Growth and Yield Performance of Vegetatively Propagated Guinea Grass (Panicum maximum L) | Chapter 3 | Research Advances and Challenges in Agricultural Sciences Vol. 3

An experiment on the growth and yield performance of vegetatively propagated Guinea Grass using five plant densities and different levels of Nitrogen fertilizer application was conducted at the Teaching and Research Farm University of Nigerian Nsuka. The treatment consisted of five plant densities (10,000, 20,000, 40,000, 80,000 and 100,000 stands/ha) and two levels of Nitrogen fertilizer application (75kg N/ha, 150 kg N/ha) and a control without Nitrogen fertilizer application were combined in a split plot arrangement with Nitrogen fertilizer allotted the main plot and spacing the Subplots in a Randomized Complete Block Design (RCBD) replicated three times. Parameters evaluated were plant height, leaf area, tiller number, leaf number, at bi-weekly interval for eight weeks, while leaf and tiller dry weight were determined after fodder harvest. Results showed that Nitrogen application had no significant effect on plant height, leaf area, tiller number, leaf number, leaf and tiller dry weight. Spacing however, produced significant effect on plant height, filler number, leaf number, leaf and tiller dry weight. Plant population of about 80,000 and 100,000 clumps/ha produced substantial reduction of weeds.

Determination of Weed Density, Yield and Quality Parameters in Winter and Spring Sown Lentil (Lens culinaris Medik.) | Chapter 10 | Emerging Issues in Agricultural Sciences Vol. 4

 In this study, by utilizing a red lentil type of Kafkas, it is aimed to indicate the influence of cold and spring sowing weed control designs (no control, one time help weeding, two times help weeding and poison) on yield and grain character clearly through the randomized blocks detached plots trail desing method under the rainfeed conditions. According to the got results, winter planted and 2 times grass control method gives the highest plant crest 29.83 cm, pod per plant 25.40, grain per plant 24.13, plant organic yield 3.56 g, unit region biological yield 819.3 g/m2, grain yield 180.76 g/m2, and 100 essence weight 3.67 g. But seed protein content 22.52% and first pod height 12.16 cm were got from 2 times grass control spring sowing plots. Plant height, first pod height, plant piece yield, plant biological yield, organic yield and grain yield (m2), 100 essence weight, and grain protein content were concerned as statistically by sowing time. On the other hand yield and characteristic components stirred by weed contol methods they are indifferent groups according LDS test, except 100-seed weight. Although at plant altitude parameter, 2 times grass control and herbicide plots were likeness as statistically. When results evaluated, for lentil cultivation 2 times grass control and winter sowing gives better results in terms of yield elements and grain feature.

Soil pH Interference in the Behavior of Weak Acid Herbicides | Chapter 5 | Recent Progress in Plant and Soil Research Vol. 1

 Herbicides derived from weak acids can be affected in their sorptive capacity when they interact with soil pH. As a result, when their pH rises, they can reduce their sorption in the soil and increase their leaching. This increases the herbicide's bioavailability in the soil, resulting in a greater control effect on weeds and crop injuries. However, if there is rain, the herbicide may be transported by leaching in the soil profile to the deeper layers of the active seed bank, reducing weed control. Given the foregoing, it is critical to investigate the interactions with soil pH in risk assessment and agronomic procedures. The analysis of the herbicide's behavior in the soil, as well as the correct positioning of the product in chemical management. This chapter explains how the pH of the soil can affect the behavior of weak acidic herbicides in a chemically understandable way for agrarian scientists. The difference in electric charges of ionized herbicides and colloids was critical in understanding how these interactions occur, which are influenced by soil type and pH. Finally, it is expected that professionals who work with herbicides will be able to better understand some of the interactions of herbicide chemical molecules with soil and make appropriate recommendations.
