CERES-Rice model was used to simulate growth and yield of four common rice varieties in Thailand with the attention on rate and timing of N application, a factor that most limits crop yield. The model predicted slightly higher grain yield than that observed for all varieties at N input of 75 kg/ha, but the differences between observed and simulated yields were not significant, except for varieties HSP and SPR90. The simulated grain[ratio ]straw ratio was significantly higher than the observed value for all varieties except that of HSP. There was no significant difference between the simulated and observed values of days to flowering. Generally, the model reasonably predicted the phenology and yields of RD23 and KDML105 varieties. The model was also used to compare the yields of KDML105 variety as influenced by rate and timing of N application grown in acid sulphate soils. There was a variation in predicted biomass yield with applied N rates at 0 and 150 kg/ha, but timing of application had no effect. In Aeric Endoquept and Sulfic Tropaquept soils at Suphan Buri and Pathum Thani rice research stations, the yield patterns remained unchanged and showed a positive response to N rate up to 75 kg/ha. The model estimated higher grain yields beyond 75 kg N/ha while the observed yield decreased. Based on the simulated yields for a 10-year period at the Asian Institute of Technology (AIT), Pathum Thani, Suphan Buri, Nakhon Pathom and Ratcha Buri rice research stations the varieties were ranked as: SPR90 > RD23 = HSP > KDML105. The model suggested that SPR90 is the most suitable variety for the central plain and its potential yield ranges from 4030 to 5600 kg/ha. Pathum Thani province, with acid sulphate soils, had the lowest potential for rice production.

Rice is the main product in Indonesia in the context of the supply of rice as a national food. Efforts to increase rice production are faced with various constraints such as fertilization ineffective and under-utilization of hybrid varieties by farmers. This study aims to determine the effect of differences in nutrient application through the leaves on the growth and yield of china’s hybrid rice. The method used is strip plots design. The design consists of two factors, namely the variety and diversity of nutrient factors. There are five varieties of rice that are used with 3 treatments a difference nutrient which is water, micro nutrient, complete nutrient. The results obtained indicate that the applications of micro-complete nutrient through the leaves have outcomes on the growth parameters that affect on plant height and the parameters of production that is the total number of grains per hill, weight of grain content per hill and percentage of grain content. Then, hybrid rice which has the highest potential yield after applying nutrient based on the amount of grain per clump is Hybrid I and Hybrid III.

The development of maize in shade areas is one of the efforts to increase the national maize production.The study objective was to determine the growth and yield adaptation of hybrid maize in shaded areas. The study was conducted in the sengon forest area of Kalices Village, Patehan District, Kendal Regency from March to September 2020. The study was designed using a randomized block design with split-split plots with treatments including: a) shade density (0%, 20% and 40%) as the main plot; b) cultivation technology (PTT and existing farmers) as sub-plots; and c) varieties (JH 37, Nasa 29 and Bisi 18) as sub-plots. Each treatment was replicated 3 times in order to obtain 18 treatment combinations and each replication was planted in a plot with a size of 350 m2. The parameters observed included the percentage of plants growing, plant height at harvest, age 50% male flowers, age 50% female flowers, cob height, cob length, cob weight, cob diameter, number of rows per cob, number of seeds per row, weight of dry seeds, seed moisture content, yield per plot and yield per hectare. The data were processed by analysis of variance and if there is a significant difference, it was further tested with DMRT at the 5% level. The results showed that the shading had a very significant effect on most of the yield components, namely cob length, number of seed rows per cob, wet and dry shell weight per 10 cobs, wet stubble weight per 10 plants, wet stubble weight, and dry shell weight. However, there is no significant effect on the growth components of growth power, cob circumference and cob position. The growth and yield adaptation of maize was better at 20% shade density compared to 40% shade density. On land with a shade density of 20%, the highest productivity was obtained in the Bisi 18 of 5.9 t/ha with a potential yield of 62.7%, followed by Nasa 29 of 5.8 t/ha with a potential yield of 58.41%, and JH 37 as much as 5.2 t/ha with a potential yield of 25%.

Marginal land along the coast should be utilized to increase the national rice production. In addition, the use of saline resistant varieties, it is necessary to determine the best seedling age for saline soil. This study aimed to evaluate the growth and yield responses of two rice varieties transplanted at different seedling age on saline soil. The experiment was arranged in a factorial Randomized Completely Block Design (RCBD) with three replications, conducted at saline coastal area of Baros, Yogyakarta, starting from January to June 2017. The first factor was rice varieties, consisting of Dendang and IR-64. Meanwhile, the second factor was the seedling age, consisting of 2 and 4 weeks after sowing (WAS) seedlings. The results showed that the growth and yield of two rice varieties (Dendang and IR-64) showed significant difference, and Dendang showed a better performance than IR-64. The higher yield of Dendang compared to IR-64 was supported by higher plant growth (shoot dry weight) and yield components (number of seeds per panicle, seed weight per plot, and productivity). The 2 and 4 WAS seedlings did not give significantly different effects on nearly all growth variables. However, 2 WAS Dendang rice seedlings had higher shoot dry weight. Meanwhile, IR-64 had higher leaf greenness in 4 WAS seedlings compared to that in 2 WAS seedlings.

Irrigation with saline water adversely affects rice production and degrades land productivity in the coastal zones of many countries in the world. This study aimed at developing a suitable irrigation management practice to reduce the harmful effects of salinity on rice production under saline water irrigation. An experiment in raise-bed lysimeters was set in a split-split-plot design with irrigation–drainage practice as the main factor, irrigation water salinity as the sub-factor and rice variety as sub-sub factor; main factor and sub-factor comprised four treatments and the sub-sub factor comprised three treatments, each with three replications. The treatments of the main factor were – T1: 2-5 cm continuous ponding, T2: continuous saturation, T3: changing irrigation water after 3 days of application by maintaining 2-5 cm ponding depth, and T4: changing irrigation water after 5 days of application by maintaining 2-5 cm ponding depth. The sub-factor comprised – SL1: fresh water as control, SL2: saline water of 6 dS m-1, SL3: saline water of 9 dS m-1, and SL4: saline water of 12 dS m-1. The sub-sub factor comprised three salt-tolerant rice varieties V1: Binadhan-8, V2: Binadhan-10, and V3: BRRI dhan-47. The irrigation–drainage practices T2 and T3 provided significantly (p£0.05) improved growth and yield attributes of the rice varieties under salinity water level SL3 and SL4 compared to T1 and T4 treatments. The treatment T3 maintained least exposure of the crop to high degree of salinity and produced satisfactory plant attributes by inhibiting the detrimental effects of salinity. Therefore, T3 is suggested for adoption in practical fields when provision for removing high saline water from the rice fields can be arranged.

Maize Response

Maize response to high nitrogenous fertilization levels is a means among other means to know maximum productivity, from this perspective, a field nitrogen management trial using five N levels (0, 23, 46, 69 and 92 kg N/ha) with three replications. The study was conducted in 2015 in Decha District, ModyoGomberaKebele of Kaffa Zone, SNNPR State. The experiment was laid out in RCBD. The result of this study indicated that effects of different rates of N fertilizer had influenced the growth and yield components of maize. The tallest plant (360.66 cm) was recorded from the application of 92 kg N ha-1 and the shortest (347.33 cm) from no N application. The ANoVA for the number of kernels per ear showed that the lowest kernels per ear (497.86) were obtained from no N application and the highest kernels per ear (588) were obtained from the application of 92 kg N ha-1 although there was no significant difference between the application of 69 and 92 kg N ha-1. Regarding to ear length the data showed that the longest ear (23.63 cm) was obtained from the application of 92 kg N ha-1. The effect of N on  grain yield indicated that there is no significant difference between the application of 69 and 92 kg N ha-1 even if there is a slight difference on yield. Generally, maximum N fertilization level (92 Kg N/ha) in this study area showed increase in growth and yield components (number of kernels per ear and ear length). However the application of 69 kg N ha-1 seems adequate to get the optimum yield.

Abstract Experiments were conducted at the teaching and research farm of Faculty of Agriculture, University of Ilorin, Nigeria to determine the effect of aqueous extract of Peperomia pelliucida and Terminalia catappa on the management of cyst nematode, Heterodera sacchari on some selected rice varieties. A screenhouse preliminary study was first carried out in December, 2014 to assess the pathogenicity of H. sacchari on ten varieties of rice from which five varieties were selected for field trials. The five selected rice varieties were grown on soil inoculated with cysts of H. sacchari. The field experiment was a 5×3 factorial type fitted into a randomized complete block design (RCBD). Soil nematode population, physiochemical soil analysis and phytochemical screening of the tests plants were carried out. Treatment application of aqueous leaf extract were conducted at the 2nd and 7th weeks after transplanting. Data were collected on the plant height, shoot, root weights, yield and soil nematode population. All numerical data were subjected to analysis of variance (Anova) using GENSTAT statistical package 12th edition and where significant differences were observed, means were separated using fisher’s protected LSD. Results from the study revealed that treatment combination of P. pellucida and T. catappa singly with FARO 60, FARO 61, and NERICA 8 performed significantly higher (p>0.05) than the other rice varieties for most of the growth and yield parameter measured. Significant differences occurred between shoot, root, and yield weight of treated plants and their control counterparts. There was no significant difference between the two plant extracts used with respect to parameters measured. Treated plants performed significantly higher than the control. Based on the results of the study, paddy farmers experiencing H. sacchari infestation are encouraged to treat the field with P. pellucida and or T. catappa, especially when planting FARO 60, FARO 61, and NERICA 8 as these combinations promise to give higher yield.

Swampland plays a critical function in agriculture, specifically in growing rice production. The study aimed to determine the effects of cropping systems and varieties on the rice growth and yield in acid sulfate soil of tidal swampland. The experiment was conducted in a potential acid sulphate soils in Kapuas Regency, Central Kalimantan Province. The experiment was arranged in a split plot design with three replications. The main plot consisted of three HYV’s of rice, namely Inpara 8, Inpari 32, and Margasari. The subplot consisted of five cropping systems, namely, Jarwo 2:1A, Jarwo 2:1B, Jarwo 2:1C, Hazton, and Tegel.  The plot size was 4 m x 5 m. The variables observed included initial soil properties, plant growth, and yield components. The jajar legowo cropping system in this study was not able to increase rice yields in acid sulphate soil.  There was an interaction effect of cropping systems and varieties on the plant height and number of tillers at vegetative phase. At generative and pre-harvest phases, there was significant single effect of variety and cropping system in the planting height and number of tillers, respectively. Both cropping system and variety significantly affected the number of panicles per hill, while panicle length, grain per panicle and grain yield were only affected by variety.  There was no significant effect of both factors on the number of filled grains per panicle.  Inpara 8 variety achieved the highest grain yield, which was 6.78 ton.ha-1 or equivalent to 4.34 ton.ha-1 of 14 % water content.

Beneficial Elements

Background: The beneficial elements availability such as silicon was determined rice growth and yield. Rice requires a different dose of silicon during the growing period. Experiment was aimed to investigate the effect of silicate levels, rice varieties and the interaction of the two on the growth and yields of two local Indonesian varieties of rice. Methods: A completely randomized design of factorial pattern with 4 replications was used in the experiment. Treatments consisted of No added SiO2 (Si-0); added 100 and 200 kg SiO2 ha-1, respectively for Si-100 and Si-200 and two local rice varieties, Pandan wangi (P1) and Mentik susu (P2). Result: The treatment had no significant effect on growth and yield of rice. Addition of 100 and 200 kg SiO2 ha-1 to P1 and P2 did not show a significant difference on the growth and yield of rice compared to control (P0). Plant height and root dry weight at P1 was lower than P2, but the 1,000-grain weight was showed, vice versa. Silicon addition up to 200 kg SiO2 ha-1 may not be recommended to be applied in rice cultivation, especially Pandan wangi and Mentik susu varieties. Improving the two varieties, further research is needed by increasing the silicon doses.
