The experiment was conducted to find out the effect of foliar application of NAA on yield and economics of ber (Ziziphus mauritiana Lamk.) cv. Gola at Bharatpur, Rajasthan. Foliar application of plant growth regulator Nephthalene acetic acid (NAA of an auxin group) @ 10 ppm twice in second week of October and November recorded higher yield of fruits (136.5 q/ha) as compared the yield (121.68 q/ha) recorded in control (farmer’s practice). There was 12.18 % increase in yield over control. The technology gap in productivity (13.5 q/ha) was computed. The Technology index value (9.0 %) was recorded. By conducting on-farms testing of proven technology of foliar application of plant growth regulator NAA, yield potential of ber can be increased by reduction in flower and fruit drop
