This study was conducted in the Northern Region of Ghana to assess the growth performance of two different Hevea brasiliensis clones namely IRCA 41 and GT 1 in the Guinea Savanna soil. The fresh rubber stumps which were used for the experiment were collected from Ghana Rubber Estate Limited (GREL) which is located in the Western Region. The research design employed the use of completely randomized design with thirty replicates each of the two Hevea brasiliensis species. Data was collected during the dry and rainy seasons. The results at the end of the project for the two Hevea brasiliensis clones showed an average germination rate of 86.66% and 73.30% during the rainy and dry seasons respectively. A mean height of 25.30cm, mean girth of 6.34mm and mean leaf number of 28 were recorded during the rainy season whiles a mean height of 22.56cm, mean girth of 3.41mm and mean leaf number of 42 were recorded in the dry season for the two Hevea brasiliensis clones. When T-test was performed on the two Hevea brasiliensis clones, it was revealed that, there was no significant difference (p>0.05) in height, girth and number of leaves between the two different rubber clones during the rainy season and the dry season. Hevea brasiliensis therefore has a greater potential for cultivation in Guinea Savanna soil.

This paper focuses on the impact of climate change on the lives of rural farmers in the Pwalugu and Balungu communities of the Upper East Region of Ghana since farmers all over the country have been exposed to various adaptation strategies to climate change. From the study which was conducted in 2017, it was revealed that climate change affected respondents negatively resulting in reduced income level, inability to afford three square meals daily, inability to meet their health needs, inability to meet the educational needs of their children as well as inability to save at bank. Also, lack of finance, land tenure, norms/customs, lack of storage facilities, lack of ready markets, damage to crops by Fulani cattle and difficulty in obtaining seeds for farming were some challenges militating against the adoption of other adaptive strategies to climate change. The farmers therefore practiced crop diversification, adjustment in planting date of their crops, irrigation, change method of pr oduction, migration to the southern part of the country during the dry season to work, trading, fishing, among others as their specific adaptive strategies to climate change. The study recommends that, education should be one of the areas for policy intervention by government/stakeholders since access to education is vital in developing specific strategies of rural farmers to the diverse drivers and impacts of climate change on their lives.

This research investigated the allelopathic effects, the yields and qualitative phytochemical screening of the water extract of root exudates of five weed species i.e. Cyperus rotundus L. (T1), Marselia quadrifolia L. (T2), Ludwigia hyssopifolia (G. Don) Exell, (T3) Pistia stratiotes L. (T4) and Colocasia esculenta L. (T5). The allelopathic tests of root exudates on five weed species showed that all the extracts had the pronounced inhibitory effect on cowpea and mungbean (tested crops). The yields of root exudates of the selected weed species varied. Root exudate of T3 showed the highest yield whereby T1 contained the lowest one. A preliminary phytochemical test showed the positive result of alkaloids, flavonoids, phenols and carbohydrates whereas proteins, amino acids, tannins, saponins, have been found to be absent in the root exudates of tested weeds. The results evidenced that these mentioned weeds contain compounds in their root exudates which may cause allelopathic effects on both tested crops.

In ecological terms, modern cities consume 75% of world resources with 2% of global land area and have become a parasite and a resource sink. Unmanaged planning and rapid development often result in the destruction of natural resources and loss of greenery. Pokhara is rapidly urbanizing into a megacity in Nepal and climate change caused by global warming is a great menace here. To support the rising requirement of quality food for the skyrocketing population, the main consumption centre should be mobilized for food production. Rooftop gardens are gaining relevance as they have the potential to meet the growing demand for food in cities and enhance the ecosystem along with the conservation of biodiversity. Thus, the addition of greenery element such as a green roof is becoming a trend to solve this problem in Pokhara. Establishment of green roofs in Pokhara city is arousing the interest of the government and public due to their demonstrated environmental benefits. The objective of this research is to inspect the existing practice and obstacles in rooftop farming that is faced by pr actitioners. Nagdhungha and Birauta are the areas of research here. Two practitioners are interviewed and sixty nonpractitioners are surveyed. The result shows that rooftop farming can benefit the environment by greatly reducing carbon in the atmosphere and can assist urban areas by reducing stormwater management cost. Furthermore, the paper demonstrates that the willingness to practice rooftop farming is high among urban dwellers and for future scope, some recommendations are provided in this research.

A sixty days laboratory incubation study was conducted to investigate the effect of heavy metals on soil carbon, nitrogen and iron mineralization under aerobic condition. Sulphate salts of cadmium, zinc and copper were added individually and in combinations to soil samples and incubated in different plastic pots. Soil organic carbon did not change significantly throughout the incubation period. Soil microbial biomass carbon declined from 0.38mgkg-1to 0.19 mgkg-1 in Cd treated soil and 0.39 mgkg-1 to 0.28 mgkg-1 in Cu treated soil which account for about 50% and 28% reduction (p ≤0.05) in biomass carbon respectively. Cd:Zn and Cu:Cd treated soil had reduced 36.84% while Zn:Cu had 42.11% reduction in biomass carbon.CO2-C effluxes peaked by day 15 for all the single metal amended soil indicating that priming effects might have occurred. But in combination, metal showed some interaction for what the respiration rates were declined for the first 15 days. Rapid ammonification with presumed immobilization to ok place up to day 30. The result indicated a significant (p ≤0.05) net mineralization of nitrogen for Cd:Zn (63.72%) and Cu:Cd (66.66%) treatments at the end of the experiment. Available iron content showed significant changes in combined metal treatment than a single metal.

The study was conducted to evaluate the effect of photoperiod on the growth performance and behavioral pattern of Achatina achatina. Ninety snails of uniform weights were used for the study which lasted for 56 days. The snails were randomly assigned to three treatments and each treatment was replicated three times with 10 snails per replicate. The snails were exposed to different light duration. Treatment 1 had 12 hours light and 12 hours darkness, Treatment 2 was subjected to 18 hours light and 6 hours darkness, Treatment 3 was subjected to 24 hours light. The data collected was analysed using one-way analysis of variance and Duncan multiple range test for significant mean separation. Data were collected on feed intake, weight gain, time of feeding and reproductive behaviors. The results of the experiment showed that there were no significant differences (P>0.05) in final weight gain, average daily weight gain, total feed intake, average daily feed intake, feed conversion ratio, duration of courtship, duration of feeding and cost of feed per kg weight gain between tre atments. The results also showed that there were significant differences in number of eggs laid and mating duration between treatments. From the result, it was concluded that the best photoperiod for Achatina achatina is 24 hours light as it produced the lowest feed conversion ratio and cost of feed per kg weight gain and that was recommended for effective growth of Achatina achatina.

The rapid increment of low and middle-income consumers is exerting pressure on the food supply in urban areas. The objective of the study was to identify the present status of rooftop gardening. The study was conducted in the 4 selected residential areas of Dhaka city through plot to plot interview by using questionnaire. Land use nature is divided into four categories like residential, commercial, educational and mixed. Field survey was conducted on 1376 buildings in Dhanmondi, 391 buildings in Lalmatia, 272 buildings in Mohakhali Defense Officers Housing Society (DOHS) and 697 buildings in Uttara 13 no. Sector. Study found that, 39.1%, 59.2%, 36.6 % and 22.2% buildings have rooftop gardening in those selected locations respectively. The study reveals that, nearly one-third of the buildings (36.4%) contain rooftop gardening which basically depends on the aesthetic sense and moral values of individuals. Government should appreciate initiatives and consider proper planning policy to motivate citizen of the urban areas for planting fruit plants and vegetable in their roof. RTG system may also contribute to achieving the Sustainable Development Goals (SDGs). The proposed study identifies the need for long-term policy measures for rooftop gardening that can become the basis for a sustainable approach for urban agriculture.

In Bangladesh average sesame production is lower than other sesame producing country of the world, Therefore an experiment was conducted using five sesame M5 mutants along with the mother variety to observe their performances regarding seed yield and other yield attributes. Analysis of variance showed highly significant variations among the mutants and check for most of the characters. The mutant SM-07 required the shortest maturity period and produced the tallest plant and highest number of capsules plant-1 in each location and combined over locations, where as SM-01 and the mother variety Binatil-1 required the longest maturity period. Results over different locations also showed that the three mutants SM-06, SM-04 and SM-07 produced significantly higher seed yield (1477, 1449 and 1438 kg ha-1, respectively) which was 7.3, 5.2 and 4.4% higher than the mother variety Binatil-1 with seed yield of 1377 kg ha-1. This suggests that mutation techniques can be fruitfully applied to develop variety with higher seed yield and other improved agronomic traits of sesame.

A field experiment was conducted to find out the spacing of potato – brinjal intercropping system and land utilization and economic return at the Regional Agricultural Research Station, Jamalpur during rabi 2017-2018. The experiment was laid out in randomized complete block design (RCBD) with three (3) replications and six treatments. Cultivation of potato with brinjal at potato (60 cm × 25 cm) + brinjal (120 cm × 75 cm), Potato (50 cm × 20 cm) + Brinjal (100 cm × 70 cm), Potato (50 cm × 20 cm) + Brinjal (100 cm × 75 cm) might be agronomically feasible and economically profitable for potato and brinjal intercropping system as compared to sole treatment. Potato (50 cm × 20 cm) + Brinjal (100 cm × 70 cm) best performed in gross return, gross margin and potato equivalent yield (PEY 49.14 tha-1) compared with the other treatments. The total yield of intercropped crops was greater than sole cropping, shown by LER>1. The overall advantage of intercropping ranged from 73 to 92%. The hi ghest land equivalent value of 92% was recorded for Potato (50 cm × 20 cm) + Brinjal (100 cm × 70 cm) arrangements indicated a yield advantage of 92% over sole crop. Viable agronomic option in increasing land use efficiency and increased food security. It is, therefore, imperative to demonstrate the best treatment under farmer’s condition.
