Abstract :
The study was conducted to evaluate the
performance of organic fertilizers on cotton yield and
soil nutrients at Cotton Research Farm of Cotton
Development Board located at Jagodishpur,
Chawgacha, Jashore during the crop growing season of
2021 and 2022 using the seeds of genotype CB Hybrid-1
planted in a spacing of 90 × 35 cm. The experiment was
laid out in a RCBD design with three replications. The
experimental treatments were consisted of different
doses of cow dung and processed organic fertilizers of
three different sources (a, b and c). The treatments
were: T1 = control (zero fertilizer), T2 = 10.526 t ha-1
of
cow dung, T3 = 3.571 t ha-1
of processed organic
fertilizer (a), T4 = 4.225 t ha-1 of processed organic
fertilizer (b), T5 = 5.0 t ha-1
of processed organic
fertilizer (c), T6 = 1⁄2 cow dung + 1⁄2 recommended
fertilizer dose (RFD) of N, P, K, S, B, Zn and Mg, T7 =
1⁄2 (a) + 1⁄2 RFD of N, P, K, S, B, Zn and Mg, T8 = 1⁄2 (b) +
1⁄2 RFD of N, P, K, S, B, Zn and Mg and T9 = 1⁄2 (c) + 1⁄2
RFD of N, P, K, S, B, Zn and Mg. The trend of nutrients
was smaller but increase was observed. The highest
increase of total OM, total N, P, K, S, Zn and B were
7.89%, 10.0%, 8.27%, 9.09%, 9.0%, 8.81%, 8.33%
respectively and those were recorded in T5, T2, T6, T3,
T7, T7 and T5 treatments respectively in the end of
second year. The results indicated that the half amount
of organic fertilizer (b) along with 1⁄2 RFD (T8) produced
the maximum seed cotton (2.49 t/ha) in 2021. But sole
organic fertilizer at the rate of 4.225 t ha-1
(source- b)
produced maximum seed cotton (2.51 t/ha) in 2022.
Amendment of sole cow dung gave maximum BCR of
2.34 and 2.69 in 2021 and 2022 respectively. The
treatments T3, T6, T7 and T8 might be the optimum
treatment on the basis of BCR. Application of organic
fertilizer with inorganic offers higher yield of seed
cotton and economic returns with an increase of soil
nutrients.
