Aim: This study aimed to evaluate the   effect of different levels of nitrogen and filter mud cake applications on vegetative growth and yield on tomato cultivar "Castle Rock". Place and  Duration of Study: Field experiments were conducted during two successive winter seasons 2015/2016 and 2016/2017 at the experimental farm, Faculty of Agriculture and Natural Resources, University of Bakht Alruda, Ed Duiem, Sudan. Methodology: Treatments included three Nitrogen levels (0, 43 and 86 kg N/ ha) and three filter mud levels (0, 2 and 4 ton/ ha). Urea (46%N) was used as source of nitrogen and applied after fifteen days from sowing. Filter mud cake was applied one month before sowing. The treatments were arranged in a randomized complete block design with three replications. Results: Results showed significant differences among N treatments in tomato vegetative growth, yield and yield components in the two seasons. The 86 kg N/ ha showed the highest vegetative growth yield and yield components compared to control. The filter mud application at both rates showed significant increase in the most vegetative growth parameters, yield and yield components compared to the control in the two seasons. The combination of N and filter mud resulted in significant increase in vegetative growth and yield components, the highest values were obtained by application of 86 kg/ha combined with 4 ton filter mud /ha. Conclusion: Considering the present study it can be concluded  that the application of 86 kg/ha combined with 4 ton filter mud /ha  is the best level in terms of maximum vegetative growth, yield and yield components of Castle Rock tomato cultivar.

An experiment was conducted to study the effect of mulch (non-mulch and straw mulch) and different levels of nitrogen (0, 40, 80 and 120 kg ha-1) and potassium (0, 37.5, 75 and 112.5 kg ha-1) on the growth and yield of onion. Plants grown with straw mulch gave higher bulb yield (10.89 t ha-1) which showed 13.79% increase over non-mulch. Nitrogen increased the bulb yield significantly.The highest nitrogen level gave the highest bulb yield (12.13 t ha-1), which was 41.54% increase over control. Potassium increased bulb yield compared to control, but its different levels had identical results on yield. Nitrogen and mulch together produced significant variations. The Nitrogen at the highest level (120 kg ha-1) along with straw mulch gave the highest yield (13.31 t ha-1). Potassium together with mulch also exhibited significant variation on yield and yield components. Plants grown with the highest level of potassium (112.5 kg ha-1) along with straw mulch gave the highest bulb yield (11.58 t ha-1). Nitrogen and potassium as 120 kg N ha-1 × 75.0 kg K ha-1 gave the highest bulb yield (13.07 t ha-1). Nitrogen and potassium at their maximum levels with straw mulch gave the highest bulb yield (14.67 t ha-1).DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16747 Progress. Agric. 21(1 & 2): 39 - 46, 2010

Yield And Yield Components

SUMMARYThe effects of intercropping, mulching and staking on growth and yield of three tomato varieties were evaluated in four field trials in 1982 and 1983. Fruit yields of the improved varieties were significantly reduced by intercropping with okra but the yield of a local variety was unaffected. Though the yield of okra when grown with tomato varieties was less than that of a sole crop, the combined yield of the two crops in mixtures was more than the means of the species in monoculture. Relative Yield Totals (RYT) increased to maxima of about 1.42 and 1.39 when the local variety was grown with okra in 1982 and 1983 trials, respectively. Mulching and staking significantly increased vegetative growth, yield and yield components of the tomato plants. Mulched plants grew taller and had more branches and a greater number and weight of fruits than staked plants. Improved varieties responded better to mulching and staking than the local variety. Growing improved varieties of tomato in sole stands with proper mulching and staking is therefore recommended.

Pot Culture

A pot culture and a field experiment were conducted with cyanobacteria in presence and absence of different levels of urea to evaluate their effects on growth and yield of rice cv. BRRI Dhan 28, 29 and 36 during Boro season of 2007. The treatments were T1 (control), T2 (only cyanobacteria), T3 (recommended doses of urea - 60 kg N/ha), T4 (45% recommended doses of urea + cyanobacteria), T5 (65% recommended doses of urea + cyanobacteria) and T6 (85% recommended doses of urea + cyanobacteria).The maximum values for different growth, yield and yield components (plant height, number of productive tillers/hill, panicle length, number of grains/panicle, 1000-grain weight, and grain, straw and biological yield) were observed in BRRI Dhan 29 under T6 (85% recommended doses of urea + cyanobacteria) and lowest was observed in BRRI Dhan 28 under T1 (neither urea nor cyanobacteria). Uses of cyanobacteria increased the yield of Boro rice varieties and decreased the use of urea by 15-20%.

Yield And Yield Components

Greenhouse and field experiments were conducted to determine the influence of transplant age on growth and yield of `Dixie' and `Senator' summer squash (Cucurbita pepo L.). Dry weight and leaf area measurements indicated that 28- to 35-day-old greenhouse-grown transplants grew more slowly after transplanting than plants that were 10, 14, or 21 days old. Older transplants flowered earlier; however, earlier flowering did not result in higher early yields. Transplants of varying ages did not differ greatly in yield and yield components in the field, although all transplants had higher early yields than the directly seeded controls. Results from these experiments suggest that 21 days may be a reasonable target age for transplanting summer squash. If transplanting were delayed by adverse planting conditions, 21-day-old transplants would likely have at least a 10-day window of flexibility before yields would be reduced notably by additional aging.

A field experiment was conducted during the kharif, 2018 to study the effect of Nova Aminochelated-Zinc on growth, yield and yield components of rice. The experiment was laid out in Randomized Block Design with six treatments T1: Control, T2: Recommended Dose of Fertilizers (RDF) without Zinc, T3: T2+5 ml l-1 Nova Ami-Zinc @TI and PI, T4:T2+2.5 gm l-1 ZnSO4 @TI and PI, T5: 5 ml l-1 Nova Ami-Zinc @TI and PI, T6: 2.5 gm l-1 ZnSO4 @TI and PI. Experiment revealed that application of RDF+5ml l-1 Nova Ami-Zinc @ TI and PI (T3) resulted in maximum Number of tillers m-2, Total number of Grains Panicle-1, Number of Filled Grains Panicle-1, Test weight and Grain Yield but application of RDF+2.5 gm l-1 ZnSO4 @TI and PI showed maximum height followed by application of RDF +5 ml l-1 Nova Ami-Zinc @ TI and PI.
