Studies were conducted at the Fortuna Substation for 10 years to determine the effect of 5 interstems on growth and yield components of 2 commercial mango varieties. The interstems did not significantly affect the rootstock diameter when Edward variety was the scion; however, they did with Palmer variety as scion at the 3- and 6-year stages only, Irwin interstem diameter at the 3-year stage for Edward and Palmer, and at the 6- and 9-year stages for Edward, was significantly thicker than that of the other interstems. Edward on Manzano Tetenené had the thinnest interstems. In the two varieties studied, the scion diameter was scarcely affected by the interstems at 3, 6 and 9 years after transplanting. Edward and Palmer grafted on Irwin as interstems had significantly lower scion/interstem ratios. The opposite was true when these varieties were grafted on Julie. Three years after planting, the smallest trees were those of Edward and Palmer grafted on Malda; 6 and 9 years after planting, those of Edward grafted on Malda and Manzano Tetenené. Yield efficiency decreased significantly with tree age and size. Thus, there was a negative correlation between these parameters. Edward produced significantly more fruits than Palmer at the 3-year-old stage. Edward as interstem grafted on Eldon produced significantly more fruits at the 3-, 6- and 9-year stages than when grafted on the other interstems. Palmer grafted on Eldon was significantly more precocious than when grafted on the other interstems. Malda and Manzano Tetenené as interstems significantly reduced tree size of Edward; Julie as interstem reduced the size of Palmer.

The research aimed to study effect the application of river sand (RS), coconut coir (CC), and banana coir (BC) on growth and yield of rice (Oryza sativa L.) in Ustic Endoaquert. The research was carried out in a green house using 3 × 3 × 3 factorial design. The RS factor consists of three treatment levels which were 0% RS, 25% RS, and 50% RS. Meanwhile, the CC and BC consist of three treatment levels, where each level were 0 Mg ha-1, 10 Mg ha-1 and 20 Mg ha-1. The results showed that RS, CC and BC applications did not have significant effect on plant height. On the other hand, all ameliorant applications had significantly increase leaf length and the highest percentage increasing was in BC (13.49%). The leaf numbers and tiller numbers had relatively similar pattern, except BC that had significantly increased leaf numbers by 77.69% and amount of tiller numbers by 49.45%. Furthermore, for yield components, RS, CC and BC applications had significant increased panicle numbers by 37.76%. It was only RS and BC that increased panicle lenght and the best increasing of 26.82% on RS. Meanwhile, the BC application only increased the rice grain numbers.[How to Cite: Nurdin and F Zakaria. 2013.

The effect of foliar application of commercial seaweed extract on potato growth was studied in long-day conditions (60° 10' N 25°00' E) characterized by a cool and short growing season. The results showed that neither the doses, 0, 5, 10, 20 l/ha nor the spraying 24, 45, 58 days after the emergence had any remarkable influence on potato growth and yield if the other preconditions of production are in order. Only small, although insignificant benefit could be obtained with application done three weeks after emergence, clearly before tuber initiation.

Alfalfa has a great need for water, because it creates a huge plant mass. For this reason,yield level, similar to the other species with large green mass, primarily depends onprovided water during the growing season. Alfalfa uses water well from the prevegetationreserve in land, especially of rainfall during the growing season. In thispaper, the need for water in alfalfa for average, the most rainy and dry hydrologicalyear in the conditions of Sarajevo area was established. Evapotranspiration of alfalfa is567 mm for the most dry, 569 mm for the most rainy and 540 mm for averagehydrological year. Water deficit occurs in May, June, July and August in the amount of323.9 mm for the most dry, 178.4 mm for the most rainy and 222.1 mm for averagehydrological year. In the study area, alluvial soil is predominant (fluvisol), which is ofa light mechanical composition (sandy loam) and favorable chemical characteristics foralfalfa growing.

[GROWTH APPEARANCE AND YIELD OF FIVE TOMATO HYBRIDS ON ULTISOL AND PEATLANDS].  Ultisol and peat are included in marginal land that can support the growth and development of plants. This study was aimed to compare the growth and yield of five tomato hybrids on ultisol and peatlands. The experiments were carried out in the field with the soil type of on ultisol and peats.  The experiment was arranged in a Randomized Completely Block Design with 3 replications. The hybrids evaluated were UNB-1 × UNB-2, UNB-3 × UNB-1, UNB-2 × UNB-1, and UNB-2 × UNB-3, and Sinta as a control hybrid.  The results showed that in ultisol lands, the diversities among genotypes were observed in some variables, including the age of flowering, a number of fruits per plant, fruit diameter, fruit weight per plant, and fruit sweetness level.  On the peatlands, a significant diversity was observed in plant height, age of flowering, age of harvest, fruit weight per plant, number of flowers per bunch. Based on this evaluation in the Ultisol soil, the yield of UNB2 × UNB1 was higher than control (Sinta genotype), whereas, in peat, the growth and yield components of UNB2 × UNB3 is the best and Sinta hybrid as a control genotypes showed the highest yield among other genotypes.

ABSTRACT Weed competition on soybean (Glycine max) growth and yield was expected to be different when managed in an agroforestry system as compared with sole-cropping without trees. Therefore agronomic practices to control weeds might need to be modified in agroforestry systems. We analyzed weed competition effects on soybean growth, grain yield, and yield components at different distances from 4year-old eucalyptus (Eucalyptus benthamii) in an alley cropping system, as well as in a sole-crop system in southern Brazil. Above-ground soybean biomass was collected throughout the growing season and a logistic function was used to model crop growth. Weed above-ground biomass sampled during the soybean cycle, and grain yield and yield components at the end of the growing season were evaluated using regression analysis across positions between tree lines, and results compared to those without influence of trees. Soybean yield components were mostly reduced between tree lines compared with sole-cropping without trees. Soybean growth and yield within the eucalyptus agroforestry system was not affected by weed competition. However, weeds reduced soybean growth and yield in sole-cropping without trees. Reduction in soybean yield in the agroforestry system was rather caused by competition from trees. Therefore, tree interference may limit both weed and soybean growth potential.

The spatial and temporal variations in soil water play a key role when considering issues such as irrigation and drainage requirements, crop growth and yield potential and contamination of groundwater by agricultural chemicals. In this study a previously validated deterministic model was used to estimate water (evapotranspiration) deficits and surpluses during the growing season of a perennial forage crop at 14 locations in Ontario. Three different hydraulic soil profile characteristics, representing a clay, clay loam and sandy loam soil, and three different lower boundary conditions (free drainage, fixed and fluctuating water table) were considered. Seasonal deficits ranged from less than 15 mm in abnormally wet years (90% probability of exceedence) in the north, to more than 300 mm in exceptionally dry years (5% probability of exceedence) in the extreme southwest region of the province. With a water table fluctuating between 25 cm depth during the middle of April and 140 cm in early October, 28 to 49% of the evapotranspiration deficit was caused by excess water in all three soils. The flux of water at 100 cm depth, accumulated during the growing season, was used as a measure of the net amount of surplus water moving through the root zone or being extracted from the water table. This flux ranged from significant upward values in dry years in a sandy loam with a fixed water table at 120 cm depth, to downward fluxes of more than 300 mm in abnormally wet years when a fluctuating water table was present. Our simulations show important spatial and temporal interactions among soil and climatic factors and suggest that each one, including the lower boundary condition, should be properly characterized in soil water investigations.

The experiment was conducted during kharif II in 2006 & 07, rabi in 2006-07 & 07-08 and kharif I in 2007 and 2008 at ARS, Burirhat, Rangpur in RCB design to understand the influence of season and location specific environment effect on growth and yield of hybrid maize and selected suitable variety(s). Four hybrid maize varieties V1=BARI hybrid Maize (BHM)-2, V2=BHM-3, V3= BHM-5 and V4= Pacific-984 (as check) were tested during kharif II in 2006 while seven varieties V1= BHM-2, V2= BHM-3, V3= BHM-5 and V4= Pacific-984, V5= Pacific-60, V6= Pacific-11 and V7= Prolin were during the other seasons except rabi, 07- 08, where variety Pacific-555 was used in V7 instead of Prolin. Seeds were sown on August 30 and August 11 for kharif II of 2006 and 2007, respectively, November 28 and 17 for rabi 2006-2007 and 2007-08 and March 08 and 12 for for kharif I 2007 and 2008. The crops were harvested on January 25, 2007 and January 12, 2008 in the two consecutive kharif II seasons; May 10 and April 29 in rabi 2006-07 and 2007-08, and July 01 and 05 in kharif I 2007 and 2008, respectively. Yield parameters were mostly varied significantly. The highest yield was obtained from BHM-5 (9.03 t ha-1), which was followed by Pacific-984 (8.89 t ha-1), BHM-3 (8.81 t ha-1) and BHM-2 (8.58 t ha-1) in kharif II, 2006 while in kharif II, 2007 the highest significant yield was noted in Pacific-984 (9.22 t ha-1). In rabi, 2006-07, significant highest grain yield was obtained from Pacific-60 (11.03 t ha-1), which was statistically identical with Prolin (10.20 t ha-1). The yield of Prolin was also statistically identical with Pacific-11 (10.01 t ha-1), BHM-5 (10.00 t ha-1), BHM-3 (9.92 t ha-1) and BHM-2 (9.51 t ha-1). Comparatively lower temperature during ear initiation (mean 29.6°C in rabi and 31°C in kharif II) and silking (mean 18.2°C in rabi and 20.2°C in kharif II) contributed much for higher trend of yield in rabi over kharif. In kharif I, 2007, the highest yield (9.55 t ha-1) was recorded from Pacific-60, which was identical to Pacific-984 (9.25 t ha-1), BHM-5 (9.11 t ha-1) and BHM-3 (8.89 t ha-1). All the BARI hybrid maize varieties were suitable to grown in kharif I, kharif II and rabi season although BHM-3, BHM-5, Pacific-60 and Pacific-984 were better in Kharif I and Pacific-60, BHM-5, Prolin and Pacific-555 were found better in Rabi season.
