An Overview of Precision Farming

With respect to conventional farming precision agriculture increases average yields by limiting the wastage by calculating the exact required quantities of inputs. One major issue in India is the relatively small and scattered landholdings. In India 58% of the cultivable land is less than 1ha under single owner. The agricultural production system is the result of a complex interplay between seed, soil, water, and agrochemicals (including fertilizers). As a result, judicious control of all inputs is critical for the long-term viability of such a complex system. Precision agriculture is the use of technology and techniques to control the geographical and temporal variability associated with all aspects of agricultural production to improve output and environmental quality. Precision agricultural success is dependent on an accurate assessment of variability, its management, and evaluation in the space-time continuum of crop production. Precision agriculture's agronomic performance has been highly impressive in sugar beet, sugarcane, tea, and coffee crops. Due to lack of knowledge of space-time continuum the economic benefits environmental and social advantages are not explored yet. Precision agriculture is a relatively new field that integrates cutting-edge geographic technology with farming scenarios to optimize inputs, eliminate waste, and maximize returns. Precision farming systems are intended for use in many sorts of agricultural systems, ranging from row crops to dairy, and the technology has experienced extensive acceptance in the United States and across the globe.

Advancement in Tissue Culture Techniques for Fruit Crops

Tissue culture is a highly promising approach that enables the efficient propagation of many plants from tiny fragments of the parent plant within a relatively brief timeframe and confined area. Tissue culture, a contemporary approach, is primarily employed for the efficient and extensive replication of many commercially significant plant species, such as the date palm. Utilizing the tissue culture technique presents a potential approach for generating a substantial quantity of genetically homogeneous palm plants that resemble other plants and yield typical fruit within four years from initial planting. Furthermore, this technique allows to produce date palm plants devoid of diseases, exhibiting an exceptionally high survival rate of nearly 100% when compared to the traditional vegetative propagation of shoots, owing to the robustness of their root system. The process of surface sterilization holds significant importance in the production of explants for in vitro studies, as it effectively addresses the issue of bacterial and fungal contamination originating from field sources, which might vary considerably across different fruit plant species. The efficacy of tissue culture techniques for date palm acclimatization in vitro is contingent upon the observation of leaf count prior to transplantation in the greenhouse. Hence, the primary objective of this study was to investigate the determinants that govern the tissue culture of fruit trees. India is known for being the native land of various fruit crops that are both significant and minor in terms of their importance. These crops include Indian gooseberry (Emblica officinalis Gaertn.), Karonda (Carissa carandas L.), Bael (Aegle marmelos Corr.), Jamun (Syzygium cuminii L.), and jackfruit (Artocarpus heterophyllus L.), etc. These fruits possess considerable nutritional, medicinal, and therapeutic value, making them highly valuable in commercial sectors such as medicine, food, and cosmetics. The limited availability of suitable planting materials imposes constraints on the commercial production process for these crops. Using plant tissue culture techniques holds promise in substantially augmenting the number of novel cultivars or genotypes inside fruit crops. The primary aim of this review study is to consolidate and synthesize the extant body of knowledge about the tissue culture techniques employed in cultivating various fruit crops.

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.

Effect of complete and skeleton photoperiods in baya weaver, Ploceus philippinus.

A study was performed to investigate the effects of complete and skeleton photoperiods on gonadal stimulation in baya weaver, Ploceus philippinus. In August 2003, five groups of acclimatized birds (n = 7 each) were exposed to 6L: 13D: 1L: 4D, 6L: 6D: 1L: 11D, 11L: 13D and 13L: 11D. Birds were refractory and their exposure to 6L:13D:1L:4D, 6L:6D:1L:11D, 11L:13D and 13L:11D did not evoke any response. This clearly indicates that the birds were insensitive to the stimulatory effects of these photoperiods and perceived them as short days. An attempt was made to test the responsivity by subjecting all these groups to long day exposure after 16 weeks of experiment. Under 16L: 8D, birds did not show a response during the first 4 weeks of exposure (week 16 to week 20), but thereafter there was a significant photoinduction except 11L:13D (week 24), but the rate and magnitude was different. Until the end of the experiment (32 weeks), all groups of birds had maximum testicular volume except 11L:13D. Birds pre-exposed to 6L:13D:1L:4D, 6L:6D:1L:11D, 11L:13D and 13L:11D responded to 16L:8D, which suggests that these photoperiods helped the birds in recovering their photosensitivity. The results from this experiment indicate that baya weaver interprets a light period depending when the light falls relative to its endogenous circadian system.

Response to complete and skeleton photoperiods in subtropical male house sparrow, Passer domesticus (Linnaeus).

To examine the importance of the inductive light period of a skeleton photoperiod in relation to the endogenous circadian rhythm of photoinducibility mediating photoperiodic induction, P. domesticus were exposed for 28 weeks to a series of skeleton photoperiods, viz. 6L:4D:1L:13D, 6L:6D:1L:11D. 6L:8D:1L:9D and 6L:14D:1L:3D. The inductive effects of 1 hr light pulse at night varied depending on the time of its placement. To compare the inductive effects of complete and its corresponding skeleton photoperiods, birds in the second experiment were subjected for 20 weeks to 12L:12D and 6L:5D:1L:12D given daily or interposed on alternate days with constant darkness (12L:12D/DD and 6L:5D:1L:12D/DD). There was a difference in the rate and magnitude of response between the complete and skeleton photoperiods. It appears that the subtropical house sparrow uses photoperiodic strategy in regulation of its seasonal testicular responses similar to that is reported for its temperate population.
