AbstractNutrient management is a key component of best agronomic practices for optimal crop production. The continuous use of high yielding genotypes and exhaustive cropping systems has resulted in potassium deficiency. Furthermore, the imbalanced use of nutrients, particularly potassium (K), has resulted in persistent depletion from agricultural soils. To address this issue, a field experiment was conducted to determine the influence of different potassium levels under a split application on yield and yield attributes of wheat crops. The experiment was laid out in a randomized complete block design replicated four times. Five K levels (0, 60, 80, 100 and 120 kg ha−1) and different K application timings (whole dose (Basal) at sowing, equal doses at sowing+ 30 DAS, half dose at sowing+ equal doses at 30 +60 DAS and equal doses at sowing+30+60+ 90 DAS). The findings of the study revealed that potassium levels and their application times substantially influenced yield and yield components of wheat. The application of K at 120 kg ha−1 delayed anthesis and maturity and enhanced chlorophyll content (53), tillers m−2 (293.4 m−2) and increased plant height (97.1cm). The application of K 80 kg ha−1 significantly increased grain protein, nitrogen, phosphorus and potassium content which resulted in a higher (4227 kg ha−1) grain yield. In the case of K timings application, the higher grain yield (3758 kg ha−1) was achieved when K was applied one time at sowing time. It is concluded that K at the rate of 80 kg ha−1 should be applied in full at sowing for achieving higher wheat production.

Productivity Improvement

Vertisols are important agricultural soils in the Ethiopian highlands. The highland part of the Jama district is one of which Vertisols have huge coverage and are underutilized due to waterlogging. Such potential Vertisol areas need to be put under wise cultivation. Thus, a study was conducted to investigate the effects of soil drainage methods on surface runoff, soil loss, and yield of wheat crop as indicators of productivity improvement of typical Vertisol in the Jama district of Amhara Region, Ethiopia, during the rainy season of 2017/18. The treatment comprised three soil drainage methods (BBF120, BBF80, and BBF40) arranged in a randomized complete block design with three replications on standard runoff plots. Statistical Analysis System, version 9.0, was used to perform analysis of variance and mean separation of the collected data on yield, soil loss, and runoff. The result indicated that the effect of BBF120 brought significantly ( P < 0.05 ) higher difference on surface runoff, yield, and biomass of wheat over BBF40. The rainfall of about 55.05%, 51.45%, and 48.07% was lost as runoff from BBF120, BBF80, and BBF40, respectively. Drainage method BBF120 gave 34.6% and 17.3% of grain yield advantage over the drainage methods of BBF40 and BBF80, respectively, whereas soil loss was not significantly ( P > 0.05 ) different among all treatments; it is still in the range of soil loss tolerance in Ethiopia. As enhanced drainage is a requirement for successful crop production on Vertisol areas, BBF120 is recommended for draining excess runoff and consequently maximizing the yield of wheat in the study area and others with a similar farming system and agroecology.

Vertisols are suited to dry-land crop production in semi-arid environments since the residual moisture in the soil can support crop growth after the end of the rainy season. However, traditional cropping systems seldom utilize residual moisture of Vertisols for crop production. Farmers need suitable crop species to sustain and enhance their production under such soil and climatic conditions. Chickpea is the strategic crop well adapted to Vertisols and derives most of its water requirements from the residual soil moisture. Yet, different chickpea varieties found to adapt and produce different yields at different locations. The experiments were conducted for two consecutive years (2016 and 2017) on farmers training centers in two districts of Southern Ethiopia. Six released varieties; Arerti, Habru, Yelibe, Naatolii, Fetenech, Kutaye and a Local check were used for the experiment. The trials were laid in a randomized complete block design with four replicates. Data were collected on phenological traits, growth and yield attributes, and grain yield. The results showed that there was significant variation among the tested chickpea varieties in all the agronomic traits recorded. Varieties Arerti and Habru revealed superiority in grain yield, pod setting, hundred seed weight and biomass over the Local check across locations. Based on yielding performance and farmers’ preference, varieties Arerti and Habru are recommended for production in the selected districts and similar agro-ecologies in southern Ethiopia.

Field experiment was conducted during Rabi seasons of 2010-11, 2011-12 and 2012-13 at Research and Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur to examine and study the phenology, accumulation of growing degree days (GDD), heliothermal units (HTU), photothermal unit (PTU) and performance of wheat (Triticum aestivam L.) of four wheat varieties grown under five different sowing dates in factorial Randomized Block Design. It was observed that GDDs got reduced significantly with subsequent delay in sowing time. For our study purpose and as per package of practices, 25 November D1 can be taken as early sowing and D2 - 5 December as timely sowing conditions.  The wheat varieties Amar and Sujata took highest GDD, HTU and PTU to maturity.  On the mean basis the variety Kanchan produced highest grain yield (3147 kg/ha) followed by GW-273 (2947 kg/ha).  The significant reduction in grain yield was recorded when sowing was delayed beyond D2 - December 05.  Among the wheat varieties Kanchan showed better performance in terms of RUE followed by GW-273 and Sujata. Highest HUE was observed in wheat variety Kanchan followed by Sujata and GW-273. Varieties giving higher yield, RUE and HUE are identified under varying growing environments so as to suggest the appropriate sowing dates of wheat varieties in Chhattisgarh plains. GDD is giving consistent results as its variability is least varying between 3.4-5.3 per cent for different varieties and therefore it is reliable index for studying environmental effects on wheat in this region. Lowest RUE was observed under 5 January sowing (D5) in the all varieties which leads to conclusion that this sowing date must be avoided and wheat crop sowing must be completed latest by 25 December to avoid adverse effects on productivity.

Field trials were conducted in savanna ecologies of Nigeria during the 2015 and 2016 seasons using maize (PVA8) and soybean (TGX 1448-2E) intercropping systems with different fertilizer rates to evaluate the yield of maize and assess the best intercropping system for resource management. Single plant stands and two plants/stand and 2 arrangements of rows (one row on a ridge and two rows on a ridge) were used to impose maize plant densities evaluated in strip inter-crop with soybean. The trial was factorial, laid out in a randomized complete block design and replicated three times. Thus, 8 maize-soybean strip cropping systems and application of 3 NPK rates were evaluated at Saki-Oyo, Ilorin, and Nasarawa (southern Guinea savanna), Kaduna in the northern Guinea savanna, Funtua (Katsina) and Gusau (Zamfara) located within Sudan savanna ecologies of Nigeria. Data on yields and yield components were collected. The intercropping systems were assessed using existing intercropping indices such as Land Equivalent Ratio (LER), Relative Crowding Coefficient (K), Aggressivity (A), Competitive Ratio (CR), Actual Yield Loss (AYL), Intercropping Advantage (IA) and Monetary Advantage Index (MAI). The result showed that Nasarawa and Kaduna were most ideal locations for maize production in the Nigeria savannas. The highest grain yield of 4.04 tons/ha maize and 1.36 tons/ha soybean were obtained from seeding 1 plant/stand in 2-rows per ridge x 4 ridges of maize alternated with 2 rows of soybean with the application of NPK at 100:50:50. The LER was 1.11, AYL (1.10) and MAI (208) gave a profit of ₦312,102.00 (US$990.80) ha-1 with a benefit-cost ratio of 2.38 and production efficiency of 29.56%. The study concluded that, seeding 80% maize and 20% soybean per ha will lead to sustainable maize crop production with limited use of fertilizer. It can be adopted by the farmers in Nigeria savannas as a relatively profitable intercropping system.

A field experiment was conducted on sandy loam soil at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, Uttar Pradesh during rabi season (December 2018 to April 2019) in randomised block design with three replications. The treatments comprised of twelve tillage crop establishment methods were used for the experimentation and different observations were recorded during the crop growth period. The results indicated that the growth characters of wheat were significantly higher under wide raised bed residue retention (T9) except narrow raised bed residue retention (T7) and conventional tillage residue incorporation (T11) compared to other treatments. The grain yield, biological yield, harvest Index, yield attributes and grain weight were higher in treatments T9, T7, and T11, respectively. The improvement in grain yield with the tune of 32.09%, 28.14% and 25.49% was under treatments T9, T7 and T11 as compared to T12. It can be concluded that among crop establishment methods, wide raised bed residue retention (T9) found excellent to increase growth, yield attributes and yield for sustainability of wheat crop.

AbstractOrganic farming systems use green and animal manures to supply nitrogen (N) to their fields for crop production. The objective of this study was to evaluate the effect of green manure and composted cattle manure on the subsequent winter wheat (Triticum aestivumL.) crop in a semiarid environment. Dry pea (Pisum sativumL.) was seeded in early April and terminated at first flower in late June. Composted cattle manure was applied at 0, 11.2 or 22.5 Mg ha−1just prior to pea termination. Winter wheat was planted in mid September following the green manure or tilled summer fallow. No positive wheat response to green manure or composted cattle manure was observed in any of the 3 years of the study. In 2 of the 3 years, wheat yields and grain test weight were reduced following green manure. Green manure reduced grain yields compared with summer fallow by 220 and 1190 kg ha−1in 2009 and 2010, respectively. This may partially be explained by 40 and 47 mm less soil water at wheat planting following peas compared with tilled summer fallow in 2008 and 2009, respectively. Also, in 2008 and 2009, soil nitrate level averaged 45 kg ha−1higher for black fallow compared with green manure fallow when no compost was added. Organic growers in the semiarid Central Great Plains will be challenged to supply N fertility to their winter wheat crop in a rapid and consistent manner as a result of the inherently variable precipitation. Growers may need to allow several years to pass before seeing the benefits of fertility practices in their winter wheat cropping systems.

Raw Wastewater

Due to increasing scarcity of fresh water, use of unconventional water source (e.g., wastewater) in irrigation has now become important. However, inclusive information on the effects of wastewater on crop production and soil health is necessary for such intervention. This study was designed to evaluate these effects by demonstrating the contribution of municipal wastewater (hereafter called wastewater) on yield and nutrient requirement of wheat (<i>Triticum aestivum</i> L.) cv Shatabdi. Five irrigation treatments - I1, I2, I3, I4 and I5  were tested in a Randomized Complete Block Design (RCBD) with three replications during November-March of 2007-2008, 2008-2009, 2009-2010 at the experimental field of the Bangladesh Agricultural University,  Mymensingh. The treatments I2-I5 consisted of blended wastewater and I1 of fresh water (control). The ratio of wastewater to total irrigation water was 0.25, 0.50, 0.75 and 1.0 in I2, I3, I4 and I5, respectively. Wheat was cultivated with three irrigations and recommended doses of fertilizer in three consecutive years. Wastewater contained nitrogen (N), phosphorus (P) and potassium (K) @ 17.5, 3.7 and 10.3 mg/L, respectively, and irrigation by raw wastewater (I5) contributed 19.1, 15.1 and 21.7% of the recommended N, P and K, respectively. Biomass yield increased with increasing fraction of wastewater in irrigation. Grain yield increased for the wastewater fraction of 0.50 - 0.75 in irrigation but decreased when irrigation was applied by raw wastewater. Excess fertilizer (under I5) boosted up growth of wheat, but did not contribute to the grain yield. Number of grains per spike; and grain, straw and biological yields significantly (p = 0.05) increased due to the contribution of wastewater. Wastewater significantly improved grain and biomass production, with the largest value obtained in I4 (4.61 t/ha grain yield and 11.36 t/ha biomass yield).  Raw wastewater in combination with recommended fertilizer doses caused over-fertilization that contributed only in biomass production but not in grain production of wheat and irrigation by wastewater substantially reduced fertilizer requirement of wheat.The Agriculturists 2016; 14(1) 01-14

A field experiment was conducted during  autumn season 2018 at Al Salam district, Maysan governorate. The aim was to evaluate some growth properties and grain yield of  three varieties of cowpea, Vigna sinensis L. (Local, Patton Boa and Atta E) grown under different levels of potassium sulphate  (0, 43, 86 and 129 kg h-1). The  experimental  design was applied according to the random complete block design in a split arrangement (Split Plots in RCBD). In on hand, the results showed a significant differences between the varieties. The local variety significantly gave highest plant length , leaf area, pods number, seeds number pod-1 and grain yield and which were 60.75cm, 2936.81cm2, 39.60 pod. plant-1, 7.69 seed pod-1, 99.93 g and 4.16 t. h-1 respectively. While the varieties Baton Boa gave highest weight of 100 seeds and gave 37.58 g. In other hand, as compare to the control, the addition of potassium up to 129 kg. h-1 lead to significant increase in plant length, leaf area, pods plant-1, seeds number pod-1 and grain yield plant-1 and total grain yield which were 53.33 cm, 3455.91 cm2, 51.61 pod. plant-1, 8.76 seed. pod-1, 125.93 g. and 5.25 T.h-1 respectively. Whereas, the control treatment (K0) gave the highest weight of 100 seeds (45.11 g). The Interaction between varieties and potassium  had a significant effect on almost  growth and yield characteristics.

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during winter (Rabi) season of 2013-14 to evaluate the effect of integrated use of organic and inorganic fertilizers on the growth, yield and nitrogen (N) uptake of wheat. There were six treatments such as T0 (control), T1 [STB-CF (HYG)], T2 [STB-CF (HYG) + CD (5 t/ha)], T3 [STB-CF (HYG) +PM (3 t/ha)], T4 [STB-CF (HYG) COM (5 t/ha)] and T5 [FP (Farmers’ practice)]. The experiment was laid out in a Randomized Complete Block Design with four replications. Soil test based nitrogen, phosphorus, potassium, sulphur, zinc and boron were used @ 100, 20, 60, 10, 3 and 2 kg ha-1, respectively. The integrated use of organic and inorganic fertilizers significantly increased the yield attributes as well as grain and straw yields of wheat. The treatment T3 [STB-CF (HYG) + PM (3 tha-1)] produced the highest grain yield of 3554 kg ha-1 (69.67% increase over control) and straw yield of 3635 kg ha-1 (62.83% increase over control). The lowest grain yield (2094 kg ha-1) and straw yield (2232 kg ha-1) were found in control treatment. The N content and uptake by wheat were also markedly influenced by combined use of organic and inorganic fertilizers and the treatment T3 demonstrated superior performance to other treatments. So, the applications of fertilizers in combination with poultry manure @ 3 t ha-1 can be used for the successful cultivation of wheat in Old Brahmaputra Floodplain soil. Progressive Agriculture 27 (2): 149-153, 2016
