Np Fertilizer

Field experiments were carried out at the Department of Agronomy of the Poznań University of Life Sciences to determine the effect of the depth of NP fertilization placement in maize cultivation on the number of plants after emergence. The adopted assumptions were verified based on a six-year field experiment involving four depths of NP fertilizer application (A1—0 cm (broadcast), A2—5 cm (in rows), A3—10 cm (in rows), A4—15 cm (in rows)). The objective of this study was to assess NP fertilizer placement depth, in conjunction with the year, on the number of maize (Zea mays L.) plants after emergence using the additive main effects and multiplicative interaction model. The number of plants after emergence decreased with the depth of NP fertilization in the soil profile, confirming the high dependence of maize on phosphorus and nitrogen availability, as well as greater subsoil loosening during placement. The number of plants after emergence for the experimental NP fertilizer placement depths varied from 7.237 to 8.201 plant m−2 during six years, with an average of 7.687 plant m−2. The 61.51% of variation in the total number of plants after emergence was explained by years differences, 23.21% by differences between NP fertilizer placement depths and 4.68% by NP fertilizer placement depths by years interaction. NP fertilizer placement depth 10 cm (A3) was the most stable (ASV = 1.361) in terms of the number of plants after emergence among the studied NP fertilizer placement depths. Assuming that the maize kernels are placed in the soil at a depth of approx. 5 cm, the fertilizer during starter fertilization should be placed 5 cm to the side and below the kernel. Deeper NP fertilizer application in maize cultivation is not recommended. The condition for the use of agriculture progress, represented by localized fertilization, is the simultaneous recognition of the aspects of yielding physiology of new maize varieties and the assessment of their reaction to deeper seed placement during sowing.

Corn, as it is said in Mexico (Zea mays L.) is an annual grass native to America, specifically from the central-western region of Mexico. There is a great diversity of varieties of corn. Ethnic groups and farmers have selected this crop for thousands of years for different uses, and have created and preserved the right types of corn for specialized uses. Based on all of the above, the objective of this research was to identify the processes of the preparation of corn flour (masa) and its uses in the gastronomy of the southern state of Campeche, Mexico. In order to achieve the research, a total of 28 establishments were visited, 10 dedicated to the production of corn flour (masa) and 18 focused on the preparation of regional snacks based on corn masa. Basically two ways of preparing corn flour were observed. Similarly, for the preparation of the dough to make regional snacks, four styles were identified. In the city of Escárcega 14 different types of regional snacks are sold. Fried or comal empanadas are the ones in greatest demand. The south of the state of Campeche presents a gastronomic wealth in the preparation of regional snacks, since it has influences from the central and southern communities of Mexico, so it is important to consider the area as an area rich in its gastronomy. El maíz, como se dice en México (Zea mays L.) es una gramínea anual originaria de América, concretamente de la región centro Occidente de México. Existe una gran diversidad de variedades de maíz. Los grupos étnicos y agricultores han seleccionado este cultivo por miles de años para diferentes usos, y han creado y conservado los tipos adecuados de maíz para usos especializados. Con base en todo lo anterior, el objetivo de la presente investigación fue identificar los procesos de la preparación de la harina de maíz (masa) y sus usos en la gastronomía del sur del estado de Campeche, México. Para el logro de la investigación se visitaron en total 28 establecimientos, 10 dedicados a la elaboración de la harina de maíz (masa) y 18 enfocadas a la preparación de antojitos regionales a base de masa de maíz. Se observaron básicamente dos formas de preparar harina de maíz. De igual forma para la preparación de la masa para elaborar antojitos regionales fueron identificados cuatro estilos. En la ciudad de Escárcega se comercializan 14 tipos diferentes de antojitos regionales. Las empanadas fritas o al comal son las de mayor demanda. El sur del estado de Campeche presenta una riqueza gastronómica en la preparación de antojitos regionales, ya que presenta influencias de comunidades centro y sur de México, por lo que es importante considerar al área como una zona rica en su gastronomía.

Maize (Zea mays L.) is the most popular highland cereal in South Asia, and hybrids are being promoted to enhance yields. Thus, a field study evaluated the growth and yields of two hybrid and two open-pollinated varieties in two major (wet) and minor (dry) seasons of Sri Lanka, when grown as a mono crop and when intercropped with mungbean [Vigna radiata (L.) Wilczek]. The growth and yields of the hybrids were greater under both mono and mixed crop conditions in the major seasons, while the performance of open-pollinated varieties was significantly superior in the minor seasons, when the crops are subjected to moisture stress due to lower rainfall. The potential of using different types of maize for smallholder cropping in South Asia in the two seasons is presented.

Agricultural ecosystems are one of the largest global contributors to nitrate (NO3−) contamination of surface- and groundwater through fertilizer application. Improved fertilizer practices are needed to manage crop nutrient supply in corn (Zea mays L.) while minimizing impacts to clean water reserves. The goal of this study was to compare current nitrogen (N) fertilizer practices (urea at planting) with “packages” of improved management practices (a combination of right timing and product) that farmers potentially use. We conducted measurements in a continuous corn system from November 2015 to May 2017 at a large field scale (four 4 ha plots). Nitrate concentration was measured below the root zone and drainage estimated using a soil water budget approach in which evapotranspiration was measured using the eddy covariance method. The objective was to compare NO3−-N leaching from fields receiving urea vs. urea + combination of nitrification and urease inhibitors (NUI) fertilizer applications at planting, urea–ammonium nitrate (UAN) vs. UAN + NUI applied at sidedress, and a combination of these practices: urea + NUI at planting vs. UAN at sidedress. Drainage was only significant in the non-growing season. Neither fertilizer products applied with NUI at planting or sidedress proved to significantly reduce NO3−-N leaching. The combination of delaying fertilization to sidedress and applying UAN significantly reduced the soil water NO3−-N concentration compared with urea + NUI at planting (mean of 5.2 vs. 6.7 mg L−1) but only in 2015–2016. Based on these results, applying UAN at sidedress is recommended, although additional study years are needed to confirm those results.

The maize (Zea mays L. ssp. mays) has several related species, called teosinte, which are distributed in various subspecies of Zea and other genera. Among the different types of corn, sweet corn shows a great potential for human food. This type was originated from mutations, which increased the amount of polysaccharide in the endosperm. In Brazil there are populations of sweet corn, common maize and teosinte, however, little is known about their genetic variability. Hence, the aim of this present paper was to analyze the genetic variability in two populations of sweet corn (BR 400 and BR 402), two common corn (Pampa and Suwan) and teosinte, using microsatellite markers. The results showed a low intra-population genetic variability in populations of maize, and high variability for the population of teosinte, suggesting that the maize populations may have limitations in future cycles of breeding.

Fertilizer Rates

Depletion of nitrogen and phosphorus in terraced hilly areas of Rwanda has lowered maize (Zea mays L.) production. Trials were carried out in 2017 and 2018 in four-year-old-terraced Lixisols and Acrisols of medium and high altitudes to determine effect of nitrogen and phosphorus fertilizer application rates on maize yields. A factorial arrangement of four levels of nitrogen (0, 60, 120 and 180 kg N ha-1) and phosphorus (0, 40, 80 and 120 kg P2O5 ha-1) in a randomized complete block design with 3 replications, was used. Results showed that combinations of 120 - 180 kg N ha-1 and 80 - 120 kg P2O5 ha-1 resulted in significantly (P less than 0.05) higher increases in plant height (45 – 60 % and 56 – 70 % over the control), stem collar diameter (63 – 74 % and 43 % over the control) and grain yields (3 times over the control; i.e. 6.40 – 6.46 t ha-1 and 6.02 - 6.12 t ha-1) in medium and high altitude sites. The optimum fertilizer rates are 176.6 kg N ha-1 and 96.2 kg P2O5 ha-1 in terraced Lixisols of medium altitude area. Land use needs to adjust fertilizer application to these optimum rates for enhanced maize yields in this area and other regions with similar agro-ecological characteristics. Further studies on integrated effects of N and P fertilizers are recommended.
