Micro Irrigation

Investments into drip irrigation systems, while sizeable, appear to pay off quickly as farmers realise a sharp increase in yields, alongside more efficient water use. Drip irrigation is sometimes called trickle irrigation and involves dripping water onto the soil at very low rates (2-20 litres/hour) from a system of small diameter plastic pipes fitted with outlets called emitters or drippers. Water is applied close to plants so that only part of the soil in which the roots grow is wetted, unlike surface and sprinkler irrigation, which involves wetting the whole soil profile. With drip irrigation water, applications are more frequent (usually every 1-3 days) than with other methods and this provides a very favourable high moisture level in the soil in which plants can flourish.

Precision agriculture
Precision agriculture (PA) or satellite farming or site specific crop management (SSCM) is a farming management concept based on observing, measuring and responding to inter and intra-field variability in crops.

Precision agriculture aims to optimize field-level management with regard to:
'Precision agriculture' seems to be the way out for the future.

Mulching
Mulching is one of the simplest and most beneficial practices one can use in the garden. Mulch is simply a protective layer of a material that is spread on top of the soil. Mulches can either be organic -- such as grass clippings, straw, bark chips, and similar materials -- or inorganic -- such as stones, brick chips, and plastic. Both organic and inorganic mulches have numerous benefits:

NTR Jala Siri programme
The department proposes to bring more than 20,000 hectares into the MI system under the flagship NTR Jala Siri programme ('NTR Jala Siri' is the flagship programme of Govt. of Andhra Pradesh with NABARD and MGNREGS with a view to consolidate the gains made in the Land Development Project of the later programme and to ensure sustainable and comprehensive development of the land securing livelihoods. The project aims at providing assured source of irrigation to the 10 lakh acres of fallow and uncultivable land belonging to the 6 lakh SC/ST farmers of the state. This will act as a welfare measure in terms of enhancing the productivity of the lands thus maximizing their incomes.) in 2017-18.
