Soil Test Based Inorganic Fertilizer and Integrated Plant Nutrition System for Rice (Oryza sativa L.) Cultivation in Inceptisols of Bangladesh

A field experiment was conducted at the Bangladesh Rice Research Institute, Gazipur during 2013 to study the potential of different organic materials in integrated plant nutrition system (IPNS) and soil test based (STB) inorganic fertilizer on the growth, nutrient uptake and yield of rice (Oryza sativa L.): variety BRRI dhan29. Five treatments were laid out in a randomized complete block design with four replications. The treatments were: (1) soil test based inorganic fertilizer (NPKS @ 138-7-80-3 kg ha-1), (2) cow dung (3 t ha-1), (3) poultry manure (2 t ha-1), (4) mustard oil cake (2 t ha-1) and (5) control. Organic fertilizers were applied on dry weight basis. Inorganic fertilizers were applied along with poultry manure (PM), cow dung (CD) and mustard oil cake (MOC) as IPNS. Soil test based STB fertilizer and PM in IPNS provided maximum grain yield of rice (6.11 t ha-1). Maximum plant height and tiller numbers were found in MOC treatment, while the numbers of filled grains were higher in STB fertilizer and PM treated plots. The application of different organic sources as IPNS significantly influenced the N, P, K and S uptake in rice. However, the highest N, P, K and S uptake were found in the PM treatment. The benefit cost ratio of different treatments followed the order of STB>PM>CD>Control>MOC. Considering yield potential and BCR, STB fertilizer and PM treatments were found economically profitable. However, from environmental point of view and sustainable management of soil health and crop productivity, application of PM and CD in rice-rice cropping system is recommended for rice cultivation.The Agriculturists 2016; 14(1) 33-42

Soil Test Crop Response (STCR) study was conducted during 2010-11 for autumn rice under integrated plant nutrition system (IPNS) in Inceptisols (Aeric Endoaquepts) in Jorhat district of Assam. The basic parameters were computed from the STCR data, and the fertilizer prescription equations were developed for recommending fertilizer doses in autumn rice. The nutrient requirement (NR) for producing one quintal of autumn rice was found to be 2.40 kg, 0.84 kg and 2.25 kg of N, P2O5 and K2O, respectively. The percent contribution of nutrients from soil (CS), fertilizer (CF) and FYM (CO) were calculated as 12.49, 45.31 and 32.92 for N, 13.42, 28.52 and 11.84 for P2O5 and 21.99, 47.58 and 29.76 for K2O, respectively. These equations were validated in farmers’ fields during 2012 and the variation between actual yield and targeted yield ranged from +1.36 to +5.33.The fertilizer estimates under STCR-IPNS for 3000 and 4000 kg ha−1 targeted yield recorded maximum response ratio and economic benefit in the field trial and confirmed the validity of proposed fertilizer prescription equations for autumn rice.

Tubificid worms are aquatic invertebrates, belonging to the class Oligochaeta and family Tubificidae, used as an important live food for fishes. The study was conducted to culture Tubificid worms under running water in order to develop a suitable culture media and an optimum duration of media inoculation for culturing Tubificid worms. The worms were cultured under two experiments in cemented culvert system (160×25×10 cm3) for 90 days. In the first experiment the worms were cultured in three different media designated as treatment-I, treatment-II and treatment-III. The highest yield (503.39±22.98 mg cm-2) was found at 70th day of culture duration in the culture media containing a mixture of 35% mustard oil cake, 20% wheat bran, 25% cow-dung and 20% fine sand (treatment-III). Only 1.99 kg media ingredients valued BDT 29.85 were needed to yield 1 kg worms. In the second experiment, the worms were cultured at three different intervals of media inoculation i.e., 6, 10 and 15 days interval designated as treatment-I, treatment-II and treatment-III respectively using the media found best in the first experiment. Inoculation of media at 10 days interval showed significantly (P<0.01) higher production (488.94±5.60 mg cm-2).DOI: http://dx.doi.org/10.3329/jbau.v10i2.14925 J. Bangladesh Agril.

The experiment was carried out at the research farm of Bangladesh Institute of Nuclear Agriculture, Mymensingh, Bangladesh during December 2015 to January 2016 to evaluate the effects of cow dung (CD), poultry manure (PM) and mustard oil cake (MOC) along with NPK fertilizer amendments on the growth and yield performances of red amaranth in silty loam soil. The treatments were (i) NPK (control), (ii) NPK + CD, (iii) NPK + PM and (iv) NPK + MOC. All three types of manures significantly increased the plant height and numbers of leaves plant-1, thereby fresh weight, yield compared with the control (NPK). The best results in terms of vegetable fresh yield were obtained in the following order: NPK > CD > PM > MOC. Application of MOC is not beneficial due to 30 times higher price than CD and PM. PM added NPK fertilizer combination showed higher vegetable yield (10.87 t ha-1) than CD added NPK fertilizer combination (10.17 t ha-1). PM added fertilizer combination also had almost equal investment and cost-benefit ratio in comparison with CD. The lowest marginal benefit-cost ratio (1.09) was observed in MOC added NPK fertilizer combination though it showed higher vegetable yield (11.08 t ha-1). The farmers’ can be recommended to follow NPK + CD fertilizer combination. Manures applied post soil analysis showed improves the soil physiochemical properties. Res. Agric., Livest.

This study was conducted at Ilam Municipality-2, Nepal to determine the response of organic manures on post harvest and nutrient restorative effect of cauliflower. Five manures, viz., bansoon, mustard oil cake, poultry manure, farmyard manure, and vermi-compost were evaluated. The postharvest losses, vitamin C content and soil nutrient restorative behavior were significantly highest with vermi-compost as compared to other manures. The maximum vitamin C content of 10.92 mg/100 gm was found with vermi-compost whereas the lowest of 9.66 mg/100 gm was found at farmyard manure. Moreover, the physiological losses were found to be least with vermi compost and the most with bansoon manure. Moreover, the restorative properties i.e. pH, N,P,K and organic %age were found to be significantly highest with vermi-compost as compared to other organic manures. This study concludes that vermi compost increases vitamin C content, postharvest longevity and improvement of physical and chemical properties of the soil.
