ABSTRAK<br />Kendala utama dalam produksi jahe (Zingiber officinale, Rosc.)<br />adalah kurang tersedianya benih yang bermutu dan komponen teknologi<br />pemupukan yang tepat. Upaya pemilihan bahan tanaman yang bermutu<br />serta penggunaan kasting telah dilakukan melalui penelitian yang<br />bertujuan untuk memberikan petunjuk tentang kondisi optimum benih<br />berdasarkan posisi bagian rimpang (umur fisiologis) yang dapat<br />meningkatkan produktivitas tanaman serta dosis optimum dari penggunaan<br />kasting. Percobaan ini dilaksanakan di Instalasi Penelitian Cimanggu,<br />Balai Penelitian Tanaman Rempah dan Obat, Bogor, pada bulan Agustus<br />1996 sampai Januari 1997 yang merupakan percobaan pot. Bahan tanam<br />berasal dari jahe putih besar yang dipanen pada umur 10 bulan. Rancangan<br />yang digunakan adalah rancangan acak kelompok yang disusun secara<br />faktorial, 3 ulangan. Faktor pertama terdiri atas perlakuan umur fisiologis<br />posisi bagian rimpang : bagian rimpang ke II, III dan IV dan faktor kedua<br />terdiri atas takaran pupuk kasting : 0; 0,25; 0,50; 0,75; 1,0 kg/tanaman/pot.<br />Setiap perlakuan dalam satu ulangan terdiri atas 6 contoh tanaman. Hasil<br />penelitian menunjukkan bahwa pemberian kasting meningkatkan tinggi<br />tanaman, jumlah anakan dan jumlah daun, bobot segar rimpang, bobot<br />kering tanaman (daun, batang, akar dan rimpang), produksi pati, serapan<br />hara N, P, K dan C-organik. Penggunaan benih pada posisi bagian rimpang<br />ke II, III dan IV yang dikombinasikan dengan kasting 0,50 kg/tanaman<br />dapat meningkatkan bobot kering rimpang masing-masing 62,17g, 59,49g<br />dan 58,65 g/tanaman dengan kadar pati 40,71%, 34,36% dan 39,57%.<br />Kata kunci : Jahe,  Zingiber  officinale,  pupuk  kasting,  benih,<br />pertumbuhan, produksi, mutu, Jawa Barat<br />ABSTRACT<br />The effect of casting fertilizer and types of seeds on<br />growth, yield and quality of young ginger<br />The most important constrains in ginger (Zingiber officinale Rose)<br />production are lack of good quality seeds and components of fertilizer<br />technology. The research was conducted to obtain the optimum condition<br />for ginger production from different parts of rhizome (physiological age)<br />and optimum dosage of casting. The research was conducted in Cimanggu<br />Research Instalation, Indonesian Spice and Medicinal Crops Research<br />Institute (ISMECRI) Bogor from August 1996 until January 1997 in pot<br />experiment which was arranged in completely randomized design with 2<br />factors and 3 replications. The first factor was 3 parts of rhizome position<br />(secondary, tertiary and quarter rhizomes) while the second factor was<br />dosage of casting fertilizer (0; 0.25; 0.50; 0.75; 1.0 kg/plant). The results<br />of the research indicated that the use of casting fertilizer could improve the<br />height of plant, number of leaves, number of tillers, fresh weight and dry<br />weight of rhizome, dry weight of leaves, dry weight of stem and dry<br />weight of root. Casting application improved starch content and nutrient<br />absorbtion of N, P, K and organic carbon. Combination treatment of<br />secondary, tertiary and quarter rhizomes combined with application of<br />casting 0.50 kg/plant, improved dry weight of rhizome 62.17 g, 59.49 g<br />and 58.65 g/plant and starch content of rhizome 40.71%, 34.36% and<br />39.57% respectively.<br />Key words : Zinger, Zingiber officinale, casting fertilizer seeds, growth,<br />yield, quality, West Java

Water pumping restrictions of high-quality irrigation water from underground aquifers is affecting vegetable production in Southwest Texas. There is a need to develop efficient deficit-irrigation strategies to minimize irrigation inputs and maintain crop profitability. Our objective was to determine how growth, yield, and quality of cantaloupe (Cucumis melo L. cv. `Caravelle') are affected by irrigation systems with varying input levels, including drip depth position and polyethylene mulch. Stand establishment systems used were containerized transplants and direct seeding. Field experiments were conducted on a Uvalde silty clay loam soil. Marketable yields increased in the order of pre-irrigation followed by: dry-land conditions, furrow/no-mulch, furrow/mulch, drip-surface (0 cm depth)/mulch, drip-subsurface (10-cm depth)/mulch, and drip-subsurface (30 cm depth)/mulch. Pooled across all drip depth treatments, plants on drip had higher water use efficiency than plants on furrow/no-mulch or furrow/mulch systems. Transplants with drip-surface produced 75% higher total and fruit size No. 9 yields than drip-subsurface (10- or 30-cm depth) during the first harvest, but total yields were unaffected by drip tape position. About similar trends were measured in a subsequent study except for a significant irrigation system (stand establishment interaction for yield. Total yields were highest for transplants on drip-subsurface (10-cm depth) and direct seeded plants on drip-subsurface (10 and 30 cm depth) with mulch.

In agricultural production, nitrogen loss leads to economic loss and is a high environmental risk affecting plant growth, yield, and quality. Use of the N fertilizer with a urease inhibitor is thus necessary to minimize N losses and increase the efficiency of N. This study aimed to evaluate the effects of N-(n-butyl) Thiophosphoric Triamide (NBPT) on the growth, yield, and quality of pineapple. The experiment involved two foliar fertilizer treatments: 1% (w/v) urea solution with NBPT (2.25 mL kg−1 urea) was treated as NLU (NBPT Liquid Urea), and the same concentration of urea without NBPT served as the control. Both were applied 12 times, starting 1 month after planting (MAP) and continuing once a month for 12 months. The application of urea with NBPT notably increased the above-ground dry biomass per plant (20% and 10% at 8 and 12 MAP, respectively), leaf area per plant (23% and 15% at 8 and 12 MAP, respectively), N accumulation per plant (10%), PFPN (Partial Factor Productivity) (13%), and average fruit weight (15%) compared to the treatment with urea alone (control). The analysis of quality parameters indicated that urea with NBPT improves TSS (Total Soluble Solids) (19%), ascorbic acid (10%), and sucrose (14%) but reduces the total organic acid content (21%) in pineapple. When using urea with a urease inhibitor (NBPT), there was a significant improvement in growth, yield, quality, and nitrogen use efficiency, with the additional benefit of reduced nitrogen losses, in combination with easy handling. Hence, urea with a urease inhibitor can be used as a viable alternative for increasing pineapple yield by boosting growth with better fruit quality.

Field trials for two seasons (2018/2019 and 2019/2020) were conducted to investigate the influence of the addition of three levels of potassium (K) (K1 = 60, K2 = 120, and K3 = 180 kg K2O ha−1) and/or sulfur (S) (S1 = 175, S2 = 350, and S3 = 525 kg CaSO4 ha−1) to the soil, as well as the sowing date (the 1st of September, D1; or the 1st of October, D2) on the potential improvement of physiology, growth, and yield, as well as the quality characteristics of sugar beet yield under soil salinity conditions. With three replicates specified for each treatment, each trial was planned according to a split-split plot in a randomized complete block design. The results revealed that early sowing (D1) led to significant improvements in all traits of plant physiology and growth, in addition to root, top, and biological yields and their quality, gross and pure sugar, and K- and S-use efficiencies based on root yield (R-KUE and R-SUE). The K3 level (180 kg K2O ha−1) positively affected the traits of plant physiology, growth, yield and quality, and R-SUE, and reduced the attributes of impurities, impurity index, and R-KUE. Additionally, the S3 level (525 kg CaSO4 ha−1) affirmatively affected plant physiology, growth, yield and quality traits, and R-KUE, and decreased impurity traits, impurity index, and R-SUE. The interaction of D1 × K3 × S3 maximized the yield of roots (104–105 ton ha−1) and pure sugar (21–22 ton ha−1). Path coefficient analysis showed that root yield and pure sugar content had positive direct effects with 0.62 and 0.65, and 0.38 and 0.38 in both studied seasons, respectively, on pure sugar yield. Significant (p ≤ 0.01) positive correlations were found between pure sugar yield and root yield (r = 0.966 ** and 0.958 **). The study results recommend the use of the integrative D1 × K3 × S3 treatment for sugar beet to obtain maximum yields and qualities under salt stress (e.g., 8.96 dS m−1) in dry environments.
