One of the ways to increase rice production is the use of new improved varieties that also benefited farmers. The assessment is carried out to the major technology components in the application of Integrated Crop Management (ICM). The objective of the assessment was to look at yield of new improved rice field compared to the commonly farmers planted rice varieties. The assessment was carried out on farmer's land in dry season I (April to July 2015) in Ranggo village, Pajo sub-district, Dompu district, West Nusa Tenggara involving farmers, with total land area of 1,0 ha. The assessment was prepared following randomized completely block design with 4 replications. A total of 5 (five) new improved varieties tested as treatment are Inpari-10, Inpari-16, Inpari-19, Inpari-22, Inpari-30 Ciherang Sub-1 and Cigeulis as check. In this study also apply the system of planting row jajar legowo 2:1 spacing (40 cm x 20 cm) x 10 cm. Plant fertilized with urea 200 kg/ ha and NPK 200 kg/ha. The parameters observed were: plant height, number of productive tillers, number of grains, weight of 1000 seeds, and yield. The results of assessment indicated that growth and yield components of new improved varieties of rice on all observed parameters showed significantly different results to rice varieties that commonly grown by farmers (Cigeulis variety). The hightest result were obtained on Inpari-30 Ciherang Sub-1 varieties (4,79 t/ha dry grain harvested/DGH), 10% higher than Cigeulis variety (4,35 t/ha DGH). Based on the preference of farmers, the variety of Inpari-30 Ciherang Sub-1 is favored because they have good taste of rice and higher production.

The spread of the Corona virus (Covid 19) is still developing with new variants, Indonesia is one of the countries that currently has not been able to overcome the pandemic. One of the ways to maintain the immune system is by maintaining nutritious food intake and consuming healthy foods. Deficiency of Zn in the body results in decreased endurance, productivity, and human quality of life. Zn deficiency is one of the causes of stunting. Inpari IR Nutri Zinc is biofortified rice with a zinc content of 34.51 ppm which plays a role in preventing stunting, helping to increase nutritional value while overcoming iron deficiency in the community. Based on the superiority of Inpari IR Nutri Zinc rice, it is necessary to study the productivity and suitability of agro-ecosystems on Lombok Island. The study was carried out in three locations, three growing seasons using Standard Operating Procedures (SOP) for IR Nutri Zinc Inpari Rice Cultivation. The three locations are Mataram District at MT I/2020, Gerung District MT II/2020 and Narmada District MT III/2020. The study was carried out using a Randomized Block Design (RBD) design in 3 locations, 3 growing seasons using the Standard Operating Procedure (SOP) for IR Nutri Zinc Inpari Rice Cultivation. The aim of the study was to determine the level of productivity consistency of the Inpari IR Nutri Zinc variety using the Standard Operating Procedure (SOP) for rice cultivation at the 3 locations. The planting of Inpari IR Nutri Zinc rice at each location and growing season was repeated 5 times. Parameters observed included agronomic growth and productivity. Data collection consists of secondary data (rainfall data) and primary data. For primary data carried out by direct observation in the field and interviews with implementing farmers and business actors. Inpari IR Nutri Zinc planted in 3 locations using standard operating procedures (SOP) for rice cultivation, showed higher productivity than the average yield of Inpari IR Nutri Zinc at the national level. The productivity of rice planted in the Mataram sub-district in MH 2020 was 7.63 t/ha. The planting of Inpari IR Nutri Zinc rice is suitable for planting in the rainy season, but can produce well in the dry season with water conditions or an average rainfall of at least 100 mm / growing season. Rice Inpari Nutri Zinc can and should be developed in West Nusa Tenggara Province, especially in paddy fields and districts where the stunting rate is still quite high in an effort to reduce and prevent stunting in West Nusa Tenggara.

Rice is a strategic food commodity in West Nusa Tenggara, until now it is still the 9th national food. West Lombok Regency is one of the central areas for developing rice production. Most of the farmers have not used new superior varieties of rice, especially the products of the IAARD and planting is still using the old method (tiles) or using irregular spacing. Several important factors that support production are the availability of seeds, fertilizers, medicines and labor. In general, the climatic conditions in the West Lombok region are very supportive of farming so that they can plant 2-3 times of rice a year. Land fertility and irrigation systems also support productivity, especially rice. The aim of this study is to determine the increase in rice productivity through the application of Jajar Legowo technology on the legowo types and varieties used as production components. The research was conducted in West Lombok Regency from April to July 2017, involving 33 respondents. The selection of respondents was carried out purposively on farmers who participated in the jarwo super program. The research method was carried out in a survey and the data were analyzed using descriptive statistics and linear equations. The variables are expressed in the production equation (Y), land area (X1), use of seeds (X2), urea (X3), NPK (X4), and labor (X5) on rice production.The results of the study, the production factors that had an effect on increasing productivity were the use of the number of seeds and the use of NPK fertilizer (P <0.05), while other factors such as the use of urea fertilizer, labor, varieties and types of legowo row did not have a significant effect. However, the type of jarwo 2: 1 is in analysis of the farming business better than other types of jarwo. Keywords: jarwo, rice, provitas, technology, urea. ABSTRAKPadi merupakan komoditas pangan strategis di Nusa Tenggara Barat, hingga saat ini masih menjadi lumbung pangan nasional ke-9. Kabupaten Lombok barat merupakan salah satu wilayah sentra pengembangan produksi padi. Sebagian besar petani belum menggunakan varietas unggul baru padi terutama produk Badan Litbang Pertanian dan tanam masih menggunakan cara lama (tegel) atau menggunakan jarak tanam yang tidak teratur. Beberapa faktor penting yang mendukung produksi yaitu ketersediaan benih, pupuk, obat – obatan serta tenaga kerja. Kondisi iklim di wilayah Lombok Barat secara umum sangat mendukung usaha tani sehingga dapat menanam 2 – 3 kali padi dalam setahun. Kesuburan lahan dan sistem pengairan turut menunjang produktivitas terutama padi. Kajian ini bertujuan untuk mengetahui peningkatan produktivitas padi melalui penerapan teknologi Jajar Legowo pada tipe legowo dan varietas yang digunakan sebagai komponen produksi. Penelitian dilaksanakan di Kabupaten Lombok Barat pada bulan April hingga bulan Juli tahun 2017 dengan melibatkan 33 orang responden.  Pemilihan responden dilakukan secara purposive pada petani yang mengikuti program jarwo super. Metode penelitian dilakukan secara survey dan data di analisa menggunakan statistik deskriptif serta persamaan linear. Variabel dinyatakan dalam persamaan produksi (Y), luas lahan (X1), penggunaan benih (X2), urea (X3), NPK (X4), dan tenaga kerja (X5) terhadap produksi padi. Hasil pengkajian menunjukkan bahwa faktor produksi yang memberikan pengaruh terhadap peningkatan poduktivitas yaitu penggunaan jumlah benih dan penggunaan pupuk NPK (P<0,05), sedangkan faktor lainnya seperti penggunaan pupuk urea, tenaga kerja, varietas dan tipe jajar legowo tidak memberikan pengaruh yang nyata. Namun, tipe jarwo 2:1 secara analisa usaha tani lebih baik dibandingkan tipe jarwo lainnya.
