Field experiments were conducted to evaluate plant population and N-fertilizer effects on yield and yield components of maize (Zea mays L.). Three levels of plant populations (53000, 66000, and 800,000 plants ha⁻¹ corresponding to spacings of 75 × 25, 60 × 25, and 50 × 25 cm) and 4 doses of N (100, 140, 180, and 220 kg ha⁻¹) were the treatment variables. Results revealed that plant growth, ligh...

in order to study the competition effects of redroot pigweed (amaranthus retroflexus) and millet (panicum miliaceum) on maize performance under different rates of n fertilizer, a field experiment was conducted in 2009 in the research fields of tarbiat modares university in tehran as a randomized complete block design with factorial arrangement of treatments and three replications. accordingly, ...

Safflower (Carthamus tinctorius L.) is an oil-crop suitable for semi-arid agriculture, but its physiological response to agronomic inputs has yet to be fully evaluated. The effect of fertiliser on the physiology and production of Safflower grown in pots filled with standard grade perlite inside a semi-controlled glass house was studied. Plants were initially irrigated with 20-100 ml standard hy...

The performance of canola (Brassica napus L.) was evaluated using various nitrogen levels and shoots cutting at New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during Rabi 2012-13. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement having four replications each. Nitrogen levels @ 0, 50, 75 and 100 kg ha were allotted to...

A field experiment was carried out during 2008/2009 and 2009/2010 seasons in Agriculture farm, Sebha University, Libya to study the response of some safflower varieties(S , Giza and Dem ) to fertilization by 350 1 137 farm yard manure (FYM) combination with mineral nitrogen fertilizers (0 ton FYM+105 kg N, 1.538 ton FYM +95kgN, 3.076 ton FYM +85 kg N, 4.614 ton FYM + 75 kg N, 6.152 ton FYM + 65...

An accurate and management sensitive simulation model for tile-drained Midwestern soils is needed to optimize the use of agricultural management practices (e.g., winter cover crops) to reduce nitrate leaching without adversely affecting corn yield. Our objectives were to enhance the Agricultural Production Systems Simulator (APSIM) for tile drainage, test the modified model for several manageme...

A field experiment was conducted to determine the response of different doses of N and P2O5 on the growth and flower quality of gladiolus at farmer field district Quetta during the summer season 2008. Six treatments were included in the trial viz; T1 (125+100); T2 (125+200); T3 (150+100); T4 (150+200); T5 (175+100) and T6 (175+200) NP kg/ha were tested in four replicated randomized complete blo...

A field experiment was conducted during two consecutive Kharif seasons, 2021 and 2022 at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture Technology, Kumarganj Ayodhya (Uttar Pradesh, India) to assess the effect crop establishment methods nutrient management on growth indices yield rice (Oryza sativa L.). The in split plot design which comprised four methods. There are: M...

A study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (Ocimum basilicum L.). The research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. The experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

An experiment was conducted in the Experimental Farm Garden, at Assam Agricultural University, Jorhat to see influence of manure and fertilizers on growth yield Pipali (Piper longum) conditions. Result revealed that maximum (576.25kg/ha dry) obtained when applied @ 175:75:75 kg ha-1(NPK) + FYM 10 ha-1 Neem cake 5q minimum (318.67 Kg/ha only field. Hence, we conclude long pepper is an organic ma...
