Scarcity of water resources in India is limiting the production of flooded rice crop. A field experiment was conducted in factorial RBD with sixteen treatment combinations including four rice varieties viz. V1: PR-115, V2: DRRH-3, V3: PAC-837 and V3: PR-121 and four fertility levels viz. F1: control (N0P0K0), F2: N, P2O5, K2O at 90: 45: 22.5 kg ha-1, F3: N, P2O5, K2O at 120:60:30 kg ha-1 and F4: N, P2O5, K2O at 150: 75: 37.5 kg ha-1 replicated thrice. The results revealed that among the different varieties, PAC-837 recorded highest plant height and number of tillers m-2 at all the growth stages. All yield attributes viz. number of effective tillers m-2, number of seeds per panicle, 1000-grain weight, spikelet sterility and grain yield, straw yield and harvest index significantly differed in different varieties and were recorded highest in PAC-837 which were however, statistically at par with DRRH-3 except grain yield and effective tillers m-2. Rice variety PAC-837 recorded highest grain yield of 45.65 q ha-1 and straw yield of 59.98 q ha-1. Among the fertility levels, number of effective tillers m-2 significantly increased up to 120: 60: 30 N-P2O5-K2O kg ha-1 thereafter nonsignificant differences were noticed. The grain and straw yield increased up to 150: 75: 37.5 N-P2O5-K2O kg ha-1 and recoded grain yield of 52.78 q ha-1 and straw yield of 73.85 q ha-1 with application of 150:75:37.5 N-P2O5-K2O kg ha-1. Nutrient application of 150: 75: 37.5 N-P2O5-K2O kg ha-1 recorded highest available N (238.16 kg ha-1), P (16.18 kg ha-1) and K (163.25 kg ha-1) in soil after harvest of the crop. Higher available nitrogen (235.28 kg ha-1), phosphorus (16.38 kg ha-1) and potassium (154.24 kg ha-1) n soil were recorded with PR-121 and lowest available major nutrients were recorded with variety PAC-837. This study would help to introduction and adaptation of new rice variety PAC-837 with application of 150: 75: 37.5 N-P2O5-K2O kg ha-1 under aerobic conditions in Shiwalik foothills region of North-Western Himalayas.

An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh in transplant Aman season 2008 to find out the effect of urea super granules (USG), prilled urea (PU) and poultry manure (PM) on the yield and yield attributes of transplant Aman rice varieties. Two transplant Aman rice varieties viz. BRRI dhan41 and BRRI dhan46 and ten levels of integrated nutrient management encompassing USG, PU and PM were tested following randomized complete block design with three replications. It was observed that variety BRRI dhan41 gave higher grain yield than BRRI dhan46. For fertilizer effect, the highest grain yield (5.17 t ha-1) was obtained from full dose of USG (1.8g) and other inorganic fertilizers, which was similar to that obtained from full dose of USG (1.8g) + PM at 2.5 t ha-1 followed by full dose of PU + PM at 2.5 t ha-1. The lowest grain yield was obtained in the control treatment. In case of interactions, the highest grain yield was obtained in BRRI dhan41×1.8g USG and other inorganic fertilizers which was similar to that of the same dose of USG with PM at 2.5 t ha-1 and the lowest yield was obtained in the control treatment. It was assessed that a considerable portion (31.25%) of PU nitrogen could be saved by using USG (1.8g) together with other inorganic fertilizers or with PM at 2.5 t ha-1.

Transplanted (T.) aman rice is the major crop in the southwestern coastal region of Bangladesh where most of the fields remain fallow the rest of the year due to the cultivation of late-maturing and long-duration aman rice varieties with low yield potential. Timely transplanting of short-duration HYV varieties increased grain yield and allowed the field to be cleared earlier for the next crop. The experiment was conducted in the experimental field of Agrotechnology Discipline, Khulna University, Khulna during the monsoon (June to December) for  investigating the influence of transplanting dates on growth, yield attributes, and yield of Binadhan-7. The experiment was laid out in a randomized complete block design and replicated thrice. The experimental treatment comprised of ten transplanting dates (viz.,9 July, 16 July, 23 July, 30 July, 6 August, 13 August, 20 August, 27 August, 3 September, and 10 September) at 7 days intervals. Data recorded on different growth, yield, and yield contributing parameters were influenced substantially by the dates of transplanting. Results of this study showed that transplanting on 30 July produced the tallest plant (105.40 cm), highest tiller hill-1 (20.40), effective tillers hill-1 (17.30), panicle length (22.22 cm), number of grain panicle-1 (10.34), 1000 grain weight (22.83 g), grain yield (4.72 tha-1), straw yield (5.15 tha-1) and harvest index (47.85%) which were on parity with 6 August of transplanting. From the findings of this study, it can be concluded that from 30 July to 6 of August is optimum and recommended transplanting window for the short duration aman rice variety (Binadhan-7) in the coastal zone of southwestern Bangladesh. Furthermore, this transplanting window resulted in an early harvest and timely vacant the field for winter crop planting.

An experiment was conducted in the Agriculture Field Laboratory, Noakhali Science and Technology University (NSTU) to evaluate the effects of age of seedlings on the yield and growth performance of transplanted Aus (T. Aus) rice variety from April 2019 to July 2019. The experiment was carried out assigning four age of seedlings (T1 = 22-day old, T2 = 24-day old, T3 = 27-day old, T4 = 30-day old) and two rice varieties (V1 = BRRI dhan83, V2 = BRRI dhan65). The experiment was laid out in a Randomized Complete Block Design with three replications. In case of variety, the highest plant height (102.108 cm), the highest grain yield (2.643 t/ha), and the highest harvest index (32.317%) were obtained in BRRI dhan83 where the lowest plant height (87.804 cm), the lowest grain yield (2.431 t/ha) and the lowest harvest index (32.068%) were obtained in BRRRI dhan65. The age of seedlings had significantly affected total tillers/hill, effective tillers/hill, panicle length in T. Aus rice variety. The highest plant height (98.16 cm), straw yield (6.122 t/ha), the maximum number of effective tillers/hill (15.347) were obtained in 24 days old seedlings. The highest grain yield (2.634 t/ha) was obtained from 27 days old seedlings, and the highest harvest index (33.88%) was obtained from 22 days old seedlings. The lowest grain yield (2.429) was obtained from 24 days old seedlings, and the lowest panicle length (13.753 cm), harvest index (30.467%), and the minimum number of effective tillers/hill (13.753) were obtained from 30 days old seedlings. The lowest straw yield (5.075 t/ha) and plant height (93.16 cm) were obtained from 22 days old seedlings. In case of interaction, the highest plant height (104.667 cm) and the harvest index (34.86%) were observed in BRRI dhan83 at 27 days old seedlings. The highest straw yield (5.805 t/ha) was observed in BRRI dhan65 at 30 days old seedlings. The maximum number of effective tillers/hill (18.519) was observed in BRRI dhan83 at 24 days old seedlings. The highest grain yield (2.94 t/ha) was observed in BRRI dhan83 at 22 days old seedlings. The lowest plant height (80.67 cm) was observed in BRRI dhan65 at 27 days old seedlings. The minimum number of total tillers/hill (17.01) was observed in BRRI dhan83 at 22 days old seedlings; lowest panicle length (20.78 cm), the minimum number of grains/panicle (68.07) were observed in BRRI dhan65 at 24 days old seedlings; 1000 grains weight (22.76 g), the lowest grain yield (2.18 t/ha) were observed in BRRI dhan83 at 24 days old seedlings; the lowest straw yield (4.54 t/ha) was observed in BRRI dhan65 at 22 days seedlings old and lowest harvest index (29.09%) were observed in BRRI dhan65 at 30 days old seedlings. Based on the above results, it may be concluded that almost all of the yield and yield contributing characters of T. Aus rice performed best under the interaction between age of seedlings 22 days old seedlings and the variety BRRI dhan85.

Greater attention should be paid for increasing the yield per unit area by growing modern varieties of rice through improved cultivation practices. An experiment was conducted for investigating the effect of variety and date of harvesting on yield performance of modern rice varieties during Kharif, 2012 at Agricultural Research Station, Bapatla. The experiment was laid out in a split-plot design with three replications. Main treatments comprised of four rice varieties namely, BPT 5204, BPT 2270, BPT 2231, NLR 34449, NLR 28523 and MTU 1010 and sub treatments comprised of three time of harvesting viz., 25, 30 and 35 days after flowering. Plant growth, yield attributes, yield and quality of rice varieties were significantly influenced by different dates of harvesting. BPT 2270 was found significantly superior to all other varieties in respect of effective tillers, grains panicle-1, grain yield, straw yield and hulling per cent, milling per cent and head rice recovery. Among three harvesting times, the highest grain yield (6250 kg ha-1) and straw yield (7314 kg ha-1) were obtained when the crop was harvested at 30 days after flowering. The interaction effect of variety and date of harvesting was significant in respect of grain and straw yield. The highest grain yield (7771 kg ha-1) was observed in BPT 2270 when harvested at 30 days after flowering. Therefore, optimum date of harvesting for higher grain yield may be 30 days after flowering for avoiding immature stage as well as shattering loss.

An experiment was conducted at the net house of Department of Agronomy, Bangladesh Agricultural University, Mymensingh from July to December 2012to investigate the ameliorative effect of green manure and gypsum application on the yield of transplant Aman rice variety BRRI dhan40 under various levels salinity stress. Sodium chloride induced salinity was imposed at tillering stage of plant development. The levels of salinity were 0, 25 and 50 mM NaCl. Green manure @ 0, 5 and 10 t ha gypsum @ 0 and 1 g kg-1 and 1 soil were applied to ameliorate the salinity stress effect. 1 g kg-1 soil were applied to ameliorate the salinity stress effect. Results revealed that the different levels of salinity had significant adverse effect on plant height, number of tillers hill-1, number of effective tillers hill-1, number of ineffective tillers hill-1, 1000-grain weight, grain yield, biological yield and harvest index (HI). All the plants were affected badly when they were exposed to salinity level of 50 mM NaCl. Application of green manure and gypsum helped them ameiorate salinity either individually or in combination at all salinity levels. Grain yield reduction at 50 mM salinity level was 38.64% compared to control which was minimized to 19.04% by the application of green manure @ 10 t ha-1. Grain yield reduction was also minimized from 37.08% to 27% at the same level of salinity by the application of gypsum@ 1 g kg-1soil. Similar amelioration effect was also observed in case of straw yield. The amelioration was improved further when both green manure and gypsum were applied. Without any salinity stress grain yield was 4.49 t ha-1, which was reduced to 2.61 t ha-1 (41.87% reduction) when the crop was stressed with 50 mM salinity. Application of green manure @ 10 t ha-1 and gypsum @ 1 g kg-1 soil improved grain yield to 4.00 t ha-1, where yield reduction was just 10.91%. Similar improvement was also found in straw yield. The results of the study conclude that salinity stress in transplant Aman rice var. BRRI dhan40 could successfully be ameliorated through application of green manure@ 10 t ha-1 and gypsum@ 1 g kg-1 soil.Bangladesh Agron. J. 2014, 17(1): 1-10
