A series of experiments was carried out at Students Farm, Sindh Agriculture University, Tandojam to evaluate the effect of NPK, micronutrients and N-placement on the growth and yield of sunflower during 2005-2006. The sunflower cv. HO-1 was studied under 7 different NPK levels and placement methods (0-0-0 NPK kg ha, 6030-30 NPK kg ha (N as broadcast), 60-30-30 NPK kg ha (N as fertigation), 90-4...
Short growing season restricts production of standard-sized fruit trees in nurseries at cold regions. Enhancing plant growth by optimizing program of mineral nutrition may solve the problem. This study evaluated efficiency of fertilizers [urea, sulfur coated urea (SCU), or foliar applications of a NPK compound fertilizer] for optimizing the growth of seedling rootstocks and grafted young almond...
to investigate the effects of intercropping of basil (ocimum basiilicum l.) and cowpea (vigna unguiculata l.), different levels of nitrogen fertilizers on basil and cowpea yield, an experiment was carried out during 2010 and 2011. experimental factor were included weed treatment (weeding and unweeding), three levels of nitrogen fertilizer (0, 50 and 100 kg ha-1), different planting ratio, (p1: ...
Nitrogen fertilizer application for corn (Zea mays L.) based on available N of soil can decrease the need to N fertilizer and, consequently, reduce the risk of environmental pollution, especially that of groundwater and drinking water. The objectives of this study were i) determining soil N03-N critical level at 4 to 6 leaf stage, ii) to study soil nitrate distribution, iii) determining N rate ...
Abstract This study examined the effect of Zeolite soil amendment on performance (growth and yield) sweet corn.The experiment was carried out in rice fields KP. Mojosari, Mojosari District, Mojokerto Regency MK II 2021 (April to September 2021), with 10 fertilization treatments which are combination best improver dose corn plants, including treatment A (control), B (Urea 200 kg/ha, ZA 100 NPK 2...

Saffron production will be increased in arid regions by providing sufficient water through appropriate agronomic strategies. Therefore, in this investigation the impact of different rates of super absorbent polymer (SAP) including 0,10, 20, 30, 40 and 50 kg ha-1 was studied on saffron flowering traits during two growth cycles. Results showed that the influence of experimental factor was signifi...
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...
اطلاع از تغییرات زمانی میزان تولید رواناب و رسوب در طول فصل زراعی نهتنها در اتخاذ نوع و نحوه انجام کارهای حفاظتی مفید است بلکه در برآورد مدلهای فرسایش خاک و رواناب کاربرد دارد. تحقیق حاضر با هدف بررسی تغییرات زمانی مقدار تولید رواناب و رسوب در طول فصل رشد گیاه نخود با تراکمهای مختلف کشت تحت شرایط دیم در ایستگاه تحقیقات حفاظت خاک تیکمهداش در کرتهای فرسایشی اجرا شد. بدین منظور تحقیقی در قالب...
