Effect of Various Soil Management Practices on the Vigour Yield and Quality of Sky Spur Apple Cultivar

The present investigation was carried out to study the effect of off season soil management practices on yield and quality of turmeric (Curcuma longa L.) cultivars. The experiment was laid out in a Factorial Randomized Block Design with ten treatments in three replications consisted of five off-season land management treatments viz., fallow (S1), summer ploughing 2 times (S2), summer ploughing 1 time (S3), solarization with transparent polyethylene film of 0.05 mm thick for 40 days (S4) and black polyethylene film for 40 days (S5). It was tested with two popular cultivars viz., Curcuma longa -1 CL-1 (V1) and Curcuma longa-2 CL-2 (V2), collected from Erode and Chidambaram. Various yield components were recorded at the time of harvest and were analysed. The yield attributing characters viz., number, length, girth and weight of mother, primary and secondary rhizomes were recorded. The treatment where solarization with transparent polyethylene film of 0.05 mm thick was tested recorded the highest yield and yield attributing characters when compared to other treatments. The same treatment also exhibited the highest fresh rhizome yield per plant, curing percentage and cured rhizome yield. The quality parameters like curcumin, oleoresin and essential oil content were also showed superior performance in the treatment where solarization with transparent polyethylene film of 0.05 mm thick was applied.

Nutritional quality of most high valued crops including carrot can be influenced by soil management practices. A field study to evaluate soil management improvement effect on nutritional quality of carrot was carried out in two contrasting cropping seasons of two rainfall regimes ranging from 600 mm to 800 mm in 2016 and 2017 at Mampong in the Forest-Savannah transition zone of Ghana. Three rates of soil amendments using biochar rates of 0, 5 and 10 tons/ha and five rates of inorganic fertilizers (NPK 15:15:15 at 200 kg/ha; P&K 50:50 at 50 kg/ha; P&K 50:100 at 50 kg/ha; Liquid Fertilizer at 1 L: 200 L Water/ha; and the control were applied using 3x5 factorial in RCBD. The combined analysis for the different treatments showed that NPK at 200 kg/ha+10 ton/ha biochar gave the highest protein content while Liquid fertilizer+5 ton/ha biochar gave the highest beta-carotene and total carotenoid contents in carrot root during the minor cropping season of 2016. However, during the major copping season of 2017, a combination of liquid fertilizer +10 ton/ha biochar gave the highest protein content whilst NPK at 200 kg/ha +5 ton/ha biochar gave the highest carotenoid content for the carrot. Nutritional contents such as carbohydrate, beta-carotene and total carotenoids were boosted by soil amendments. This indicates that both biochar and inorganic fertilizers have varying effects on the nutritional qualities of carrot.

Abstract This chapter describes the guava fruit as well as the fruit set, growth, drop, harvesting, yield and quality (total soluble solids, total acids and ascorbic acid). Understanding the phenological cycle of guava and the effect of management practices on yield and fruit quality allows management practices to be modified to develop strategies which should lead to productivity gains for different pruning or chemical application times. As the effects of various treatments and times of application on yield and fruit quality for different cultivars and climatic zones are known, it is possible to decide on the optimum time to apply treatments knowing what the quality of the fruit will be, the time that the fruit will be harvested, expected yield and the critical times to apply management practices.

Fusarium graminearum is a causal agent of Fusarium head blight (FHB), a disease that reduces yield and quality of cereal crops and contaminates grain with mycotoxins that pose health risks to humans and livestock. Interpopulation antagonistic interactions between isolates that produce different trichothecene mycotoxins can reduce FHB in wheat, but it is not known if interactions between isolates with a shared population identity that produce the same trichothecenes have a similar effect. Using isolates from the predominant F. graminearum populations in North America (NA1 and NA2), we examined intrapopulation interactions by comparing growth, disease progression, and toxin production of individual isolates with multi-isolate mixes. In vitro, mycelial growth was significantly greater when most NA1 and NA2 isolates were cultured individually versus when cultured as a mixture of isolates from the same population. In susceptible wheat Norm, FHB generally progressed faster in heads inoculated with an individual isolate versus a multi-isolate mixture, but the antagonistic effect of intrapopulation interactions was more pronounced for NA1 than NA2 isolates. By contrast, in moderately resistant wheat Alsen, mixtures of isolates from either population caused obvious reductions in FHB development. Mycotoxin contamination was not consistently affected by intrapopulation interactions and varied depending on the interacting isolates from either population. Our results indicate that antagonistic intrapopulation interactions can influence FHB in controlled environmental conditions. Understanding if the regional composition of pathogen populations similarly influences FHB in the field could improve disease forecasting and management practices.
