Effect of Mycorriza and sulphur on nutrient uptake and yield of mustard (Brassica juncea L.)

Abstract

A field experiment entitled “Effect of Mycorrhiza and sulphur on growth and yield of mustard (Brassica juncea L.)” was conducted during Rabi 2024 at the research farm of Vivekananda Global University, Jaipur, using a Factorial Randomized Block Design with 15 treatment combinations and three replications. The study revealed that the application of 8.0 kg ha⁻¹ Mycorrhiza significantly enhanced growth and yield attributes such as plant height, dry matter accumulation, branches per plant, siliquae per plant, seeds per siliqua, test weight, seed yield (1967 kg ha⁻¹), stover yield (5032 kg ha⁻¹), and nutrient uptake, and also recorded the highest net return (Rs. 63,073) and B:C ratio (2.60), found at par with 6.0 kg ha⁻¹ Mycorrhiza. Similarly, 40 kg ha⁻¹ Sulphur application resulted in significantly better performance across the same parameters, with seed yield (1966 kg ha⁻¹), stover yield (4947 kg ha⁻¹), highest net return (Rs. 61,741), and B:C ratio (2.52), indicating the beneficial role of both Mycorrhiza and Sulphur in improving mustard productivity and profitability.
