A Review on Crop Regulation in Guava Fruit

The influence of crop regulation on guava fruit quality (Psidium guajava) manifests in various dimensions, including physical appearance, nutritional integrity, yield, and overall productivity. This investigation explores the systematic integration of conventional and modern practices in regulating the characteristics of guava fruit. Physical appearance, including size, shape, color, and texture, is primarily influenced by targeted pruning and meticulous nutrient and water regulation. Nutritional content, encompassing essential vitamins, minerals, and antioxidants, can be enhanced and preserved through a combination of soil management, precision irrigation, and genetic engineering. Crop regulation's interplay with yield and productivity highlights the vital role of balanced pruning, efficient water and nutrient delivery systems, and modern techniques such as precision agriculture. A key finding reveals a complex challenge in maintaining a quality-quantity balance, necessitating innovation and sustainable practices for long-term benefits. This study underscores the multifaceted impacts of crop regulation on guava fruit quality and lays the groundwork for further research, emphasizing the development of integrated and sustainable strategies for optimizing both the quality and economic value of this globally significant fruit.

Soil Health and Sustainability in the Age of Organic Amendments: A Review

Organic amendments have emerged as a pivotal component in the trajectory of sustainable agriculture, given their multifaceted contributions to soil health, crop yield, and environmental conservation. This comprehensive review delves into the intricacies of organic amendments, spanning their historical context, types, sources, nutrient profiles, and their interplay with soil and plant health. Special emphasis is laid on the integration of modern technological advancements with traditional amendment practices, exploring the synergistic potential of digital agriculture and precision farming in enhancing the efficacy of organic inputs. The review also sheds light on the economic, social, and environmental ramifications, emphasizing the role of organic amendments in smallholder versus large-scale agricultural systems and their influence on farmer resilience and consumer perceptions. Crucially, this review addresses the challenges and limitations inherent in organic amendment practices, including concerns related to quality variation, scalability, over-application, and regulatory nuances. Concomitantly, the work culminates with a forward-looking perspective, highlighting emergent trends and innovations that portend the future of organic amendments in global agriculture. The findings underscore the significance of organic amendments not merely as soil additives but as integral elements in the blueprint for a sustainable, resilient, and food-secure future.

Efficacy of Nano Fertilizers on Yield, Attributes and Economics of Wheat

The present investigation was carried out to study the effect of foliar application of nano-fertilizers N and P on yield, and the economics of wheat in Semi-arid and sub-tropical region of Central Plain Zone of Uttar Pradesh. The experiment was laid out in triplicate following a randomized block design with twelve treatments comprising foliar application semi-different doses of Nano N and P. Foliar application of 1st spray of Nano N and P at 30 days after sowing (DAS) + 2nd spray of Nano N and Zn at 45 DAS along with 75% recommended dose of fertilizers (RDF) significantly (P=0.05) increased yield and have better economics. Foliar application of nano-fertilizers leads to significant improvement of crop productivity of wheat in Semi- arid and sub-tropical region of Uttar Pradesh. Moreover, the foliar application of nano-fertilizers, i.e., Nano N has direct role in increasing yield as nutrient get easily available to plant in case of foliar spray.

Evaluation of Amino Acids and Yield Components on Certain Promising Varieties of Chickpea (Cicer arietinum L.)

Chickpea (Cicer arietinum L.), often known as Bengal gram or Bengal gram, is a self-pollinated leguminous crop with diploid annual (2n = 16 chromosomes) that belongs to the family Leguminosae and sub family Papilinoceae. A lab experiment was conducted on Chickpea for biochemical and Physical characteristics on selected potential genotypes/varieties of chickpea [Cicer arietinum L.] in Completely Randomized Design (CRD) with 3 replication in pot in year of 2019-20. Seeds of chickpea genotypes/varieties were obtained from pulse Breeder, Department of Genetics and Plant breeding, CSAUAT, Kanpur. In the laboratory of CSA University's Department of Agricultural Biochemistry, Biochemical characteristics: ie. Methionine content, Tryptophan content and Physical characteristics: ie. No. of pod per plant, Yield (g/plant), Grain Yield (q/ha), Maturity period (days) were receded. Overall KGD-2021 Variety was better in terms of Biochemical as well as Physical characteristics of Chickpea followed by KGD-2012.

Influence of Organic Manuring on Sorghum: Greengram Intercropping at Different Row Ratios under Rainfed Condition

A field experiment was conducted during kharif season of 2017 at Soil Conservation and Water Management Farm of the Chandra Shekhar Azad University of Agriculture and Technology, Kanpur to find out effect of cropping systems and doses of FYM on growth, yield, water use efficiency, splash loss and economics of crops under rainfed condition. The treatments comprised of 4 cropping systems i.e. (i) sole sorghum, 45 cm apart (ii) sole greengram, 45 cm apart (iii) sorghum + greengram (2:1 ratio ) (iv) sorghum + greengram (3:1 ratio) and 3 doses of FYM i.e. (i) without FYM (ii) 10 t ha-1 (iii) 20 t ha-1 were tested in factorial randomized block design with 3 replications. Results revealed that the yield of sorghum and greengram were highest in their sole stands. The yield of sole and intercropped greengram in terms of sorghum equivalent grain yield showed significant variation, whereas sorghum + greengram (2:1 ratio) brought out significantly the highest production as compared to other cropping systems. Moreover, the land equivalent ratio, water use efficiency, gross return and net return were also found to be the highest. Simultaneously, maximum splash loss was observed under sole sorghum and minimum under greengram treatment. Increasing rates of FYM brought out significant improvement in vegetative growth, yield attributes and grain / stover yield, where a dose of 10 t FYM/ha gave best performance in respect of vegetative growth, yield attributes and grain / stover yield. In addition, net return was also noticed higher, but splash loss was lower.
