A field experiment was conducted at the experimental site of Department Soil Science and Water Management, College Horticulture Forestry, Neri, Hamirpur (Himachal Pradesh). The consisted eleven treatments which were carried out in randomized block design with three replications. Observations for micronutrient uptake soil physical properties recorded it found that lowest bulk density achieved tr...
In order to investigate effect of application of Nitroxin and nitrogen chemical fertilizer on yield and yield components, split plot experiment on the basis of Randomized Complete Block Design with four replications was conducted. Four levels of Nitrogen fertilizer (N1: 100% chemical fertilizer, N2: 75% chemical fertilizer + 100% biological fertilizer, N3: 50% chemical fertilizer + 100% biologi...
introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

Medical plant Purslane contain large amounts of material with extraordinary health benefits of Omega-3 fatty acids and monounsaturated fatty unique combination of vitamin C, beneficial effects on the circulatory system and the heart. Therefore, research into application attract moisture substance and organic fertilizer and chemical on yield of purslane (Portulaca oleracea L.) In Ahwaz conditio...
In order to investigate the effects of municipal solid waste enriched with mineral fertilizers on some soil physical properties and lead (Pb) and chromium (Cr) concentration in plant organs of spinach, a field experiment was carried out in a factorial arrangement based on the randomized complete block design with three replications in 2008. The main plot included four levels of fertilizer, cont...
Biofertilizer is a relatively safer, environmentally friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Due to aforementioned interest, several Plant Growth-Promoting Rhizobacterial (PGPR) and rhizobial strains were i...
