Influence of Zinc on Zinc Use Efficiency in Broccoli in Mid Hills of Himachal Pradesh

The present investigationt was carried out during rabi season of 2020-21 at the Experimental Research Farm of the Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh to find out the effect of zinc on the nutrient use efficiency in Broccoli cv. (Palam Samridhi). The experiment was carried out in a Randomized Complete Block Design (RCBD) with three replications. Manures, synthetic fertilizers and micronutrients were replicated thrice in the form of nine treatments. The observations were recorded on marketable yield per plot (kg), Zn content in soil (mg kg-1), Zn uptake in plants (kg ha-1) and zinc use efficiency (%). The treatment combination having 50% N through vermicompost + 50% N through urea + RD of PK and FYM + ZnSO4 @15 kg/ha produced best results for all the parameters studied

Influence of Modified Atmospheric Packaging on Shelf-Life and Quality of Naturally Grown Tomato (Solanum lycopersicum L.) Stored Under Different Conditions

Abstract A study was conducted to record the effect of modified atmospheric packaging (MAP), storage conditions (ambient, zero energy cool chamber and refrigerated) as well as storage period on shelf-life and quality of tomatoes produced through Subhash Palekar natural farming (SPNF) and chemical farming (CHEM) systems. Freshly harvested tomatoes (SPNF and CHEM) packed in LDPE pouches (25.40 μm and 10 pin holes/100 cm2 area) and without packaging were stored under ambient (27±2 °C and 70±2% RH), zero energy cool chamber (ZECC) (17±2 °C and 82 ±2 % RH) and low temperature conditions (10±2 ºC and 90 % RH) for shelf-life studies. The shelf-life comparison was done at every two days’ interval up to 24 days based on physiological loss in weight (PLW) and spoilage percentage. SPNF and CHEM tomatoes were compared on the basis of quality attributes (firmness, acidity, TSS, sugars, total phenols, antioxidant activity etc.), mineral content and sensory characteristics. Results revealed that tomato stored in refrigerated condition had significantly (p ˂0.05) lowest PLW and spoilage incidence and highest sensory acceptability up to 24 days and was at par with ZECC stored tomatoes. Quality evaluation indicated that tomatoes grown under SPNF system contained a higher amount of total solids, total sugars, reducing sugars, ascorbic acid, total phenols and ash. The results showed that tomatoes with MAP and stored under refrigerated storage condition retained maximum quality up to 24 days followed by tomatoes stored under ZECC (18 days) compared to 12 days at ambient conditions

Development and Standardization of an Innovative Scale for Measuring the Socio-Economic Status of Agroforestry Farmers in South Gujarat, India

Although trees in the agroforestry system play diverse roles in meeting the food, fodder, wood, and energy requirements of the agrarian community, their multifunctional contribution often remains understudied, especially while assessing the socio-economic status (SES) of farmers. Therefore, we conceptualized, developed, and standardized an instrument to appraise the SES of the farmers who practice agroforestry in semi-arid and sub-humid regions of India. We also determined the consistent performance of the scale by testing the reliability using the test–retest method. We found that the validity of the scale was accepted with a high correlation, confirming the validity and reliability of the new scale. We also prepared certain norms to identify different socioeconomic levels of agroforestry farmers. The scale used 9 major, 14 moderate, and 115 relevant minor indicators to address the dynamism of the SES and the diversification of farming systems. The proposed scale was specially designed and elastic in nature so that it has a wide scope regarding local applicability and utility, such as in multi-farming systems. Hence, this scale might be considered for measuring the SES of farmers who practice agroforestry at cross-regional and national levels

Biomass Production and Carbon Sequestration Potential of Different Agroforestry Systems in India: A Critical Review

Agroforestry systems (AFS) and practices followed in India are highly diverse due to varied climatic conditions ranging from temperate to humid tropics. The estimated area under AFS in India is 13.75 million ha with the highest concentration being in the states of Uttar Pradesh (1.86 million ha), followed by Maharashtra (1.61 million ha), Rajasthan (1.55 million ha) and Andhra Pradesh (1.17 million ha). There are many forms of agroforestry practice in India ranging from intensified simple systems of monoculture, such as block plantations and boundary planting, to far more diverse and complex systems, such as home gardens. As a result, the biomass production and carbon sequestration potential of AFS are highly variable across different agro-climatic zones of India. Studies pertaining to the assessment of biomass and carbon storage in different agroforestry systems in the Indian sub-continent are scanty and most of these studies have reported region and system specific carbon stocks. However, while biomass and carbon stock data from different AFS at national scale has been scanty hitherto, such information is essential for national accounting, reporting of C sinks and sources, as well as for realizing the benefits of carbon credit to farmers engaged in tree-based production activities. Therefore, the objective of this study was to collate and synthesize the existing information on biomass carbon and SOC stocks associated with agroforestry practices across agro-climatic zones of India. The results revealed considerable variation in biomass and carbon stocks among AFS, as well as between different agro-climatic zones. Higher total biomass (>200 Mg ha−1) was observed in the humid tropics of India which are prevalent in southern and northeastern regions, while lower total biomass (−1) was reported from Indo-Gangetic, western and central India. Total biomass carbon varied in the range of 1.84 to 131 Mg ha−1 in the agrihorticulture systems of western and central India and the coffee agroforests of southern peninsular India. Similarly, soil organic carbon (SOC) ranged between 12.26–170.43 Mg ha−1, with the highest SOC in the coffee agroforests of southern India and the lowest in the agrisilviculture systems of western India. The AFS which recorded relatively higher SOC included plantation crop-based practices of southern, eastern and northeastern India, followed by the agrihorticulture and agrisilviculture systems of the northern Himalayas. The meta-analysis indicated that the growth and nature of different agroforestry tree species is the key factor affecting the carbon storage capacity of an agroforestry system. The baseline data obtained across various regions could be useful for devising policies on carbon trading or financing for agroforestry
