“…Analisis sidik lintas merupakan suatu metode statistika yang digunakan untuk menganalisis pengaruh variabel bebas terhadap variabel tidak bebas (Tiecher et al 2018). Menurut Fallahi et al (2017), analisis path atau analisis sidik lintas bertujuan untuk mengetahui variabel Karakter yang dimasukkan dalam analisis regresi bertahap adalah karakter yang memiliki korelasi nyata dengan hasil biji.…”

Assembly and utilization of hybrid maize that tolerant low N is one of technology application to resolve limitation of N for hybrid maize in the suboptimal field. The objectives of this research were to select the genotype of hybrid maize that tolerant low N and determine the plant characters to be used as selecting indicator for hybrid maize that tolerant low N. Research conducted at the Experimental Farm of Indonesian Cereal Research Institute, Maros from June-November 2014. This research was arranged in split plot design with three replication. The main plot was the dose of nitrogen fertilizer that consisted of 0 kg N/ha (without N fertilization), 100 kg N/ha (low dose of N) dan 200 kg N/ha (normal dose of N). The subplot was 60 hybrid maize genotypes including control varieties P-27, NK-33, Bisi-2, and Bima-3. The results showed that reduction of 67,13% grain yield was observed in the hybrid maize without N fertilization and reduction of 33,08% was observed in hybrid maize with low N fertilization. Based on tolerance index in low N stress, the varieties HLN03, HLN17, HLN18, HLN24, HLN25, HLN32, HLN35, HLN39, HLN46, and HLN47 were grouped into hybrid maize genotype that tolerant low N with grain yield range 8,37 to 10,02 t/ha, and the highest grain yield was resulted from genotype HLN 32 (10,02 t/ha). Stepwise regression analysis demonstrated that some characters, those are leaf width, male flowering age, leaf aging, percentage of abnormal cobs, cob length, cob diameter, and kernel yields can be used as indicators for hybrid maize that tolerant low N.

“…At all study sites, contents of P in the HCl-P i pool were low than in other P pools, as determined from the Hedley's procedure. The HCl-P i pool is related to Ca-P forms which are expected to be very low in weathered soils (Tiecher et al, 2018), such as those in the present study. The HCl-P i contents at 0-10 cm soil depths were 207 and 52% higher in the V1 and V2 areas than in the forested area, respectively (Figure 2).…”

The objective of this work was to evaluate changes in phosphorus fractions in a Humic Cambisol cultivated with vineyards, after 62 years of additional fertilization with poultry litter. Soil samples were collected from two vineyards (V1 and V2) and a forested area adjacent to them. A total of 1,365 and 910 kg ha-1 P were applied to V1 and V2, respectively, throughout the past 62 years. Samples were collected at 0-10, 10-20, 20-30, and 30-40-cm soil depths for the analysis of soil physicochemical properties. The addition of poultry litter to the soil of the vineyards increased the contents of inorganic P (Pi) in all fractions, except in the residual fraction (residual-P), mainly at the 0-10-cm soil depth, in comparison with the forested area. The addition of poultry litter as fertilizer does not affect the organic P (Po) stock in the Humic Cambisol, it only increases the Pi contents of the soil.

“…According to Tiecher et al (2018), the increase in the adoption period for no-tillage promotes the activity of the soil microbiota, directly influencing the biological reactions of the P cycle, with an increase in Po, which, when mineralized, buffers the PiAER (P available for Biomass). Thus, in soils with low levels of available P and high capacity for fixing this nutrient, as is the case of Oxisols in the Amazon, the adoption of no-tillage is an excellent alternative to circumvent issues related to P retention, applied via mineral fertilization.…”

“…According to studies carried out by Souza et al (2007), the increase in PoHid0.1 contents with the time of adoption of no-tillage is very important in the P dynamics as the PoHid0.1 fraction can behave as a reservoir through Po mineralization by acid phosphatases, with a consequent buffering of the most available fractions of P (Novais et al, 2007;Tiecher et al, 2018).…”

Phosphorus (P) deficiency is one of the main factors that limits productivity in Brazilian soils. However, soil management under no-tillage system (NT) may alter the availability of P in the soil. The objective of this study was to evaluate the dynamics of P fractions in a dystrophic Yellow Latosol, cropped under no-tillage for a long period of time in the Amazon Biome. The study was conducted on a farm located in the municipality of Paragominas, southeastern Pará. This experiment evaluated plots cultivated in plots at nine (NT9), 11 (NT11) and 13 (NT13) years of no-tillage system adoption, in one plot under conventional cultivation system (CS) and a surrounding area under native forest (NF) at depths of 0-10, 10-20, 20-30 and 30-40 cm. The soil samples were subjected to P chemical fractionation to determine the different fractions. The soil management systems showed differential capacity of P accumulation. In the areas under no-tillage, P is accumulated in the toplayer and drastically reduced with depth, while in CS, this reduction is less pronounced. In the 0-20 cm depth layer during the adopted period of the no-tillage system, it was observed an increase in the content of inorganic phosphorus extracted by resin and 0.5 M NaHCO3 (PiAER and PiBIC) and organic phosphorus extracted by 0.5 M NaHCO3 (PoBIC), fractions considered as available for Biomass. Regardless of the year of adoption, the no-tillage system was superior to CS and NF. This was also observed for the inorganic and organic fractions extracted by NaOH 0.1M (PiHid-0.1 and PoHid-0.1)and inorganic fraction extracted by HCl 1M (PiHCl).
