The pressurised (drip) irrigation technology and its adoption to meet the food security with increasing water productivity and decreasing evapotranspiration, assured the release of abundant stress of the limited water resources. To increase the agricultural productivity to meet future food challenges and sustain the ground water resources of Andhra Pradesh, the government has launched APMIP (Andhra Pradesh Micro Irrigation Project).

The developed implement was operated by the mini-tractor using three-point hitch, it performs both the operations of installation and retrieval of drip line. The performance was evaluated on the basis of various field parameters, operating parameters and performance parameters. The experiment was carried out in F-RBD design having two factors and four replications with three different levels of each factor. The factors namely spool rotation (35-53, 53-71 and 71-89 rpm) and forward speed (2.03.0, 3.0-4.0 and 4.0-5.0 kmph) were taken for an experiment.

The mini-tractor operated drip lateral installer and retriever was fabricated at department of farm machinery and power engineering, CAET, Junagadh agricultural university, Junagadh. A drip line installer and retriever were developed for small fields. One operator can install drip line on or just beneath the soil surface to precisely irrigate crops after planting and retrieve the drip line after irrigation is no longer needed for the season.

While the country has made large strides in achieving the agricultural development goals of food security, availability and accessibility, it is still being challenged by many social, economic and environment factors such as increase in population, declining land resources, increasing urbanisation, increasing demand of food due to rising income and transition of youth from farming to non-farming sector.

An attempt was made to study the soil water movement under two type of plastic mulch (black and white) with drip irrigated eggplant on a line source dripper. Both spatial and temporal variation of wetting pattern was determined in sandy loam soil using surfer 15 software. The layout of the experiment was three treatments tested, black mulched drip irrigation (BM+DI), white mulched drip irrigation (WM+DI) and drip irrigation without mulching. The results of the study indicated that DI + BM and DI + WM treatments distinctly decreased water applied in the order of DI + WM < DI + BM < DI.

This paper presents a prediction model developed using dimensional analysis for friction losses in drip irrigation laterals. Drip irrigation laterals with cylindrical type in-line emitters placed at different spacings ranging from 0.2 to 1 m were considered.

Trickle irrigation systems’ efficiency depends on system uniformity, which is determined by water discharge uniformity from emitters. It is impossible to produce 2 identical emitters due to manufacturing variations. The manufacturer’s coefficient of variance is used as a measure of discharge variations of emitters.
