Sugarcane (Saccharum spp.) is an important tropical crop around the world, involving in Indonesia, however low productivity is still problem for it. The study was aimed to investigate effect of different planting methods on improving cane growth-yield performances and their partial economic analysis. The study was conducted at Gedangdowo, Jepon, Blora District, Central Java, Indonesia from 2015-2017 at initial planting (IP) to sugarcane ratoon SR-1 and SR-2. Material used was qualified seeds of PS.862 variety. Three planting methods were tested: 1) double trench system (DTS) with 50 cm distance between trench and 135 cm distance between double trenches; 2) single trench system (STS) with 120 cm distance of canter to center (CTC) and 3) STS with 110 cm distance of CTC. The experiment was arranged in randomized complete block design (RCBD) with 6 replications. Results of the study revealed that DTS 50/135 was the most appropriate planting method inducing higher cane productivity up to 129.12 t/ha in IP, then increased up to 134.1 t/ha in SR-1 and declined down to 114.1 t/ha in SR-2. Percentage of cane productivity in DTS 50/135 increased up to 40.8% in IP, 51.1% in SR-1 and 64.6% in SR-2. Higher R/C ratio up to 1.99 and 1.94 was performed by STS 120 followed by DTS 50/135. Increasing R/C ratio noted in STS 120 and DTS 50/135 was 18.3 and 21.3%, respectively on SR-1 compared to STS 110. The planting method can be applied to improve sugarcane productivity and its R/C ratio for other varieties.

<p>One of the problems encountered in the development of sugarcane (Sacharrum officinarum L.) includes the availability of sugarcane seed both in quality and quantity. Evaluation of bud sett planting method in seed production was required in order to achieve the expected results. The study was conducted at the experiment station Muktiharjo, Central Java in 2012 using PSJT 941 varieties. Treatments applied were the different number of buds on bud sett which were at 3 levels, 1 bud, 2 buds or 3 buds. Research was arranged in a randomized complete block design (RCBD) with 5 replications. Observations were conducted on germination, tillering, plant height, number of stems, number of suckers and number of buds. The data obtained were analyzed with ANOVA and further tested using the Duncan test. Production assessment modeling approach was performed by a regression analysis. Calculation of stem number on 2 buds showed the highest with 9.6 stems/m, 9.2 buds/stem and with the sucker numbers lowest at 0.38 suckers/m. The highest production buds was obtained at planting 2 buds with 847,848.06 buds/ha which can be used as 8.83 ha for the milled sugarcane plantation. Assessment of bud production per hectare could use equation Y = 159655,48.e0,171.X with the independent variable of stem numbers per meter with a correlation coefficient of 0,9007 and a standard error of 1,0699.</p>

Background: Cassava (Manihot esculenta Crantz) is a source of carbohydrate among the population after maize and rice and highly contributes to food security and livelihood to majority of small scale farmers in Sri Lanka as well as in African continent. The production of these starchy plants is declining due to the problem of low yield, high labor cost, pest and diseases damage and shortage of land. However among the yield limiting factors of cassava, the planting method of stem cuttings which depend on plant cultivar and environmental conditions. Therefore, the present study was carried out to reveal information on the effect of planting methods on the growth and yield attributes of cassava. Methods: The field experiment was conducted at the Farmer’s field in the Batticaloa and laboratory experiment was led in South Eastern University of Sri Lanka which is located in Sri Lanka. The field trail was carried out over a period of four months during from May to September in 2018. The treatments used were three planting positions (Angled, vertical and horizontal) and two cultivars (“cv. Local” and “cv Kirikawadi”) were combined in factorial arrangement and laid out in randomized complete block design with three replications. Result: The result revealed that root yield was significantly (P d” 0.05) affected by the interaction effects of the planting position and varieties. Significant differences were observed among planting methods in all tested variables. Based on the study, storage roots yield of cassava could be enhanced by planting method of angled position.

The purpose of this work was to test yacon planting practices in low elevation conditions. The experimental design was a randomized block design (RBD) with subdivided plots and four replications. Treatments comprised of three planting methods: furrow; ridges and pits; each treatment was divided into subplots, which were four planting depths: 5, 10, 15, and 20 cm. The following variables were tested: sprouting speed, vigorous sprouting rate, average time for sprouting, rhizophore mortality rate, soil temperature and moisture, shoot dry weight, and yield of rhizophores, tuberous roots, total yield, and marketable tuberous roots. The planting methods using pits and furrows had lower seedling mortality rates (30,2 and 41,4% compared to ridges), while furrow led to a higher total tuber yield (17,5 and 18,9% higher than ridges and pits), using depths of 5 and 10 cm. The system with pits also achieved significant yields at 10 cm depth. Using ridges as the planting method would be possible, at depths of 10 and 15 cm, but yields would be lowered. For the conditions of this study, the highest yield of marketable roots was obtained using furrow at 5 and 10 cm of panting depth

Crop management is necessary in sprouting, cycle and productivity of most plants of commercial interest. However, recommendations and information are scarce for yacon cultivation, mainly regarding the possible interferences of planting method and depth in the crop development and production. Therefore, the objective was to study the influence of the planting methods and depths on yacon tuberous roots development and production in high altitude conditions. The experiment was a randomized complete block design, with four replications, in a subdivided plots scheme. The plots consisted of three planting methods (groove, pit and ridge) and subplots characterized by four planting depths (5, 10, 15, and 20 cm). Evaluations were carried out from the sprouting process of the rhizophores to the yield of tuberous roots. The planting methods in a pit and ridge had lower seedling mortality rates (27.5 and 20.2% lowers than grooves) and higher yields of tuberous roots (31.2 and 21.4% higher than grooves). The planting depths of 5 and 10 cm of the rhizophores were shown to be the most suitable for yacon cultivation for the three planting methods.

This study aimed to observe the growth and yield of Chiherang rice (Oryza sativa L) and weeds in response of different planting methods and weeding frequencies. We conducted the study in Semampir, Argorejo, Sedayu Sub-district, Bantul District on April until August, 2018. We arranged field study using randomized complete block design in 3x2 factorials with 3 times repetition. First factor was Jajar legowo (J) stratified as 3 levels; 2:1 (J1), 4:1 (J2), dan 6:1 (J3). Second factor was weeding frequency in 2 levels which were 2 times in 14 and 70 hst (P1) and 3 times in 14, 49 and 70 hst (P2). Observed variables include Ciherang rice growth (plant height, total tillers, percentage of productive tillers, fresh and dried weight of each plant), components of rice yield (grain dry weight of each harvest, percentage of filled grains, yield of each hectares), and weeds (type of weeds, fresh and dry weight of weeds). We analyzed results using variance analysis with significant level of 5%, followed with 5% DMRT test. We found that application of jajar legowo planting method and weeding frequency do not correlates with all growth and weeding frequency variables of Ciherang rice and weeds. 2:1, 4:1 and 6:1 jajar legowo planting methods do not show significant impact both on Ciherang rice growth and yield, and also weeds. Both 2 times (14 and 70 hst) and 3 times (14, 49 and 70 hst) also do not have significant impact on all variables observed.Keywords: Jajar Legowo, Weeding Frequency, Ciherang Rice

Field experiments were carried between May and July 2014 to investigate the effects of three land preparation methods (flat surface, raised beds and ridges) on growth, yield and proximate composition of groundnut. The plots layout followed complete randomized block design with three replications. The results showed that growth parameters such as plant height, number of primary branches and leaf area were the highest in raised beds, followed by ridges and flat surface. Yield components such as number of matured pods per plant, number of seeds per plant and seed weight per plant were significantly higher in raised beds compared to other planting methods. Higher pod and seed yield were recorded under raised beds, but these were not statistically different from those of ridges. Regardless of the planting method, the percentage moisture, ash, fibre crude protein, crude fat and carbohydrate had values that ranged between 11.30 ± 0.88-10.67 ± 0.61%, 2.38 ± 0.33-2.07 ± 0.20%, 4.97 ± 0.05-9.95 ± 0.19%, 23.84 ± 0.14-26.51 ± 0.20%, 44.17 ± 0.37-48.86 ± 0.47% and 5.89 ± 0.14-9.59 ± 0.19% respectively. However, raised beds planting method had a remarkable influence on ash, fiber and crude protein, but limit the fat and carbohydrates contents of the seeds when compared to other planting methods. In view of its influence on growth, yield and some aspects of proximate composition, raised beds method of planting is therefore suitable for producing Arachis hypogaea L., ‘MK 373’ cultivar of groundnut.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to December 2014 to evaluate the effect of planting method and weeding regime on the performance of transplant Aman rice. Two planting methods viz. line transplanting and haphazard transplanting and six weed control treatments viz. no weeding, one hand weeding at 21 DAT, two hand weeding at 21 and 42 DAT, pre-emergence herbicide Rifit 500 EC at 7 DAT, pre-emergence herbicide Rifit 500 EC at 7 DAT + one hand weeding at 42 DAT and weed free were used as experimental treatments with three replications in a randomized complete block design (RCBD). Planting methods, weeding treatment and their interaction significantly influenced most of the crop characters and yield components of transplant Aman rice. The highest effective tillers hill-1 (9.30),grain panicle-1 (185.4), grain yield (3.89 t ha-1), straw yield (5.57 t ha-1), biological yield (9.54t ha-1) and harvest index (41.08) were obtained from line transplanting. Complete weed free treatment produced the highest total tillers hill-1 (12.37), effective tillers hill -1 (9.89), grain yield (4.11 tha-1) and biological yield (9.94 t ha-1).The highest total tillers hill-1(13.07), effective tillers hill -1(10.70), grain yield (4.50t ha-1) and biological yield (10.79 t ha-1) were obtained from line transplanting under weed free treatment. Results revealed that line transplanting with pre-emergence herbicide Rifit 500 EC at 7 DAT + one hand weeding at 42 DAT might be used to control weeds effectively and to get higher yield of transplant Aman rice.Progressive Agriculture 27 (3): 249-255, 2016

To produce large elephant garlic (Allium ampeloprasum L.) bulbs in the southeastern United States, stock cloves must be planted in the fall. During extremely cold winters, however, winter survival rates can be very low. A 2-year study was undertaken to examine practices to increase winter survival rates. Two clove sizes (≤20 g or >20 g), three nitrogen rates (112, 224, and 336 kg/ha), and three planting methods (flat, mulched, and hilled) were tested in a RCB design with four replications. For all planting methods, cloves were set in a shallow trench and covered with soil to ground level. This was also the flat treatment. For the mulched treatment, 7 cm of straw was spread on top. For the hilled treatment, soil was mounded 10 to 15 cm high over the ground level. Cloves were planted in early October and harvested in mid-June. Use of large planting stock cloves increased winter survival rates during the harsh winter, but had no effect during the mild winter. Both years, winter survival was reduced with the flat treatment. Yields of marketable bulbs were 4 to 5 times higher when >20 g cloves were planted than when ≤20 g cloves were used. Nitrogen rate and planting method had no effect on yields. The >20 g cloves also produced larger bulbs than the smaller cloves. Of the three planting methods, the flat treatment produced the smallest bulbs. Bulbs were much larger following the mild winter than the harsh winter.

Positive Effect

Achieving high yields is a challenge for sugarcane producers due to the diverse environmental conditions to which the crop is subjected. In tropical and subtropical regions, where sugarcane is typically cultivated, crop diseases are common. This necessitates the development of disease management techniques. Among these techniques, chemical control is of particular significance due to the development of new antifungal agents, such as pyraclostrobin. For some crops, pyraclostrobin has a positive influence on yield due to its effects on plant physiology. The aim of this study was to evaluate the physiological responses and yield of three sugarcane cultivars treated with the fungicide, pyraclostrobin. The experiment was performed in a randomized block design (RBD) with a split-plot arrangement; the variables analyzed were the application or non-application of fungicide in the plots and, in the subplots, the evaluation times after fungicide application. Both the rate of photosynthesis and the antioxidant enzyme (Superoxide Dismutase, Catalase and Ascorbate Peroxidades) activity increased in plants treated with fungicide in comparison to untreated plants, and in the RB855156 cultivar the stomatal conductance, transpiration, and nocturnal respiratory rate were increased. Furthermore, application of pyraclostrobin increased stalk yield and the green biomass index in the RB855156 and RB86751 sugarcane cultivars. In certain cultivars of sugarcane, application of pyraclostrobin leads to an increased yield.
