ABSTRACT The objective of this study was to evaluate combinations of coriander and salad rocket cultivars in bicropping systems intercropped with carrot cultivars in strips under the conditions of Mossoró-RN. The work was conducted at the Experimental Farm Rafael Fernandes from July to December 2014. The experimental design was a randomized complete block design with four replications and treatments arranged in a factorial design with additional treatments of type 2 x 2 x 2 + 2. The treatments consisted of the combinations of two coriander cultivars (Verdão and Português) and two rocket cultivars (Cultivada and Folha Larga), intercropped with two carrot cultivars (Brasília and Esplanada) plus two additional treatments, where the first are the cultivars in monocropping and the second the types of cropping (single and intercropped). We evaluated fresh and dry shoot mass in coriander and rocket and fresh and dry shoot mass as well as dry root mass, commercial and total root productivity, and classified root productivity in carrot. In the intercropping systems we evaluated land equivalent ratio, productive efficiency index, and score of the canonical variable, besides the indicators of economic efficiency (gross income, net income, rate of return and profit margin). Highest agroeconomic efficiency in intercropping systems was achieved with the combination of the coriander cultivar 'Verdão' and the rocket cultivars 'Folha Larga' or 'Cultivada' as well as the carrot cultivars 'Brasília' or 'Esplanada'. Regardless of the tested cultivar combinations, systems with coriander and salad rocket intercropped with carrot showed higher efficiency than monocropping systems.

ABSTRACT This study aimed to evaluate combinations of cowpea-vegetable cultivars with carrot cultivars in a strip-intercropping system fertilized with roostertree. The work was conducted at the Experimental Farm "Rafael Fernandes" of the Universidade Federal Rural do Semi-Árido (UFERSA) during September 2013 to March 2014. The experimental design was a randomized complete block with four replications and treatments arranged in a factorial 4 x 2 scheme, resulting from the combination of four cowpea -vegetable cultivars (BRS Tumucumaque, BRS Cauamé, BRS Guariba and BRS Itaim) with two carrot cultivars (Brasilia and Alvorada). The characteristics evaluated in cowpea-vegetables were: number of green pods per area, productivity and dry weight of green pods, number of grains per pod, productivity of grains, weight of 100 grains, and dry weight of green grains. In the carrot cultivars, we evaluated total, commercial, and classified productivity of roots. The cultivar combinations were evaluated in terms of land equivalent ratio, productive efficiency index, score of the canonical variable, as well as indicators of gross and net income, rate of return, profit margin, and modified monetary advantage. The intercropping system using the cultivars BRS Guariba (cowpea) and Alvorada (carrot) achieved highest agronomic/biological efficiency. Highest economic efficiency was achieved with the combination BRS Tumucumaque (cowpea) and Brasilia (carrot).

ABSTRACT The objective of this research was to evaluate combinations of cultivars of coriander and arugula in two croppings with cultivars of carrot in a strip-intercropping system. The study was conducted from November 2014 to March 2015. The experimental design was a randomized complete block in a 2 x 2 x 2 + 2 factorial scheme, with four replications. The treatments consisted of the combination of two cultivars of coriander (Verdão and Português) with two cultivars of carrot (Brasília and Esplanada) and two cultivars of arugula (Cultivada and Folha Larga) in a strip-intercropping system plus two additional treatments, where the first represents the cultivars in monocropping and the second the cultivation types (monocropping and intercropping). The characteristics evaluated in the coriander and arugula were green mass yield and shoot dry mass. The following were evaluated in carrot: shoot dry mass, dry mass of roots, total and commercial productivity, and classified productivity of roots. In the intercropping system, the agronomic indices of land equivalent ratio, productive efficiency index, and score of the canonical variable were evaluated. The economic efficiency indicators determined were gross and net income, rate of return, profit margin, monetary advantage, and modified monetary advantage. There was no significant interaction among the cultivars of coriander, carrot, and arugula for coriander and arugula green mass yields, and for total and commercial productivities of carrot roots. The best polyculture was of that involved in the cultivars ―Português,‖ ―Esplanada,‖ and ―Cultivada‖.

ABSTRACT The objective of this study was to evaluate the agro-economic efficiency of the intercropping of carrot with cowpea-vegetable under different spatial arrangements and population densities in the semi-arid conditions of the Brazilian Northeast. The study was conducted at the "Rafael Fernandes" Experimental Farm of the Universidade Federal Rural do Semi-Árido (UFERSA) during the period July 2013 to February 2014. The experimental design was of randomized complete blocks with four replications and treatments arranged in a 3 × 4 factorial scheme, where the first factor consisted of spatial arrangements (2:2; 3:3 and 4:4) and the second factor by population densities of cowpea-vegetables (100, 80, 60 and 40% of the recommended population in sole crop [RPSC]). All treatments were fertilized with roostertree (Calotropis procera [Ait.] R.Br.), which is a spontaneous species of the Caatinga biome. The indices of agronomic efficiency of the intercropping systems assessed were: land equivalent ratio, productive efficiency index and score of the canonical variable. The following economic indicators were also evaluated: gross income, net income, rate of return and profit margin. The agro-economic efficiency of the intercropping system of carrot with cowpea- vegetable was influenced by the spatial arrangements, with the 2:2 arrangements standing out from the others. The greatest agro-economic efficiency of the intercropping of carrot with cowpea-vegetable was obtained in the population density of 100% of the RPSC when the value of the productive efficiency index was 0.75.

Low crop productivity in most marginal uplands is primarily due to poor agro-ecological conditions. There is a need to improve farming practices of upland farmers to improve their quality of life thus, the study was conducted in the marginal uplands of Brgy. Linao, Inopacan, Leyte, Philippines from February to July 2013, to determine the best cropping system that would improve crop productivity and to promote the best cropping system technology to upland farmers. The experimental units were arranged in Randomized Complete Block Design with three replications. The treatments were intercropping (upland rice + mungbean, corn + mungbean) and monocropping (upland rice, corn and mungbean). The growth and yield parameters were not significantly influenced by the cropping systems. Thus, crop growth and development in either intercropping or monocropping schemes were comparable. However, corn + mungbean gave a land equivalent ratio (LER) of 1.53, which means that such cropping system is more productive than growing corn or mungbean as monocrop. On the other hand, growing upland rice alone was more productive than upland rice + mungbean as indicated by a LER of 0.93.Corn + mungbean gave a net income of PhP8,452.18 per hectare.

The region of the Zona da Mata of Minas Gerais stands out in the production of vegetables. To achieve the success in this activity, it is important to choose suitable cultivars and apply irrigation correctly. This study aimed to determine the optimum irrigation depth and evaluate new commercial arugula cultivars in the Zona da Mata of Minas Gerais. The cultivation was carried out in a greenhouse during three cycles with periods of 33 (January 11, 2016 to February 12, 2016), 36 (March 1, 2016 to April 5, 2016), and 36 (April 12, 2016 to May 17, 2016) days. The experimental design was a randomized complete block design with five replications, five irrigation depths (50, 75, 100, 125, and 150% of the crop evapotranspiration-ETc) in the plots, and three arugula cultivars (Antonella, Cultivada, and Folha Larga) in the subplots. A drip irrigation system was used. The parameters evaluated were root depth, root fresh mass, plant water potential, leaf temperature, number of commercial leaves, total number of plants, fresh shoot mass, and water use efficiency. Arugula cultivars did not present differences in their agronomic characteristics. An irrigation depth of the 50% ETc is recommended if the soil moisture is under the field capacity at the beginning of the arugula cycle.

Alternate planting combinations of maize (Zea mays L.) with lima bean (Phaseolus lunatus L.) using wood ash as soil amendments were compared with the sole planting of each crop during the late 2014  and early 2015 planting seasons at the Teaching and Research Farm of the Federal University of Technology, Akure. The experiment in each season adopted three patterns of intercropping using ash as a soil amendment and laid out in a Randomized Complete Block Design (RCBD) with three replications. The experiment comprised 10 treatments: Sole planting of maize amended, sole planting of maize unamended, sole planting of lima beans amended and sole planting of lima beans unamended. Others were; 75:25 maize-lima beans amended, 75:25 maize-lima beans unamended, 50:50 maize-lima beans amended, 50:50 maize-lima beans unamended, 25:75 maize-lima beans amended and 25:75 maize-lima beans unamended. Wood ash was applied two weeks after planting at the rate of 2.4 kg (4 tons per hectare) to each plot. The combined yield advantage in terms of land equivalent ratio (LER) indices was greatest (1.95) in the case of 3 rows of maize and 1row of lima beans intercropping arrangements. Competition indices (CR) for all crops in all intercropping arrangements were more than 0.1 indicating that both crops were equally competitive.  However, crop aggressivity (A) showed that maize was more dominant than lima beans due to plant population. Costs and returns analysis revealed that maize and lima beans intercropping at all proportions were more profitable than their corresponding monocrops.

Introduction. Ecuador occupies the fourth place in cocoa exports with 293,487 tons per year, produced on 559,617 hectares. However, its yield per hectare is low mainly due to the presence of pathogens that affect the pods. Objective. To evaluates different methods of control of pathogens of the Theobroma cacao cv ‘CCN-51’ pod. Materials and methods. The work was carried out in Luz de America, Santo Domingo de los Tsachilas, Ecuador, between 2016 and 2017. The treatments were the result of the combination of cultural practices + two fungicides (Chlorothalonil and Pyraclostrobin) + one biofungicide Serenade® (Bacillus subtilis QST713), with and without fertilizers. In total, 16 treatments were evaluated with 3 replicates or blocks, installed in a commercial cocoa plantation cv ‘CCN-51’ and under a Randomized Complete Block Design (RCBD). Results. The use of fungicides (chemical and biological), decreased the incidence of moniliasis (Moniliophthora roreri), black pod rot (Phytophthora spp.), and cherelle wilt; but the application of fertilizers did not increase the effectiveness of these products. Treatment with only cultural practices did not decrease the final incidence of moniliasis, nor of brown rot, in contrast, the final incidence of cherelle wilt increased. The number of pods and the yield were not directly related and the highest yield of fermented and dry cocoa, corresponded to T9 [Cultural labors + Serenade® (0.2 kg ha-1) (every 15 days) + Fertilizer (0.3 kg ha-1) + Fertilizer (1 kg plant-1)], a treatment that also had the highest net income per hectare. Conclusion. Chemical and biological control can manage cocoa pods pathogens. The integration of both control methods allowed the cocoa producer to obtain greater income.

Field experiments were conducted from July to October, during 2012 and 2013 cropping seasons, at the Research Farm, University of Agriculture, Makurdi, Nigeria, to evaluate the effects of intra-row spacing of sesame and frequency of weeding on yields of maize-sesame intercrop. The trial was a 3 x 3 factorial experiment fitted in a randomized complete block design with four replications. Nine of the treatments consisted of intercropped maize with sesame sown at the intra-row spacing of 10 cm, 15 cm and 20 cm, and at the varied weeding frequencies: maize-sesame intercrop sown on plots weeded once (1x) at 3 weeks after planting (WAP); maize-sesame intercrop sown on plots weeded twice (2x) at 3 and 6 WAP; maize-sesame intercrop sown on plots not weeded (NW). Sole sesame and sole maize respectively sown at their recommended intra-row spacing of 10 cm and 30 cm and at their recommended frequency of weeding (2x at 3 and 6 WAP) constituted the tenth and eleventh treatments, which also served as control plots. The results obtained showed that in a maize-sesame intercrop, increasing intra-row spacing of sesame up to 20 cm, on plots weeded 2x at 3 and 6 WAP, significantly (P≤0.05) produced the highest intercrop yields of maize and sesame. This level of treatment not only recorded the lowest competitive pressure, but gave the highest total intercrop yields, highest land equivalent coefficient values (1.01 and 1.13 respectively, in years 2012 and 2013), indicating the highest yield advantage, and highest land equivalent ratio (LER) values of 2.11 and 2.25 respectively recorded for years 2012 and 2013. With these LER values, 52.6 % and 55.6 % of land were respectively saved in years 2012 and 2013, which could be used for other agricultural purposes. The implication of study showed that, to maximize intercrop yields of maize and sesame in a maize-sesame intercrop, the appropriate intra-row spacing for sesame is 20 cm, while the optimal frequency of weeding is 2x at 3 and 6 WAP. This should therefore, be recommended for Makurdi location, Nigeria.

Climate change is one of the serious threats to agriculture and livestock. Climate change induced and reduced water shortage lowers production of food and fodder crops. In order to investigate the effects of deficit irrigation on forage yield of maize (Zea mays L.), cowpea (Vigna unguiculata L.), and guar (Cyamopsis tetragonoloba L.) grown as sole or intercropping of maize with cowpea and guar, the fields experiments were conducted during spring 2016 and 2017 in randomized complete block design (RCBD) with split plot arrangement. These crops were further exposed to water deficit by skipping irrigation at crop stages following maize growth scale at 15 days (V4), 30 days (V6), 45 days (V9), and 60 days (V12) after sowing along with normal irrigation. Maize intercropped with guar had maximum leaf area, plant height land equivalent ratio and monetary advantage index at normal irrigation but did not differ significantly under deficit irrigation. Thus, maize intercropped with guar was found more productive and beneficial with respect to sole under deficit irrigation. © 2021 Friends Science Publishers

<p>Field experiment was conducted during the rainy seasons of 2011 and 2012 at the Teaching and Research Farm of the Faculty of Agriculture, Nasarawa State University, Keffi-Lafia Campus to study the competitive behaviour of groundnut in Sesame-groundnut intercropping system. The experiment consisted of four rates of poultry manure (0, 3.0, 6.0 and 9 t ha<sup>-1</sup>) and two planting arrangement (single alternate row and double alternate row planting arrangement). The eight treatment combinations were laid out in a randomized complete block design with four replications. The results obtained in both the years showed that sesame when grown with groundnut under different rates of poultry manure and planting arrangement appeared to be a dominant crop as indicated by its higher values of Land equivalent ratio, competitive ratio, higher and positive values for aggressivity and area time equivalent ratio. Application of 6 t ha<sup>-1</sup> of poultry manure and double alternate row planting arrangement produced the highest values for all the competition indices measured respectively.</p>
