A field experiment was conducted at the Agronomy farm of Institute of Agriculture and Animal Science (IAAS), Rampur during winter season of 2014/2015 to find out the response of wheat varieties under different sowing dates. There was 9 treatments consisting three date of sowing (November 14, November29 and December 14) in main plot and three varieties namely Tillotama, Danfe and Vijay in sub-plot and were arranged in split plot design with three replications. The grain yield was significantly higher (3.09 tha-1) at November 14 whereas highest straw yield was recorded for November 29 sown wheat (5.61 t ha-1). Effective tiller (414) and number of grain per spike (34.34) were highest for November 29 sown wheat. The late sown wheat had more sterile floret (42.65%) while early sown wheat had highest thousand grain weight (51.23 g). Danfe had highest straw yield (5.87 t/ha). Effective tiller/m2 (419) and sterility percentage (43.35%) of Danfe was highest. Number of grains per spike (37.89) of Tillotama was highest and thousand grain weight (57.09 g) of Bijay was found highest. The grain yield of Bijay (3.30tha-1) was highest when it was sown at November 29. Int J Appl Sci Biotechnol, Vol 4(1): 27-31

Background: Wheat is an important food crop of world. This crop has the wider adaptability due to its genetic makeup. The sowing environment and varieties interaction plays important role to enhance its productivity and optimum utilization of the resources. As this crop has wider adaptability so we planned our experiment to study the grain yield, heat use and water use efficiency of diverse wheat varieties which have been recommended in different wheat growing zones, sown at different environment in North-western India, to increase the varietal spectrum.Methods: The field experiment was conducted in 2017-18 and 2018-19 at the research farm of the Punjab Agricultural University, Ludhiana, India. The experiment was conducted with four sowing dates (November 5, November 25, December 15 and January 5) in main plot and six wheat varieties (HS 562, HD 2967, HD 3086, HI 1544, MACS 6222 and WR 544) in sub-plot of split plot design with three replications. Result: The wheat crop sown on November 5 recorded the highest emergence count, plant height, heat use efficiency, normalized difference vegetative index, yield attributes, grain yield and water use efficiency than later sowing dates. Among the wheat varieties, HS 562 recommended for northern hill zone recorded heat use efficiency, helio-thermal use efficiency, at Leaf value, effective tillers, grains per earhead, grain yield and water use efficiency similar to HD 3086 recommended for North-western zone. The varieties recommended for other zones like HI 1544, MACS 6222 and WR 544 could not perform similar to the HD 3086.

This research was carried out to estimate the genetic parameters of fifty wheat genotypes received from the Agriculture Botany Division, Nepal Agriculture Research Council (NARC), Khumaltar, Lalitpur, in the winter season of 2014/2015 at Agriculture and Forestry University (AFU), Chitwan, Nepal. The experiment was performed in an alpha lattice design with two replications in five blocks in each replication and ten plots in each block. The analysis of variance showed highly significant differences among the genotypes for all the studied traits except spike length. This implies that, except for spike length, all other traits exhibited genetic variability. The phenotypic coefficient of variation (PCV) was generally higher than the genotypic coefficient of variation (GCV) for all characters. The difference between PCV and GCV was large in spike length followed by grain weight per spike, the number of grains per spike, grain yield, thousand-grain weight, and harvest index indicating that these traits are affected by the environment as well. Moderate to high heritability associated with a high genetic gain was observed for days to flag leaf appearance, panicle length, thousand-grain weight, grain yield, and harvest index indicating the involvement of additive gene action. Grain weight per spike, number of grains per spike, thousand-grain weight, biological yield, and harvest index were significantly correlated with grain yield indicating their important contribution to grain yield. WK 2525, WK 2437, and WK 2506 were three promising genotypes in terms of grain yield.

This study was conducted to evaluate the efficacy of different organic manure and inorganic fertilizer on the yield and yield attributes of Boro Rice (Oryza sativa L.). The experiment consisted of 8 treatments, T0: Control, T1: 100% N100P15K45S20 (Recommended dose), T2: 50% NPKS + 5 t cowdung ha-1, T3: 70% NPKS + 3 t cowdung ha-1, T4: 50% NPKS + 4 t poultry manure ha-1, T5: 70% NPKS + 2.4 t poultry manure ha-1, T6: 50% NPKS + 5 t vermicompost ha-1and T7: 70% NPKS + 3 t vermicompost ha-1. At 30, 50, 70, 90 DAT and at harvest stage the tallest plant (24.18, 31.34, 44.67, 67.05 and 89.00 cm) and the greatest number of total tiller per hill (5.43, 11.64, 21.01 and 17.90) at same DAT was recorded from T5 and the lowest was observed from T0 in every aspect. The maximum number of effective tillers per hill (13.52), the longest panicle (24.59 cm), maximum number of total grain per plant (97.45), the highest weight of 1000 seeds (21.80 g), the maximum grain yield (7.30 t ha-1) and straw yield (7.64 t ha-1) was recorded from T5 treatment whereas the lowest number of effective tillers per hill (6.07) , the shortest panicle (16.45 cm) , the minimum total grain per plant (69.13) , the lowest weight of 1000 seeds (16.73 g), the lowest grain yield (2.06 t ha-1) and straw yield (4.63 t ha-1) was observed from T0 treatment. Although the highest biological yield was recorded from T5 treatment but statistically similar result were found from T3, T4 and T7 treatments. The highest harvest index also recorded for T5 treatment. It was obvious that yield of rice can be increased substantially with the judicious application of organic manure with chemical fertilizer.

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during winter (Rabi) season of 2013-14 to evaluate the effect of integrated use of organic and inorganic fertilizers on the growth, yield and nitrogen (N) uptake of wheat. There were six treatments such as T0 (control), T1 [STB-CF (HYG)], T2 [STB-CF (HYG) + CD (5 t/ha)], T3 [STB-CF (HYG) +PM (3 t/ha)], T4 [STB-CF (HYG) COM (5 t/ha)] and T5 [FP (Farmers’ practice)]. The experiment was laid out in a Randomized Complete Block Design with four replications. Soil test based nitrogen, phosphorus, potassium, sulphur, zinc and boron were used @ 100, 20, 60, 10, 3 and 2 kg ha-1, respectively. The integrated use of organic and inorganic fertilizers significantly increased the yield attributes as well as grain and straw yields of wheat. The treatment T3 [STB-CF (HYG) + PM (3 tha-1)] produced the highest grain yield of 3554 kg ha-1 (69.67% increase over control) and straw yield of 3635 kg ha-1 (62.83% increase over control). The lowest grain yield (2094 kg ha-1) and straw yield (2232 kg ha-1) were found in control treatment. The N content and uptake by wheat were also markedly influenced by combined use of organic and inorganic fertilizers and the treatment T3 demonstrated superior performance to other treatments. So, the applications of fertilizers in combination with poultry manure @ 3 t ha-1 can be used for the successful cultivation of wheat in Old Brahmaputra Floodplain soil. Progressive Agriculture 27 (2): 149-153, 2016

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December 2004 to evaluate the effect of hill spacing on the performance of BRRI dhan40 and BRRI dhan41 as Transplant aman crop. The experiment consisted of five hill spacings viz., 5cm. 10cm, 15 cm, and 25 cm where row to row spacing of 25 cm was kept constant for all treatments. The experiment was laid out in randomized complete block design with four replications. The 25 cm x 5 cm hill spacing produced the tallest plant, highest total number of tillers/hill, bearing tillers/hill lowest number of non-hearing tillers/hill, grain yield and harvest index, while 25 cm x 5 cm hill spacing produced the highest number of sterile spikelets/panicle, straw yield and biological yield. BRRI dhan41 produced higher grain yield (4.7 t/ha) which was the contribution of higher number of grains/panicle and heavier grain weight. Lower yield (4.51 t/ha) was recorded in BRRI dhan40.Key Words: Varietal performance; T. aman rice; hill density.DOI: 10.3329/bjar.v34i1.5750Bangladesh J. Agril. Res. 34(1) : 33-39, March 2009

An experiment was conducted at the Agronomy Field of Patuakhali Science and Technology University, Dumki, Patuakhali from June to December, 2013 to find out the effect of variety and planting density on the yield and yield attributing characters of local aromatic rice. The experiment was laid out in a factorial randomized complete block design with three replications, which consisted of three local aromatic rice varieties (Chinigura, Shakhorkhora and Kalizira) and four planting densities were viz. S1 (25 cm × 20 cm), S2 (20 cm × 20 cm), S3 (20 cm × 15 cm) and S4 (20 cm × 10 cm). The results revealed that the local aromatic rice var. Shakhorkhora variety produced the highest number of grains per panicle (131) and 1000-grain weight (13.8 g), consequently higher grain (2.63 t ha-1), followed by Kalizira (2.56 t ha-1) and straw yield (4.21 t ha-1). One the other hand, higher number of tillers per hill (14.8), number of grains per panicle (140 nos.) were found in 20 cm × 20 cm spacing with higher grain yield.Bangladesh J. Agril.

A field experiment was done for two consecutive years from 2010-11 to 2011-12 with two varieties of wheat (DBW 17 and DPW 621-50) and ten treatments of fertilizer, involving NPK, FYM and micronutrient, with an objective to maximize the crop yield. Results showed that variety DBW 17 recorded significantly higher grain yield (4.93 %), straw yield (6.31%) and HI (1.12%) as compared to DPW 621-50. There was no significant difference in yield attributes between two varieties. Application of 150 % recommended NPK fertilizers produced the maximum grain yield (6.10 t ha-1), which was 7.7 % higher over the 100% NPK fertilizers, followed by 15 t ha-1 FYM application along with 150 (5.98 t ha-1) and 125 % (5.96 t ha-1) NPK application. There had no significant effect of micronutrients (Zn, Cu, Fe & Mn) on wheat yield indicating that the soil was not deficient in those micronutrients. A significant variation was observed between two years in respect of yield and yield attributes, higher performances being recorded in 2011-12. Crop lodging was observed, with a maximum lodging of 26.4 % causing a yield reduction of up to 9.9 %. Agronomic efficiency was the maximum (13.64 kg grain kg-1 fertilizer) with the recommended rate of fertilizers and it decreased with increasing rates. Addition of FYM didn’t increase the agronomic efficiency due to inclusion of 75 kg N contribution from 15 t ha-1 of FYM.SAARC J. Agri., 14(1): 103-110 (2016)

A field experiment was conducted at Kalikapur village of Kaliganj upazila under Satkhira district in order to observe the effects of flooding duration and additional application of K and S on transplanted boro rice cv. Binadhan-8 during January - May 2013. The experiment was laid out in a split-plot design where the main plots comprised of five flooding levels viz. continuous flooding (W1), flooding for 10 days (W2), flooding for 20 days (W3), flooding for 30 days (W4), flooding for 40 days (W5), and the sub-plots of four additional (over the recommended dose) nutrients rates viz. S43 + K25 (T1), K38 (T2), S32 + K38 (T3), and K50 (T4), with three replications. The duration of flooding showed significant positive effect on the yield and yield components of boro rice cv. Binadhan-8. The highest values for plant height (106.8 cm), panicle length (28.4 cm), number of plants hill-1 (15.3), grain yield (4.8 t ha-1) and straw yield (6.5 t ha-1) were recorded in continuous flooding (W1) while these values were decreased with the decrease in the duration of flooding from 40 days to 10 days. Additional application of K and S also significantly influenced all of the parameters. Results revealed that the highest values for plant height (102.8 cm), panicle length (26.6 cm), plants hill-1 (15.4), 1000-grain weight (23.9 g), grain yield (4.8 t ha-1) and straw yield (6.1t ha-1) were obtained from T3 where S and K were applied @ 32 and 38 Kg ha-1 in addition to the recommended fertilizer rate. The interaction of flooding and nutrients significantly manipulated the yield and yield attributes. Due to interaction of flooding and nutrients, the highest growth and yield was observed in continuous flooding with S32 + K38 (W1T3). The results indicated that the flooding with fresh water and use of additional nutrients (K and S) had a remarkable effect in growing boro rice cv. Binadhan-8 in saline soils of Bangladesh.Res.
