Peanut Growth and Ginofor Formation on Boron and Phosphor Applications

Abstract

<p>Soil is an important factor in peanut cultivation as a nutrient provider. In recent years, peanut production has dwindled due to the decrease in soil fertility. Boron as a micronutrient can maximize peanut production through optimum viability of flowers and phosphor as essential nutrients for peanut to improve its pod filling. This study aims to examine the application of boron and phosphor growth and formation of peanut gynophore. The research was conducted from September 2017 to January 2018 in Sambirembe village, Magetan. The experiment uses randomized complete block design (RCBD) with the first factor applied on the dose of boron fertilizer (0, 1, 2 3 kg ha<sup>-1</sup>) and the second was on the dose of phosphor fertilizer (0, 75, 100, 150 kg ha<sup>-1</sup>), repeated 3 times. Boron application resulted in the highest plant height at the fourth week by 10.45%. The application of 1 kg ha<sup>-1</sup> boron without phosphorus (0 kg ha<sup>-1</sup>) yielded the highest gynophore formation, i.e. 42.</p>

Genetic Improvement of Local Red Peanut With Using Nuclear Technique (Multigamma Irradiation) for Obtaining Superior Variety

“…(1) Superior seeds are still relatively lacking which is the dominant factor in the low productivity of local red peanut; (2) poor drainage; (3) excess water plants at the beginning of growth in paddy fields in the rainy season and drought in the dry season at the end of growth (Rohmah et al, 2020); (4) lack of key nutrients such as N, P, K, and Ca (Sarwanidas et al, 2014;Rahman et al, 2019;Kaya, 2012;Nopitasari et al, 2020;Yudiwanti et al, 2018); (5) competition with weeds in the vegetative growth phase, rarely or late; (6) shallow soil processing so that root growth and pod development are not optimal; (7) the seeds used have low growth capacity (not superior); and, (8) disease attacks such as bacterial wilt disease and fungal wilt, rust and leaf spot, peanut stripe virus (PStV) striped virus, as well as rats, whitefly, leafworms, pod borer, and nematodes (Prayitno et al, 2018).…”

“…The number of seeds that did not grow in the selected sample was 100 seeds, both treatments were counted. Planting is done at the age of 7 days after planting; (8) Weed the plants and fertilize with NPK and Urea 2:1 so that the plants are free from weed disturbances and thrive (Rahman et al, 2019;Kaya, 2012;Novitasari et al, 2020); (9) Conduct a series of observations during plant growth including: pest-disease resistance, dry land adaptation, and plant selection. At the time of approaching the harvest period, another selection is carried out, measuring plant height, number of pods per tree, and number of seeds per pod.…”

Productivity and profitability of peanut at various land suitability in North Lombok Regency of Nusa Tenggara Barat Province

“…Improving peanut production can be obtained through technological improvements, such as using high yield potential varieties. Varieties are one of the factors that affect the productivity of peanuts (Munsaka, 2013;Katundu et al, 2014;Trustinah, 2015;Irmansyah et al, 2017;Siringo et al, 2018;Rahman et al, 2019).…”

Analysis of Peanut Farming in The 3rd Planting Season in Pemalang Ditrict, Indonesia

“…Nutrient management in inappropriate peanut lands is one of the causes of the low productivity of peanuts in Indonesia. According to [4], the lack of nutrients causes the process of filling the peanuts pods not full, even cipo (peanut pods that do not contain and whose bulkhead is unclear). According to [5], most peanut farmers in dry areas apply a small amount of fertilizer and sometimes only fertilize with one or two elements so that the plants do not get sufficient nutrients.…”
