The study was conducted in two natural oak forest of Nainital (Uttarakhand) India, during 2012-2013 to determine the weight loss pattern in leaf litter of two Central Himalayan Oaks (i.e., Quercus leucotrichophora A. Camus. and Quercus floribunda Lindl.) with the help of litter bag technique. The present study concluded that weight loss proceeded throughout the study period and relatively higher within 60 days after the placement of litter bags into the soil. Among these two species, higher weight loss observed in Q. floribunda as compared to Q. leucotrichophora across both the sites. Within 365 days, average weight loss observed about 60% in Q. leucotrichophora and 62% in Q. floribunda. Decay rate coefficient rate ranged from 0.0596- 0.0014 for Q. leucotrichophora while it varies from 0.0558 to 0.0013 for Q. floribunda. The monthly relative decomposition rate (RDR) ranged between 0.0598-0.0014 g/g/day and 0.0208-0.0050 g/g/day for Q. leucotrichophora and Q. floribunda, respectively. Climatic factors (rainfall, temperature and relative humidity) also influenced the rate of decomposition.

Anatomical Parameters

The physiological and anatomical impact of field dodder (Cuscuta campestris Yunck.) on alfalfa and sugar beet was examined under controlled conditions. The following parameters were checked: physiological — content of pigments (chlorophyll a, chlorophyll b, and carotenoids) and mineral nutrients: nitrogen, phosphorus, potassium, and percent of organic and mineral nutrients; and anatomical — thickness of the epidermis and cortex, diameter of the stem and central cylinder of alfalfa plants, diameter of tracheids and phloem cells, area of xylem and phloem, and hydraulic conductance of petiole bundles in petiole vascular bundles of sugar beet plants. Leaf parameters were also measured on both host plants: thickness of upper and underside leaf epidermis, thickness of palisade, spongy and mesophyll tissue, and diameter of vascular bundle cells. Pigments content and anatomical parameters were measured 7, 14, 21, 28, 35, and 42 d after infestation (DAI), while mineral nutrient contents were determined 20 and 40 DAI. Field dodder caused a significant reduction in pigments content in infested alfalfa (15%–68%) and sugar beet plants (1%–54%). The results obtained in this study confirmed that this parasitic flowering plant has a strong effect on most anatomical parameters of the stem and leaf of alfalfa and leaf and petiole of sugar beet. Also, it was revealed that field dodder increased the contents of N, P2O5, K2O, and organic nutrients in infested alfalfa plants, while infested sugar beet plants had higher contents of N and organic nutrients compared with non-infested plants.

Background: Nutritional security overrides food security and the present day agriculture focusses more on sustainable and regenerative agriculture in which use of organic inputs assumes prime significance. The search for viable alternatives to the chemical sources of nutrients demands production of the organic nutrient inputs in large quantities. Organic nutrition is expensive on account of the low nutrient contents and large quantum needed and hence unless produced in situ, turn out to be highly expensive. Organic wastes in the form of crop residues are available in plenty in agricultural fields. Tree leaf litter is another biowaste considered as menace under off farm situations. Rapid resource recycling techniques offer immense potential for the safe disposal of the litter and conversion to quality manures. In this background an experiment was conducted to assess the efficacy of litter composts as nitrogen sources in vegetable cow pea (Vigna unguiculata subsp. unguiculata) in terms of the agronomic efficiencies and nutrient uptake. Methods: The field experiment was conducted in College of Agriculture, Vellayani, Thiruvananthapuram, Kerala Agricultural University during December 2018 to March 2019 in randomized block design with three replications. The treatments included the compost of the two tree species litter prepared by composting with different decomposer organisms and additives and enriched with the biofertilizer, PGPR Mix I. Result: The results of the experiment revealed the highest vegetable yields (7.80 t ha-1) in the treatment involving mango leaf litter composted with glyricidia leaves and earthworms on par with Kerala Agricultural University package of practices recommendation for cowpea and it was 2.7 times that in absolute control. The total nutrient uptake was the highest with mango litter co-composted with poultry manure as nutrient input. Agronomy efficiency indices, in terms of nitrogen were significantly superior for the treatments including mango litter composts and hence prove a suitable nutrient input in vegetable cowpea cultivation.

A pot experiment was conducted at the open net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh, during the period from March to June 2007 using soil collected from the surrounding areas of Gazni sal forest of Jhenaigati upazilla under Sherpur district to study the effect of different forest tree leaf litters on growth, yield, nutrient contents of red amaranth cv. Altapety. Plant height, number of leaves plant-1, dry weight plant-1 and moisture content (%) were significantly influenced by the addition of different forest tree leaf litters and highest values were obtained from the chemical fertilizer treatment which was identical with teak leaf litter in most of the parameters. The lowest values of most of the parameters were obtained from control treatment. Nutrient contents of red amaranth were significantly influenced by the addition of different leaf litters except Mg. The highest and lowest values of most of the nutrient contents and their uptake were recorded from chemical fertilizer and control treatment, respectively. It was also observed that addition of different leaf litters substantially decreased soil acidity and significantly increased the organic matter, total N, available P, exchangeable K, available Ca, Mg contents in the post harvest soil. The performance of these leaf litters with respect to growth, yield, nutrient contents and their uptake by red amaranth and the soil fertility was in the order teak >eucalyptus>acacia>sal. Overall results suggested that leaf litters can be used as an alternative of chemical fertilizer in the surrounding areas of Gazni sal forest for profitable production of leafy vegetables like red amaranth.
