Avaliação de cultivares de milho verde em pariquera-açu

Abstract: Os cultivares de milho Cargill 742, Cargill 408, Cargill 511, Cargill 501, Agroceres 162, Pioneer X 307, IAC Phoenyx 1918, IAC Phoenyx o2 1313, IAC Maya XIX e BR 126 foram avaliados em duas epocas, em plantios de inverno (maio e junho de 1983) na Estacao Experimental de Pariquera-Acu, SP, com o objetivo de identificar os melhores para a producao de milho verde. Foram estudadas as seguintes caracteristicas agronomicas: estande final; numero e total de espigas comerciaveis; peso de espigas com palha, comerciaveis e total; indice de espigas (numero de espigas comerciaveis/estande final) e peso medio de espigas comerciaveis. Os cultivares se diferenciaram quanto a populacao final de plantas; indice de espigas; resistencia a Helminthosporium turcicum Pass.; ciclo do plantio a colheita, e produtividade: o Cargill 742 e o Cargill 408 foram os mais produtivos, superando o Agroceres 162, e mostraram ainda menor incidencia de Helminthosporium turcicum, maior indice de espigas e precocidade. As condicoes climaticas foram atipicas, desfavoraveis a cultura do milho, provocando baixo nivel de produtividade, que ainda foi lucrativo.

Assessment of insurance for paddy production: a case study in Indonesia

Abstract: The present study demonstrated the importance of designing insurance as a part of broader risk management, using pilot insurance for rice farmers in East Java, Indonesia, as a case. An independent-sample t-test, using historical data on the areas of monthly rice harvest failure at regency level for the recent 10 years, finds that harvest failure during the rainy seasons in a group of the regencies located in the Bengawan Solo River Basin is significantly greater than the other group consisting of the remaining regencies in the province. This is due to frequent floods, which are largely attributed to the declining function of the Wonogiri reservoir as the primary flood control facility. It suggests the necessity of risk prevention measures, such as those to pump out dead storage and upgrade spillway capacity, to allow insurance to work in the basin. The present study also investigated a feasibility of weather index insurance. It compares the correlation coefficients and statistical significance of monthly ...

Geo–tectonic Position of Tin Polymetallic Mineralization Zone in the Southern Da Hinggan Mountains Area, Inner Mongolia, China: An Introduction to This Special Issue

Abstract: As a part of the main activities of Japan-China technical cooperation project, a test survey area, approximately 5,000 km2, was established for the implement of its geological and geochemical research program. A major mineralization zone called Huanggang–Ganzhuermiao–Wulanhaote Sn-Cu polymetallic mineralization zone is recognized in the southern Da Hinggan Mountains area. The southern half of this zone is known as the sole Sn-mineralization zone in North China. The survey area lies in this prominent zone. As the most of the papers presented in this issue have concerns to the geology and mineralization in this survey area, this report was prepared to introduce geo-tectonic situation of the Sn-Cu polymetallic mineralization zone in the Inner Mongolia orogenic belt. The belt is divided into four tectonic facies (from NW to SE); I: Wuliyasitai volcano-plutonic zone, II: Hegenshan ophiolite melange zone, III: Sunitezuoqi volcano-plutonic zone, IV: Wenduermiao ophiolite melange zone. The subject Sn-Cu polymetallic mineralization zone is situated in the southeastern part of the Sunitezuoqi magmatic zone. About this Sunitezuoqi magmatic zone, three geo-tectonic characteristics are pointed out. In late Carboniferous to early Permian period, subduction of Hegenshan oceanic crust occurred, which accelerated volcano-plutonic activities and brought about basic to intermediate volcanic rocks of tholeiitic to calc-alkaline series represented by Dashizhai Group in the Sunitezuoqi magmatic zone. Late Jurassic to early Cretaceous acidic rocks representing the most culminated volcanism and plutonism in Mesozoic era in the Da Hinggan Moutains area are distributed very extensively in and around the Sn-Cu polymetallic mineralization zone. The Proterozoic metamorphic basement rocks called Xilinhaote complex are distributed close to the mineralized area in the Sunitezuoqi magmatic zone. Although the real mineralization was known associated with Mesozoic acidic to intermediate volcano-plutonic activities, it is thought that the lower Permian Dashizhai volcanic rocks and pre-Cambrian basement rocks might have played certain significant role in the process respectively of extraction of elements and formation of the magma favorable for such mineralization in the Sunitezuoqi magmatic zone. It would be necessary to give further considerations to these three geological units in relation to the Sn-Cu polymetallic mineralization.
