“…Soursop is a tropical fruit crop with prospects of production and marketing in almost all the Brazilian territory, especially in the Northeastern semi-arid region, where the edaphoclimatic conditions are favorable to its exploitation (Silva et al, 2013).…”

Nitrogen (N) fertilization has been tested for the mitigation of salt stress in some species including fruit crops. However, special attention should be paid to the source of N, due to the different compositions and saline indices of the fertilizers, particularly when irrigation is conducted using waters with salinity levels that are restrictive to agriculture. Thus, this study evaluated the effect of fertilization with N sources on the growth and gas exchanges of soursop irrigated with saline water after transplanting. The experiment was carried out in greenhouse at the Center of Technology and Natural Resources of the Federal University of Campina Grande, and treatments were arranged in randomized blocks, in 4 x 4 factorial scheme, corresponding to electrical conductivity of water - 0.5, 1.1, 2.5 and 3.5 dS m-1, and the N sources urea, ammonia sulfate, calcium nitrate and potassium nitrate, with three replicates. Growth and gas exchanges of soursop at 110 days after transplanting were not influenced by either the interaction between water salinity and N sources or the individual action of N, but were inhibited by the increase in water salinity from 0.5 dS m-1. Increasing water salinity inhibited stomatal opening and carboxylation in the leaves.

“…Under irrigated conditions, fruit yield was increased from 34.7 to 45.6 t ha -1 in the first harvest and from 57.7 to 70.3 t ha -1 in the second harvest in the soil without mulching and mulching with sisal residues, respectively (Figure 4). These values are higher than the yield of 31.8 t ha -1 obtained in irrigated soursop (Silva et al, 2013) and exceed the yields of 31.0 and 46.3 t ha -1 obtained in irrigated soursop without mulching and mulching with sisal residue, respectively (Cavalcante et al, 2016).…”

“…In the semiarid areas of Brazil, the low and irregular rainfall, allied to the high evaporative demand, makes soursop (Annona muricata L.) cultivation highly dependent on irrigation (Silva et al, 2013). To reduce the evaporative loss of water in the soil, the use of mulch can benefit crops both with and without irrigation, keeping the soil moist, less heated, and reducing the effects of solar radiation and air temperature on soil water evaporation (Bakshi et al, 2015;Sharma & Bhardwaj, 2017).…”

Irregular rainfall in the semiarid region of Brazil and in the world exerts a limiting action on agricultural production, in general, including fruit species. Under these conditions, irrigation is the input that keeps the production system both economically and socially viable. This study was carried out from 2012 to 2014, in the municipality of Remígio, Paraíba State, Brazil, aiming at evaluating the production of ‘Morada’ soursop cultivated under rainfed and irrigated conditions, in soil with and without mulch, in two harvests. The treatments were distributed in randomized block design with three replicates in a 2 × 3 × 2 factorial scheme, corresponding to non-irrigated plants (0 mm water depth) and plants irrigated weekly (17.2 mm water depth) in soil without mulching, with cover crop residues, and with a sisal bagasse mulch in the 2012/2013 and 2013/2014 crop years. In the soil without mulching, irrigation increased yield from 5.3 to 34.7 t ha-1 in the first harvest and from 9.4 to 57.7 t ha-1 in the second harvest. The association between irrigation and mulch with sisal residue promoted the highest yield. The use of mulch of sisal residue increased the number and mean mass of fruits, production per plant and yield of ‘Morada’ soursop compared to the soil without mulch and covered by crop residues.

The uses of humic substances and organic residues for soil mulching have been more common during last years. This way, an experiment was carried out to evaluate the fruit quality and yield of guava cv. Paluma as a function of humic substances and organic soil mulching in Brazil. The experiment was performed from January 2012 to June 2013 (first trial) and from July to November 2013 (second trial) using a randomized blocks with treatments distributed in a factorial arrangement (5 × 2 × 2) of five humic substances doses (0, 10, 20, 30 and 40 mL of Humitec plant -1 ), two organic mulching use (with and without organic mulching) and two consecutive harvests, with four replications of two plants each. Humic substances enhance fruit production more efficiently in guava plants grown without soil mulching. Guava fruit production increases from the first to the second harvest. Fruit quality for titratable acidity, soluble solids, vitamin C and soluble solids/titratable acidity ratio is adequate independently of soil mulching use. Humic substances improve fruit quality of guava cv. Paluma. Under soil and climate conditions, and considering the first two production cycles of guava, it is possible to recommend about 20 mL L -1 of humic substances for production of high quality guava fruits.
