Abstract

In this article, we consider a K − algebra R with a partial action α of a finite group G on it. If each g D_g is generated by a central idempotent of R, we answer the question: If P₁ ⊂ P₂ are primes in R and P₂ minimal over P₂∩ Rα, does some prime P₁ exist in Rα such that P₁ is minimal over P₂∩ Rα, and P1⊂p2? Similar results are proved by interchanging R and Rα.

Abstract

The study of 'Chail Series', 'Jaunsar Series' and 'Simla Slates' in the Simla Himalaya has brought out the incongruities in the present lithostratigraphy of these formations. The Simla group, divisible into four formations, is the revised classification proposed. The Basantpur, with shale, siltstone and abundant limestone interbeds, is at the bottom of the Simla group sequence, and in the ascending order, succeeded by the Kunihar with shale and stromatolitic limestone, the Chhaosa containing flysch sediments and the Sanjauli with conglomerate and grit facies. The Simla group represents a typical geosynclinal cycle of sedimentation deposited over the Shali, Sundernagar and Mandi-Darla volcanic rocks.

Abstract

In 2007, with the help of DBT, a research project to create mutant resources for functional genomics in rice was launched through a national initiative involving ICAR-National Research Centre on Plant Biotechnology, New Delhi; ICAR-Indian Agricultural Research Institute, New Delhi; Tamil Nadu Agricultural University, Coimbatore; ICAR-Indian Institute of Rice Research, Hyderabad; University of Agricultural Sciences, Bangalore and Punjab Agricultural University, Ludhiana. Genetically well-defined material is a prerequisite for functional genomics. Thus, the project aimed to generate EMS mutants in the background of an upland and short duration aus genotype, Nagina22, characterize the mutants and use them in crop improvement. As of now, nearly 85,000 rice M2 mutant populations have been created under the project. Based on field phenotyping, gain and or loss of function mutants for tolerance to herbicide spray, drought, salinity and resistance to rice leaf and panicle blast, sheath blight and high phosphorus (P) use efficiency under low P field have been identified. Notably, the herbicide-tolerant mutant identified is under the process of registration for distribution to public and private rice breeders under appropriate material transfer agreement. Besides this, the project also aims to serve as a 'National Repository of rice EMS mutant resource' for the researchers involved in rice biology and improvement in the country.

Abstract

The effect of continuous application of fertilizers and amendments on wheat yield and DTPA extractable micronutrients in an acid Alfisol during rabi (2016-17) was evaluated in field experiment at the research farm of the Department of Soil Science, CSKHPKV Palampur. This experiment was initiated during 1972 in randomized block design with eleven treatments which were replicated three times. The soil of the experimental area was silt loam and classified taxonomically as "Typic Hapludalf". The highest productivity of wheat was recorded in the treatment comprising 100 per cent NPK + FYM and was statistically comparable with 100 per cent NPK + lime. Continuous application of N alone resulted in zero yield and omission of K and S from the fertilization schedule also resulted in drastic reduction in the yield. In surface soil (0-0.15m), application of Zn along with 100 per cent NPK (T₅ ) recorded the highest value (3.75 mg kg^-1) of DTPA extractable Zn and combined use of FYM with optimal dose of NPK (T₈ ) recorded the highest value of DTPA extractable Fe, Cu and Mn (38.0, 2.25 and 37.25 mg kg^-1, respectively). The lowest value (1.08, 18.8, 1.32 and 17.90 mg kg^-1) of DTPA extractable Zn, Fe, Cu and Mn, respectively, was recorded in control plot.

Abstract

This study was undertaken in an on-going long-term fertilizer experiment, initiated during 1972-73 at Experimental Farm of Department of Soil Science, CSK HPKV Palampur to work out the relationship of soil health parameters with quality of maize in an acid Alfisol. The soil of the experimental site was silt loam and classified taxonomically as Typic Hapludalf. The experiment consisted of eleven treatments with varying levels of NPK fertilizers, and FYM & lime as amendments. Continuous application of fertilizers and amendments for forty-six years significantly influenced the yield of maize. The highest grain (46.5 q ha^-1) and stover yield of maize (77.0 q ha^-1) was recorded in the 100 per cent NPK + FYM treatment and was at par with 100 per cent NPK + lime. Continuous omission of S and K decreased the grain yield by 55 and 53 per cent, respectively, whereas regular application of N alone resulted in zero yield. Soil health parameters and grain quality traits were assessed and the relationship between soil health parameters and quality traits of maize grains was worked out. Correlation studies revealed that soil organic carbon exhibited a positive and significant relationship with non- reducing sugar (r = 0.737**). Similar positive relationship was found between porosity and non-reducing sugars (r =0.940**). There was a positive and significant relationship between dehydrogenase activity and reducing sugars (r = 0.866**). Invariably, bulk density exhibited negative and significant relationship with different quality traits of maize grains.

Abstract

Field experiments were conducted at Organic Farm Holta of Department of Organic Agriculture and Natural Farming, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur during kharif and rabi seasons of 2018-19 and 2019-20 on silty clay loam soil to study the performance of different quality traits under different farming practices in legume-based cropping systems. The experiment was laid out under Split Plot Design with three replications comprising of three sequences in legume – vegetable based cropping system i.e., “soybean – onion”, “okra – peas” and “mash – garlic” under different farming practices i.e., Organic farming, Natural farming, Inorganic and Integrated farming practices.Comparing different farming practices, highest protein content (39.1%) was observed in crops under organic farming practices followed by zero budget natural farming practices (38.3%). Significantly higher protein yield of these crops was also recorded under organic farming practices (449 kg/ha) followed by integrated farming practices (405 kg/ha).Carbohydrate yield (1127 kg/ha) and fat yield (120 kg/ha) of crops were significantly highest in integrated farming practices and inorganic farming practices respectively. “Soybean-onion” cropping system produced significantly highest protein yield (644 kg/ha) and fat yield (300.7 kg/ha) as compared to other cropping systems. However, higher protein content and low carbohydrate and fat were recorded in this system when grown under organic farming practices and was found to be the best amongst all cropping systems and farming practices combinations.
