Mungbean [Vigna radiata (L.) Wilczek] cultivars (Pusa Baisakhi, PS 16 and P 105) were grown in field at atmospheric (360 ± 10 ppm, AC) and elevated CO2 (650 ± 50 ppm, EC) concentrations inside open top chambers for entire period of growth and development till maturity. Leaf net photosynthesis rate (PN) of AC and EC grown plants when compared at same CO2 concentration showed no significant down‐regulation of PN in EC plants. In cv. P 105, even up‐regulation of PN was observed in EC plants. Mungbean cultivars accumulated assimilates in the leaves during the day mostly in the form of starch. Nodule number and weight were also higher in EC plants. The positive effect of elevated CO2 on PN, dry‐matter production and seed yield was better expressed in cv. P 105 having greater podding ability.

“…Higher nitrogenase activity is also observed to be associated with higher photosynthesis rate. Ghildiyal et al (2001) and Pandurangan et al (2006) concluded that the leaf starch accumulating crops, such as mungbean and sunflower, can take advantage of higher level of substrate (elevated C02) in future as compared to leaf sugar accumulating crops like rice and wheat.…”

With these considerations, authors have tried to incorporate chapters on production and productivity scenario, canopy and root development, biological nitrogen fixation, physiology of growth and yield components, light and water-use efficiency, physiological aspects of pulse-cereal intercropping and nutritional qualities concerned with all major and minor pulses, viz. chickpea, pigeonpea, MULLaRP , and arid legumes (cowpea, moth bean, guar, winged bean), grown in different agro-ecological regions of India. A brief botany, origin and economic uses have also been covered. Chapters on ideal plant type as well as molecular basis to face challenges in pulse production are also incorporated. In the light of global climate change, a chapter on effect of greenhouse gases and global warming in pulses has been specifically included in this book. The book will fulfill the growing needs of all students and researchers of agricultural sciences in general, and of crop physiology in particular, concerned with pulses in Indian context.

Wheat (Triticum aestivum L. cv. HD 2329 and DL 1266-5) and sunflower (Helianthus annuus L. cv. MSFH 17 and MRSF 1754) plants were grown in field under atmospheric (360±10 cm 3 m −3 , AC) and elevated (650±50 cm 3 m −3 , EC) CO 2 concentrations in open top chambers for entire period of growth and development till maturity. Net photosynthetic rate (P N ) of wheat cvs. when compared at the same internal CO 2 concentration (C i ), by generating P N /C i curves, showed lower P N in EC plants than in AC ones. EC-grown wheat cultivars also showed a lesser response to irradiance than AC plants. In sunflower cultivars, P N /C i curves and irradiance response curves were not significantly different in AC and EC plants. CO 2 and irradiance responses of photosynthesis, therefore, further revealed a down-regulation of P N in wheat but not so in sunflower under long-term CO 2 enrichment. Wheat cvs. accumulated in leaves mostly sugars, whereas sunflower accumulated mainly starch. This further strengthened the view that accumulation of excess assimilates in the leaves under EC as starch is not inhibitory to P N .
