Agriculture has.play.d an important role in the growth of the Indian economy. Water and electricity.are es.ential inputs.for agriculture today. India produces.the third-larges. amount of electricity.in the world, behind China and the Us.. As.an incentive to increas. production, mos. s.ates.provide free electricity.to farmers. Free electricity.has.decreas.d groundwater levels.and increas.d electricity.cons.mption. The objective of this.s.udy.was.to find out the factors.that influenced farmers.to adopt a s.lar water-pumping s.s.em in Gujarat. The s.mples.were randomly.s.lected. This.s.udy.examined the entire s.ate of Gujarat. One hundred and fifty.farmers.who adopted s.lar water-pumping s.s.ems.were interviewed, including 50 banana farmers. 50 cotton farmers.and 50 groundnut farmers. Primary.data were collected through an interview. The adoption of s.lar water-pumping s.s.ems.by.farmers.was.identified us.ng factor analy.0}s. s.s. s.ftware was.us.d to analy.0} the data collected. In this.s.udy. only.two factors.contributed to the variance of 59.469%. The adoption of s.lar water pumps.by.farmers.was.influenced by.government policy.and economic benefits. An economic benefit variance of 33.20% was.found, while a government policy.variance was.26.27%. A s.lar water-pumping s.s.em has.low initial cos.s. flexible credit policies.motivate adoption, s.lar water-pumping s.s.ems.can s.ve electricity. and maintenance and repair cos.s.are affordable. Government policy.that includes.s.lar water-pumping s.s.ems.is.motivated by.awarenes., s.bs.dies.for adoption and a fair price to s.ll energy.s.rplus.s. Farmers.are recommended to adopt a s.lar water-pumping s.s.em in conjunction with a drip irrigation s.s.em to receive additional income. The s.cces.ful s.heme will be recommended to other s.ates.in India for implementation. The factors.that influence farmers.to adopt a s.lar water-pumping s.s.em in Gujarat, India are identified bas.d on interviews.with one hundred and fifty.randomly.s.l
