Dry land agriculture plays an important role in the progress of Indian agriculture. The farmers are struggling to maintain timeliness in different unit operations of groundnut to take advantage of favorable situation in dry land conditions of Andhra Pradesh state. It is observed that the yields are expected to decrease by 10-15 per cent, if sowing is delayed by one week, under rain-fed situation. It is absolutely crucial for the seeds that moisture be available in the first few days itself after sowing to achieve 100 per cent germination. Aqua sowing is the simultaneous sowing of seeds and delivery of an equitable quantum of water, just right for the seeds to germinate irrespective of whether it rains or not for the next few days. This is a new technology developed for the benefits of dryland farmers and specially for sowing of seeds during contingency season of delayed monsoon. Seed rates for the groundnut was 105.47, 108.46, 118.55 kg ha-1 with vertical, inclined and horizontal plate seed metering mechanisms respectively. The vertical plate metering mechanism has been selected for sowing in the field. The highest application of water in a test plot of 30 m x 30 m was found to be 120 lit/min. The field capacity was found to be 0.145 ha h-1 for groundnut with field efficiency of 88.90 per cent at an average speed of 2.72 kmph for an aqua planter. The highest pod yield was found to be 619.38 kg ha-1 with discharge rate of 120 lit/min. The cost of sowing with tractor drawn aqua planter was Rs. 751.42 per hour.
