha-1 each of N, P2O5 and K2O as basal application and 26.25 kg ha-1 of N as top dressing while SRI 3 and SRI 4 both received 13 t ha-1 compost followed by either 18.75 kg ha-1 each of N, P2O5 and K2O as basal application or 13.13 kg ha-1 of N as top dressing respectively. SRI 1 plants established best and took the longest days to flower. Higher number of grains per panicle was obtained in SRI 3. SRI 2 produced the highest plant height, panicle length, panicle weight, tiller count and plant biomass. SRI 2 also produced the highest yield (4026 kg ha-1) which was not statistically different from the yields produced in SRI 3 (3866 kg ha-1) and SRI 4 (3737 kg ha-1) as compared with the control – FP 1 (2410 kg ha-1). The benefit – cost analysis showed that SRI 2 (1.97) was the most profiting entry followed by SRI 4 (1.35) and SRI 3 (1.31). Where mineral fertilizers are available and affordable, SRI 2 could be chosen under irrigated condition.

An experiment was conducted at the Bangladesh Rice Research Institute regional station, Rangpur to investigate the performances of different establishment methods of Boro rice; variety BRRI dhan29 in light texture soil during Boro 2004-05 and 2005-06 seasons. Five crop establishment methods were tested in a randomize complete block design with three replications. The methods were: 1. Conventional transplanting method 2. System of Rice Intensification (SRI) method, 3. Farmers practice, 4. Seedling throwing method and 5. Direct-Wet Seeded Rice(DWSR) using drum seeder method. Grain yield was influenced by different crop establishment methods in both the seasons. The highest mean grain yield was obtained by BRRI recommended conventional transplanting method (6.27 t ha-1) followed by SRI method (5.70 t ha-1). The highest number of panicles m-2 was obtained from wet DSR by drum seeder method (341 m-2). Effectiveness of tiller (92%) was obtained from the SRI method. The largest number of filled grains per panicle (76) was obtained from the SRI method. The highest 1000-grain weight (23.2 g) was obtained by the farmer’s method. Less sterility was occurred (30 %) from farmer’s methods. The highest growth duration (175 days) was observed in farmer method. But the highest field duration of BRRI dhan29 (145 days) was observed in wet DSR using dream seeder.

Field experiment was conducted at Rice Research Station, Bankura during kharif season 2009 and 2010 to study the yield potentiality and spatial requirement of rice varieties in system of rice intensification (SRI) under red and laterite zone of West Bengal. The experiment was laid out in a randomized complete block design (RCBD) in a three replications with two rice varieties (Swarna and Lalat). Performances of swarna and lalat varieties in SRI as compared to conventional method of rice cultivation (CMRC) were investigated. Swarna (MTU 7029) has yielded maximum grain yield (6.07, 5.66 and 5.86 t ha-1 during 2009, 2010 and in pooled, respectively) from the treatment T7 (25 × 25 cm spacing) under SRI. Lowest grain yield (3.55, 3.23 and 3.38 t ha-1 during 2009, 2010 and in pooled, respectively) was recorded from treatment T9 (Lalat at 20 × 15 cm spacing) under CMRC. SRI technology has potential in increasing more grain yield, it saves seed requirement and irrigation water and chemical fertilizer considering than conventional method of cultivation. Rice cultivation is more sustainable and profitable for the farmers in SRI under the red and laterite zone of West Bengal.

A two year longer on-farm research on conservation agriculture was conducted at Bhangnamari area of Bangladesh during November-June in 2014-15 and 2015-16 to evaluate the performance of non-puddled rice cultivation under increased crop residue retention. The rice variety BRRI dhan28 was transplanted under puddled conventional tillage (CT) vs. non-puddled strip tillage (ST) with 50% standing residue (R50) vs. conventional no-residue (R0) practice. The treatments were arranged in a randomized complete block design with four replications. There were no significant yield differences between tillage practices and residue levels in 2014-15. But in the following year, ST yielded 9% more grain compared to CT leading to 22% higher BCR. Retention of 50% residue increased yield by 3% over no-residue, which contributed to 10% higher benefit-cost ratio (BCR). Results of this two year on-farm study confirmed that the ST combined with 50% residue retention yielded the highest grain yield (5.81 t ha-1) which contributed to produce the highest BCR (1.06).

The "System of Rice Intensification"(SRI) represents a sustainable alternative to improve household yields and incomes. This study aimed to evaluate the yields and the profitability of the SRI and the Traditional Practices (TP) in Ziguinchor district, Senegal. A directed sampling based on criteria for selecting the system used and the cultivated varieties common to both systems was applied to collect the yield parameters and yields of paddy rice. Thus, 18 producers in the Badiate, Essyl, and Fanda sites were selected, nine per system and four 1 m2 yield squares were installed in each selected producer plot. A total of 72 yield squares, 36 per system, were installed, and an individual questionnaire was randomly administered to 55 producers using at least one of the systems to collect data on rice production and costs. The yield parameters including the number of fertile tillers per m2, the number of spikes, the weight of the 1000 grains are significantly higher (p<0.05) in the SRI including yield compared to the traditional system. Transplanting density and plant duration are higher in TP (26±5.6 plants/m2 and 26 days) than in SRI (16±0.4 plants/m2 and 16 days). The lower the transplanting density, the higher the yield parameters and the yield. The economic profitability, determined based on the benefit/cost ratio, is higher in SRI (1.5) than in TP (1.2). The SRI required a lot of technicality in its implementation and generated more cost of production. However, SRI was more productive and economically more profitable than the traditional system.

Rice is an annual plant belongs to family Poaceae. It is the major staple food crop of Nepal and can be grown from plain to mountainous regions of Nepal. The crop varieties differ from each other in terms of production cost, gross return and gross margin. The objective of this study was to analyze benefit cost ratio for production of different rice varieties. The study was carried out in Kapilvastu district of Nepal in 2018. A sample size of 120 respondents were selected randomly. Four different rice varieties: Gorakhnath, Radha-4, Ramdhan, and Sawa were used for the study. The primary data were collected through household survey using interview schedule. The data were analyzed using Statistical Package for Social Sciences and Microsoft Excel. The average cost of production was amounted to NRs. 77,100/ha for all four rice varieties. Sawa variety had the highest gross return (NRs. 1,01,212.5/ha). The benefit cost ratio was observed highest for Sawa (1.312) and lowest for Radha-4 variety (1.005). Sawa is the most economic rice variety in terms of gross and net production in the study area. The findings will help farmers to choose and cultivate rice variety with greater profitability. It is recommended that concerned authorities should give emphasis on subsidies, farmers training and ensuring floor price of rice.  Int. J. Appl. Sci. Biotechnol. Vol 7(2): 222-226

The experiment was conducted to find out the effect of plant spacing on the performance of rice variety IR-64 and IR64-Sub1 under conventional and Submerged condition at the National Rice Research Institute (NRRI), Cuttack, Odisha during the Rabi season of 2018. Different planting densities were maintained using different spacing's. These include (S1) 15 cm × 10 cm, (S2) 15 cm × 20 cm. The experiment was laid out in a randomized complete block design with 3 replications spacing of 15 cm × 10 cm with produced the highest grain yield of 350 gm-2 in submerged condition on IR64-Sub1 rice cultivar, which was significantly higher than the yield with recommended density (15 cm × 10 cm with IR64 Sub1). This yield was increased due to higher number of panicles m-2. This result suggests that higher planting density (15 cm×10 cm) rather than increased number of seedling hill-1 is necessary for getting higher yield of IR-64Sub1 rice cultivar in continuous submerged condition (where V1=IR 64, V2=IR-64 Sub1, S1=15 cm×10 cm, S2=20 cm×15 cm).
