Comparative analysis of various soils concerning chemical parameters in command (canal irrigated) and uncommand (well irrigated and rainfed) areas of Raisinghnagar, District Sriganganagar (Rajasthan)
Get PDFSoil is a vital source for the cultivation of all types of crops. The crop’s cultivation depends on the soil\u27s physical and chemical properties. The optimum plant growth and crop yield depend not only on the total amount of nutrients present in the soil at a particular time but also on their availability which in turn is controlled by the physical and chemical properties of soil. So, in the present study, a comparative analysis was undertaken between various soil parameters (chemical properties of soil) of different vicinity like Command (canal irrigated) and Uncommand (well irrigated and rainfed) agriculture fields of various villages in Sriganganagar District, Rajasthan. The cumulative analysis of soil chemical parameters regarding the Command (canal irrigated) area and Uncommand (well irrigated and rainfed) area were undertaken during the study period
Biology and morphometric of shoot and fruit borer (Leucinodes orbonalis Guenee) on brinjal crop under laboratory conditions
Get PDFThe study on the biology of shoot and fruit borer was carried out in the Research Laboratory of the Department of Entomology, College of Agriculture, CAU, Imphal, India, Kharif season during 2021-22. White, creamy eggs with an oval to elongated shape were placed singly in bunches. On food made from brinjal, the incubation period for the brinjal shoot and fruit borer ranged from 3-7 days, with a mean time of 4.4±1.26 days. The average larval time varied from 13-20 days with a mean duration of 16.8±2.41 days in the brinjal food portion under laboratory conditions. The larvae were white to dark pinkish throughout the instars to become fully grown. It took an average of 9-15 days for a pinkish to dark brown pupa to develop, and between 6 and 8 days for the pupa to mature into an adult. The adult moths were little with whitish wings, and they lived an average of 5.4±1.50 days for female and 2.95±0.98 for male adults, ranging from 4.0 to 5.5 days during the experiment. As a result, the entire life cycle was completed in a brinjal diet ranging from 31 to 39 days, with a mean time of 34.9±2.19 days. During the trial, the male-to-female ratio ranged from 1 to 2, with an average ratio of 1:2 in a lab setting

In the case of zinc levels, the maximum average weight of root (194.81 g), root: shoot ratio (2.62), root yield (253.30 q/ha), ascorbic acid (13.40 mg/100g), net return (Rs 167810/ha) and B: C ratio (2.96) were recorded in treatment ZnSO4 @ 25 kg/ha but these parameters were at par with Z3. However, zinc content in leaves and roots (27.31 & 47.15 ppm) were recorded more in treatment Z3 @ 30 kg/ha but these parameters did not differ significantly from treatment Z2. The combining effect of different organic manures and zinc levels was significant on the B: C ratio. Moreover, the interactive effect between vermicompost @ 3 t/ha along with ZnSO4 @ 25 kg/ha was significantly higher (3.27) over the rest of the treatments except M3Z3, M2Z3 and M3Z2, which were found statistically at par to it
Status of major wheat diseases in sub mountainous region of district Ropar, Punjab, India
Get PDFThe wheat diseases, including yellow rust, brown rust, powdery mildew and karnal bunt, continue to be the major impediments to the successful cultivation of wheat crops in the sub-mountainous region of Ropar (Punjab). During the survey, it was observed that the yellow rust disease is a pre-dominant disease of wheat in this region and has always appeared first foci of infection in Ropar district for the last several years in Punjab. The disease caused maximum infection on cultivar Barbat, HD 2967, Shriram 212 followed by WH 1105, HD 3086, PBW 677, HD 3226 and low infection on Unnat PBW 343 and PBW 1 Zn, DBW 222 and PBW 766. However, no infection was recorded in PBW 725, Unnat PBW 550 and PBW 752. The brown rust disease was absent from most of the fields. Although, occasionally found in few low-level fields (5-10S among infested fields). The head blight disease was primarily recorded in durum wheat in wet areas and the maximum incidence (16.45%) was found in the Barbet cultivar in season 2021-22. The karnal bunt disease frequently appeared in this region depending upon the weather condition at the booting stage of the crop and recorded the prevalence range of 0.1-0.40 per cent in surveyed fields. The survey reports will help to prioritize disease management in extension programmes in this region
