Peanut (Arachis hypogaea)  is commonly grown during the dry season and most farmers used the native variety. Growth retardants such as paclobutrazol (PBZ) was found to increase yield of some important crops. A study was conducted to determine the effect of different levels of paclobutrazol on the peanut yield of Asha and Farmers’ variety during the wet season. The experimental area was laid out using Randomized Complete Block Design (RCBD) factorial. Treatments were replicated thrice. Data were analyzed by Analysis of Variance (ANOVA) and  the Honest Significant Difference (HSD) test was used to compare treatment means. The increasing level of PBZ increased the number of pods of Asha by 29.97% while the most number of seeds was obtained from farmers’ variety. Applied PBZ Asha at 150mg/L recorded the highest shelling percentage that is 16.19% higher when compared to the untreated. Paclobutrazol application significantly increased seed yield of Asha and farmers’ variety by 43.34% and 20.86% at 150mg/L and 75mg/L, respectively. The increase in yield was due to the observed reduction in plant height and stem growth which possibly enhanced assimilate partitioning to pods. Asha applied with PBZ at 150mg/L obtained the highest seed yield of 4.2 tons/ha. Keywords— Agriculture, yield, peanut, paclobutrazol, experimental design, Pampanga, Philippines

An experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, Bangladesh to evaluate the influence of fertilizer-N on biochemical characteristics, nutrient accumulation and yield of potatoes during the period from November 2002 to March 2003. Two varieties, namely Cardinal and Diamant and five levels of N viz. 0, 100, 125, 150 and 175 kg ha-1 were applied in a factorial randomized complete block design with three replications. The results indicated that the biochemical characteristics, nutrient concentrations, yield components and yield were significantly influenced by the different levels of N. The nitrate reductase activity, chlorophyll content, total free amino acid showed positive linear relationship with different doses of N-fertilizers. The highest tuber weight and nitrogen accumulation were found from the plants which received 150 kg N ha-1. Application of 150 kg N ha-1 resulted in best biochemical characteristics, nutrient uptake, yield and yield components of potato varieties- Cardinal and Diament.

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 region of the Zona da Mata of Minas Gerais stands out in the production of vegetables. To achieve the success in this activity, it is important to choose suitable cultivars and apply irrigation correctly. This study aimed to determine the optimum irrigation depth and evaluate new commercial arugula cultivars in the Zona da Mata of Minas Gerais. The cultivation was carried out in a greenhouse during three cycles with periods of 33 (January 11, 2016 to February 12, 2016), 36 (March 1, 2016 to April 5, 2016), and 36 (April 12, 2016 to May 17, 2016) days. The experimental design was a randomized complete block design with five replications, five irrigation depths (50, 75, 100, 125, and 150% of the crop evapotranspiration-ETc) in the plots, and three arugula cultivars (Antonella, Cultivada, and Folha Larga) in the subplots. A drip irrigation system was used. The parameters evaluated were root depth, root fresh mass, plant water potential, leaf temperature, number of commercial leaves, total number of plants, fresh shoot mass, and water use efficiency. Arugula cultivars did not present differences in their agronomic characteristics. An irrigation depth of the 50% ETc is recommended if the soil moisture is under the field capacity at the beginning of the arugula cycle.

Abstract The objective of this study was to determinate the effects of narasin on carcass characteristics of lambs fed a diet containing different levels. Forty-four lambs were allotted in a randomized complete block design, defined by initial body weight (BW), in a 2x2 factorial arrangement. The first factor was forage (coastcross hay) inclusion (10 or 20%, DM basis) and the second factor was narasin (0 or 13 ppm). The experimental diets were isonitrogenous (17.4%, DM basis). The experiment lasted 112 days. At the end of the experiment, the lambs were slaughtered to evaluate the carcass characteristics and meat composition. Data were analyzed using the MIXED procedure of SAS and the LSMEANS option was used to obtain the means. The effects were considered significant when P < 0.05. There was no interaction between forage levels and narasin inclusion. The experimental diets did not affect the slaughter BW (54.8 ± 1.6 kg), hot carcass weight (29.3 ± 0.96 kg), dressing percentage (53.5 ± 0.67%) and LM area (18.8 ± 0.89 cm2). The inclusion of narasin increased 12th-rib fat (2.10 vs 2.75 mm; P < 0.01) and BW thickness (16.9 vs 20.2 mm; P < 0.01). The inclusion of 20% of hay decreased BW thickness (19.21 vs 17.9 mm; P = 0.03). The experimental diets did not affect the moisture (74.2 ± 0.53%) and ash content in meat (1.27 ± 0.04%). Narasin inclusion increased the fat (2.81 vs 3.62%; P < 0.01) and decreased the CP (21.3 vs 20.7%; P = 0.02) in meat composition. The inclusion of 10% of hay increased the fat in meat (3.5 vs 2.9%; P = 0.03), however, did not affect the CP content. In conclusion, the narasin inclusion and levels of hay improve the carcass characteristics and change the meat composition.

Effect On Growth

Two experiments evaluated the Trevett (1972) Cu standard of 7 ppm by raising leaf Cu concentrations in a commercial blueberry field having low (∼4 ppm) leaf Cu concentrations. A foliar spray of Cu Keylate (5% Cu) (Stoller Enterprises, Inc.) in a volume of 627 L·ha-1 applied 0, 0.56 1.12, 1.68, or 2.24 kg·ha-1 of Cu. Ammonium sulfate at 3.1 kg·ha-1 was added to the solutions to enhance Cu absorption. A preemergent soil application of Micromate Calcium Fortified Mix (Stoller Enterprises, Inc.), a micronutrient mixture containing Cu (0.3%), was also tested at 14 kg·ha-1. These 6 treatments were replicated 7 times in a randomized complete-block design in 2001. Treatments were reapplied in 2003 in a split-plot design with Cu treatments as the main plots and an application of DAP at 448 kg·ha-1 as the split plots. In 2001, leaf Cu concentrations increased linearly, up to 12 ppm, with increasing rates of Cu, but Micromate had no effect. Leaf N and P concentrations were below the standards of 1.6% and 0.125%, respectively, and could explain why raising leaf Cu concentrations had no effect on growth or yield. In 2003, DAP corrected the N and P deficiency and leaf Cu concentrations were raised to above the 7 ppm standard with 2.24 kg·ha-1 of Cu, but again, no effect on growth or yield was found. The Cu standard appears to be too high.

An experiment was conducted at the Farmer’s Field, Boyra village, Mymensingh, Bangladesh during the period from February to May 2016 to study the yield performance of boro rice for seed production as influenced by nitrogen and phosphorus fertilization with different levels of roguing. The experiment comprised three levels of roguing viz. no roguing (R0), roguing one time (R1) and roguing two times (R2) and five doses of N and P fertilizers viz. Farmer practice (F1: 250 kg urea and 260 kg TSP), Optimum/recommended (F2: 187 kg urea and 200 kg TSP), High N (F3: 200 kg urea and 200 kg TSP), High P (F4: 187 kg urea and 240 kg TSP) and High N + High P (F5: 200 kg urea and 240 kg TSP). The experiment was laid out in a randomized complete block design with three replications. Results revealed that the Optimum doses of fertilizer applications significantly produced the highest grain yield among the treatments. All the yield contributing characters showed the best performance in this treatment. Though roguing did not produce significant yield variation but the interaction effects did. Here, The Optimum doses of fertilizer without roguing (F2R0) produced highest grain yield but it was at per with F3R1, F2R2, F2R1, F4R1 and F5R2 treatments. Among the five statistically alike treatments F2R2 i.e. optimum fertilizer dose with two rougings produced the highest number of filled grains per panicle and highest seed germination and appreciably higher percentage of pure seed. Based on this experimental result, it appears that optimum fertilizer dose with two times rouging treatment performed the best for seed production in BRRI dhan29.
