It has several advantage like weed control, moisture conservation, yield enhancement etcetera. Now a days drip irrigation is become necessity. When mulching is practiced along with drip irrigation, provides best results. At present, Farmers have to lay the drip line and mulching sheet manually. Manual operations are cumbersome and consume much time. Some automatic mulch and drip laying machines were developed but these are not economical. To provide a better option, a mulch sheet cum drip laying machine was developed at PAE, AAU, Dahod for the small farmers. Bullock drawn plastic mulch sheet cum drip laying machine consist of multipurpose tool carrier (main frame), mulch roll carrying unit, dripline roll carrying unit, mulch sheet pressing cum transport wheel, mulch sheet covering unit, mulch sheet punching mechanism. The performance of the machine was evaluated by determining the draft, power requirement, theoretical field capacity, effective field capacity, field efficiency, punching uniformity, punching efficiency and mulch sheet covering. Machine was tested at two levels of mulch width 0.75 m & 1.20 m and three levels of thickness (25, 30, 40 micron). The results were analysed statistically using factorial randomize block design. Average forward speed of developed machine was found as 1.98 km/h. Draft was found minimum (29.14 kgf) for 0.75 m width and 25 micron thickness.EnglishThesis
