“…Use of integrated crop management practices is the best approach for addressing the abovementioned issues. During grain production, dry matter production and leaf area index are the main growth-limiting factors (Rajput, Rajput, & Jha, 2017). Some studies have suggested that increasing dry matter accumulation before flowering has an important effect on grain yield (Pal, Mahajan, Sardana, & Chauhan, 2017;Wu et al, 2013).…”

Integrated crop management practices can improve rice (Oryza sativa L.) grain yield, but the effects of such practices on dry matter accumulation and photosynthetic productivity are inconsistent and not well understood. The primary objective of this study was to investigate the effects of integrated crop management practices on dry matter accumulation and redistribution, photosynthetic production, and yield of rice in northeast China. Medium‐ and high‐yielding potential japonica rice cultivars were grown using four crop management practices, including no N application (N0), local farmers’ cultivation practice (FP), high‐yield cultivation practice (HYP), and super‐high‐yield cultivation practice (SHYP). The increases in average yield with the HYP and SHYP treatments were 16.87 and 36.70%, respectively, in 2017 and 14.70 and 31.05%, respectively, in 2018, compared with FP. Increases in effective panicle number and spikelet number per panicle were the main reason for the increase in yield under the integrated crop management treatments. Compared with FP, the HYP and SHYP treatments significantly increased the population dry matter by 26.40 and 56.64%, respectively, before the heading stage. Relative to N0 and FP, HYP and SHYP significantly increased the dry matter export, export rate, and translocation rate in the leaves, stems, and sheaths and significantly increased the photosynthetic potential throughout the growth stage and the net assimilation rate after the tillering stage. These increases were critical for improving the quality of rice and achieving higher yields. Our study provides a theoretical basis for the development of high‐yield cultivation methods for rice in northeast China.

“…It is clear that plant under elevated BL has high NAR. Rajput, Rajput, & Jha (2017) reported that increases in plant growth on different planting geometries and depths of SRI increased 30 % total biomass in rice and also increased 4 % NAR compared to control. The NAR reduction caused by ontogenetically development of fig shows the plant reaching maturity.…”

“…Net Assimilation Ratio was measured by Beadle formula (Rajput, Rajput, & Jha, 2017). This formula measures the rate of dry matter production per unit leaf area or the net gain in dry weight of the plant per unit leaf area per unit time.…”

There is limited information and insures for next studies on exogenous brassinolide application fig cultivar of Masui Dauphine (MD) and Improved Brown Turkey (IBT). Therefore, the research objective was to determine the impact of concentrations of exogenous brassinolide application on Leaf Area Index (LAI), Leaf Mass Ratio (LMR), Net Assimilation Rate (NAR), Relative Growth Rate (RGR), and Specific Leaf Area (SLA) of fig. Fig resources were propagated using stem cuttings and were transferred into 3:2:1 mixed soil (topsoil:organic matters:sand) media. Two cultivars of fig treated with brassinolide (control, 50, 100 and 200 ml/L) were repeated four times and constructed by Split Plot Randomized Complete Block Design. Changes in the parameter of LAI, LMR, NAR, RGR, and SLA were investigated monthly. There was a significant effect of fig variety alone on LAI, SLA and LMR but it wasn't affected on NAR and RGR. SLA and LMR were influenced by brassinolide but not on LAI, NAR and RGR. Cultivar IBT showed higher responses to these parameters than cultivar MD after receiving brassinolide treatment. The interaction between brassinolide and variety was significant on LAI, SLA and LMR of fig except in the parameters of NAR and RGR.

ABSTRAKKencur (Kaempferia galanga L.) merupakan salah satu tanaman obat potensial dengan permintaan yang cukup tinggi sehingga budi daya kencur masih cukup menjanjikan. Untuk memeroleh pertumbuhan dan produksi rimpang yang tinggi, ketersediaan aksesi kencur yang unggul merupakan faktor penting di dalam budi daya kencur. Pertumbuhan yang optimal dan produksi tinggi pada beberapa aksesi kencur akan diperoleh apabila dibudidayakan pada ketinggian tempat yang sesuai. Tujuan penelitian adalah mendapatkan aksesi kencur dengan pertumbuhan serta hasil yang baik pada lokasi dengan ketinggian tempat yang sesuai. Penelitian ini menggunakan metode rancangan petak terbagi, sebagai petak utama adalah ketinggian tempat dan aksesi kencur sebagai anak petak. Lokasi penanaman sebagai petak utama pada ketinggian 214 dan 780 mdpl. Aksesi kencur terdiri atas tujuh taraf, yaitu aksesi PBG (Purbalingga), CLP (Cilacap), PWJ (Purworejo), KRA (Karanganyar), PCT (Pacitan), MAD (Madiun), dan pembanding GAL 2 (Galesia 2). Hasil penelitian menunjukkan bahwa ketinggian tempat memengaruhi klorofil total daun, konduktansi stomata, laju transpirasi, laju fotosintesis, bobot kering rhizom, dan produksi. Jumlah daun dipengaruhi oleh ketinggian tempat dan aksesi kencur. Interaksi antara ketinggian tempat dan aksesi kencur memengaruhi luas daun dan kadar gula terlarut rimpang. Produksi rimpang kencur di daerah ketinggian 214 mdpl lebih tinggi daripada di daerah ketinggian 780 mdpl. Kencur dapat tumbuh baik dengan hasil yang baik pada daerah ketinggian 214 mdpl. Aksesi PBG (Purbalingga) dan PWJ (Purworejo) berpotensi untuk dikembangkan di lokasi dengan ketinggian 214 mdpl karena mempunyai produksi tinggi. ABSTRACT Galanga (Kaempferia galanga L.) is one of the potential medicinal plants with high demand. Therefore, galanga cultivation was still quite promising. To obtain the optimum growth and high rhizome production, the superior galanga accessions are required. The optimal growth and high production of galanga accessions will be obtained if cultivated at the area with appropriate altitude. The purpose of the study was to obtain galanga accession with a better growth and high yield at the area with a suitable altitude. This study used split-plot design; altitude as a main plot and accession as a subplot. The location as a main plot consisted of altitudes of 214 and 780 masl. This study used seven accessions i.e., accession of PBG (Purbalingga), CLP (Cilacap), PWJ (Purworejo), KRA (Karanganyar), PCT (Pacitan), MAD (Madiun), and GAL2 (Galesia 2) as control. The results showed that different altitudes significantly affected the total chlorophyll content, stomatal conductance, transpiration rate, photosynthesis rate, dry weight, and rhizome yield. The number of leaves was influenced by altitude and accession of galanga. The interaction between altitude and accession of galanga significantly affected the leaf area and the soluble sugar concentration in the galanga rhizome. The rhizome yield at low altitude was higher than in high altitude. PBG (Purbalingga...
