Abstract Background: A field experiment was conducted at Basonawerana district, Amhara regional state on two major soil types for three consecutive years to determine the effect of application of potassium fertilizer on yield and yield components of wheat and to verify the soil fertility and fertilizer recommendation Atlas of the study site. Six levels potassium were applied (0, 15, 30, 45, 60 and 75 kg K ha-1). At each potassium levels, a balanced nutrient of 92 kg N, 30 kg P, 30 kg S, 2 kg Zn, 0.5 kg Cu and 0.5 kg B ha-1 were applied. The experiment was laid out in a randomized complete block design with tree replications. Result: The analysis of variance showed that all the measured parameters were Significant influenced by year, soil type and the interaction of year x soil type. The highest grain yield, which was observed from cambisols during the first year was increased grain yield by 176.7 % (3954 kg ha-1) compared with the lowest yield observed from vertisols during the third year. Similar trend was also observed in straw yield and harvest index. On the other hand, all the measured parameters was non-significant influenced by K rate, interaction of K rate x soil type and year x K rate x soil types. Numerically, the highest yield (3878.9 kg ha-1) was observed from the highest K rate. However, the trend was not consistent. Conclusion: application of different rates of potassium fertilizer brings any significant growth and yield response on two soil types of the study sites. So, application of this fertilizer is not recommended for the crop with such high K soil status.

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.

SUMMARYExperiments in 1985 and 1986, at Woburn Experimental Farm in Bedfordshire, tested the effects of fungicides, applied in autumn, and a growth regulator, applied at GS3O–31 or GS32–33 in spring, on winter barley grown on two contrasting soil types in each year. Leaf diseases did not become severe in any of the experiments but take-all (Gaeumannomyces graminis var. tritici) was prevalent in 1985. Triadimenol (‘Baytan’) was more effective than flutriafol (‘Ferrax’) in decreasing the severity of takeall and its activity against the disease was related to earliness of sowing.Mean responses in grain yield to the fungicide treatments were mostly small and not significant but did not conflict with the hypothesis that crops on lighter soils benefit more from autumn fungicides than those on heavier soils. Mean effects of the growth regulator sprays were also small but they interacted with both soil type and season. Over the 2 years the later spray applied to crops on the heavier soil gave the largest mean response. Sprays applied to crops on lighter soils were often detrimental to yield, especially in 1985.

The Impact

ABSTRACT Water stress is known as the major threat to reduced growth and yield of plants in arid and semi-arid regions. Potassium is one of the indicators of plant responses to water stress. To evaluate the impact of water stress and levels of potassium on yield and yield components of two varieties of mung bean (Vigna radiata) (promising lines VC6172 and Indian), an experiment in the form of split factorial, based on randomized complete block design with three replicates was conducted in 2011, at the research farm of Safi-Abad Dezfool, Iran (latitude 32°16’ N, longitude 48°26’ E and altitude 82.9 m above sea level) .Water stress in three levels: irrigation at 120 (no stress), 180 (moderate stress) and 240 (severe stress) mm evaporation from pan, were allocated to the main plots and potassium fertilizer at three levels (0, 90, 180 kg /ha) and two varieties of mung bean (promising line VC6172 and Indian) were allotted to the sub-plots. Results showed that water stress and potassium fertilizer significantly affect all traits. The highest grain yield (2093 kg /ha) was obtained from no stress treatment in the case of 180 kg /ha potassium. Total dry matter, number of pods and grain yield, were significantly different between the two varieties. The interaction between fertilizer and variety, on dry matter and grain yield and the interaction between irrigation and variety, on dry matter were significant. We conclude that use of potassium fertilizer can reduce the adverse effects of water stress.

Insufficient stand establishment of winter wheat is a major problem in the rainfed region of the Uttarakhand hills. In order to increase germination and early establishment in the field under rainfed condition of hilly tracts this study was conducted at college of forestry VCSG University of Horticulture and Forestry, Ranichauri, Tehri Garhwal, Uttarakhand, India. The ten treatments were laid out in randomized block design with three replications in field. The treatments were VL 892 primed for 12 hrs with normal water, VL 892 primed for 24 hrs with normal water, VL 892 primed for 12 hrs with lemon water, VL 892 primed for 24 hrs with lemon water, VL 829 primed for 12 hrs with normal water, VL 829 primed for 24 hrs with normal water, VL 829 primed for 12 hrs with lemon water, VL 829 primed for 24 hrs with lemon water, VL 892 with no priming, and VL 829 with no priming. Significantly higher grain Yield of wheat was recorded in VL 829 primed with normal water for 24 hours which was statistically on par with VL 829 primed for 12 hrs with normal water, VL 892 primed for 24 hrs with normal water and VL 892 primed for 12 hrs with normal water. Significantly higher grain yield was recorded in case of priming with normal water than the priming with lime water.

High Yielding Varieties

Production and productivity of green gram is governed by environmental, genotypic trait of the crop and crop management. The more specific reason for low production and productivity of pulses is the cultivation of local old varieties under marginally fertile lands and low input management conditions. Recently, high yielding varieties of green gram have been developed and evaluation of these varieties under various management conditions will be of great importance. In this view the study was conducted to investigate the growth and yield response of different green gram varieties in Kitui and Makueni counties in Kenya. Three green gram varieties (KS20, KAT 00308 and KAT 00309) were laid out in a randomized complete block design and replicated three times. The varieties differed significantly (P≤0.05) in plant height, number of effective nodules, 100-grain mass and grain yield in both sites. Variety KS20 was the tallest in both sites in all the stages while KAT00309 was the shortest. Variety (KS20) had the highest number of effective nodules in Ithookwe (11) and Kiboko (39) with the lowest were recorded for variety KAT00308. Days to 50% flowering and maturity were different between the varieties, and KS20 had the shortest where it was recorded that the periods were shorter in Kiboko by >15 days compared to Ithookwe. In both sites, the highest grain yield was recorded for KAT00309 with 2898 kg/ha and 1568 kg/ha in Kiboko and Ithookwe, respectively. There were no signficant differences on the biological yield between the varieties but the 100-grain mass differed signficantly in both sites where variety KAT00309 was the heaviest with 7.8 g and 6.9 g in Kiboko and Ithookwe, respectively. It was concluded that variety KAT00309 could lead to the highest grain yield in both Kitui and Makueni counties under water stress conditions of the two counties.

Accurate definition of the sulfur (S) soil test–crop grain yield increase (response) relationship is required before soil S test measurements can be used to if there are likely to be responses to S fertilisers. An analysis was done using the Better Fertiliser Decision for Crops (BFDC) National Database using a web application (BFDC Interrogator) to develop calibration relationships between soil S tests (KCl-40 and MCP) using a selection of sampling depths and grain relative yields (RY). Critical soil test values (CSTV) and critical soil test ranges (CSTR) were defined at RY 90%. The ability of the KCl-40 extractable S soil test to predict grain yield response to applied S fertiliser was examined for wheat (Triticum aestivum L.) grown in Western Australia (WA), New South Wales (NSW), and Victoria and canola (Brassica napus L.) grown in WA and NSW. A smaller dataset using MCPi-extractable S was also assessed. The WA-grown wheat KCl-40 S CSTV, using sampling depth to 30 cm for soil types Chromosols (Coloured), Chromosols (Sesqui-Nodular), Kandosols (Grey and Yellow), Tenosols (Brown and Yellow), and Tenosols (Grey, Sesqui-Nodular), was 2.8 mg kg–1 with an associated CSTR 2.4–3.2 mg kg–1 and a correlation coefficient (r) 0.87. Similarly, KCl-40 S CSTV was defined using sampling depth to 10 cm for these selected soil types and for wheat grown on Vertosols in NSW. The accuracy of the KCl-40 S CSTV for canola grown in WA was improved using a sampling to a depth of 30 cm instead of 10 cm for all soil types. The canola KCl-40 S CSTV using sampling depth to 30 cm for these soil types was 7.2 mg kg–1 with an associated CSTR 6.8–7.5 and an r value 0.70. A similar KCl-40 S CSTV of 7.0 mg kg–1 was defined using a sampling depth of 10 cm, but the CSTR was higher (6.4–7.7 mg kg–1) and the r value lower (0.43). A lower KCl-40 S CSTV of 3.9 mg kg–1 or 31.0 kg ha–1 using a sampling depth of 60 cm was defined for canola grown in NSW using a limited number of S-rate calibration treatment series. Both MCPi (r = 0.32) and KCl-40 (r <0.20) soil S test–NSW canola response relationships using a 0–10 cm sampling depth were weak. The wheat KCl-40 S CSTR of 2.4–3.2 mg kg–1 can be used widely on soil types where soil sulfate is not leached during the growing season. However, both the WA canola CSTR of 6.4–7.2 mg kg–1 using a sampling depth of 30 cm and NSW canola CSTR of 25–39 kg ha–1 or 3.1–4.9 mg kg–1 using a sampling depth of 60 cm can be considered in regions outside of WA and NSW.

To evaluate the phosphorus response on winter hybrid maize, a field experiment was conducted at farm land of National Maize Research Program, Rampur, Chitwan, Nepal on 2012 and 2013. Seven levels of Phosphorus i.e. 0, 20, 40, 60, 80, 100 and 120 kg P2O5 ha-1 were applied along with 160:40 kg N:K2O ha-1. The experiment was laid out in randomized complete block design with three replications. Hybrid maize RML 32 × RML 17 was used for this study. Analysis of variance showed that plant height (cm), dry matter accumulation (g), number of kernels per row, 1000 grain weight (g) and grain yield (ton ha-1) were significantly affected with Phosphorus level. The results showed that the trend of increment was positive for grain yield with increased P level from 0 to 80 kg P2O5 ha-1. The highest grain yield (10.77 ton ha-1) was measured when 120 kg P2O5 ha-1 is applied. It is concluded that 80 kg P2O5 ha-1 can be applied in winter season for hybrid maize RML-32 × RML-17 in Chitwan valley low land irrigated condition. Further studies are necessary on different soil types, seasons, management system and varieties to get more information about the most proper addition of P on maize.

The experiment was carried out during the period from January to May, 2018 at Professor Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University to evaluate the effect of phosphorous (P) on yield and yield attributes of BRRI dhan28. The experiment was consisted of seven P doses viz. T0 = without phosphorus (P), T1 = 9 kg P ha-1, T2 = 12 kg P ha-1, T3 = 15 kg P ha-1, T4 = 18 kg P ha-1, T5 = 21 kg P ha-1 and T6 = 24 kg P ha-1 as treatments. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Only the grain yield and biological yield showed significant variations due to the effect of different rates of phosphorous. Others growth and yield attributes varied insignificantly. The result of this experiment showed that the highest grain yield (3.82 t ha-1) and biological yield (10.87 t ha-1) was obtained from 21 kg P ha-1 (T5). There was an increasing trend of grain yield with the increase of phosphorous level up to 21 kg P ha-1 and then it declined. From the result of this experiment it could be revealed that 21 kg P ha-1 gives better result regarding grain yield of HYV rice variety BRRI dhan28 at Batiaghta upazila of southwestern Bangladesh.

Allelopathic Effects

ABSTRACT Selection of tree species under agroforestry systems is crucial to sustain the productivity of a crop. In present study, allelopathic effects of the leaf litters of 5 trees named Rose wood (Dalbergia sissoo), Guava (Pisidium guajava), Eucalyptus (Eucalyptus camaldulensis), Sacred fig (Ficus religiosa) and Jaman (Syzygium cumini) species on wheat growth and yield was examined. Leaf litter of each tress species was mixed in soil with two doses @ 100 and 200 g of leaves of each species per pot. Higher shoot length, shoot dry weight, number of spikelets per spike and biological yield were recorded in 200 g sun dried Jaman (Syzygium cumini) leaves. Total number of tillers per plant and number of ears per plant were higher under the application of Eucalyptus camaldulensis leaves (200 g sun dried) as compared to other treatments. Spike length, grain yield per pot, number of grains per pot and harvest index were maximum in 200 g sun-dried Sacred fig (Ficu sreligiosa) leaves. Majority of the parameters were promoted at lower doses of leaves per pot, however, at higher doses they started inhibiting the growth and grain yield of wheat.
