Field experiments were conducted during Kharif-2017 and 2018 at ICAR-Krishi Vigyan Kendra (KVK), Mangaluru of coastal Karnataka to study the effect of integration of organic and inorganic sources of nitrogen on the yield of midland rice. The results indicated that the integration of organic and inorganic sources of nitrogen significantly influenced the growth and yield attributes of rice. The highest grain yield (5434 and 5372 kg ha-1) and straw yield (6817 and 6927 kg ha-1) were recorded in the treatment comprising VC substituted with 50 percent recommended dose of nitrogen which was on par with PM substituted at 50 percent in both the years. A similar trend was also noticed in both the years for the growth and yield parameters where the highest plant height (94.93 and 96.30 cm) highest productive tillers (16.85 and 18.12) and longer panicle length (17.54 and 18.65 cm) was recorded in the treatment where 50 percent nitrogen was substituted by vermicompost compared to control. The remaining treatments of organic substitution ratios with urea also had a beneficial effect on yield and yield parameters of rice compared to control.

ABSTRACT The objective was to evaluate the growth and yield of sugarcane irrigated with brackish water and leaching fractions. A completely randomized experimental design was used, in a 5 x 2 factorial scheme, with four replicates. The treatments consisted of five irrigation water salinity levels (0.5, 2.0, 3.5, 5.0 and 6.5 dS m-1) and two leaching fractions (0 and 0.17), corresponding to 100 and 120% of the crop evapotranspiration. The irrigation management was performed daily. Irrigation water salinity levels were obtained by adding NaCl and CaCl2 to the public-supply water, in order to obtain a molar ratio between Na:Ca of 1:1. The following measurements were taken: height and stem diameter; number of tillers; number of leaves and leaf area with monthly frequency between 60 and 300 days after planting (DAP). It was concluded that irrigation water salinity negatively influenced the variables of growth and yield in the sugarcane, and the leaching fraction of 0.17 was capable of reducing the deleterious effects of the salts on the plants.

Irrigation Water Salinity

Response of wheat (Triticum aestivum L., cv. Shatabdi) to irrigation water of five salinity levels was investigated at the Bangladesh Agricultural University (BAU) farm with a view to search for a possible advantageous salinity level for the crop. The experiment comprised five treatments ? I1: irrigation by fresh water of background salinity 0.385 dS m?1 (control) and I2 ? I5: irrigation by synthetic saline water (prepared by mixing sodium chloride salt with fresh water) of electrical conductivity (EC) 4, 7, 10 and 13 dS m?1 (at 25oC), respectively. Wheat was grown under three irrigations applied at maximum tillering, booting and milking/grain filling stages, and with recommended fertilizer dose. Irrigation water of EC ?10 dS m?1 significantly (p = 0.05) suppressed most growth and yield attributes, and yield of wheat compared to irrigation by fresh water (I1). An attention-grabbing observation was that irrigation by saline water of 4 dS m?1 (I2) contributed positively to the crop attributes. Leaf area index (LAI), spike length, spikelets and grains per spike, 1000-grain weight and above ground dry matter (ADM) of wheat increased by 1.9?3.4, 0.9, 2.6, 7.4, 2.1 and 2.8?6.0%, respectively in I2 compared to the control. The improvement in the LAI and ADM in I2 was significant over I1. Because of the largest spike density, the utmost grain (3.85 t ha?1), straw (5.09 t ha?1) and biomass (8.93 t ha?1) yields of wheat were however obtained under I1. The proposition of the advantageous irrigation water salinity level of 4 dS m?1 thus warrants further investigation DOI: http://dx.doi.org/10.3329/jbau.v11i1.18225 J. Bangladesh Agril.

Irrigation Water Salinity

The effects of irrigation water salinity (12 dS m?1), imposed at maximum tillering (35?40 days after sowing, DAS) or booting (50?60 DAS) or grain filling (75?85 DAS) stage of wheat, on growth and yield of the crop was demonstrated. The experiment comprised four treatments – I1: irrigation by fresh water (FW) at all three growth stages (control), I2: irrigation by saline water (SW) at maximum tillering stage and by FW at other stages, I3: irrigation by SW at booting stage and by FW at other stages, and I4: irrigation by SW at grain filling stage and by FW at other stages. The experiment was set in a randomized complete block with three replications. Wheat was grown under three irrigations (each of 3 cm) and recommended fertilizer doses (120 kg N, 32 kg P, 62 kg K, 20 kg S, 3 kg Zn and 1 kg B ha?1). Salinity of irrigation water imposed, separately, at the three growth stages did not impart significant (p = 0.05) negative influence on plant height, spike density, spike length, spikelets and grains per spike and 1000-grain weight. It, however, significantly hindered leaf area index (LAI), above ground dry matter (ADM), grain and straw yields, grain-straw ratio and water productivity of the crop. The least grain (3.622 t ha?1) and straw (5.772 t ha?1) yields, LAI (1.24 and 2.18 at 50 and 70 DAS, respectively), ADM (0.80, 4.78 and 7.66 t ha?1) and water productivity (186.5 and 297.3 kg ha?1 cm?1) obtained under I3 implied that salinity of irrigation water imposed at booting stage exerted the maximum retarding effects on the growth and yield of wheat. Grain yield decreased by 13.4% in I3 over the control, I1. An increase in grain and biomass yields by 14.3 and 11.9%, respectively under I2 over I1 demonstrated a positive contribution of irrigation water salinity imposed at maximum tillering stage of wheat.

Main Plot

Poor agronomic practices coupled with herbicide mismanagement influence crop performance, yield, weed infestation and environmental hazards. Thus, field experiments were carried out to investigate the effect of spacing and reduced levels of butachlor on weed control and yield of NERICA 1 rice (Oryza sativa L. x Oryza glaberrima L). The experiments were conducted in the 2011 rainy season at the Teaching and Research Farm of the Department of Crop Production and Horticulture, Modibbo Adama University of Technology, Yola, and Lake Gerio, Yola in the 2012 dry season. Yola is located between latitude 9o14? N and longitude 12o28? E in the Northern Guinea Savanna ecological zone of Nigeria. Treatments consisted of four spacings (20 cm x 20 cm, etc.) and four butachlor levels (3, 2, 1, and 0 kg ha-1 a.i.). The experiments were laid out in a split-plot design with spacings assigned to the main plot and butachlor levels assigned to the sub-plot and were replicated three times. Data were taken on percentage establishment, number of leaves per plant, general weed cover, panicle length and grain yield per hectare. Data generated were subjected to analysis of variance. Means showing a significant F-test were separated using LSD. Results obtained showed that butachlor at 1 kg ha-1 and 14 cm x 14 cm spacing gave the highest grain yield of 1441 kg ha-1 and maximum weed control. They are, therefore, recommended for adoption by farmers in Yola and similar environments.

Rice was grown in an open-field Gangetic soil condition with arsenic amended irrigation water in experimental plot at Institute of Environmental Science of Rajshahi University to see the effect of arsenic (As) on growth and yield of rice (Oryza sativa L.). A popular aman rice variety named BR-11 was cultivated with arsenic amended irrigation water (0 mg, 0.1 mg, 0.5 mg, 1.0 mg, 2.0 mg and 4.0 mg/L As containing water) in a green house made of transparent poly-ethylene paper. Sodium arsenate (Na2HAsO4) was added to irrigation water for arsenic source. The tillers number, panicle length and grain yield of BR-11 rice were found to decrease significantly (p?0.05) with increase of arsenic (As) concentration in irrigation water. The highest values of plant height and straw yield was observed in 0.5 mgL-1 treatment, whereas highest tillers number, panicles number, panicle length and grain yield were found in control treatment. The lowest values of these parameters were observed in the treatment of 4.0 mgL-1 As containing irrigation water.
