China’s agricultural sector faces challenges because most farms are still small scale. China’s policy is to encourage the consolidation of farms and promote farms that are larger in scale. A question that arises is: Are China ’s farms growing? The goal of the present paper is to determine whether large farms in China have emerged or if farms remain small. To meet this goal, we systematically do...

This study was undertaken in order to examine whether any connection existed between the amounts of iron in forage and the sporadic occurrence of scrapie observed in certain parts of Iceland. As iron and manganese are considered antagonistic in plants, calculation of the Fe/Mn ratios was also included by using results from Mn determination earlier performed in the same samples. Forage samples (...

Abstract Livestock breeding in Uzbekistan is established mainly small farms, and more than 80 percent of the total product produced them. With development animal husbandry there a demand for equipment used preparation feed, including concentrated feed by crushing grains. Taking this into account, small-sized grain grinder device grinding grains was developed farms. The height 1170 mm, length 50...

abstract the existence of various perceptions related to the efficiency of water use in agricultural sector can hamper the development of appropriate water resource conservation policies. particularly, when there has been an emphasis on increasing water use efficiency by improvement in irrigation systems. the main purpose of current study is to estimate excess water use for a sample of 15 farms...

Eco-efficiency is concerned with the efficient and sustainable use of resources in farm production and land management. It can be increased either by altering the management of individual crop and livestock enterprises or by altering the land-use system. This paper concentrates on the effects of crop sequence and rotation on soil fertility and nutrient use efficiency. The potential importance o...

We propose a general technique related to the polytopal Sperner lemma for proving old and new multilabeled versions of Sperner’s lemma. A notable application of this technique yields a cake-cutting theorem where the number of players and the number of pieces can be independently chosen. We also prove multilabeled versions of Fan’s lemma, a combinatorial analogue of the Borsuk-Ulam theorem, and ...

Let {Xi},i = l, • • • , be a sequence of independent and identically distributed random variables with density function f(x). We shall assume throughout that EXi=p>0. Let {Sn}, n = l, • • • , be the sequence of cumulative sums Sn= 23"-1 -^«'Let H(x) = 23»= i P(Sn ^x) and h(x)=H'(x). Since H(x) is nondecreasing, h(x) is defined for almost all x. Let A be any Borel set of positive real numbers an...
