Abstract: The experiment was conducted at S.K.N. College of Agriculture Jobner (Rajasthan) on four years old uniform trees of ber cv. Gola during 2018-19 and 2019-20 to study the effect of plant growth regulators and nutrients. Results revealed that application of NAA @ 50 ppm significantly influenced the fruiting attributes viz., fruit set, fruit drop and fruit retention and physico-chemical attributes of ber plant whereas maximum physical attributes viz., fruit diameter, fruit weight, pulp weight, pulp: stone ratio, fruit yield and leaf area were recorded with application of GA₃ @ 50 ppm. Similarly, among nutrients application of K₂SO₄ @ 2 per cent significantly increased the yield attributing characters and fruit yield of ber. Apportioning the combined spray of GA₃ @ 25 ppm applied with K₂SO₄ @ 2 per cent is worth recommendable for farmers of semi-arid region of Rajasthan as it fetched comparable fruit yield, net returns and benefit:cost ratio from ber crop.
