ABSTRAKLahan kering di dataran rendah mempunyai iklim kering, sehingga curah hujan rendah,   ketersediaan air sangat terbatas, evaporasi dan transpirasi tinggi. Akibatnya tingkat kesuburan tanah rendah. Peningkatan hasil pipilan kering jagung tergantung pada masukan pupuk N dan P anorganik yang tinggi, tetapi hal ini tidak efisien dan menyebabkan ketidakseimbangan NPK pada tanah. Pupuk kalium berfungsi meningkatkan pertumbuhan dan hasil panen pipilan kering pada kondisi stres kelembaban di iklim kering. Penelitian dilakukan untuk mendapatkan kombinasi pupuk NPK dengan kalium dosis tinggi dan urea yang tepat untuk meningkatkan bobot pipilan kering jagung. Penelitian dilakukan di Desa Pakong, Kecamatan Pakong, Kabupaten Pamekasan, menggunakan pupuk NPK 15-10-19. Rancangan Acak Kelompok dengan 10 perlakuan dan 3 ulangan. Peubah yang diamati adalah tinggi tanaman, jumlah daun, panjang dan diameter tongkol, bobot 100 butir dan hasil jagung pipilan kering. Data dianalisis dengan ANOVA (Analisys of Variance) dilanjutkan DMRT pada α=5% dan analisis finansial menggunakan R/C ratio. Hasil penelitian menunjukkan bahwa pupuk NPK 15-10-19 berpengaruh nyata terhadap tinggi tanaman, panjang dan diameter tongkol, bobot 100 butir dan hasil jagung pipilan kering. Perlakuan pupuk 350 kg ha-1 Urea + 250 kg ha-1NPK 15-10-19 memberikan nilai R/C rasio yang lebih tinggi daripada perlakuan lainnya yaitu sebesar 2.14. Pupuk NPK 15-10-19 sebanyak 250 kg ha-1 + Urea 350 kg ha-1 merupakan usahatani yang paling menguntungkan dan mampu meningkatkan hasil jagung pipilan kering hingga 7.3 t ha-1. ABSTRACTDry-lowland has a dry climate, so rainfall is low, water availability is very limited, high evaporation and transpiration. That resulted in low fertility of soil. The increase in yield of dry shelled corn depend on high input of fertilizer N and P inorganic, but this way is not efficient and leads to an imbalance of NPK in soil. Potassium fertilizer  works to increase the growth and yields of dry shelled on the stress conditions of moisture in dry climate. This research conducted to get a combination of NPK fertilizer with high dose of potassium and urea to increase the weight of dry shelled corn. Research conducted in the Village of Pakong sub-District Pakong, Pamekasan, using NPK fertilizer 15-10-19. A Randomized block is designed with 10 treatments and 3 replications. Variables observed were plant height, number of leaves, length and diameter of cob, weight of 100 grains and yield of dry shelled corn. Data was  analyzed with ANOVA (Analysis of Variance) followed by DMRT at α=5%, and financial was analized using R/C ratio. The results showed that NPK fertilizer gave significant effect on plant height, length and diameter of cob, weight of 100 grains and yield of dry shelled corn. Treatment  of 350 kg ha-1 Urea + 250 kg ha-1 NPK 15-10-19 gave higher R/C ratio  than other treatment, which was 2.14. Application of NPK 15-10-19  + 250 kg ha-1 pottasium + 350 kg ha-1 urea  was the most profitable and it increased the yield of shelled corn dried up to 7.3 t ha-1.

Abstract Shallot production in Indonesia is still relatively low. This is due to the use of shallot bulbs that are not sterile and susceptible to disease. One way to increase the production of shallots is by using botanical seeds (True Shallot Seed). The research aimed to evaluate the growth and yield of two varieties of TSS with the application of NPK and Magnesium fertilizers. The treatment was arranged in a randomized block design with three factors. The first factor was varieties, which consisted of Sanren F1 and Lokananta varieties. The second factor was the application of magnesium, which consisted of without magnesium, 125, and 250 kg Mg ha−1. The third factor was the application of NPK, which consisted without NPK, 83.3, 166.6, and 250 kg NPK ha−1. The results showed that the effect of varieties, NPK fertilizer, and Mg were significant differences in the parameters of the number of leaves 7.0, and the number of bulbs plants 2.7 where sanren showed better results. While the effect of varieties, NPK, and Mg fertilizers was significant differences in the parameters of plant height 41.5 cm, the Lokananta varieties showed better yields.

The productivity of onion crop is poor due to inappropriate management and agronomic practices in Bangladesh. To figure out the effect of NPK fertilizer rate and spacing on growth parameters of onion a field experiment was conducted. The treatments were consisting of N fertilizer (0, 80,120 and 160 kg/ha), P fertilizer (0, 30, 50 and 70 kg/ha), k fertilizer (0, 50, 75 and 100 kg/ha) and three plant spacing viz., 10 cm × 10 cm, 15 cm × 10 cm and 20 cm × 10 cm. The experiment was designed in RCBD with three replications. Analysis of results indicates that the interaction effect of NPK rate and spacing shows significant (P<0.05) effect on plant height. Highest plant height was obtained in 20 cm × 10 cm spacing and application of 160 kg N/ha, 70 kg P/ha and 100 kg K/ha respectively. Moreover, maximum number of leaves was also found by plants spaced at 10cm and application of highest dose of fertilizers. Lowest plant height and number of leaves was attained in 10 cm × 10 cm spacing and without NPK fertilizer application. The total result analysis reveals that best growth performance of onion was found from 20 cm × 10 cm spacing combined with 160 kg N/ha, 70 kg P/ha and 100 kg K/ha fertilizer amendment. Res.
