In 2014-2018, the yield, fruits, and survival of trees planted in 1997 were evaluated in a randomized complete block design. Yield was assessed using annual fruit production, yield efficiency, and the alternate bearing index. Tree survival was considered the percentage of plants that remained alive until 2018. Fruit quality was evaluated by physicochemical attributes. 'Cravo' confirmed its good yield performance. Despite the lower number of trees, the 'Mazoe' rough lemon rootstock induced the highest fruit yield. The 'Cravo' x 'Cleópatra' hybrid and 'Volkameriano' lemon favored the highest trees survival, whereas 'Indio' citrandarin and 'Cravo' lime resulted in intermediate levels. The 'San Diego' and 'Riverside' citrandarins induced shorter tree with a high yield efficiency and a higher alternate bearing index, respectively. Fruits with less juice and mass were induced, respectively, by 'Riverside' citrandarin and 'Volkameriano' lemon. It can be concluded that the 'Mazoe' rootstock induces a higher fruit yield and 'Cravo' x 'Cleópatra' and 'Volkameriano', a greater survival. In addition, all rootstocks, except 'Riverside' and 'Volkameriano', induce fruit that meet the minimum quality requirements.

The cultivars showed differences in proline and chlorophyll contents, plant height, number of leaves and branches, canopy area and root production, however they did not differ on photosynthetic rates. Cultivars 'Tianguá' and '9783-13' presented lower root yield, whereas 'BRS Tapioqueira' and 'Irará' had the highest root yield. Few leaves coupled with the highest water use efficiency for CO 2 assimilation was found in 'BRS Kiriris' in contrast to 'BRS Jarina' and '9783-13'. 'BRS Caipira' had high proline content in both Umbaúba and Frei Paulo areas, traits usually associated to drought tolerance, that contribute to the adaptation. It is also important to consider that cultivar 'BRS Caipira' was the first to present increase in chlorophyll content after extended period of drought, that indicates a faster recovery after dry season. Furthermore, the results indicated that the most adapted cultivars for cultivation in this area are 'Irará', 'BRS Tapioqueira', 'BRS Kiriris' and 'BRS Caipira'.

Therefore, assessing new rootstocks for 'Pera' in this region is pivotal for diversification purposes, potentially leading to increased competitiveness, yield and fruit quality. In this study, vegetative growth, productive performance, pest attack and fruit quality of 'Pera', grafted on five rootstocks, were assessed over 10 years in Northeast Brazil. The trifoliate hybrid HTR-051 conferred the highest yield efficiency to 'Pera', while 'Red Rough' lemon and LVK x LCR-010 induced precocity, with yields exceeding 9400 kg ha −1 in the first harvest, as well as the highest cumulative yields. 'Red Rough' lemon, LVK x LCR-010 and HTR-051 were notable for imparting high weight and total soluble solids to 'Pera' fruit. Regarding pests, the highest densities of citrus rust mite Phyllocoptruta oleivora were found on the fruit of 'Pera' grafted on LVK x LCR-010, despite low densities of this arthropod over the sampling period. Altogether, our results highlight 'Red Rough' lemon and LVK x LCR −010 as superior rootstocks for excelling in productive performance and fruit quality. In addition, HTR-051 manifests as an excellent option for high-density orchards because it induces dwarfism and high production efficiency.

It is an activity with economic, social and environmental risks. The intercropping has been used as a form to reduce these risks. In this work the yield of tomato in sole crop and intercropping with Foeniculum vulgare, Mentha piperita, Ocimum basilicum and Ruta graveolens was evaluated. The monocrop of tomato and its intercropping was evaluated with aromatic plants in a complete randomized design, with five treatments and four blocks. We evaluated height, canopy area, production, yield and land equivalent ratio. On the population density adopted, the F. vulgare (fennel) presented greater height and canopy area, and caused significant reduction on total production of tomato, from 12.23 kg, in monocrop, to 7.88 kg, when intercropped with fennel. However, intercropping with fennel contributed to a lesser loose caused by fruits borer (24%). The greatest loose caused by fruits borer occurred in monocropping and in intercropping with M. piperita (peppermint). Intercropping with Ruta graveolens (rue) resulted significant increase of commercial production of fruits, about 26%. The relative yield of tomato was greater in intercropping with rue (13.6 t ha-1), followed by intercropping with peppermint (9.8 t ha-1) and with O. basilicum (basil) (9.1 t ha-1), and lesser on intercropping with fennel (6.4 t ha-1). These results showed that the intercropping with rue was more advantageous than others producing more fruits. Among the studied aromatic plants, basil presented the highest yield (96.5 t ha-1). The tomato intercropping with aromatic cultures permits better use of land and higher yield, mainly when intercropping with rue. All aromatics plants evaluated represent an alternative source of gain.

The present study aimed to determine alternative rootstocks to 'Rangpur' lime for 'Pera' sweet oranges grown on tropical hardsetting soils with greater potential tolerance to water deficit. Six citrus scion/rootstock combinations were grown during eight years in an orchard established in Sergipe, Brazil. The tree height, number of fruits per plant, cumulated fruit yield, leaf proline content and survival rate of trees were evaluated between 6 th and 8 th year after planting. Greater rate of tree loss occurred among the sweet orange onto 'Orlando' tangelo, which also induced the lowest cumulative fruit yield. After prolonged water deficit, moderate to high proline content was found in trees grafted on Sunki of Florida mandarin × C13 citrange-012° (TSKFL × CTC13-012), 'Orlando' tangelo, 'Indio' and 'Riverside' citrandarin. Conversely, after a short water deficit during the wet season, trees on 'San Diego' citrandarin and Rangpur lime clone of Centro Nacional de Pesquisa Mandioca e Fruticultura-CNPMF 03 'Rangpur' lime showed higher proline content. Trees onto TSKFL × CTC13-012 and 'Indio' also induced the greatest accumulated fruit yield at the 8 th year after planting. It is assumed that 'San Diego' and CNPMF 03 'Rangpur' induce response more quickly to water deficit, whereas TSKFL × CTC13-012 and 'Indio' are less susceptible to prolonged deficit. Therefore, trees on 'San Diego' and Indio citrandarin, CNPMF-03 'Rangpur' lime, TSKFL × CTC13-012 hybrid present greater potential to tolerate water deficit and produce more fruits on the hardsetting soils of the coastal tablelands of the Brazilian Northeast.

An experiment was installed to test ten rootstock for 'pineapple' sweet orange: 'Santa Cruz' Rangpur lime, 'Red Rough' Lemon, 'Orlando' Tangelo, 'Sunki Tropical' Mandarin, 'Swingle' citrumelo, the citrandarins 'Indio' and 'Riverside' and the hybrids HTR-051, LVKxLCR-010 and TSKxCTTR-002. The trial was installed in 2008 in the municipality of Umbauba in Sergipe. The experimental design was complete randomized blocks with four replications and two plants per plot. Plant spacing was 6 x 4 m which corresponds to 416 plants per hectare and the orchard was rainfed and followed conventional management. The following agronomical parameters were evaluated: vegetative growth, drought tolerance, yield and physico-chemical quality of fruits as well as the abundance of phytophagous mites. Both hybrids LVK x LCR-010 and TSKC x CTTR-002 and the 'Santa Cruz' rangpur lime bestowed higher tolerance to the dry period on the 'Pineapple' orange tree, by comparison with higher water deficit susceptibility conferred by the 'Orlando' tangelo and the 'Swingle' citrumelo. Rootstocks HTR-051, 'Riverside' citrandarin, 'Swingle' citrumelo and TSKC x CTTR-02 induced plants to remain small and, thus, showed aptitude for culture densification. Cumulative yield of the 'Pineapple' orange was higher on rootstocks 'Red Rough' lemon and 'Santa Cruz' Rangpur lime, the hybrid LVK x LCR-010 and 'Sunki Tropical'. Yield efficiency was not influenced by the rootstocks. Physico-chemical quality of fruits of 'Pineapple' orange is affected by the rootstocks and meets the requirements of juice industries. Regarding plant resistance, the rootstocks did not influence the population density of mites P. oleivora, E. banksi and T. mexicanus on 'Pineapple' oranges. Results show that both rootstocks 'Red Rough' lemon and 'Santa Cruz' rangpur lime conferred high regularity to 'Pineapple' orange trees in citrus growing regions in Bahia and Sergipe states.

The diversification of citrus orchards through the introduction of new scion-rootstocks combinations is an important strategy to reduce the risks associated with these constraints. Three experiments aiming at identifying appropriate scionrootstock combinations for enhancing genetic diversification in citrus orchards under rainfed conditions in tropical hardsetting soils were established in Sergipe state in 2008. In each one, a different sweet orange ('Sincora', 'Valencia Tuxpan' and 'Pineapple') was grafted on six rootstocks ('Santa Cruz' Rangpur lime, 'Red Rough' lemon, 'Orlando' tangelo, 'Sunki Tropical' mandarin, HTR-051 and VKLxRPL-010 hybrids). After eight years the experiments were evaluated for plant development, yield performance and fruit quality. In general, all sweet oranges grafted on 'Red Rough' lemon showed great development and cumulative yield as does with 'Santa Cruz' Rangpur lime, with the later showing better fruit quality as an advantage. Inversely, HTR-051 hybrid displayed low yields despite high yield efficiency, for this rootstock induces dwarfism. 'Sunki Tropical' mandarin brought high yields of medium quality fruits, while the VKLxRPL-010 hybrid induced productive precocity, especially for 'Sincora' sweet oranges. Based upon these results, all tested scions grafted on 'Red Rough' lemon and 'Santa Cruz' Rangpur lime, followed by 'Sunki Tropical' mandarin are indicated for genetic diversification of groves, when planted at conventional density. On the other hand, the hybrid HTR-051 seems to have great potential for high density orchards, since it shows high yield efficiency and good quality of fruit.

The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo Santa Cruz' lime, 'San Diego' citrandarin, and the hybrids HTR-051 and LVK x LCR-010 conferred lower-cumulated yields to 'Jaffa'. The rootstocks did not influence the population levels of the evaluated mites. 'Sunki Tropical' mandarin, 'Cravo Santa Cruz' lime and 'Rugoso Vermelho' lemon stand up as excellent rootstock options for 'Jaffa' sweet orange in the Northeastern Brazil.

Thirteen cultivars were sown in experiments set in three sites in the Brazilian Northeast. Proline content was determined on leaves from plants at the R4-R5 stage. Significant differences among cultivars occurred only where water availability was lower. Proline averages ranged from 3.47 to 17.41 µg g-1. The sunflower cultivars BRS387, BRS323, and BRS324 showed the greatest proline contents with 54.74, 46.27, and 35.16 µg g-1 , respectively. These are the cultivars that accumulate more proline under conditions of a severe water deficit.

In this study, a field experiment was done in the semi-arid region of Sergipe state, Brazil, to evaluate the performance of fennel-bean intercrop under organic management, using a completely randomized block design with six replications and four treatments (fennel monocrop and fennel intercropped (additive model) with two cultivars of beans (Phaseolus vulgaris) and one cultivar of cowpea (Vigna unguiculata). Fennel plants were obtained from seeds and transplanted into the field at the beginning of the rainy season in June, while seeds of the beans and cowpea were being sown. Umbels of the fennel were harvested in January, 210 days after transplanting the fennel into the field. The fresh and dry mass of umbels, absolute and relative yield, land equivalent ratio (LER) and essential oil content were improved under the intercrop with cowpea and one cultivar of bean. No significant differences were detected on height and canopy areas among treatments, but any decrease in yield of fennel plants associated with intercrops with cowpea or bean were small. The intercrops studies confirmed the viability of intercropping fennel with cowpeas and beans.

New varieties should meet high drought tolerance with water deficit, cohesive soils, resistance to citrus diseases and inducing high production of fruit. In this work, the performance of 'Pera' sweet orange was evaluated on 'Tropical Sunki' mandarin and 27 hybrid citrus rootstocks in Umbaúba, Sergipe. A local selection of the 'Rangpur' lime was the control. Planting was in 2013 at tree spacing of 6.0 × 3.0 m, without irrigation. Tree size, fruit yield and quality, tree survival rate and graft-compatibility were assessed until 2019. Experimental design was completely randomized blocks with 29 treatments, three replicates and four plants in the plot. Two selection indices were applied to the data to assist in decision making. The 'Tropical Sunki' mandarin induced similar cumulative fruit yield in relation to the 'Rangpur' lime, suggesting a good drought tolerance of the former rootstock. The TSKC × (LCR × TR)-073 induced slightly lower productivity, compensated by higher productive efficiency and higher concentration of soluble solids, whereas LCR × TR-001 and HTR-166 were highly efficient dwarfing rootstocks. The multiplicative and the rank sum indices showed high correlation, both classifying 'Tropical Sunki' mandarin, 'Santa Cruz Rangpur' lime, LVK × LCR-010 and-038, HTR-127, in addition to the three aforementioned hybrids, as superior to the local selection of 'Rangpur' lime.
