A field experiment was carried out to study the effects of inorganic nitrogenous fertilizer and organic cowdung manure on growth and yield of carrot. Three different levels of urea along with three different levels of cowdung were employed in the investigation following randomized complete block design. The result revealed that the application of 150 kg N ha-1 as urea was found suitable for maximum gross and marketable yield (47.35 t ha-1 and 39.0 t ha-1, respectively), while 15 t cowdung ha-1 showed better gross and marketable yield (38.13 t ha-1 and 30.42 t ha-1 , respectively). Regarding the combined effect, the combination of 150 kg N ha-1 and 15 t cowdung ha-1 resulted in the best performance in gross and marketable yields (51.22 t ha-1 and 43.41 t ha-1, respectively). The net return (TK. 211142 ha-1) and benefit cost ratio (4.61) were maximum in the treatment combination of 150 kg N ha-1 in the form of urea and 15 t cowdung ha-1.DOI: http://dx.doi.org/10.3329/jbau.v10i1.12012J.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

AbstractA field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea var. gongylodes) at Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna from November 2014 to February 2015. The single factor experiment comprised of different types of fertilizers and manures viz., T0 (Control), T1 (Recommended doses of NPK), T2 (Cow dung), T3 (Vermicompost), T4 (Poultry manure), T5 (50 % Cow dung + 50 % NPK), T6 (50% Vermicompost + 50% Cow dung), T7 (50% Vermicompost + 50 % Poultry manure) and T8 (25% Cow dung+ 25% Vermicompost+ 25% Poultry manure + 25% NPK). The Experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The maximum plant height was obtained from the treatment T1 at 25, 35 and 45 Days after transplanting (DAT). The maximum spread of canopy was 36.75 cm, 52.50 cm and 66.05 cm from the treatment T3, T7 and T2, respectively. The maximum economic yield (21.92 t/ha) and biological yield (40.083 t/ha) were found in the treatment T1 and T7, respectively. Highest benefit cost ratio (3.07) was obtained from the treatment T1whilethe minimum (0.57) was obtained from T3 which indicates that high cost of vermicompost affect net return severely. Although, T1 produced maximum benefit cost ratio, the treatment T4 and T2 are very close to T1 and also statistically similar. So, we can consider poultry manure and cow dung for our soil health, environmental benefits and ecological safety.

A field trial on soil test based (STB) fertilizer doses was conducted during the year of 2017-2018 and 2018-2019 in Jashore region (AEZ-11) to find out the most suitable fertilizer doses for four crop based cropping pattern considering the agronomic feasibility and economic return of the system. The experiment consisted of eight different treatments viz. T1: 100% NPKSZnB (STB), T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5:T1 + 25% PK, T6:T1 + 25% NPK, T7: 75% of T1, T8: Native fertility. Randomized complete block design (RCBD) with three replications was followed. Data revealed that seed yield of mustard was remarkably influenced by fertilizer treatments while grain yield of other components of the cropping system was not affected significantly by the treatments except control or native fertility. It was observed that 25% more NPK over 100% STB dose provided the highest yield of all the component crops. The highest rice equivalent yield (3.34 t ha-1) was recorded from T6 and the lowest (1.88 t ha-1) from T8 treatment. Maximum gross return (Tk. 420000/ha) and marginal benefit cost ratio (4.08) were also obtained from T6 treatment. So, 25% NPK+ 100% STB dose of fertilizer could be followed for productive and remunerative rice based cropping system Mustard-Boro-T. Aus-T.Aman in AEZ-11. Bangladesh Agron. J. 2021, 24(1): 109-117

Background: Groundnut is one of the most important oilseed crops of Odisha and grown in both in kharif and rabi-summer seasons. Because of excessive vegetative growth in kharif season, the yield potential is lower than rabi-summer resulting in low yield. Keeping this in view, an experiment was set up to investigate the effect of different concentration and time of paclobutrazol application on growth and yield of groundnut.Methods: A field experiment was conducted during kharif 2016 to 2018 at AICRP on Groundnut Research Farm, OUAT, Bhubaneswar, Odisha. The experiment was laid out in split plot design with different concentration of paclobutrazol in main plot and time of application in sub plot and replicated thrice. Recommended dose of 20:40:40 kg of N, P2O5 and K2O entirely applied as basal. Yield and yield attributing characters were taken at the time of harvest.Conclusion: Application of paclobutrazol at different concentration significantly reduced groundnut plant height and significant reduction was observed with application at 30 DAE. Among various yield attributing characters; pod/plant and pod yield increased significantly (24.6% and 27.4%, respectively) with application of paclobutrazol @ 100 ppm with higher benefit cost ratio of 1.97 and upto (8.4% and 17.5%) with application at 30 DAE.
