Correlation and calibration of soil potassium availability with rice yield and nutritional status
Soil testing is an important tool for estimating soil K availability and determining how much fertilizer must be applied to realize crop yield potential and minimize fertilizer costs. Our primary objectives were to correlate relative rice (Oryza sativa L.) yield with Mehlich-3 and 1 mol L–1 HNO3 extractable K, define sufficient whole-plant K concentrations at panicle differentiation (PD) and ...

Hormonal changes caused by the xenia effect during grain filling of normal corn and high-oil corn crosses
The xenia effect results from the cross-fertilization of nonrelated lines of crops, which causes a grain to produce a germ or embryo that is much larger than average. It is a significant genetic component in TopCross grain production systems, which can affect grain yield and quality. This study measured hormone variations during grain filling of normal corn (Zea mays L.) hybrids, and normal corn ...

White wheat grain quality changes with genotype, nitrogen fertilization, and water stress
The production of hard white winter (HWW) wheats (Triticum aestivum L.) with acceptable protein content and quality over different environments requires the correct combination of genotypes and management practices. The objectives of this study were to evaluate moisture deficit and N management on grain protein and quality of seven HWW and two soft white winter (SWW) genotypes, and to identify ...

Rice growth, grain yield, and floodwater nutrient dynamics as affected by nutrient placement method and rate
The loss of major nutrients can be high in rice (Oryza sativa L.) fields, particularly rainfed rice, where water flowing from field to field during periods of high rainfall not only reduces the nutrient use efficiencies but also has the potential for environmental degradation. We examined the influence of deep point placement of N, P, and K briquettes compared to broadcast incorporation of N, P, ...

Response of upland rice cultivars to nitrogen fertilizer in the savannas of Nigeria
In the dry savannas of West Africa, cultivation of upland rice (Oryza spp.) under rain-fed conditions is expanding due to the introduction of the New Rice for Africa (NERICA; WARDA, Bouake, Cote d'Ivoire) but appropriate N recommendations for these new cultivars are lacking. The present study evaluated the response of four NERICA rice cultivars, their parents (WAB 56-104 (O. sativa, tropical ...

Management practices to minimize tan spot in a continuous wheat rotation
In the central United States, practices that maintain residue in wheat (Tritricum aestivum L.) often lead to yield losses from tan spot (Pyrenophora tritici-repentis) infections. Tillage, fungicides, N fertility, and resistant varieties may reduce tan spot severity. Studies were conducted over five location-years to determine wheat yields and tan spot severity across three residue levels ...

Triangular transplanting pattern and split nitrogen fertilizer application increase rice yield and nitrogen fertilizer recovery
Field experiments were conducted to evaluate the effects of improved crop management (OPT) for irrigated rice (Oryza sativa L.) on grain yield and N recovery efficiency in southwestern China. In the OPT treatment, rice seedlings were transplanted in a triangular spatial pattern and the N fertilizer was split, based on the difference between the estimated total N requirement and the soil and ...

Linking Wisconsin dairy and grain farms via manure transfer for corn production
One relatively under-used manure management strategy employed by dairy farmers is to transport and apply manure onto the fields of nearby grain farmers. While this system offers advantages to both parties, little of the existing research on manure management has been conducted on grain farms. As part of an effort to link grain and livestock farms in southern Wisconsin, 20 on-farm trials were ...

Seeds of change in sub-Saharan Africa
In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped grain production at an unsustainable ...

Why You May Want To Purchase A Rice Husk Carbonizer
The harvesting of rice is certainly a profitable business. This the type of food that is used by just about any country. Once the harvesting is done, the residue in the harvest is usually utilized for fertilizer. Or else, it may be sent to other areas for processing. This may be a costly endeavor which may cut in the profits of any business that may be harvesting rice. However, if you could ...

The Importance of Scales in the Agricultural & Farming Industry
Weighing scales are essential and necessary equipment required for a wide range of applications. Whether intended for personal, industrial or commercial use, they serve one important function – providing accurate weight measurements for varied loads. In the agricultural sector, scales are indispensable tools and without them, it would be almost impossible to manage farms or carry out trade! ...

Tracking Your Data In All Your Unusual Places
Let’s be honest: I say “level measurement,” you think “fluid in a tank.” It’s ok; most people do. And if we’re really honest with each other, you can admit that you probably were thinking about an industrial tank, related to factory production of some kind. And again, it’s ok. But there’s so much more to level measurement! One of fastest ...

Boost grain preservation before production
Better grain storage would save money and feed over a billion, says Digvir S. Jayas. It deserves more attention. Annually over 2.6 billion tonnes of grains — cereals, oilseeds and pulses — are grown and then stored along the chain from producers to consumers. Most countries do not systematically report how much grain becomes unfit for human consumption during storage, but anecdotal ...

U.S.-India: Dealing With Monsoon Failure
The scene plays out in India. At a reception, I met the head of Indian operations for Esso (now ExxonMobil). When I asked him how business was, he said it was great. In particular, diesel sales to fuel irrigation pumps were nearly double the previous year’s level. Why? Because farmers were pumping continuously to try to save their crops. Soon after, I met an embassy staff person, an avid ...

6 Series PTO Shaft – Replacement of Bondioli & Pavesi PTO Shaft
A 6-Series PTO (Power Take-Off) shaft is a form of the shaft made of metal that is utilized for transferring power to a tractor or another source of power to a device or attachment. Its "6 Series" designation refers to the standard dimensions and specs of the shaft such as its length, diameter, and the spline's profile. PTO shafts of the 6 Series are often employed in agricultural applications ...

Could food shortages bring down civilization?
One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...
