No full textAn on-site experiment was carried out at the Bangladesh Rice Research Institute (BRRI). The objective was to assess the most appropriate blend of organic and inorganic fertilizers for the Boro-Fallow-Transplanted Aman rice cropping pattern. An experiment was carried out at the BRRI Farm in Gazipur, Bangladesh to assess rice yields, nutrient absorption, and balance. The nutrient management practices included absolute nutrient control (T1), the recommended chemical fertilizer dose by BRRI (T2), a combination of kitchen waste (3 t/ha) and 50% of the recommended BRRI fertilizer dose (T3), a combination of cow dung bio-slurry (3 t/ha) and 50% of the recommended BRRI fertilizer dose (T4), and a combination of poultry litter (3 t/ha) and 50% of the recommended BRRI fertilizer dose (T5). The practices were evaluated using a randomized complete block design with three replications conducted over two consecutive years. The performance of Poultry litter with 50% BRRI-recommended fertilizer (T5) and BRRI-recommended fertilizer dosage (T2) has been superior in all parameters. The same approaches (T5) and (T2) demonstrated the highest absorption of nutrients by rice crops. The observed N and K balance exhibited a negative trend but with a lesser degree of negativity. Additionally, a lower level of deficit was seen in the T5 treatments. The T5 treatment exhibited a surplus of P, while other treatments showed a deficit of P. This research shows that poultry litter (3 t/ha) combined with 50% of the fertilizer suggested by BRRI is enough and acceptable for a sustainable rice yield

From these results, it concluded that combined foliar application of Mg, Fe, Zn and B is not only most effective for getting higher production and also better quality fruits of Acid lime under Alfisols of Andhra Pradesh
Economic and Yield Gap Analysis of High Yielding Ragi Varieties Under Rainfed Situations of Tiruvallur District of Tamil Nadu, India
No full textRagi is an important millet crop cultivated in about 82919 ha in Tamil Nadu and accounts for 77% of the total millet cultivated area. It is rich in protein, dietary fibre, minerals like calcium and iron and has been recommended for diabetes and heart diseases. Ragi is being cultivated in an area of 350ha in Tiruvallur district of Tamil Nadu and has a potential to be expanded in terms of cultivable area under this major rice growing district owing to the changing climatic situations. Farmers of the district could realize only low yields and gross returns due to cultivation of local varieties and non adoption of improved package of practices. Hence the present study was undertaken by Krishi Vigyan Kendra, Tiruvallur situated in Tirur village in order to assess the performance of high yielding ragi varieties and to perform the yield gap and economic analysis under improved management practices and to motivate the farmers in cultivating high yielding ragi varieties. The improved varieties ML 365 and CO (Ra) 15 performed better than the local cultivar Balamani and gave higher yields, net returns and BC ratio. However the technology gap noticed under the demonstration could be abridged by improving the soil nutrient status and following improved package of practices. ML 365 recorded higher yield and returns and has high effective gain in comparison to CO (Ra) 15 and hence could be recommended for cultivation in Tiruvallur district
Effect of Organics on Yield and Yield Components of Chia (Salvia hispanica L.)
No full textChia (Salvia hispanica L.) is a new emerging crop as functional food. Its seeds are richest source of omega-3, antioxidant, calcium and are known to prevent heart disease, diabetes and cancer. Owing to its nutraceutical and therapeutical values, the studies on its organic production are very essential under Indian condition. Therefore, an experiment to determine the influence of organic fertilization on growth and yield of chia was done at Jabalpur, Madhya Pradesh during 2018-19 and 2019-20. The recommended fertilizers dose (RDF) 57.5:40:24 NPK kg ha-1 with FYM 10 t ha-1 was compared with fourteen treatment combinations of organic manures viz., vermicompost (V), bio gas spent slurry (BSS) and Neem cake (Nc) at 25% or 50%N equivalent dose of RDF and organic supplements namely, microbial consortia (M), Jeevamrita (J) and humic acid (H).
The maximum plant height, number of branches per plant, number and weight of spikes per plant, spike weight, dry matter, seed yield per plant and seed yield per hectare were higher under RDF which was at par with FYM50V25BSS25MJH, RDFM, RDFJ. During first year, RDF recorded the higher yield (835.67 kg ha-1) followed by RDFMJH (680.93 kg ha-1), RDFJ (665.84 kg ha-1), FYM50V25BSS25H (616.19 kg ha-1) and FYM50V25BSS25 (603.57 kg ha-1). During first year, chia resulted in lower yield in comparison to second year in all the treatments. The reproductive phase, blooming to seed filling was found sensitive to frost. During second year RDFMJH gave higher yield (1201.65 kg ha-1) and was at par to FYM50V25BSS25M (1186.28 kg ha-1), FYM50V25BSS25J (1165.71 kg ha-1) and RDF (1165.43 kg ha-1). Therefore, the RDF can be substituted by organic manures combination viz. FYM 10.7 t + vermicompost 1.07 t + biogas spent slurry 1.68 t ha-1 along with microbial consortia or with Jeevamrita

Physical and Chemical Properties of Cocoa Pod Husk Dumpsites in Etung Cocoa Farms Nigeria
No full textAssessment of some physical and chemical properties of cocoa pod husk dumpsites in Etung, Nigeria, was carried out to ascertain the particle size distribution, nutrients, and some soil fertility indices. Five cocoa-growing communities were purposely selected for sampling. Soil samples were collected at 0–25 cm and 25–50 cm in each cocoa farm dumpsite and non-dumpsites in the cocoa plantations. A total of 20 samples were collected, processed, and subjected to standard laboratory analysis. The results obtained indicated that there was no difference in soil textural classes between dumpsites and non-dumpsites on the plantations. pH in dumpsites ranged from 4.2 to 6.0, and plantation soils ranged from 3.9 to 5.6 Electrical conductivity. Surface dumpsite soils ranged from 0.0068 to 0.941 ds/m, and plantation soils ranged from 0.084 to 0.0816 ds/m. Total N in dumpsites ranged from 1.14–1.98% and 0.73–1.08% in plantation soils. P in dumpsites ranged from 9.61 to 13.42 mg/kg and 5.98 to 11.34 mg/kg in plantation soils. Exchange cations were higher in dumpsites than plantation soils. The students T-test (t-0.05) showed significantly higher pH, N, P, organic C, and CEC in dumpsite sites than plantation soils and significantly higher surface than subsurface soil depth. Though nutrient levels were higher in cocoa pod husk dumpsites, the levels were within the sufficiency threshold levels. The higher organic carbon content of cocoa pod husk dumpsites is an indicator of higher soil organic matter content for good sorption and retention of both macro- and micro-cationic nutrients to prevent their excess release that could degrade the soils

A randomized block design was employed with eight treatments and three replications. A randomized block design was employed with eight treatments replicated thrice. Results revealed that, Combined soil application of biochar @ 10 t ha-1 and FYM @ 10 t ha-1 (T8) recorded higher leaf yield per hectare (13.07 t ha-1) and it was on par with T7 (12.61 t ha-1) which received soil application of biochar @ 7.5 t ha-1 and FYM @ 10 t ha-1. The lowest leaf yield of 10.45 t ha-1 was recorded in control which was devoid of biochar. Among different treatments, significantly higher uptake of primary nutrients (Nitrogen, phosphorus and potassium of 90.68, 9.07 and 47.10 kg ha-1, respectively) secondary nutrients (calcium, magnesium and sulphur of 44.48, 17.26 and 9.75 kg ha-1, respectively) and micronutrients (iron, manganese, zinc, copper and boron of 748.20, 153.22, 139.34, 60.92 and 54.25 g ha-1, respectively) by mulberry were recorded in the treatment (T8) which received soil application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and followed by T7 which received biochar @ 7.5 t ha-1 + FYM @ 10 t ha-1 and found superior over other treatments. The control with no biochar application recorded lower nutrients uptake by mulberry crop. The findings revealed that utilization of mulberry stalk as a biochar has positive effect on nutrient uptake by mulberry crop and it could partly replace chemical fertilizers and promote organic farming in a circular economy concept
Influence of Soil Additives (Gypsum and Dolomite) on Peanuts Productivity and Soil Properties: A Review
No full textAlthough India is steadily progressing in oilseeds production, but the average yields of most of the oilseeds like groundnut are still extremely low when compared to those prevailing in other countries of the world. This is because oilseeds are cultivated mostly in marginal and sub-marginal land of semi-arid areas with very less management, hence remain vulnerable to vagaries of nature. Among oilseed crops groundnut is an important source of vegetable oil and protein. Lack of appropriate management practices leads to decreased yields of the crop. Applications of amendments like gypsum and dolomite based on soil pH is necessary to provide a better environment for roots and plant growth
