Drought is one of the most serious problems arising for human societies and ecosystems from climate variability. Although its impact does not come through sudden events, such as flood and storms, drought is the world’s costliest natural disaster, causing an average $6– $8 billion in global damages annually and collectively affecting more people than any other form of natural disaster (Wilhite, 2000). The National Commission on Agriculture (MOA, 1976) identified 74 drought prone districts which all are located 13 states of India and Gujarat is one of the most drought prone areas of India in which, eleven districts of the state are in arid regions including Dahod region one of most backward district; agriculture based livelihood income and experienced drought problems many times throughout the years due to delayed in rainfall. Therefore, study was carried out to determine hydrological and agriculture panoramas of drought in the Dahod district includes 7 Talukas. It was found that annual rainfall in Dahod district varies between 690 mm at Garwada to 847 mm at limkheda with the average annual rainfall of 833mm and average drought frequency in Dahod district varies between 1 in 4 years at Jalod, Limkheda 1 in 3 years, Devgarh 1in 5 years, Garbada 1 in 3 years, Dhanpur 1 in 3 years, and 1 in 3 years at Fatepura. The relative departure index (RDI) was observed for various Talukas in which, Dahod district was recorded frequent drought prone taluka and considered for taking up drought mitigation activities. The standardized precipitation index (SPI) was analysed between the year of mid 1999-2003 taluka was suffered from moderate and severe drought conditions whereas, between the years of mid 1993 to mid 1999 meteorological condition was normal.Keywords

Rotary tillage implements are now projected as important tillage machinery for better seedbed preparation; however, the ordinary rotavator being in line with the tractor center line at the rear cannot be used in orchards due to the hindrance posed by narrow space between the plants. Therefore, the concept of a modified offset rotavator was proposed, which could perform intercultural operation between the plants. The study was conducted to evaluate the performance of the modified offset rotavator in guava orchard of Horticulture Research Center, Pantnagar. It was found that the draft (negative) for the L-shaped blades increased (1203.4 to 1841.4 N) as the forward speed increased (2.0 to 3.0 km/h) with Increase in depth of cut (80 to 120 mm) for the shield kept in the lowered (down) position and fuel consumption was higher 9.93 l/h at given forward speed 3.0 km/h with 120 mm depth of cut. Soil break up (mean mass diameter) resulting from the Impact action of L-shaped blades on soil was found increased (1.05 to 1.95 mm) as the forward speed increased (2.0 to 3.0 km/h). The extent of residue incorporation was the maximum 97.30 % at forward speed 2.0 km/h with 120 mm depth of cut, whereas at higher forward speed 3.0 km/h, field performance index was observed 88.28 %. The minimum area uncovered near the girth was reported 0.143 m2 at higher girth 0.48 m while plant injury at 3.0 km/h resulted due to impact of sensing assembly with plants was found 50 % in form of scratch on the girth.Keywords

This computer application deals with energy auditing for rice-wheat cropping system. Computing different input parameters for the crop production system in terms of energy requirement (MJ/ha) can be done by using this computer application. The developed application was found to be a simple, easy and user-friendly with appropriate output units. It works efficiently and gives the desired output in terms of energy consumption (MJ/ha). The advantage of this application is to decide the inputs on the basis of energy consumption before performing actual cultivation practice using the last season data. Moreover, using this package energy budget difference and comparison of subsequent production seasons can be achieved. The computer application was developed using Visual Basic, which allows the user to calculate total energy use efficiency, specific energy and different energy ratios in a particular cropping system.Keywords
