An experiment was carried out at the research field of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur during January 2017 to May 2017 to evaluate the effects of poultry litter based composts on morpho-physiological, yield and yield contributing characters of BRRI dhan28, a mega rice variety of Boro season in Bangladesh, under different water stress conditions. The plants were grown in pots, and the experiment was laid out in a factorial complete randomized design (CRD) with three replications. Factor A included three levels of fertilizer and compost amendments i.e. control (recommended inorganic fertilizer), compost (10 t ha-1) + inorganic fertilizer, compost (20 t ha-1) + without inorganic fertilizers, and factor B comprised of three water levels (continuous flooding, 100% field capacity and 75% field capacity). Different parameters such as plant height, tiller number, leaf number, leaf area, chlorophyll content, proline content and yield contributing characters were measured during the experiment. Most of the measured parameters were significantly influenced by irrigation levels with different fertilizer and compost amendments. The highest plant height and leaf number per hill were found in the treatment of compost (10 t ha-1) + inorganic fertilizer with 100% field capacity, though the maximum tiller number were produced by the interaction of control with flooding irrigation. The total chlorophyll was observed more in flag leaf by the interaction of control with 100% field capacity. The Proline content was observed more in flag leaf by the interaction of control with 75% field capacity. Relative water content was found more with the interaction of compost (10 t ha-1) + inorganic fertilizer with 75% field capacity. The highest effective tiller number hill-1 was found from control (19.33) at harvest. It was also observed that irrigation with 75% field capacity produced the lowest effective tiller (15.89) hill-1 at harvest. The longest panicle length (23.12 cm) was observed with the combined effect of compost (10 t ha-1) +inorganic with 75% field capacity. Thousand grain weight was found highest (18.83 g) in the interaction of compost (20 t ha-1 + without inorganic) with 75% field capacity. The interaction of compost (20 t ha-1 + without inorganic) and flooding irrigation gave the highest grain yield (33.17 g pot-1), which was statistically similar to the treatment of compost (10 t ha-1 + inorganic) with flooding irrigation. The highest harvest index was found from compost (20 t ha-1 + without inorganic) with flooding irrigation. The Agriculturists 2020; 18(1) 42-55

An experiment was carried out at the Research Field of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur from July to November 2018. The study evaluated the effects of poultry litter based composts on morpho-physiological, yield and yield contributing characters of transplanted aman rice (var.Binadhan-7, BRRI dhan56, BRRI dhan66) and soil fertility. The experiment was laid out in a two factorial complete randomized design (CRD) with three replications. Factor A included three varieties (Binadhan-7: V1, BRRI dhan56: V2, and BRRI dhan66: V3) and factor B comprised of three fertilization levels viz. control (inorganic)-F1, poultry litter based compost 20 ton ha-1: F2, and 30 ton ha-1: F3. The performances of plant growth parameters such as plant height, tiller number, leaf number, leaf area, SPAD value, as well as yield and yield contributing parameters, and soil chemical properties were measured. Varieties and fertilizer levels significantly influenced most of the morphophysiological traits and yield and yield contributing characters. The tallest plant was recorded from V2 variety (BRRI dhan56). The highest leaf number hill-1 (80.89 at 30 DAT) was recorded from V3 (BRRI dhan66). The highest number of tiller was produced by the interaction of compost F2 (20 t ha-1) with V1 (Binadhan-7). The highest effective tiller number (13.67) hill-1wasrecorded from F2 (compost 20 t ha-1) with F1 (Binadhan-7) at maturity. The longest panicle (24.16 cm) was found in F1V1 (inorganic with Binadhan-7) treatment. The highest 1000-grain weight (23.57 g) was recorded from F3V3 treatment (compost-30 t ha-1 with BRRI dhan66). The maximum harvest index was recorded from F1 (inorganic) with BRRI dhan66. Soil fertility status increased with higher dose poultry litter based compost (30 t ha-1). Bangladesh Agron.

In this study, factorial randomized experiments were conducted in a controlled greenhouse environment to investigate an efficient and effective component of water management technology in increasing soybean yield. The soybeans were planted in polybags with 6 kg of Alfisol soil media and fertilizer. The bags were perforated with 16 holes at approximately 1 to 2 cm from the base and put into a water container. The container was immersed in water levels of 5 cm and 10 cm. The application of these immersions was carried out in four stages: 0 to 15 days after planting (DAP), 15 to 30 DAP, 30 to 45 DAP, and continued until harvest. Observations of growth were carried out on the greenness of leaves, plant height, leaf area, root length, and dry weight of plants, and soil water content was checked every two weeks. The yield measured after harvest consisted of the number of pods, the number of seeds/plants, weight of 100 seeds, and weight of seeds per plants. The water level had a significant effect on plant height, dry weight, leaf greenness, number of pods, and number of seeds/plants. The immersion stage has significant effects on plant height, harvest age, dry weight, leaf greenness, number of pods, and number of seeds/plants. Continuous immersion in a water level of 5 cm has shown the best yield on number of pods (20.81) and number of seeds per plant (162.94). This treatment increased seed yield (seed weight) approximately by 19.23% compared to the field capacity.

Drought And Heat Stress

Dual-purpose barley and wheat production is a valuable resource to fill feed gaps and grain production, but availability at drought and heat stress conditions is still not clearly studied.  Two experiments were conducted at semi-controlled green house to determine biomass production at vegetative stages, chlorophyll content and grain yield. Experiment 1 consists of four clipping treatments on wheat, i.e. one, two, three times clipping and un-clipping control. Experiment 2 combined two clipping treatments (one clipping and un-clipping) and two levels of water (low: 40 % of field capacity; normal: 85 % of field capacity) on barley. Wheat grain yield was severely affected by increasing clipping number under heat stress. Total biomass at one clipping was the same level as control treatment. Although physiological maturity was delayed 8 days from control to 3 times clipping application, biomass and yield remained below the control application due to shrinkage in plant height and other organs size. Clipping and water levels at barley significantly impacted biomass and plant height, but all traits were not related by interactions clipping x water level. The clipping application in heat stress reduced total biomass by 21.3 and 30.4 % in well-watered and dry conditions, respectively.  Contrary to what is expected, it seems clear to obtain satisfactory forage and grain yield by optimizing the management technique, growing in dual-purpose production in wheat and barley in warm environments.

A study on genetic variability, heritability and genetic advance for seed yield and component traits was made in 40 genotypes of riceduring kharif 2011-2012 at SHIATS, Allahabad. The analysis of variance showed highly significant differences among the treatments for all the 13 traits under study.The genotypes namely CN 1446-5-8-17-1-MLD4 and CR 2706 recorded highest mean performance for panicles per hill and grain yield. The highest genotypic and phenotypic variances (VG and VP) were recorded for spikelets per panicle (3595.78 and 3642.41) followed by biological yield (355.72 and 360.62) and plant height (231.48 and 234.35).High heritability (broad sense) coupled with high genetic advance was observed for plant height, flag leaf length, panicles per hill, tillers per hill, days to maturity, spikelet’s per panicle, biological yield, harvest index, 1000 grain weight and grain yield, indicating that selection will be effective based on these traits because they were under the influence of additive and additive x additive type of gene action. Highest coefficient of variation (PCV and GCV) was recorded for tillers per hill (18.42% and 17.23%), panicle per hill (19.76 % and 18.68%), spikelet’s per panicle (34.30 and34.07 %), biological yield (28.31 % and 28.12 %), 1000 grain weight (15.57 % and 15 31 %) and grain yield (46.66% and 23.54 %), indicating that these traits are under the major influence of genetic control, therefore the above mentioned traits contributed maximum to higher grain yield compared to other traits, indicating grain yield improvement through the associated traits.

Architectural Traits

AbstractWheat is a major food crop worldwide. The plant architecture is a complex trait mostly influenced by plant height, tiller number, and leaf morphology. Plant height plays a crucial role in lodging and thus affects yield and grain quality. In this study, a wheat population was genotyped by using Illumina iSelect 90K single nucleotide polymorphism (SNP) assay and finally 22,905 high-quality SNPs were used to perform a genome-wide association study (GWAS) for plant architectural traits employing four multi-locus GWAS (ML-GWAS) and three single-locus GWAS (SL-GWAS) models. As a result, 174 and 97 significant SNPs controlling plant architectural traits were detected by ML-GWAS and SL-GWAS methods, respectively. Among these SNP makers, 43 SNPs were consistently detected, including seven across multiple environments and 36 across multiple methods. Interestingly, five SNPs (Kukri_c34553_89, RAC875_c8121_1490, wsnp_Ex_rep_c66315_64480362, Ku_c5191_340, and tplb0049a09_1302) consistently detected across multiple environments and methods, played a role in modulating both plant height and flag leaf length. Furthermore, candidate SNPs (BS00068592_51, Kukri_c4750_452 and BS00022127_51) constantly repeated in different years and methods associated with flag leaf width and number of tillers. We also detected several SNPs (Jagger_c6772_80, RAC875_c8121_1490, BS00089954_51, Excalibur_01167_1207, and Ku_c5191_340) having common associations with more than one trait across multiple environments. By further appraising these GWAS methods, the pLARmEB and FarmCPU models outperformed in SNP detection compared to the other ML-GWAS and SL-GWAS methods, respectively. Totally, 152 candidate genes were found to be likely involved in plant growth and development. These finding will be helpful for better understanding of the genetic mechanism of architectural traits in wheat.
