Solar operated seed sowing and agricultural spray

A pre fertilizer cum seed drill was designed and developed by selecting the best parameters from previous model studies. The equipment consisted of a main rectangular frame, one tines which is expand according to need of different depths, and one hoppers for carrying seed in one , supporting wheels with depth control provision, one solar panel is mounted on the main frame which can be manually adjustable according to the sunlight ,a 12volt battery is attached with solar panel for use this equipment in rainy season, one tank of PVC is fitted on the frame to store the pesticide, four nozzles provided for spraying purpose. The basic objective of sowing operation is to put the seed and fertilizer in rows at desired depth and seed to seed spacing, cover the seeds with soil and provide proper compaction over the seeds .The recommended row to row spacing, seed rate, seed to seed spacing and depth of seed placement vary from crop to crop and for different agro-climatic conditions to achieve optimum yields.
