Agronomy is a branch of agricultural science that deals with the study of crops and the soils in which they grow. It deals with various physical and biological factors-including soil management, tillage, crop rotation, breeding, weed control and climate-related to crop production. Agronomy involves the process of selective breeding of plants in order to produce the best yield of crops under different conditions.

Cropping System: The cropping pattern used on a farm and its interaction with farm resources, other farm enterprises, and available technology which determine their make up.

Agronomical practices include all management practices required for raising crops either in isolation or in rotations. Agronomic practices involve: land preparation, application of manures, scheduling and application of irrigation, and methods of plant protection including weed management, plant population management and crop geometry. These practices are affected by the soil types, climate and socio-economic status.

OFT-FLD Programme on Ground Nut:

Groundnut is an important crop which serves as a nutritional food for all age groups. In Phek district groundnut is not a new crop, the farmers are keen to cultivate but due to lack of availability of quality seeds they seldom cultivate groundnut. However in the year 2008, KVK Phek introduced a groundnut variety (JL 24) where an OFT was conducted in the same year. The performance was good and hence in the next year an FLD programme was taken up in farmersí field in 2009 for popularization of this variety. Thr cro was sown on 7/5/09 and harvested on 20/9/09. The growth and yield parameters were recorded at an interval of 30 days. The results revealed that the plant attained an average height of 50.90 cm and pod/plant was 21.20 at maturity. The total yield was 19.20 qtl/ha. Economics calculated is below:

Average cost of cultivation (Rs/ha) = Rs. 51840.00
Average Gross return (Rs/ha) = Rs. 186200.00
Average Net return (Rs/ha) = Rs. 134360.00
B:C = 3.59

The feedback from the farmers revealed that the crop performed very well and that the incidences of pest and diseases were not seen during the crop period. The farmers use groundnut for preparing local products and also consume as roasted peanuts.
