stalks. Similar results were reported by Bhardwaj et al. (1996) for kenaf consumption by goats (Capra hicus). A broadleaf forage crop grown in rotation with winter wheat (TritiUnger (2001) in the Texas Panhandle (average annual cum aestivum L.) would diversify dryland crop rotations in the central Great Plains. Kenaf (Hibiscus cannabinus L.) provides good quality precipitation 475 mm; average J...

abstract the increasing of yield per unit area is usually achievable by improving the soil fertility level through using (chemical) fertilizers. the purpose of the present research was to evaluate the 6 extraction methods including olsen, morgan, ammonium bicarbonate-dtpa, colwel, bray and mehlich 3 in order to specify a suitable extractant(s) for estimating available phosphorus through using 2...

Two cultural treatr7zents were applied in an overstocked loblolly pirze (Pinus taeda L.) plantation (2,900 trees/ha after eight growing seasorzs): precom~nercial tlzinning (Yes or No) to 747 tt-ees/lza after the eighth growing season and broadcast fertilizatiorz (Yes or No) with diamrrzonium phosphate (150 kg/ha of P and 135 kg/ha of N) early in the ninth growing season. Total height and diamet...

Grazing warm-season grass pastures with stocker cattle (Bos taurus) is an important economic activity in the southern Great Plains, and substantial increases in the price of N fertilizer have negatively affected profi tability of forage producers. The goal of the study was to determine if bermudagrass [Cynodon dactylon (L.) Pers.] pastures interseeded with either annual or perennial legumes are...

wheat (triticum aestivum l.) was grown in earthen pots containing soil of balkasar soil series (sandy loam) in green house at the department of soil science and swc, pir mehr ali shah arid agriculture university, rawalpindi during rabi season, 2007. the crop was treated with two levels of phosphorus (40 and 80 kg p ha-1 ) in the form of ssp, tsp, np and dap. a basal doze of 100 kg n and 60 kg k...

The effect of seed inoculation by phosphate solubilizing microorganisms and different levels of phosphorus chemical fertilizer on forage and grain quality of barley (Karoon x Kavir cultivar) was studied in Experimental Farm of College of Agronomy and Animal Sciences, University of Tehran during 2006-2007 growing seasons. Three phosphorus fertilizer levels of 0 (control), 30 and 60 kg ha were al...

An experiment was conducted to determine animal performance and gain/ha of beef steers (mean initial wt.: 241 kg) grazing a conventional sorghum x sudan hybrid (C) versus its near isogenic brown midrib (BMR) variety. The experiment was conducted during the summers of 1999 and 2000 in the Texas Panhandle. During both summers 8 pasture plots (2.2 ha) were blocked by location and randomly assigned...

The aim of the present study was to evaluate the response of grain yield, phosphorus (P) use efficiency (PUE, g yield g–1 P available) and related root traits of wheat and pea to different P availabilities in a high yielding environment (e.g.: yield higher than 10 Mg ha-1 for wheat). Two experiments were conducted in southern Chile. Treatments consisted of the combination of (i) two crops (spri...

Structural best management practices were implemented throughout the Cannonsville Reservoir Watershed (CRW) in an effort to reduce P losses to the reservoir. Yet long-term water quality control efforts within CRW are hindered by continuous P build-up in the soils resulting from dairy farm P imports exceeding exports. Addressing the P imbalance problems and maintaining economic viability of the ...

The effects of nitrogen (N) addition on productive and physiological traits of Triticumdicoccum were assessed under two N levels (0, unfertilized, and 90 kg N ha−1) in fieldconditions, in two growing seasons. In the study case, the N supply (90 kg N ha−1) was appliedin three-split applications (20% at pre-plant stage, 40% at tillering stage, 40% at stemelongation). In unfertilized conditions, t...
