The parent males and females were maintained in cages for single-pair mating through selective breeding system for producing each generation. A total of 1118-day-old quail chicks comprising 4 types were hatched in one batch to produce eighth generation (G8). The expected genetic progress due to selection for 5th-week body weight was estimated for G8. The genotype had significant (p<0.001) effect on the body weight of quails at 5th week of age. The 5th-week body weight was 132.34±0.88, 123.91±0.52, 104.29±0.76 and 105.36±0.68g, respectively for D, W, Br, and Bl genotypes. The hatchability rate was significantly (p<0.001) higher in D (78.47%) compared to other three genotypes. The egg production percentage up to 24th week of age was 85.27±1.0, 80.22±1.61, 81.07±1.2 and 96.12±1.1, respectively for D, W, Br, and Bl and significantly (p<0.001) differed among all genotypes. Mortality percent among genotypes was statistically non-significant (p>0.05). Sixth-week body weight of males of D, W, Br, and Bl quails were expected to increase by 4.06, 6.36, 2.39, and 3.12g, respectively. While in females of D, W, Br, and Bl quails, the responses were 5.60, 3.61, 4.17, and 3.91g, respectively. Taken together, it may be concluded that Dhakai quail was superior for body weight and Black quail for egg production performance. These findings suggested continuing the quail breeding research for producing a suitable meat-type quail genotype in our country. \u0000SAARC J.

Biochar as a soil amendment has been found effective in increasing crop production. Here, we reviewed various biochar studies carried out in Nepal by different organizations and assessed future potential of biochar as an effective soil amendment. In this review, we have included the biochar pretreated (enriched) with nutrient or added separately in soil. We found that good quality biochar could be produced using the novel flame curtain metal and soil pit “Kontik” kiln with slow pyrolysis technology. Biochar produced from Kontiki found having high pH (9.8), organic carbon (OC, 72%), surface area (215 m2g-1) and cation exchange capacity (CEC, 72 cmol kg-1). Further, biochar application improved soil chemical properties (pH, OC, CEC, base cations) and nutrient availability such as available phosphorous (P) and potassium (K). Similarly, biochar addition increased crop yield significantly compared with non-biochar plots. Higher crop yield was achieved when biochar was enriched or charged with cattle urine. Thus, from this study, we suggest that biochar should be prioritized in government programs as a potential soil amendment and scale up or increase its use at farm level. \u0000SAARC J.

Two native duck varieties, Rupali and Nageswari of 6th generation were selected aiming to increase their laying performances. A total of 540 ducklings of both genotypes were hatched and brooded in brooder house. Male and female ducks were separated and marked with wing band at 12 weeks of age. At 40 weeks of age, a total of 300 ducks of both genotype were selected on the basis of selection index comprising the parameters of age at first egg, body weight at first egg, egg production % and egg weight. The individual with the higher total score was selected for breeding purposes. Selected male and female ratio were 1:5 using natural mating. The selection intensity and expected selection responses of selection criteria of two duck genotypes were estimated. Selection responses for ASM (day), egg weight (g) and egg production rate was -1.84, 1.08 g and 0.45 in case of Rupali and -1.66, 1.35 and 0.73 for Nageswari, respectively. Egg production % was numerically higher in Rupali (60.12%) than Nageswari (58.41%). Egg weight (EW) and feed intake were significantly differences between two native ducks where both higher values were found in Rupali (EW 64.83g and feed intake 134g) than Nageswary. Egg shape index was significantly higher in Rupali (76%) than Nageswari (75%) duck. In conclusion, Rupali ducks showed better production performance and it is suggested that selective breeding of duck may have significant impact on the development of native duck.\u0000SAARC J.

Therefore, this research was carried out at Fruit Crop and Development Center, Horana, Sri Lanka to screen the effects of leaves of four different crops and another 13 underutilized wild plant species on their suitability in the mass production of Trichoderma harzianum L. Seventeen different media were prepared using green leaves (5g) of individual plant species comprised with glucose (5g/L) and distilled water (50ml). Treatments were arranged in Complete Randomized Design (CRD) with five replications. Spore counts of fungus were recorded using hemocytometer at 1st, 2nd, 3rd and 4th week after inoculation. Different treatments showed significant variations in spore counting of T. harzianum after 1st, 2nd, 3rd and 4th week of inoculation (p<0.05). Castor (9.8x107 CFU/ml), gadapana (9.64x107 CFU/ml) and erabadu (9.64x107 CFU/ml) had significantly higher spore count at the 1st week while kappettiya (25.31x107 CFU/ml) and habarala (25.21x107 CFU/ml) had the highest values at 2nd week. Significantly increased spore count of 61.5x107 CFU/ml and 61.2x107 CFU/ml were resulted from castor and kappettiya during 3rd week after inoculation. However, a sharp increase in spore count was found at 4th week, particularly in wal sooriya kantha (157.17x107 CFU/ml) while in contrary, the lemon, rambutan, bovitiya, jack and mango leaves showed poor performances in the mass production of T. harzianum. Based on these results, wal sooriya kantha can be successfully used as growing media for T. harzianum.\u0000SAARC J.

P. hysterophorus examined the prospects of using allelopathic extracts during the period of July 2021 to June 2022. Experiments were conducted in the net house at Sher-e-Bangla Agricultural University, in non-cropped areas of Khustia and cropped areas of Chudanga. The net house experiments were laid out in complete randomized design (CRD) and replicated three times separately for each growth stage. Results showed that by using pretilachlor, pendimethalin, bensulfuron methyl + pretilachlor, bensulfuron methyl + acetachlor, oxadiazon, and pyrazosulfuron-ethyl + pretilachlor decreased the seed germination of parthenium at pot bioassay under both puddle and dry sown condition. At rosette stage of parthenium weed, glyphosate and carfentrazone ethyl (5%) + glyphosate with ½, ¾, and full doses gave 100% mortality at three weeks after treatment (WAT). In cropped areas carfentrazone Ethyl (5%) + glyphosate (36%) and quizalofop-p-ethyl resulted in a 100% and 90% mortality rate at 21 DAT. Overall, the efficacy of herbicides was more effective on rosette parthenium than bolted plants. A phytotoxic response to weed growth was induced by aqueous extracts of Oryza sativa L. var. Boteswar, Triticum aestivum L. var. BARI gom-21, Helianthus annus L., Datura metel, Mangifera indica L., Delonix regia, and Acacia nilotica. Delonix regia was the most effective for inhibition of germination (29%). Whereas Datura metel extracts and Oryza sativa var.

The experiment comprised of 3 levels of spacing; S1- 20 cm × 10 cm, S2- 30 cm × 10 cm and S3- 45 cm × 15 cm; and 6 levels of fertilizers; F0- Control (without fertilizer), F1- Recommended dose of NPK, F2- 5 t ha-1 cowdung, F3- 5 t ha-1 cowdung + Recommended dose of NPK, F4- 2.5 t ha-1 cowdung + Recommended dose of NPK and F5- 2.5 t ha-1cowdung + ½ Recommended dose of NPK. Among different treatments maximum number of leaves (13.70), branches (2.44) and dry weight (10.97g) was recorded from S3 at 60 DAS on the other hand highest number of leaves (13.83) found in F4 and dry matter (8.89g) in F3 at 60 DAS. However, when combined with fertilizers and spacings, the S3F4 treatment had the highest dry matter weight (12.7g) before harvest. In terms of yield performance, applying cowdung @ 2.5 t ha-1 along with recommended NPK resulted in the highest seed yield (1156.7 kg ha-1). The number of plant populations was higher in S2 (30 cm 10 cm) than in S3 (45 cm × 15 cm), so S2 produced the highest grain yield (1022.8 kg ha-1).

Molecular characterization and genetic diversity of 10 local potato genotypes of Bangladesh were investigated with five RAPD primers, namely OPA-18, OPB-06, OPC-01, OPD-02 and OPW. Genomic DNA was extracted from young leaves and PCR reactions were performed with selected primers. The selected primers generated 33 distinct and differential amplified bands (size ranged from 131-1188 bp), out of which 28 were polymorphic. The percentage of polymorphic loci was valued from 33.33% to 100%. Gene frequency was ranged from 0.300 to 1 and gene diversity was from 0 to 0.70. The inter-varietal similarity indices was ranged from 42.45% to 92.67%. Pair-wise comparisons of Nei's genetic identity value was from 0.4848 to 0.9394. The highest Nei's genetic identity (0.9394) was observed in Sheel Bilati and SAU Promising Genotype-5 genotype pair. Nei's (1972) genetic distance was from 0.0625 to 0.7239.
