At Kimberley Research Station in the 1962 dry season, two varieties of Brassica ca.mpe.rtris and one of B. juncea were sown under irrigation at four dates from May 1 to July 2 with six nitrogen fertilizer treatments. Seed yield was reduced with later date of sowing. There was a small linear response to nitrogen fertilizer up to 80 lb an acre nitrogen. Applying half the nitrogen at sowing and half at budding showed no advantage over applying all the nitrogen at sowing. Oil content was also reduced with later date of sowing. Nitrogen fertilizer at the highest level reduced oil content slightly. Although seed and oil yield were highest at the first sowing, dry matter and nitrogen yield of tops were highest at the second sowing. The fall in seed and oil yield with later date of sowing appeared to be associated more with rising temperature during the seed maturation period than with general vegetative performance.

<p><span>A field experiment was conducted to evaluate yield and some qualitative characteristics of four cultivars of sweet basil treated with different levels of nitrogen fertilizer. The experiments were located on the Agricultural Research Station of Khorramabad, Iran, during the 2016-2017 growing season. Treatments were arranged in factorial split-plot-in time in randomized complete block design with three replications. Experimental treatments were four cultivars of sweet basil (<em>Ocimum basilicum</em> ‘Italian Large Leaf’, <em>O. basilicum</em> ‘Mobarakeh’, <em>O. basilicum</em> ‘Cinnamon’ and <em>O. basilicum </em>‘Thai’), three levels of nitrogen fertilizer (0, 100 and 200 kg ha<sup>-1</sup> urea) and three harvests. The highest total dry mass (3482.4 kg ha<sup>-1</sup>) was related to ‘Italian Large Leaf’ with the application of 200 kg ha<sup>-1</sup> urea at the second harvest. The maximum (26.79 kg ha<sup>-1</sup>) essential oil yield belonged to 100 kg ha<sup>-1 </sup>urea. The highest concentrations of main constituents of essential oil, except methyl chavicol, 1,8-cineole and methyl cinnamate were obtained by control (without nitrogen fertilizer). Italian Large Leaf cultivar and application of 100 kg ha<sup>-1</sup> urea are recommended to access an acceptable agricultural yield and essential oil yield in sweet basil under the environmental condition similar to Khorramabad</span></p>

The sowing date is an important factor for expanding the cultivated area of rapeseed and affects seed yield, oil content, and fatty acid compounds. Micronutrient elements play an important role in improving the vegetative and reproductive growth of the plant, especially under conditions of biological and environmental stresses. A two-year experiment (2014-2016) was performed to study the response of rapeseed genotypes to foliar application of micronutrients on different sowing dates. The treatments were arranged as a factorial-split plot in a randomized complete block design with three replicates. Three sowing dates of 7 (well-timed sowing date), 17, and 27 (delayed sowing dates) October and two levels of foliar application with pure water (control), selenium (1.5%), zinc (1.5%), and selenium+zinc (1.5%) were factorial in the main plots and five genotypes of SW102, Ahmadi, GKH2624, GK-Gabriella, and Okapi were randomized in the subplots (a total of 30 treatments). Seed yield, oil yield and content, oleic acid, and linoleic acid were reduced when rapeseeds were cultivated on 17 and 27 October, while the contents in palmitic, linolenic, and erucic acids, and glucosinolate increased (p < 0.01). a selenium+zinc treatment improved seed yield, oil content and yield (p < 0.01). The oil quality increased due to increased contents of oleic and linoleic acids under the selenium+zinc treatment (p < 0.01). The GK-Gabriella and GKH2624 genotypes are recommended to be sown on well-timed (7 October) and delayed sowing dates (17 and 27 October) and treated with selenium+zinc due to the higher oil yield, linoleic and oleic acids.

A field experiment was conducted at research station of College of Agriculture University of Baghdad in Abu-Griab. The aim was to study early generation of cowpea under water stress regime. The purpose was to diagnose which genotypes have high yield and stability under water deficit. The experiment consisted of two levels of water deficit (50 and 75%) and three genotypes selected and original genotype. Randomized complete block design (RCBD) within split plots arrangement with three replicates in two seasons of 2014 were used. The results revealed that S5 gave highest mean in chlorophyll index and dry matter per induvial plant were 74.66 , 68.44 SPAD. in spring and autumn season respectively. In addition to , S5 had a short period to reproductive phase. S5 gave highest mean seed yield per hectare and water use efficiency were 1246.23 and 2211.84 Kg.ha-1 , 0.19 and 0.51 in spring and autuman seasons, respectively. S4 gave less days to 50% flower were 56.17 and 40.33 in spring and autumn season, respectively. PCV and GCV were so dose in peroxide (13.0 ,12.13%) and (5.70 , 4.68%) in spring and autumn seasons, respectively. Stability values were high in peroxidase , proline , water use efficiency and seed yield (87, 94.3%),( 99.87 , 99.82%), (93.22, 92.33%), (86.5,93.46%) in spring and autumn , respectively. It can be concluded the significant dependance on certain triats in diagnosing the genotypes that tolerated to drought . Therefore S5 was tolerant of drought because of superiority in relative water content. . It is important to use S5 in genotypic and environmental interactions for many years and locations to determine its stability. It can be rationled much quentity of water by following irrigation at 75% . Water deficit which reduced number of irrigation to ten in autumn season, leading to increase of water use efficienly to 0.37 .

A field experiment was conducted at Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat during Rabi seasons of 2016-17 and 2017-18 to study the response of niger to different levels of nitrogen, phosphorus and potassium as well as sulphur on growth, yield and oil content of niger. The experiment was laid out in Factorial Randomized Block Design with three replications. The treatments comprised of three NPK levels viz., F1 (20-10-10 kg N-P2O5-K2O ha-1), F2 (25-12.5- 12.5 kg N-P2O5-K2O ha-1), F3 (30-15-15 kg N-P2O5-K2O ha-1) and three S levels viz., S1 (no sulphur), S2 (10 kg S ha-1), S3 (20 kg S ha-1). Application of F3 (30-15-15 kg N-P2O5-K2O ha-1) and S3 (20 kg S ha-1) recorded maximum and significantly higher seed yield (q ha-1), oil content (%), oil yield (q ha-1) as well as growth and yield attributing parameters viz., plant height, number of leaves plant-1, number of branches plant-1, number of capitulum plant-1 and number of seeds capitulum-1 during both the years. Test weight was not influenced significantly during both the years. Interaction effects of NPK (F) and sulphur (S) were found to be not significant in respect of growth and yield attributing characters in both the years. In case of seed yield (q ha-1) and oil yield (q ha-1) interaction effect were found to be significant in both the years.The highest gross return (Rs. 23,905.00 in 2016-17 and Rs. 22,400.00 in 2017-18) and net return (Rs. 11,184.86 in 2016-17 and Rs. 9679.86 in 2017-18) were recorded by F3S3 in both the years. In case of benefit-cost ratio, the higher value (1.88 and 1.76, respectively) was recorded with F3S3 during 2016-17 and 2017-18.

<p>Citronella grass nowadays are developed in the highland that dominated by Andosol soil type. Thus, it is important to find out the proper fertilizer dosage, especially potassium, for citronella grass cultivation in Andosol soil. This study aimed to obtain the optimal of potassium dosage for growth, production and quality of Citronella grass oil. It was conducted at Manoko research station in Lembang, Bandung West Java from July 2014 to August 2015. This research was arranged in randomized block design, with 5 treatments and 5 replication. The treatments consisted of 5 potassium dosages: 1) without potassium, 2) 30 kg/ha K<sub>2</sub>O, 2) 60 kg/ha K<sub>2</sub>O, 3) 90 kg/ha K<sub>2</sub>O, and 5) 120 kg/ha K<sub>2</sub>O. The application of potassium on Andosol enhanced plant growth, production and oil yield significantly.  However, it did not affect the quality of citronella grass oil (citronella and oil content) significantly. The application of 30 kg/ha K<sub>2</sub>O in citronella grass cultivation on Andosol has the best result. The oil yield was 1.20% (the 1<sup>st</sup> harvest), 1.28% (The 2<sup>nd</sup> harvest) and 1.23% (the 3<sup>rd</sup> harvest), with yield increment 6.9-7.5%. Oil content was 1,40-1,70%. The K nutrient uptake also improved around 11.76%. Citronella content from all treatments ranged from 36.97-37.68%. This result suggested that the low dosage of potassium in Andosol was sufficient to enhance primary metabolites process (indicated by growth and yield). However, it had no direct effect on the secondary metabolite process (represented by essential oil and citronella content). Based on the soil analysis after trial, the K residues in the soil was still high. However, its availability for the plants had to be tested further.</p><p><strong>Keywords: </strong><em>Cymbopogon nardus</em>, citronella content, oil content, oil yield, potassium.</p><p> </p><p><strong>Abstract</strong></p><p class="BodyText22">Pengembangan tanaman seraiwangi saat ini cenderung ke daerah-daerah dataran tinggi yang umumnya didominasi oleh tanah  Andosol, oleh sebab itu perlu diketahui kebutuhan pupuk terutama kalium untuk tanaman seraiwangi di daerah tersebut. Penelitian ini bertujuan untuk memperoleh dosis K yang optimal untuk pertumbuhan, produksi dan mutu minyak sitronela yang dihasilkan dari tanaman seraiwangi. Penelitian ini telah dilakukan di Kebun Percobaan Manoko Balittro Lembang, Jawa Barat, dimulai dari Juli 2014-Agustus 2015. Penelitian ini menggunakan rancangan acak kelompok dengan 5 perlakuan dan 5 ulangan. Perlakuan terdiri dari 5 dosis K yaitu: 1) tanpa kalium (K1), 2) dosis 30 kg/ha K<sub>2</sub>O, 3) dosis 60 kg/ha K<sub>2</sub>O, 4) dosis 90 kg/ha K<sub>2</sub>O, dan 5) dosis 120 kg/ha K<sub>2</sub>O. Hasil penelitian menunjukkan bahwa pemberian kalium pada tanah Andosol berpengaruh terhadap peningkatan pertumbuhan tanaman, produksi dan rendemen, namun tidak mempengaruhi mutu minyak seraiwangi yang dihasilkan (kadar sitronela dan kadar minyak). Pemberian K sebanyak 30 kg/ha merupakan dosis terbaik dalam budidaya seraiwangi pada tanah Andosol. Rendemen yang diperoleh 1,20% (panen ke-1), 1,28% (panen ke-2) dan 1,23% (panen ke-3) dengan peningkatan sekitar 6,9-7,5%. Kadar minyak yang dihasilkan 1,40-1,70%. Peningkatan serapan hara K yang diperoleh sebesar 11,76%, dengan kadar sitronela 37,68%. Dengan demikian pemberian K pada tanah Andosol sangat diperlukan dalam proses metabolit primer (pertumbuhan dan produksi) dalam jumlah yang tidak terlalu tinggi, namun tidak berpengaruh langsung terhadap proses pembentukan metabolit sekunder (kadar minyak dan kadar sitronela). Selain itu  kadar K yang tersisa di dalam tanah masih cukup tinggi, namun perlu dilakukan pengujian lebih lanjut mengenai ketersediaannya bagi tanaman.</p><p><strong>Kata kunci</strong>: <em>Cymbopogon nardus</em>, kalium, kadar minyak, rendemen minyak, sitronela</p><p class="BodyText22"><span lang="EN-US"><br /></span></p>

This study was carried out to determine the efficiency of nitrogen (N) doses (0, 30, 60, and 90 kg N ha−1) under supplemental potassium (K) application (50 kg K2O ha−1) on black cumin in 2011 and 2012. The results showed that increased N levels resulted in increasing seed yield and N and K contents in seed, while oil content decreased. The seed yield and oil yield were peaked at the doses of 60 kg N ha−1and 50 kg K ha−1. An increase in N doses caused a reduction in oil content regardless of K supply. Saturated fatty acids and oleic acid were slightly increased by K application, while minor changes in linoleic acid were detected. It was concluded that 60 kg N ha−1with supplemental K application should be advised for enhancement in seed yield, oil yield, and N and K contents in seeds of black cumin without significant changes in fatty acid composition.
