Effects of organic manures and chemical fertilizers on the yield of brinjal and soil properties

Abstract

A field experiment was conducted at the Horticultural Farm of Bangladesh Agricultural University (BAU), Mymensingh during the period from December 2004 to April 2005 to evaluate the effect of manures and fertilizers on the yield of brinjal. There were five treatments consisting of organic, inorganic and combined sources of nutrients, of which the combined treatment (60 % organic +40% inorganic) showed the best performances. The maximum branching (20.1) with the highest number fruits/plant (15.2), fruit length (14.1 cm) and fruit diameter (4.3 cm) were found combined application of manures and fertilizers. The highest yield (45.5 t ha -1 ) was also obtained from the combined application of organic and inorganic sources of nutrients. Application of mustard oil cake or poultry manure alone gave better performance compared to only chemical fertilizers. The organic matter content and availability of N, P, K and S in soil were increased by organic matter application. On the other hand soil pH was increased with chemical application than organic.

GROWTH AND YIELD OF EGGPLANT (Solanum melongena L.) ON VARIOUS COMBINATIONS OF N-SOURCE AND NUMBER OF MAIN BRANCH

“…The improvement of soil features as a result of the stable manure application has also increased the efficient N absorption by the plant. This result conforms to the research by Ullah et al (2008) that the reduced dosage of inorganic fertilizer and replaced with the organic fertilizer by the same dosage, has resulted higher weight per hectare in comparison with the application of 100% Urea. The eggplant, which has been applied by 100% Urea, has resulted lower weight per plant and per hectare.…”

“…In 2013, the national production of eggplants reduced 509,380 ton from 519,481 ton in 2011 (Directorate General of Horticulture, 2014). One of the main causes of such reduction is the decreasing fertility of the soil and organic matters in the soil (Ullah et al, 2008). According to Waseem et al (2013), the use of inorganic fertilizer in long-term has reduced physical, chemical, and biological traits, as well as organic matters in the soil, and of course, they will affect efficiency of nutrients absorption.…”

Effect of Organic and Inorganic Fertilizers on Soil Properties and the Growth, Yield and Quality of Tomato in Mymensingh, Bangladesh

“…The mixed fertilizer treatment was the best for tomato production, which could be interpreted as the release of nutrients from organic and inorganic fertilizers at different times. Fertilizer treatment (mixed or IPNS) produced a higher yield compared to organic fertilizers and inorganic fertilizers alone in cabbage [24] and in eggplant [25]. Plant height (15, 35 and 45 DAT) was recorded (cm) from the ground to the tip of stem.…”

Effect of basic fertilizer doses and liquid organic fertilizer concentration on soybean yield

“…The higher yield in tomato due to application of organic fertilizer made from cow dung and inorganic fertilizer has been reported in the literature by Solaiman and Rabbani (2006). Some researchers such as Ullah et al (2008), Reddy et al (2002), Haque et al (2012), and Ahammad et al (2009) reported that higher yield were obtained on brinjal, cabbage and mustard due to better performance of integrated nutrient management practices.
