“…The number of panicles affects grain production (Anggraini et al, 2013) with different densities. The number of productive panicles results in total plant productivity (Mohanan & Mini, 2007), panicle length 22.70 -30.50 cm at harvest with an average of 26.28 cm. Research results of Prabawa & Purba (2019) obtained an average of 23.52 to 25.09 cm.…”

One effort to increase food security is to increase rice production by providing adequate nutrition to rice plants with organic fertilizers and growth regulators (PGR). The aim of this study was to measure the growth and production of black rice (black oryza), as well as the distribution of the average plus or minus data through the treatment of various concentrations of PGR and doses of organic fertilizer. The research design was a two-factor factorial randomized block design. The first factor of PGR concentration (Z) consisting of 5, namely 0 (Z0), 1 (Z1), 1.5 (Z2), 2 (Z3) and 2.5 (Z4) ml/L of water. The second factor of organic fertilizer (P) consisting of 5, namely 0 (P0), 1 (P1), 2 (P2), 3 (P3) and 4 (P4) tons/ha. The treatment was repeated 5 times so that 125 experimental units were provided. The best grain yield 47.03 g/panicle was resulted from a single effect of PGR treatment at a concentration of 2 ml/L, whereas single treatment using organic fertilizer at a dose of 4 ton/ha produced grain of 46.23 g/panicle. The best combination of PGR concentration of 2 ml/L of water with organic fertilizer 4 tons/ha, resulted the highest grain yield of 50.24 g/panicle, equivalent to average dry harvested grain of 5.02 ton/ha or 3.26 ton/ha of dry unhusked grain. The distribution of the average plus minus data is good with a low average distribution for all measurement components.

“…We investigated the differences in the growth, photosynthetic activity, production and utilization of photosynthates, and cell wall development between ten rice species, two cultivated and eight wild germplasms. The tillering is species-specific as a botanical characteristic [ 31 ], and thus is considered a consequence of genetic variation during acclimating to habitat environments. The difference in tillers was not observed in our study, however, wild rice species which are generally perennial, show an extended tillering duration compared to the cultivated species ( Figure 1 and [ 32 ]), and this is likely to result in different uses of photosynthates.…”

The ever-increasing human population alongside environmental deterioration has presented a pressing demand for increased food production per unit area. As a consequence, considerable research effort is currently being expended in assessing approaches to enhance crop yields. One such approach is to harness the allelic variation lost in domestication. This is of particular importance since crop wild relatives often exhibit better tolerance to abiotic stresses. Here, we wanted to address the question as to why wild rice species have decreased grain production despite being characterized by enhanced rates of photosynthesis. In order to do so, we selected ten rice species on the basis of the presence of genome information, life span, the prominence of distribution, and habitat type and evaluated the expression of genes in photosynthesis, photorespiration, sucrose and starch synthesis, sucrose transport, and primary and secondary cell walls. We additionally measured the levels of a range of primary metabolites via gas chromatography–mass spectrometry. The results revealed that the wild rice species exhibited not only higher photosynthesis but also superior CO2 recovery by photorespiration; showed greater production of photosynthates such as soluble sugars and starch and quick transportation to the sink organs with a possibility of transporting forms such as RFOs, revealing the preferential consumption of soluble sugars to develop both primary and secondary cell walls; and, finally, displayed high glutamine/glutamic acid ratios, indicating that they likely exhibited high N-use efficiency. The findings from the current study thus identify directions for future rice improvement through breeding.

This research was aimed to know the effects of the furrow system containing organic matter for rainfed, to growth and yield of several varieties on agroforestry system with Kayu Putih. The research was conducted in Petak 83 Resort Pengelolaan Hutan (RPH) Menggoran, Bagian Daerah Hutan (BDH) Playen, Kesatuan Pengelolaan Hutan (KPH) Yogyakarta from March to August of 2018. The experimental design applied the strip plot design. The vertical factor was the furrow system of treatment consisting of 2 levels i.e, without furrow + without organic matter and furrow + organic matters. The horizontal factors were the varieties of upland rice consisting of 3 varieties i.e. Situ Patenggang, Situ Bagendit, and Ciherang. Then the collected data were analyzed by analysis of variance (Anova) applying a level of significance α = 5%. Whenever the significant differences among treatments were found, further analysis was carried out by applying the Tukey's HSD (Honestly Significant Difference) at 5% levels. The result showed that furrow containing organic matter was able to support plant growth in dry land. Situ Patenggang has highest adaptation to growth dan produce in drought stress. The combination of furrow containing organic matter with Situ Patenggang showed the best result in CGR, total root length, total chlorophyll content, number of panicle, number of spikelet per panicle, 1000 grain weight and estimated productivity.
