The national average corn production is only 5 — 6 tons per hectare. Again, farmers in Lamongan Regency, East Java province, received 5.8 tonnes per hectare. However, now production soared to 11.8 tonnes per hectare. "The target is 12 tons per hectare in all areas of Lamongan," said the regent of Lamongan, H. Fadeli, S.H., M.M. He tried planting corn on a land area of 100 hectares in Solokuro, Lamongan regency. Corn production soars because Fadeli grows intensively. Bupati Lamongan, H. Fadeli, S.H., M.M. (berkemeja biru), serius mengembangkan jagung di Kabupaten Lamongan.
The Regent of Lamongan, H. Fadeli, S.H., M.M. (blue spell), seriously developed maize in Lamongan regency.
"We call this the modern corn farming, the corn farming intensive since the processing of soil to post-harvest," Regent said the birth of July 16, 1955. Conventional corn cultivation in Lamongan is usually without soil. In the trial Fadeli cultivate the ground. According to researchers from the Center for Agricultural Technology Studies East Java (BPTP JATIM) Prof. Dr. Ir. Mohammad Cholil Mahfud, M.S., the cultivation of corn modernly cultivate the soil with a tractor up to a depth of 20 cm.
Jajar Legowo
The cultivation process begins with the selection of high-quality corn seeds, hybrid corn that is adaptive to the environment in Lamongan. "One of his resources grew above 90%," he said. According to Cholil, there are many superior varieties circulating in Lamongan. "Our test results there are more than 15 varieties that corn farmers use in Lamongan. However, only 6 — 8 varieties that potential results are more than 10 tons per hectare, "Cholil said.Fadeli gives organic fertilizer or animal dung 1.5 tons per hectare as the basic fertilization,. "The goal is to be loose soil, roots grow perfectly so that the plant also grows optimally," Ujar Cholil. What is not less important is the use of the model planting Legowo Jajar with planting distance 120 cm x 60 cm x 12.5 cm One seed per planting hole. Another option of the Legowo Jajar is planted 90 cm x 40 cm x 40 cm with 2 seeds per hole.
According to Cholil corn farmer in Lamongan generally use conventional planting pattern with planting distance 75 cm x 75 cm x 20 cm with 1 seed per hole. The planting pattern is too loose, so the plant population is less maximum. "With a conventional cropping pattern,a the plant population is only about 64,000 plants per hectare, whereas dengan withplanting distance 90 cm x 40 cm x 40 cm crop population to 82,000 plants per hectare," said Cholil.
Agricultural machinery use increase the cost of production and increase farmers ' income.
Fertilization should also be intensive and in accordance with the needs of plants. "We have been doing research on fertilizer needs in Lamongan," said alumnus Of UNiversitas Putera Malaysia. Total fertilizer reaches 300 — 500 kg Urea plus 200 — 400 kg Phonska (15:15:15) per hectare. Fertilizer 2 — 3 times the way it is assigned. The first fertilization when the plant is 7 — 10 days after planting (HST). Fadeli gives 400 kg of phonska fertilizer and 20% Urea equivalent to 100 kg.
As for the second fertilization when Corn is 25 — 30 days. Fadeli gives HST 40% Urea or 200 kg. When Zea Mays was 40 — 45 days old, he again gave 200 kg of Urea. "Aquaculture corn conventional use of the plant under the figure so that the crop is deficient in nutrients," said Cholil, a member of the Indonesian Fitopatology Association. In addition Fadeli also pay attention to the way fertilizer.
"So far many farmers are cultivating its guard by spreading on the ground. In fact, the way it makes 40% of the fertilizer evaporates, "said Prof. Cholil. The right way by assigning new ground and then inserting fertilizer into the hole of the land. "By assigning soil when fertilization, corn productivity increased by 29% compared with no ditugal," said the professor who produced 67 more scientific writings.
The application of modern corn cultivation technology does increase the cost of production. "Although production costs increase but the profit of farmers increased quintupled," said according to the head of the horticultural and plantation food crops, Lamongan regency, Ir. Aris Setiadi, M.M. The cost of intensive corn production increased to Rp 14.717.500 per ha. While the cost of production of other farmers who planted corn conventionally only Rp 11.875.000 per hectare per season.

The increase in production costs was covered by planters ' profits. When harvesting on January 2017, the price of corn in Lamongan Rp 3.400 per kg. Fadeli is able to pick 10.8 tons of corn per hectare or 5 tons more are compared to conventional farmers. If farmers ' income increased from Rp 10.225.000 to Rp 21.492.500 per hectare. "R/C ratio reaches 2.5 while conventional corn farming is 1.9 alone," said Aris.
Expanded 12 sub-districts
Production costs increased by 23.9% while yields increased by 63.8%, and farmers ' revenue increased by 110.1%. Seeing the success of the program, Fadeli ready to work further by testing in 12 sub-districts. Each district has corn cultivated in 10 hectares of land with the same technology. The harvest on April 2017 was also encouraging, the average productivity of translucent 10 tons per hectare.Even in Solokuro the previous plantings averaged 10.8 tonnes per hectare up to 11.3 tonnes per hectare. "What a remarkable achievement in Lamongan," Fadeli said. Fadeli spirit was increasingly higher to increase the production of maize Lamongan. "The Regent will provide seed assistance to corn farmers for a land area of 1,200 hectares. The target of the planting season October 2017, "said Cholil.
The application of corn cultivation technology was Fadeli visit to the World Corn Center in Iowa, USA, in April 2016. At that time, he attended the invitation of the Embassy of the Republic of Indonesia (Indonesian Embassy) in the United States to attend a farming exhibition titled Progess Show Farm. "In the United States many agricultural technologies, especially corn that can be applied in Indonesia, including in Lamongan," said Fadeli.
Please Mafhum, the potential of Lamongan Regency as the center of Corn is promising. "Of Lamongan's total area of 1,812 km², 60% of farmland including farms and 70 — 75% of Lamongan's residents are farmers," Fadeli said. Appropriate if the productivity of corn Lamongan in 2016 reaches 372,162 tons per year. However, unfortunately the average productivity is still not maximal. (Bondan Setyawan)
