How do preharvest applications of nitrogen fertiliser affect branch growth, leaf morphology and fruit, in Mangifera indica (mango) orchards?

Objetivo: Caracterizar y evaluar las selecciones Ataulfo diamante’, ‘Zafiro’ y ‘Citlalli’ de mango (Mangifera indica L.), obtenidas en el programa de mejoramiento genético de mango en el Campo Experimental Rosario Izapa del INIFAP.Diseño/metodología/aproximación: Se realizó la caracterización morfológica de acuerdo a los descriptores propuestos por la UPOV. Se evaluó el comportamiento agronómico de los clones, y con los resultados de las variables se aplicó un análisis de varianza y una comparación de medias de acuerdo a Tukey con un a=0.05.Resultados: Se encontraron diferencias morfológicas entre los clones caracterizados y evaluados; las diferencias fueron en morfología del fruto, sabor y rendimiento.Limitaciones del estudio/implicaciones: El potencial productivo y la calidad de los clones de mango estará en función del manejo en campo y postcosecha que reciban los frutos.Hallazgos/conclusiones: Los clones ‘Citlalli’, ‘Ataulfo Diamante’ y ‘Ataulfo Elite’ presentan características productivas de alto potencial y registran calidad para ser considerados en programas de mejora de la productividad del cultivo en la región del Soconusco, Chiapas, México.

The Impact

The New Zealand dairy industry recognises that to remain competitive it must continue to invest in research and development. Outcomes from research have ensured year-round provision of low-cost feed from pasture while improving productivity. Some of these advances, discussed in this paper, include the use of white clover in pasture, understanding the impacts of grass endophyte, improved dairy cow nutrition, the use of alternative forage species and nitrogen fertiliser to improve productivity, demonstration of the impact of days-in-milk on profitability, and the use of feed budgeting and appropriate pasture management.

Cropping Seasons

Indian mustard (Brassica juncea L. Czern) cultivation is suggested for regions with short seasons and low rainfall. Although there have been many studies conducted on agronomic production of mustard in Iran, the information regarding the interactive impact of cropping seasons and nitrogen fertiliser on growth characteristics and yield quality of mustard plant is still insufficient and requires further investigation. This study focused on the possible implications of different cropping seasons and different nitrogen levels on selected agronomic traits in mustard. In this experiment, five different doses of nitrogen and two sowing periods were used to assess for their combined effects on the growth parameters, seed yield and agronomic characteristics of mustard in the semi-arid climatic conditions of Takestan. The results revealed that cultivation seasons and nitrogen rates had a significant effect on plant height, biomass yield, number of siliques per plant, seed oil content and seed yield.

Mango Leaves

Mites have hostplant specifications or host plants. Mites can be destructive and deadly of which is the host plants a mango crop. Mites on mango crops will cause the leaves yellow and fall off prematurely. This is will lead to the disruption of the productivity of mango. It is necessary for research to identify the mites that infect the mango crop. The method is carried out by direct observation. Mites were taken from the surface of mango leaves later in preservation with several levels of concentration of alcohol, and polyvinyl laktofenol. Then, observed under a microscope and documented for identification purposes. Mites on the leaf surface of manalagi mango (Mangifera indica) found two species, it is Oligonychus sp. and Oligonychus ilicis (Family: Tetranychidae, Superfamily: Tetranychoidea). Oligonychus sp. hallmark is rounded body shape like a spider, with a body is transparent and there are two long seta on posterior part. While Oligonychus ilicis has a characteristic elongated rounded body shape, red, and there is a short posterior seta. Oligonychus sp. and Oligonychus ilicis live as parasites on the surface of mango leaves that can lead to wrinkled leaves, yellow and to fall. Oligonychus life cycle starts from the eggs develop into Nympha and then adult.

Sweet potato serves as a staple food for people in Jayawijaya. Many cultivars of sweet potatoes have been cultivated by Dani tribe in Kurulu as foot for their infant, child and adult as well as feeding especially for pigs. Base on the used of sweet potatoes as food source for infant and child, this study explored 10 different cultivars. As for the leaf morphology, it was indentified that the mature leaves have size around 15 � 18 cm. general outline of the leaf is reniform (40%), 60% have green colour leaf, 50% without leaf lobe, 60% of leaf lobes number is one, 70% of shape of central leaf lobe is toothed. Abazial leaf vein pigmentation have purple (40%), and petiole pigmentation is purple with green near leaf (60%), besides its tuber roots, sweet potatoes are also harvested for its shoots and green young leaves for vegetables.
