To investigates the impact of biostimulants and organic mulch on enhancing the growth,
flowering, and yield of the strawberry cv. ‘Katrain Sweet’, an experiment was carried out in the
Garden, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and
Technology, Kanpur, during two subsequent years i.e.,2022-2023 and 2023-2024 is randomized
block design using13 treatments (T 1 -Azotobacter (5g/plant) + Trichoderma harzianum (5g/plant)
+ paddy straw, T 2 -Azotobacter (8g/plant) + Trichoderma harzianum (6g/ plant) + paddy straw,
T 3 -Azotobacter (5g/plant) + Trichoderma harzianum (5g/plant) + dried leaves, T 4 -Azotobacter
(8g/plant) + Trichoderma harzianum (6g/plant) + dried leaves, T 5 -Azotobacter (5g/plant) + PSB
(5g/plant) + paddy straw, T 6 -Azotobacter (8g/plant) + PSB (8g/plant) + paddy straw, T 7 –
Azotobacter (5g/plant) + PSB (5g/plant) + dried leaves, T 8 -Azotobacter (8g/plant) + PSB
(8g/plant) + dried leaves, T 9 -Azotobacter (5g/plant) + PSB (5g/plant) + Trichoderma harzianum
(5g/plant) + paddy straw, T 10 -Azotobacter (8g/plant) + PSB(8g/plant) + Trichoderma harzianum
(6g/plant) + paddy straw, T 11 -Azotobacter (5g/plant) + PSB (5g/plant) + Trichoderma harzianum
(5g/plant) + dried leaves, T 12 -Azotobacter (8g/plant) + PSB (8g/plant) + Trichoderma harzianum
(6g/plant) + dried leaves, T 13 -Control), each replicated at least three times. The results showed
substantial enhancements in vegetative and reproductive characteristics along with yield when
Azotobacter, Trichoderma harzianum and Phosphorous Solubilizing Bacteria (PSB)were applied
in combined with organic mulch, particularly in treatment T 12 -Azotobacter (8g/plant) + PSB
(8g/plant) + Trichoderma harzianum(6g/plant) + dried leaves, the maximum influence was
recorded for these parameters. The findings underscore the potential for the use of biostimulants
and organic mulches to enhance strawberry production, offering a sustainable approach for
improving yield and plant growth.
