A study was conducted at central farm of Sher-e-Bangla Agricultural university, Dhaka during the period of October, 2017 to March, 2018 to investigate the influence of starter solution and age of seedling on the growth and yield of broccoli. The experiment consisted of two factors. Factor A: Four levels of starter solution as S0= 0% urea solution (control), S1= 1% urea solution, S2= 2% urea solution, S3= 3% urea solution and Factor B: Three levels of age of seedling as A1= 20 days of seedling, A2= 30 days of seedling, A3= 40 days of seedling. Application of the treatment influenced independently and also in combination on the growth and yield of broccoli. In case of starter solution, the highest yield (24.32 t/ha) was obtained from S2 (2% urea) treatment, whereas the lowest yield (13.21 t/ha) was recorded from S0 (0% urea) treatment. For three level of age of seedling the highest yield (20.75 t/ha) was obtained from A2 (30 days old seedling) treatment and the lowest yield (15.48 t/ha) was recorded from A3 (40 days old seedling) treatment. In case of combined effect the highest yield (26.91 t/ha) of broccoli was obtained from the treatment combination of S2A2 while the lowest (13.41 t/ha) was obtained from S0A3 treatment combination. Economic analysis revealed that S2A2 treatment combination was the best in respect of net return (3,24,890 tk) with benefit cost ratio of  2.5. So it may be concluded that 2% starter solution and 30 days age seedling was best for growth and yield of broccoli.

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.

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.

Banana (Musa spp.) is a vigorously growing, monocotyledonous herbaceous plant. Though Bangladesh is more suitable for production of banana but its productivity is very low due to a lack of improve variety, sustainable production & protection technology, soil fertility and fertilizer management. Fertilizers i.e. nitrogen and potassium are one of the most important elements that can play vital role to increase productivity of banana. Hence, the present research investigation was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during the period from November, 2016 to December, 2017 to evaluate the effect of nitrogen & potassium fertilizers on growth and yield and also find out the best combination of N & K fertilizers for economic production of banana. Four levels of Nitrogen (N1=300g Urea/plant, N2=400g Urea/plant, N3=500g Urea/plant and N4=600g Urea/plant) and four potassium (K1=250g MOP/plant, K2=350g MOP/plant, K3=450g MOP/plant, K4=550g MOP/plant) were studied in a randomized complete block design (RCBD) with three replications. The results revealed that the single application of N3=500g Urea/plant, K3=450g MOP/plant and their combination (N3×K3=500g urea/plant×450g MOP/plant) showed more significant increase in morpho-physiological characteristics namely pseudo-stem height (m), pseudo-stem girth (cm), number of functional leaves, total number of leaves per plant, minimum days to bunch maturity & crop duration (days) and increase in yield contributing characters viz. total number of fingers per bunch, total number of hands per bunch, bunch weight (kg/plant), yield (t/ha) and benefit cost ratio in this study. The application of these two fertilizers as single or their interaction would be the most appropriate level for getting the superior growth and yield performance of banana.

Modern agriculture requires a modern approach which responds to the necessity of mankind. The study presents the fabrication and performance evaluation of a cassava grater with  juice extractor. Such performance evaluation was conducted to determine its grating and juice extracting capacity and efficiency. It was made from locally available materials then tested experimentally using cassava with a grating capacity of 160 kg/hr. The study employed the Complete Randomized Experimental Design (CRD). In evaluating the experiment, the Two-way Analysis of Variance (ANOVA) was used to determine the significant effect of each factor and the Tukey’s test was used to determine the significant difference between the combined treatments. Two factors with different levels were treated upon the experiment.  These were mainly soaking time (0 min, 5 min, 10 min, 15 min) and the way the cassava was grated and juice extracted (Machine, Manual).  Among these treatment combinations, the soaking time of 15 minutes obtained the highest grating and extracting capacity as well as for the grating and extracting efficiency leaving its quality and acceptable appearance on top.  The computed benefit-cost ratio of 1.86 showed that grating and extracting cassava juice using the cassava grater with juice extractor was highly profitable and economical for local cassava producers.

The objective of this study was to verify levels of shade and doses of earthworm humus in the production of Lactuca canadensis L. seedlings.  The experimental design was completely randomized in a 4 x 5 factorial scheme (four levels of shade and five doses of humus).  The different levels were obtained using black polyethylene screen with 35, 50 and 70% shade and in full sun. The substrates were obtained by mixing commercial substrate for vegetables (Vivatto Slim ® plus), with earthworm humus in the proportions of 0, 15, 30, 45 and 60%.  There was no seedlings emergence in the full sun and, the treatment with 50% of shade allows the best development. The substrate without humus and with 60% presented superior results but the higher dose stood out for number of leaves (3.14) and chlorophyll content (32.9%), in 50% of shade. For the other variables, there was no difference between the commercial substrate and 60% of humus, so the commercial substrate can be used in the production of Lactuca canadensis L. seedlings, considering the ratio benefit/cost ratio.

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.

An experiment was conducted at the research field of Horticulture Research Centre, BARI, Gazipur during Rabi season of 2012-13 to 2014-15 to evaluate the response of different doses of N, P and K on the yield and yield attributes of chrysanthemum (var. BARI Chrysanthemum-1) and to find out the optimum and economic doses of NPK for maximizing yield of chrysanthemum. Treatments comprising four levels each of N (0, 100, 150 and 200 kg ha-1), P (0, 50, 75 and 100 kg ha-1) and K (0, 90, 135 and 180 kg ha-1) along with blanket dose of 2 kg B and 4 kg Zn ha-1 were used. The treatments were assigned in a randomized complete block design with three replications. The combined effect of NPK significantly increased yield and yield attributes of chrysanthemum for each of the yearly experiments as well as the average of three years results. Significantly, the highest flower yield (12.45, 11.47 and 11.96 t/ha) was obtained with the application of N150P75K135 kg ha-1 (T3) along with blanket dose of 2 kg B and 4 kg Zn ha-1 for the years of 2012-13, 2013-14 and 2014-15, respectively and it was statistically identical with T4 (N200P75K135 kg ha-1) treatment. Application of 150 kg N, 75 kg P and 135 kg K increased yield by 52.76, 42.29 and 36.51%, 152.08, 126.23 and 99.13% and 88.35, 51.30 and 60.75%, respectively, over their control in respect to the years. The highest benefit-cost ratio 5.54 followed by 5.14 was obtained from T3 (N150P75K135 kg ha-1) followed by T4 treatment, respectively. From the quadratic regression equation averaging three years data the optimum and economic doses 155 and 151.8 kg N, 79.3 and 77.68 kg P and 118.75 and 115.7 kg K, respectively were found which could be recommended for chrysanthemum production in Grey Terrace Soil of Joydebpur under AEZ 28.The Agriculturists 2017; 15(1) 58-67

This research was aimed at evaluating the effect of mixing substrates on the growth and yield of Oyster mushrooms (Pleurotus ostreatus). Seven substrates, namely, Trt1 (cotton waste), Trt2 (wheat straw), Trt3 (crushed baobab fruit shells, 100%), Trt4 (cotton husk + wheat straw + crushed baobab fruit shells, 1 : 1 : 1), Trt5 (baobab fruit shells + cotton husks, 1 : 1), Trt6 (baobab fruit shells + wheat straw, 1 : 1), and Trt7 (cotton waste + wheat straw, 1 : 1) were used. Each treatment was replicated 5 times and laid out in a CRD. The duration of developmental stages, yield, and biological efficiency was recorded. Cotton waste demonstrated a significantly ( p < 0.05 ) higher mycelial colonization rate taking an average of 18.20 days to complete full spawn run, 23.20 days from spawning to pinhead formation, 2.80 days for pins to mature, and an average of 26.00 days to first harvest. There was a significant ( p < 0.05 ) difference in the total number of pins with cotton waste being the highest with an average of 29.80 pins, although it was not significantly different from Trt4. The highest (5.40 cm) stipe girth was recorded from Trt4 while the highest (5.22 cm) cap diameter was recorded in Trt1. There was a significant ( p < 0.05 ) difference in yield and biological efficiency. Trt1 had the highest (1.292 kg) average yield; however, it was not significantly ( p > 0.05 ) different from that of Trt4 (1.289 kg). From the research, it was observed that mixing substrate can help to increase yield and, as a result, a higher benefit-cost ratio. Therefore, further studies should be done to evaluate the effects of mixing other substrates besides the ones used in this current research.
