Two sesame cultivars (Sesamum indicum L.) were evaluated using various 3 different sowing dates (20 th June, 10 th and 30 th July) and four nitrogen levels (0, 40, 80 and 120 kg N ha -1 ) at the New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during summer 2012. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement using f...

ABSTRACT- The influence of foliar application of urea, humic acid (HA), Zinc (Zn), and Boron (B) on potato yield (CV. Cror) was studied in a field experiment during 2010-2012 at the research farm of Nuclear Institute for Food and Agriculture (NIFA). Treatments consisted of i) Control, ii) Nitrogen-Phosphorous-potassium (NPK) (250,150,250 kg ha-1) , iii) NPK (125,75,125 kg ha-1) with 0.03% HA, i...

The relationships between N fertilizer rate, yield, and NO3 leaching need to be quantified to develop soil and crop management practices that are economically and environmentally sustainable. From 1996 through 1999, we measured yield and NO3 loss from a subsurface drained field in central Iowa at three N fertilizer rates: a low (L) rate of 67 kg ha(-1) in 1996 and 57 kg ha(-1) in 1998, a medium...

The influence of inorganic fertilizer application on the flavonoid, phenol and steroid content of the leaves of Ocimum gratissimum and Gongronema latifolium was investigated. Cultivated O. gratissimum and G. latifolium were treated with NPK (15:15:15) inorganic fertilizer at 100 kg/ha, 200 kg/ha, 300 kg/ha, 400 kg/ha and 500 kg/ha treatment levels in plastic planting buckets derived using the f...

Nitrogen is essential for both vegetative and generative stages of plant growth. Nitrogen efficiency is related to plant growth, production cost, and fertilizer residue. Azolla has the ability to increase nitrogen fixation from the atmosphere. Thus, Azolla cultivation in paddy field is one strategy for improving nitrogen fertilizer efficiency and increasing plant vegetative and generative growt...

ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1  N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...

A field experiment was conducted in 2007 and 2008 on a slightly acidic alfisol. Poultry manure (PM) was applied at 0, 5 t ha(-1), 10 t ha(-1), 15 t ha(-1), and 20 t ha(-1) in combination with SSP at 0, 15 kg P ha(-1), 30 kg P ha(-1), 45 kg P ha(-1), and 60 kg P ha(-1), which was replicated three times. The pH and organic C were significantly increased by the application of PM alone while availa...

The effect of aldicarb and fenamiphos on Tylenchulus semipenetrans population densities and on orange yield was investigated during a 3-year (1986-88) field trial in Italy. Rates were 10 and 20 kg a.i./ha as an early spring single application, 5 kg a.i./ha in spring and 5 kg after flowering, and 5 kg a.i. in spring followed by 2.5 kg/ha after flowering and 2.5 kg/ha in early autumn. Rates and t...

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...

Pre-seeding tillage of long-term no-till soil may alter soil quality by changing some properties, but the magnitude of change depends on soil type and climatic conditions. Effects of short-term (2 or 3 years) tillage (hereafter called reverse tillage [RT]) of land previously under long-term no-till (NT, 29 or 30 years), with straw management (straw removed [SRem] and straw retained [SRet]) and ...
