Performance of Rice with Varied Age of Seedlings and Planting Geometry under System of Rice Intensification (SRI) in Farmer’s Field in Western Terai, Nepal

Numbers of on-farm experiments were conducted to assess the performance of rice ( var. Sabitri) cultivated using System of Rice Intensification (SRI) with varied age of seedlings and planting geometry in four VDCs of Kailali, far western Nepal, under the aegis of Farmers’ Field School (FFS) during the rainy season of 2010. The experiment consisted of the seedlings of four age groups; 8, 15, 22 and 29-days and four planting geometry; 15x15cm2, 20x20cm2, 25x25cm2 and 30x30cm2 planted in four FFSs. Parameters such as number of tillers per hill, effective tillers /m2, 1000 seed weight (TGW) and grain yield were recorded. The results showed that 8-days-old seedlings produced significantly higher number of tillers per hill (40) and effective tiller per m2 (373), higher 1000 seed weight (21.10 g), grain yield (7.8ton/ha), net return (Rs.71900/ha) and B:C ratio (1.594). Similarly, crop planted in the geometry of 25x25 cm2 produced significantly higher number of tillers per hill(36), effective tiller per m2 (328), higher 1000 grain weight (21.50 g), grain yield (8.54mt/ha), net return (Rs.83350/ha) and B:C ratio (1.84).

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 farmers method. Less sterility was occurred (30 %) from farmers 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.

On-farm testing of IPM module in pigeon pea against pod borer complex was carried out on farmers’ field of two villages of district Jaunpur by KVK Jaunpur- 1 during 2018 and 2019 with three components viz., IPM module, farmers’ practice, and untreated check without plant protection measures. The IPM interventions viz., growing pod borer tolerant variety, two rows of maize as a border crop, installation of pheromone traps and bird perches with the application of botanical based insecticide azadirachtin 1% at the vegetative stage as an oviposition deterrence, application of chlorantraniliprole, and flubendiamide at critical stages of pod borer appearance during bud initiation and flowering stages. The reduction in the larval population and pod damage in IPM treated plots resulted in a significant increase in grain yield (1525 kg/ha) followed by farmers’ practice (1195 kg/ha) and in untreated check (857 kg/ha) The increase in grain yield was due to an additional investment of Rs.4100/-ha towards IPM module and farmers’ practice (Rs.2600/-ha). The excess expenditure incurred resulted in the highest net return of Rs.47550/-ha in the IPM module as compared to farmers' practice and in untreated check resulted in the lowest net return of Rs.18250/-ha.

Rice Intensification

Many benefits ofTrichodermainoculation for improving crop production have been documented, including growth and yield enhancement and the alleviation of biotic and abiotic stresses. However, because rice is usually cultivated under continuous flooding that creates anaerobic soil conditions, this limits the benefits of these beneficial fungi. Cultivating rice with the methods of the System of Rice Intensification (SRI) provides rice plants with a more favorable environment for their colonization by beneficial microbes in the soil because the soil is more aerobic under SRI management and contains more organic matter. This study evaluated the effects ofTrichodermainoculation of rice plants under SRI management compared with transplanted and flooded rice plants, considering also the effects of different means of fertilization and different varieties in rice. Experiments were conducted in 2015 and 2016 under the tropical climate of Nepal’s western terai (plains) during both the rainy season (July to November) and the dry season (March to July). The results indicated significantly better performance (P = 0.01) associated withTrichodermainoculation for both seasons and for both systems of crop management in terms of grain yield and other growth-contributing factors, compared to non-inoculated rice cropping. Relatively higher effects on grain yield were recorded also with organic compared to inorganic fertilization; for unimproved (heirloom) varieties compared with improved varieties; and from SRI vs. conventional flooded crop management. The yield increase withTrichodermatreatments across all trials was 31% higher than in untreated plots (4.9 vs 4.5 mt ha−1). WithTrichodermatreatment, yields compared with non-treated plots were 24% higher with organic SRI (6.38 vs 5.13 mt ha−1) and 52% higher with non-organic SRI (6.38 vs 3.53 mt ha−1). With regard to varietal differences, under SRI managementTrichodermainoculation of the improved variety Sukhadhan-3 led to 26% higher yield (6.35 vs 5.04 mt ha−1), and with the heirloom variety Tilkidhan, yield was 41% higher (6.29 vs 4.45 mt ha−1). Economic analysis indicated that expanding the organic cultivation of local landraces under SRI management should be profitable for farmers where such rice has a good market price due to its premium quality and high demand and when SRI enhances yield. These varieties’ present low yields can be significantly increased by integratingTrichodermabio-inoculation with SRI cultural methods. Other recent research has shown that such inoculation can be managed profitably by farmers themselves.

System of rice intensification (SRI) has been gaining momentum over the years in Tripura, one of the eastern states of India. To meet the growing rice demand, a rapid increase in paddy production is needed. Considering the growing importance of System of Rice Intensification (SRI) in the state, the need for such a study was felt and accordingly the present study was conducted in Sepahijala district of Tripura on the basis of highest area coverage under SRI among all districts of the State. SRI offers an interesting alternative to improve rice productivity. The present study was carried out to examine the comparative economics of SRI and conventional methods of rice cultivation in Tripura, India during the year 2016-17. For the study 120 sample farmers were selected by using multistage random sampling. The cost concepts were used are Cost A, Cost B and Cost C. This paper has compared the economics of SRI and the conventional methods of rice cultivation. It has shown that gross return and net return were much higher for SRI (Rs. 129000.50), (Rs. 67050.50) than conventional (Rs. 78444.00), (Rs. 27168.00), respectively. Similarly, the return over cost was higher for SRI (2.08) than conventional (1.52) methods. The present study concludes that SRI has a tremendous potential to increase the production of rice. Moreover, adoption of this technique by the farmers would give them higher yields which in turn will help them to earn more and improve their socio-economic situation. It has proved to serve as an alternative method for rice cultivation.

Rice Intensification

Weed emergence is among the most important problems in system of rice intensification (SRI) due to extensive planting geometry of at least 25 × 25 cm and moist environment, thereby leading to water loss by means of evaporation from the broad space as a result of the extensive planting geometry, and transpiration by the weeds. This reduces the additional water saving which affect the potential of SRI water productivity. It also reduces rice crop yields up to 70% if there is no weed control attempted. Nowadays, weed is being controlled by manual weeder which is labour demanding, while motorized weeders overcome the problem but still, it able to remove the weeds before rice canopy closure or 30 days after transplanting (DAT). This research was designed to evaluate the performance of UMAR-SRImat on soil moisture conservation and weed control. UMAR-SRImat was made using flaked rice straw and biodegradable adhesive. The design was laid out using randomized complete block design (RCBD) with three treatments [without soil cover (T1), SRImat (T2), UMAR-SRImat (T3)] and three replications. The analysis was conducted using analysis of variance (ANOVA). Volumetric moisture content (VMC) was determined at 18 and 25 DAT. Weeds were observed and recorded to determine the weed dry weight and weed control efficiency at 20, 40 and 60 DAT. Plant height per hill was measured at 30 and 50 DAT, likewise, the number of tillers were counted at 30 and 50 DAT. The result of VMC showed that UMAR-SRImat significantly conserved water higher than the control treatment at 18 and 25 DAT of 3100.0a and 2680.0a m3/ha, respectively. The effectiveness of UMAR-SRImat mulched was 100% at 20 DAT 99.64% at 40 DAT and 97.99% at 60 DAT. This research revealed that UMAR-SRImat mulch could retain soil moisture and suppressed weeds up to 60 DAT.
