In calcareous soils, wheat productivity is much lower due to improper nutrient management, especially phosphorus (P). Therefore, this study was conducted manage P availability from various organic (Control, FYM and Sugar cane straw applied at the rate of 10 ton ha−1) inorganic 100% rock phosphate (RP), 50% acidulated RP, single super (SSP) diammonium (DAP)) sources 90 kg P2O5 ha−1 in soil while using as test crop. When averaged across sources, SSP performed better emergence m−2 (126),...

As a multi-beneficial amendment, biochar is very useful to be applied for improving soil health and crop productivity. Therefore, this study was carried out assess the influence of wood mineral nitrogen (N), phosphorus (P) potassium (K) fertilisers viz, [(control; 100% NPK (120:90:60 kg ha−1); 75% + 5 tonne biochar; 50% 10 25% 15 20 ha−1)] on wheat yield properties under different management practices [(raised bed (more than 30 cm above ground) flat-bed)]. Split plot two factors randomised...

Management of nitrogen (N) fertilizer is a critical factor that can improve maize (Zea mays L.) production. On the other hand, high volatilization losses N also pollute air. A field experiment was established using silt clay soil to examine effect sulfur-coated urea and sulfur from gypsum on ammonia (NH

Nitrogen (N) and Phosphorus (P) deficiency is a major yield limiting factor across the globe their proper management plays vital role in optimizing crop yield. This field experiment was conducted to assess impact of soil plant nitrogen N P ratio on growth wheat (Triticum aestivum L.) alkaline calcareous soil. The study consisted various levels (0, 40, 80, 160 kg ha−1 as urea) phosphorus 30, 60, 90 P2O5 diammonium phosphate), carried out randomized complete block design (RCBD) with factorial...

A research study was established at the farm of University Agriculture, Peshawar during winter 2018–2019. Commercial biochars were given to experimental site from 2014 summer 2018 and received 0.95, 130 60 tons ha−1 biochar by various treatments viz., (Biochar1) BC1, (Biochar2) BC2, (Biochar3) BC3 (Biochar4) BC4, respectively. This piece work conducted within same find long-term influence on fertility soil, fixation N2, as well yie1d chickpea under a mung–chickpea cropping system. split plot...

Boron (B) deficiency is a widespread problem in alkaline soils which affects yield and quality of potato but often ignored by the growers. That's why, we compared impact different methods boron application (foliar spray, fertigation soil dressing) along with control on use efficiency (BUE), soils. (0.5 kg ha-1) applied as foliar spray had significantly increased plant height, tuber per plant, volume enhanced terms vitamin C, starch B content to other methods. Moreover, improved uptake it...

In calcareous soils, phosphorus (P) availability to plant is impaired due the formation of insoluble complexes with calcium and magnesium. Therefore, this study was executed compare P use efficiency (PUE) four different sources [rock phosphate (RP), acidulated rock (ARP), single super (SSP) di ammonium (DAP)] alone or pre-treated organic amendments (farm yard manure (FYM) enriched compost, simple compost humic acid (HA)) along control in maize crop under soils. All treatments irrespective...

An experiment was performed to investigate the effect of integrated phosphorus management with previously applied biochar at University Agriculture, Peshawar during 2018–2019. The treatments comprised two levels (10 tons ha−1 and no biochar) three sources P {Farmyard manure, poultry an inorganic source di-ammonium phosphate}. phosphorous were added in such a manner that 100, 75 50% received from organic remaining obtained vice versa @ 100 kg ha−1. This much needed for our conditions...

Using the water footprint (WF) approach to evaluate water-use efficiency in agricultural production is crucial for assessing sustainable use of resources and mitigating scarcity pollution. This study calculated blue, grey, green total footprints spring maize Northeast China 2019 2020 compared values at provincial municipal scales. In addition, this analyzed spatial variation drivers footprint. The results show that average were 1.78 m3kg−1 2.00 m3kg−1, out which grey contributed most,...
