Influence of Organic Nutrient Sources and Hydrogel on Yield Attributes and Productivity of Mustard (Brassica juncea L.)

The experiment was conducted to study the effect of organic manures and hydrogel on growth and productivity of mustard during the rabi season of 2023-24 at Agronomy Research Farm of School of Agricultural Sciences, Nirwan University, Jaipur, Rajasthan, India. The experiment was laid out in factorial randomized complete block design. There were two factors under the design viz., different organic manures and levels of hydrogel. The first factor had three organic manures viz., FYM @ 5 t/ha, vermicompost @ 2.5 t/ha and poultry manure @ 1 t/ha. The different levels of hydrogel were no hydrogel (control), hydrogel @ 2.5 kg/ha and hydrogel @ 5 kg/ha. The growth and yield attributes as well as yield of mustard was significantly enhanced with the application of vermicompost @ 2.5 t/ha though this treatment was found to be at par with poultry manures @ 1.0 t/ha. Further results showed that the application of hydrogel @ 5.0 kg/ha over hydrogel @ 2.5 kg/ha and control significantly enhanced the productivity of mustard crop in the semi-arid areas of Rajasthan. The present study highlights the influence of organic nutrient sources and hydrogel on yield attributes and productivity of mustard (Brassica juncea L.).
