“…According to Aryadi et al (2013), defoliation carried out after the vegetative growth process of photosynthates is more widely used for the process of filling cobs rather than plant growth. The treatment of adding doses of SP-36 fertilizer showed significantly different results on the parameters of plant height, stem diameter, plant root weight, fresh cob weight, and cob dry weight but showed unreal different results on the parameters of root length, cob diameter, cob length, dry pile weight and weight of 100 seeds.…”

The high demand for Maize encourages various agricultural innovations. The study aims to examine the effect of defoliation and P fertilizer application on the growth and production of the Madura 3 Maize variety which is grown in the close cropping system. This study used a randomized block design consisting of two factors with three replications. The parameters observed were stem diameter, root weight, cob fresh weight, cob dry weight, dry seed weight, and 100 seed weight. The results showed that there was a significant interaction between the defoliation factor and the dose of SP-36 on cob diameter, where the highest diameter (4,75 cm) was found in the combination of non-defoliation and SP-36 150 kg.ha-1. Overall, the non-defoliation of an SP-36 of 250 kg.ha-1 showed the best result on Maize growth and production. The addition of the dose of SP-36 also needs to pay attention to the needs of plants.

“…Defoliasi bertujuan untuk mengurangi persaingan internal dalam pemanfaatan asimilat dan memaksimalkan asimilat yang akan ditranslokasikan ke biji Aryadi et al, (2013). Posisi dan waktu defoliasi yang tepat dapat meningkatkan hasil panen pada tanaman jagung.…”

“…Translokasi asimilat lebih fokus organ generatif. Hal ini didukung oleh hasil penelitian (Aryadi et al, 2013;Affandi et al, 2014) yang menunjukkan bahwa defoliasi tidak berpengaruh nyata terhadap tinggi tanaman jagung. Pada Tabel 3 nampak bahwa tanaman tertinggi terdapat pada perlakuan P3 (208,3 cm) dan tidak berbeda nyata dengan P1 dan P2, sedangkan pada perlakuan D2 menunjukkan tinggi tanaman paling tinggi yaitu 205,1 cm.…”

Upaya yang dapat dilakukan dalam peningkatan produksi jagung dapat dilakukan dengan penggunaan varietas unggul, defoliasi dan pemupukan yang berimbang. Penelitian ini bertujuan untuk mengetahui pengaruh pemupukan lewat daun (foliar) dan pemangkasan daun tanaman jagung (defoliasi) terhadap pertumbuhan dan hasil jagung hibrida NASA 29. Penelitian ini dilaksanakan di Kebun Percobaan Samboja, Desa Bukit Raya, Kec. Samboja, Kutai Kartanegara, Kalimantan Timur, pada bulan April-Juli 2020. Bahan tanam yang digunakan adalah jagung hibrida NASA 29, pupuk KNO3, Gandasil D dan MKP. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan 3 (tiga) ulangan. Faktor pertama jenis pupuk yang diaplikasikan lewat daun (foliar) yang terdiri dari 3 taraf yaitu P1 (pupuk gandasil), P2 (pupuk MKP) dan P3 (pupuk Rosasol). Faktor kedua adalah waktu defoliasi yang terdiri dari 3 taraf yaitu D1 (75 HST), D2 (82 HST) dan D3 (90 HST). Data hasil pengamatan dianalisa dengan analisis ragam dengan uji F pada α = 5%. Bila terdapat beda nyata, dilanjutkan dengan uji BNJ pada α = 5%. Hasil penelitian menunjukkan perlakuan jenis pupuk lewat daun dan defoliasi beserta interaksi tidak memberikan pengaruh nyata terhadap variabel tinggi tanaman, panjang dan lebar daun, diameter batang, tinggi letak tongkol, panjang tongkol dan diameter tongkol. Perlakuan pupuk P3 dan defoliasi D2 memberikan hasil terbaik pada berat tongkol dan berat biji kering pipil.

“…Menurut Bahctiar et al, (2016) karakteristik agronomis varietas Nasa 29 berupa tinggi tanaman, besar dan panjang tongkol, pengisian biji, kekokohan batang, dan potensi hasil sebanding dengan varietas hibrida komersial yang ditanam petani. D e f o l i a s i b e r t u j u a n u n t u k m e n g u r a n g i persaingan internal dalam pemanfaatan asimilat dan memaksimalkan asimilat yang akan ditranslokasikan ke biji (Aryadi et al, 2013). Posisi dan waktu defoliasi yang tepat dapat meningkatkan hasil panen pada tanaman jagung.…”

This study aims to determine the effect of foliar fertilization and corn leaf trimming (defoliation) on the growth and yield of hybrid corn NASA 29. This research was conducted at the Samboja Experimental Garden, Bukit Raya Village, Kec. Samboja, Kutai Kartanegara, East Kalimantan, in April-July 2020. The planting material used was the NASA 29 hybrid corn variety, KNO3 fertilizer, Gandasil D fertilizer, MKP fertilizer. This study used a factorial randomized block design (3 X 3) with 3 (three) replications. The first factor was the type of fertilizer that was applied through the leaves (foliar) which consisted of 3 levels, namely P1 (fertilizer gandasil), P2 (fertilizer MKP), and P3 (fertilizer Rosasol) with a dose of 10 grams/liter each given at the age of 65 DAS. The second factor was defoliation time which consisted of 3 levels, namely D1 (75 days after planting), D2 (defoliation at 82 days after planting), and D3 (defoliation at 90 days after planting). The observed data were analyzed by means of the analysis of variance with the F test at α 5%. if there is a significant difference, it is followed by the Honestly Significant Difference (HSD) test at α 5%. The results showed that the treatment of the type of fertilizer through the leaves and defoliation along with the interactions had no significant effect on the variables of plant height, ear length, and ear diameter, while the treatment of fertilizers by leaf and defoliation and their interactions had no significant effect on the variables of plant height, stem diameter. ear length and ear diameter. P3 fertilizer treatment and defoliation at the age of 82 days after planting (D2) gave the best results on the variable ear weight and dry seed weight.
