Aim: To evaluate under agro-environmental conditions of Gimbi research station, some agronomic traits of four groundnut varieties from germplasm of PNL.
Study Design: This study was conducted using a randomized complete block design with four treatments repeated three times.
Place and Duration of the Study: The study was conducted in Gimbi research station between October 2019 and January 2020 (i.e. 4 months).
Methodology: Trial was conducted using four treatments with three replications. Data collected concerned percentage of seedlings emerged, number of days between sowing and flowering 50%, dry pod weight, weight of unsorted seed, weight of sorted seeds, percentage of good seeds, shelling percentage, average weight of 1,000 seeds and grain yield per hectare. All data were submitted to analysis of variance at 5% probability level.
Results: The rate of seedlings emerged recorded on each groundnut variety was overall less than 50%. All varieties flowered 32 days after sowing. The highest average weight of dry pods (410.8g) was noted on A1408, while the lowest value of dry pod weight (310.6g) was observed on JL24. The highest weight of unsorted seeds (360.9g) was recorded on A1408, while the lowest value (260.7g) was observed on JL24. Variety A1408 presented the highest weight of stored seeds (350.5g), while the lowest value (250.8g) was noted on variety JL24. The highest percentage of good seeds (97.3) was obtained on A1408, while variety Sivi presented the lowest percentage of good seeds (93.2). The highest shelling percentage of groundnut pods (87.6) was obtained on A1408, while the lowest shelling percentage (83.5) was noted on JL24. The lowest weight of 1,000 seeds was noted on Sivi variety (484.6g), and the highest value was recorded on A1408 (522.6g). The highest grain yield (912.9Kg.ha-1) was obtained on variety A1408, while the lowest grain yield was noted on JL24 (690Kg.ha-1).
Conclusion: Seeds of all varieties presented a very low rate of emergence (less than 50%). Variety A1408 was more productive than other varieties, and variety JL24 used as control should be regarded as having degenerated.

Aims: The field experiment was conducted to evaluate new sesame varieties for growth and yield performance.
Study Design: A randomized completely block design (RCBD) with four replications was used for the experiment.
Place and Duration of Study: The study was conducted during the Deyr season (September-November) 2016 at the experimental farm of Somali Agriculture Technical Group (SATG), Afgoye, Somalia.
Methodology: Growth and yield characters of the varieties were measured during the trial. A complete of six sesame varieties was used for the trial. The new varieties were Setit, Yemeni, Nigerian, Humera and Indian while a local variety, Dunyar, was used as a control.
Results: Results from the experiment revealed that growth parameters such capsule length, number of branches per ∙plant, number of capsules per plant and number of seeds per capsule were significantly different among the varieties. Yield performance of the sesame varieties was also significantly different. It was observed that Humera variety showed the highest seed yield of 2.82 ton per hectare while the Indian variety has given the lowest seed yield of 0.67 ton per hectare. The highest straw yield of 3.45 ton per hectare was recorded for Local variety while the lowest straw yield of 2.76 ton per hectare was observed in Setit variety. Likewise the highest biological yield of 6.18 ton per hectare was observed at Dunyar variety while the lowest biological yield of 3.61 ton per hectare was recorded for Indian variety.
Conclusion: The growth and yield of these particular varieties did not outperform the local variety, thus, future studies would be essential to look for other alternative methods and cultivars that would help increase the productivity.

The experiment was conducted in the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh with aim to find out the suitable variety, optimum nutrients and suitable combination variety and optimum nutrients for maximum growth, yield of French bean in Bangladesh. The experiment consisted of two factors. Factor A: different varieties as V1 = BARI French bean-1, V2= BARI French bean-2, V3= BARI French bean-3 and Factor B: different level of nutrients as N1= cowdung (5 t/ha) + vermicompost (2 t/ha), N2= cowdung (5 t/ha) + N90 P30 K45 kg/ha, N3= cowdung (5 t/ha) + vermicompost (2 t/ha) + N90 P30 K45 kg/ha. The experiment was laid out in a Randomized Complete Block Design with three replications. In case of different varieties of French bean the maximum number of flowers (27.83), the highest number of pod harvested per plant (22.14) and the highest pod yield (15.95 t/ha) were found from V2, whereas the lowest was from V3. For the different levels of nutrients1 the highest number of flowers (25.58), the highest number of pod per plant (20.60) and the highest pod yield (14.10 t/ha) were recorded from N2 treatment, while the lowest was from N1 treatment. Due to the combined effect, the maximum number of flowers (32.02), the maximum number of pod harvested per plant (26.50), the highest pod yield (18.92 t/ha) were observed from V2N2 treatment combination, while the lowest were from V3N1 treatment combination. Therefore, the V2N2 treatment combination appeared to be the best for achieving the higher growth and yield of French bean.

Aims: The research aimed to study the potential of cow dung fertilizer residue in increasing the growth and yield of corn plant in planting period II on marginal dry land.
Study Design: Singel factor design in Randomized block design.
Place and Duration of Study: The research was conducted in Field Laboratory of the Faculty of Animal Husbandry, University of Halu Oleo, Kendari, Southeast Sulawesi, Indonesia. The study was conducted for four months.
Methodology: Single factor design in Randomized block design was used in the research. consists of 6 treatment levels of cow manure residue that have been applied in the previous planting period (planting period I), namely: without cow manure (R0), using cow manure 2.5 t ha-1 (R1), 5 t ha-1 (R2), 7.5 t ha-1 (R3), 10 t ha-1 (R4) and 12.5 t ha-1 (R5). Each treatment was placed in three groups so that there were 18 experimental units. The data was analyzed using analysis of variance and continued by Duncan’s Multiple Range Test (DMRT) 95% confidence level.
Results: The results showed that the vegetative growth of corn plant 30 day after planting (dap) and plant yield was affected by residual effect of cow dung that applicated in the planting periode I, thus with P uptake by plant and available P in planting medium.
Conclusion: Plant productivity during planting period II more increased with the higher dose of cow manure applied during planting period I. The highest plant productivity (3.88 t ha-1) in planting period II was obtained by application of cow dung 12.5 t ha-1 during planting period I. While in the planting medium without cow dung, no seeds formation was found in plants.

Soil salinity is a pending threat to global agricultural sustainability and food security. The natural means of alleviating this stress have become the major concern as to which methods, mechanisms, and organisms to be used. Soil-borne fungi Trichoderma has proven to alleviate salinity stress in plants. This review aimed to shed light on the roles and mechanisms of some species of Trichoderma in response to salt stress and other merits to plant growth and development. Detailed of this research reviewed the level of growth promotion induced by Trichoderma species with an estimated increase of 200% of total plant biomass compared with control plants from literature. The defined mechanisms of Trichoderma in combating salinity stress in plants are; formation of ion channels in host plants, activation of ion exchange (K+/N+), increase Reactive Oxygen Species (ROS) scavenging enzymes, antioxidants, and genes, production of phytohormones and their signal pathways, stimulates root formation and developments, regulate stomata conductance through the increment of carotenoids in host plants which corresponds to the functions of the photosystems.
