“…The mango trees are not only planted in the villagers' yards but also planted in the moor (a former rain-fed rice field) during the dry season, in the office or elementary schoolyards. According to Normand et al Although mango tree is adapted to dry environments experiencing water stress and high evaporative demand, the expected increase of drought and vapor pressure deficit (VPD) would hurt photosynthesis because of the rapid stomatal closure of the mango tree when the climatic demand increase [6].Based on the result of the observation there were some moors planted with the mango trees around ten up to 100 trees, and there were some trees beside and behind the district office of Tirto, in the village office yard, and the elementary schoolyards.…”

In general, people planted mango trees for reforestation and did not take care of them because it was inefficient at both time and cost. That condition attracted capital owners' attention by leasing and profit-sharing transactions or called as "mango spraying agreement." This article analyzes such practice in Pekalongan Regency.The study used an empirical juridical approach and the specification of descriptive analysis. The study found that the mango spraying agreement is practiced in the form of lease and profit-sharing contracts should be made by oral agreement (without written documents), without witnesses, and within a period of once harvest. Moreover, the lessee paid the rent, maintained, protected, and entitled to collect them. The profit-sharing agreement was divided into the forms of maro and metal. The type of maro the contribution and the harvest were split into two, i.e., between the owner and the cultivator. On the other hand, the form of merely applied the profit-sharing between the owner, the capital owner, and the cultivator by the agreement, respectively. Then, the mango spraying agreement had provided benefits of increasing the production of mangos both in quality and quantity in Pekalongan regency. It ultimately had an impact on improving the community economy as the activity involved many parties in the community (owners, capital owners, sprayers, cultivators, shippers, and collectors) which particularly respectively obtained financial benefits and generally improved the economy of the coastal area's community in Pekalongan regency.

“…The number of mango trees per cultivar per orchard was significantly different between orchards (Figure 5a), and the frequency of load index categories depended on the orchard (Chi-squared, p-value < 0.001) (Figure 5c). Some orchards (1,5,10,12,13) had high proportions of trees with 'high' and 'medium' load indices, while others (6,8,9,11) had high proportions of 'low' and 'null' indices. Additionally, orchards displayed significant discrepancies in tree structures (Chi-squared, p-value < 0.001 for all tree structure parameters).…”

“…One way to estimate yield in the field is to use crop models that evaluate plant yield responses to its genotype, environment, and cropping system [8]. However, models of tree crops are sparse, and there is currently no complete mango crop model forecasting production [9]. Indeed, mango trees are characterized by strong vegetative and reproductive asynchronisms and irregular bearings explained by interplays between several endogenous (cultivar, temporal phenology, etc.)…”

Mango Yield Mapping at the Orchard Scale Based on Tree Structure and Land Cover Assessed by UAV

et al. 2018

In the value chain, yields are key information for both growers and other stakeholders in market supply and exports. However, orchard yields are often still based on an extrapolation of tree production which is visually assessed on a limited number of trees; a tedious and inaccurate task that gives no yield information at a finer scale than the orchard plot. In this work, we propose a method to accurately map individual tree production at the orchard scale by developing a trade-off methodology between mechanistic yield modelling and extensive fruit counting using machine vision systems. A methodological toolbox was developed and tested to estimate and map tree species, structure, and yields in mango orchards of various cropping systems (from monocultivar to plurispecific orchards) in the Niayes region, West Senegal. Tree structure parameters (height, crown area and volume), species, and mango cultivars were measured using unmanned aerial vehicle (UAV) photogrammetry and geographic, object-based image analysis. This procedure reached an average overall accuracy of 0.89 for classifying tree species and mango cultivars. Tree structure parameters combined with a fruit load index, which takes into account year and management effects, were implemented in predictive production models of three mango cultivars. Models reached satisfying accuracies with R2 greater than 0.77 and RMSE% ranging from 20% to 29% when evaluated with the measured production of 60 validation trees. In 2017, this methodology was applied to 15 orchards overflown by UAV, and estimated yields were compared to those measured by the growers for six of them, showing the proper efficiency of our technology. The proposed method achieved the breakthrough of rapidly and precisely mapping mango yields without detecting fruits from ground imagery, but rather, by linking yields with tree structural parameters. Such a tool will provide growers with accurate yield estimations at the orchard scale, and will permit them to study the parameters that drive yield heterogeneity within and between orchards.

“…Mango (Mangifera indica L.) is the fifth most cultivated fruit in the world (Normand et al, 2015) and is considered the king of tropical fruits (Tharanathan et al, 2006), being cultivated in more than 100 countries (Mitra, 2016). The total world fruit production in 2017 was 50.6 million t and India as the main producer country with about 40 % of the total mango produced worldwide (FAO, 2019).…”

Effect of nitrates alone or with paclobutrazol on flowering induction and production in mango cv. Tommy Atkins//Efecto de nitratos solos o con paclobutrazol en la inducción floral y producción en mango cv. Tommy Atkins

The flowering induction in mango (Mangifera indica L.) orchards is an agricultural practice carried out on tropical regions to obtain fruits out-of-season looking to reach better sale prices. The objective of this research was to evaluate the effect of potassium (PN), ammonium nitrate (AN) and paclobutrazol (PBZ) on flowering induction and fruit production in mango cv. Tommy Atkins. The experiment included fourteen treatments with 2, 4, and 6 % PN, and 2, 3 and 4 % AN applied in combination with PBZ (1 g of a.i. m-1 of canopy diameter), paclobutrazol alone (1 g of a.i. m-1 of canopy diameter), and a control (water), which were arranged in a completely randomized design with three replicates. Results show that floral induction and fruit production were improved: PBZ followed by foliar application PN 2 %, 4 % or 6 % induced flowering 16 days after treatments. Likewise, the major number of emerged panicles were obtained with PBZ + PN 6 %. An increase on fruit weight and size reduction was observed at harvest. PBZ followed by foliar application of nitrates induced flowering and enhanced the number developed panicles in mango cv. Tommy Atkins.RESUMENLa inducción floral en mango (Mangifera indica L.) es una práctica agrícola común en regiones tropicales, tendiente a obtener frutos fuera de temporada para lograr mejores precios de la cosecha. Este trabajo tuvo como objetivo evaluar el efecto de tratamientos de nitrato de potasio (PN), nitrato de amonio (AN) y paclobutrazol (PBZ) sobre la inducción floral y producción de fruto en mango cv. Tommy Atkins. Los tratamientos con PN al 2, 4, y 6 % y AN al 2, 3 y 4 % fueron aplicados solos o combinados con PBZ (1 g de i.a. m-1 de diámetro de copa), PBZ solo y un testigo (agua) bajo un diseño completamente al azar, con tres repeticiones. Se midieron variables de inducción floral y producción de fruto. Los resultados muestran que aplicación foliar de PBZ seguida de PN (2 %), (4 %) o (6 %) indujeron floración 16 días después del tratamiento. El mayor número de panículas emergidas se obtuvieron con PBZ + PN 6 %. Se observó una reducción de peso y tamaño de fruto a la cosecha. El PBZ seguido de aplicaciones foliares con NP y AN induce floración y aumenta el número de panículas desarrolladas en mango cv. Tommy Atkins.
