Sowing Dates

A field experiment was carried out to determine the optimum sowing date and nitrogen (N) level for the scented rice cv. Pusa Sugandh-3. Twelve treatment combinations of 3 sowing dates, viz., 15th, 16th and 18th standard meteorological week (SMW) at an interval of 10 days and 4 nitrogen levels (‘0’, ‘40’, ‘60’ and ‘80’ kg N ha-1) were tested randomized in split plot design with three replications. Significant highest plant height (98.56 cm), tillers m-2 (333.41), dry matter (98.38 q ha-1), panicles m-2 (310.05), spikelets panicle-1(130.25) and grains panicle-1 (98.55), grain yield (45.2 q ha-1), harvest index (41.20 %), head rice recovery (47.5 %) and B:C ratio (3.03) were recorded for the early sown 15th SMW crop. Among the different nitrogen levels tested significant highest plant height (98.12 cm), tillers m-2 (342.33) dry matter (100.68 q ha-1), panicles m-2 (321.83), spikelets panicle-1(132.83) grains panicle-1 (96.79), grain yield (48.0 q ha-1), harvest index (42.68 %), head rice recovery (44.54 %) and B:C ratio (3.38) were recorded with the application of 80 kg N ha-1.Therefore, the variety, Pusa Sugandh-3 should be sown earlier in season from 15th to 16th SMW and with nitrogen application of 60-80 kg N ha-1 for realizing economically higher grain yield and profit under the temperate climatic conditions of Kashmir valley.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to December 2013 in the aman season to investigate the effect of age of seedling and nitrogen rates in the nursery bed on growth, yield and yield components of BRRI dhan52. The experiment comprised of three ages of seedlings viz., 30, 35 and 40 day old and four nitrogen rate N1-N@50 kg ha-1, N2-N@75 kg ha-1, N3-N@100 kg ha-1, N4-N@125 kg ha-1. The experiment was laid out in a split plot design with three replications. Age of seedling showed significant differences for shoot weight, survivor, no. grains panicle-1, panicle length, grain yield and straw yield. The highest root weight (0.072 gm-2), plant height (108 cm), total tillers hill-1 (8.22), effective tillers hill-1 (7.03), non-effective tillers hill-1 (1.19), survivor (95.1%), grains panicle-1 (106.2), grain yield (5.57 t ha-1), straw yield (6.26 t ha-1) and harvest index (0.47%) were found by transplanting 40 day old seedlings. The highest shoot weight (0.53 gm-2), 1000 grain wt. (25.3g) was found by transplanting 35 day old seedlings and 30 day old seedlings produced highest sterile spikelets (28.9) and panicle length (23.8 cm). Nitrogen rate in the nursery showed significant differences for shoot weight, root weight, survivor, plant height, total tillers hill-1, effective tillers hill-1, non-effective tillers hill-1, panicle length, grains panicle-1, grain yield and straw yield. Application of 50 kg N ha-1 gave higher plant height (108 cm) and harvest index (0.47%). On the other hand, application of 75 kg N ha-1 produced highest non–effective tillers hill-1 (1.0), grains panicle-1 (100.7), 1000 grain weight (25.3 g) and harvest index (0.47%). Application of 100 kg N ha-1 gave highest total tillers hill-1 (7.85), effective tillers hill-1 (6.85), non–effective tillers hill-1 (1.0), survivor (90.5%) and grain yield (5.01 t ha-1). Application of 125 kg N ha-1 gave highest panicle length (23.75 cm), grains panicle-1 (100.7), non–effective tillers hill-1 (1.0) and sterile spikelets (30.1). Forty day old seedlings grown with 100 kg N ha-1 at nursery found to be better in respect of grain yield. The result of the experiment also showed that aged seedlings regenerated quickly after desubmerge of water.Res. Agric., Livest. Fish.2(2): 261-269, August 2015

The present study was undertaken to study the extent of genetic variability, character association and path analysis in 53 irrigated late duration breeding lines for 12 quantitative and 10 quality parameters. Analysis of variance revealed the presence of significant variation among the breeding lines for all the characters except for total tillers per plant, effective tillers per plant, spikelet fertility percentage and grain yield per plant. The highest magnitude of PCV and GCV were displayed by grain yield per plant followed by harvest index, filled spikelet per panicle and 1000 seed weight. The greater extent of heritability in broad sense were recorded for days to maturity, days to 50% flowering, 1000 seed weight, plant height, total spikelet per panicle, kernel length, kernel L:B ratio, grain length, head rice recovery percentage, amylose content, hulling and milling percentage. However, high heritability coupled with high genetic advance as percent of mean were displayed by plant height, number of spikelet per panicle, filled spikelet per panicle,1000 seed weight, kernel length, kernel L:B ratio, grain length, head rice recovery percentage and amylose content. Grain yield per plant exhibited positive significant correlation with harvest index, effective tillers per plant, 1000 seed weight, spikelet fertility %, days to maturity and days to 50% flowering. Path analysis revealed direct effect on grain yield were exerted by days to 50% flowering followed by harvest index, 1000 seed weight, total tillers per plant, number of spikelet per plant, effective tillers per plant and plant height indicating their importance in rice breeding programs.

 An experiment was conducted during winter, 2010/11 at IAAS, Lamjung with the objective of studying effect of seed priming and nitrogen levels on yield and yield attributing characters of buckwheat. Altogether, there were 9 treatments of seed priming hours (0, 18 and 36) combined with nitrogen levels (30, 45 and 60 kg/ha). The experiment was laid out in randomized complete block design and each treatment was replicated thrice. The seed priming of 36 hours had resulted in significantly higher germination percentage in both 15 days after sowing (DAS) (4.40%) and 30 (DAS) (5.74%) The total germination percentage was also significantly higher (48.4%) with 36 hr seed priming. The main and interaction effects of seed priming and nitrogen levels had significant influence on days to 50% flowering. The dry biomass per plant, grain yield, straw yield, harvest index and percentage moisture content of biomass at harvest were found non-significantly different due to seed priming and nitrogen levels. The highest value for dry matter accumulation per plant (5.24 gm/plant), straw yield (8706 kg/ha) and % moisture content (71.0%) was recorded with 36 hr seed priming whereas the highest value for grain yield (1599 kg/ha), and harvest index (19.8) was obtained with 18 hr seed priming. Likewise, dry matter accumulation (5.38 gm/plant), grain yield (1575 kg/ha) and harvest index (22.0) was found highest in 45 kg N/ha. Similarly, the straw yield (9153 kg/ha) and % moisture content (75.3%) was found highest in the treatment with 60 kg N/ha. The interaction effect between nitrogen level and priming was found non-significant and the highest grain yield (2091 kg/ha) was obtained from 18 hr seed priming with 45 kg N/ha. Phosphorus consumption rate was intrestingly higher in buckwheat plot with nitrogen application. Moderate consumption of potassium was also observed while nitrogen content in soil remain apparantly unchanged and similar was the case with soil pH and organic matter content. Application of phosphatic fertilizer would be benefitial for buckwheat cultivation. Further experiment should be done to verify the effective dose of fertilizer.Journal of the Institute of Agriculture and Animal Science. Vol. 33-34, 2015, Page: 47-54

A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during November 2012 to March 2013 to evaluate the response of three (3) wheat varieties viz., BARI Gom23, BARI Gom24 and BARI Gom25 under four levels of nitrogen fertilizer i.e, 75, 100, 125 and 150 kg N ha-1. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Results showed that plant height, number of leaves plant-1, leaf length and dry matter content were significantly affected due to varieties and/or nitrogen levels. Grains ear-1, number of fertile grains plant-1, 1000-grain weight, grain yield and harvest index were also significantly influenced by varieties and/or nitrogen levels. The value of all parameters studied in this experiment increased with increasing nitrogen levels up to 125 kg N ha-1 and thereafter decreased with fertilizer increasing level. Combination results showed that BARI Gom-24 with application of 125 kg N ha-1 gave the maximum grain yield (4.71 t ha-1), harvest index (49.37 %) and protein content (10.88%).Bangladesh Agron.

This study was carried out at the experiment field, Kalar Technical Institute, Garmian Region in two growing seasons of 2016-2017 and 2017-2018 in order to evaluate the growth and yield potentials of barley under water stressed using hybrids as a source of wide range of genotypic variations. Therefore, five F2 barley hybrids (Hordeum vulgare L.) were screened for grain yield, biomass dry matter, plant height and harvest index under irrigated and drought conditions. Results showed that there was no effect of drought on grain yield (P>0.05) in 2017, while significantly reduced yield in 2018 and across-year mean (P-2 (3//14) under irrigated condition, and 267.8 (3//5) to 302.3 g m-2 (3//4) under unirrigated condition (P=0.001), biomass dry matter was ranged from 1099.1 (3//1) to 1370.5 g m-2 (3//14) under irrigated condition, and 892.6 (3//1) to 1153.9 g m-2 (3//14) under unirrigated condition (P=0.05), and harvest index were from 25.1 (3//14) to 28.0 (3//1) under irrigated conditions, and 25.9 (3//14) to 31.2 (3//1) under unirrigated conditions (P=0.04). Regression analysis, averaging over years, showed a positive relationship between grain yield and biomass under irrigated (R2=0.76; P=0.05), despite that, any positive relation was not found under unirrigated conditions (R2=0.43; P=0.23) due to post-anthesis drought stress. A strong relationship was also found between plant height and biomass dry matter under both irrigated (R2=0.89; P=0.02) and unirrigated (R2=0.97; P=0.003) conditions due to the high contribution of plant height in increasing plant biomass. It is concluded that genotypes had different response to drought due to their genetic diversity, and relatively low impact of water stress was appeared on growth and grain yield of barley in this semi-arid region compared to worldwide expected range of yield reduction.

Abstract Background: Soil fertility decline in agricultural land is due to intensive cropping system, shortening of the fallow period, reduced manure application, extensive use of crop residues as fuel or fodder and removal of ground cover. This study investigated the effect of biochar (BC), lime and farmyard manure (FYM) on growth, yield and grain nutrient of wheat on croplands at two sites in the southern Ethiopia.Result: Site significantly (P<0.05) influenced most growth parameters, yield and yield components, and grain nutrient concentration of wheat. The effects of BC, lime, and FYM were significant (p ≤ 0.001) on straw yield, grain yield, and total biomass. However, BC (5 t ha -1 ) produced the highest straw yield, grain yield and total biomass. The effects of BC, FYM and lime were significant (P < 0.001) on spike length and seed per spike. Similarly, BC and lime significantly (P < 0.001) affected plant height, number of total and productive tillers. BC (5 t ha -1 ) gave the highest plant height, total tillers and productive tillers, maximum number of seeds per spike,while FYM (10 t ha -1 ) produced the highest spike length. Biochar, FYM and lime significantly (p ≤0.001) affected thousand seed weight, but only BC had significant(p ≤0.001) effect on harvest index. Biochar (5 t ha -1 )and FYM (10 t ha -1 )produced the highest heaver thousand seed weight and the highest harvest index. Biochar significantly (P < 0.05) increased the concentrations of P and K of wheat grain. On the other hand, the highest effect on grain Ca concentration was from the application of lime while the highest effect on grain N concentration was from the application FYM (10 t ha -1 ).Conclusion: The superior effect from BC was attributed to improvements in soil pH, CEC, nutrient availability and water retention. In general, the use of BC could be better option to soil amendment for wheat production on croplands of smallholder farmers.

Although bioclimatic conditions of the Saint Lawrence Lowlands are generally good enough to grow wheat for bread, management of this wheat production is poorly known in Quebec. Yields and total above-ground dry-matter biomass of three spring wheat (Triticum aestivum L.) cultivars (Max, Columbus and Katepwa) were measured in 1991 and 1992 under three management systems on a clay loam soil of the Saint Lawrence Lowlands. Reduced (50 kg N ha−1 and 375 plants m−2), conventional (100 kg N ha−1 and 375 plants m−2) and intensive (150 kg N ha−1 and 450 plants m−2) management systems were compared. In 1991, significant differences were observed among cultivars for four variables: stem weight, harvest index, tillers per square metre, and 1000-kernel weight. The management effect is less important than the cultivar effect. In 1992, significant differences among cultivars were observed for six of the nine variables measured, and seven of the nine variables measured differed with management. No significant cultivar × management interactions were observed in either year. Increasing input levels did not increase yield in 1991, probably because of the drier conditions. In the cooler and rainy growing season of 1992, intensive management increased wheat yield compared with that of reduced and conventional management. In both years, grain yield under reduced management was not significantly different from that under conventional management. Grain yield under intensive management was significantly higher than under reduced and conventional management in 1992 but not in 1991. The results of this study did not clearly show that intensive management was really better in the climatic conditions of the Saint Lawrence Lowlands than conventional or reduced management.
