A comparative agronomical trial was conducted to know the effect of two different soil types on growth and production performance of BLRI Napier-4 fodder production at BLRI regional station, Baghabari, Shahzadpur, Sirajganj. Soil components are the determinant factors for growing any crops or fodders. Soil samples from sandy soil and normal soil (loamy) were analazed for soil pH, nitrogen, organic matter, salinity, Ca, K, S, Zn, Pb, Co, Mg, Fe etc. at the Central Laboratory of Soil Resource Development Institute (SRDI), Dhaka. Data were recorded on plant height, stem length, leaf length, number of leaf per stem, number of till per hill, yield per hill and total biomass yield per plot. Plant height, stem length and leaf length produced in normal soil were significantly higher (p<0.001) than those produced in sandy soil. Irrespective of soil type, the plant height, stem length, leaf length, yield per hill and biomass yield per plot produced in second harvest were significantly higher (p<0.001) than those produced in first harvest. But, number of leaf per stem and number of till per hill did not differ significantly (p>0.05) between two cuttings. It can be concluded from the present findings that BLRI Napier-4 cultivar may be produced in the sandy soil.Asian J. Med. Biol. Res. June 2017, 3(2): 182-185

The experiment was conducted at Bajar Para bathan of Shajadpur upazila under Sirajgonj district to study the effects of intercropping on high yielding fodder production in Bathan areas of Sirajgonj district. In this experiment, fodders were cultivated in 27 experimental plots of each size (15×15m) were arranged in 9 treatments as Khesari (Sole), Napier dwarf early, Napier dwarf late, Splendida, Jumboo, Khesari+Napier dwarf early, Khesari+Napier dwarf late, Khesari+Splendida and Khesari+Jumboo. The biomass yield of Napier dwarf early, Napier dwarf late, Splendida and Jumboo as sole crop were 100.32, 90.26, 72.31 and 48.33 ton/ha., respectively. The yield of Khesari was 58.76 ton/ha. as sole crop and differs significantly (p<0.01) when intercropped with Napier dwarf early, Napier dwarf late, Splendida and Jumbo. The fresh total biomass yield of intercropped high yielding fodders and Khesari was considerably higher (151.11 ton/h) compared to sole high yielding fodders (100.32 ton/h) and sole Khesari (58.76t/h). The total highest biomass yield (151.11 ton/ha.) was obtained from the combination of Napier dwarf early and Khesari intercropping, followed by Napier dwarf late and Khesari (134.63ton/ha.), Splendida and Khesari (115.73 ton/ha.) then Jumboo and Khesari (87.55 ton/ha.), respectively. The total biomass yield difference among the intercropped group was significant (p<0.05). The land equivalent ratio (LER) increased in the intercropped practices of Khesari+Napier dwarf early, Khesari+Napier dwarf late, Khesari+Splendida and Khesari+ Jumboo (1.84, 1.75, 1.73 and 1.65, respectively) compared with sole Napier dwarf early, Napier dwarf late, Splendida, Jumboo and Khesari. Benefit cost ratio (BCR) of Khesari+Napier dwarf early cropping method was 1.73 which was higher than others cropping method. It may be suggested to cultivate Napier dwarf early along with Khesari in the bathan land in the existing feeding system.DOI: http://dx.doi.org/10.3329/bjas.v44i1.23124          Bang. J. Anim.

Digesting animal manure anaerobically before applying it as fertilizer may be affected crop production differently compared to non-digested particularly in desert soils. A pot experiment was carried out to evaluate three non-digested (NDM) and digested (DM) farmyard manures (cattle, poultry, and sheep) and their combinations with urea on the wheat crop cultivated in desert soil. Fertilizers were applied at rates corresponding to 50, 150 and 250 kg Tot N ha<sup>-1</sup>. During the growing period, seed germination percentage (SGP), plant height, plant tillering percentage (PTP) and deficiency symptoms were assessed. Furthermore, total biomass yield and relative yields of ear, straw and root fractions were measured at harvest. Results showed that high application of DM reduced SGP significantly (p&lt;0.05), especially at the combination with urea. PTP was higher in non-digested manure treatments of sheep and poultry than DM, and also higher in digested cattle manure treatments than NDM, while it was zero in all urea treatments and control. Deficiency symptoms were seen in the treatments of low application rate as well as in all urea treatments and control. Plant height and biomass yield generally increased in NDM and DM treatments compared with urea treatments and the control. Beneficial of DM was seen in cattle and poultry manure treatments where they significantly (p&lt;0.05) yielded higher root, ears, and total biomass compared to NDM. However, non-digested sheep and poultry manure yielded higher straw biomass than DM. The combination of non-digested and digested manure with urea gave the maximum biomass yield, especially in combination with digested poultry manure.

A field experiment was conducted in agricultural field in Al-Rumaitha, district 25 km north of Al-Muthanna city, during the agricultural season 2017/2018. The aim was to study the effect of spray of seaweed extract at 0, 1 and 2 g.l-1 on growth and yield of two varieties of wheat (Bhooth 22 and Eebaa 99). The experiment was applied according to split plot design with three replicates. The results showed that the increasing of the concentration of seaweed extract up to 2 g L-1 in spray solution led to increase some growth properties (plant height, leaf chlorophyll concentration, flag leaf area and spike length). In addition seaweed extract up to 2 g.l-1 lead to increase the number of spikes/m2, grain yield, and biological yield gave 31.85%, 39.05% and 39.79% respectively compared to the control treatment, while the concentration of seaweed extract up to 1 g.l-1 lead to increased 1 the number of grains per spike. The results revealed a difference in between the varieties in almost growth and reproductive traits. Bhooth 22 has the highest plant height, leaf chlorophyll concentration, spike length, and number of spikes/ m2, grain yield (5979 kg ha-1) and total biomass yield was and the highest biomass (13571 kg ha-1). The interaction between spraying of seaweed extract and varieties explained a significant effect on leaf chlorophyll concertation and biomass yield.

Miscanthus is a C4 herbaceous perennial species and it was chosen as a bioenergy crop due to high biomass yield. Miscanthus sinensis has many phenotypes which are adaptated to various environments in China. In this study, 421 accessions of M. sinensis were collected from 22 provinces, and the genetic polymorphisms amongst these germplasm collections were identified using 20 primer pairs designed against 10 each from eSSR and gSSR transferable markers from barley. A total of 95 SSR loci were detected producing a 100% polymorphic rate among these M. sinensis accessions. The gSSR markers showed a richer genetic polymorphism than eSSR markers. Based on the UPGMA clustering, there was a distinct sub-population separation in M. sinensis, which indicates that geographical differences and natural selection are the driving forces for genetic variation and evolution in the species. The 20 pairs of barley markers matched to 26 loci associated with date of heading, plant height, leaf weight, stem weight, leaf/stem ratio, and total biomass yield. Eleven marker loci were associated with the date of heading, 4 with plant height, 10 with leaf weight, 7 with stem weight, 3 with leaf/stem ratio, and 10 with biomass yield.

AbstractMedicinal plants represent a valuable commodity due to beneficial effects of their natural products on human health, prompting a need for finding a way to optimize/increase their production. In this study, a novel growing media with various perlite particle size and its mixture with peat moss was tested for hydroponic-based production of Echinacea purpurea medicinal plant under greenhouse conditions. The plant growth parameters such as plant height, total fresh leave weight, fresh root weight, total biomass, total chlorophyll, leaf area, and essential oil compositions were assessed. Perlite particle size in the growing media was varied from very coarse (more than 2 mm) to very fine (less than 0.5 mm), and the ratio between perlite and peat moss varied from 50:50 v/v to 30:70 v/v. In addition, two nitrate (NO3−) to ammonium (NH4+) ratios (90:10 and 70:30) were tested for each growing media. The medium containing very fine-grade perlite and 50:50 v/v perlite to peat moss ratio was found to be most optimal and beneficial for E. purpurea performance, resulting in maximal plant height, fresh and dry weight, leaf surface area, and chlorophyll content. It was also found that an increase in NO3−/NH4+ ratio caused a significant increase in plant growth parameters and increase the plant essential oil content. The major terpene hydrocarbons found in extract of E. purpurea with the best growth parameters were germacrene D (51%), myrcene (15%), α-pinene (12%), β-caryophyllene (11%), and 1-Pentadecene (4.4%), respectively. The percentages of these terpene hydrocarbons were increased by increasing of NO3−/NH4+ ratio. It can be concluded that decreasing the perlite particle size and increasing the NO3−/NH4+ ratio increased the plant growth parameters and essential oil compositions in E. purpurea.

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.

Paspalum nicorae Parodi is a perennial, apomictic tetraploid forage species, native in the state of Rio Grande do Sul, Brazil, with grazing tolerance and adapted to sandy soils and moderate droughts. As a first step to future breeding, a morphological characterization regarding leaf hairiness, sheath, leaf and central venation color, growing habit, plant height, raceme number and length, and leaf length and width was performed in 53 accessions from Rio Grande do Sul that are part of a Paspalum species breeding program. 35.84% of the accessions had completely hairy leaves, 73.58% had green sheath, 54.71% whitish central venation, 50.94% decumbent habit. Leaf color was estimated by two methods, color chart and colorimeter. The accessions were classified as 76.92% green, 13.45% greenish yellow and 9.62% as grayish green by the first, and 59.62% grayish, 32.69% grayish yellow, 5.77% yellow and 1.92% dark grayish by the second method. Raceme length ranged from 9.40 to 1.30 cm, number of racemes from one to six (48.73% of the accessions had four racemes), leaf length and width from 36.13 to 13.06 cm and 0.67 to 0.36 cm, respectively, and plant height from 115.70 to 29.00 cm. Therefore, a large morphological variation among accessions was detected, with no relation to geographical location but indicating a high potential use in plant breeding programs.

Panicum virgatum could produce cattle feed with lower costs due to the low input requirements and its perennial nature. Dry biomass yield vs. N-P-K nutrient uptake relations as well as the N-mineralization and the N-fertilization recovery fraction for Panicum virgatum (cv. Alamo) were determined under field conditions for four N-fertilization (0, 80, 160 and 240 kg ha-1) and two irrigation levels (0 and 250 mm), οn two soils in central Greece with rather different moisture status. It was found that the dry fodder yield on the aquic soil may reach 14 t ha-1 using supplemental irrigation; while on the xeric soil a lower yield of 9-10 t ha-1 may be produced only under supplemental irrigation. Moreover, the average N, P and K concentration was 1.3%, 0.14% and 1.3% in leaves, and 0.5%, 0.85%, and 1.5% in stems, respectively, showing the very low crop requirements. Furthermore, linear biomass yield-nutrient uptake relationships were found with high R2, pointing to nutrient use efficiency of 132 and 75 kg kg-1, for N and K respectively. The base N-uptake ranged from 71-74 kg ha-1 on the aquic to 60 kg ha-1 or less on the xeric soil. Finally, it was found that N-recovery fraction was 20% on the aquic soil and lower on the xeric. Therefore, it could be conclude that Panicum virgatum seems to be a very promising crop for fodder production and its introduction in land use systems (especially οn aquic soils of similar environments) should be taken into consideration.

The experiment was conducted to study the comparison on biomass production of fodder germplasm. Para (Brachiaria mutica Stapf.), German (Echinochloa crusgalli L.) and Dhal (Hymenachne pseudointerrupta C. Muell) grasses were cultivated in a completely randomized design (CRD). The whole area was divided into nine plots. The area of each unit plot was 6 m x 6 m. Number of cuttings were 16,000 /hectare where Plant to Plant distance was 16 cm and row and raw distance was 16 cm. Equal amount of organic and chemical fertilizer were applied in all cutting. The fodders were first harvested after 60 days of planting, second and third after successive 60 days of re-growth. The findings of the study showed that fresh biomass (p<0.01) and dry biomass yield (p<0.05) of three fodder germplasm differed significantly. Crude protein and organic matter yield were significant (p<0.01) only in the second cutting. German grass was showed significantly higher in CP and OM yield (p<0.01) at second cutting than other grasses. However, no significant effect on plant height was observed among three grasses. From the above findings it may be concluded that among the three fodder germplasm, German fodder showed best result in respect of biomass production.
