Physiological attributes of tomato (Lycopersicon esculentum Mill.) influenced by different sources of nutrients at foothill of eastern Himalayan region

Abstract

The present investigation was aimed to assess the influence of different organic manures (Farmyard manure and vermicompost), inorganic fertilizers and Azophos biofertilizer on different physiological attributes of tomato. The field experiment was conducted during 2005-06 and 2006-07 at Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India by combining 14 treatments in randomized block design with 3 replications. The results revealed that nutrient sources significantly influenced different physiological attributes as the chlorophyll content of leaves and LAI (Leaf area index) kept on increasing and peaked at 60 DAT(Days after transplanting) and 75 DAT respectively and declined thereafter. The dry matter production was highest at 75 DAT. Again application of vermicompost (4 t/ha) with 75% of inorganic fertilizers inoculated with biofertilizer resulted in significant improvement of physiological attributes as well as yield. Vermicompost emerged as better organic nutrient source over farmyard manure. Inoculation with biofertilizer exerted more positive results over uninoculated treatments and benefits of biofertilizer application were more in presence of vermicompost as compared to farmyard manure.

A Study of the Efficacy of Various Nutrient Sources on the Growth and Yield of Cabbage

“…The increase in yield might be due to better root development, nutrient and soil water consumption, higher leaves number and larger surface area for photosynthesis and increased food accumulation, uptake of nutrients and water from the soil, a higher number of leaves and a greater surface area for photosynthesis as well as enhanced food accumulation. Head size is directly influenced by the availability of major nutrients to the plant and for satisfactory yield, there must be adequate levels of plant nutrients (Chatterjee, 2010).…”

The integrated use of excreta-based vermicompost and inorganic NP fertilizer on tomato (Solanum lycopersicum L.) fruit yield, quality and soil fertility

“…An interesting result was that, even though statistically they were the same (P [ 0.05), the values for fruit size and weight of the integrated treatments (T3, T4, T5 and T6) were found to surpass the sole treatments (T7 and T8). The increased fruit size under integrated use of vermicompost and inorganic fertilizer may be due to large and balanced uptake of nutrients and effective utilization of these nutrients for increased synthesis of photo-assimilate (carbohydrates) which would later be partitioned and remobilized from the source to sink (from leaf towards developing fruits) (Chatterjee 2013).…”

Genetic analysis of agronomic and biochemical variables among different tomato (Solanum lycopersicum L.) accessions

“…Recently, the validity of these types of association studies for lowering cancer risks has been questioned (Boffetta et al, 2010), but the evidence supporting the health benefits of tomato consumption remains strong (Willett, 2010). Tomatoes are consumed in many ways, the fresh fruits are eaten in salads, sandwiches and as salsa and the processed varieties are consumed dried or as pastes, preserves, sauces, soups and juices (Chatterjee, 2013). Dishes featuring tomatoes are both traditional and interwoven into the culture of many countries and there are many types of tomatoes with diverse uses which explain its global appeal (Beckles, 2012).…”
