Hedayetullah, hedaye.bckv@gmail.com An experiment was conducted at the Crop Museum Farm, College of Agriculture, Tripura during the period from November 2014 to March 2015 to study the effect of varietal performance of transplanted mustard under acidic condition. The treatments included five varieties viz. Jhumka, B-9, Bhabani, PPS-1, and Pitambari. The experiment was laid out in a Randomized Block Design with four replications. The highest plant height (137 cm) was observed in Jhumka treatment at harvest stage followed by PPS-1 treatment and the maximum dry matter accumulation (11.54 g plant -1 ) was observed in PPS-1 treatment at harvest stage followed by Jhumka. The maximum number (334 nos) of siliqua per plant was observed in Bhabani variety but length of siliqua was measured less (5.95 cm) compared to others treatments. The maximum number of seeds per siliqua (27.63 nos) was obtained in Pitambari treatment where lowest was observed in B-9 variety. The maximum seed yield (6.68 q ha -1 ) was obtained PPS-1 variety and lowest yield (4.69 q ha -1 ) was obtained in Jhumka variety. The present study was to assess the yield performance and early harvest of five mustard cultivars under acidic soil condition in hilly tract of Tripura. Keywords: Transplanted rapeseed and mustard, Variety, Seed yield Introduction Rapeseed and mustard is an important and widely grown oil seed crop in India next to groundnut. The average productivity is 1152 Kg ha -1 as against world average of 1400 Kg ha -1. The major reasons for low yield are lack of proper varietal selection and long duration. Transplanted mustard gives more yields compared to the direct seeded mustard and the crop can also be harvested one week earlier. The total crop duration including nursery, no extra time is required. It is advantageous to the farmers who take second crop as mustard just after harvesting of paddy or others kharif crops. Farmers can adopt this method to take a second crop where time is limited for sowing mustard to compensate days nursery time period. 1 Assistant Professor, Department of Agronomy, Bidhan Chandra Krishi Viswavidyalaya (BCKV), Mohanpur , Nadia, W.B. 2 Assistant Professor, College of Agriculture, Tripura, Lembucherra, West Tripura Associate Professor, College of Agriculture, Tripura, Lembucherra, West Tripura

3 Int. J. of Agron. & Crop. Sci Md. Hedayetullah et al., 2016 Therefore, our objective of this current study was to assess the yield performance and early harvest of five mustard cultivars under acidic soil condition in hilly tract of Tripura. Materials and Methods An experiment was conducted at the Crop Museum Farm, College of Agriculture, Tripura during the period from November 2014 to March 2015 to study the effect of varietal performance of transplanted mustard under acidic condition. The treatments included five varieties viz. Jhumka, B-9, Bhabani, PPS-1 and Pitambari. The experiment was laid out in a Randomized Block Design with four replications. Plant samples were collected at an interval of 30 days after sowing from three randomly selected locations in each. Ten plant samples were uprooted randomly from each plot under different treatments to determine the growth attributes like plant height and dry matter accumulation per plant and yield attributes like no of siliqua per plant, length of siliqua, no of seeds per siliqua and seed yield. Similarly, 10 plants from each plot were randomly selected. The plant height was recorded from the base above the ground to the tip of the stem using a scale. The total number of filled siliqua per plant was recorded at harvest, while the total number of seeds per siliqua was recorded by randomly selecting 10 siliqua from each plant per plot at harvest. The seed grain yield of each 1 m 1 m plot segmented from the 5 m 5 m plot was recorded by harvesting plants, followed by sun-drying, threshing and cleaning on the threshing floor. The seed yield was recorded in q ha -1. For interpreting the effect of different treatments under different cases, for comparison of F values and at 5% level of Significance, Fisher and Yates Table were followed. Results and Discussion Growth Attributes Plant Height (cm) Plant height increased with progress of age. The highest plant height ( cm) was observed in PPS-1 treatment at 30 DAT (Days after transplanting) followed by Bhabani treatment (Figure 1). The similar trend of plant height was also recorded in PPS-1 treatment ( cm) at 60 DAT and minimum plant height was recorded in Pitambari treatment (Figure 1). The highest plant height ( 137 cm) was observed in Jhumka treatment at harvest stage followed by PPS-1 treatment (Figure 1). Lipu et al. (2013) also reported that the similar trend of growth. Dry Matter Accumulation (gm Plant -1 ) Dry matter accumulation increased with progress of growth stage. The maximum dry matter accumulation (4.33 g plant -1 ) was Figure 1: Effect of Rapeseed and Mustard Varieties on Plant Height (cm) in Different Stages 41

Hedayetullah et al., 2016 Figure 2: Effect of Rapeseed and Mustard Varieties on Dry Matter Accumulation (gm Plant -1 ) in Different Stages observed in PPS-1 treatment at 30 DAS followed by Bhabani ( 3.69 g plant -1 ) treatment (Figure 2). The minimum dry matter accumulation (3.03 gm plant -1 ) was observed in Pitambari treatment at 30 DAT. Similarly, in 60 DAT the maximum dry matter accumulation (8.46 g plant -1 ) per plant was obtained in PPS-1 variety and minimum dry matter accumulation (6.35 g plant -1 ) was observed in B-9 treatment (Figure 2). The maximum dry matter accumulation (11.54 g plant -1 ) was observed in PPS-1 treatment at harvest stage followed by Jhumka (Figure 2). The minimum dry matter accumulation (9.13 gm plant -1 ) was observed in Bhabani treatment at harvest stage. Lipu et al. (2013) also reported that the similar trend of dry matter accumulation. Yield Attributes Number of Siliqua Plant -1 Number of siliqua/plant varied significantly due to varieties. The result revealed that maximum number (334 nos) of siliqua per plant was observed in Bhabani variety which was significantly higher than Jhumka ( Table 1: Effect of Rapeseed and Mustard Varieties on Yield Attributes at Harvest Stage Treatments No of Siliqua Plant -1 nos), B 9 ( nos), PPS 1 (139 nos) and Pitambari ( nos). The siliqua numbers of Jhumka is statistically at par with B 9 and PPS 1 (Table 1). Length of Siliqua (cm) Length of Siliqua (cm) Length of siliqua was measured less (5.95 cm) compared to other varieties. The number of seeds per siliqua contributes considerably towards the final seed yield. The number of seeds per siliqua differed significantly among the varieties. Highest number of seeds per siliqua was obtained from Pitambari (27.63) followed by PPS 1 (19.88), Bhabani (17.83), Jhumka (17.00) and lowest seeds/siliqua was obtained by B 9 (15.25) (Table 1). Datta et al. (2012) also found the similar trend in other mustard varieties. Number of Seeds Siliqua -1 No of Seeds Siliqua -1 Seed Yield q ha -1 Jhumka B Bhabani PPS Pitambari SEM (±) CD (5%) Note: SEM = Standard Error of Mean; CD = Critical Diference; cm = centimetre; q ha -1 = quintal per hectare. It is evident from Table 1 that the maximum number of seeds per siliqua (27.63 nos) was recorded in Pitambari variety followed by PPS-1 (19.88 nos) treatment and the minimum numbers was recorded in B-9 42

5 Int. J. of Agron. & Crop. Sci Md. Hedayetullah et al., 2016 treatment (15.25 nos) (Table 1). Datta et al. (2012) also found the similar trend. Seed Yield q ha -1 The maximum seed yield (6.68 q ha -1 ) was obtained by PPS-1 variety and lowest yield (4.69 q ha -1 ) was obtained in Jhumka variety (Table 1). The similar results were also found by Alam and Rahman (2006) and Mamun (2005). Seed yield was affected significantly due to variation of varieties but variety Jhumka which obtained lowest seed yield is statically at par with varieties B 9 (5.32 q ha -1 ), Pitambari (5.23 q ha -1 ), Bhabani (5.08 q ha -1 ). Increase in seed yield was due to the better genetic makeup and growth parameters and yield attributes. The results of this experiment are supported by Pati and Achariya (2009). Our present investigation revealed that the best variety of the five mustard varieties under the acidic hilly soil was PPS-1 based on attributes of growth, morphophysiology and yield. References 1.
