Mango trees as components of agroforestry sytsems in Mangwende,Zimbabwe

This study investigates the role of mango (Manifera indica L.) within agroforestry systems in Mangwende, Zimbabwe. Eighty two percent of households had mango trees. Neither the degree of natural woodland depletion nor the wealth status of a household had an influence on mango planting. Most mango trees were planted in the homefields. Mango trees provide fruit, firewood, poles, organic matter for soil amendment, living fence post, shade, soil conservation and cattle feed (the rotting fruits). Wealthy and poor households managed mango trees in the same way. Trees were pruned primarily to increase fruit yields and to reduce competition with crops, although prunings were utilised for firewood and poles. The relative importance of different uses of mango trees did not differ among households with different numbers of mango trees or with different wealth status, with fruits universally acknowledged as the most important product. Ninety four percent of households sold mangoes from their farms, but mangoes earned farmers the least income, in comparison with the four most important crops grown in Mangwende. Two thirds of households intercropped mangoes with herbaceous crops. The mangocrop associations were managed to optimise the yields of both crops and mangoes. Mango trees on croplands were widely perceived as having a positive effect on soil fertility and soil moisture and a negative effect on crop yield. About one third of the households used mango litter for soil amelioration, while litter from indigenous woodland was used by most households, especially in gardens.

Performance of mango based agri-horticultural models under rainfed situation of Western Himalaya, India

A total of 15 years of experimentation period (1995–2010) was divided into two phases. In the first phase (1995–2005), five mango based agri-horticultural models (AHM) viz. Mango + cowpea–toria, mango + cluster bean/okra–toria, mango + sesame–toria, mango + black gram–toria and mango + pigeon pea in addition to sole mango plantation (no intercrop) and in second phase (2005–2010), two mango based AHM (mango + colocasia and mango + turmeric) in addition to sole mango (no intercrop) were studied. The mean maximum cowpea equivalent yield (t ha^?1) was harvested from cowpea (1.84) followed by okra (1.21), black gram (1.11), sesame (0.68) and mean minimum with pigeon pea (0.58). The crop yield reduction among the mango based AHM was observed from third year to tenth year. The positive correlation was found between light transmission and intercrops yields amongst all models during both phases. However, the correlation between mango canopy spread and intercrop yields shown negative trends. The yield reduction in intercrops varied from 37.0–52.6 % during first phase and 20.6–23.5 % during second phase of experimentation compared to sole crop. The results revealed that the fruit based AHM were effective in improving fruit yields of the mango. The mean maximum fruit yield of mango (7.02 t ha^?1) was harvested with cowpea–toria crop rotation followed by black gram–toria (6.59 t ha^?1) and minimum fruit yield (5.76 t ha^?1) realized with sole mango tree during first phase (1999–2005). Likewise, mean maximum fruit yield (13.71 t ha^?1) from mango tree was obtained in the turmeric block followed by (13.00 t ha^?1) in colocasia block and minimum fruit yield with sole mango tree (11.86 t ha^?1). All the treatments of AHM recorded higher soil moisture as compared to sole mango plantation during both phases. The moisture retention under different AHM was in the order of cowpea (13.32 cm) > black gram (13.29 cm) > pigeon pea (13.27 cm) > okra (12.42 cm) > sesame (12.17 cm) > sole mango (11.62 cm) during first phase, whereas moisture retention was observed in the order of turmeric (14.20 cm) > colocasia (14.01 cm) > sole mango (12.60 cm) during second phase. The cowpea–toria crop rotation with mango gave maximum benefit: cost ratio followed by okra–toria under rainfed conditions. Besides economic viability of cowpea–toria with mango, this system had improved tree growth as well as fruit yield of mango. In the second phase, mango + turmeric yielded more benefit than mango + colocasia system. In the first phase, the mango + cowpea–toria system improved organic carbon, total nitrogen, phosphorus, potash and reduced pH by 49.0, 56.3, 48.6, 58.5 and 11.6 %, respectively as compared to initial values whereas mango + turmeric system increased organic carbon, nitrogen, phosphorus, potash and reduction in pH by 51.0, 45.0, 29.7, 29.0 and 3.4 %, respectively over initial values within soil depths of 0–30 cm during second phased. Mango based AHM is recommended for adoption with selective intercrops up to 15 years of age of mango plantation for multiple outputs and good economic viability without impairing site fertility.

A biochemical model of photosynthesis for mango leaves: evidence for the effect of fruit on photosynthetic capacity of nearby leaves

Variations in leaf nitrogen concentration per unit mass (Nm) and per unit area (Na), mass-to-area ratio (Ma), total nonstructural carbohydrates (Ta), and photosynthetic capacity (maximum carboxylation rate, electron transport capacity, rate of phosphate release in triose phosphate utilization and dark respiration rate) were studied within the digitized crowns of two 3-year-old mango trees (Mangifera indica L.) on La Réunion Island. Additional measurements of Nm, Na, Ma, Ta and photosynthetic capacities were performed on young, fully expanded leaves of 11-year-old mango trees. Leaves of similar gap fractions were taken far from and close to developing fruits. Unlike Nm, both Na and Ta were linearly correlated to gap fraction. Similar relationships were found for all leaves whatever their age and origin, except for Ta, for which we found a significant tree effect. Photosynthetic capacity was nonlinearly correlated to Na, and a unique relationship was obtained for all types of leaves. Photosynthetic acclimation to light was mainly driven by changes in Ma, but allocation of total leaf N between the different photosynthetic functions also played a substantial role in acclimation to the lowest irradiances. Leaves close to developing fruits exhibited a higher photosynthetic capacity than other leaves, but similar Ta. Our data suggest that Ta does not control photosynthetic capacity in mango leaves. We used the data to parameterize a biochemically based model of photosynthesis and an empirical stomatal conductance model, allowing accurate predictions of net photosynthesis of leaves in field-grown mango trees.
