Productivity enhancement of Indian mustard (Brassica juncea) through innovative crop establishment technique

Abstract

A field experiment was carried-out for two consecutive years 2016-17 and 2017-18 during winter at ICARDirectorate of Rapeseed and Mustard Research, Bharatpur, Rajasthan to evaluate the performance of Indian mustard (Brassica juncea L.) under innovative transplanting technique of crop establishment. The experiment was laid out in randomized block design with two factors, i) planting geometries, i.e. 30 × 30 cm (T1), 45 × 30 cm (T2) and 60 × 30 cm (T3) and ii) transplanting dates, i.e. 13th October (D1), 22nd October (D2) and 01st November (D3) with three replications. The maximum plant height (199.2 cm), leaf area index (5.82) and chlorophyll content (43.29) were recorded with T2 and D1 during both the years. The significantly higher value of yield attributes, i.e. length of siliquae, number of seeds/siliquae, test weight and oil content were also recorded with T2D1 treatment during both years. Seed yield was recorded maximum with T2D1 treatment during both the years. Seed yield improved significantly with T2 by 9.1 and 19.5% over T1 and T3 respectively, whereas, yield improvement with D1 also recorded significantly higher by 8.3 and 32.2% over D2 and D3, respectively. The maximum net returns (` 100835) and B:C ratio (3.77) was also found with T2 than the other treatments. Among the date of transplanting treatments, D1 recorded the maximum values of these monetary parameters. Thus, we can conclude that transplanting of mustard on 13th October with 45 × 30 cm planting geometry is beneficial for getting higher yield as well as net monetary returns in the Rajasthan.

Assessment of System of Mustard Intensification (SMI) with Plant Geometry and Age of the Seedlings in Enhancing Growth and Yield Attributes of Mustard (Brassica juncea L.)

“…The enhanced plant height in mustard under 30 cm × 30 cm spacing over other plant geometry might be due to competition for light at closer spacing as compared to wider spacing under transplanting. Similar results were also reported by Kumar et al [5], Singh et al [6] and Singh et al [7]. The significantly higher plant height under transplanting of 25 days old seedlings may be owing to the fact that optimum age of seedlings performed active growth which might have contributed to more vigorous growth and development.…”

Response of Indian mustard (Brassica juncea) to varying spacing and transplanting in north Gujarat region

“…On the other hand, crop geometries of 45 cm × 30 cm and 45 cm × 45 cm having higher plant population/ unit area resulted in higher seed yield. Our results confirm the findings of and Singh et al (2006); Sahar et al (2012) and Singh et al (2019).…”

“…In the increased population in narrow crop geometry, plants probably tended to be taller for getting light, which may result in increased plant height. Pandey et al (2015) and Singh et al (2019) also reported higher plant height with narrow spacing under transplanted Indian mustard. Among the different spacing, 60 cm × 45 cm accumulated significantly more dry-matter than rest of spacings owing to better growth and development of the individual plants.…”

“…The no significant result was observed Singh et al [16] also reported transplanting of mustard on 13th October was found highly superior with respect to growth, physiological parameters, yield and yield attributes compared to transplanting done on 22nd October and 01st November. interaction of date of sowing and variety grain yield Singh [17] also conducted [18,19].…”
