“…In the present study, higher CGR and NAR in the same treatments indicated that more photoassimilates were produced (on account of applied N) and then translocated to aerial parts. These results also corroborated the earlier findings of Amanullah et al (2015) who recorded increases in grain yield components after integrating 120 kg of N ha −1 with farm manure compost in to a semiarid climate soil. In other research, increases in grain yield were reported for manure compost plus N fertilizer (Akhtar et al, 2011), implying improved N availability and management when manure was combined with N fertilizer (Arif et al, 2016b).…”

Declining soil fertility and crop yields are common in arid and semi–arid areas. Sustainable technologies that halt or reverse this trend are required to ensure food security. The use of compost for soil amendment should build soil resilience to drought. However, manure (which is a raw material in compost production) is used as a fuel in many semiarid regions of the world. To encourage farmers to change from using manure or composts as fuel to adopting them as soil additives, it will be necessary to demonstrate the production benefits associated with such additives. A 2‐yr field experiment was conducted in a semi‐arid (steppe) desert environment in Pakistan on sandy‐loamy soils. Poultry manure compost (PMC), pressmud compost (PrMC), and urea (U) were compared in a maize–maize (Zea mays L.) cropping system. The PMC and PrMC application increased soil organic carbon (SOC) and N as well as the soil's moisture content, but decreased the soil electrical conductivity (ECe) and pH after 2 yr. Replacing 25% of the U with PMC increased the mineral N and mean crop growth rate by 46%, the net assimilation rate by 30% and the yield by 219%, compared to the control. These results were comparable to applications of U alone and PMC with urea in a 25:75 application ratio. These results demonstrate that in semiarid regions, adding manure or compost as a soil additive improves the soil's yield potential. Core Ideas Less/no burning qualities manure can solve the conflict in using manure for energy. Compost can reverse soil fertility and maize yield decline in semiarid areas. Compost with urea at 25:75 can reduce 25% use of harmful mineral fertilizer.

“…The higher capacity of the plants to convert more photosynthates into the reproductive parts increases maize productivity. Increase in maize productivity with nitrogen fertilization was also reported by many workers (Malaiya et al, 2004; Amanullah et al, 2009a, 2015b). The increase in yield and yield components in the current study with N supply probably may be due to the increase in light interception (Amanullah et al, 2008) because of it higher LAI (Amanullah et al, 2014).…”

“…Our previous research work on maize and nitrogen management revealed that proper nitrogen rates and nitrogen timings (splits) management improve maize growth and development (Amanullah et al, 2007, 2008, 2009a,b; Amanullah and Shah, 2010), yield and yield components (Amanullah et al, 2009a), grain quality (Amanullah et al, 2010), and growers income (Amanullah et al, 2010) in the study area. In another study (Amanullah et al, 2015b), we noticed that the integrated use of nitrogen (120 or 150 kg N ha −1 ) along with compost (2 t ha −1 ) improved yield and yield components in maize under deep (45 cm) than shallow (15 cm) tillage system under semiarid climate.…”

“…Ammonium sulfate increases NUE, however, its higher cost make it less profitable N-fertilizer for the maize growers in Northwest Pakistan (Amanullah et al, 2015a). The decline in the price of AS could make it more profitable and most suitable N-fertilizer source under semiarid climates in terms of higher NUE (Amanullah, 2014), higher net returns (Amanullah et al, 2015b), and better seed quality (Khan, 2016). …”

Nitrogen Source and Rate Management Improve Maize Productivity of Smallholders under Semiarid Climates

Nitrogen is one of the most important factor affecting maize (Zea mays L.) yield and income of smallholders under semiarid climates. Field experiments were conducted to investigate the impact of different N-fertilizer sources [urea, calcium ammonium nitrate (CAN), and ammonium sulfate (AS)] and rates (50, 100, 150, and 200 kg ha−1) on umber of rows ear−1 (NOR ear−1), number of seeds row−1 (NOS row−1), number of seeds ear−1 (NOS ear−1), number of ears per 100 plants (NOEP 100 plants−1), grain yield plant−1, stover yield (kg ha−1), and shelling percentage (%) of maize genotypes “Local cultivars (Azam and Jalal) vs. hybrid (Pioneer-3025).” The experiment was conducted at the Agronomy Research Farm of the University of Agriculture Peshawar during summers of 2008 (year one) and 2010 (year two). The results revealed that the N treated (rest) plots (the average of all the experimental plots treated with N) had produced higher yield and yield components, and shelling percentage over N-control plots (plots where N was not applied). Application of nitrogen at the higher rate increased yield and yield components in maize (200 > 150 > 100 > 50 kg N ha−1). Application of AS and CAN had more beneficial impact on yield and yield components of maize as compared to urea (AS > CAN > urea). Hybrid maize (P-3025) produced significantly higher yield and yield components as well as higher shelling percentage than the two local cultivars (P-3025 > Jalal = Azam). Application of ammonium sulfate at the rate of 200 kg N ha−1 to hybrid maize was found most beneficial in terms of higher productivity and grower's income in the study area. For the two local cultivars, application of 150 kg N ha−1 was found more beneficial over 120 kg N ha−1 (recommended N rate) in terms of greater productivity and growers income.

“…The significance of compost in enhancing soil fertility for plant growth has been amply reported (Gul et al, 2016;Amanullah et al, 2015;Dada et al, 2014;Zai et al, 2008). D'Hose et al (2012) found that compost amendment considerably increased dry matter yields of different crops.…”

Intensive livestock production and poor agricultural management have resulted to excessive loading of soil with phosphorus (P), thereby contributing to environmental pollution and impairment of water quality. A study was carried out to determine the extractability and bioavailability of P in soils treated with poultry litter (PL) co-composted with sugarcane and cabbage wastes. The manure was applied based on total P contents at 200 and 400 kg P ha -1 , with maize (Zea mays L.) as the test crop. The co-composted PL increased maize growth relative to PL alone with the best growth occurring at the treatment rate of 400 kg P ha -1 . Maize biomass and available P in soil varied in the order PL co-composted with sugarcane waste and cabbage waste (%) 50 > 33 > 25 > 0. Phosphorus contents in maize shoot were higher in sandy clay than silt loam soil and its recovery was higher in soil treated with PL co-composted sugarcane waste than co-composted with cabbage waste. An amendment with co-composted PL increased the extractable P fractions and P availability in the soils. The P fractions in the postharvest soils varied in the order HCl-P > H 2 O-P > NaHCO 3 -P > NaOH-P and the fractions were significantly higher in the sandy clay than the silt loam soil. Also, the PL co-composted with sugarcane waste exhibited higher levels of P fractions in soils than co-composted with cabbage waste. Thus, co-composting poultry manure with crop wastes would better improve plant growth and P nutrition than sole-composted manure.
