In hops (Humulus lupulus L.), irrigation by flooding the inter-row can carry away suspended particles and minerals, causing gradients in soil fertility. The effect of more than 20 years on plants was evaluated two hop fields measuring plant variables multiple points along rows. a second experiment 1000 kg ha−1 lime applied incorporated into to assess whether liming could moderate any gradient c...

We describe a number of algorithms for the model for parallel computation called Parallel Alternating-Direction Access Machine (padam). This model has the memory modules of the global memory arranged as a 2-dimensional array, with each processor assigned to a row and a column, the processors can switch synchronously between row and column access modes. We study the issues of inter-processor com...

This work proposes a novel algorithm for performing robust feature-based stereo-matching, without the ordering constraint. The calculation of the disparity map is decomposed to a set of disjoint intra-row subproblems, each one having two objectives: the search for a high con"dence intra-row matching and the enforcement of "gural continuity at the inter-row level. A separate genetic algorithm (G...

This paper presents a mapping method for wide row crop fields. The resulting map shows the crop rows and weeds present in the inter-row spacing. Because field videos are acquired with a camera mounted on top of an agricultural vehicle, a method for image sequence stabilization was needed and consequently designed and developed. The proposed stabilization method uses the centers of some crop row...

This study attempts to optimize the arc-shaped coned disk affecting uniformity of earlier designed fertilizer apparatus (FA), in particular, for application rice–oil rotation region middle and lower reaches Yangtze River, China. Based on theoretical analysis, a circular with curvature gradual decline (GD) from top bottom was designed, equation cone determined. The EDEM discrete element software...

The purpose of this research is to study the effect deep loosening row spacings on physical properties soil and yield organic potatoes. Two variants cultivation were used in spacings: usual 25 cm deep. was carried out with a row-crop chisel cultivator. Its design developed at institute. Analysis data obtained as result experimental studies showed that had positive compaction both inter-row widt...

In accordance with the agricultural row-crops cultivation practices adopted in Central Asian region, machine-tractor units carry out a large number of passes through field during growing season. Consequently, individual sections fields are repeatedly affected by running systems these machines, which negatively affects soil fertility. The universal row-crop tractors used cotton production have t...
