Dryland farming is a special case of rainfed agriculture practiced in arid and semiarid regions in which annual precipitation is about 20–35% of potential evapotranspiration. Conditions of moderate-to-severe moisture stress occur during a substantial part of the year, greatly limiting yield potential, and in which farming emphasizes water.

Ratna Reddy, Geoffrey J. Syme, in Integrated Assessment of Scale Impacts of Watershed Intervention, Background. Rainfed agriculture accounts for more than 75% of the cropped area in the world. One-third of the developing world’s population lives in the less-favored rainfed regions [1].In India, rainfed agriculture accounts for 60% of the cropped area, and is the food basket for.

Dry Land Farming. Indian agriculture is traditionally a system of Rainfed agriculture. Out of million hectares of net cropped area, about 72% is Rainfed production about 45% of food grains and 75 – 80% of pulses and oil – seeds and a number of important industrial crops.

Suggested Book. Difference b/w Dryland farming and rainfed farming: Dryland farming Dry land farming is cultivation of crops in regions with annual rainfall of more than mm. Inspite of prolonged dry spells, crop failure is relatively less frequent.

The dynamics of dryland farming are different and harsh than irrigated farming. So the problems of dryland agriculture are also unique. Water is the chief requirement for cropping.

The crops in dryland or arid lands have to face the challenge of shortage of water more frequently. Rainfall is the sole option for them to get water. Dry land agriculture 1. Dryland agriculture Growing of crops entirely under rainfed condition is known as dryland agriculture.

Depending on the amount of rainfall received, dryland agriculture can divided into three categories: 1. The chapters of the book have been selected and arranged in such a manner as to lead the students through the entire gamut of rainfed agriculture supported by suitable examples and diagrams.

Dryland farming constitutes about 72 per cent of the total cropped area of million hectares (Mha) in India contributing to about 42 per cent of total food production (Reddy, ).

Almost entire coarse grains and about 75 per cent of oil. Dryland farming: In dryland Pulses, oilseeds, coarse grain crops and cotton are mainly cultivated. Some technologies are used to increase crop production in drylands and these technologies are also increases the agricultural productivity.

High production of pulses and oilseeds leads to increase in the economic status of the farmers. Rainfed. Dryland agriculture refers to cultivation of crops entirely under natural rainfall without irrigation. It is a form of subsistence farming in the regions where deficit of the soil moisture retards the growth of water consuming crops like rice (Oryza sativa), sugarcane etc.

Dryland areas are characterized by low and erratic rainfall and no assured irrigation facilities. Author by: Suhas P.

Rainfed agriculture is used to describe farming practices that rely solely on precipitation for water. Although dryland farming is a part of rainfed farming, it occurs primarily in semiarid areas. Today, however, the problem is becoming much more serious.

Over 20 per cent of the world's population lives in dryland areas, and unless action is taken drylands will increase dramatically. This book focuses on the people who live in the drylands, their use of land resources and the economic returns from their decisions.

A new book that challenges those who see India's rainfed agriculture and livestock systems as inherently vulnerable to food insecurity and poverty, will be debated at a panel event on Friday, 21 August at 3pm at Jawaharlal Nehru University (JNU).

In India, nearly million ha of land is under rainfed cultivation and therefore, rainfed agriculture will continue to play an important role in the Indian economy. The disappointing results of conventional cropping systems in advancing the productivity of small farms were the driving force in the development of farming systems research.The book fills the need for an up-to-date comprehensive text on the Dry land Agriculture under varying situations for the students at under graduate and post graduate levels.
