Therefore, field experiments were conducted to evaluate the effect of the different timings of weed control on the growth and yield of upland rice in the 2015 and 2016 cropping seasons. The treatments consisted of periods when the crop was allowed to be weed-infested for the first 3, 6 and 9 weeks after sowing (WAS) and periods when the weeds were controlled for the first 3, 6 and 9 WAS. Two treatments of weed infestation and weed control until harvest were also included as the checks in a randomized complete block design with three replications. In both years, rice grain yields ranged from 0.6 to 0.8 t ha-1 in plots kept weed-infested until harvest, and from 3.5 to 3.9 t ha-1 in plots kept weed-free until harvest, indicating a 79-83% yield loss with uncontrolled weed growth. Weed infestation for the first 3 WAS did not cause a significant reduction in the growth and yi...

Field trials were, therefore, conducted to evaluate the effect of intra-row spacing and weed control methods on growth and yield of groundnut at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta in the forest-savannah transition zone of South west Nigeria during the cropping seasons of 2008 and 2009. Two intra-row spacings (15 and 25 cm) were evaluated which constituted the main plot treatments, while five weed control treatments (pre-emergence application of commercial formulation of metolachlor + prometryne (Codal) at 1.6 kg a.i/ha alone and the same treatment followed by supplementary hoe-weeding (SHW) at 6 weeks after sowing (WAS) and at 2.4 kg a.i/ha, 2 hoe-weedings at 3 and 6 WAS and weedy checks where weeds were not removed throughout the crop life cycle. All the treatments in different combinations were arranged in a split...

Hot soaking of the rice paddy was carried out in a thermo- statistically controlled hot water bath between the temperatures of 40 –60oC at soaking time of 30 – 240 min. Tempering was carried out by leaving the soaked samples for 24 hours. The samples were steamed in an auto-clave for 15 mins. The steamed samples were dried in an Open Shed and Cabinet dryer. The experimental data obtained from the drying methods were fitted to four thin layer drying models: Henderson and Pabis, Logarithmic, Two terms exponential, and Wang and Singh. Goodness of fit was based on highest R 2 and least SSE values. Dried samples of the paddies were milled in a rice miller and the physical qualities of the milled rice were obtained. Open Shed drying method has the highest R 2 and least SSE at 60oC for FUNAABOR- 1 and FUNAABOR -2 as predicted by Logarithmic and Two terms experimental models, while Cabinet drying metho...

The accuracy of the system depends mainly on the effectiveness of the signature features use in the system. Inability to extract robust features from a static image of ...
