ABSTRACT In the present study, seven fertilizer treatments [T1, 50% NPK; T2, 100% NPK (Recommended dose of fertilizer, 200–65.4–124.5 kg N-P-K ha−1); T3, 150% NPK; T4, 100% PK; T5, 100% NK; T6, 100% NP and T7, control (zero NPK)] with four replications were assessed in the new alluvial soil zone (Entisols) of West Bengal, India. The objectives of the study were to generate information on potato productivity, profitability, indigenous nutrient supply and net gain/loss of NPK in post-harvest soil. Plants grown under higher NPK supply resulted in higher tuber yield and there were significant (p ≤ 0.05) reductions in total yield with nutrient omissions. Nutrient−limited yields were 19.78, 2.83 and 1.77 t ha−1 for N, P and K, considering total tuber yield (28.24 t ha−1) obtained under 100% NPK as targeted yield. Indigenous nutrient supply of N, P and K were estimated at 24.1, 22.34 and 110.22 kg ha−1, respectively that indicates higher K−supplying capacity of experimental soil as compared to N and P.

Field experiment was conducted on clay loam soil during winter season of 2010–2011 and 2011–2012 at the Research Farm, Bidhan Chandra Krishi Viswavidyalaya, West Bengal to study the influence of sulphur (S) levels and irrigation on quality and yield of mustard (cv. Varuna, T-59). Results revealed that yield attributes and yield of crop were highest with 60 kg S/ha, mostly at par with 45 kg S/ha. Double irrigation at flower initiation (30 days after sowing (DAS)) and siliqua development stages (60 DAS) was best with respect to growth, yield attributes, yield, S uptake and oil percent in seed. Effects of both S levels and irrigations on glucosinolate and fatty acid content were non-significant except on progoitrin. The erucic:oleic acid ratio was inversely related to the subsequent increase in S doses, thereby suggesting the qualitative improvement of oil with S application. Oil percent has a negative correlation with sinigrin and gluconapin content. The uptake of S was positively correlated with oleic acid content but showed lower or even negative correlation with other fatty acids. Therefore, irrigation (twice at 30 DAS and 60 DAS) in combination with 45 kg S/ha are recommended for improving yield attributes, yield, oil percent and S uptake of Indian mustard.

The response to sulphur (S) and irrigation of mustard although site-specific, is less studied across sites. Economics and greenhouse gases (GHGs) emissions are other important considerations for developing resource-efficient technologies, but hardly studied in mustard. The objectives of this study were to appraise productivity, economics and GHGs emissions under three irrigation regimes combined with four levels of S, laid out in a split plot design with three replications. Results showed that two irrigations at 30 and 60 DAS combined with 60 kg S ha⁻¹ resulted in highest gross and net returns, which were 30.9 and 37.2% higher than that in single irrigation at 30 DAS, and 47.2 and 68.0% higher than that in single irrigation at 60 DAS without S application, respectively. Estimated GHGs emissions from common inputs (machinery, diesel, fertilizer and insecticides) of mustard were 1486.2 kg CO₂ eq ha⁻¹ with greater share (95%) of fertilizer. Econometric analysis predicts that 1% increase in irrigation and S use will lead to 10.29 and 9.98% increase in mustard yield, respectively.

This study is a synthesis of information on growth, yield, and boron-use efficiency of hybrid sunflower (cultivar Aditya) in an inceptisol (Gangetic alluvium) of West Bengal, India, under varied proportions of soil and foliar-applied boron. Foliar spray of boron (B), under all circumstances, performed better than soil application of B fertilizers with regard to sunflower seed and total dry-matter yield, B uptake, and B-use efficiencies, while 0.2 percent foliar B spray was associated with greatest B recoveries, B-use efficiencies, and sunflower seed yields in the experimental years.

ABSTRACT A 2-year field trial was conducted in processing grade potato cv. Kufri Chipsona-3. The treatments comprised recommended dose of fertilizer (RDF) (200:150:150 N:P2O5:K2O kg ha−1) with or without boron (B) application (soil and foliar). The results revealed that B fertilization significantly increased tuber number and yield. Three sprays of 0.1% boric acid (at 40, 50 and 60 days after planting) produced the maximum number and yield of tubers and enhanced B uptake in potato tuber, haulm as well as in total plant accounting 85.8, 182.0 and 169.8% more than control, respectively. The same treatment came up with greatest net return and benefit: cost ratio. B fertilization exerted significant influence on available N and B status of post-harvest soil, while the effect was non-significant on available P and K. Results suggest that right dose and method of B application is vital for optimizing tuber yield and B-use efficiency for processing grade potato.

ABSTRACT Weeds pose a major challenge at the initial stages of sugarcane and when uncontrolled cause high yield losses. This study was undertaken to define a better and cost-effective weed management strategy. We compared ametryn + trifloxysulfuron-sodium (hereafter referred to as trifloxysulfuron) ready-mixes with single applications of trifloxysulfuron, atrazine and 2,4-D for efficacy, non-target and residual toxicities, yield and profitability in a sugarcane–green gram rotation. Results showed that a density of 100 weeds m−2 could reduce sugarcane yield by 18.4 t ha−1. The ready-mix ametryn + trifloxysulfuron (1097.3 + 27.8) g a.i. ha−1 applied 15 days after planting (DAP) caused reductions in weed density by 88.2%, 90.9%, and 90.3%, and weed biomass by 68.0%, 53.8%, and 56.2% compared to unweeded control at 30, 60, and 90 DAP, respectively. Consequently, the sugarcane yield, system productivity, and net returns were increased by 92.1%, 43.5%, and 1515%, respectively due to this ready-mix. It increased system productivity by 23%, 17.2%, and 22.7% compared to trifloxysulfuron, atrazine, and 2,4-D treatments, respectively. This ready-mix may be recommended in sugarcane. This would reduce weed seed bank and herbicide application cost by 50%, and prevent/delay weed shift and resistance.

Aims: More than 54% of soils in West Bengal are Zinc (Zn) deficient and therefore, Zn−fertilization is assumed to play a key role not only for increasing potato yield but also for combating wide spread deficiency of micronutrients (mainly Zn) in many potato growing areas of the state. Original Research Article Banerjee et al.; IJPSS, 16(2): 1-13, 2017; Article no.IJPSS.33844 2 Place and Duration of Study: A two-year field experiment was conducted during winter 2013-14 and 2014-15 at to assess the advantages of Zn nutrition in potato cv. Kufri Jyoti under alluvial soil (Entisols) of West Bengal, India Methodology: The experiment was laid out in randomized block design (RBD) having five treatments and four replications The potato was fertilized with five zinc levels (0, 1.5, 3.0, 4.5 and 6.0 kg Zn ha) through zinc sulphate heptahydrate i.e. ZnSO4, 7H2O (commercial grade Multi-Zn contained 21% Zn) at the time of planting. A uniform dose of NPK at 200:150:150 kg ha RDF was applied in all the plots in the form of urea (46% N), single super phosphate (16% P2O5), and muriate of potash (60% K2O). Results: Application Zn fertilizer at 4.5 kg ha recorded significantly higher germination %, plant height, leaf area index (LAI), dry matter accumulation (DMA) and number of tubers hill. Total number and yield of tuber ha were also changed significantly (P≤ .05) with the levels of Znfertilization. Quality parameters like total soluble solids (TSS), total acidity, ascorbic acid, starch and amount of total sugar contents of fresh potato tuber as well as organoleptic quality of chips (colour) also influenced significantly (P≤ .05) with varied levels of Zn fertilization. Conclusion: Results suggest that application of 4.5 kg Zn ha in combination with recommended dose fertilizer (RDF) of NPK (i.e. 200:150:150 kg ha) is vital for optimizing yield components, yield and quality of potato (cv. Kufri Jyoti) in trans-Gangetic plains of West Bengal, India.
