Effect of different soil moisture regimes and salinity level on growth and yield in mustard

Abstract

Soil moisture stress and salinity resulted reduction in almost all the growth, yield and yield attributes in mustard var. RH-30. Salinity behaved similarly to soil moisture stress and the magnitude of reduction increased with the increase in their level accordingly. Chloride type of toxicity was found to be more harmful than that of sulphate toxicity. The results obtained in the present study suggested that maintenance of wetter irrigation under salinity could go a long way in maximizing the crop production in mustard

Analysis of Drought Susceptibility Index in Indian Mustard [Brassica juncea (L.) Czern and Coss]

“…The reduction in grain yield can be ascribed to the relative more reduction in the growth parameters including stem, root and leaf growth, further decreasing number of siliqua per plant, siliqua length and 1000 seed weight. Quantitative aspects as well as the quality of the produce (as there were observed reductions in the oil content of the seeds as well) were adversely affected by moisture stress (Singh et al, 2019). The decrease in siliqua per plant and seed yield recorded in our study is in confirmation with the study of Mirzaei et al (2013) who stated that moisture stress had significant effect on seed yield, number of seeds/pod, number of pod per plant, number of branches per plant, 1000-seed weight, plant height and oil content of cultivars (Hyola-401, Hyola-308, Zarfam and PF) in Iran.…”

“…Low water availability during stem elongation, flowering and pod development causes reduction of pods per plant leading to, grain yield reduction (Gunasekara et al, 2006). Despite India being third largest producer of rapeseed-mustard in the world with large area under oilseed cultivation, production is not keeping pace with population (Singh et al, 2019). Limited efforts have been made towards improving drought tolerance of this crop.…”
