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

Background: Water scarcity is one of the major problems faced by farmers for crop production. Productivity and sustainability of a crop like wheat which is highly susceptible to water stress could be affected the most. Identifying and growing such varieties of wheat which could thrive under restricted irrigation could solve the problem. The current study aimed to evaluate the performance of certain new wheat genotypes under restricted irrigation.Methods: A field experiment was conducted in eastern sub-Himalayan plains during Rabi season, 2016-2017 to evaluate the performance of certain wheat genotypes under restricted irrigation. The experiment was laid out in a split plot design with three different levels of irrigation, viz., no irrigation, one irrigation at CRI stage, two irrigations at CRI and booting stage, randomly allotted in main plots; while six genotypes comprising HI 1612, HD 2888, C 306, K 8027, HD 3171 and K 1317 were randomly allocated in sub plots.Result: It was observed that with increase in number of irrigation, the overall biomass production increased irrespective of genotypes. The highest biomass (7.38 t ha-1) was achieved in plots where two irrigations were given. Higher leaf area with increased plant height and tiller number as well as higher values of major yield components viz., number of spikes m-2 and number of filled grain spike-1 were also achieved in plots receiving two irrigations. The twice irrigated plot also exhibited higher yields (3.02 t ha-1) as compared to once irrigated plot. With increase in number of irrigation the grain yield increased significantly. Among the genotypes, HI 1612 reflected the maximum grain yield (2.76 t ha-1) under restricted irrigation though there was no significant variation in grain yield achieved with the other 5 genotypes except HD 3171.

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.

Three popular tomato varieties namely, Ratan, BARI tomato-3 and BARI tomato-6 were experimentally evaluated to identify the potential mulch on growth and yield, where the experiment consisted of four mulching treatments viz. water hyacinth, straw, am-ada leaf and banana leaf with a control (no mulch). The experiment was conducted under rainfed condition. In the experiment, mulching showed significant effect on growth, yield components and thus on the yield of tomato. Yield contributing characters were significantly higher when water hyacinth mulch was used. The variety Ratan produced the highest (53.74 t/ha) fruit yield, while BARI tomato-3 showed the lowest (48.89 t/ha) fruit yield. The combination of mulching and variety exhibited significant variation in some yield components and yield. The combination of water hyacinth and Ratan produced the maximum yield (62.16 t/ha) and thus the experiment revealed that water hyacinth and straw mulches have potentiality to increase the yield of tomato.

An experiment was conducted to assess the yield and yield components of QPM genotypes to plant population under irrigated conditions in a semi arid ecology of Northern Nigeria. Field trials were conducted at the Irrigation Research Station, Institute for Agricultural Research, Kadawa (11° 39'N, 08° 20'E) and 500 m above sea level) during dry seasons 2007, 2008 and 2009 to study the effect of (Zea mays L.) genotypes (TZE-W Pop X 1368, EV-DT W99 STR and DMR-ESRW), four plant population (33333, 44444, 55555 and 66666 plants ha-1) and three irrigation scheduling (40, 60 and 80 centibars soil moisture tension) on the growth and yield of quality protein maize. A split plot design was used with combinations of genotypes and irrigation regimes assigned to the main plot and plant population assigned to the sub-plot. The treatments were replicated three times. The study revealed that genotype EV-DT W99 STR had significantly higher weight of ears per plant, cob length, cob diameter, number of rows per cob, 100 grain weight, grain yield, shelling percentage and harvest index than the other two genotypes used in the trial. Irrigating at 40 and 60 centibars significantly increased weight of ears per plant, while delayed irrigation significantly depressed total dry matter production. Based on the results obtained in this study, it can be concluded that the use of genotype EV-DT W99 STR, at 60 centibars irrigation scheduling and population of 55,555 plants ha-1 had resulted in good agro-physiological characters of QPM at Kadawa.

The experiment was conducted at the Agronomy Field laboratory, Department of Agronomy and Agricultural Extension, University of Rajshahi to study the yield and yield components of wheat as affected by phosphorus fertilization. The experiment consisted of two factors i.e. (i) three wheat varieties viz., Shatabdi, Bijoy and Prodip and (ii) five levels of phosphorus viz. 0, 30, 60, 90, 120 kg P2O5 ha-1. A RCBD design was used for the experiment with three replications. The effect of variety was significant on all the yield components and yield except plant height. Prodip gave the highest grain yield (3.67 t ha-1) followed by Bijoy (3.45 t ha-1) and Shatabdi (3.28 t ha-1). Yield and yield components of wheat were significantly influenced by different levels of phosphorus. The highest grain yield (4.47 t ha-1) was recorded from P4 (120 kg P2O5 ha-1) and the lowest one (2.43 t ha-1) from the control treatment. The highest grain yield (4.80 t ha-1) was obtained from Prodip at 120 kg P2O5 ha-1 and the lowest one (2.3 t ha-1) was found in Shatabdi at control treatment. The results suggest that the combination of V3P4 (Prodip with 120 kg P2O5 ha-1) is the best for obtaining higher yield of wheat.
