A Field experiment was conducted at college form, agricultural college bapatla in clay loam soils during Rabi 2013-14 to study the effects of Ethrel, kinetin and boron foliar application on physiology of growth, development and yield of chickpea (Var. KAK 2) in randomized block design with eight treatments viz., 250ppm Ethrel at 25 DAS (T1), 10 ppm kinetin at 35 DAS (T2), 0.25% boron at 45 DAS (T3), 250 ppm Ethrel at 25DAS + 10 ppm Kinetin at 35DAS (T4), 10 ppm Kinetin at 35DAS + 0.25% boron at 45 DAS (T5), 250 ppm Ethrel at 25DAS + 0.25% boron at 45 DAS (T6), 250 ppm Ethrel at 25DAS + 10 ppm Kinetin at 35DAS + 0.25% boron at 45 DAS (T7) and control (without sprays-T8) in three replications. The spray of 10 ppm kinetin at 35DAS + 0.25% boron at 45 DAS (T5) exhibited higher performance in increasing plant height by 19.8% over control followed by T2 (11.3%). The highest number of branches plant-1 (67.3%) over control was obtained with 10 ppm kinetin spray at 35 DAS (T2). The number of flowers plant-1 increased with Ethrel (16.3%), kinetin (12%) and Ethrel + kinetin (11.9%) sprays compared to control. the less Flower drop and flower abortion was recorded in plants treated with 250ppm Ethrel compared to control. The spray of 0.25% boron enhance total dry matter plant-1 by 62.4% and spray of 250 ppm Ethrel at 25 DAS + 0.25% boron at 45 DAS enhanced it by 49% over control.0.25% boron spray at 45 DAS and spray of 250 ppm Ethrel at 25 DAS+ 0.25% boron at 45 DAS exhibited higher CGR (97.5% and 80.3% respectively) compared to control during pod maturation (60 DAS to maturity). Spray of kinetin and Ethrel + kinetin enhanced RGR by 22.8 and 17.7% during flowering and pod development compared to control, while during pod maturation spray of boron and Ethrel + boron enhanced the RGR. The spray of boron resulted in an increase of 24.7 and 12.6% in pod number plant-1 and 100 seed weight respectively; spray of Ethrel at 25 DAS + Boron at 45 DAS increased the pod yield and seed yield ha-1 by 26.5 and 25.6 % respectively compared to control.
