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.

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.

Durio zibethinus, more commonly known as Durian or the ‘king of fruits’ by locals is a Southeast Asian tropical fruit. Smell is a crucial factor in durian acceptance amongst consumers as many are unable to accept the pungent onion-like odour liberated by durians. Due to the controversial aroma of durians, chemical compounds reportedly contributing to the durian smell- volatile esters and sulfur compounds have been widely discussed in the literature. This review article seeks to consolidate the literature which have identified volatile esters and sulfur-containing compounds in durians from Malaysia, Indonesia and Thailand, and studies shedding light on how the economic value of durians can be enhanced. Literature review was conducted using databases Scopus and ScienceDirect and a total of 18 articles were reviewed. In light of the rising demand for durians, factors, namely aroma, flavour and colour, in which consumers consider in the purchase of durians are further looked at, to explore the potential of enhancing favourable traits of durians and increasing its economic value and sales in the global market. By knowing the chemical compounds involved or influencing each factor, further studies can be conducted to explore methods such as breeding of new durian cultivars and metabolic or gene modification for phenotypic manifestation of favourable traits attractive to consumers.

The effect of rooting hormones, substrate and bottom heat was studied on the rooting of the cuttings of Picea abies. The treatments included bottom heat at two levels, hormones at six levels and rooting substrate at three levels. The recorded traits included rooting percentage, the number of roots; root length and root dry weight. It was found that the applied hormones had no considerable effect on rooting and the recorded traits, so that the application of 2000 and 4000 mg/l IBA had no significant difference with no-hormone application on all three substrates with or without the use of bottom heat. Cuttings treated with NAA produced no roots in any of the studied three substrates. The highest number of roots was produced under the treatment of sand + perlite × 4000 mg/l IBA × no-bottom heat. The treatment of no-bottom heat × no-hormone × perlite produced the longest root. The highest root dry weight was devoted the treatments of no-bottom heat × no-hormone × sand and no-bottom heat × 2000 mg/l IBA× sand.
