Effect of time and level of detopping on grain and fodder yield of maize (Zea mays L.)
Abstract
In a field experiment conducted during 2018-2019 at Research field, Department of Crop Physiology and Ecology, Hajee Mohammad Danesh Science and Technology University, Dinajpur the effect of detopping on grain and fodder yield of maize was studied. The single factor experiment was laid out in a randomized complete block design consisting of ten treatments viz. T0 – control (no detopping), T1 (detopping top 3 leaves), T2 (detopping top 4 leaves), T3 (detopping top 5 leaves) at 5 days after silking, T4 (detopping top 3 leaves), T5 (detopping top 4 leaves), T6 (detopping top 5 leaves) at 10 days after silking, T7 (detopping top 3 leaves), T8 (detopping top 4 leaves), T9 (detopping top 5 leaves) at 15 days after silking with three replications. The results revealed that, different stages and different levels of detopping in maize significantly influenced the growth parameters and fodder yield but the treatments did not significantly reduce grain yield compared with control. Detopping at different days after silking and different levels had no influence on first cob height, chlorophyll content, light intensity in crop canopy, canopy temperature, length of cob, girth of the cob, number of grain rows cob-1, grain number row-1, grain number cob-1, grain yield m-2, single cob weight, weight of hundred grains, grain yield, and stover yield. A significantly reduced number of leaves per plant was observed with T4 (detopping with 3 leaves at 10 days after silking) at 20 days after silking and with T1 (detopping with 3 leaves at 5 days after silking) at 30 days after silking. Leaf area was significantly reduced at T4 (detopping with 3 leaves at 10 days after silking). The highest fodder yield was obtained with T3 (detopping with 5 leaves at 5 days after silking) which was 0.783 kg fodder m-2. As no significant yield reduction was observed with various times and levels of detopping so it was concluded that maize plants can be detopped up to 5 leaves at 15 days after silking without significant reduction in yield.

Exploring Kenaf (Hibiscus cannabinus L.) seed oil: Potential edible application and nutritional benefit
Abstract
Kenaf (Hibiscus cannabinus L.) is a versatile plant belonging to the Malvaceae family. Historically valued for its fiber, Kenaf has gained attention for its nutritional and medicinal properties. The study aimed to analyze the nutritional composition of Kenaf seed oil and to assess edible application of Kenaf seed oil. Addressing the study objectives, the study was conducted at three different laboratories from February 2024 to May 2024. Potential Edible Application and Nutritional Benefits from kenaf seed oil were analyzed by considering essential fatty acid, specific gravity, and total tocopherol. There were 9 essential fatty acids found like C14:0 (Myristic acid) 0.15%; C16:0 (Palmitic acid) 20.29%, C16:1 (Palmitoleic acid) 0.61%, C17:0 (Heptadecanoic acid) 0.06%, C18:0 (Stearic acid) 1.40%, C18:1 (Oleic acid) 27.44%, C18:2 (Linoleic acid) 49.43%, a polyunsaturated fatty acid C18:3 (Linolenic acid) 0.47% and C24:0 (lignoceric acid) 0.14%. The specific gravity of the sample at 30°C was 0.9124 g/ml. Vitamin E which were found as Alpha Tocopherol (43 mg/100g), Gamma Tocopherol (31.23 mg/100g) and Delta Tocopherol (2.83 mg/100g). These nutritional and functional properties of the kenaf will be helpful for further research, development and application in various industries in connection to food, cosmetics, pharmaceuticals and health issues.

Effect of biochar on growth and yield of cabbage (Brassica oleracea var. capitata L.) in coastal region
Abstract
The process of heating biomass (wood, manure, crop residues, solid refuse, etc.) with little to no oxygen in a furnace that has been specifically designed to capture all emissions, gases, and oils for later use as energy results in biochar, which is fine-grained charcoal. The capacity of biochar to draw in and hold water, nutrients, phosphorus, and agrochemicals is superior to that of any other organic soil material. Less fertilizer leaches into groundwater and flows off into surface waters, and plants are healthier as a result. The head of cabbage (Brassica oleracea var. capitata) is a small, leafy biennial that produces a tightly packed globular mass of smooth or crinkled leaves coiled around one another. The cultivation of cabbage benefits greatly from the use of biochar. Using biochar reduces the cost to the farmer because it eliminates the need for water irrigation and chemical fertilizer. The experiment was conducted to evaluate the effect of biochar on growth and yield of cabbage (Brassica oleracia var. capitata) at the Research Field of the Department of Agriculture, Noakhali Science and Technology University (NSTU), Sonapur, Noakhali-3814. The biochar was added to the soil at 0, 3.0, 6.0, 9.0 and 12.0 tons per hectare, respectively. The treatments were arranged in a Randomized Complete Block Design with 3 replications from mid-January 2022 to mid-April 2022. Significant variations (p < 0.01) for all the parameters were revealed in the study. According to the study, the highest plant height was (19.92 cm), leaf length (26.12 cm), leaf breadth (23.14 cm), number of unfolded leaf (19.12 cm), weight of largest leaf (34.00 g), head diameter (15.14 cm), head width (13.00 cm), weight of head (765 g), dry weight of head (91.30 g), stump length (10.24 cm), stump diameter (2.20 cm), root length (21.00 cm) and chlorophyll content (73.00). The result indicates the good performance of wood biochar in cabbage production. The maximum growth and yield of cabbage come from T5 (12.0 t ha-1). The experiment suggested that T5 (12.0 t ha-1) is the best for improvement in mostly edible cabbage crops during winter season in Bangladesh.

Seasonal incidence and management of major insect pests infesting maize and its correlation with weather factors
Abstract
In terms of food and feed value, maize (Zea mays) has become the most significant cereal crop in Bangladesh after rice. The research was carried out to study the seasonal incidence of aphid (Rhopalosiphum maidis), stem borer (Sesamia inferens), and corn borer (Ostrinia nubilalis) and their correlation with the weather factors during 2022-2023 at the Entomology Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh. Three replications of this experiment were carried out using a Randomized Complete Block Design (RCBD). Three-unit plots were used for the study of insect-pests incidence. In the case of pest management, three botanicals, namely leaf extract of neem (3.ml/L) & bishkathali (3.ml/L) and clove extract of garlic (3.ml/L), were used as an experimental treatment for controlling the tested pests. The seasonal incidence studies indicated that three insect pests, viz., maize aphid, stem borer, and corn borer were observed as the major insect pests on maize. All pests had a negative correlation with temperature, relative humidity, and rainfall. But considering the plant infestation and damage severity, the maize aphid was the major insect of maize, which caused about 81.34 percent of plant infestation. Among tested botanicals, neem leaf extract @ 3.0ml/L showed the best performance for controlling all tested pests and returned a higher yield compared to garlic clove and bishkathali leaf extract. Therefore, it is possible to conclude that the findings of this study may aid the implementation of appropriate pest control measures by identifying the vulnerable stages of these pests, minimizing the frequent application of toxic pesticides, and providing opportunities to grow in a less hazardous environment. Moreover, neem leaf extract @ 3.0ml/L is the best botanical to control the tested pest and return a higher yield.

Impact of organic leachate on growth and yield of ornamental sunflower
Abstract
A field experiment was accomplished at the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, from October to December 2021 to evaluate the impact of organic leachate on the growth and yield of ornamental sunflower. The variety used was "Hybrid Ornamental Sunflower (F1)" (Vincent Choice). The single-factor experiment was laid out in a randomized complete block design (RCBD) with three replications. The experiment consisted of four treatments namely, T: Control (no leachate application), V: Vermicompost leachate, N: Neem oil cake leachate and M: Mustard oil cake leachate. Data on different growth, flower yield and quality attribute parameters were taken and all the treatments showed significant variations. Among the treatments, the tallest plant height (120.1 cm), the maximum number of leaves (35.1), leaf area (158.9 cm2), SPAD value (34.7), stalk diameter (7.1 mm), ray floret area (27.9 cm2), flower head size (15.0 cm), and flower head weight (30.4 g) showed superiority in N (Neem oil cake leachate). On the contrary, the shortest plant height (94.1 cm), the minimum number of leaves (28.1), leaf area (100.3 cm2), SPAD value (31.6), stalk diameter (5.3 mm), ray floret area (15.6 cm2), flower head size (10.8 cm), and flower head weight (16.9 g) observed minimum in T (Control) treatment. As a result, it can be concluded that N (Neem oil cake leachate) is an easy and effective organic substance that can potentially increase the entire growth and yield of ornamental sunflowers to advance the commercial cut-flower industry in Bangladesh.
Key Words: Organic matter, Cut flower and Safe production.
