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.
