EFFECTS OF FERTILIZERS ON GROWTH AND YIELD OF BORO RICE VARIETIES AT DEKAR HAOR IN SUNAMGANJ DISTRICT


Journal of Sylhet Agricultural University, 2020, Volume 7, Number 2; Pages: 71-77

An experiment was conducted from November 2018 through April 2019 at Noagaon village of South Sunamganj Upazila in Sunamganj District to observe the effects of fertilizers on the growth and yield of boro rice varieties. Two factors experiment was conducted using three rice varieties viz. V1=BRRI dhan28, V2=BRRI dhan29 and V3=BRRI dhan58; and two fertilizers levels viz. F1= N138P22.4K63.5S13.5Zn1.3kg ha-1 (FRG-2012) and F2=N57P12K12kg ha-1 (Farmers’ practice) where Randomized Complete Block Design (RCBD) was followed and replicated thrice. Growth and yield data were recorded. Results of the experiment showed that growth performance was higher in V1 followed by V2. The highest spikelets panicle-1 (253.23) and grains panicle-1 (162.57) were recorded from V2. F1 also gave a higher performance in no. of spikelets panicle-1 (189.81) and grains panicle-1 (132.74) over F2.  The highest 1000 grains weight (22.55 g) was observed in V2 and higher (22.28 g) found in F1. The highest grain yield of 7.66 t ha-1 was produced in V2, and the lowest yield (6.08 t ha-1) was produced in V. The higher yield of 7.18 t ha-1obtained from F1 over F2(6.23 t ha-1). V2 produced the 14 % higher grain yield (8.17 t ha-1) with the application of F1 over F2. The highest BCR (1.54) was found when V2 was treated with F1, and the lowest BCR (1.19) was observed inV1with F2. In comparison to initial soil nutrients status as well as the organic matter was increased in post-harvest soil when applied balanced fertilizers.

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.

INTEGRATED DISEASE MANAGEMENT OF SUMMER GROUNDNUT


Journal of Sylhet Agricultural University, 2015, Volume 2, Number 1; Pages: 43-47

Integrated Disease Management of six different treatment combinations (T0 = Control, T1 = Application of Neem oil extract solution (1: 10 dilution) started from 10 days after sowing (DAS) at 10 days interval, T2 = Application of Dithane M-45 @ 0.2% started from 10 DAS and at 10 days interval, T3 = Application of Sumithion @ 0 .3% started from 10 DAS at 10 days interval, T4 = Integration of Dithane M-45 + Sumithion , T5 = Integration of Dithane M-45 + Sumithion + Neem oil extract) were performed with groundnut varieties (V1: Dhaka-1, V2: Binachinabadam-2 and V3: Binachinabadam-3) to measure the effectiveness of the disease control treatments as well as to get the maximum economic return. Among the treatments, T5 gave the best result along with all three varieties. Treatment T5 gave highest yield of 3061.31 kg ha-1 in Binachinabadam-3. The second best performance was recorded at T4 treatment which received Dithane M-45 + Sumithion and yielded 3001.50 kg ha-1 in Binachinabadam-3. Other yield contributing parameters were also found significantly higher in Binachinabadam-3. Benefit cost ratio (BCR) was highest 2.00 at the combinations of T5V3 and T5V2 followed by T3V3 and T3V2.
