Abstract:
An experiment entitled “Effect of chemicals and agro techniques on growth and flowering of mango cv. Kesar” was carried out at Fruit Research Station, Lalbaug,Junagadh Agricultural University, Junagadh during 2019-20 to 2020-21. Ten different modules arising from different chemical and agro technique, were allocated in randomized block design in three replications. The result revealed that significantly highest number of coppery shoots (317.33, 418.33 and 367.83) was registered with foliar application of GA₃ @ 100 ppm in July + KNO₃ @ 4% in September + KH₂PO₄ @ 1% in October + Ca(NO₃)₂ @ 2% in November during both the years as well as in pooled.Significantly maximum number of panicles (1417.0) were registered in soil drenching with PBZ @ 10 g/tree during July + foliar spray of KNO₃ @ 4% in October + Ca(NO₃)₂ @ 2% in November during first year, but for second year and pooled the maximum number of panicle per tree (1421.0 and 1399.0) was noted in pinching in July + foliar application of KNO₃ @ 4% spray in September + soil drenching with PBZ @ 10 g/tree in October + foliar spray of NAA @ 200 ppm at grain stage. The least days to flowering (50.0, 31.83 and 40.92) and maximum number of hermaphrodite flowers per panicle (307.33, 308.0 and 306.0) were recorded in pinching in July + foliar spray of KNO₃ @ 4% in September + soil drenching with PBZ @ 10 g/tree in October + foliar spray of NAA @ 200 ppm at grain stage during both the years as well as in pooled.
