Aman Rice Cropping in Sylhet Region 2020-10-24T13:28:46+00:00 MI Nazrul mi_nazrul@yahoo.com <p>The study was conducted at the farmer’s field in Sylhet under AEZ 20 during three consecutive years 2016-17, 2017-18 and 2018-19 to determine the productivity and profitability of cropping patterns viz. IP: improved pattern (Mustard-T. Aus-T. Aman rice) by introducing high yielding varieties and improved management practices and FP: farmer’s pattern (Fallow-T. Aus-T. Aman rice). The experiment was laid out in randomized complete block design with six dispersed replications. Results showed that the improved pattern with management practices provided 6.88 and 22.84 % higher grain yield of T. Aus and T. Aman rice, respectively; also contributed higher mean rice equivalent yield (9.44 t ha<sup>-1</sup>) compared to farmer’s pattern.Sustainable yield index (0.36), production efficiency (39.75 kg ha-1day<sup>-1</sup>), and land use efficiency (75.98 %) were maximum in Mustard-T. Aus- T. Aman rice cropping system on an average. Similarly, the highest mean gross margin (Tk.1,12,425 ha<sup>-1</sup>) with benefit cost ratio (2.13) was obtained from improved pattern. Three years results revealed that 24% extra cost provides an ample scope of considerable improvement of the productivity with the inclusion of Mustard before T. Aus rice in improved pattern.</p> <p><em>Bangladesh Agron.

Two salinity levels, i) control (0mM NaCl) and ii) 80 mMNaCl were maintained after 14 days of sowing to harvest. The plant growth regulators i) Humic acid (HA): a) @ 5 gL<sup>-1</sup> water b) @ 10 gL−1water ii) Gibberellic acid (GA3): a) @10 g L-1water b) @20 g L-1water iii) Salicylic acid (SA): a) @ 50 g L-1water b) @ 100 g L-1water were sprayed at 7 days interval from salt imposition. The experiment was in a completely randomized design (CRD) with three replications. Results revealed that plant growth regulators improved the growth and yield performance of Foxtail millet under both control and saline conditions. Amelioration of salinity tolerance in Foxtail millet was well associated with lower proline content, higher chlorophyll content and SPAD value as well as dry matter production, which facilitated the Foxtail millet yield due to application of plant growth regulators. Among the plant growth regulators, humic acid (HA) @ 5 g L-1 water was the best treatment to improving the salinity tolerance in foxtail millet under saline condition.</p> <p><em>Bangladesh Agron.

Seven soybean genotypes namely,i) G00081 ii) G00056 iii) Shohag iv) G00078 v) G00137 vi) G00035 and vii) G00060 were grown in two watering regimes <em>viz</em>. control (80% of the field capacity) and water deficit stress (50% of the field capacity). Morpho-physiological traits including plant height, number of leaf, relative water content, water saturation deficit, chlorophyll, proline, dry matter and yield were investigated. Results indicated that genotypic variability was found in water deficit stress tolerance in soybean. It was found that leaf of the genotype G00081 maintained higher water content, higher accumulation of prolineas well as less reduction of chlorophyll compared to other genotypes studied. Total dry matter accumulation and grain yield plant<sup>-1</sup>was also higher in this genotype. Genotype G00081 also showed relatively higher water deficit stress tolerance. On the contrary, G00035 was found to be susceptible showing lower yield. Higher water deficit stress tolerance in G00081 was attributed to higher relative leaf water and chlorophylls with accumulation of higher amount of proline.</p> <p><em>Bangladesh Agron.

The experiment was conducted in split plot design with three replication. The tillage options viz. (i) Strip tillage (ST) (ii) Permanent bed (PB) and (iii) conventional (CT) tillage; two crop residue management, viz. (i) 0%=no residue and (ii) 30% residue retention were studied. The results indicated that keeping 30% crop residue in the field with minimum disturbance of soil had significant contribution on grain yield of wheat-maize-rice sequence compare to conventional practice of well-till without crop residue retention.The permanent bed planting system gave the highest yields of wheat (4.37 tha<sup>-1</sup>), maize (7.31 tha<sup>-1</sup>) and rice (4.40 tha<sup>-1</sup>) and followed by strip tillage and lowest in conventional tillage. Among the residue management, 30% residue retention showed the highest yields of wheat (4.46tha<sup>- 1</sup>), maize (7.39 tha<sup>-1</sup>) and rice (4.69 tha<sup>-1</sup>). Considering economic performance of all tillage systems, the permanent bed planting system performed the best among all other tillage options and followed by strip tillage. Contrarily, 30% residue retention gave the highest yield and increased 0.12-0.14% organic matter into the soil with more productive.The results indicates that, both tillage systems coupled with 30% residue retention might be a good option for higher yield as well as soil fertility for Wheat-Maize- Taman rice cropping pattern in drought prone areas of Bangladesh.</p> <p><em>Bangladesh Agron.

The trial comprises five packages of practices including crop residue retention, seeding methods with tillage options imposed on the component crops in the same cropping pattern. The results indicated that keeping standing 30% crop residue in the field with minimum disturbance of soil had significant contribution on grain yield of wheat-mungbean-rice sequence compare to conventional practice of well-till without crop residue retention. System productivity and fertility were evaluated under five levels of tillage options (zero, strip, raised bed, minimum tillage by power tiller operated system (PTOS) and conventional tillage practice (CTP) in a RWM cropping pattern. Both permanent raised bed and strip till with 30% straw retention produced the highest productivity in all years and the lowest yield was also found from conventional practice with 30% straw retention.Soil organic matter in surface soil had increased by 0.12% after 3years crop cycles with 30% SR from rice and wheat and full residue retention from mungbean crop. Straw retention is an important component of soil management and may have long term positive impacts on soil quality. The combination of raised bedsystems and strip tillage with 30% residues retained appears to be a very promising technology for sustainable intensification of wheat-mungbean-rice croppingpattern in dry zone areas.</p> <p><em>Bangladesh Agron.

However, most of the aromatic rice varieties in Bangladesh do not meet the expected criteria. Therefore, this study was undertaken to detect short-statured rice plants with aromatic and long to medium slender grain where twelve advanced rice lines (derived from the local rice germplasm) with a local check Kataribhog were evaluated. All the genotypes demonstrated significant variation for different parameters such as plant height at harvest, yield per hectare, grain length, grain size, grain shape, and aroma. At harvest, the shortest plant height was obtained from SAU ADL11 (107.09cm), and it was statistically similar to SAU ADL4 (111.68cm) and SAU ADL5 (111.89cm). However, the plant height of check variety Kataribhog was 167.17cm. The highest grain yield per hectare was found in SAU ADL5 (4.79 tha<sup>-1</sup>), where it was 2.71 tha<sup>-1</sup> in Kataribhog. Besides, the grain yield of shorter genotypes SAU ADL4 and SAU ADL11 was 3.47 t ha<sup>-1</sup> and 3.84 t ha<sup>-1</sup> , respectively. The SAU ADL1 provided the highest kernel length (7.31mm), and the lowest kernel length (4.87 mm) was recorded in the check. Kernel length of short-statured genotypes ranged from 7.01 mm to 6.57 mm. Kernel size of all evaluated genotypes was long to medium; whereas, it was short for Kataribhog. Kernel shape of these short-statured genotypes was slender to medium. In case of aroma, SAU ADL3, SAU ADL5, SAU ADL7, SAU ADL9, SAU ADL10, and SAU ADL11 were moderately aromatic, and other genotypes were non-aromatic. However, Kataribhog was strongly aromatic. Finally, SAU ADL5 and SAU ADL11 were evaluated as important germplasms in respect of different characters such as shortstatured plant, long to medium slender grain, and aroma. These two lines could be potential inbreed aromatic rice genotypes for Bangladesh.</p> <p><em>Bangladesh Agron.

Rice yield was the highest (3.87t ha-1) in sole cropping, and intercroppingresulted insignificant rice yield reduction. Although inintercropping rice yielddecreased, but increased both gross margin and benefit cost ratio (BCR) as compared to rice sole cropping. Among the vegetables, gimakalmi performed the best followed by red amaranth in terms of yield and 125% recommended fertilizer was the best fertilizer dose. Gimakalmi intercropped with rice following 125% recommended fertilizer showed the highest gross return and BCR (2.53).

However, the nutrient requirement of mustard especially for the short duration variety is very much important to obtain higher yield. A field experiment was conducted to assess the requirement of major nutrients (N, P, K, and S), and to recommend fertilizers for short-duration mustard variety BARI Sarisha-14. There were 8 treatments T<sub>1</sub>=100% soil test based (STB) nutrients (N, P, K, S, Zn &amp; B @ 90, 25, 60, 15, 2 &amp; 1 kg ha<sup>-1</sup>, respectively) as per Fertilizer Recommendation Guide (FRG,2012), T<sub>2</sub>=T<sub>1</sub>+ 25% N of FRG, T<sub>3</sub>=T<sub>1</sub>+ 25% NP of FRG, T<sub>4</sub>=T<sub>1</sub>+ 25% NK of FRG, T<sub>5</sub>=T<sub>1</sub>+ 25% PK of FRG, T<sub>6</sub>=T<sub>1</sub>+ 25% NPK of FRG, T<sub>7</sub>=75% of T<sub>1</sub> and T<sub>8</sub>= native nutrient (control). The experiment was laid out in Randomized Complete Block Design with 3 replications. The results revealed that yield and yield parameters of mustard weresignificantly influenced by the nutrient levels. The highest value of almost all the yield components and yield were obtained in T6 among the treatments. The highest seed yield (1.68 t ha<sup>-1</sup>) and the maximum stover yield (2.96 t ha<sup>-1</sup>) were obtained from the treatment (T<sub>6</sub>) containing 100% STB nutrients with additional 25% NPK among the fertilizer treatments. The seed yield value was statistically higher than all other treatments except the treatment where100% STB nutrients with additional 25% NP were used (T<sub>3</sub>). The highest seed yield and stover production were attributed tothe yield contributing parameters. The highest amount of all the nutrients content was found in the treatment T6 that was followed by T<sub>3</sub> and T<sub>4</sub> and the lowest in T<sub>8</sub>. The highest amount of N, P, K, and S content in seed of the treatment T<sub>6</sub> was 3.75, 0.97, 0.96 and 0.78%, respectively. The highest yield was accredited to the highest amount of nutrient content in seed. It could be concluded that the treatment T<sub>6</sub> (STB fertilizer dose + 25% NPK of FRG) would suitable for short duration Mustard (BARI Sarisha-14) for getting higher yield and better performance.</p> <p><em>Bangladesh Agron.

Six treatment combinations viz. T<sub>1</sub>= Soil test based fertilizer dose for HYG, T<sub>2</sub> = IPNS with 5 tha-1cowdung, T<sub>3</sub>= IPNS with 5 tha<sup>-1</sup> compost, T<sub>4</sub>= IPNS with 1.5 t ha<sup>- 1</sup>vermicompost, T<sub>5</sub>= Farmers’ practice and T<sub>6</sub>= Absolute control were tested. The experiment was laid out in a randomized complete block design with 3 replications and BARI Sunflower<sup>-2</sup> was used as test crop.The IPNS treatment combinations are significantly differentfrom rest of the treatments in terms of yield and economic return. Application of treatment IPNS with 1.5 tha<sup>-1</sup>vermicompost significantly increased all of the parameters such as the plant height, head diameter, number of seed per head,1000 seed weight, seed yield and stover yield. The significantly highest seed yield (2.19, 2.23 and 2.06 t ha<sup>-1</sup> at Noakhali, Bargunaand Satkhira, respectively) was recorded in IPNS with 1.5 tha<sup>-1</sup>vermicompost treated plot (T<sub>4</sub>) while the lowest seed yield (1.05, 1.10 and 1.02 t ha<sup>-1</sup> at Noakhali, Barguna and Satkhira, respectively) was observed in absolute control treatment (T<sub>6</sub>). Salinity level increased at slower rate in T<sub>2</sub>, T<sub>3</sub> and T<sub>4</sub>, treatments where IPNS based nutrient management packages were imposed.During the crop growing period soil salinity ranged from 0.62 to 9.72dS m<sup>-1</sup>, 0.58 to 9.23dS m<sup>-1</sup>, 0.73 to 9.86dS m<sup>-1</sup> at Noakhali, Barguna and Satkhira, respectively from emergence to maturity stages of the crop. The highest net return (50790 Tk. ha<sup>-1</sup>, 52765 Tk. ha<sup>-1</sup> and 43940 Tk. ha<sup>-1</sup> at Noakhali, Barguna and Satkhira, respectively) as well as BCR (1.75, 1.78 and 1.67 atNoakhali, Barguna and Satkhira, respectively) were obtained from T4 treatment (IPNS with 1.5 tha<sup>-1</sup>vermicompost) whereas the lowest net return (14900 Tk. ha<sup>-1</sup> ,15175 Tk. ha<sup>-1</sup> and 11570 Tk. ha<sup>-1</sup> at Noakhali, Barguna and Satkhira, respectively) and BCR (1.40, 1.33 and 1.26at Noakhali, Barguna and Satkhira, respectively) were obtained from control (T6) treatment. The overall results indicated that IPNS with 1.5 tha<sup>-1</sup> vermicompostis more effective than other fertilizer management packages in respect of yield as well as economic return for sunflower cultivation in the coastal charland of Bangladesh.</p> <p><em>Bangladesh Agron.

Ten treatments were included in the study as, T<sub>1</sub> (sole wheat), T<sub>2</sub> (sole mustard), T<sub>3</sub> (wheatmustard in 2:1 rows), T<sub>4</sub> (wheat-mustard in 3:1 rows), T<sub>5</sub> (wheat-mustard in 4:1 rows), T<sub>6</sub> (wheat-mustard in 5:1 rows), T<sub>7</sub> (wheat-mustard in 2:2 rows), T<sub>8</sub> (wheat-mustard in 3:2 rows), T<sub>9</sub> (wheat-mustard in 4:2 rows) and T<sub>10</sub> (wheat-mustard in 5:2 rows). The experimental result indicatedthe significant variations of wheat yield by the wheatmustard intercropping system. The highest seed yield of wheat (3.4 t ha<sup>-1</sup>) was obtained from T<sub>1</sub> (sole wheat) that identical with T<sub>4</sub> (wheat-mustard in 3:1 rows) and similar with T<sub>9</sub> (wheat-mustard in 4:2 rows). Wheat yield gradually decreased with increasing mustard rows. The lowest seed yield (1.87 t ha-1) was obtained from T<sub>7</sub> (wheat-mustard in 2:2 rows) which was statistically similar to T<sub>8</sub> (wheat-mustard in 3:2 rows). The highest wheat equivalent yield (5.03 t ha<sup>-1</sup>) was obtained from T<sub>4</sub> (wheat-mustard in 3:1 rows). Treatment T<sub>4</sub> (wheat-mustard in 3:1 rows) produced the highest LER (1.45). Economic analysis of the different treatments showed that the highest gross return (Tk. 120250.0 ha<sup>- 1</sup>), the highest net return (Tk. 61178.0 ha<sup>-1</sup>) and BCR (2.04) from T<sub>4</sub> (wheat-mustard in 3:1 rows). Therefore, present study suggest that wheat and mustard intercropped in 3:1 rows showed the most compatible in respect of yield advantage and economic gain.</p> <p><em>Bangladesh Agron.
