  • In agriculture profession high output is demanded with limited resources and machines are the costlier investment to the agriculture for a marginal and poor farmer. The accuracy and precision of an agricultural machine can be increased using the electronics and computing systems however it increases the cost of the machines. In spite of costlier investments, many researchers have been conducted the study on mechatronics application in precise sowing operation in recent years.

  • At the present time, the most widely used machine for seed and oilseed planting is a seed drill with a roller-type-metering device. Due to nonuniform spacing of seeds along the rows and lack of control on planting depth, this machine aggravates the growth related problems and degrades the quality of a sensitive crop such as oilseed rape.

  • An experiment was conducted during rabi 2016 to the study effect of precision farming technologies including fertigation and black polythene mulching to know the effect on growth, yield and quality of okra [Abelmoschus esculentus (L.) Moench] seeds var. Arka Anamika at ICAR-Indian institute of Horticultural Research Hesaraghatta, Bengaluru. The experiment consisted of ten treatments were laid out in a Randomised Block Design (RBD) with three replications. The maximum plant height (115.52 cm), number of branches (3.10), stem girth (4.76 cm), leaf area index (2.

  • A seed metering mechanism of conventional precision planters are usually driven by ground wheel with chain and sprocket system and these mechanisms are of mechanical type. They are less efficient as there is a number of losses while transmitting the power. Due to continuous friction between moving parts, these devices are subjected to wear and tear; hence they require frequent maintenance. To improve the planting performance of precision planters, the best substitute is to develop an electronic meterized planter for maize.

  • Caffeine (1,3,7-trimethylxanthine) is naturally found in the leaves, seeds or fruits of over 63 plants species worldwide. It is contained highly in coffee, tea, cacao beverage products. Caffeine showed good effects in enhancing performance and perception of exercise, reducing fatigue and drowsiness, and improving memory and learning effects. Although caffeine intoxications are rare, they showed its unhealthy potential factor, resulting in tachycardia, atrial arrhythmias, convulsions or even coma.
