Background: Pulses are having a number of constraints in their production as compared to their potential in India. Green gram is an important pulse crop of the country after chickpea and pigeonpea lacks optimum fertilizer management, which leads in reduced growth and yield. The current study aimed to study the effects of different levels of potassium and zinc application on growth, yield attributes, yield and quality of green gram. Methods: The field study was conducted during Kharif 2018 at Regional Research Station, CCS HAU, Bawal on green gram cultivar MH-421. The experiment was laid out in a split-plot design with three replications and treatments comprising four levels of potassium in main plots (0, 10, 20 and 30 kg K2O ha-1) and four levels of zinc in subplots (0, 12.5, 25 and 37.5 kg ZnSO4 ha-1). Result: The results indicated that growth parameters like plant height, number of branches, number of pods, number of seeds and dry matter production were released due to the application of potassium and zinc. The number of nodules, their fresh weight and quality parameters like protein content and seed index significantly increased with the application of potassium up to 20 kg K2O ha-1, but non-significant increment with zinc application. Seed and straw yield increased significantly with potassium and zinc application up to the levels of 20 kg K2O ha-1 and 25 kg ZnSO4 ha-1, respectively. Higher net monetary returns of Rs. 31528 ha-1 with B:C ratio (1.61) was recorded under the treatment combination K20Zn25 (20 kg K2O ha-1 along with 25 kg ZnSO4 ha-1). It was concluded that higher green gram yield with better quality and more net return was achieved when potassium and zinc were applied @ 20 kg K2O ha-1 and 25 kg ZnSO4 ha-1, respectively.

Various methodologies (soil or foliar application) and doses of zinc (Zn), iron (Fe) and manganese (Mn) either in conjunction with urea or in combination with one another were used to evaluate grain and straw production as well as nutrient concentration and their uptake in wheat. The experiment's findings showed that adding Zn, Fe and Mn significantly enhanced grain and straw production over control as well as available nitrogen (N), phosphorus (P) and potassium (K) content and their uptake. When 2.5 mg Zn kg-1 + 5 mg Fe kg-1 + 5 mg Mn kg-1 + 30 mg N kg-1 was applied, the maximum grain yield, straw yield, P uptake in grain and straw, as well as K concentration and uptake in grain and straw were found. Highest N content both in grain and straw was observed when 0.5% FeSO4 + 3 % Urea were applied. Phosphorus content in grain was recorded highest when 0.5% MnSO4 + 0.5% Citric acid was applied whereas in straw maximum concentration of phosphorus was noticed when 0.5% ZnSO4 + 2% Urea were applied. Highest uptake of nitrogen in grain was found when 0.5% MnSO4 + 2.5% Urea were applied and in straw when 0.5% FeSO4 + 3 % Urea were applied. The experimental results also showed that micronutrient (Zn, Fe and Mn) concentration and uptake significantly increased as compared to control with micronutrient application (Zn, Fe and Mn).

Eight representative pedons of sugarcane growing soil of Haryana viz., Damla, Yamunanagar (P1), Shahabaad, Kurukshetra (P2), RRS, Karnal (P3), Kaithal (P4), Mehlana, Sonipat (P5), Nidhani, Jind (P6), Mokhra, Rohtak (P7) and Meham, Rohtak (P8) were studied for morphological, physico-chemical characteristics and classified as per Soil Taxonomy. The colour of the studied pedons varied from yellowish brown (10YR 3/2) to dark brown (10YR 5/5) in colour, with dominant hue of 10YR. The range of bulk density of different horizons was 1.05 to 1.33 Mg m-3. These soils were slightly alkaline to moderately alkaline in reaction. The soils of all the pedons of studied area were non saline in nature having EC < 1.36 dSm-1. Exchangeable Sodium percentage (ESP) and Base Saturation Percentage (BSP) ranged from 1.65 to 47.55 % and 23.18 to 99.60 % respectively. The CEC of the soils ranged from 1.98 to 13.82 cmol (p+) kg-1. The soils of the area were classified according to Soil Taxonomy as  Fine loamy, Mixed, Hyperthermic, Typic Ustocrepts (Pedon 3,6 and 7), Fine loamy, Calcareous, Mixed, Hyperthermic, Typic Haplustepts (pedon-4), Fine loamy, Mixed, Hyperthermic, Typic Haplustepts (pedon-2), Coarse loamy, Mixed, Hyperthermic, Aquic Ustochrepts (pedon-5) and Coarse loamy, Mixed, Hyperthermic, Typic Haplustepts (1 and 8).

Micronutrient insufficiency in plants is becoming increasingly common, particularly in cereals crops around the world. These deficits result in a loss of yield as well as deterioration in the nutritional quality of the crops. The experiment was carried out in screen house for Rabi season of 2017-18, Soil Science Department, CCS HAU, Hisar to measure the impact of methods and dosages of zinc (Zn), iron (Fe) and manganese (Mn) application on post-harvest soil characteristics and wheat quality. The findings of this research illustrated that DTPA-extractable Zn and Mn increased significantly with the addition of Zn and Mn, respectively as compared to control. With the application of micronutrients, the sedimentation value and protein content of wheat both significantly increased in comparison to the control. Maximum increase in sedimentation value (54.0) was found when 0.5 % ZnSO4 + 2.5 % urea was applied. Whereas, maximum increase in protein content (12.2%) was observed when 0.5 % FeSO4 + 3 % urea was applied. Overall, quality of wheat improved with the application of micronutrients but there was no significant effect of these applications on soil parameters. There was no significant variation in soil pH, soil organic carbon (SOC), electrical conductivity (EC), available nitrogen (N), phosphorus (P), potassium (K) and DTPA-extractable Fe when micronutrients were applied as foliar or basal doses.
