Use of information and communication technologies can improve the agricultural and rural development. Client server architecture in conjunction with the mobile applications on smart-phones can be useful for delivery of the precise agricultural information to the farmers. Geographical data of mobile phones can further localize the required information needs of the farmers. In this paper, an approach have been suggested for hybrid architecture based on mobile and web technology using the location. The inference of the decision to disseminate information can be made dynamic using an improved rule promotion technique.

The field experiment was conducted during rabi 2013-14 and 2014-15 at Agricultural Research Station, Sumerpur, Pali (Rajasthan), India to find out suitable organic nutrient management practices for higher productivity and economics of wheat in Luni basin region of Rajasthan. The experiment was laid out in RBD with seven treatments. The results in terms of growth and yield attributes, grain yield and economics of wheat under different treatments were significantly different than control. Pooled data of two years' experimentation revealed that the maximum plant height (85.83 cm), number of tillers per meter row length (91.00), number of seed per ear head (55.18), ear head length (9.60 cm), test weight (37.17 g) and grain yield (39.14 q ha -1 ) were recorded with application of FYM @ 10 t ha -1 +Vermicompost @ 1.25 t ha -1 followed by treatment FYM @ 5 t ha -1 +Neem green leaves @ 2 t ha -1 +Vermicompost @ 1.25 t ha -1 . Net return was recorded significantly highest with FYM @ 10 t ha -1 + Vermicompost @ 1.25 t ha -1 whereas B:C ratio (2.43) was highest with FYM @ 5 t ha -1 +Neem green leaves @ 2 t ha -1 +Vermicompost @ 1.25 t ha -1 . Application of FYM @ 5 t ha -1 +Neem green leaves @ 2 t ha -1 +Vermicompost @ 1.25 t ha -1 led to increase grain yield by 94.84% significantly over control (19.0 q ha -1 ). Hence, the finding suggested that the integration of FYM @ 5 t ha -1 +Neem green leaves @ 2 t ha -1 +Vermicompost @ 1.25 t ha -1 increased yields of organic wheat in semi arid regions.
