“…It could be due to increased plant population pressure of main and intercrop together resulting in increased competition for nutrients, water, space and light which leads to decreased biomass and yield which was found maximum in exhaustive cereal crops. These results agree with the findings of Mallikarjun et al (2018) [5] and Shivakumar et al (2021) [8] .…”

In rainfed and dry regions of southern Karnataka, sole cropping is not much remunerative in the current scenario of climate change to meet the pulses requirement of growing population. Hence, the field experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, GKVK, Bengaluru during Kharif, 2021 to evaluate the most promising intercrops (sweet corn, baby corn, sorghum, vegetable soybean, field bean, quinoa and grain amaranth) in pigeonpea based cropping system and its effect on growth, yield and economics of pigeonpea where previously pigeonpea was cultivated as a sole crop. The experiment was laid out in RCBD with 15 treatments each replicated thrice. Higher pigeonpea seed and stalk yield (852 and 1678 kg ha -1 , respectively) were observed in pigeonpea + field bean (1:2) intercropping which was on par with vegetable soybean (1:2). The data revealed that higher seed yield was mainly attributed to higher plant height, leaf area, total dry matter production, no. of pods and pods weight per plant. However, planting of pigeonpea with sweet corn (1:2) as intercrop recorded higher pigeonpea equivalent yield (2724 kg ha -1 ), net returns (Rs. 2, 96,750 ha -1 ) and benefit: cost ratio (4.91) than rest of the treatments. Whereas, higher system indices like land equivalent ratio (1.43) and area time equivalent ratio (1.19) were recorded with pigeonpea + field bean (1:2) intercropping system.

“…Usually tap rooted legumes obtain deep root system when compared to fibrous rooted cereals. It has already been documented that, pigeon pea has is capable of hydraulic lift (Sekiya and Yano, 2004;Sekiya et al, 2011) and is common choice in finger millet based intercropping system of rainfed situation (Maitra et al, 2000;Padhi et al, 2010) and also with other cereals namely maize (Garland et al, 2016) nutri Cereal (Mallikarjun et al, 2018) particularly in India. A deep-rooting pigeon pea (Cajanus cajan) bioirrigates the neighboring shallow rooted finger millet (Eleusine coracana).…”

Exploring ecosystem services for environment sustainability is the trending area of research in the field of natural resource management (NRM). Water is an important entity of agro-ecosystem, dryland agriculture greatly suffers due to want of moisture. Bi-cropping is one practice where different crops are grown in proximity to realize various benefits under uncertainties of dryland agriculture. Literacy among multifarious benefits of bi-cropping over monoculture is fairly rich among the researchers as well as growers. However, bio-irrigation is one such co-benefits which address about drought alleviating strategies under bi-cropping practice. In this technique, deep rooted plants suck up water from deep moist sub-soil and deposit part of that sucked water in the upper dry soil layers due to water potential gradient, during this hydraulic lift and redistribution shallow rooted neighboring crops in close proximity gets due benefits of this lifted water in alleviating drought. This is high time to device cropping systems of water limited environment to unlock the potentiality of dryland production units. Based on the published studies Piliostigma reticulatum, Guiera senegalensis, Panicum maximum, Festuca arundinacea and Cajanus cajan were identified as potential bio-irrigator arid agro-ecosystem.
