M.Sc. (Ag) Agronomy 2nd semester
This ppt is about the distribution of wasteland and problem soils. Those lands are wastelands which are ecologically unstable,
whose topsoil has nearly been completely lost, and
which have developed toxicity in the root zones or growth of most plants, both annual crops and trees”.
Sub: Rainfed Agriculture and Watershed Management.
Topic: Drought: types, effect of water deficit on physio-morphological characteristics of the plants, Crop adaptation and mitigation to drought
Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to their leaves. Plants are able to absorb essential elements through their leaves. The absorption takes place through their stomata and also through their epidermis.

Role of watershed management in reducing soil erosion zewde azewde alemayehu
Soil is one of the most important and essential natural resources. Soils offer plants physical support, air, water, temperature moderation, nutrients, and protection from toxins. Soils provide readily available nutrients to plants and animals by converting dead organic matter into various nutrient forms.
Conservation Agriculture (CA) is a concept for resource-saving agricultural crop production system that strives to achieve acceptable profits together with high and sustained production levels while conserving the environment.
It is based on minimum tillage, crop residue retention, and crop rotations, has been proposed as an alternative system combining benefits for the farmer with advantages for the society.
Conservation Agriculture remains an important technology that improves soil processes, controls soil erosion and reduces production cost.
Global Soil Partnership’s vision - a sustainable and productive use of the soil resources of the world and sustainable agricultural production is the core message of the presentation.
It addresses the key role of soil resources for sustainable land management and sustainable development, soil a finite resource, the impact of human activity on soil, critical soil issues in relation to food security and climate change adaptation and mitigation, soil productivity, soil degradation – status and trends, current and future challenges, future food demand, population growth, water scarcity and outlooks.

Rainfed Agriculture PPT
1. Rainfed Agriculture
Introduction: Rainfed agriculture hinges the food and
livelihood security of a large number of people
worldwide (Rockstro¨m et al., 2010).
Communities in the arid and semi-arid zones of the
world are faced with food deficits almost on an annual
basis due to crop failure (Makurira, 2010).
Water scarcity is the biggest threat to food self-
sufficiency, which seems to exert even stronger
influence on rainfed agriculture in future (de Fraiture
et al., 2007; Hoff et al., 2009; Kijne et al., 2009).
The scarcity of water for food production particularly
through agricultural droughts and dry spells will be a
big challenge for water management (Savenije, 1998,
Rockström, 2003).
2. CONT…
One of the major crop production constraints in semi-arid
areas is short growing period, short term rainfall with high
runoff and moisture deficit (Madalcho. and Sido, 2015).
In such area, in-situ rainwater harvesting techniques are
very crucial. The in-situ moisture conservation methods
influenced soil water availability and subsequent
vegetative growth and yield (Sudhishri et al., 2008; Dass et
al., 2011 and Manyatsi et al., 2011).
Under such situations, alternate land use systems are
receiving greater attention in many countries to protect the
land from various types of degradation, diversifying the
farming system and increasing the soil carbon build up and
moisture (Masebo et al., 2014; Lenka et al., 2012; Singh
and Pandey, 2011; Lithourgidis et al., 2011).
3. CONT…
Water is crucial input for augmenting agricultural
production towards sustainability in rainfed agriculture
which depends to a great extent on water saving
technologies and its efficient rainwater management.
Proper mechanical and vegetative structure can help to
conserve the rainwater in-situ and provide the quite
essential moisture for crop growth.
There are several soil and water conservation measures for
reduction of runoff and soil loss, such as strip cropping,
contour and graded bunding etc. Which not only controls
the runoff more efficiently but also curtails the soil loss and
enhanced the crop yield.
Developing technologies to increase agricultural water-use
efficiency (WUE) through water harvesting and
conservation is a need and majority of the farmers have
been ignorant and unconfident of growing crops on dry
lands (Allolli, 2008).
4. CONT…
Horticulture has assumed significant importance in the crop
diversification in recent years, which has become essential to
arrest serious land degradation and enhancing the farm income.
Horticulture crops like citrus (citru sp.), guava (Psidium
guajava), Bael (Aegle marmelos) and ber (Ziziphus mauritiana)
play important role in enhancing farm income in vulnerable
rainfed areas. Hardy fruit crops have better choice in these areas.
Awasthi and Pareek (2008)
Utilization of inter-space between trees can improve soil
nutrient and biological characteristics, physical properties,
enhancing total biomass production and further improve
farmer’s income from a unit land. Agri-horti system is one of the
most important cropping systems (Singh et al., 2013).
5. CONT…
Legume crops intercropped in tropical fruit tree
production may act as important cash and trap
crops. Apart from fixing atmospheric N2,
recycling nutrients and improving soil nutrient
availability, they also help reducing erosion risks
and organic matter losses (Lehmann et al., 2000).
Conjunction vegetables with Horticultural trees
enhance the soil fertility and crops productivity.
6. Main Constraints of Rainfed Agriculture
Deforestation and shifting cultivation
Soil erosion and degradation of hills
Flooding in plains
Low water quality for irrigation
Lack of water resources
Lack of sufficient transport and communication
Technology gaps in agriculture and animal husbandry
Rainfed agriculture affected by undependable and highly variable pattern
Poor socio-economic system of the farmers
7. Strategies For Development
Soil and water conservation measures
Control in shifting cultivation
Mushroom cultivation, sericulture and growing horticulture crops like pine apple,
mandarin orange pomegranate, Guava and citrus
Drainage, land grading and storage of excess water in flood prone areas
Augmenting irrigation sources and multiple cropping
Extensive live stock development
