The paper is devoted to the study of deflector nozzles rain irrigation machines. selection parameters nozzle artificial sprinkler machines on a scientific and practical basis allows for correct organization ecologically safe irrigation. article presents results research short-distance with deflector.

water shortage in the agricultural sector is currently a major challenge in crop production. the more efficient water usage is that which increases yield without increasing water use. thus, a determination of the water-yield relationship is essential. a field study was conducted to examine water-yield relations in three genotypes of soybeans, including optimum irrigation depth, a comparison of ...

system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...

A field experiment was conducted at Wetland farm, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during summer 2022 to study the effect growth and yield parameters greengram under different irrigation methods. The laid out in randomized complete block design having seven treatments replicated thrice. treatment are T1: Check basin method (Line sowing), T2: (Broadcasting),...

ABSTRACT Weed interference is one of the factors that reduces carrot yield considerably. The aim this study was to determine periods weed in carrots cultivated under two localized irrigation systems. experiment used a completely randomized block design, with three replications, using split plot scheme. plots consisted systems (drip and micro sprinkler) subplots corresponded duration coexistence...

8 The modernization of irrigation districts in Spain is based on the construction of 9 collective pressurized networks equipped with remote control systems. In this paper, a 10 simulation approach is used to explore the benefits of introducing a collective solid-set 11 irrigation control software. The controller works in combination with a district 12 management database, real time evapotranspi...

For resolving the problem of sprinkle repeated, overtaken and went beyond in irrigation, it is important to research the approach of irregular boundary area. The equation of range and flow for achieving the square and triangle spray were deduced. Pressure is proportional to range. Specific method of changing the sectional area was put forward for achieving square and triangle spray. Adopted MAT...

J. Econ. Enlomol. 72: 599-601 (1979) Time of tuber infestation by Phthorimaea operculeLla (Zeller) was markedly affected by the type of irrigation system employed. Tuber infestation under furrow irrigation was above 25% for 4 wk prior to vine senescence while sprinkler irrigated potatoes sustained less than 5% damage during this period. After irrigation was terminated, infestation increased rap...

Phenamiphos, ethoprop, and carbofuran each at 6.7 kg a.i./ha were applied to squash, southern pea, and corn via injection into a sprinkler irrigation system. This method was then compared with a conventional application of phenamiphos and ethoprop granules spread on the soil surface and incorporated into the top 15 cm for control of Macroposthonia ornata and Meloidogyne incognita. Nematode popu...

Future wireless communication environments offer many possibilities for new services. Users will not be satisfied with simply being connected, but they will require useful services built on top of the wireless networks. iClouds is an architecture which offers spontaneous mobile user interaction, collaboration, and transparent data exchange in mobile ad hoc networks. In this paper we present sev...
