“…Irrigation for forage cactus crops in the irrigated perimeter of Ceraíma and in the Valley of Iuiu (Table 2) has contributed to increase their yield (FONSECA et al, 2019) to values higher than those found for agroecosystems with low fertility soils and water deficit, such as Riacho de Santana (Table 1). Forage cactus crops in Riacho de Santana had the lowest yield, with a mean of 15 Mg ha -1 year -1 ( Table 6).…”

“…The structural characteristics of four randomized plants in each of the three replications (12 plants) of each of the 20 properties were evaluated, totaling 240 plants (GUIMARÃES et al, 2019). These characteristics consisted of: cladode thickness (CT), determined in the middle part of all cladodes; cladode width (CW), measured in the highest widest part of the cladode; cladode length (CL), measured in the longest part of the cladode; total number of cladodes (TNC) per plant; plant height (PH), distance from the top of the highest cladode and the soil; cladode area (CA) [CA (cm 2 ) = CC x LC x 0.693); 0.693 is the correction factor due to the elliptical form of the cladode (PINTO et al, 2002)]; total cladode area (TCA); cladode area index (CAI), which is the TCA of both sides of the cladodes divided by the area used by the plant (AUP) (m 2 of cladode per m 2 of soil).…”

The adaptation capacity of forage cactus (Opuntia ficus-indica Mill) plants to edaphoclimatic conditions and plant responses to changes in management systems contribute to increase the use of this species in agriculture and the exploration of its productive potential in semi-arid regions. The objective of this work was to evaluate the structural characteristics and cladode yield of forage cactus plants grown under different agroecosystems in the semi-arid region of Bahia, Brazil. Structural characteristics of plants and soils attributes were analyzed. The traditional information on the crop management and its correlations with cladode yield were used to identify the best yield indexes, considering the peculiarities of each agroecosystem. Plant height, cladode thickness, and number of cladodes of the forage cactus plants evaluated were less affected by the agroecosystem than by the production systems. Cladode width, length, and area were more affected by the agroecosystems. The forage cactus crop yields, expressed by the annual cladode fresh matter yield, were positively correlated with the plant structural characteristics: plant height and thickness, and cladode width and length. The cladode weight per plant and fresh matter yield per area were the yield components most affected by the management system adopted by traditional producers.

“…According to Fonseca et al (2019), an important physiological characteristic is the cladode area index, since the higher the CAI is, the larger the area for the absorption of photosynthetically active radiation and, consequently, the greater the crop yield. Among the factors that affect the CAI, the nutritional status of the plant stands out.…”

This study aimed to evaluate the yield and survival rate of 'Gigante' cactus pear (Opuntia fícus indica) cultivated with regulated deficit irrigation (RDI) using wastewater under semiarid soil and climatic conditions. The experiment was carried out between October 2015 and August 2017 at Instituto Federal Baiano, campus Guanambi, Brazil. The treatments were as follows: no fertilization and no irrigation (T1); no fertilization and RDI with wastewater (0.6 L plant-1 week-1) (T2); no fertilization and RDI with wastewater (1.2 L plant-1 week-1, applied once a week) (T3); no fertilization and RDI with wastewater (1.2 L plant-1 week-1, divided into two applications per week) (T4) with organic fertilization (60 Mg ha-1 of bovine manure) and RDI with common water (1.2 L plant-1 week-1) (T5) and with organic fertilization (60 Mg ha-1 of bovine manure) and no irrigation (T6). The treatments were arranged in a randomized complete block design with five replicates. Based on the results, we concluded that (i) regulated deficit irrigation using wastewater increased the productivity of 'Gigante' cactus pear when compared to the rainfed crop and (ii) the application of 0.6 L plant-1 week-1 was sufficient to increase the survival rate of 'Gigante' cactus pear under prolonged drought conditions.

“…Apesar desta boa adaptabilidade no semiárido do nordeste, alguns estudos vêm mostrando que quando a precipitação pluvial local não atinge os níveis considerados ideais, faz-se necessário o uso de irrigação suplementar para atender as necessidades hídricas da palma forrageira, sendo uma ótima opção para incrementar o rendimento da cultura, onde promove melhorias em características relacionadas à sua produtividade, como crescimento da planta, número de cladódios e índice de área do cladódio (Queiroz et al, 2015;Amorim et al, 2017;Barbosa et al, 2017a;Cruz Neto et al, 2017;Silva et al, 2017a;Lima et al, 2018b;Fonseca et al, 2019).…”

A irrigação suplementar pode ser uma técnica promissora para o aumento da produção da palma forrageira, contudo, depende da evapotranspiração (ET). A irrigação e a ET estão estritamente relacionados com a produtividade das culturas (P), de modo que a relação entre P e ET resulta na eficiência no uso de água (EUA). Assim, objetivou-se avaliar P, ET e EUA em palma, sob irrigação suplementar. O experimento foi conduzido em campo, com palma submetida a irrigação por gotejamento com intervalos de reposição de água no solo de 7 (T7), 14 (T14) e 21 (T21) dias, mais o tratamento de sequeiro (T0), em blocos ao acaso, com 4 repetições. O crescimento da palma foi monitorado por meio da medição da largura (LC), do comprimento (CC), da área (AC), do índice de área (IAC) e da espessura dos cladódios (EC). Ao longo do ciclo da cultura também foram monitoradas as condições meteorológicas. A ET foi obtida como termo residual da equação do balanço hídrico. Os tratamentos não tiveram efeitos significativos nas variáveis biométricas e na produtividade da palma forrageira. A menor ET foi obtida no T0 (406,1 mm total e 1,7 mm d‑1), sendo que o T7 apresentou a maior ET (664,4 mm total e 2,8 mm d-1). A maior EUA (392,8 kg MF ha-1 mm-1) foi obtida no tratamento sob sequeiro (T0). Com base na produtividade e na EUA da palma forrageira, recomenda-se, para as condições do município de Garanhuns, que o cultivo da mesma seja realizado sob condições de sequeiro.Effect of the Supplemental Irrigation on Yield and Water Use Efficiency of Cactus Pear A B S T R A C TThe supplementary irrigation may be a promising technique to increase forage cactus yield, however, it depends of evapotranspiration (ET). Irrigation and ET are closely related to crop yields (P), so the relationships between P and ET result in water use efficiency (WUE). Thus, the objective was to evaluate P, ET and WUE in cactus pear, under supplementary irrigation. The experiment was conducted under field conditions with cactus pear submitted to drip irrigation with soil water replacement intervals of 7 (T7), 14 (T14) and 21 (T21) days, plus the rainfed treatment (T0), in blocks with 4 replicates. Cactus pear growth, by the measurements of width (WC), length (LC), area (CA), area index (CAI) and thickness of cladodes (CD), was monitored. Meteorological conditions along the cactus pear cycle were monitored. The ET was quantified by the soil water balance method. The treatments had no effects on the biometric variables and yield of cactus pear. ET was lower in T0 (406.1 mm total and 1.7 mm day-1), with T7 showing the highest values of ET (664.4 mm total and 2.8 mm day-1). It was observed that the largest WUE (392.8 kg MF ha-1 mm-1) was in the rainfed treatment (T0). On the basis of the yield and WUE of the cactus pear, it is recommended, for the conditions of the municipality of Garanhuns that the cultivation of the same be carried out under conditions of rainfed.Key words: Soil moisture; evapotranspiration; water balance.
