Impact of biofertilisers and agrometeorological conditions on phenological growth of pepper (Capsicum annuum L.) in organic agriculture

Abstract

The pepper has a relatively large share in the general structure of the vegetable production in Bulgaria. The objective of this research was to investigate the influence of biofertiliser Emosan (HemoZym NK, Hemozym Bio N 5 ) in combination with biofertilisers Lumbrical and Boneprot, as well as the influence of certain agrometeorological conditions on the phenological growth of pepper cv. 'Sofiiska Kapiya'. This experiment was carried out in 2009 -2011 on the experimental fields of the Agroecological Centre at the Agricultural University Plovdiv (Bulgaria). The pepper was grown using existing technology for mid-early field production, according to the principles of organic agriculture. The agroclimatic characteristics were taken on the basis of data of twenty-four-hour performance of meteorological factors. In the three years of the experiment the temperature conditions during the period of active vegetation of the pepper (June -July -August) were above the average, which was in conjunction with the global trends. The application of biofertiliser Emosan, in combination with basic fertilization with biofertilisers Boneprot and Lumbrical and under the impact of suitable agrometeorological conditions, had a positive impact on the pepper plants. Pepper plants showed earlier entry into the main phenophases under field conditions of organic farming.

Effect of Organic Nutrients and Bio Fertilizers on Soil Parameters and Nutritional Content of Amaranth

“…These hormones assisted to speed up the process of carbohydrate synthesis. Because vitamin C is a sugar acid, its synthesis is encouraged by the application of organic fertilizers [9]. Inoculation with phosphate solubilizing biofertilizer helpful in assimilation of carbohydrates and which in turn increased the synthesis of ascorbic acid [10].…”

Application of Liquid Organic Pusri Fertilizer (LOPF) and Inorganic Fertilizer on Ultisols Planted With Red Chili (Capsicum annuum L.)

“…These bacteria have a positive effect on the vegetative growth of red chili plants on Ultisol, presumably because of their role in increasing N and dissolving P and K as well as stimulating the plant growth. In line with the research from [15], biological fertilizer containing microorganisms tend to provide nutrient needs for plants so that plant growth could be more optimal.…”

Fertilization of wheat with liquid organic fertilizers under the conditions of a pot vegetation experiment

“…An alternative to chemigation in agriculture is the introduction and use of organic products that are used in organic farming not only as a substitute for inorganic fertilization (Vlahova, 2013), but also as a means of biological protection of plants from diseases (Yankova et al, 2009).…”
