“…Em relação à produção de fitomassa seca, também foram constatados efeitos significativos das épocas de semeadura, dos adubos verdes e da interação entre eles (Tabela 2), atribuídos à ação do ambiente sobre essa variável. Wildner & Dadalto (1991), Chauhan et al (1993), Nam et al (1993) e Calegari (1995 reportaram o mesmo efeito, tanto para C. juncea, como para guandu. Balakrishnan & Natarajaratnam (1989, 1990 e Rana & Malhotra (1992) confirmaram a interferên-cia da época de semeadura sobre a matéria seca acumulada pelo guandu, com acentuadas reduções desse parâmetro com o deslocamento da época adequada de plantio.…”

RESUMO -Com o objetivo de avaliar o crescimento e desenvolvimento de leguminosas utilizadas como adubos verdes, instalaram-se três ensaios, em três épocas de semeadura e dois espaçamentos na região dos Cerrados, durante o ano agrícola de 1991/1992, na área experimental da Embrapa-Centro Nacional de Pesquisa do Solo (CNPS), em Senador Canedo, GO. As espécies avaliadas foram Crotalaria juncea L., mucuna-preta (Mucuna aterrima (Piper & Tracy) Merr.), guandu cv. Kaki (Cajanus cajan (L.) Millsp.) e Crotalaria ochroleuca G. Don. O delineamento experimental utilizado, dentro de cada época, foi o de blocos ao acaso com parcelas subdivididas, com três repetições. Os resultados indicaram que C. juncea e C. cajan apresentaram as maiores produções de fitomassa seca. O atraso da semeadura, em relação ao início da estação chuvosa, reduziu os rendimentos de fitomassas verde e seca produzidos pelas leguminosas, exceto pela mucuna-preta. Os espaçamentos de 0,5 m e 0,4 m não influenciaram o período para o florescimento e as produções de fitomassas verde e seca.Termos para indexação: Mucuna aterrima, Crotalaria juncea, Crotalaria ochroleuca, Cajanus cajan, adubação verde. EVALUATION OF GREEN MANURES IN DIFFERENT SOWING DATES AND ROW-SPACINGS IN THE CERRADOS REGIONABSTRACT -In 1991/1992 growing season, three field experiments were carried out to evaluate the growth and development of sunn (Crotalaria juncea), Crotalaria ochroleuca, black velvet bean (Mucuna aterrima), pigeon pea cv. Kaki (Cajanus cajan) as green manures at three sowing dates and two row spacings at Embrapa-Centro Nacional de Pesquisa de Solos (CNPS), Senador Canedo, GO, Brazil. The experimental design used was a complete randomized block with split-plot and three replicates. Highest yields of dry matter were obtained with C. juncea and C. cajan. The delay in sowing dates to the beginning of the rainy season, reduced yield of fresh and dry matter of all legume species, except black velvet bean. Row-spacings of 0,5 and 0,4 cm did not influence the time for flowering and the yield of fresh and dry matter. que poderá causar à produção da cultura comercial. Seu uso pode ser viabilizado com a semeadura no final da estação chuvosa, em sucessão à cultura (Pereira et al., 1992). Esse plantio pode ser realizado, ainda, aproveitando a ocorrência de veranicos, quando o preparo do solo e a semeadura são passíveis de serem realizados, e no início do período das chuvas, à medida que o plantio da cultura principal possa ser efetuado a posteriori. Atualmente, entre as diversas leguminosas promissoras para adubação verde na região dos Cerrados, destacam-se: mucuna-preta (Mucuna aterrima), guandu (Cajanus cajan), crotalárias (Crotalaria juncea, Crotalaria ochroleuca,

“…These lines (MN 1, MN 5, and MN 8) flowered in 45-50 days and matured in 70-85 days at ICRISAT, Patancheru (17 N latitude), and have served as an excellent source for earliness in many breeding programs globally. ESD lines are also grown as a catch-crop (Chauhan et al 1993, Nam et al 1993, and in rice fallows in the short-rainy season in Sri Lanka (Chauhan et al 1999), India, and the Philippines. These lines are used for diversifying cereal-based crop rotations of rice-wheat cropping systems, particularly in the Indo-Gangetic plains.…”

Biodiversity in Agriculture

More than six billion people of this planet are dependent on nurturing and harnessing agro-ecological biodiversity for food and nutritional security. Human life and civilizations have been influenced not only by cultivated taxa, but also by wild germplasm. The origin and fast-track evolution of agricultural crops aided by domestication have attracted considerable attention from evolutionary biologists, plant explorers, archaeobotanists, geneticists, and plant breeders worldwide in crops such as rice, wheat, and maize. However, legumes (barring soybean) have remained relatively neglected by the researchers. Globally, pigeonpea is grown on an area of 4.64 million hectares (Mha) annually with production of 3.43 million tonnes, yielding 740 kg ha À1 (FAO 2008). In the past three decades India has contributed to more than 70% of global area and production of pigeonpea. India (cultivating 3.53 Mha), Myanmar (570,000 ha), China (150,000 ha), and Nepal (20,988 ha) are the most important Asian countries for pigeonpea production (Table 16.1). In Africa, Kenya (190,000 ha), Malawi (123,000 ha), Uganda (87,000 ha), and Tanzania (67,500 ha) are the leaders. Pigeonpea is a versatile food legume. A dried decorticated split pea (dhal) is consumed as protein source in many Asian and African countries. Green seeds and pods are also consumed as a vegetable in parts of India and Africa. The seed husk and pod wall form quality animal feed. The dried stems of pigeonpea are a good source of fuel wood (the calorific value is about half that of coal (Panikkar 1950)), thatch, and material for basket making. Pigeonpea helps in release of soilbound phosphorus (Ae et al. 1990). Like other legumes, pigeonpea fixes about 40 kg ha À1 nitrogen per season (Kumar Rao et al. 1983). There are also reports of up to 280 kg ha À1 of nitrogen fixation (Red de Grupos de Agricultura de Cobertura 2002). Pigeonpea has also been used as a green manure crop, a cover crop, and food for silkworms (Red de Grupos de Agricultura de Cobertura 2002) and as a host for the lac insect (Kerria lacca). The deep root system of pigeonpea breaks the soil hard-pan and helps in nutrient recycling from the deeper layers of soil. Long-and medium-duration pigeonpea varieties have also been successfully used for mountain slope stabilization in southern China and Northern India.

“…Development of extra-short duration of pigeonpea genotypes has enabled them to escape the terminal drought, which short and medium duration types may experience (Nam et al, 1993). Extra-short duration pigeonpea genotypes may experience intermittent stress, as they are dependent on current rainfall, while medium and long duration types may experience intermittent as well as terminal drought (Chauhan et al, 1993). Genotypic differences in drought tolerance in pigeonpea have been reported (Lopez, et al, 1996).…”

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.
