Effects of thinning and irrigation on black cumin growth quality and yield
Abstract
A field experiment observed the effects of different thinning levels and irrigation regimes on black cumin growth, yield and quality. The study was conducted in 2019-2020 at the Spices Research Sub-Centre, BARI, Lalmonirhat, using Randomized Complete Block Design (two-factor). Four thinning levels (T1=1st thinning 25 days after sowing), (T2=2nd thinning 35 days after sowing), (T3=3rd thinning 45 days after sowing), T4=control (no thinning) and three irrigation regimes (I1= vegetative stage + flowering stage), (I2= Vegetative stage + capsule stage), (I3= Vegetative stage + flowering stage + capsule stage) were used as treatment. The results showed that thinning level had a significant effect on plant height (cm) but did not affect yield component, plant population, or quality (thousand grain weight and germination percentage). The combination of second thinning and irrigation regimes (vegetative stage + flowering stage) produced the highest number of branching/plant (5.96), number of capsules/plant (22.38), number of seeds/capsules (75.30), thousand seed weight (3.00g), germination percentage (92.28%). No thinning and all irrigation regimes produced the highest yield, statistically similar to second thinning and all irrigation regimes (vegetative + flowering stage).

Comparative assessment of applicators for urea deep placement in transplanted rice fields
Abstract
A field experiment was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka from December 2015 to April 2016 to evaluate the performance of urea deep placement applicators and observe the yield of boro rice. The experiment consisted of a single factor and the treatments were N0 = Control; UDP-hand = Hand deep placement of urea briquette; SRP-Battery = Deep placement of urea briquette by battery-powered applicator; PU- applicator = Prilled urea deep placement by BRRI applicator; Injector = Deep placement of Urea briquette by injector type applicator; SRP = Deep placement of urea briquette by push- type applicator; PU-broadcast = Prilled urea application by broadcast method. The experiment was laid out in randomized complete block design with three replications. The plant height, number of effective tillers hill-1, grain and straw yield were significantly affected by nitrogen sources and application methods. The application of PU-applicator treatment showed the highest grain and straw yield. Nitrogen sources and application methods significantly affected NH4+ concentration in standing water and soils. Higher levels of soil ammonium concentrations were seen in the treatment of prilled urea applicator during 1–7 days of soil sample collection, while higher levels of water ammonium concentrations were identified in the PU-broadcast treatment. Significantly favorable associations between rice grain production and soil ammonium were found. The findings demonstrated that deep application of pelleted urea using a BRRI applicator outperformed other nitrogen sources and application techniques to increase boro rice grain production.

Differential responses of Boron, Calcium and Zinc on growth and flowering of Lisianthus
Abstract
An experiment was conducted to assess the differential responses of Boron, Calcium and Zinc on the growth and flowering of Lisianthus during the period from January 2021 to May 2021 at Sher-e-Bangla Agricultural University, Bangladesh. The experiment was conducted with a Complete Randomized Design (CRD) with ten replications. Treatments comprising Control, Boron (B), Calcium (Ca), Zinc (Zn), B+Ca, B+Zn, Ca+Zn, B+Ca+Zn were used in the study. Collected data on growth and flower yield attribute parameters showed significant variations. According to the results, the maximum plant height (79.1 cm), stem length (42.7 cm), Peduncle height (12 cm), Stem dia. (6.2 mm), SPAD value (60.9) and 100% rosette free plants were found from the Ca treated plants. The application of Zn also enhanced stem no. (8.9), bud no./plant (28.7), flower dia. (73.5 mm), and weight/stick (11.9 g) of the Lisianthus and decreased the rosetting rate (1.6%) compared to control. From the study, we found that the combination of B+Ca+Zn showed the minimum result on plant height (56.2 cm), stem no (4.8), bud no (16.9), peduncle height (8.0 cm), stem dia (3.6 mm), and SPAD value (52.0). So, in a nutshell, we observed that the sole application of calcium and zinc is best for enhancing lisianthus growth and flower-related attributes.

Assessing the suitability of different intercrops with sugarcane in Dinajpur region of Bangladesh
Abstract
Sugarcane is one of Bangladesh's most important cash cum industrial crops and is the primary source of sugar and goor (jaggery) production in Bangladesh. However, due to land crisis, long duration of crop production and less economic benefit, sugarcane acreage is reducing yearly. Therefore, it is high time to think about how the sugarcane farmers will be benefited. Intercropping with sugarcane generally gives the farmers higher profitability than sole sugarcane cropping. In this study, five different intercropping practices (sugarcane + potato, sugarcane + lentil, sugarcane + cabbage, sugarcane + cauliflower and sugarcane + onion) were compared with the sole sugarcane cropping system for two consecutive years, 2019-20 and 2020-21 in Dinajpur region of Bangladesh. The yield and yield contributing characters, production cost, gross return, net return and BCR were calculated to find the best options among these six treatments. Potato and onion intercropped with sugarcane cv. BSRI Akh 46 is found to be highly profitable and is recommended in the Dinajpur district of Bangladesh (AEZ 1) in comparison to other intercropping practices in both the cropping seasons.
Key Words: Intercrop, Sugarcane, Potato, Onion and Profitable.

Effect of different doses of urea on growth and yield performance of T. Aus rice
Abstract
This experiment was executed from April to August 2019 in the Field laboratory of Department of Agriculture at Noakhali Science & Technology University to ascertain the effect of different doses of urea fertiliser on growth and yield attributes of transplanted Aus rice. The experiment was conducted with 4 urea doses viz. 90 kg ha-1, 120 kg ha-1, 150 kg ha-1 and 180 kg ha-1 using two Aus rice varieties viz. BRRI dhan83 and BRRI dhan65. The experiment was planned with RCBD design using three replications. In between two varieties, the maximum plant length (100.08 cm), number of grains per panicle (123.86), thousand grains weight (26.33 gm), grain yield (3.86 t ha-1) and the highest harvest index (38.29 %) were obtained from BRRI dhan83 where the maximum number of tillers per hill (25.51) and the highest straw yield (6.37 t ha-1) were obtained from BRRI dhan65. BRRI dhan83 gave promising grain yield in this experiment though grain quality and price of BRRI dhan65 is better than BRRI dhan83. Among urea doses, the highest plant length (96.22 cm), total no. of tillers per hill (24.79), sterile grains per panicle (22.09), thousand grains weight (25.43 gm), straw yield (7.26 t ha-1) were found from 180 kg urea ha-1. The maximum grain yield (3.78 t ha-1) was also found from 180 kg urea ha-1 but it was found statistically identical with 150 kg urea ha-1 where the lowest grain yield (2.95 t ha-1) was observed at the minimum dose of urea (90 kg ha-1). Surprisingly the highest harvest index (37 %) was noticed in 120 kg urea ha-1. This experiment revealed that increasing dose of urea gradually increases plant vegetative growth, straw yield along with grain yield, but the application of urea above its optimum dose can cause fertiliser loss and wouldn’t give satisfactory economic return also, it may affect adversely on growth and yield attributes of rice after exceeding a critical limit. From the result, it can be said that 150 kg urea ha-1 would be the most suitable dose for T. aus rice as the desired yield obtained at a lower cost of urea.

Surprisingly the highest harvest index (37 %) was noticed in 120 kg urea ha-1. This experiment revealed that increasing dose of urea gradually increases plant vegetative growth, straw yield along with grain yield, but the application of urea above its optimum dose can cause fertiliser loss and wouldn’t give satisfactory economic return also, it may affect adversely on growth and yield attributes of rice after exceeding a critical limit. From the result, it can be said that 150 kg urea ha-1 would be the most suitable dose for T. aus rice as the desired yield obtained at a lower cost of urea.
