“…A study by Sani et al [60] reported a significant increase by poultry manure on amaranths plant height and LAI at 20 and 40 days after emergence as compared to cattle manure and control on sandy loam soil. Alamzeb et al [61] reported that poultry manure significantly increased (p < 0.05) on wheat total dry matter at heading (561.5 g m −2 ) and physiological maturity (1165.2 g m −2 ) stages over cattle manure at heading (549.5 g m −2 ) and physiological maturity (1152.9 g m −2 ) stages. Usman [62] observed a significant increase by poultry manure (20 t ha −1 ) on tomato plant height at 2, 4, 6 and 8 weeks after transplanting as compared to cattle and goat manure.…”

A field study was conducted to assess the effect of tillage systems (TSs) and manure rates (MRs) on sunflower growth and yield at the University of Limpopo Experimental Farm (Syferkuil) which is on sandy loam soils and University of Venda Experimental Farm (UNIVEN) clayey soils, both located in Limpopo Province of South Africa for 2021/2022 and 2022/2023 cropping seasons. The experimental design was a split plot with three replications. The main plot was the tillage treatments: conventional (CON) and in-field rainwater harvesting (IRWH), while the subplots were the manure treatments: viz. poultry and cattle manures at rates of 20 and 35 t ha−10, plus a control (no manure application). The IRWH is a tillage technique that collects rainwater on a 2 m wide runoff strip into the 1 m wide basin where it infiltrates deep into the soil beyond the evaporation zone but is available for crop use. The results revealed that at Syferkuil IRWH had a significant increase (p < 0.05) on grain yield, head diameter, head dry matter and aboveground dry matter yield in both cropping seasons, whereas at UNIVEN, the significant increase was obtained on grain yield, head diameter, aboveground dry matter, plant height and stem girth during both cropping seasons. The effect of manure rate significantly increased with the application rate, with poultry manure at the highest rate of 35 t ha−1 significantly recording high mean values of grain yield, head diameter, head dry matter, aboveground dry matter, plant height and stem girth at both sites during the two cropping seasons. The increase in leaf area index and 100 seed weight by IRWH and manure rate application varied across the growing stages and cropping seasons with no consistent trend. At Syferkuil, TS and MR interaction was significant on head diameter and on aboveground dry matter at flowering stage in the first cropping season, whereas at UNIVEN, it was significant on head diameter in the first cropping season. Therefore, these results suggest that IRWH combined with poultry manure (35 t ha−1) can be adopted to improve sunflower crop yield under similar management and environmental conditions. In the absence of poultry manure, farmers may opt to use cattle manure at a rate of 35 t ha−1 for better improved yield.

“…The balance nutrients provision, especially N, increased the leaf area duration (Akhtar et al, 2019b), delayed the leaf senescence, and enhanced the dry matter (DM) production (Alamzeb et al, 2018). Dry matter accumulation is a promising indicator for optimum yield as the pre-anthesis biomass accumulation efficiently contributes to grain filling (Moe et al, 2019).…”

“…Plant photosynthetic capacity is a vital indicator for improving dry matter yield. Similarly, the balance of nutrient availability and enriched soil fertility via the OM enhanced the plant's photosynthetic capacity and, consequently, the dry matter accumulation (Alamzeb et al, 2018;Akhtar et al, 2019b). Bases of previous studies on growth and DM predominantly centered on stresses or simply recorded at heading and maturity (Alamzeb et al, 2018).…”

Adding organic matter to soil proved an efficient strategy for restoring soil fertility and improving crop dry matter – an indicator of yield potential. In this regard, evaluating the sources of organic matter (OM) (control, poultry manure [PM], farmyard manure [FYM], compost, and mungbean residues [MR]) to provide 120 kg N ha-1 and effective microbes (EM) (0, 100, 200, and 300 L ton-1 of OM) as 2% solution proceeded in field conditions during 2017–2019. The sowing of wheat seeds (cv. Pirsabak 2015) at 120 kg ha-1 took place in the field using RCB design with four replications. Results showed that PM/FYM had delayed the phenology and improved the biomass-related parameters, dry matter (DM) accumulation, and crop growth rate (CGR) more than compost and MR. However, the results were more pronounced when applied with 300 L EM ton-1 of OM from the PM. The maximum DM (55%) accumulation in plant parts occurred beyond 100 days after sowing (DAS). A marked increase in DM and CGR beyond 60 DAS and a reduction in CGR beyond 120 DAS appeared irrespective of treatments. In the case of EM, the 300 L ton-1 revealed superior in terms of growth, DM accumulation, CGR, and delayed phenology. Structural equation modeling suggested that DM production gained a direct effect from crop phenology (46.1%) and crop stand (30.4%) but no indirect effect from crop growth (24.8%). In conclusion, the 300 L EM ton-1 of OM applied to PM or FYM had improved the crop stand, development, and DM production in wheat.

“…However, it is difficult to properly manage N in cotton due to indeterminate growth behavior (Chen et al., 2019) resulting in uneven growth with insufficient or excessive N application (Rosolem & Mikkelsen, 1989). It was observed that inadequate application of N resulted in poor growth and a 50% reduction in yield (J. Iqbal et al., 2015; Alamzeb, Anwar, Iqbal, Meizhen, et al., 2018). Thus, to sustain optimum crop growth and productivity, a huge amount of N fertilizers are used (Sarasketa et al., 2014; Anwar, 2017) and their application may increase in the future by threefold (Good et al., 2004).…”

A larger root system enhanced biomass accumulation, and high nitrogen (N) metabolism is an effective mechanism of plants in response to low N stress. How cotton plants balance N metabolism and enhanced biomass accumulation to support larger root systems under low N stress remains to be elucidated. This study deals with the changes in root development due to biomass accumulation and N metabolism in contrasting N‐efficient cotton genotypes (CCRI‐69, N‐efficient, and XLZ‐30, N‐inefficient) under low (0.2 mM) and normal (2 mM) N concentrations. The results showed that genotype CCRI‐69 produced a larger root system, high biomass accumulation, and N metabolism than XLZ‐30. The flourishing root system of CCRI‐69 was due to more allocation of sugars from shoot to root, especially under low N concentrations, to support efficient N uptake followed by high N metabolism and N use efficiency (NUE). In addition, CCRI‐69 produced more dry biomass, high photosynthetic activity, N‐related enzymatic activities, N uptake, and utilization under normal N concentration compared with XLZ‐30. Based on multivariate analysis, root morphological traits, sugar contents, and N‐assimilating enzymatic activities might be considered the key traits contributing to NUE and can also be used as potential indicators for genotypic evaluation. In the future, high N metabolism and allocation of more sugars under low N concentration could be studied at a molecular level to better understand the underlying molecular mechanism of NUE in cotton.
