Aims: To evaluate the effect of K2SO42- application on growth of soybean cultivars besides chemical parameters under salt stress. Study Design: Laid out the experiment in Complete Randomized Design in triplicates.  Analyzed the data statistically by using the statistical software Statistix 8.1. Place and Duration of Study: The study was conducted in Soil Salinity and Bio-saline Research green house and in the laboratory of Land Resources Research Institute at National Agricultural Research Centre, Islamabad (under PARC), Pakistan for three months. Methodology: To study germination parameters under salt stress, NaCl was used @ 0, 100, 120 and 140 mmol L-1. At seedling stage, interactive effect among salt stress (0 and 4.5 dSm-1), potassium sulphate (KS) application @ 10 mmol L-1 and soybean (Cvs. NIBGE-301 and NIGBE-158) was recorded for growth and ion relations.  Results: Germination, biomass, bio vigor, mass vigor and sap vigor of the seedlings and ion relations were affected highly significantly (p≤ 0.01).  Under interactive effect of KS and salt stress at vegetative stage, Na+/K+ in the plants declined with KS application. Sulphur and phosphorus concentration in the plants changed under the same conditions. Conclusion: Induced salt stress revealed germination, seed bio vigor, seeding mass vigor, and seedling sap vigor seedling and other vegetative parameters of soybean cultivars. Potassium sulphate application revealed genotypes differential response to ion relations and growth under salt stress. NIBGE-301 was more tolerant to salt stress and more responsive to potassium sulphate application than NIGBE-158.

A study based on completely randomized design with three replications was carried out at Tuber Crops Research Centre (TCRC), Bangladesh Agricultural Research Institute (BARI), Gazipur with a view to evaluating and classifying agro-morphological traits in 12 potato varieties to enumerating the genetic diversity. Discriminant function analysis (DFA) was done to determine the set of discriminatory functions contributed to separating 12 potato varieties into four distinct clusters. Discriminant function analysis showed that, function 1 explained 78.21% and function 2 explained 21.79% of total variance. The first function was more related to leaf area (having coefficient value of 0.661) and second function was more related to minituber per plant and plant height (having coefficient value of 0.644 and 0.523, respectively). Among 4 clusters, cluster II showed the highest distance (29.79) with cluster III followed by the distance between clusters III and IV (24.70) so the varieties in these clusters were genetically diverse. Based on mean value of the six quantitative characters for each of the four clusters and the inter cluster distance the cluster III and IV might be selected for future breeding program as a better parent to get positive heterosis. Cluster III contained six varieties BARI Alu 29, BARI Alu 35, BARI Alu 36, BARI Alu 37, BARI Alu 7 (Diamant), BARI Alu 8 (Cardinal) and which were characterized by lowest plant height and average values for other characters. Cluster IV contained three potato varieties BARI Alu 41, BARI Alu 46 and BARI Alu 53 which was characterized by highest plant height and second highest leaf area.

A pot experiment was conducted to investigate the effect of Zn and Fe application on growth and yield of garlic (Allium sativum L.) var. Desi Sufaid at National Agricultural Research Centre, Islamabad during Rabi season 2018-2019. Eight kilogram of sandy clay loam soil was filled in the pots. Four garlic cloves were sown in each pot. The treatments of Zn, Fe and their mixture (1:1 ratio) @ 5 kg ha-1 along with basal dose of N, P and K (100, 75 and 50 mg kg-1) fertilizer were applied at sowing following complete randomized design with three replications. The plants were allowed to stand till maturity and data on growth traits like plant height (cm), pseudo stem diameter (cm), leaf length (cm), leaves plant-1, bulb diameter (cm), cloves (bulb-1), clove weight (g) and bulb yield (g plant-1) were recorded at harvest. The mean data were analyzed statistically. The highest growth attributes like plant height, number of leaves per plant, bulb diameter, cloves, clove weight and bulb yield were harvested with micronutrients (Zn and Fe) along with basal dose of N, P and K (100, 75 and 50 mg kg-1) application which were significantly higher as compared to control. Though, all the treatments showed positive effect through growth characteristics and yield, however, the mixture of Zn and Fe application produced comparable garlic yield among all the treatments which was 6 and 4 (%) higher than that of sole application of Zn and Fe, respectively. Significant improvement in Zn and Fe concentration in garlic plant tissues was observed with the application of Zn and Fe respectively. Overall the combination of both micronutrients performed better than rest of the treatments through improved growth traits and bulb yield.

The research was performed at Botany department, Nusrat Jahan College Rabwah Pakistan to screen stress tolerance level of soil microbes (pseudomonas and penicillium) taken from NARC (National Agricultural Research Centre) Pakistan against different levels of sodium arsenite stress (1 mg/L to 10 mg/L). The research was based on completely randomized design. Three drops were applied to microbes grown on CLED (cysteine-, lactose-, and electrolyte-deficient) media to determine zone of inhibition through disk, well and spread method, while control group was without sodium arsenite application. After application of various levels of arsenic stress organisms were incubated for 24 h at 37°C. After incubation, zones of inhibition were measured. Our study has shown that both micobes cannot overcome higher levels of arsenic stress because in higher stress petriplates, increased inhibitory zones were observed.

Excessive and imbalanced use of chemical fertilizers may pose devastating effect on soil fertility and sustainable productivity. Bio-organic amendments improve soil fertility and sustainable crop productivity. Seeds of mungbean varieties i.e. NCM-2013, Chackwal-Mung 06, NM-11 and AZRI-06 were inoculated with rhizobium in saline soil. These inccilated miunngbean varieties were sown under artificially salinity developed soil (ECe= 5.0 dSm-1) using completely randomized design with three repeats for enhancement of growth. The experiment was conducted during July to September, 2015 in the Head House of Land Resources Research Institute, National Agricultural research Centre, Islamabad, Pakistan. Data were collected on germination, plant height, root length, fresh / dry weight and chlorophyll contents during experiment period. Ionic concentrations of P, Cu, Fe, Mg and Zn were determined to compare the difference of edible quality in saline soil under the inoculation of seeds with rhizobium. Effect of biozote on germination, root length, fresh weight and dry weight was significant in all mung bean varieties: NCM-2013, Chakwal Mung-06, NM-II and AZRI-06 under salt stress conditions. Maximum germination (53%) was recorded by Chakwal Mung-06 followed by 51% by AZRI-06. The maximum root length (10.1 cm) was registered by NM-II. Fresh weight / plant was maximum (5.1 g) by AZRI-06. The maximum dry weight/plant (1.5 g) was recorded by AZRI-06. Maximum P% (0.14), Cu (4.83 ppm), Fe (179.3ppm), Mg (2.07ppm) and Zn (168.8ppm) of Chakwal Mung-06 with the use of rhizobium under salt stress by NM-11. Similar trend was also recorded in ionic concentration of P, Cu, Fe and Mg by NM-11 without rhizobium under salt stress conditions.. The saline soil affected the quality of mungbean showing the reduction under salt stress without rhizobium inoculation in ionic concentration. The results of ionic values showed that NM-11 attained the highest position following the AZRI-06. [3] and[8] reported same results regarding K and P of different crops under salt stress conditions.

N Management

The proven significance of conservation agriculture (CA) in enhancing agronomic productivity and resource use efficiency across diverse agro-ecologies is often challenged by weed interference and nitrogen (N) immobilization. The collective effect of real-time N and weed management has been scarcely studied. To evaluate the appropriateness of sensor-based N management in conjunction with a broad-spectrum weed control strategy for the maize–wheat system, an experiment was conducted at ICAR—Indian Agricultural Research Institute—in New Delhi, India, during 2015–2016 and 2016–2017. Weed management in maize through Sesbania brown manure followed by post-emergence application of 2,4-D (BM + 2,4-D) in maize and tank-mix clodinafop-propargyl (60 g ha−1) and carfentrazone (20 g ha−1) (Clodi+carfentra) in wheat resulted in minimum weed infestation in both crops. It also resulted in highest maize (5.92 and 6.08 t ha−1) and wheat grain yields (4.91 and 5.4 t ha−1) during 2015–2016 and 2016–2017, respectively. Half of the N requirement, when applied as basal and the rest as guided by Optical crop sensor, resulted in saving 56 and 59 kg N ha−1 in the maize–wheat system, respectively, over 100% N application as farmers’ fertilizer practice during the two consecutive years. Interactive effect of N and weed management on economic yield of maize and wheat was also significant and maximum yield was obtained with 50% N application as basal + rest as per Optical crop sensor and weed management through BM+2,4-D in maize and Clodi+carfentra in wheat crop. The study concludes that real-time N management, complemented with appropriate weed management, improved growth, enhanced agronomic productivity and endorsed N saving under a CA-based maize–wheat system in Trans Indo-Gangetic Plains.

SUMMARYA decline in supplies of organic manures and the increased use of chemical fertilizers has led to a decrease in the micronutrient content of the soil, with attendant effects on yield.Field studies were conducted in 1986 and 1987 at the Giza Agricultural Research Centre, Egypt, to determine the effect of Cu-EDTA and Mn-EDTA foliar sprays on growth, mineral content, yield components and fibre properties of the Egyptian cotton cultivar Giza 75 (Gossypium barbadense L.).All combinations used significantly increased the uptake of Cu and Mn and the dry matter yield. The earliness of harvest and the value of yield components were all increased by the application of Cu or Mn; 25 mg/1 of both Cu and Mn gave the highest values. Lint percentage and fibre properties were not significantly affected.This study indicated that the yield of cotton, grown under otherwise standard conditions, may be increased by foliar sprays of Cu-EDTA and Mn-EDTA combined.

A field experiment was conducted at Regional Wheat Research Centre of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur for 2 consecutive years during 2006-07 and 2007-08. The objectives were to find out the optimum nutrient management practice on tuber yield, nutrient balance and economics of potato cultivation. Twelve nutrient management treatments were tested in a randomized complete block design with 3 replications. Treatments were T1=HYG (0-198-44-194-24-6-1.2), T2=MYG (0-140-34-138-18-4.5-0.9), T3=IPNS (10000-168-38-170-18-6-1.2), T4=STB (0-171-40-164-22-5-1), T5=FP (0-97-16-91-0-0-0), T6=CON (0-0-0-0-0-0-0), T7=HYG+CRI, T8=MYG+CRI, T9=IPNS+CRI, T10=STB+CRI, T11=FP+CRI, T12=CON+CRI kg ha-1 CDNPKSZnB for potato. The highest tuber yield of potato was obtained from STB+CRI (27.64 t ha-1) followed by IPNS+CRI (27.35 t ha-1), STB (27.10 t ha-1), IPNS (26.83 t ha-1), HYG+CRI (26.52 t ha-1) and HYG (26.10 t ha-1) in 2006- 07. Similar trend was found in 2007-08. The highest tuber yield and yield contributing parameters were noticed in CRI plots than without CRI. Except N, remaining nutrient balance like P K S Zn and B were found positive in case of HYG, MYG, IPNS and STB along with or without CRI nutrient managements. The balance was found almost negative in case of FP and CON. The highest BCR was observed in STB+CRI (3.96) followed by STB (3.93), IPNS+CRI (3.76), and IPNS (3.74). The higher gross return (Tk. 283331 ha-1) and also gross margin (Tk. 211761 ha-1) was observed from the same treatment. DOI: http://dx.doi.org/10.3329/bjar.v39i4.22544 Bangladesh J. Agril.

Ministry of Agriculture and Fisheries, Research Division, Ruakura Agricultural Research Centre, Hamilton, New Zealand (Received 17 April 1978) An increase in the plasma concentration of luteinizing hormone (LH) occurs in response to castration in bull calves aged 1–4 months; this response is of similar magnitude to that seen in cattle castrated as adults (Odell, Hescox & Kiddy, 1970). In bull calves castrated at birth, however, there is no increase in the plasma concentration of LH until after 28 days of age (Bass, Peterson, Payne & Jarnet, 1977). In other species a range of responses to castration has been reported. Gonadectomy of male guinea-pigs 0–35 days after birth produces an increase in the plasma concentration of LH similar to that observed in guineapigs castrated as adults (Donovan, ter Haar, Lockhart, MacKinnon, Mattock & Peddie, 1975). In contrast, the castration of young male macaques does not cause an immediate increase in the
