The present study was carried out at the Research Field of Sher-e-Bangla Agricultural University (SAU), Dhaka during Boro season, 2021-2022 to discover the best nitrogen source for enhancing Boro rice grain production. The experiment consisted of two factors: A) Three varieties: BRRI dhan29 (V1), BRRI dhan58 (V2), and Heera (V3). B) Four nitrogen sources: no nitrogen (T1), BRRI-recommended prilled urea (T2), recommended dose of mixed NPK (T3), and BARC-recommended USG (T4). The experiment was laid out in split plot design with three replications where main plot was for nitrogen source and subplot was for variety. USG treatment resulted in the highest grain production (8.6 t/ha) and the lowest percentage of spikelet sterility of any nitrogen source tested. Except for harvest index, all of the examined characteristics differed considerably between types. This is mostly due to BRRI dhan29 having the maximum number of full grains (98.8/panicale) and a significantly lower degree of spikelet sterility (7.3%). Among the interaction effects, the combination of the USG application with BRRI dhan29 showed the greatest performance in terms of delivering the maximum grain production (9.3 t/ha) by significantly reducing spikelet sterility.

Plant growth-promoting rhizobacteria (PGPR) are multipurpose entities in case of crop quality and yield improvement. This study evaluated the impact of PGPR inoculation in root zone nutrient release, rice yield, and grain nutrient (P, Fe, Mn, and Zn) content in two popular rice varieties of Bangladesh (viz., BRRI dhan49 and Binadhan7). It was a single factor (bacterial treatment) experiment where B0, B1, B2, and B3 treatments represented the inoculated control, indole acetic acid (IAA) producing bacteria consortium, phosphorus solubilizing bacteria (PSB) consortium, and combination of B1 and B2 treatments, respectively. Nutrients released in pore water was higher at 5 days after transplanting (DAT), compared to 25 DAT. Mostly B2 and B3 treatments performed significantly in the number of tillers/pots, straw yield, grain yield, grain P, Mn, Fe content, and all four nutrients uptake. The highest grain yield observed in B3 treatment is in both Binadhan7 (42.10±1.76 g/pot) and BRRI dhan49 (36.20±1.57 g/pot). PSB containing B2 treatment bio-fortified the largest amount of P in both rice varieties. On the other hand, the B3 treatment stored the highest amount of Mn (46.70±1.30 and 44.30±1.37 mg/kg) and Fe (45.30±2.90 and 25.70±2.37 mg/kg) in Binadhan7 and BRRI dhan49, respectively. The B3 treatment resulted in maximum nutrient content (P, Mn, and Fe) and uptake (P, Mn, Fe, and Zn) in both rice varieties. These bacterial isolates seemed promising for rice yield and quality improvement in an eco-friendly and sustainable way. Res. Agric. Livest. Fish. 10(1): 73-81

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from November 2021 to April 2022 to assess the effect of sulphur fertilization and weed management on yield performance of faba bean. The experiment consisted of three levels of sulphur viz. 0, 20 and 40 kg S ha-1 and four levels of weed management practices viz. control (weedy check), weed-free up to 30 days after sowing (DAS), weed-free up to 60 DAS, weed-free throughout the growth period. The experiment was laid out in a randomized complete block design with three replications. The highest number of branches plant-1 (11.63), pods plant-1 (70.68), seeds pod-1 (5.50), 1000-seed weight (267.9 g), seed yield (2.72 t ha-1), and stover yield (2.93 t ha-1) were recorded with 40 kg ha-1. In the case of weed management, the highest number of branches plant-1 (10.16), pods plant-1 (66.03), seeds pod-1 (6.0), 1000-seed weight (266.7 g), seed yield (2.43 t ha-1), stover yield (2.85 t ha-1) and harvest index (45.80%) was found at weed free throughout the growth period. Whereas the lowest values of all parameters were found minimum in weedy check. In interaction, the highest number of branches plant-1 (13.0), pods plant-1 (78.69), seeds pod-1 (7.0), 1000-seed weight (269.5 g), seed yield (2.87 t ha-1), stover yield (2.98 t ha-1) and harvest index (49.37%) were found in 40 kg ha-1 S with weed-free throughout the growth period. Whereas the lowest parameters were found minimum in control. Therefore, application 40 kg ha-1 S along with weed-free conditions throughout the growth period appears as the suitable combination for faba bean cultivation. Res. Agric. Livest. Fish. 10(1): 33-42.
该试验于2021年11月至2022年4月在孟加拉国农业大学Mymensingh农学田间实验室进行，旨在评估硫肥和杂草管理对蚕豆产量性能的影响。试验包括3个水平的硫(0、20和40 kg S ha-1)和4个水平的杂草管理措施，即控制(杂草检查)、播后30天内无杂草、播后60天内无杂草、整个生育期无杂草。试验采用完全随机区组设计，设3个重复。40 kg ha-1时，单株分枝数最高(11.63)，荚果数最高(70.68)，籽粒数最高(5.50)，千粒重最高(267.9 g)，籽粒产量最高(2.72 t ha-1)，秸秆产量最高(2.93 t ha-1)。在杂草管理情况下，全生育期无杂草处理的单株分枝数(10.16)、荚果数(66.03)、籽粒数(6.0)、千粒重(266.7 g)、籽粒产量(2.43 t ha-1)、秸秆产量(2.85 t ha-1)和收获指数(45.80%)最高。而在杂草检查中，所有参数的最低值都是最小的。在互作过程中，40 kg ha-1 S全生育期无杂草处理下，单株分枝数(13.0)、荚果数(78.69)、籽粒数(7.0)、千粒重(269.5 g)、籽粒产量(2.87 t ha-1)、秸秆产量(2.98 t ha-1)和收获指数(49.37%)最高。而最低的参数在控制中被发现是最小的。因此，在整个生育期施用40 kg hm -1 S并在无杂草条件下施用是蚕豆栽培的适宜组合。阿格利司。力所能及的。鱼类。10(1):33-42。

Maize plays an important role both as food and feed throughout the world. For morphological characterization and evaluation of yield attributes of maize genotypes an experiment was carried out at the experimental field of the Department of Crop Botany and Tea Production Technology, Sylhet Agricultural University (SAU). The experimental materials were seven exotic maize genotypes viz.ZM 0001, ZM 0002, ZM 0003, ZM 0004, ZM 0005, ZM 0006ZM 0007 along with BARI Maize 6 as control. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Significant variations were observed among eight maize genotypes for most of the plant characters studied. The tallest plant was found in ZM 0005(246.5 cm). The highest number of leaves was produced in ZM 0001 (14.01). The longest and widest leaf was recorded in ZM 0004 (94.67 cm) and BARI Maize 6 (10.32 cm), respectively. The longest internode was found in ZM 0004 and ZM 0005 (21.61 cm). The genotype ZM 0004 was the earliest in respect of tasseling and silking. Ear height was highest in ZM 0005 (143.8 cm). The genotype ZM 0004 matured the earliest (109.3 days) while BARI Maize 6 matured the last (126 days). No variation was found for ear shape but in terms of kernel color, kernel type, kernel row arrangement and shape of upper surface of the kernel there were great variations among the genotypes. BARI Maize 6 produced the largest kernel with the highest thousand kernel weight. Grain yield plant-1 t ha-1 was highest in BARI Maize 6 which was closely followed by ZM 0005 and ZM 0004 among the studied genotypes. A correlation study between the yield and yield contributing characters showed that ear length, ear diameter, number of kernels row-1, kernel length, kernel width, kernel thickness, thousand kernel weights, and the weight of kernels ear-1, prolificacy index and weight of kernels plant-1 had a significant positive correlation with grain yield.

Soil salinity is a significant threat to agriculture and livelihood, particularly in the Southern coastal areas of Bangladesh. Soil salinity is extended from 0.833 to 1.056 million hectares (about), with an increase of 26% between 1973 and 2009. Out of about 1.689 million hectares of coastal land, about 1.056 million hectares are affected by soil salinity of various degrees covering 49 Upazila (sub-district) of 19 districts. About 0.328, 0.274, 0.189, 0.161, and 0.101 million hectares of land are affected by very slight (S1), slight (S2), moderate (S3), strong (S4), and very strong salinity (S5), respectively. Data recorded by SRDI manifests new ingression of salinity in Narail (18.71 ha), Jashore (14.99 ha), Barishal (13.96 ha), Gopalgonj (6.27 ha), Jhalakati (4.69 ha), and Madaripur (0.72 ha) districts. Soil salinity also encroached a large area of Bhola (53.84 ha), Patuakhali (40.08 ha), Khulna (27.92 ha), and Bagerhat (23.14 ha), besides minor ingression in other districts. The salinity level is almost double (2.8-18.5 to 4.0-42.8 dS/m) from 1973 to 2009 in Sharankhola Upazila of Bagerhat district, Dumuria Upazila of Khulna district and Shyamnagar Upazila of Satkhira district (SRDI, 2010). Different causes are involved in increasing the water and soil salinity of the coastal area of Bangladesh, like withdrawal of fresh river water from upstream, irregular rainfall, faulty management of sluice gates and polders, regular tidal water flooding in an unprotected area, the capillary rise of soluble salts, decreased surface water availability, lowered ground water table, reduced soil moisture content, the introduction of unplanned shrimp cultivation, lack of drainage facilities. Some of the widespread soil and land management techniques adopted in the saline areas of Bangladesh to cope with the salinity are polder (123), farm-pond (khamar-pokor), sarjan procedure, usage of raised shrimp farm bund for year-round cropping, mulching (keeping land covered in winter and summer months), land leveling, pitcher (kolosh) irrigation to grow watermelon, dibbling method, the addition of organic matter, chemical fertilizers and cultivation of saline tolerant crop varieties, particularly rice.

Demand for culinary herbs in many developing countries is currently growing due to the increased perception of their nutritional and medicinal properties. There is a need to understand consumers’ preferences for these products. This study, therefore, analyzed the determinants of consumers’ preferences for locally produced and imported herbs in Gauteng province. The data were collected with a stratified sampling method from 385 respondents using a structured questionnaire. Multinomial logit regression was then employed for data analysis. The results indicated socio-economic factors and product attributes such as labeling, the attractiveness of packaging, and availability as determinants of preference for both local and imported herbs. Based on these findings, the study recommends that the promotion of herbs must be inclusive of both product attributes and socioeconomic factors. Res. Agric. Livest. Fish. 10(1): 61-71

Sweet potato is an important food crop in Eastern Ethiopia, including the West Hararghe Zone. However, the area is still far behind in attaining the required optimum productivity of Sweet potato, this is due to biotic and abiotic factors, inappropriate Agronomic practices and lack of improved variety, to tackle these problems; variety improvement research is the major one. Therefore, the objectives of the study were to estimate the magnitudes of genotype, environment, and genotype by environment interaction effects on Sweet potato genotypes and to identify the high yielder and stable genotypes for wide adaptability in West Hararghe Zone, Eastern Ethiopia. The experiment was carried out at two locations (Mechara on station and Habro district) in three consecutive years (2018–2020) on 20 Sweet potato genotypes using a randomized complete block design (RCBD) with three replications. Additive main effects and multiplicative interactions analysis (AMMI) indicated that the yield performances of genotypes were under the major environmental effects of genotype by environmental interactions. The first two principal component axes (PCA 1 and 2) were significant (p≤0.01) and cumulatively contributed to 73% of the total genotype by environment interaction. In GGE bi-plot analysis using genotypic and environmental scores of the first PCA 1 and lower PCA 2 scores gave high yields (stable genotypes), and genotypes with lower PCA 1 and larger PCA 2 scores had low yields (unstable genotypes), as in the sites tested. Besides, genotypes G3 and G5 were stable across tested locations and gave higher total root yields (43.94t ha-1 and 49.34 t ha-1), respectively). However, G5 was recommended for possible release for wide adaptability in West Hararghe Zone and similar agro-ecology in the country. Res. Agric. Livest. Fish. 10(1): 43-52
甘薯是埃塞俄比亚东部包括西哈拉尔河地区的重要粮食作物。然而，该地区在实现红薯所需的最佳生产力方面仍然远远落后，这是由于生物和非生物因素，不适当的农艺做法和缺乏改良品种来解决这些问题;品种改良研究是其中的主要内容。因此，本研究的目的是通过环境互作效应估计基因型、环境和基因型对甘薯基因型的影响程度，并确定在埃塞俄比亚东部西哈拉尔河地区具有广泛适应性的高产和稳定的基因型。采用随机完全区设计(RCBD)，连续3年(2018-2020年)在两个地点(Mechara站和Habro区)对20个甘薯基因型进行试验。加性主效应和乘法互作分析(AMMI)表明，基因型的产量表现受环境互作的主要环境效应影响。前两个主成分轴(PCA 1和PCA 2)极显著(p≤0.01)，环境互作累计贡献了总基因型的73%。在GGE双图分析中，使用第一个PCA 1的基因型和环境得分和较低的PCA 2得分获得高产量(稳定基因型)，而较低的PCA 1和较高的PCA 2得分的基因型具有低产量(不稳定基因型)。此外，G3和G5基因型在不同的试验地点表现稳定，根系产量最高(分别为43.94t ha-1和49.34 t ha-1)。然而，由于在西哈拉尔河地区和该国类似的农业生态中具有广泛的适应性，建议可能释放G5。阿格利司。力所能及的。鱼类。10(1):43-52

This research focuses on the gender differences in agriculture in the village of Baje Mazkur in Kaunia Upazila. It demonstrates gender disparities in agriculture and elucidates the factors which prevent female farmers from receiving adequate recognition in a variety of ways in the study region. The study used a qualitative method to collect data and data has been analyzed from gender perspectives. To understand the work nature of female farmers, their struggles, and the reason for unrecognition the Agrarian Ideology and The Longwe Framework have been used. It shows that female farmers in the study area engage themselves in a variety of farming activities but their contribution to agriculture is viewed solely as family responsibilities where women are not recognized for their contribution. Female farmers are often unable to utilize their full potential because they are denied various extension services or support from government and non-government organizations. The findings also show that a lack of access to land, finance, and other resources are the most significant barriers to female farmers. Though the situation is gradually improving, women farmers continue to be paid less than men. Vol. 10, No. 1, April 2023: 09-19

The experiment was carried out at Agricultural Research Field, Noakhali Science and Technology University, Noakhali, Bangladesh during the period from November 2021 to March 2022, to observe the effect of nitrogen (N), phosphorus (P) and potassium (k) fertilizer on growth and yield of garlic (Allium sativum L. V: BINA Roshun-1). The experiment was laid out in a Randomized Complete Block Design (RCBD) comprising four treatments with three replications. The treatments were T0 (no NPK), T1 (NPK 70-70-100 kg ha-1), T2 (NPK 100-100-140 kg ha-1), T3 (NPK 130-130-180 kg ha-1), and here, N = Nitrogen, P=P2O5, K= K2O respectively. Data were recorded from harvesting stages of plant growth on the plant height, number of leaves per plant, leaf length, number of roots per plant, bulb diameter, bulb length, number of cloves per plant, whole weight of plant, fresh weight of bulb and fresh bulb yield per hectare. All the recorded parameters were statistically significant (p<0.01). The highest plant height (69.57 cm) was recorded from T3 (NPK 130-130-180 kg ha-1) whereas the lowest plant height (51.40 cm) was obtained from the control T0 (no NPK). The maximum number of leaves per plant (9.97), leaf length (38.10 cm), number of roots per plant (90.83), bulb length (3.30 cm), bulb diameter (3.80 cm), number of cloves per plant (28.97), whole weight of plant (65.07 g), fresh weight of bulb (42.50 g) and fresh bulb yield per hectare (2.83 t/ha) was found in treatment T3 (NPK 130-130-180 kg ha-1) whereas lowest data recorded from control T0 (no NPK). Observing the results, it can be stated that application of NPK fertilizer @ N 130 kg ha-1, P2O5 130 kg ha-1 and K2O 180 kg ha-1 for garlic cultivation gave better growth and yield in the coastal zone of Bangladesh.

This study was conducted to investigate the present status of dairy farming through a field survey at Rangpur Sadar Upazila, Rangpur, Bangladesh from December 2020 to December 2021. A total of 14 indigenous and 95 crossbred cows were selected randomly from the selected dairy herds. The results indicated that most of the farmers were male (25-35 years) and 17.24% of farmers involved in dairy farming were graduated. With regards to the housing system, the percentage of rearing system was found equal and the majority of the farmers could not afford fodder cultivation (70%). In the case of cross-breed animals like HF cross the farmers provided green grass and concentrate in a high amount of 11.03±0.76 kg and 4.82±0.33 kg per animal per day respectively. Likewise, straw feeding was found higher in indigenous animals (06.64±0.55 kg/animal/day). Most of the farmers followed AI (91.7%) with frozen semen (99.08%) for reproduction purposes in which 37.61% of cows need double services for conception. The age of first puberty was lower (19.97±0.57 months) in HF cows. In contrast, the average number of services per conception was lower in indigenous cows which was 1.95±0.14. The average milk yields of indigenous, HF, and SL crossbred cows were 2.36±0.118, 15.07±0.457and 3.2±0.287 L/day/cow, respectively. However, enhancing the availability of feeds and fodder, the proper market price of milk, and minimization of veterinary costs might improve dairy production in the study area as well as in other districts of Bangladesh.
