Assessment of hybrid Summer Tomato production at late winter sowings


Journal of Sylhet Agricultural University, 2019, Volume 6, Number 1 and 2; Pages: 41-45

An experiment was carried out to assess the influence of two sowing dates on growth and yield of hybrids tomato during summer season at the experimental field of Horticulture department, Sylhet Agricultural University, Sylhet using RCBD with three replications during January to June, 2018. In this study, four tomato hybrids viz., BARI Hybrid Tomato-3, BARI Hybrid Tomato-4, BARI Hybrid Tomato-8 and BARI Hybrid Tomato-10 were grown at two different sowing dates i.e. 2 January and 1 February. Tomato hybrids had showed significant variations on inflorescence characteristics, fruit qualities and yield attributes of tomato during late winter. Almost similar fruit yields were recorded from January and February sowing (43.86 t ha-1 and 43.52 t ha-1, respectively) indicating bright scope of growing tomato in late winter. The highest fruit weight plant-1 as well as fruit yield per hectare and number of fruit plant-1 were obtained from BARI Hybrid Tomato-4 (1.59 kg plant-1, 54.06 t ha-1 and 31.83, respectively) while the lowest yield was found in BARI Hybrid Tomato-3 (1.08 kg plant-1, 36.72 t ha-1 and 19.83, respectively). The heaviest individual fruit was found in BARI Hybrid Tomato-10. The interaction effect had significant influence on growth and yield of tomato production. The highest fruit weight plant-1 and fruit yield per hectare (1.66 kg plant-1 and 56.44 t ha-1 , respectively) was found from BARI Hybrid Tomato-4 on January sowing whereas the lowest was found in BARI Hybrid Tomato-3 on February sowing (1.05 kg plant-1 and 35.70 t ha-1).

INFLUENCE OF SOWING DATES ON GROWTH AND YIELD OF MUNGBEAN VARIETIES IN SYLHET


Journal of Sylhet Agricultural University, 2017, Volume 4, Number 2; Pages: 233-238

An experiment was conducted in the Agronomy Field Laboratory, Sylhet Agricultural University, Sylhet, Bangladesh during the period from January to December 2013 to investigate the performance of mungbean varieties viz., BARI Mung-5 (V2) and BARI Mung-6 (V1) as influenced by sowing dates from January (S1) to December (S12). The experiment was conducted in a Randomized Complete Block Design (RCBD) with three replications assigning the sowing dates and varieties on the plots. Unit plot size was 10 m2 (4.0 m × 2.5 m) with a plant spacing of 30 cm × 10 cm. On an average about 60 days after sowing (DAS) mungbean pods were harvested two times within 10 (ten) days interval for each of the sowing dates. The results of the experiment showed that variety had no significant influence but sowing date and their interaction exerted significant influence on the yield and yield contributing characters of mungbean including plant m-2, number of branches plant-1, number of pods plant-1, number of seeds pod-1, pod length, 1000 seed weight, grain yield, stover yield and harvest index. BARI Mung-6 produced higher yield and yield contributing characters compared to BARI Mung-5. The highest seed yield 693.1 kg ha-1 was obtained from 20 March sowing and the lowest seed yield 196.1 kg ha-1 was obtained from 05 June sowing (S6). It was also found that, both of the varieties gave highest yield on 20 March sowing (S3) and also indicated that yield and yield attributing characters of mungbean were affected for delayed sowing from 20 March. It may be recommend that in Sylhet the mungbean could be cultivated in the month of March, April, June, July and September on the other hand, it should not be cultivated in the month of January, February, November and December due to unavailability of rainfall or moisture and May, August and October for excessive rainfall.

EFFECT OF SOWING DATES AND VARIETIES ON STEMPHYLIUM BLIGHT OF LENTIL


Journal of Sylhet Agricultural University, 2017, Volume 4, Number 2; Pages: 199-205

A research work was carried out with a view to evaluate lentil (Lens culinaris) varieties at different sowing dates from October 25 to December 6 against Stemphylium botryosum in Bangladesh during winter season of 2012-2013.Two lentil varieties viz., BARI Masur-1 and BARI Masur-7 were evaluated at seven different sowing dates viz., October 25, November 1, November 8, November 15, November 22, November 29 and December 6 in RCB design with three replications. Significant differences were found in percent disease incidence for sowing dates and varieties. The highest disease incidence (72.50%) was recorded from the plants grown from October 25 sowing which was statistically identical to that of November 1 (63.5%), November 15 (62.17%) and November 22 (62.17%). However, disease incidence was drastically reduced at November 29 (42.17%) and December 6 (30.83%) sowings. The variety BARI Masur-1 was found more sensitive (64.0%) to that of BARI Masur-7 (47.0%) to stemphylium disease. The average highest seed yield was obtained from November 8 sowing (1200 kg ha-1) which was statistically identical to that of November 15 sowing (1156 kg ha-1). Between two varieties, BARI Masur-7 was more productive (1131 kg ha-1) than that of BARI Masur-1 (789 kg ha-1). The maximum seed yield ha-1 (1399 kg) was achieved from BARI Masur-7 when grown from November 8 sowing followed by November 15 sowing (1314 kg ha-1) by the same variety indicating first fortnight of November might be more productive for BARI Masur-7.
