Ebook "Tropical agroforestry" strives to provide up-to-date information on tropical agroforestry to serve as educational material in the tropical context. The authoritative textbook of Nair (1993) on agroforestry was published 18 years ago, and before the advent of tree domestication, an important agroforestry practice today. In addition, many other research activities, such as carbon sequestration and integrated pest management, have been included in the agroforestry agenda.

"Productivity of sorghum (Sorghum bicolar L.) at diverse irrigation regimes and sowing dates in semi-arid and arid environment" was conducted to determine impact of sowing dates, irrigation regimes, and cultivars on yield and growth traits during 2016 and 2017 at two locations in Pakistan. Determining optimal sowing date, optimal number of irrigation applications, and best-performing cultivars is critical to maximizing achievable sorghum yield in semiarid and arid environments.

Research on the genetic diversity and structures of endangered plant species with small population sizes is a prerequisite for developing reasonable conservation strategies. Ferula sinkiangensis K.M.Shen is a critically endangered herbaceous perennial and monocarpic medical plant growing in semiarid steppe ecosystems with a small population size within the Yili Valley in Xinjiang, China. Unfortunately, the lack of genetic information has limited our ability to initiate effective conservation strategies for the species. In this study, 14 polymorphic microsatellite primers of F.

Pomegranate (Punica granatum L.) is one of the important fruit crop of arid and semiarid regions of the world belongs to family Punicaceae. This fruit crop is often cross pollinated, genetically heterozygous and appropriate natural variation is present. Traits like reducing the size of the plant in order to increase orchard plant density, selecting self fertile genotypes to maintain a higher consistent yield over time and selecting genotypes with higher nutritional value of the fruit are important for ideotype plant in pomegranate.

Seed spices are important commercial crops of arid and semiarid regions of India and accounting major contribution for domestic and export market. In these regions water is one of the main constraint in crop production since the growing areas are deficit in annual rainfall and these crops are grown during winter season requires assured irrigation for successful production.

Water deficit stress is one of the important factors limiting chickpea production in arid and semiarid regions. Water deficit induced b Polyethylene glycol (PEG) affect physiological and biochemical changes in Chickpea. This investigation was undertaken to evaluate morpho-physiological parameters, levels of osmolytes and activities of antioxidative enzymes under PEG 6000 induced osmotic moderate and severe stress in pot. The plants were subjected to two progressive stresses: moderate (-0.4 MPa) and severe stress (-1.2 MPa).

Recently, abiotic stress like salinity, drought and temperature are the severe problems to worldwide wheat production, mostly in arid and semiarid areas. A feasible solution is breeding for salt-tolerant cultivars of wheat, while the presence of genetic variation is a prerequisite for genetic improvement. In the present investigation, an experiment was conducted to estimate the nature and magnitude of genetic diversity in improved varieties of bread wheat during Rabi, 2010-11.

clusterbean (Cymopsis tetragonoloba (L.) Taub.) An attempt has been made to evaluate the effect of abiotic constraints (drought and temperature) on the growth of rhizobia isolated from clusterbean grown in semiarid regions of Haryana with a view to screen out stress tolerant rhizobial isolates. A total of 158 rhizobial isolates have been used for screening their stress tolerating ability with contrast to environmental abiotic soil conditions commonly prevailing in semi-arid regions of Haryana. All the isolates were phenotypically and biochemically characterized.

Chickpea (Cicer arietinum L.) is one of the major rabi pulse crop and is a cheap source of protein. It has also advantages in the management of soil fertility particularly in dry lands and the semiarid tropics. Despite of low productivity of chickpea is attributed to Fusarium wilt disease which caused by obligate biotroph Fusarium oxysporum f.sp. ciceri is consider one of the major limiting factor.

India is the largest producer and consumer of the pulses in world. There is a huge shortage of pulses in the country to meet out the domestic demand especially of vegetarian population. The low production and productivity of pulses under Indian condition is mainly due to several biotic and abiotic constraints. In general, the pulses crops are more susceptible to the stresses including weeds as compare to the cereals and oilseeds. It was widely reported that yield losses due to weeds especially in the pulses are more than the loss caused either by insect-pest or diseases.
