The dataset includes seven inbred lines as female parents (L) and two testers as male parents (T) with diverse genetic bases and heat tolerance qualities. Fourteen cross combinations were produced through L × T (7 × 2) mating design, involving hybridization between lines (f) and testers (m) in a one-to-one fashion. To assess the heterosis of the crosses, all parents (both lines and testers) were included along with the crosses and evaluated in the same experimental field for 16 traits using a randomized complete block design (RCBD) with two replications. The line × tester analysis estimates the ANOVA, including parents, combining ability, genetic components, and the contribution of parental lines to genetic variation in the hybrids. This dataset is valuable for breeders in subtropical countries to develop efficient breeding strategies for hybrid summer tomato varieties.

The best response of shoot proliferation was obtained in embryo explants grown in supplemented with 10.8 mg/l BA, 1.08 mg/l NAA and 0.54 mg/l GA3; whereas, shoot regeneration on cotyledon was achieved on a MS supplemented with 16.2 mg/l BA, 2.7 mg/l NAA and 0.54 mg/l GA3. In both cases shoot primordia emerged continuously. This system exhibited a potential for repeated harvesting of the shoots from the original explant as the latter continued to expand and regenerate new shoots, upon repeated periodical subculturing on to fresh medium. Regenerated shoots were excised from both sources and rooted in MS supplemented with different ...

A randomized complete block design was adopted for the experiment with three replications. Four variety viz. BAU-1, BINA Chola-4, BINA Chola-5 and BINA Chola-9 and two planting method i.e. line sowing and ridge sowing were used in the experiment. The highest seed yield (1.81 ton/ha) was obtained from BINA Chola-4 and the lowest one (1.31 ton/ha) was found in BARI Chola-9. The seed yield was higher in ridge sowing (1.57ton/ha) and the lower (1.53 ton/ha) in line sowing. The highest seed yield (1.83 ton/ha) was obtained from BINA Chola-4 with ridge sowing and the lowest (1.30 ton/ha) was obtained from BARI Chola-9 in line sowing. It is concluded that ridge sowing is better than line sowing for the yield of chickpea. J. bio-sci. 28: 105-110, 2020

This study describes a protocol for in vitro callus induction and plant regeneration from leaf and stem explants of C. argentea using Murashige and Skoog (MS) medium. Callus culture was initiated and established from seedling, leaf, and stem explants. Explants were cultured on MS medium supplemented with auxin alone (0.5 mg/L Naphthaleneacetic acid (NAA), 2, 4-Dicholorophenoxyacetic acid (2, 4-D). Green and red compact callus (98%) were induced using MS medium supplemented with 0.5 mg/L NAA and 1.0 mg/L Benzyladenine (BA). Two different concentrations (1.0 mg/L BA + 0.5 mg/L NAA and 1.0 mg/L BA + 1.0 mg/L NAA) successfully induced plant regeneration with multiple shoots (1.5 and 0.9 shoots per explants, respectively). Successful shoots were transferred to rooting medium supplemented with 1.0 mg/L Indole-3-acetic acid (IAA) (80%) at 35 th day. Acclimatization was done, which resulted in 90% of the plantlets surviving in garden soil. This protocol could be used to micropropagate C. argentea for conservation, commercial natural product production. The high frequency of callus indicated potential of C. argentea for secondary metabolite production (celosin) in pharmaceutical industry.

As a result, real benefits of the systems are untapped. An On-Farm experiment was conducted during April 2017 to April 2018 in jackfruit orchards by transforming into multistorey agroforestry system (MAFS) in terrace ecosystem of Bangladesh to evaluate the productivity, economic and ecological performances of the system. Three spices (turmeric, ginger and chili) and papaya were grown as lower-and middle-storey crops, respectively. Established jackfruit trees were kept as topstorey crop. Four distances from tree base (1 m, 2 m, 3 m, and 4 m) and open field (non-agroforestry) were considered for the performances of spice crops, while performances of papaya and jackfruit were compared between agroforestry and non-agroforestry systems. The findings of the study revealed that the yields of chili and papaya were reduced by 15.06% and 26.83%, respectively, in MAFS than non-agroforestry. In contrast, the yields of turmeric, ginger and jackfruit were increased by 8.19%, 14.72%, and 27.06%, respectively. Results also showed that understory crop yields were increased with increasing distances from tree base. Light availability on understory crops varied between 15 and 35% at different distances from tree base. Soil moisture and soil temperature showed reverse pattern in agroforestry and non-agroforestry systems. Despite, some adverse effects on yield parameters of under-storey crops, the net return, benefit cost ratio (BCR) and land equivalent ratio (LER) were remarkably higher in MAFS than non-agroforestry system.

A study plot was set up in each location where Integrated Crop Management (ICM) practices recommended by the Tuber Crops Research Centre (TCRC) of BARI was followed in half of the plot and in the other half, Farmers’ conventional Practices (FP) were followed. It was found in all locations that there were distinct differences between the ICM practice and the FP in respect of yield. In all locations except those of Bogra, farmers used fertilizers in higher doses than the recommended doses. Insecticides were not used even in the seed production plots in most of the study areas but fungicides were used in more than the recommended quantity resulting in misuse and environmental hazards. All farmers obtained lower yields in their practices ...

A young malta (Citrus sinensis) orchard (3 years old) was transformed into a fruit tree-based agroforestry system in which the performances of summer (okra and Indian spinach) and autumn (mungbean and kangkong) crops and year-round spices (ginger and turmeric) were evaluated following randomized complete block design (RCBD) with three replication each and eventually compared between agroforestry systems and respective sole cropping (control) from March 2018 to February 2019 at BSMRAU field. The experimental results revealed that the yields of the associated crops deprived when grown at the closest row position from the bed of malta tree and spices. Yields of okra, Indian spinach, mungbean, kangkong, turmeric and ginger were reduced by 7.57, 6.52, 14.86, 13.26, 9.70 and 16.23%, respectively under agroforestry system as compared to control. However, malta yield was increased by 5.35% in agroforestry system than control trees. The findings also indicated that the crops in agroforestry system was less hindered by the shade effect of malta trees due to less dense canopy of young malta trees. In comparison to sole cropping system, the higher benefit-cost ratio (BCR) (2.93) and land equivalent ratio (LER) (2.83) were obtained in the studied agroforestry system that explicated higher system productivity and land uses. Notable improvement of total nitrogen and organic matter were obtained in the soil under agroforestry system. Therefore, malta-based agroforestry system can be a promising alternative to provide higher economic benefits, boosting food and nutritional security, improving soil nutrient status and utilization of land.

However, most of the jackfruit orchards are often found utilized or underutilized. A field experiment was conducted under the jackfruit orchard to study the performance of aroids (Colocasia esculenta L.) from April to October, 2017 in Belabo upazila of Narsingdi district. Four distances (1, 2, 3 and 4 m) from the base of jackfruit tree were considered for aroid planting to evaluate its performance as agroforestry crop in comparison to sole aroid. Land use and economic performances of agroforestry and sole systems were also evaluated. The results indicated that the production of jackfruit increased by 62.73%, while the yield of aroid reduced by 33.48% in agroforestry systems as compared to the yields of sole (non-agroforestry) systems. In agroforestry system, the photosynthetically active radiation (PAR) was severely reduced by 85-77% on aroid crop that caused yield reduction. It was also observed that soil temperature was lower in agroforestry system as compared to sole cropping of aroid, while soil moisture showed inverse trend in sole jackfruit. Economic analysis in terms of benefit cost ratio (BCR) was 2.60 in agroforestry, while the BCR of sole aroid was only 1.83. The land equivalent ratio (LER) was 2.31 in agroforestry system. The present results indicate that aroid cultivation in jackfruit-based agroforestry system under terrace ecosystem can ensure overall higher production and improve economic return.

Eighty DAP harvest resulted the lowest mean total soluble sugar (TSS) (3.77 mg/g FW), reducing sugar (RS) (1.57 mg/g FW), sucrose (2.40 mg g-1 FW), fructose (0.77 mg/g FW) and polyphenol (238.94 µg/g FW) contents in all the varieties and at the same DAP harvest, dry matter (DM) content (21.71%) and chip color index (CCI) (0.67) remained at the lowest. Tubers harvested at 80 DAP produced good quality and acceptable colored processed products as it meets up the required processing quality, but lesser DM content might increase the cost of the product. Optimum DM content (24.07%) with moderate level of different sugar contents and acceptable CCI (1.13 to 1.85, <2.00) was found at 90 DAP harvest. Therefore, 90 DAP harvest could be considered as suitable harvesting date for processing by compromising some quality parameters (TSS, RS, sucrose, fructose and polyphenol contents). Among the varieties, Lady Rosetta and Courage were preferable for producing quality potato products. Highly significant and positive correlation existed between CCI and different chemical parameters. A strong correlation coefficient (r = 0.822 **) and good fit (R 2 = 0.6755) of the regression equation (CCI = 0.9341RS-0.4969) between CCI and RS indicated that RS content played the vital role in the browning of the processed potato products.

Final harvest of tuber was done at 90 DAP. LAI, CGR, RGR and NAR were not significantly influenced by the varieties. Irrespective of varieties, LAI increased progressively with time reaching a peak at 60 DAP and thereafter declined. Granola maintained the lower LAI throughout all growth stages. Numerically, the maximum CGR (19.99 g m-2 day-1) was found in Asterix at 50-60 DAP and the highest RGR (107.33 mg g-1 day-1) as well as NAR (9.54 g m-2 day-1) was recorded in Cardinal at 30-40 DAP. At 60-70 DAP, Cardinal recorded the highest TBR (84.35 g m-2 day-1) while Asterix, the highest TGR (18.54 g m-2 day-1) but Granola gave the lowest values of TBR (65.21 g m-2 day-1) and TGR (14.92 g m-2 day-1) at this growth stage. At all growth stages except 30 and 40 DAP, Diamant showed the best performance in SLA while Granola showed the lowest. The maximum yield was produced by Asterix (31.46 t/ha) closely followed by Diamant (29.91 t/ha) and Cardinal (27.27 t/ha) while the lowest yield was produced by Granola (24.82 t/ha). Granola showed the capacity of producing 95% or more of its final yield within 60 to 70 DAP. Therefore, Granola can be used as an early variety for potato cultivation.
