Efficacy of Foliar Feeding of Ca, Zn and Cu with and without Borax on Fruit Drop and Bio-Chemical Attributes of Winter Season Guava (Psidium guajava L.) cv. L-49

The present investigation entitled “Efficacy of foliar feeding of Ca, Zn and Cu with and without Borax on Fruit drop and Bio-Chemical attributes of winter season guava (Psidium guajava L.) cv. L-49” was conducted at guava orchard of Kalyanpur nursery, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur 208002 during 2019-2020. 39 guava trees with even size and vigour were selected and were sprayed with various concentrations of different nutrients (Ca(NO3)2 @ 0.50% and 1%), (ZnSO4 @ 0.50% and 1.0%) and (CuSO4 @ 0.60% and 0.80%) with and without Borax (1%). Thirteen treatments were replicated three times as part of the RBD (Randomised Block Design) investigation. Fruits were examined in the laboratory of the Department of Fruit Science, C.S.A.U.A&T., Kanpur, for their physical and biochemical characteristics. The results of the present study revealed that fruit drop (33.94%) and bio-chemical attributes that is, Total soluble solids (13.54 0Brix), Acidity (0.46 %) and Ascorbic acid (194.30 mg/100g pulp) were improved significantly with the use of ZnSO­­­­4 1.0% + Borax 1.0% (T10).

Pineapple Cultivation in Uttar Pradesh Central Zone: Challenges and Opportunities

Pineapple cultivation in the central zone of Uttar Pradesh represents a dynamic agricultural endeavor, characterized by both challenges and opportunities. This abstract explores the unique factors that farmers face in this region, shedding light on the potential for this tropical fruit's growth and economic contribution. The central zone of Uttar Pradesh experiences a diverse climate, ranging from hot summers to cold winters. Pineapple, originally a tropical fruit, demands consistent warmth [1]. This climatic variability presents a significant challenge for pineapple growers, who must adapt their cultivation practices to ensure optimal growth and yields. Moreover, the soil quality in this region often falls short of the sandy loam and fertility requirements that pineapple plants thrive in [2]. Soil testing and enhancement become critical tasks for farmers looking to establish a suitable environment for pineapple cultivation. Pests and diseases further compound the challenges. Pineapple plants are susceptible to a range of issues, including mealybugs, aphids, and the dreaded fusarium wilt. Effective pest and disease management strategies are vital to maintaining healthy crop yields while minimizing the use of chemical pesticides [3]. Additionally, many farmers in the central zone may lack the requisite technical knowledge and skills needed for successful pineapple cultivation. Access to training and extension services, as well as modern farming practices, becomes essential to enhance agricultural techniques and overcome these challenges. On the flip side, there are significant opportunities awaiting pineapple growers in this region [4]. Pineapples are increasingly sought after for their unique flavor and nutritional value, creating a robust market demand in both local and national markets. Farmers have the potential to tap into this growing demand and enhance their income through pineapple cultivation. Furthermore, integrating pineapple cultivation into existing cropping systems offers an avenue for crop diversification, reducing dependency on a single crop and enhancing overall farm sustainability. Value addition through processing, such as converting pineapples into juice, jam, or canned fruit, allows farmers to expand their product range, increase shelf life, and reduce post-harvest losses [5]. Government support in the form of initiatives and subsidies designed to promote horticulture and agricultural diversification provides a crucial opportunity for pineapple growers to access financial and technical assistance.
