The Dutch flower bulb market, the aims of the Dutch government to develop more environmentally friendly approaches to agriculture by reducing inputs and emissions, and the economic implications of such a shift in policy to the bulb market are discussed. Reducing pesticide inputs by rotating crops, selecting suitable cultivars and using pathogen-free planting material, reducing inorganic fertilizer inputs by properly assessing the needs of crops and using organically-based nutrient sources, and reducing emissions to the environment by using better application techniques are advocated. Progress in the development of integrated bulb production schemes at 3 experimental farms in the Netherlands (at Sint-Maartensbrug, Hillegon and Zwaagdijk) is discussed.

Early Fixation

Adhesive use for fixation in hernia repair allows for complete and immediate mesh surface area adherence. Little is known about the fixation strengths of the products and application methods available. The purpose of this study was to compare the immediate and early strength of fixation of Tisseel™ and Evicel™ using hand and spray application techniques. Sixteen Mongrel swine underwent implantation of large-pore, mid-weight polypropylene mesh fixated with either Tisseel™ or Evicel™, applied by hand or with a spray apparatus. Time points studied were zero and four days. All samples underwent lap shear testing to quantify the strength of the mesh–tissue interface as an indicator of mesh fixation strength. Thirty Day 4 and 16 Day 0 samples were tested. Manually applied Tisseel™ mean fixation strength was 2.05 N/cm at Day 0 and 6.02 N/cm at Day 4. Sprayed Tisseel™ had mean fixation strength of 1.22 N/cm at Day 0 and 7.21 N/cm at Day 4. Manually applied Evicel™ showed mean fixation strength of 0.92 N/cm at Day 0 and 6.73 N/cm at Day 4. Mean fixation strength of sprayed Evicel™ was 0.72 N/cm at Day 0 and 6.70 N/cm at Day 4. Analysis of variance showed no difference between groups at Day 0 or Day 4. Immediate strength of mesh fixation could have significant implications for early recurrence and mesh contraction. This study demonstrates that no difference exists in immediate or early fixation strength between these two brands of sealants or their method of application.

Nesting Place

The farmers in Pangkalan Gelebak Village have the problem of their low agricultural productivity.  The high price of chemical fertilizers causes the ability of the population to purchase fertilizers to be deficient.  As a result, agricultural production is still far from optimal.  In addition, rice straw left alone in rice fields can become a nesting place for pests such as rats, leafhoppers, and others.  Therefore, it is necessary to transfer information on appropriate science and technology, which is environmentally friendly, to overcome the problems of farmers in Pangkalan Gelebak.  One way to overcome this is to provide counseling about the importance of processing rice straw into biofertilizers to increase production, train, guide, and practice techniques for making biofertilizers made from rice straw to increase agricultural production, especially rice, and practicing application techniques for biofertilizer made from rice straw.  Rice straw is the raw material for rice plants for farmers in Pangkalan Gelebak Village.  The method used is to make demonstration plots of rice plants organically, counseling about the importance of processing rice straw into biofertilizers to increase production, carried out from February to June 2018.  The results of using 400 kg/ha + 50 % chemical fertilizers can increase rice production from 3,5 tons/ha to 5,6 tons/ha (60,00% increase) when compared to using chemical fertilizers.

Spray Gun

Flemish greenhouse growers predominantly use handheld spray guns and lances for their crop protection purposes despite the heavy workload and high risk for operator exposure associated with these techniques. These spray application techniques have also shown to be less effective than spray boom equipment under many conditions. Handheld spraying techniques are less expensive, however, and they are more flexible in practical use. Many growers also erroneously believe that high spray volumes and pressures are needed to assure good plant protection. The aim of this work was to evaluate the spray deposition, penetration, and uniformity between a manually pulled horizontal spray boom as compared with a spray gun under controlled laboratory conditions. In this study, we evaluated six spray application techniques, i.e., three spray boom and three spray gun techniques. In general, the deposition results were comparable between the spray boom and the spray gun applications. The spray boom applications, however, resulted in a more uniform spray distribution. At the plant level, the spray distribution was not uniform for any of the techniques used; the highest deposits were observed on the upper (or adaxial) side of the top leaves. Using spray guns at a higher spray pressure did not improve spray penetration in the canopy or deposition on the bottom (or abaxial) side of the leaves. Of the different nozzle types tested on the spray boom, the extended range flat fan XR 8003 gave the best results. Crop density clearly affected crop penetration and deposition on the bottom side of the leaves.

Leaf deposit and ground losses generated from spray application in mountain viticulture were evaluated. Four treatments were examined: A spray gun (1000 L ha−1, High-Volume Sprayer—HVS), a motorized knapsack sprayer (200 L ha−1, Low Volume Sprayer—LVS), and a conventional orchard mist blower calibrated at 500 L ha−1 (OS500) or 250 L ha−1 (OS250). The four treatments were assessed using the same tank concentration of tracer in two training systems: a trellis and a goblet. Sprayer treatment, vine side, and vine height significantly affected leaf deposit (p < 0.05). The absolute amount of leaf deposit increased with application volume, but when the amount of deposit was standardized to 1 kg ha−1, LVS resulted in the highest deposit, followed by HVS, OS250, and OS500. Deposition for the goblet system was ca. half that for the trellised vineyard. Ground losses standardized to 1 kg of tracer ha−1 were twice as high for HVS than for LVS, and four times as high for HVS than for OS250 and OS500, in both training systems. The current work suggests that low volume applications in vineyards are a viable and more environmentally friendly alternative than high volume treatments.
