This study was initiated with the objective of determining the effect of different harvesting ages (12, 13, 14, 15, and 16 months) on yield and yield components of selected the two sugar cane varieties (B52/298 and NCo 334) grown in Finchaa sugar factory, Oromia, Ethiopia. A field experiment was conducted at Finchaa sugarcane plantation using a randomized complete block design of a factorial arrangement of 2 × 5 with three replications. The data were performed using SAS version 9.3, and a significant difference was considered at p ≤ 0.05 . The results showed that B52/298 variety had a higher estimated recoverable sucrose than NCo 334 variety. The results also indicated that as harvesting ages increase yield, yield components of sugar cane quality are increased. The maximum sugar yield of 1.89-ton ha-1 month-1 was obtained at the harvesting age of 15 months. There was a significant difference ( p < 0.05 ) between harvesting age and sugarcane varieties on cane yield, sugar yield, brix percent juice, pol percent, and recoverable sugar. Generally, the findings imply that as harvesting ages in month increase, brix percent juice, estimated recoverable sucrose, and sucrose percentage in both varieties were simultaneously increased. The findings suggested that B52/298 sugar cane variety with harvesting age between 14 and 16 is highly recommended to obtain optimum sugar cane yield and yield components at the tropical areas of Finchaa sugar factory.

Sugarcane stalk population is a key determinant of cane yield and knowing the right intra-row spacing is a critical factor in sugarcane production for a given environment. Therefore, a field experiment was conducted at Omo Kuraz Sugar Estate during the 2018/ 2019 cropping season to determine the effect of intra-row spacings (5 cm overlapping, end-to-end, 5 cm spacing between setts and 10 cm spacing between setts) on growth, yield, yield components and quality parameters of sugarcane varieties (N14, Mex54/245 and C86/112). The treatments were arranged in a split-plot design with three replications. Varieties were represented as the main plot whereas setts spacing treatments were assigned to sub-plots. Analysis of variance revealed that the intra-row spacing effect didn’t show a significant difference in the number of tillers, plant population, millable cane, cane yield, sugar yield, and Brix percent whereas significant (P<0.05) differences were observed in stalk height, stalk girth, number of internodes and weight per stalk. Therefore, the 10 cm intra-row spacing of three budded setts can be recommended for better productivity and profitability of N14 and Mex54/245 varieties at the Omo Kuraz Sugar factory.

Yield And Yield Components

In Malawi the demand of the use of mineral acidifying fertilizer by farmers for sustenance of high crop yields is increasing. The soaring demand is a pointer to the loss of humic substances in the soil and the resultant poor soil health. There is potential however to reduce the amount of mineral fertilizer used by the farmers and retain the applied nutrients within the plants rooting zone for increased use efficiency and productivity. This could be achieved through the combined application of humate based fertilizers with mineral fertilizer. Therefore, an experiment was conducted to evaluate the effect of different rates of NPK and humate based fertilizer (HBF) combinations on potato yield and yield components at Tsangano, Bembeke and Dwale Extension Planning Area (EPA) in the 2016/2017 cropping season. Ten treatments were laid out in a randomized complete block design (RCBD). Baseline soil data were collected and subjected to standard laboratory analytical procedure. Agronomic data collected in the experiment were analyzed in Genstat Discovery Edition 4 and were subjected to analysis of variance (ANOVA) at 95% level of confidence. The means were separated by the least significant difference (LSD0.05). Laboratory analysis showed that soils were strongly acid at the three sites with low amount of N, P, K except for Dwale EPA which had high P and medium content of K. Furthermore, results showed that different NPK and HBF combination significantly influenced potato tuber yield and yield components at the three sites. The recommended fertilizer rate of NPK 8:18:15 + 6S at 250 kg ha-1 + 60 kg N ha-1 produced the highest tuber yield at Tsangano (20,729 kg ha-1) and Bembeke (5,189 kg ha-1). At Dwale EPA, application of NPK 8:18:15 + 6S at 250 kg ha-1 produced the highest yield (13,956 kg ha-1). Nevertheless, different combinations of NPK and HBF fertilizer (Treatments 7, 8, 9 and 10) also gave comparably high yields and high number of big tubers. Therefore, the combined application of mineral fertilizer and humate based fertilizer potentially could increase potato yield in Malawi, sustainably. More studies however are required in order to confirm the results.

In order to determine the effects of sowing date on physiological characteristics, yield and yield components of six sweet maize hybrids, an experiment was arranged in split plot based complete randomized block design with three replications. Sowing date in two levels (15 June and 1 July) and sweet maize hybrids in six variants (‘Chase’, ‘Temptation’, ‘Challenger’, ‘Basin’, ‘Obsession’ and ‘Ksc403su’) were the treatments. Results of ANOVA revealed significant difference of sowing date and sweet maize hybrids on the number of days for tassel emergence, number of days to anthesis, plant height, cob height, stem diameter, plant dry weight, cob dry weight, number of grain rows, length flowers, number of leaf above the cob, raffinose content of grain and grain yield. Mean comparisons showed that the highest grain yield was obtained for ‘Basin’ variety and it was obtained from the crop established on the 15th of June as planting date. In temperate regions, maize potential productivity seems to be more limited by the amount of solar radiation available around silking (determinant of grain set) than during grain filling (determinant of grain weight).

<p>ABSTRACT<br />The level of sugarcane yield in dry land or rainfed generally still low at 40 to 50 tons per hectare. Farmers prefer maintenance of sugarcane than unloading ratoon cane (RC). This can be understood because unloading RC requires high cost, especially in the purchase of seed cane and tillage. Approach through maintaining ratoon techniques are expected to increase production and sugar yield. The research purposes to obtain cane yield and sugar yield RC optimally with maintaining ratoon techniques in dry land. Research has conducted in the Ngimbang, Lamongan district from June 2013 until August 2014. Sugarcane varieties used PS 862 (early ripening) belong to farmers. The study compiled by randomized block design (RBD) and repeated 3 times. The treatment consisted of 1). Replanting; 2). Off barring; 3). Organic fertilizer; 4). Maintaining 10 plants/m; 5). Giving PGR; 6). The package of (1+2); 7). The package of (1+2+3); 8). The package of (1+2+3+4); 9). The package of (1+2+3+4+5); and 10). Control. The results showed that the complete treatment of maintaining ratoon (replanting, off barring, organic fertilizer, maintaining 10 plants/m and PGR) obtained the highest value on the highgrowth parameters include 304.67 cm and a diameter of 3.16 cm, while the production parameters include the stalk number 5.73 stalk/m, stalk weight 1.29 kg/stalk, and stalk length 264.11 cm. Maintaining ratoon could gave the best cane yield and sugar yield than ratoon plants without maintaining ratoon cane with an increase of cane yield 16.20 tons/ha (32.14%) and an increase of sugar yield 1.38% (25.60%). Maintaining on ratoon cane 4th on rainfed significantly increase the production of sugarcane per hectare although not linear with increasing sugar yield.<br />Keywords: Maintaining ratoon, PS 862 varieties, dry land, Sacharrum officinarum</p><p> </p><p>PENINGKATAN PRODUKSI DAN RENDEMEN TEBU (Sacharrum officinarum) MELALUI RAWAT RATOON</p><p>ABSTRAK<br />Tingkat produktivitas tebu di lahan kering atau tadah hujan umumnya masih rendah sebesar 40 sampai dengan 50 ton per hektar. Para petani tebu lebih memilih rawat ratoon daripada membongkar tebu ratoon (RC). Hal tersebut dapat dipahami karena membongkar ratoon membutuhkan biaya yang lebih besar, terutama dalam pembelian bibit tebu dan olah tanah. Pendekatan melalui teknik rawat ratoon diharapkan dapat meningkatkan produksi dan rendemen tebu. Tujuan dari penelitian untuk memperoleh pertanaman tebu dengan teknik rawat ratoon yang berproduksi dan berendemen optimal di lahan kering. Penelitian dilaksanakan di Ngimbang, Kabupaten Lamongan mulai Juni 2013 sampai Agustus 2014. Varietas tebu yang digunakan yaitu PS 862 (masak awal) milik petani.

Teff is a major staple cereal crop in Ethiopia. However, its productivity is limited due to lack of appropriate sowing methods and utilization of improper seed rate are among the major once. Hence, a field experiment was conducted in Kiltu Kara District to determine the effects of seed rate and row spacing on yield and yield components of teff. Four levels of seed rates (10, 15, 20 and 25 kg ha-1) and three rows spacing (15, 20 and 25cm) used and combined 12 treatments in total. The experiment was laid out as a randomized complete block design with a factorial arrangement in three replications. All yield components teff were significantly affected by different row spacing except straw yields of teff. The interaction of seed rate and row spacing showed significant difference for yield and yield components of teff. Significantly higher mean values of teff were found by the interaction of 10 kg seed rate ha-1 and 25 cm row spacing. Significantly higher panicle length (36.9), number of tillers per plant (5), number of productive tillers per plant (4) of teff was recorded from interaction of 10 kg seed rate ha-1 and 25 cm row spacing. Higher dry biomass (2591 kg ha-1) and grain yields (1267 kg ha-1) of teff were recorded from interaction of 10 kg seed rate ha-1 and 25 cm row spacing. Mean of highest harvest index (49%) of teff was recorded from interaction of 10 kg seed rate ha-1 and 25cm row spacing as compared to others. Significantly higher straw yields (1488 kg ha-1) was recorded from interaction of 15kg seed rate ha-1 and 20 cm row spacing as compared to other treatment combinations. Therefore, the use of 10 kg seed rate ha-1 together with 25 cm row spacing was the optimum seed rate and row spacing and 10 kg ha-1 was profitable for the production of teff. To make definite conclusion further research for more seasons and location is required to give recommendation for the study area.

Abstract In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, iron and zinc spray on the yield and yield components of wheat, an experiment was carried out during the crop seasons of 2010 and 2011 on Shahid Salemi Farm in Ahwaz as a split factorial within randomized complete block design with three replications. The main plots with irrigation factor and three levels were considered: Level A) full irrigation, Level B) stopping irrigation at pollination step, and Level C) stopping irrigation at the seed filling stage. Subsidiary plots were considered with and without iron and zinc spray. Influencing the seed filling process, in interaction with iron, wich is an important leaf's chlorophyll cation, zinc increased the seed yield. The drought stress reduced the thousand kernels weight (TKW) and the number of seeds per spike increased about 24% and 8.5% more than the one of control treatment, respectively. Using iron, as compared with control treatment, causes the increase of thousand kernels weight from 45.71 to 46.83 grams and the increase of spike from 49.51 to 51.73. Zinc spray increased seed yield and thousand kernels weight. The results obtained from the present research showed that iron and zinc spray has fairly improved the effects caused by drought stress.

An experiment was carried out at Bangladesh Agricultural University, Mymensingh to evaluate the effect of urea super granule (USG) as a source of nitrogen on the yield and yield components of transplant Aman rice cv. BRRI dhan39, BRRI dhan46 and BINA dhan7. Five levels of N (viz., 0, 60, 120 kg ha-1 as prilled urea and 60 and 120 kg ha-1 as USG) were taken as experimental treatments. The experiment was laid out in a randomized complete block design with three replications. Plant height, effective tillers hill-1, grains panicle-1 and grain yield varied significantly due to different cultivars. All the yield and yield components except 1000-grain weight were influenced significantly by the levels of nitrogen fertilizer. The highest grain yield (4.82 t ha-1) was recorded in BINA dhan7 and the lowest one (4.30 t ha-1) was recorded in BRRI dhan39. Nitrogen @ 120 kg ha-1 as USG performed the best among the treatments in respect of yield and yield components of rice. The highest grain yield (5.46t ha-1) was obtained from BINA dhan7 with 120 kg N ha-1 as USG which was statistically identical with 60 kg N ha-1 as USG. A considerable amount (31.25%) of prilled urea (PU) nitrogen could be saved by using USG. It may be concluded that USG could be used as N management to achieve better nitrogen use efficiency in reducing N loss than the PU.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19095 Progress.

The experiment was conducted to evaluate growth and nitrogen uptake of the twelve sugarcane varieties, viz. NiF3, NiF8, Ni9, Ni12, Ni15, Ni17, Ni21, Ni22, Ni25, Ni27, Ni28, and Ni29, under rain-fed conditions during the period from 70 to 160 days after transplanting (DAT) at the experimental field, Faculty of Agriculture, University of the Ryukyus, Okinawa, Japan. The results showed that water shortage from a rain-fed condition caused reductions, but not significant in plant height and SPAD of sugarcane varieties. The genetic variation in leaf area, yield components, partial and total biomass, and cane yield was found among the investigated varieties. The positive associations between total nitrogen uptake with total biomass production and cane yield suggested that higher nitrogen uptake supports better growth performance of sugarcane under rain-fed conditions. From this study, NiF3 and Ni27 could be introduced as the promising sugarcane varieties for better growth performance and high nitrogen uptake under rain-fed conditions.

ABSTRACT<br />    <br />Sugar cane is a strategic commodity for the Indonesian government as raw material for the national sugar industry. Cultivation of sugar cane has been shifted to dry areas dominated by Inceptisol, Vertisol, and Ultisol soil. These conditions require certain clones to obtain high sugar yield. New improved varieties have been developed and 8 early-mid maturiting clones have been obtained. The study was aimed to evaluate and obtain earty-mid maturing clones with higher sugar yield than the existing varieties in dry land of Inceptisol soil. The study was conducted at the Karangploso Experimental Station, Malang from July 2015 to September 2016. The study was arranged in a randomized block design with three replications. The treatment consistsed of eight clones of early to mid maturing sugarcane clones and one control variety (Kenthung). The eight clones were (1) PS 04 117, (2) PS 04 259, (3) PS 04 129, (4) PS 05 258, (5) PS 06 391, (6) PS 06 370, (7) PS 06 188, and (8) JR 01. The results showed that three clones (PS 06 188, PS 05 258 and JR 01) produced higher sugar yield (10.45-11.88 ton ha-1), and the other clones showewd lower sugar yield (6.55-9.37 ton ha-1) than that of Kenthung variety (9.16 ton ha-1).PS 06 188 and PS 05 258 clones obtained the highest sugar yield of 11.88 and 11.49 ton ha-1, respectively.<br /><br />Keywords: dry land, performance, Saccharum officinarum,  sugar content, variety<br /><br />

Effect On Yield

An experiment was conducted to evaluate effect of urea fertilizer on yield and yield components of Zea mays L. Using Randomized Complete Block Design (RCBD) split plots in three replications in agricultural research farm of Balkh University by 2019. Doses of urea used in this experiment were 0, 80, 160 and 240 kg ha-1 , respectively. It has been found that amount of nitrogen fertilizer (urea) had significant effect on yield of maize at p<0.05. The higher level of nitrogen caused the higher grain yield, number of kernels per ear, the number of grains per ear row, ear diameter, cob length, grain per plant and plant height. As a result 7.76 ton ha-1 was recorded as high yield while 240 kg ha-1 urea was used, and 5.12 ton ha-1 was recorded as low yield in treatment one with 0 kg ha-1 of nitrogen fertilizer. Finally, as a result using 240 kg ha-1 nitrogen fertilizer is recommended.
