Allison” was conducted on 35 years old kiwifruit vines of uniform size and vigour, planted at a spacing of 4.0 m × 6.0 m at experimental block of Department of Fruit Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (Himachal Pradesh) during the year 2018 and 2019. The entire programme of study was divided into two experiments. In the first experiment, three fertigation levels viz., 100 per cent, 80per centand 60per centrecommended dose of NPK were applied at three application intervals viz., 7 days , 10 days and 15 days according to Randomized Block Design (Factorial). Accordingly, the fertigation was given in 21, 15 and 10 split doses, respectively. Fertigation with 100 per cent recommended dose of NPK in 15 splits at 10 days interval from the emergence of new flush exhibited better vegetative growth performance and nutrient status of soil and leaf. However, the fertigation with 80 per cent recommended dose of NPK in 15 splits at 10 days interval from the emergence of new flush exhibited better bloomintensity, fruit set, yield and quality characteristics. In the second experiment, three fertigation levels (100 %, 80 % and 60 %) of recommended dose of NPK were applied with Arka Microbial Consortium @ 5 ml L-1(single or two applications) in the month of February prior to the emergence of new flush and in Julyaccording to Randomized Block Design (RBD). Fertigation with 100 per cent recommended dose of NPK coupled with two applications of Arka Microbial Consortium @ 5 ml L-1 in the month of February and in July recorded highest bloom intensity, fruit set along with better leaf and soil nutrient status. However, fertigation with 80 per cent recommended dose of NPK coupled with single or two applications of Arka Microbial Consortium @ 5 ml L-1 resulted better performance in terms of kiwifruit yield, yield efficiency and fruit quality parameters namely; fruit size, fruit weight, total soluble solids, TSS: acid ratio, total sugars and nutrient status of leaf and sEnglishSTANDARDIZATION OF FERTIGATION SCHEDULE AND BIO-FERTILIZERS ON GROWTH, YIELD AND QUALITY OF KIWIFRUIT (Actinidia deliciosa Chev.) cv.
