REVIEW ON THE EFFECT OF LEVEL OF NITROGEN ON GROWTH AND YIELD OF ONION IN ETHIOPIA | Journal of Global Agriculture and Ecology

The onion (Allium cepa L.) is a vegetable that belongs to the Alliaceae family and is the most commonly cultivated plant of the genus Allium. Onion output and productivity are governed by a number of factors. One of the factors that influences onion development is the amount of nitrogen fertiliser used. In this regard, the aim of this review paper was to examine the impact of various nitrogen levels on onion growthand yield. Onions are used for a number of medical purposes. Nitrogen is found in a variety of importantplant compounds.Nitrogen is needed for the formation of chlorophyll, proteins, and is a component of several amino acids and other molecules required for plant growth and other nitrogenous plant components such as nucleic acid and chlorophyll. Nitrogen is also needed for plant carbohydrate utilisation. In addition, results from various climatic regions around the world show that onions react differently to nitrogen application. Onion has a high nitrogen requirement, especially in the early stages of development, as increased the level of N increased the growth trend of the number of leaves, leaf length, and plant body. The use of nitrogen fertiliser increased the amount of nitrogen in the soil, according to different research findings.Onion bulb yield has also increased dramatically.

REVIEW ON WEED MANAGEMENT PRACTICES IN WHEAT (Triticum spp.) | Asian Journal of Plant and Soil Sciences

Wheat (Triticum spp.) is a cereal grain that originated in the Near East’s Levant region but is now grown all over the world. It belongs to the Plantae kingdom and the Poaceae family. Ethiopia is one of Africa’s biggest food aid recipients. Due to many production constraints, such as weed infestation, achieving the desired wheat production is difficult.  One of the main biotic constraints in wheat development is weed infestation. Wheat is infested with a variety of weed flora, both grassy and broadleaf, due to the fact that it is cultivated under a variety of agroclimatic conditions, cropping sequences, tillage, and irrigation regimes.Weedrelated yield losses differ depending on the weed type, density, and environmental factors. Weed management practises such as cultural, mechanical, biological, and chemical weed control methods can help minimise yield loss due to weed infestation. This seminar paper’s aim is to review recent research findings on wheat weed management practises. To feed an increasing population, wheat production must increase without relying heavily on chemicals such as fertilisers and herbicides, which have unpredictable negative effects on the environment and human health. For better crop yield, weed control techniques must be improved.In the agricultural sector, improved herbicide formulations with low to no toxicity except for the target weeds seem to be in high demand in the near future.

THE EFFECT OF HUMIC ACID AND HIGH POTASSIUM ON SOME GROWTH CHARACTERISTICS AND YIELD OF CAULIFLOWER | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

During the 2018-2019 planting season,the experiment was performed at the agricultural research stationto assess the effect of two levels of humic acid (1.5, 3.0) g L-1, high potassium composite fertiliser (1.5, 3.0) g L-1,and the number of treatments (twice and three times) on cauliflower growth and yield. The mediums were evaluated by least significant deference at 0.05 likelihood using a Randomized Complete Block design.The most important findings show that potassium treatment increased most indicators of vegetative development, yield, and chemistry, with 3 g.l-1 yielding the highest yield (25.45 t.ha-1).  Humic acid increased chlorophyll, the percentage ratio of dry matter in leaves and curd, and the percentage of nitrogen and potassium in leaves significantly. Curd weight, total production, carbohydrates, and potassium percentage in leaves are all affected by the amount of treatments. The relationship between the two variables resulted in a substantial improvement in all of the study’s characteristics.

Effect of Growing Degree Days on Yield Attributes and Yield of Groundnut | Current Journal of Applied Science and Technology

The objective of this study was undertaken to find out the optimum sowing window and the amount of heat units required to change their phonological development for groundnut. An field experiment was conducted at experimental farm of Agricultural College and Research Institute, Eachangkottai during Margazhi pattam 2019. The experiment was conducted in Randomized Block Design. Different morphological indices were observed (plant height, number of branches, dry matter, number of pods) and yield attributes and yield of groundnut VRI-2 was recorded. The heat unit concept of Growing Degree Days also worked out for individual sowing windows. Among the sowing dates, 05.01.2019 recorded essential GDD of 1651.3°C and higher growth attributes, yield attributes and yield (2370 kg ha-1).
