“…Analysis of the agronomic trait SN of the cultivars in the experiment showed an increment of stalks for the cultivars SP79-1011 (51.13) and SP81-3250 (51.06) (TABLE 5). According to Oliveira et al (2007) and Andrade-Junior et al (2017), this may be due to the genetic characteristics of each variety and to results of edaphoclimatic conditions favorable to the interaction genotype versus environment, promoting higher performance of these genotypes. The lower NS of the cultivars RB867515, SP80-1842 and SP89-1115 could be also due to the influence of the herbicides, because even if they have not showed a significant effect, these cultivars may have had a physiologic disturb when submitted to the active ingredient reducing tillering, same results found by Procópio et al (2015) in their studies.…”

Chemical control is used to restrain the attack of weeds on cultivated crops in Brazil; however, the overuse of chemical products can cause damage to the crops. This study aimed to evaluate the phytotoxicity caused by pre-emergence (PRE) and post-emergence (POST) herbicides in sugarcane cultivars and their influence in agronomic and technological traits as well as to verify the existence of correlation between the herbicides effect and the measured traits. The experiment was carried out in a randomized complete block design with three replications, considering the factorial combination of five sugarcane cultivars and five control strategies, being four herbicides and one control. The sensitivity was evaluated at 30, 60 and 90 days after application, through a scale of intoxication symptoms. The herbicides with active ingredients diuron + hexazinone and ametryn presented more phytotoxicity effect; the cultivars RB867515 and SP81-3250 showed greater toxicity symptoms when exposed to the agrochemicals. Plant height was the only trait influenced by the herbicides. It was observed a significant correlation between the trait number of stems and phytotoxicity effect.

“…The use of drip irrigation can produce more giant sugarcane stalks and reduce the potential for water loss better than other watering techniques. The use of this drip irrigation system has the potential to be applied to oil palm nurseries because watering with drip irrigation can also reduce the amount of water that comes out with nutrients when watering plants in polybags [7].…”

Irrigation and fertilization are critical aspects in oil palm nurseries, so they need to be appropriately managed. Automatic drip irrigation technology has the advantage of saving water and labour usage. On the other hand, correctly applying slow-release fertilizer can fulfil the need for oil palm seedlings. The combination of drip irrigation and the application of slow-release NPK fertilizer can increase the effectiveness of maintaining oil palm seedlings. This study aims to obtain the best watering time and rate of slow-release NPK fertilizer on the growth and performance of oil palm seedlings in the main nursery. A field study was conducted since June 2021 until August 2021 at the Oil Palm Nursery Unit in Politeknik Negeri Lampung, Indonesia. The experiment arranges in split-plot design in randomized block design with three replications. The watering time is the main plot, and the slow-release NPK fertilizer rate is the subplot. The results showed that application of drip irrigation system with watering time in the morning, midday, and afternoon significantly affect stem diameter and number of leaves at three months after observation. The rate of 20 g plant-1 slow-release NPK fertilizer best-affected plant height, stem diameter, number of leaves, leaf area, and greenness index.

“…There is little published information on the growth, development and yield of sugarcane under high input conditions in these areas. Two experiments for assessing sugarcane yield under irrigation, carried out by Andrade Junior et al (2017) and Andrade Júnior et al (2012) in the state of Piauí (∼4 to 5°S), showed that high yields can be achieved in these regions.…”

Sugarcane in field plot experiments in tropical Brazil (Guadalupe, Piauí State, 6.6°S), produced very high yields under non-limiting water and nutrients. Mean stalk dry mass at 8, 11.5 and 15 months were 40, 51 and 70 t/ha respectively for six varieties and six planting dates. These yields were explained by high but not excessive temperatures allowing the canopy to close after 73 days on average. Substantial changes were required to enable the APSIM-Sugar model to simulate canopy and yield gain processes in Brazilian genotypes for the purpose of optimising variety, planting and harvest date options. A new modelling feature was proposed to deal with the observed growth slowdown when crop was about 7-8 months old and dry mass yields higher than 40 t/ha. All new parameters and features were validated with independent experiments as well as with the original dataset used for developing APSIM-Sugar. Future studies involving irrigation, yield gap analysis and climate change in environments where high yields are expected, should consider these modifications.
