“…Land equivalent ratio (LER) was computed by using the formula described by Willey et al (1980) When the value of LER is greater than 1, the intercropping favours the growth and yield of the species where as when LER is lower than 1, the intercropping negatively affects the growth and yield of crops grown in mixtures (Caballero et al 1995).…”

A field experiment was conducted during kharif 2011 and 2012 at Sartangal to study the effect of intercropping and nutrient management on productivity and profitability of cultivating maize under sub-alpine conditions of Jammu. The inter-cropping systems were sole maize, sole rajmash, maize + rajmash in a 1:1 row (1 rows of maize alternating with 1 row of rajmash) and maize + rajmash in 2:1 row (2 rows of maize alternating with 1 row of rajmash). The nutrient management treatments were, T 1 =control (no fertility), T 2 = 100% NPK (RDF, recommended dose of fertilizers), T 3 = 75% RDF + 25% N through farmyard manure (FYM) and T 4 =50% RDF + 50% N (FYM). Among cropping system maize + rajmash (1:1) produced highest maize grain equivalent yield (MEY, 7772 kg ha -1 ), net returns (INR 52190 ha -1 ), B:C ratio (1.81), land equivalent ratio (LER, 1.40) and area time equivalent ratio (ATER, 1.38). Whereas among nutrient management techniques, 75% RDF + 25% N (FYM) produced highest MEY (7681 kg ha -1 ), net returns (INR 52585 ha -1 ) and B:C ratio of 1.88 with highest LER (1.36) and ATER (1.33).

“…Analysis of long-term experiments indicated that increasing crop rotation intensity from single crop (corn) to double crop (corn-soybean) enhanced carbon sequestration by 20 g cm −2 year −1 in humid continental climate at Wooster of Ohio, USA (West and Post 2002). In India, intercropping is an ancient agricultural practice, particularly intercropping of sorghum and pigeon pea (Willy 1983;Wang et al 2010). Latin American farmers grow their 70-90% of the beans with maize, potatoes and other crops (Francis 1986).…”

Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population and natural resource degradation including soil degradation and biodiversity loss. Climate change is among the greatest threats to agricultural systems. Green Revolution though multiplied agricultural production several folds but at the huge environmental cost including climate change. It jeopardized the ecological integrity of agroecosystems by intensive use of fossil fuels, natural resources, agrochemicals and machinery. Moreover, it threatened the age-old traditional agricultural practices. Agriculture is one of the largest sectors that sustain livelihood to maximum number of people and contribute to climate change. Therefore, a climate-smart approach to sustainable food production is the need of hour. Traditional agriculture is getting increased attention worldwide in context of sustainable food production in changing climate. The present article advocates traditional agriculture as a climate-smart approach for the sustainable food production and also deliberates the correlation between climate change and agriculture.
