A field experiment was conducted at Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat during Rabi seasons of 2016-17 and 2017-18 to study the response of niger to different levels of nitrogen, phosphorus and potassium as well as sulphur on growth, yield and oil content of niger. The experiment was laid out in Factorial Randomized Block Design with three replications. The treatments comprised of three NPK levels viz., F1 (20-10-10 kg N-P2O5-K2O ha-1), F2 (25-12.5- 12.5 kg N-P2O5-K2O ha-1), F3 (30-15-15 kg N-P2O5-K2O ha-1) and three S levels viz., S1 (no sulphur), S2 (10 kg S ha-1), S3 (20 kg S ha-1). Application of F3 (30-15-15 kg N-P2O5-K2O ha-1) and S3 (20 kg S ha-1) recorded maximum and significantly higher seed yield (q ha-1), oil content (%), oil yield (q ha-1) as well as growth and yield attributing parameters viz., plant height, number of leaves plant-1, number of branches plant-1, number of capitulum plant-1 and number of seeds capitulum-1 during both the years. Test weight was not influenced significantly during both the years. Interaction effects of NPK (F) and sulphur (S) were found to be not significant in respect of growth and yield attributing characters in both the years. In case of seed yield (q ha-1) and oil yield (q ha-1) interaction effect were found to be significant in both the years.The highest gross return (Rs. 23,905.00 in 2016-17 and Rs. 22,400.00 in 2017-18) and net return (Rs. 11,184.86 in 2016-17 and Rs. 9679.86 in 2017-18) were recorded by F3S3 in both the years. In case of benefit-cost ratio, the higher value (1.88 and 1.76, respectively) was recorded with F3S3 during 2016-17 and 2017-18.

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.

A field experiment was conducted at the Horticultural Farm of Sher-e–Bangla Agricultural University, Dhaka from October, 2017 to March, 2018 to study the effect of micronutrients in presence of different level of organic manure on growth and yield of tomato. There were four combinations of micronutrients viz. N0=0 kg Zn 0 kg B/ha, N1= Zn2 kg B1.5 kg/ha, N2=Zn4 kg B2 kg/ha, N3=Zn6kg B2.5 kg/ha and four organic manure viz M0=0 ton/ha, M1=Cowdung (15 ton/ha), M2=Poultry manure (10 ton/ha), M3=(Cowdung 7.5 ton/ha+ Poultry manure 5 ton/ha). The experiment was laid out in a Randomized Complete Block Design with 3 replications and there were altogether 48 plots. Application of micronutrients and organic manure significantly influenced the growth, yield and size of the tomato. The highest yield (66.96 t/ha) was found from treatments N2 and the lowest yield (25.69 t/ha) was obtained from treatment N0. Due to the application of organic manure, the highest yield (50.78 t/ha) was obtained from M3 and the lowest yield (39.86 t/ha) was recorded from M0. In the case of combined effect, the highest yield (76.33 t/ha) was found from treatment N2M3 and the lowest yield (24.60 t/ha) was found from treatment N0M0. So, the application of Zn4 kg B2 kg/ha along with Cowdung 7.5 ton+Poultry manure 5 ton/ha was the best for growth and yield of tomato. Economic analysis raveled that N2M3 gave the maximum benefit-cost ratio (3.2). So, the application of Zn4 kg B2 kg/ha along with Cowdung 7.5 ton+Poultry manure 5 ton/ha was the best for growth and yield of tomato.

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.

A field experiment was conducted in humid sub-tropics of West Bengal at the Instructional Farm, Jaguli of Bidhan Chandra Krishi Viswavidyalaya (BCKV), Nadia, India during 2016-17 to study some growth and yield parameters, also the economic advantages of various weed management treatments of summer transplanted paddy. The experiment was conducted with 8 treatments [T1- & T2 - Pre–emergence (PE) sole aqueous organic botanical extracts (AOBE) of Tectona grandis & Bambusa vulgaris respectively @ 100 mL/L water; T3 - PE sole synthetic organic chemical herbicides (SOCH) Pretilachlor 30.7 EC @ 500 g/ha;T4 – PE mixture of AOBE of Bambusa vulgaris & Tectona grandis @ 100 mL/L water; T5 – PE mixture of AOBE of Tectona grandis @ 100 mL/L water & SOCH Pretilachlor 30.7 EC @ 500 g/ha; T6 -PE mixture of AOBE Bambusa vulgaris of @ 100 mL/L water & SOCH Pretilachlor 30.7 EC @ 500 g/ha; T7 – Hand weeding (HW) at 25 & 45 days after transplanting (DAT) and T8 – Weedy check with three replications following randomised block design (RBD). The results revealed that the treatments T7 recorded the maximum biological yield (grain – 4.76 & straw 5.95 t/ha) and was statistically at par with the mixture of botanical and chemical treatments (T5 - 4.35 and 5.52 t/ha respectively) and T6 - 4.42 and 5.54 t/ha, respectively). The T6 recorded the highest benefit – cost ratio (BCR) value of 2.41 followed by T5 with 2.38. But in case of treatment T7, maximum cost of cultivation was incurred over all treatments due to higher expenditure on labour wages for that reason BCR was comparatively lower (2.02) and the lowest BCR was obtained against weedy check (T8) 1.85. Therefore, considering the crop growth, rice productivity, economics and farmers‟ easy availability the mixture treatments of AOBE Bamboosa vulgaris or Tectona grandis with SOCH Pretilachlor may be the best option and is an alternative to traditional HW treatment for increasing rice productivity through ecosafe weed management in transplanted paddy.

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.

Sowing Dates

The sowing date is an important factor for expanding the cultivated area of rapeseed and affects seed yield, oil content, and fatty acid compounds. Micronutrient elements play an important role in improving the vegetative and reproductive growth of the plant, especially under conditions of biological and environmental stresses. A two-year experiment (2014-2016) was performed to study the response of rapeseed genotypes to foliar application of micronutrients on different sowing dates. The treatments were arranged as a factorial-split plot in a randomized complete block design with three replicates. Three sowing dates of 7 (well-timed sowing date), 17, and 27 (delayed sowing dates) October and two levels of foliar application with pure water (control), selenium (1.5%), zinc (1.5%), and selenium+zinc (1.5%) were factorial in the main plots and five genotypes of SW102, Ahmadi, GKH2624, GK-Gabriella, and Okapi were randomized in the subplots (a total of 30 treatments). Seed yield, oil yield and content, oleic acid, and linoleic acid were reduced when rapeseeds were cultivated on 17 and 27 October, while the contents in palmitic, linolenic, and erucic acids, and glucosinolate increased (p < 0.01). a selenium+zinc treatment improved seed yield, oil content and yield (p < 0.01). The oil quality increased due to increased contents of oleic and linoleic acids under the selenium+zinc treatment (p < 0.01). The GK-Gabriella and GKH2624 genotypes are recommended to be sown on well-timed (7 October) and delayed sowing dates (17 and 27 October) and treated with selenium+zinc due to the higher oil yield, linoleic and oleic acids.
