“…more number of primary and secondary branches and leaf area. Literature showed that mustard crop geometry of 45 cm row to row and 15 cm plant to plant resulted into more number of branches/plant (Mirza et al 2008;Paraye et al 2009, Pandey et al 2015, crop growth rate (CGR) and above ground dry biomass accumulation (Tyagi and Upadhyay 2016). Mustard Planter sown crop retained more chlorophyll and leaf relative water content might be due more water allocation to the plants at optimum population, and favourable land configuration facilitated more light interception, less transpiration and less evaporation due to soil mulch (Singh et al 2015).…”

Indian mustard [Brassica juncea (L.) Czern & Coss.] is traditionally sown either by broadcasting or with ordinary wheat seed drill having drawbacks of high seed rate, seed breakage, less seed germination, uneven and dense plant population resulting into low seed yield. A Mustard Planter was developed and evaluated at research station as well as farmers' field against wheat seed drill (farmer's practice) during 2016-18 to vanquish the pre-taxed constraints in Indian mustard. Results showed significant improvement in branches per plant, girth of basal node, leaf area index (LAI), relative water content (RWC), seed yield, harvest index, test weight and accrued higher benefit margin in the station trials. Farmer's field trials also recorded optimum plant population, higher plant height, branches per plant and stem girth. Mustard Planter sown crop recorded more seed yield (+9-22%), harvest index (+11.7%), Test weight (+13.6%), net return (+13.3-30.6%) and B/C ratio (+16%) in the station as well as farmer's field trials. The fields sown with Mustard Planter also conserved soil moisture (>100%) over wheat seed drill in 0-60 cm soil depth during the crop mid-season. The results endorsed that the Mustard Planter is an efficient seeding machine for sowing of rapeseed-mustard in the rainfed situation and may be recommended for its wider adaptability in the region for the benefit of the farmers.

“…The lowest secondary branches per plant were found in 15 cm row spacing. Pandey et al, (2015) in a field experiment had also reported that the number of secondary branches was recorded significantly higher with crop geometry of 45cm x 15cm as compared to other crop geometries. Varieties and the interaction effect of plant geometry and varieties on primary branches per plant were found to be nonsignificant.…”

“…Wider row spacing of 45 cm recorded significantly taller plants than narrow row spacing of 15 cm and it was at par with 30 cm row spacing. Pandey et al, (2015) had also reported that the plant height was significantly higher with crop geometry of 45cm x 15cm as compared to other crop geometries. The plant height was not significantly influenced by varieties and interaction of varieties and plant geometry.…”

The field experiment was carried out during winter of 2018/19 with two varieties (Unnati and Surkhet-Local) and three plant geometry (15cm × 10 cm, 30cm × 10 cm, 45cm × 10cm) in Randomized complete block design (RCBD) with four replications. Statistically there was no difference between two varieties while differences were found on different spacing and interaction between variety and spacing on final seed yield. High significant differences on seed yield was due to spacing and yield of rapeseed were higher at the 30 cm inter row spacing as compared to the 15 cm and 45 cm inter row spacing. Statistically significant effect was found on mean values of seed yield for interaction which showed that Unnati cultivar in 30 cm x 10 cm plant geometry had the highest seed yield (969.86 kg/ha) followed by Surkhet-local with spacing of 15 cm × 10 cm (843.75 kg/ha) and 30 cm × 10 cm (823.76 kg/ha). Yield of these varieties decreased as spacing is increased, thus sowing of Unnati should be done at cropping geometry of 30 cm × 10 cm and for Surkhet-local it should not be done beyond 30 cm inter row spacing to get the maximum potential yield.

“…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.…”

A field experiment was conducted at Castor Mustard Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat during the winter (rabi) season of 2020–21, to study the response of Indian mustard [Brassica juncea (L.) Czernj.] to different spacing and transplanting schedule in north Gujarat. The experiment was conducted in a split-plot design with 4 spacing in the main plots and 3 transplanting dates in the subplots, that were replicated 3 times. The maximum plant height at harvesting (189.18 cm) and crop-growth rate (11.69 g/plant/day) at 30–60 days after transplanting (DAT) were recorded with narrow spacing of 45 cm × 30 cm and higher dry-matter accumulation at 30 and 60 DAT (11.57 and 71.70 g/plant respectively) were recorded at 60 cm × 45 cm spacing. Indian mustard transplanted at 45 cm × 30 cm spacing recorded significantly higher seed yield (2,187.1 kg/ha), being statistically at par with spacing 45 cm × 45 cm spacing (2,070.4 kg/ha). In terms of seed yield, the crop transplanted on 10 November (2,142.7 kg/ha) outperformed the crop transplanted on 20 November (1,829.0 kg/ha), but it was statistically on a par with the crop transplanted on 31 October (1,996 kg/ha). The higher net returns (`61,227/ha), production efficiency (19.59 kg/ha/day) and economic efficiency (`548.5/ha/ day) were registered at 45 cm × 30 cm spacing. Significantly higher net return realization (`63,596/ha), production efficiency (19.13 kg/ha/day) and economic efficiency (`567.8 /ha/day) were noted under 10 November transplanting.
