India is the second largest producer of groundnuts in the world. The major growing state for groundnut is Gujarat, Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra Rajasthan, Madhya Pradesh, Orissa, and Uttar Pradesh. The world average yield is around 1300 kg ha-1 and about 70% of the world groundnut production occurs in the semi-arid tropics where the average yield is just around 800 kg ha-1. The study was conducted to relate the crop parameters with design of machine. Development of combine for threshed crop requires the data of plant height and weight of the plant in order to carry the crop and drop in the thresher. So, the present study was undertaken in order to design the machine. Selected crop parameters taken at 30, 60, 90 days after sowing and at the time of harvest like Plant Height, Width of Plant, Root Length, Number of pods, Number of unfilled pods and number of plants were measured in relation to design of machine. The minimum and maximum temperature requirements of groundnut are not well established but it germinates more quickly within range of 20-35oC with optimum temperature between 30-33oC for most rapid germination and seedling development. The results shown that the average Plant Height, Width of Plant, Root Length, Number of pods, Number of filled pods, Number of unfilled pods and number of plants are 35cm, 17cm, 25cm, 22, 15, 7 and 17 respectively were recorded at the time of harvest (100-120days of sowing). The pod weight increases in a linear fashion during pod filling and the linear growth rate continues until near harvest.
