This work aimed to evaluate the dynamics of agro-economic efficiency in combinations of vegetable cowpea and radish cultivars in strip-intercropping systems through agronomic, economic and competition indices tested by the Hsu test in a semi-arid environment. The experimental design was a completely randomised block with eight treatments and four replications. The treatments consisted of combinations of four cowpea cultivars, BRS Tumucumaque, BRS Cauamé, BRS Guariba, and BRS Itaim, with two radish cultivars, Crimson Gigante and Zapp. In each block, individual plots of these cultivars in single cultivation were planted as additional treatments to obtain the system indices. The indices of agronomic and economic efficiency and of competition evaluated were land equivalent ratio (LER), actual yield loss (AYL), land use efficiency (LUE%), score of the canonical variable (Z), gross income (GI), net income (NI), rate of return (RR), corrected monetary advantage (CMA), competitive ratio (CR) and the aggressivity of radish over cowpea (Ar) and cowpea over radish (Avc). The cowpea cultivar BRS Tumucumaque, when combined with the radish cultivar Zapp, provided the highest agro-economic efficiency of the intercropped system in a semi-arid environment. The complementarity and sustainability of the intercropping systems of cowpea and radish were observed in the results of the Hsu test applied to the indices of agro-economic efficiency and of competition. Radish was the dominant crop.

To ensure food security on sustainable basis, reducing weeds interference and boosting land use efficiency are critical. A field study was conducted at research farm of University of Agriculture Faisalabad, Pakistan, to sort out the most productive maize-gram intercropping system under semi-arid environment. Treatments included sole maize in single row (60 cm apart) (T1) and double rows (90 cm apart) (T2) strips, sole black (T3) and green gram (T4) crops, six single rows (60 cm apart) of maize with twelve double rows (20 cm) of black (T5) and green gram (T6), three double rows (90 cm apart) of maize with three sets of quadratic rows (20 cm apart) of black (T7) and green gram (T8). The experiment was executed in regular arrangement of randomized complete block design with three replications. The results revealed that T1 produced the highest grain yield (6.97 t ha−1) of maize and significantly lower weeds infestation compared to wider row spacing (T2). Among intercropping systems, T8 significantly decreased weeds density (16.33 plants m−2) and their fresh (20.93 g m−2) and dry weights (5.63 g m−2), while the maximum land use efficiency as indicated by unmatched land equivalent ratio and intercropping advantage were recorded by T7 and T8. Interestingly, green gram in intercropping recorded over 58% higher productivity than black gram. We conclude that maize-green gram intercropping hold potential to impart sustainability to maize production by reducing weeds infestation (431% lower than sole maize) and could be a viable option for smallholder farmers in semi-arid environment.

Beetroot (Beta vulgaris L.) is a tuberous vegetable that is under experimentation in the vegetable production system in Rio Grande do Norte state (Brazil). It is quite demanding, in nutritional terms. One of the alternatives to meet this need is green manuring using spontaneous species of the Caatinga biome. The aim of the present work was to optimize the agro-biological performance and economic profitability of the beetroot 'Early Wonder', fertilized with different doses of hairy woodrose (Merremia aegyptia (L.) Urb.) in this semi-arid environment. Hairy woodrose is a spontaneous species of the Caatinga biome that is widely distributed, being found in forests, fences, forest clearings and fields, growing in soils of different textures, producing biomass with a high content of macronutrients. This material was collected from spontaneous vegetation, native to the region, and used as green manure.The experimental design was a randomized complete block, with four treatments and five replicates. The treatments consisted of four amounts of hairy woodrose biomass incorporated into the soil (10, 25, 40 and 55 t ha-1 of dry matter). The following agronomic characteristics were evaluated in each beetroot treatment: plant height, fresh mass of shoots, number of leaves per plant, dry mass of shoots and dry mass of roots, total and commercial root productivity, and root productivity classified into scrap and extra roots, extra A roots, extra AA and great roots. Apart from these characteristics, the following economic indicators were also determined for each treatment: gross income, net income, rate of return and profit margin. The maximum agro-biological efficiency of beet root productivity (22.68 t ha-1) was obtained from 44.92 t ha-1 of hairy woodrose biomass added to the soil. The maximum economic efficiency of the yield of beet roots was achieved as a net income of AU$2,491.00 (R$6,406.36) ha-1, provided by the production of 22.04 t ha-1 of commercial roots, using 37.03 t ha-1 of hairy woodrose biomass incorporated into the soil. The use of hairy woodrose as green manure presents agro-economic feasibility in beet cultivation in this semi-arid environment.

The triumph of the crops association with vegetables in semi-arid environment depends on crop types grown and adequate manipulation of treatment-factors tested such as fertilization, plant population, among others. Thus, this investigation aimed to valuate the bio-economic return of beet-rocket strip-intercropping in diverse balanced quantities of hairy woodrose (M. aegyptia) and roostertree (C. procera) biomass (20, 35, 50 and 65 t ha-1 on base dry) and in different rocket plant population (40, 60, 80 and 100% of that recommended population in monocropping - RPM), associated with the beet population of 100% of the RPM, in two years of cultivation. The bio-economic indices: land equivalent ratio (LER), intercropping advantage (IA), actual yield loss (AYL), productive efficiency index (PEI), canonical variable score (Z), gross return (GR) and net return (NR), rate of return (RR) and profit margin (PM) were assessed. The greatest bio-economic returns of beet-rocket strip-intercropping were of: 1.87; 7.44; 1.90; 0.98; 2.52; 85,827.79 and 65,425.01 R$ ha-1; 4.24 R$ for each real invested, and 77.02%, respectively, for LER, IA, AYL, PEI, Z, GR, NR, RR and PM in the biomass quantity of 65 t ha-1 of hairy woodrose and roostertree, in the rocket population of 100% of the RPM (a million plants ha-1). The hairy woodrose and roostertree biomass use from Caatinga biome proved to be a viable technology for growers who practice the cultivation of beet-rocket strip-intercropping in semi-arid environment.

The alley-cropping systems (ACSs), which integrate parallel tree strips at varying distances on an agricultural field can result, complementarity of resource use, in an increased land-use efficiency. Practitioners’ concerns have been directed towards the productivity of such systems given a reduced area covered by agricultural crops. The land equivalent ratio (LER) serves as a valuable productivity indicator of yield performance and land-use efficiency in ACSs, as it compares the yields achieved in monocultures to those from ACSs. Consequently, the objective of this combined experimental and simulation study was to assess the tree- and crop-yields and to derive the LER and gross energy yield for two temperate ACSs in Germany under different design scenarios, i.e., tree arrangements (lee- or wind-ward) and ratios of tree area to crop area. Both LER and gross energy yields resulted in a convex curve where the maximum values were achieved when either the tree or crop component was dominant (>75% of the land area) and minimum when these components shared similar proportions of land area. The implications of several design scenarios have been discussed in order to improve the decision-making, optimization, and adaptation of the design of ACSs with respect to site-specific characteristics.

The implementation of conservation agriculture (CA) remains crucial for facing interannual variability in climatic conditions that impact durum wheat production and food security. The current work was conducted to assess the effects of the tillage practice, previous crop, and nitrogen (N) fertilization rate on the agronomic and economic performances of rainfed durum wheat in a semi-arid environment in Tunisia. Tillage practices included no-tillage (NT) and conventional tillage (CT). Preceding crops were either a common vetch or a bread wheat. The N rates applied were: 0, 75, 100, 120, and 140 kg N ha−1. Our results show that, based on a 2-year experiment, tillage practices are not affecting grain yield, grain N, and gross margins. However, the N-use efficiency of durum wheat was significantly higher when wheat was grown using NT. Grain yield and N content in grain were 340 kg ha−1 and 0.34%; much higher after vetch than after bread wheat. For both tillage practices, the merit of 75 kg N ha−1 is paramount to maximize yield through a more efficient use of available N. Our results highlight the importance of no-tillage-based CA combined with rotation, including vetch, on enhanced yields, N-use efficiency, and gross margins. These findings provide the evidence of the positive impact of CA for rainfed durum wheat under semi-arid Mediterranean conditions.

The land use efficiency and weed suppression through intercropping plays a pivotal role. A field experiment was carried out on finger millet (Eleusine indica L. Gaertn) –horsegram (Macrotyloma uniflorum (Lam.) Verdc.) mono- and intercropping with various weeding (0, 1, or 2 hand-weeding operations) and row spacing (20 and 30 cm) treatments in the Bastar plateau region of India over consecutive five Kharif seasons (2010/2014). The experimental design was a randomized complete block with eighteen treatments replicated thrice. Five percent significant differences were observed in yield and its economics with and without weeding treatments. Horsegram yield was significantly reduced by Finger millet when intercropped. However, total productivity and land use efficiency were higher under the intercropping system as compared to monocrops of either species. There was a significant reduction in weed density and biomass for the intercropping system over both monocrops. Finger millet facilitated an increase in nodule number and dry weight in horsegram under intercropping over monocrops, moreover, root length of horsegram was greater when intercropped. These findings suggest that intercropping Finger millet and horsegram increase total productivity per unit area improve land use efficiency and suppress weeds. Focussing the experimental findings, Finger millet–horsegram (30 cm) with two weedings may be recommended for yield advantage, higher net income, more efficient utilization of resources, and weed suppression as a biological control in western plateau region of India.
