Experiments were carried out at the research field of Horticulture Research Centre, BARI, Joydebpur during kharif seasons of 2010 and 2011 to find out the requirement of N, P, K, and S application for obtaining higher yield of bitter gourd (var. BARI Karola-1). There were 14 treatment combinations comprising four levels each of N (0, 90, 20,150 kg/ha), P (0, 20, 40, 60 kg/ha), K (0, 40, 80, 120 kg/ha), and S (0, 20, 30, 40 kg/ha). A blanket dose of 2 kg B, 4 kg Zn, and 5 ton cowdung/ha was used. The maximum fruits/plant, fruit size, and single fruit weight and yield of bitter gourd was achieved from the treatment N120 P40 K80 S30 kg/ha and the lowest from the control treatment. The yield benefit for the best treatment over the control was 208% in 2010 and 137% in 2011. Response to N and P was more pronounced in comparison to K and S. The yield increased linearly with increasing rates of N up to 120 kg/ha, P up to 40 kg/ha, K up to 80 kg/ha, and S up to 30 kg/ha and thereafter decreased. The highest gross margin (Tk. 486867/ha) and marginal rate of return (8083%) was also obtained from the same treatment. Overall results reveal that application of N120 P40 K80 S30 kg/ha along with a blanket dose of 2 kg B, 4 kg Zn and 5 ton cowdung/ha appears to be the best treatment for maximizing the yield of bitter gourd in Grey Terrace Soil (AEZ-28) of Joydebpur.

The experiment was conducted at the research field of Regional Horticulture Research Station, Chapai Nawabganj during 2010-11, 2011-12 and 2012-13 to find out the proper combination of fertilizer nutrients (N, P, K and S) in presence of organic manure for obtaining higher yield of mango (var. BARI Aam-1). The treatments were native nutrient i.e. control (T1), N360P80K150S50 (T2), N560P120K200S70 (T3), N760P160K250S90 (T4), N960P200K300S110 (T5), and N1100P300K500S120 i.e. farmers practice (T6) g/tree/year. In addition, 20 kg cowdung/tree was used as blanket dose. Number of fruits/tree, individual fruit weight, fruit size, stone weight, peel weight, TSS content and yield of mango varied significantly due to variations of nutrients in all the years. The highest yield and yield attributes were recorded under treatment N960P200K300S110 g/tree and it was statistically identical with N760P160K250S90 g/tree. The lowest yield was obtained from untreated control plot (native nutrient). The yield benefit for the best treatment (T5) over the control was 86% in 2010-11, 64% in 2011-12 and 73% in 2012-13. The highest gross margin (Tk 2509/tree in 2010-11, Tk 2651/tree in 2011-12 and Tk 2478/tree in 2012-13) and marginal rate of return (2375% in 2010-11, 2225% in 2011-12 and 2300% in 2012-13) was also obtained from the same treatment. Three years’ study revealed that application of N960P200K300S110 g/tree along with a blanket dose of 20 kg cowdung/tree appears to be the best treatment and economically optimum for achieving higher yield of mango in Chapai Nawabganj region.

Strawberry (Fragaria X annanassa Duch.) is highly exhaustive and responsive to chemical fertilizers. An experiment on strawberry was conducted in fruits research field of Horticulture Research Centre, BARI, Gazipur over three consecutive years, 2009-2010, 2010-2011 and 2011-2012 to find out the suitable combination of nitrogen (N), phosphorus (P), potassium (K) and sulphur (S) for yield maximization of strawberry. Fourteen treatment combinations were tested in this trial comprising four levels each of N (0, 90, 115 and 140 kg ha-1), P (0, 20, 40 and 60 kg ha-1), K (0, 85, 110 and 135 kg ha-1) and S (0, 15, 25 and 35 kg ha-1) with blanket dose of 4 kg Zn ha-1, 2 kg B ha-1 and 10 t cowdung ha-1. The experiment was set up in randomized completely block design with three replications. Results showed that treatment combination N115P40K110S25 (underscript represent kg ha-1) produced higher strawberry fruit yield (9.59 t ha-1) followed by N90P40K110S25 kg ha-1 and N140P40K110S25 kg ha-1 treatment combinations. The lowest fruit yield (6.05 t ha-1) was found in control (N0P0K0S0) treatment. Therefore, the combination of N115P40K110S25 kg ha-1 may be considered as suitable dose for strawberry cultivation in terrace soils of Bangladesh.Bangladesh J. Agril. Res. 43(1): 89-97, March 2018

A field experiment was conducted at vegetables research field of Horticulture Research Centre, Gazipur in terrace soils under Madhupur Tract (AEZ 28) during rabi seasons of 2009-10, 2010-11and 2011-12 to determine the optimum dose of boron and zinc for yield maximization of capsicum. There were sixteen treatment combinations comprising four levels each of B (0, 1, 2 and 3 kg ha-1) and Zn (0, 2, 3 and 4 kg ha-1) along with blanket dose of N150P65K120S20 kg ha-1 including cow dung 10 t ha-1 were used. The experiment was laid out in RCBD factorial with three replications. Results revealed that maximum mean number of fruits per plant (11.1), the highest fruit length (9.29 cm) and diameter (7.34 cm), maximum individual weight of fruits (122 g) were recorded from the combination treatment of B2.0Zn3.0 and the highest mean yield (31.8 t ha-1) was also recorded from the same treatment. The 84.8% yield increase over control (B0Zn0) due to combined application of B2.0Zn3.0 kg ha-1. The combined application of zinc and boron were observed superior to their single application. Therefore, the combination of B2.0Zn3.0 treatment may be considered as suitable dose for capsicum cultivation in terrace soils of Bangladesh.Bangladesh J. Agril. Res. 42(1): 43-52, March 2017

In various orchard fruit trees, thinning of blossoms and fruits is important to increase fruit size and quality and to promote a new bloom in the following season. Several chemical thinning agents are currently commercially available, but they are inconsistent and produce side effects in crop plants and insect pollinators. Because of environmental concerns, developing alternative eco-friendly bloom thinning agents is necessary. We developed an eco-friendly bloom thinning formulation (BTF) using minerals and extracts of various medicinal plants. Our BTF spray (0.1%, <i>w/v</i>) decreased the number of fruits per tree (46.5%) and fruit yield per tree (81.5%) but increased the fruit weight (196.8%) compared with the control treatment; the spray induced a small number of larger mango fruits in the treated trees. We also investigated the effect of BTF on the olfactory behavior of <i>Apis mellifera</i> L. (Hymenoptera, Apidae), a major insect pollinator. We analyzed the behavioral changes of adult workers at two different concentrations (0.1% and 1%) of nine different BTF spray components using a Y-tube olfactometer. The behavioral responses of honey bees to nine BTF components showed significant differences. However, honey bees showed no clear attraction or repellent behavior towards the tested BTF components. Our results suggest that the newly developed eco-friendly BTF is practically applicable in mango orchards without interrupting honey bee behavior.

An investigation was undertaken with a view to observing the performance of newly developed summer tomato hybrids during May 2008 to September 2008 at experimental field of Horticulture Research Centre, BARI, Gazipur. Number of fruits per plant, individual fruit weight, fruit size, etc. was significantly higher when the plants were treated with hormone. Fruit yield per plant was quite high in the hormone treated plant (1.57 kg) compared to untreated plants (0.90 kg). In general, all the hybrids performed better when treated with hormone in respect of yield compared to their corresponding untreated plants. The hybrid WP7 × C- 51 had the highest individual fruit weight (56.0 g) Among the hybrids, HT019 × WP10 had the highest fruit yield per plant (1.87 kg) closely followed by C-11 × WP10 (1.81 kg) when the plants were treated with hormone. The untreated plants of the hybrid lines C-41 × WP8, HT019 × WP10 and C-41 × WP10 produced more than 1.0 kg of fruits per plant. This indicates that there is bright scope of tomato production during summer through with and without hormone application, though application of hormone had positive effect on tomato yield.

A field experiment was carried out during two consecutive cropping seasons of 2001-02 and 2002-03 at the Agricultural Research Station, Raikhali, Rangamati, to optimize fertilizer need for desirable yield of Panchamukhi Kachu (Colocasia esculenta var. esculenta Schott.). Fourteen combinations of treatments consisting four levels of N (0, 50, 100 and 150 kg/ha), five levels of P2O5 (0, 25, 50, 75 and 100 kg/ha), four levels of K2O (0, 60, 120 and 180 kg/ha) and three levels of cowdung (0, 10, 20 and 30 t/ha) were tested. A positive impact of each nutrient and cowdung application was observed on vegetative growth and fresh yield of the crop. The highest yield (average of two years) of 35.20 t/ha (54% increase over control) was obtained with the application of 100 kg of N, 75kg P2O5, 180 kg, K2O and 10t cowdung/ha. From the economic point of view, the combination of 100 kg of N, 75kg P2O5, 180 kg K2O and 10 ton cowdung/ha was found to be the most suitable one which offered a gross return and gross margin of TK. 3.25 lakh/ha and Tk. 3.39 lakh/ha, respectively coupled with marginal rate of return as high as 3530.77%.

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

The field experiment was conducted during the rabi season of 2005-06 in the farmer's field of Multi-location Testing (MLT) site, Melandah, Jamalpur to evaluate the performance of sweet potato varieties as well as to determine the optimum dose of fertilizer of sweet potato. Two varieties of sweet potato viz., i) BARI Sweet Potato-5 and ii) BARI Sweet Potato-7 and five fertilizer doses viz., i) Estimated fertilizer dose for average yield goal (EDI for average yield goal), ii) Integrated Plant Nutrient System (IPNS) basis fertilizer dose, iii) Fertilizer Recommendation Guide' 97, iv) Farmer's practice, and v) Control. The highest sweet potato yield was obtained from BARI SP-7 with (IPNS) basis fertilizer doses (33.9 t/ha). The lowest sweet potato yield was obtained from BARI SP-7 with control treatment. The highest gross return (112700 Tk./ha) and gross margin (10756 Tk./ha) was recorded from IPNS basis fertilizer treatment. The lowest gross return (40950 Tk./ha) and gross margin (40951) Tk./ha) was recorded from control treatment. But the cost and return analysis showed that the highest benefit cost ratio (24.95) and marginal rate of return (1452) was found from FRG/97 treatment due to lower additional cost.

The objective of the experiment was to investigate the influence of organic (poultry) manure, inorganic manure (N.P.K) and their combination on the growth and yield of sweet pepper in the transitional zone of Ghana. The experiment was conducted at the research field of the College of Agriculture Education, University of Education Winneba, Mampong campus in 2017. The experiment was laid out in randomized complete block design (RCBD) which consisted of four treatments with 4 replications. The treatment groups were: Control (no soil amendment), 10 t/ha PM, 300 kg/ha N.P.K, and 5 t/ha PM + 150 kg/ha N.P.K. All the treatments were given fair and equal attention in terms of watering, weeding and disease and pest control. The result showed that 10 t/ha PM recorded (P=.05) the tallest plant height, greater number of leaves and leaf area per plant, days taken for 50% bud appearance and flowering, the highest number of flowers per plant and the minimum days to fruit set, highest number of fruit set minimum days to harvesting with the control been the least in all traits. Similarly, 10 t/ha PM recorded (P=.05) had the highest number of fruits per plant, average fruit weight and fruit yield while the control treatment recorded the least in all traits. This study concludes that the application of poultry manure improves the productivity of sweet pepper. This study recommends that 10 t/ha PM is an ideal for maximum vegetative growth and yield of sweet pepper.
