Effect of Soil Test Crop Response Based Long-Term Fertilization on Yield Attributing Parameters and Yield of Wheat (Triticum aestivum L.)

Abstract

A field experiment was carried out during Rabi season of 2020‒2021 and 2021‒2022 at the Jawaharlal Nehru Krishi Vishwa Vidyalaya (JNKVV), Jabalpur (Madhya Pradesh) at research field of department of soil science to find out the effect of soil test crop response based long-term fertilization on yield attributing parameters and yield of wheat. The treatments details were T1; Control, T2 ; 120 N: 80 P2O5: 60 K2O kg ha-1 , T3; Target yield of 4.5 t ha-1, T4; Target yield of 6.0 t ha-1, T5; Target yield of 4.5 t+FYM 5 t ha-1; T6; Target yield of 6.0 t+FYM 5 t ha-1 and carried out in Randomized Block Design (RBD) with four replications. Research findings of long term field experiment revealed that application of soil test crop response recommendation for target yield of 6.0 t ha-1+FYM 5 t ha-1 gave maximum earhead length (14.59 and 14.10 cm), number of grains ear-1 (66.46 and 63.30), test weight (41.93 and 41.35 g), grain yield (5568 and 5052 kg ha-1) and straw yield (7315 and 5969 kg ha-1) of wheat. The balanced application of fertilizers by the soil and the crop's needs for potential growth and development may account for the increased yield under the STCR technique with and without FYM. The inclusion of FYM resulted in a potential movement of water, air, temperature, and nutrients in the soil, which may have improved the conditioning of the rhizospheric environment and further raised yield when integrated with STCR. Due to better physical, chemical, and biological characteristics, enhanced microbial activity and the conversion of inaccessible nutrients into available forms, this STCR technique also aids in higher production.
