Influence of agrochemicals on moisture stress mitigation in Indian mustard under rainfed conditions of Jammu

Performance of Salicylic Acid and Hydrogel on Water Use Efficiency and Productivity of Indian Mustard (Brassica juncea L.) in Jammu Region

“…1). Similar, views have been expressed by bharat and co-workers [5] However, application of application of Salicylic acid 100 ppm at flowering stage & siliqua stage (2.09) and application of Hydrogel @ 2.5 kg/ha+ Salicylic acid 200 ppm at flowering stage & siliqua stage with maximum benefit:cost ratio (3.13) was found to be the most economical treatment during both the years of experimentation respectively.…”

“…The Rapeseed Mustard crops suffers moisture stress at various stages of crop growth particularly at the flowering stage and the siliquae formation stage, which are most sensitive to the moisture stress [3,4]. Low soil moisture during the crop growth period due to frequent dry spells at different phases of crop growth results in drastic reduction in the crop yield of Indian mustard thereby resulting in lowered productivity of rapeseed mustard crop [5,6]. The use of hydrogel at the dosage of 2.5 kg to 5.0 kg per hectare have been found promising under rainfed conditions for mitigation of moisture stress at different crop growth stages and have been found to affect the water use efficiency of Indian mustard crop thereby affecting the significant increase in the yield in Jammu region [1].…”

Productivity, Water Use Efficiency and Economics of Indian Mustard (Brassica juncea L.) as Influenced by Integrated Nutrient Management

“…The significant increase in the yield as well as yield attributes may also be due to the fact that 50% flowering stage in Indian mustard is most sensitive stage in terms of nitrogen requirement and moisture availability to the crop results in increased water use efficiency and supply of critical nutrients. Furthermore, split dose of N as top dressing at this stage results in senescence delaying due to elongation of vegetative phase by retaining chlorophyll in the siliquae for longer period of time thereby resulting in improved attribute characteristics which resulted in more sink space and thus more photosynthesis transfer to the storage organs Kumari et al, (2012), Kumar et al, (2006) and Bharat et al, (2017).…”
