“…The maximum dry mass weights of the vegetative parts (shoots and leaves), pods, and the total canopy at the end of the crop cycle, were 4.24, 4.07, and 7.61 Mg ha -1 , respectively (Figure 2). These values are higher than those found in earlier studies (Feitosa et al, 1993;Silva et al, 2017) and experiments conducted with cultivars other than IAC 503, used in this experiment.…”

“…Low dry mass accumulation was observed in the vegetative phase due to the shorter period (49 days) and smaller leaf area when compared to the reproductive phase of the crop (Figure 2). A steep increase in vegetative dry matter weight occurred at the beginning of the reproductive phase, from flowering (R1, 49 DAS) to grain appearance (R5, 89 DAS), followed by stabilization until physiological maturity (R7, 118 DAS), which is characteristic of the crop cycle, regardless of the cultivar, as observed by Coelho & Tella (1967), Feitosa et al (1993), and Silva et al (2017). Pod dry mass accumulation increased with grain appearance, in R5 to R7, following the pod addition and seed filling stages.…”

“…The highest nutrient absorption rate in peanut crop occurs between 60 and 100 days after sowing (DAS), and the rate of absorption and export of macronutrients by the crop has been shown to be superior at the recommended fertilization level (Feitosa et al, 1993;Silva et al, 2017).…”

Peanuts are one of the most produced legumes in the world; however, there is a lack of knowledge on their nutritional needs and the growth phases with greater demands; therefore research is required on the nutrient absorption rate of the crop. The objectives of this study were to determine the rates of absorption in the vegetative part and the pods, the accumulation of macronutrients in the vegetative part, pods, and in total, and the nutrient export to pods during the cycle of the peanut, cv Runner IAC 503, grown under full irrigation. The experiment was conducted at the Experimental Farm of the Faculty of Agrarian and Veterinary Sciences, Universidade Estadual Paulista, Jaboticabal campus, SP, Brazil, from March to August 2019 using a randomized block design, with evaluations of the macronutrient absorption rate and accumulation at 35, 49, 63, 77, 91, 105, 119, 133 and 147 days after sowing, with four replications. Higher nutritional demands of peanuts occurred between 63 and 105 days after sowing. Greater total accumulation of nutrients was reached at 118 DAS, with 234.8, 173.5, 79.0, 45.8, 23.4 and 18.8 kg ha-1 for N, K, Ca, Mg, P, and S, respectively. Exports of macronutrients contained in the pods totaled 138.8, 43.9, 14.6, 12.0, 7.3 and 5.4 kg ha-1 for N, K, P, Mg, S and Ca, respectively. Exported K in the harvest was two times greater than the applied amount at sowing, which followed the current Brazilian recommendation, causing possible depletion of this nutrient in the soil.

“…Older peanut cultivars, for example, IAC Caiapó, have the highest growth rate and nutrient accumulation between 100 and 110 DAE [22]. On the other hand, newer cultivars (e.g., IAC Runner, IAC 505 and IAC OL3) have the peak of growth rate and nutrient accumulation earlier, between 70 and 84 DAE.…”

The productive potential of new peanut cultivars has increased over the years in relation to old cultivars, especially when compared with ones with upright growth habit. Thus, the requirement for macronutrients for these new cultivars may also have increased, making the existing fertilizer recommendation tables obsolete, thus increasing the need for further studies measuring the real macronutrient requirements of these new peanut cultivars. Our study aimed to evaluate the growth patterns and the macronutrient absorption rate throughout the biological cycle of three modern runner peanut cultivars, as well as the potential for producing dry matter, pods, and kernels, and their respective macronutrient accumulations. The experimental design was a randomized complete block with split-plots and nine replications. The experimental plots consisted of three peanut cultivars (IAC Runner 886, IAC 505, and IAC OL3), and subplots consisted of nine plant samplings (14, 28, 42, 56, 70, 84, 105, 126, and 147 days after emergence (DAE)). Our results showed that modern peanut cultivars presented nutrient accumulation around 30 to 40 days earlier than older cultivars, as well as increasing the uptake by K and Ca. IAC 505 absorbed higher amounts of macronutrients and resulted in greater dry matter production compared with IAC OL3 and IAC Runner 886. Our study demonstrated that the most appropriate time for plants to find greater availability of nutrients in the soil is 70 to 84 DAE, in addition to highlighting the need for updates on nutritional recommendations for higher yields of modern peanut cultivars.

“…This was in line with the P and K levels in the soil which were high and low N (Table 4). The sufficient levels of N, P, K in groundnut shoots at the flowering (R1 phase) according to Jones et al (1991) are 3.50-4.50% of N, 0.20-0.35% of P, and 1.70-3.00% of K, and according to Singh et al (2010) are 3.14-3.54% of N, 0.31-0.38% of P, and 1.84-1.97% of K. In groundnuts, the highest absorption rate for N occurs during the R1-R4 phases, P during the R2-R4 phases, and K in the R4 phase (Silva et al, 2017 (Figure 2). The increase of CCI was in accordance with the decrease in soil EC.…”

Agriculture lands in coastal areas face the risk of increasing salinity due to the influence of sea water. Salinity poses complex problems for plants at all growth stages which are difficult to be addressed. Trichoderma is a microorganism known to promote plant growth and to induce plant tolerance to abiotic stresses including salinity. The research aimed to evaluate effective Trichoderma for improving groundnut growth and yield in a saline environment. The research was conducted on saline soil (EC >8 dS/m) at Gesikharjo Village, Palang Sub District, Tuban District from July to October 2019. Treatments were combinations between N and P fertilization, and four Trichoderma strains and these treatments were arranged in a randomized completely block design with six replicates, using Hypoma 1 groundnut cultivar. Soil fertility and salinity, growth, yield and yield components were recorded as observed parameters. The results showed that NP fertilization on high salinity soils (ECs of 8.80-15.91 dS/m) with low N and high P had no significant effect on all variables compared to those of N fertilization. Applications of Trichoderma increased plant height and minimized plant death as indicated by a higher percentage of plant population at harvest compared to that of without inoculation. Among the four Trichoderma strains, Trichoderma #3 and Trichoderma #4 showed more effective than the other two strains in improving plant growth based on the shoot dry weight at the R1 phase, plant height and percentage of plant population at harvest. The positive effect of Trichoderma #3 and #4 could be due to the ability to promote plant growth as well as to induce plant resistance against salinity stress. The results suggested that Trichoderma was effective to alleviate salinity stress on groundnut crops. This research was the first trial carried out in the field and therefore needs to be further investigated, including Trichoderma formulations and application techniques.
