Integrated nutrient management in sorghum (Sorghum bicolor) and its residual effect on wheat (Triticum aestivum)

Abstract: 1997-98 and 1998-99 to determ ine the most appropriate combination of organic manure, fertilizers and biofertilizers for sorghum [Sorghum bioc%r (L.) Moench] and to assess their carry-over effect on succeeding wheat (Triticum aestivum L. emend. Fiori & Pao!.) crop. An application of 10 tonnes farmyard manure/ha increased grain and fodder yields of sorghum by 18.52 and 9,42%, respectively, compared with no farmyard manure application. Nuitrients uptake (N, P and K) by sorghum was also increased by 15.4, 14.2 and 16.0% respectively, with farmyard manure application. Significant improvement in grain and fodder yields was observed up to 75% recommended dose of fertilizer. Successive increase in fertility levels either 75% or 100% recommended dose of fertilizer significantly enhanced N (157.0 kg/ha), P (47 kg/ha) and K(247 kg/ha) uptake by sorghum. Inoculation. of Azospirillum alone and in combination with phosphate-solubilizing bacteria significantly increased grain and fodder yields qf sorghum. Grain and straw yields of wheat increased by 8.81 and 6.61 % owing to residul effect of farmyard manure. Application of 75% to 100% recomlnended close of ffertilizer to sorghum significantly incresed grain and straw yields of wheat. Application of farmyard manure increased net gain from sorghum;-wheat sequence by Rs 3 428/ha. Miximum net returns of Rs 49 33,51 ha were obtained from sorghum-wheat sequence under 100% recommended dose of fertilizer, followed by Rs 47 229 under 75% recommended dose of fertilizer compared with Rs 38 231 under the control. A net gaiih of RS 2 337/ha was also obtained owing to dual inoculation of Azospirillum and phosphate-solubilizing bacteria.

Effect of integrated use of nitrogen on yield and n uptake of maize crop

Abstract: The present field studies investigated the effect of the integrated use of mineral N and organic N sources (Farm yard manure, Poultry manure and Filter cake) on maize crop. Field experiment was carried out on silty clay loam soil at NIFA Tarnab Peshawar Pakistan during 2005-06. There were 17 treatments with four replications using maize variety Azam as a test material in RCB design. Statistical analysis of the data revealed that integrated application of organic N sources (farmyard manure, poultry manure, filter cake) and mineral N source (urea) resulted an upward trend in the yield of maize crop. Maximum biomass, (9554 kgha -1 ) and stover yield (8136 kgha -1 ) of maize were obtained from those treatments where 100% (FYM) was used. Maximum grain yield (1838 kgha -1 ) was recorded from treatment where 25% farmyard manure (FYM) and 75% mineral nitrogen source (urea) were used. Agronomic efficiency and nitrogen use efficiency was also found higher in the treatments where 25% N from farmyard manure (FYM) and 75% N from mineral N source (urea) was applied. It was concluded that combination of 75% mineral N source and 25% organic N sources (urea) are the best combination for sustainable yield.

Adsorption Capacities and Availability of Phosphorus in Soil Solution for Rice Wheat Cropping System

Abstract: 2 Abstract: The present study was conducted to measure the phosphorus (P) adsorption capacities in a typic Camborthid (Bhalike series) soil of rice tract of Punjab, Pakistan to compute P fertilizer quantities for field application, internal and external P requirements of the wheat, sorghum fodder and rice, Phosphorus Fertility Build-up Factor (PFBF) and level of phosphorus build-up. The soil selection was based on clay percentage, calcium carbonate content. The data showed that soil was free from salinity and sodicity, deficient in organic matter and adequate in available potassium. Sorption isotherm was constructed in the laboratory by equilibrating and shaking 2.5 g soil with 25 ml of 10 m M CaCl containing 0, 5, 10, 15, 20, 40, 60 and 80 g P mL 2 1 as KH PO for 24 h. Sorption data was fitted into linear form of Langmuir and modified Freundlich models and 24 P adsorption capacity was determined from the equations. Theoretical doses were computed from modified Freundlich model for field application. The studies were conducted in permanent layout according to Randomized Complete Block Design (RCBD) with three replications. Different theoretical P doses were applied in the field to develop soil solution P level of 0.01, 0.02, 0.03, 0.04, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.40 and 0.50 mg L alongwith a control of native P soil solution. An overall check (NK = 0 with native P) was also kept. 1

Effect of FYM and fermented liquid manures on yield and quality of chilli (Capsicum annuum L.)

Abstract: A field experiment was conducted at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad on a Vertisol to study the effect of FYM and fermented liquid manures on yield and quality of chilli during kharif 2007. The experiment consisted of 12 treatment combinations with two factors; factor one consisting of manures (FYM equivalent to RDN (M1), RDF (M2) and FYM equivalent to RDN+RDFYM (M3)) and the factor two liquid manures (Beejamrut + Jeevamrut (L1), Panchagavya (L2), Beejamrut + Jeevamrut + Panchagavya (L3) and Control (L4). The treatments were replicated thrice and experiment was laid out in Randomized Complete Block Design. Application of manures and liquid manures recorded significantly higher growth, yield and quality parameters of chilli. Treatment M2 recorded significantly higher dry chilli yield (8.33 q/ha) over rest of the manures. Among liquid manures, treatments L3 and L2 recorded significantly higher dry chilli yield (8.52 and 8.01 q/ha, respectively) over control (6.40 q/ha), the values for growth and other yield components were also significantly higher in these treatments. Treatments M3 and M1 recorded higher quality parameters Viz., ascorbic acid content, oleoresin and colour value by 14.43: 9.19, 8.40: 5.33 and 14.18: 11.77 per cent, respectively over M2. Among liquid manures, L3 and L2 recorded higher ascorbic acid, oleoresin and colour value by 8.02: 6.74, 7.89: 7.00 and 8.25: 7.17 per cent, respectively over control (121.89 mg/100g, 203.01 ASTA units and 301.71 ASTA units, respectively). A significantly higher dehydrogenase activity, available macro (N, P and K) and micronutrients (Cu, Zn, Fe and Mn) were recorded with M3 and M1. Dehydrogenase activity was also found to be significantly greater with liquid manures. Greater uptake of nutrients was recorded with M2. However, M2 and L3 recorded significantly higher yield, net returns and B: C ratio.

Effect of different organic treatments on ex situ conservation of Polygonatum cirrhifolium Royle

Abstract: Polygonatum cirrhifolium Royle (Meda), a herb belonging to the Liliaceae family, is known for its medicinal, cultural and ethno-botanical uses. However, due to its great market potential, it is harvested and grown in an uncontrolled way; overexploitation has caused the decline of the herb from its natural habitat. Since finding new organic treatments can help conserve the plant, a 2-year field experiment was undertaken to study the effect of different organic fertilizers and the nature of nursery beds on the survival, morphological growth and yield of this plant. The observations were recorded in 15-day intervals. The results show that yield was lower in control beds when compared with forest litter, farmyard manure and vermicompost in all type of beds prepared in rows, furrows and plain. The yield was highest at beds located at plantation with furrows which were supplemented with forest litter. Thus, it can be concluded that the cultivation of P. cirrhifolium is optimal in beds with rows and furrows (pla...
