A field experiment was conducted during kharif season of 2019 at Agronomy Main Research Farm, Odisha University of Agriculture and Technology, Bhubaneswar to study the effect of establishment methods and nutrient management on biochemical attributes, grain quality, yield parameters and yield of rice. The experiment comprised of two rice establishment methods, viz. direct seeded (DSR) and transplanted (TPR) and three nutrient management practices, viz. inorganic (soil test based fertilizer recommendation (STBFR), organic (1/3rd N through green manuring + 1/3rd N through neem oil cake + 1/3rd N through vermicompost) and integrated nutrient management (50% through STBFR + 50% through green manuring) laid out in a randomised block design with three replications. The results indicated that the concentration of chlorophyll was maximum at vegetative and gradually decreased up to maturity stage. TPR recorded comparatively higher total chlorophyll content (2.91mg g-1), grain C (40.58%), H (6.98%), S (0.18%), C/N (36.54), panicles hill-1 (6.78), panicle weight hill-1 (27.05 g), 1000 grain weight (27.86 g), number of filled grains panicle-1 (176.60) with 18.3 % yield advantage over DSR. Among nutrient management, INM recorded higher S (0.17%), carbohydrate (17.82%), panicle numbers hill-1 (8.5), panicle weight hill-1 (30.19 g), 1000 grain weight (28.13 g), number of filled grains panicle-1 (187.89), grain yield (4.36 t ha-1) with harvest index (39.67%), where as maximum N (1.48%), C (41.58%), H (7.07%), S(0.18%), C/H (5.87) was obtained in inorganic with grain yield (3.78 t ha-1). Organic produced the highest chlorophyll total (2.72 mg g-1), C/N (37.89) and harvest index (36.72%) with minimum grain yield (3.74 t ha-1). Hence, organic in conjunction with chemical ferilisers under TPR not only enhances the growth and yield but also improvement of biochemical attributes and grain quality of rice in coastal Odisha.

The experiment was at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh–2202 during late Rabi season (December-March) of 2015. It was two factorial experiment (1) irrigation level and (2) nitrogen rate. Irrigation significantly influenced on yield and yield contributing characters except harvest index. The highest plant height (79.69cm), maximum number of total tillers plant-1 (4.725), number of grains spike-1 (40.61), spike length (11.80cm), 1000 grain weight (28.67g), grain yield (3.227 t ha-1), harvest index (41.26%) were obtained by mulching treatment. Nitrogen rate significantly influenced the yield and yield contributing characters. The highest plant height (80.37cm), maximum number of total tillers plant-1 (5.124), number of grains spike-1 (40.85), spike length (10.37cm), 1000 grain weight (31.86g), grain yield (3.792 t ha-1), harvest index (41.69%) were obtained by the application of 180 kg N ha-1. The combined effect of Irrigation and nitrogen significantly interacted on yield and yield contributing characters. The highest plant height (83.44cm), number of total tillers plant-1 (5.66), number of grains spike-1 (41.60), 1000 grain weight (36.66g), grain yield (4.32 t ha-1) and harvest index (47.36%) were obtained by application of 180 kg N ha-1 with mulching. The present study revealed that high dose of nitrogen 180 kg ha-1 and mulching practice can compensate low production of wheat even at late sowing. Progressive Agriculture 29 (3): 213-220, 2018

The forty four promising sorghum genotypes were evaluated for variability, correlation and path analysis for yield and yield contributing characters, at Sorghum improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri during Rabi-2019-20. High estimates of PCV and GCV were observed for traits no. of green leaves per plant at harvest, panicle length (cm), panicle width (cm), panicle weight (g), harvest index and grain yield per plant (g).High estimates of heritability along with high genetic advance were recorded for plant height (cm), no. of green leaves per plant at harvest, panicle length (cm), panicle width (cm), panicle weight (g), 1000 grain weight (g), dry fodder yield per plant (g), harvest index and grain yield per plant (g).Correlation studies revealed a positive and significant association of grain yield with plant height (cm), number of internodes per plant, number of green leaves per plant at harvest, panicle length (cm), panicle width (cm), panicle weight (g), 1000 grain weight (g), dry fodder yield per plant (g) and harvest index at both genotypic and phenotypic level. Harvest index, panicle weight, dry fodder yield per plant, days to maturity and no. of internodes per plant recorded high magnitudes of direct effects accompanied by highly significant correlation with the grain yield at genotypic level, indicating true and perfect relationship between them. Thus suggesting that selection for these traits viz., harvest index, panicle weight, dry fodder yield per plant, days to maturity and no. of internodes per plant will be highly rewarding for improving the grain yield per plant.

Genetic variability, heritability, genetic advance and correlation coefficients were studied in 104 genotypes of wheat genotypes for yield and yield contributing traits. Both GCV and PCV were found to be moderate for flag leaf area, biological yield per plant, grain yield per plant and ash content. The days to ear emergence, days to maturity, plant height, harvest index and 1000-grain weight low GCV and PCV values were observed. Number of productive tillers per plant and spike length recorded moderate value of PCV and low value of GCV. High estimate of heritability in narrow sense was recorded for number of productive tillers per plant, biological yield per plant, harvest index and grain yield per plant, while it was moderate for days to ear emergence, days to maturity, plant height, flag leaf area, spike length, grains per spike and low heritability were recorded for 1000-grain weight. High heritability coupled with high genetic advance in per cent of mean was recorded for biological yield per plant and grain yield per plant. Grain yield per plant exhibited highly significant and positive association with 1000-grain weight, harvest index, biological yield per plant, grains per spike, number of productive tillers per plant and days to maturity.

The experiment was conducted with 60 genotypes of bread wheat. These genotypes were grown in RBD using three replications during Rabi 2016-17 at Research Area of Wheat and Barley Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar. To study the variability, correlation and path analysis, data were recorded for yield and its component traits i.e. days to 50% heading, days to anthesis, grain growth rate at 14, 21, 28 days (mg/g/day), plant height (cm), number of effective tillers/meter, flag leaf length (cm), flag leaf width (cm), flag leaf area (cm2), spike length (cm), number of spikelets per spike, number of grains per spike, 1000 grain weight (g), grain yield per plot (g), biological yield/plot (g) and harvest index (%). ANOVA showed highly significant differences among the genotypes for all the traits indicating adequacy of material and the traits studied for further assessment of genetic variability parameters. High value of GCV and PCV was recorded for grain yield per plot, followed by biological yield, indicating greater amount of variability among the genotypes. Highest heritability was recorded for days to 50% heading, followed by days to anthesis. Highly significant and positive association was perceived between grain yield and tillers per meter, plant height, number of grains per spike, number of spikelets per spike, flag leaf area, grain growth rate at 14, 21 and 28 days after anthesis, spike length, 1000 grain weight, biological yield and harvest index. The high direct effects were recorded for biological yield, harvest index, flag leaf breadth, number of effective tillers per meter and 1000 grain weight, in order.

<span>Forty nine genotypes of wheat were evaluated for 12 quantitative and one quality traits during 2010-11. The experiment was conducted in randomized complete block design with three replications at Crop Research Centre, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The mean, range, genotypic and phenotypic coefficient of variation, heritability in broad sense, genetic advance correlation and path analysis were analyzed. Plant height, number of productive tillers per plant, spike length, 1000-grain weight, biological yield per plant and harvest index were significant and positive correlated with grain yield per plant. The phenotypic and genotypic path coefficients exhibited high positive direct contribution of number of productive tillers per plant, plant height, harvest index and 1000-grain weight towards grain yield.The positive indirect effect of plant height on grain yield was registered via days to maturity, number of spikelets per spike, 1000-grain weight and biological yield per plant. Number of productive tillers per plant revealed contribution on grain yield via number of grains per spike, 1000 grain weight, biological yield per plant and harvest index revealing that indirect selection of these characters would be effective in improving grain yield per plant. Higher genotypic coefficient of variance along with high heritability and genetic advance for grain yield per plant, plant height, number of spikelets per spike, number of grains per spike and 1000-grain weight would also be of great use for indirect selection for improvement in yield per plant. </span>

Three field trials were established at Tamworth in northern New South Wales to quantify the effect of stripe rust on the yield of wheat. The yield parameters were total grain yield per plot, 1000-grain weight, number of grain produced per head. tiller number and grain yield per plant. In addition, grain protein and dough and flour quality were determined. The total yield losses were found to be dependent on the cultivar, the timing of the epidemic and the yield potential of the crop. In most cases, early stripe rust epidemics had a greater effect on yield than late epidemics. Total grain yield and 1000-grain weight were most often affected. Long season epidemics affected all the yield parameters, with losses of up to 50% in grain yield being recorded in susceptible cultivars. The quality of dough and flour was unaffected by the fungicide treatments. The results suggest that the levels of resistance of the currently recommended wheat cultivars were sufficient to protect them from yield losses from stripe rust epidemics in most years.

1000 Grain Weight

Twenty-eight Australian wheat (Triticum aestivum L. em. Thell.) cultivars representing a series from the 1860s to 1982, were grown in 20 field trials over four years in the wheatbelt of Western Australia. The cultivars included introductions and selections made before 1900, plus important cultivars bred or grown in Western Australia up to 1982. Five of the latter group were from crosses including semidwarf cultivars as parents. Grain yields were measured on all trials, and six trials were also sampled for biomass and yield components.Based on the regression of mean grain yield versus the number of years elapsed since 1884, yields have increased from 1022 kg ha-1 in 1884 to 1588 kg ha-1 in 1982. This represents a rate of increase of 5.8 kg ha-1 year-1 or 0.57% per year. Regression of cultivar yield on site mean yield gave values of b, the slope of the regression, from 0.66 to 1.24, and these were higher for modern than for old cultivars.In six trials sampled for yield components, above-ground biomass appeared to have increased slightly when comparing early selections and their derivatives with later cultivars, but over 80% of the overall increase in grain yield was due to increase in harvest index. Grains per car and grains m-2 were strongly and positively correlated with grain yield, but there were weak negative correlations between 1000-grain weight and yield, and between 1000 grain weight and years since 1884. Cultivars with a semi-dwarf background had equal biomass, but higher yield, harvest index, ear number m-2 and grains ear-2 than modern tall cultivars. The results show that genetic improvement has substantially increased yield potential in this environment and that this has been achieved through substantial increases in grain number m-2 associated with an improvement in harvest index.

A field experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the period from April to July 2012 to study the effect of variety and weeding regime on the yield components and yield of Aus rice. The experiment was laid out in a randomized complete block design with three replications. The experimental treatments comprised four varieties viz. BR 26, BRRI dhan27, BRRI dhan48 and Pariza; and five weeding treatments viz. no weeding, one hand weeding at 20 DAS(Days after sowing), two hand weeding at 20 DAS and 30 DAS, three hand weeding at 20, 30 and 40 DAS and weed free. Here broadcasting method of planting was used. Results revealed that varieties had significant effect on plant height, number of total tillers hill-1, number of effective tillers hill-1, number of non-effective tillers hill-1, number of grains panicle-1, number of unfilled spikelets panicle-1, 1000-grain weight, grain yield, straw yield, biological yield and harvest index. Grain yield was the highest in BRRI dhan48. Weeding regime had also significant effect on all the studied crop parameters except 1000-grain weight. The highest grain yield was obtained from weed free condition followed by three, two and one weeding conditions. Interaction between variety and weeding regime significantly influenced all the studied crop parameters except 1000-grain weight and harvest index. In interaction it was observed that the highest grain yield was obtained from BRRI dhan48 under two weeding condition. DOI: http://dx.doi.org/10.3329/jbau.v11i1.18198 J. Bangladesh Agril.

The present investigation was carried out during 2011-12 in a randomized block design (RBD) with 35 diverse wheat genotypes to assess the genetic diversity for various morphological and quality traits. The analysis of variance for grain yield and its contributing components namely days to 50% flowering, days to maturity, productive tillers, plant height, spike length, spikelets pet spike, grains per spikelet, biological yield, harvest index, 1000 grain weight, grain yield and gluten content showed highly significant differences (at <1% level of significance) among the genotypes under present study. High heritability along with high genetic advance and high phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) for grain yield (g), biological yield (g), harvest index (%), spike length (cm) and 1000 grain weight (g) indicated substantial contribution of additive gene action in the expression and thus selection would be effective for genetic improvement of these traits for improving grain yield in wheat. On the basis of multivariate analysis, 35 genotypes were grouped into ‘6’ clusters based on genetic divergence (D2 ) value. The compositions of clusters revealed that the Cluster IV contained the highest number of genotypes (9) followed by Cluster II (8), Cluster VI (8) and Cluster III (7). The highest inter cluster values were recorded between cluster III and V (8357.19) followed by cluster IV and V (7513.88), cluster IV and VI (6009.44) and cluster III and VI (5530.40) exhibiting wide genetic diversity. Among different traits, biological yield (32.12%), productive tillers (28.74%), harvest index (26.71%), plant height (24.20%), grain yield (19.23%) and grains per spikelets (14.89%) had maximum contribution to total genetic divergence, therefore may be used as selection parameters in transgressive segregants. Selection of genotypes from the clusters may be used as potential donors for further hybridization programme to develop genotypes with high yield potential in wheat crop.
