Improving the quality of agricultural products depends largely on production process. In absence data farmers’ practices and average cashew nuts in Cote d’Ivoire, present study aimed to provide a detailed description nut Thus, survey was carried out zones Mankono, Dabakala Bondoukou among 386 producers selected at random interviewed using face-to-face technique. The results revealed that interc...

Abstract. Fridayanti N, Widajati E, Ilyas S, Budi SW, Palupi ER. 2023. Phenology of flowering and seed development jernang rattan (Daemonorops spp.). Biodiversitas 24: 349-358. Jernang has a high economic value due to its resin content in the exocarp, as raw material dyes, medicines, cosmetics. The is highest immature fruit skin (exocarp); therefore, fruits are harvested before germinable. As c...

An Ambrosetti-Prodi type exact multiplicity result is proved for a diffusive logistic equation with harvesting. We show that a modified diffusive logistic mapping has exactly either zero, or one, or two pre-images depending on the harvesting rate. It implies that the original diffusive logistic equation with harvesting has at most two positive steady state solutions.

Trying to detect the genes coding for light harvesting II polypeptides of the purple bacteria Ectothiorhodospira sp. a gene corresponding to a light harvesting I polypeptide was cloned. This paper discusses the probable reasons of this result. The sequence of this polypeptide underlines the strong similarity with light harvesting complexes from bacteria such as Rhodospirillum molischianum and C...

Self-aggregation of isolated plant light-harvesting complexes (LHCs) upon detergent extraction is associated with fluorescence quenching and is used as an in vitro model to study the photophysical processes of nonphotochemical quenching (NPQ). In the NPQ state, in vivo induced under excess solar light conditions, harmful excitation energy is safely dissipated as heat. To prevent self-aggregatio...

to study the effect of harvesting time on soybean seed germination and vigor a factorial experiment with three replications, including of five harvesting time and three soybean cultivars was carried out in the field and glasshouse. the effect of harvesting time on seed germination percentage (in the field, cold test and paper test), seed germination rate, shoot and root weights, 1000-seed weigh...

Nacrtak A comparison of the ergonomic performance of 13 harvesting machine models was assessed from an ergonomic viewpoint. The main objective of the study was to compare ergonomic performance to harvesting machine operators’ work and propose viable solutions to improve the work environment. The principal assessed ergonomic requirements were operators’ workspace, operators’ seats, visibility, w...

Water harvesting systems have improved productivity in various regions in sub-Saharan Africa. Similarly, they can help retain water in landscapes, build resilience against droughts and dry spells, and thereby contribute to sustainable agricultural intensification. However, there is no strong empirical evidence that shows the effects of intensification of water harvesting on upstream-downstream ...

carbohydrate flow between vegetative and reproductive parts of trees is one of the determining factors of yield and fruit quality. therefore, it varies during different times of growth season. the aim of this study was to investigate the carbohydrate content variation during growth season between leaf and fruit of nectarine. so, eight nectarine trees cv. red gold selected randomly in the orchar...

rain-water-harvesting is one of the means by which agricultural production can be increased to meet the growing food demands in all regions. the study indentified the factor affecting rain-water-harvesting technology adoption for irrigation and farmers practice in water harvesting against drought in lowland woreda, eastern hararghe, oromia region. both primary and secondary data were collected ...
