“…The variation in land equivalent ratio might be due to variation in seed yield in sole crop as well as in intercrops. Such findings were also reported by Bhatnagar and Pal (2014), Choudhary et al (2014) and Shaker-Koohi et al (2014).…”

A field experiment was conducted during kharif season of 2014 at Research Farm, RVSKVV, College of Agriculture; Gwalior (M.P.). The experiment was laid out in randomized block design (RBD) replicated thrice with 16 treatments. The sole crops namely clusterbean, cowpea, greengram, blackgram, mothbean and soybean gave significantly higher values of all growth attributes viz., plant height and number of branches/plant; yield attributes viz., number of pods/plant, number of seeds/pod and seed index and yield viz.; seed and stover (kg/ha) over various clusterbean based intercropping systems. However, the significantly higher clusterbean equivalent seed and stover yield (2775 and 5694 kg/ha, respectively), gross and net monetary returns ('141593 and '121719/ha; respectively) and benefit : cost ratio (7.12) were recorded under Clusterbean + Cowpea (2:2).

“…Subsequently, predefined or 'blanket' recommendations might not be useful in the local context. Additionally, the choice of legume species to be intercropped with maize needs to be carefully considered because the agronomic performance of the cropping system varies with the types of legume species (Polthanee & Trelo-ges, 2003;Choudhary et al, 2014).…”

‘To Adopt or not to Adopt?’ Legume Adoption in Maize‐Based Systems of Northern Thailand: Constraints and Potentials

A considerable growth in the maize (Zea mays L.) sector in Southeast Asia has resulted in a rapid expansion and intensification of maize monoculture on sloping uplands. This practice entailed the heavy use of fertilisers, leading to environmental degradation and farmers' indebtedness. Intercropping of legumes with maize could complement or replace fertiliser inputs; however legume adoption by smallholder maize farmers remains low. This study investigates the constraints and potentials to integrate legumes in maize‐based cropping systems in such environments. A comparative study between maize monocropping and maize/legume relay cropping was carried out in two villages of Thailand, using surveys, participatory rural appraisal (PRA) tools and interviews. The results demonstrated that both cropping systems were equally profitable, although the maize yield in maize/legume relay cropping was lower than that in monocropping. Low selling price was the most cited reason by the non‐adopters for not introducing legumes. Selling price of legume grains, ease of harvesting, marketability and ease of growing were the four main criteria that determined the adopters' choice of legume species. Among the cultivated legumes, ricebean (Vigna umbellata L.) best fulfilled the criteria for the choice of legume species. Establishing maize/legume relay cropping as an alternative to maize monocropping under rainfed conditions can decrease risks, due to reduced expenses for farm inputs and similar economic returns. This study generated useful information for agricultural policy makers and development practitioners in identifying the barriers and facilitating factors that influence farmers' decision to adopt legumes and the conditions that shape the farmers' decision‐making environment.

“…The experimental site received an average annual rainfall of 2400 mm and the monsoon months (June to September) contributed more than 77% of it ( Figure 1). The soil of the experimental site was silty loam in texture (sand: 33.4%, silt: 51.2% and clay: 15.4%), acidic in reaction (pH 5.3), and high in organic carbon (Walkley and Black, 13.2 g kg −1 ), low in available nitrogen (alkaline permanganate N, 193.8 kg ha −1 ), low in available phosphorus (Bray P, 8.4 kg ha −1 ) and available K (neutral normal ammonium acetate K, 210.5 kg ha −1 ) as earlier described by Choudhary et al (2014). Soils were moderate in water retention capacity (18-21% at 0.3 bars and 9-11% at 15 bars) and moderate in compaction level (bulk density: 1.42 mg m −3 )…”

“…The decrease in available space and light in intercrops due to more crop canopy cover resulted in reduction in weed density and biomass, thus, registered higher WSE. In the uplands of the EHR, due to high rainfall, richness in biodiversity and higher soil organic carbon (Choudhury et al , 2013), vigorous weed growth and its infestation is one of the major causes of low productivity (<1.5 t ha −1 ) of the predominantly maize-based, rainfed agriculture (Choudhary et al , 2014). There are reports that due to the heavy weed infestation, the yield loss of rainfed, maize-based system ranges from 26 to 70.5% and, even in extreme cases, partial to complete crop failure is encountered (Singh et al , 2009).…”

SUMMARYThe effects of sole and intercropping of rainfed maize (Zea mays L.) were evaluated with soybean (Glycine max L.) and groundnut (Arachis hypogea L.) on crop yield, weed smothering efficiency (WSE) and nutrient (NPK) balance at Eastern Himalayan Region (EHR), India. Grain yield of maize was highest (3886 to 4110 kg ha−1) in the solitary system followed by maize-soybean intercrops at 1:2 rows. However, system productivity as well as production efficiency was higher by 47.3-63.3% and 39.5-58.4%, respectively in intercropping with groundnut at 1:5 rows compared to solitary maize. WSE was relatively higher to solitary soybean and was comparable to maize-groundnut intercropping at 1:5 row proportions. Similarly, NPK uptake was higher in intercropping of maize-soybean systems at 1:5 row proportions. Inclusion of legumes as intercrops in predominantly solitary rainfed maize may improve the system productivity while sustaining the nutrient availability in the vast uplands of the EHR and other similar rainfed hilly ecosystems.
