Abstract

An experiment was carried out to study the “Assessment of nutrient status in weed due to mulch and weed management practices in chickpea” at Agronomy Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari during rabi seasons of 2021-22 and 2022-23. This experiment aimed to know how much nutrients were removed by weeds from the chickpea field. The experiment was laid out in randomized block design with the factorial concept with twelve treatment combinations comprising of two levels of mulch viz., M0: No mulch and M1: Sugarcane trash mulch @ 5 t ha-1, six levels of weed management practices viz., T1: Pendimethalin @ 450 g ha-1 PE, T2: Pendimethalin @ 450 g ha-1 PE fb hand weeding at 30 DAS, T3: Quizalofop-ethyl @ 40 g ha-1 PoE, T4: Pendimethalin @ 450 g ha-1 PE fb Quizalofop-ethyl @ 40 g ha-1 PoE, T5: Interculture fb hand weeding at 20 and 40 DAS and T6: Weedy check with three replications. The soil of the experimental field was clayey in texture, medium in available nitrogen and phosphorus and rich in available potassium with normal electrical conductivity. Results find that chickpea weeds' N, P and K content was insignificant. In contrast, the uptake of N, P and K by weeds was significantly affected by mulch as well as weed management practices during both the years and in pooled analysis, respectively.

Sugarcane trash mulch, pendimethalin, quazalofop-ethyl, weed management, no mulch

Conclusion

The results concluded that the weeds' lower nutrient removal or uptake in the treatment of sugarcane trash mulch @ 5 t ha-1 and interculture fb hand weeding at 20 and 40 DAS treatment during the study.
