“…Sticky belt stand is the method commonly used by researchers as a reference technique to test the seed spacing of each planter configuration (Panning, 1997;Molin et al, 1998;Singh et al, 2005;Anantachar et al, 2010;Zhan et al, 2010;Li et al, 2012;Önal et al, 2012;Yasir et al, 2012). In sticky belt stand test setup, the planter is placed above a moving belt covered with adhesive material so that the seeds that impacted to the belt remain at the point where they hit the belt.…”

“…Precision spacing also decreases seed scattering and disproportionate use of seeds due to uniform distribution (Anantachar et al, 2010). Identical germination and growth of plants make the subsequent operations, such as weeding and harvesting, easy with lower costs (Li et al, 2012;Taghinezhad et al, 2013).…”

RESEARCH ARTICLE OPEN ACCESSsliding or bouncing seeds on the sticky belt, especially at high belt speed (Kocher et al., 1998). However, it is convenient and has been tried by some researchers for evaluating a single row seed metering mechanism (Panning, 1997;Molin et al., 1998;Singh et al., 2005;Anantachar et al., 2010;Zhan et al., 2010;Li et al., 2012;Önal et al., 2012;Yasir et al., 2012). Among other alternative techniques, an opto-electronic seed spacing determination system has been developed (Kocher et al., 1998;Lan et al., 1999) which determines time intervals between seeds by detecting seed drop events relative to the planter. Panning et al. (2000) found that the spacing measured from the optoelectronic system was 15 mm greater than the theoretical one and the inaccuracy of the opto-electronic sensor was related to seeds with diameter <3 mm.With current advances in digital video technology, machine vision has shown potential as a sensing technology for seeding performance evaluation. In this case, spatial AbstractResearchers and planter manufacturers have been working closely to develop an automated system for evaluating performance of seeding. In the present study, an innovative use of acoustic signal for laboratory evaluation of seeding-machine application is described. Seed detection technique of the proposed system was based on a rising voltage value that a microphone sensed in each impaction of seeds to a steel plate. Online determining of seed spacing was done with a script which was written in MATLAB software. To evaluate the acoustic system with desired seed spacing, a testing rig was designed. Seeds of wheat, corn and pelleted tomato were used as experimental material. Typical seed patterns were positioned manually on a belt stand with different spacing patterns. When the belt was running, the falling seeds from the end point of the belt impacted to the steel plate, and their acoustic signal was sensed by the microphone. In each impact, data was processed and spacing between the seeds was automatically obtained. Coefficient of determination of gathered data from the belt system and the corresponding seeds spacing measured with the acoustic system in all runs was about 0.98. This strong correlation indicates that the acoustic system worked well in determining the seeds spacing.

Abstract. Paddy is a staple food for more than 93 countries and it will stay of life for future generations. Harvesting is one of the vital operations in crop production and timely harvesting is essential for getting maximum yield. Moisture content and forward speed are the two factors to overcome the post harvest losses and minimise the quantitative losses. In this paper, an artificial neural network is introduced to assess the grain losses in the field condition. The simulation result shows that the ANN method is appropriate and feasible to assess the grain losses. However, model results that, an error of (RMSE) 0.1582 for cutter bar loss, for threshing loss was 0.1299 and for separation loss was 0.1321. Hence, the ANN model help the operator / farmer to decide the time of harvest. It also minimizes the post harvest grain losses by considering crop and machine parameters.

RESUMO:Devido à grande diversidade de tamanhos amostrais empregados em avaliações de desempenho de mecanismos dosadores de sementes, o objetivo deste trabalho foi determinar o tamanho de amostra para experimentos em laboratório, com dosadores de sementes tipo disco alveolado horizontal e pneumático, e estudar o efeito dos tratamentos na regularidade de distribuição de sementes da cultura do milho. Para isso, foi conduzido experimento em condições de laboratório, conforme a norma ISO 7256/1. Os tratamentos compreenderam a combinação de quatro mecanismos dosadores (dois pneumáticos e dois de disco alveolado horizontal), com três velocidades de semeadura, de 0,7; 1,4 e 2,1 m s -1 . Foram utilizados os métodos de determinação do tamanho de amostra, intensidade de amostragem e bootstrap adaptado. Quanto à distribuição de sementes, os mecanismos dosadores estudados não apresentam diferenças na regularidade de distribuição, cuja regularidade caiu com aumento da velocidade de deslocamento na média dos dosadores. No que se refere ao tamanho da amostra, é possível reduzir, para a cultura do milho, para 103 espaçamentos entre sementes com nível de erro de 5% da média amostral, independentemente da velocidade de semeadura e mecanismo dosador utilizado. PALAVRAS-CHAVE: semeadoras de precisão, espaçamentos aceitáveis, bootstrap. SAMPLE SIZE FOR SEED MEETERS TESTS WITH CORN SEED IN CARPETED BELTABSTRACT: Because to the diversity of sample sizes used in performance evaluations of seed metering mechanisms, the objective of this study was to determine the sample size for laboratory experiments with horizontal plate and pneumatic seed meters, and treatment effects in the corn seed distribution. For this, experiment was conducted under laboratory conditions, according to the international standard ISO 7256/1. The treatments comprised a combination of four metering mechanisms (two pneumatic and two horizontal plate) with three sowing speeds, 0.7, 1.4 and 2.1 m s -1 . Methods were used for determining the sample size, sampling intensity and adapted bootstrap. Regarding the distribution of seeds, the meter mechanisms studied show no differences in the regularity of distribution, quality dropped with increasing speed. Referring to the sample size, can be reduced to 103 seed spacing with error level of 5% of the sample mean for the corn, independent of seeding speed and metering system used.
