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...

Production of high quality seeds in African leafy vegetables has not been practiced due to varying reasons including incorrect harvesting stages and fertilizer rates. Jute mallow (Corchorus olitorius L.) pods do not ripen simultaneously and fruits left to dry on mother plant long before harvesting, which face seed quality deterioration. Timely seed harvesting ensures maximum seed quality attrib...

There is little information about the effects of ethephon ripening hormone on the yield of sweet sorghum in Thailand. Therefore, this study aimed to evaluate the impact of ethephon hormone applied at different growth stages of three cultivars of sweet sorghum on its growth and yield. The experiment was conducted from December 2016 to May 2017 at a research plot of the Faculty of Agricultural Te...

rice is one of the most important staple cereals‏ ‏in iran and has a main role in providing ‎the food ‎security. harvesting by hand postpone the rice harvesting stage, and facing late season ‎rainfall, and increase of yield losses during harvesting. to determine the most suitable ‎harvesting method in gilan, three different harvesting methods (by hand, harvester and ‎combine) were considered as...

wheat stubble (ws) and date palm leaf (dpl) were inoculated with pleurotus florida where in a completely randomized experiment, seven treatments including: 1)untreated ws (utws); 2) fungal treated ws at mycelial running stage (mtws); 3) fungal treated ws after first harvesting of mushroom (ftws1); 4) fungal treated ws after second harvesting of mushroom (ftws2); 5) untreated dpl (udpl); 6) fung...

Sustainable yields that are at least 80% of the maximum sustainable yield are sometimes referred to as pretty good yield (PGY). The range of PGY harvesting strategies is generally broad and thus leaves room to account for additional objectives besides high yield. Here, we analyze stage-dependent harvesting strategies that realize PGY with conservation as a second objective. We show that (1) PGY...

The method to obtain electrical equivalent models of piezoelectric materials used in energy harvesting road traffic environment is presented in this paper. The experimental results are processed in order to determine the optimal topological structure and technology of the semiconductor elements used in the input stage of the power harvesting system. The non regulated power supply model under va...
