This paper presents an expert system for Paddy production management. This expert system gives advice to Paddy growers in Egypt to improve Paddy productivity. The system contains two main parts namely: strategic part and tactic part. The strategic part gives a strategic advice (i.e. list of agricultural operations) before cultivating Paddy crop. The strategic part contains four sub-systems name...

Cole crops (Brassica vegetables) can pose a significant risk for N losses during the post-harvest period due to substantial amounts of readily mineralizable N in crop residues. Amending the soil with organic C has the potential to immobilize N and thereby reduce the risk for N losses. Four field trials were conducted to determine the effects of organic C amendments (OCA) on N dynamics and sprin...

The history of remote sensing and development of different sensors for environmental and natural resources mapping and data acquisition is reviewed and reported. Application examples in urban studies, hydrological modeling such as land-cover and floodplain mapping, fractional vegetation cover and impervious surface area mapping, surface energy flux and micro-topography correlation studies is di...

Social interactions among multiple user groups of tank irrigation systems were studied to propose policies for sustainable management of tanks. Crop growers are the major competitors for water besides encroachers, fish and duck farmers. Existence of week property rights remained as the reason for the competition among users that subsequently led to conflicts. Conflicts aroused among user groups...

• Canola is one of the most profitable crops available to grain growers in southern and western Australia and rotations have been adapted to accommodate it. • Canola provides large yield benefits to subsequent cereal crops by providing an effective disease break. • Canola was often grown as the first crop after pasture but now canola is often used more intensively in rotations, posing problems ...

Blackleg disease of canola in western Canada has been effectively managed for the past 20 years through a combination of resistant varieties, adequate crop rotation intervals and good agronomics. Increased canola production in western Canada, in large measure through more frequent cropping in the rotation, has increased the risk that resistance to blackleg in current varieties may be defeated. ...

Effluent from a swine (Sus scrofa domesticus) lagoon is often applied repeatedly to nearby fields because of logistical constraints and costs of transportation. To minimize accumulation of soil nutrients and sustain use of spray field, best management practices must maximize the rates of removal of manure nutrients. Research determined summer hay and nutrient yields of bermudagrass [Cynodon dac...

Stale seedbeds are used by organic growers to reduce weed populations prior to crop planting. Ryemulches, derived from mechanically killed (rolled and crimped) winter rye cover crops, can serve the same purpose for spring-planted organic crops. Both methods can also be employed by conventional growers who face looming problems with herbicide resistant weeds. The objective of this research was t...

Onattukara sandy loam tract an important agro ecological zone spread over the Karunagapally taluk of Kollam and Karthikapally and Mavelikara taluks of Alappuzha districts of Kerala. The soils are highly permeable, acidic in reaction and are extremely deficient in all the major plant nutrients. Sesamum is mainly grown in Kerala as a sole crop in the summer rice fallows of Onattukara tract. The c...
