: The Costal Saline Zone (CSZ) of West Bengal, India is dominated by rice-fallow-fallow system cropping system. Only 4% of the cultivated area of the coastal zone can be irrigated with available sweet water. To cope up with the present situation is introduction of new high value crops to catch the fallow winter period emphasizing on water saving technologies. In this way mono-cropped saline soils of coastal region can be converted into multiple cropping through the adoption of zero tillage potato technology. Soils of the CSZ show multi-nutritional deficiencies and these deficiencies adversely affect the crop. To address this issue, field experiment was conducted in winter season of 2016–2018 in CSZ of West Bengal, India with the focal objectives of studying the feasibility of potato under zero-tilled-mulched condition in CSZ of West Bengal; assessing the effect of foliar nutrient management practices on growth, yield, quality and economics of potato. The foliar nutritional supplementation with 2% Urea at 30 & 50 days after planting (DAP) of potato along with 0.1% Boron at 30 DAP not only increased tuber number and yield but also quality parameters of potato tuber such as TSS, tuber hardness, vitamin C etc. were significantly increased. It may thus be concluded that 2% Urea at 30 & 50 at DAP of potato along with 0.1% Boron at 30 DAP as foliar application is the best foliar nutrient management option for potato grown under zero tillage and mulching in coastal saline soils of West Bengal, India.

The review of effects of excessive soil water on performance of various vegetable crops and selected field crops indicates that in areas where temporary flooding hazards are expected during the growing season, crops can be selected on their relative ability to tolerate excessive moisture. Field crops are generally less sensitive than vegetable crops in terms of yield. In addition to the choice of crop species, planting dates could be shifted when possible by delaying dates of sowing or planting to avoid probable periods of flooding during the sensitive growth stages. In most instances, crops are more sensitive at their early developmental phase than at the later stages in terms of yield. Soil management practices like ridging and furrowing or making raised beds before planting is recommended. In addition, amelioration with foliar application of chemicals like nutrients, growth hormones and fungicides is also recommended to overcome nutritional deficiencies, hormonal imbalances and disease infections. Every effort of amelioration should be exerted at the earliest opportunity, since water damage to crops becomes more severe with longer flooding duration.

A field experiment was conducted during kharif, 2016 and 2017 at S.V. Agricultural College farm, Tirupati to study the influence of spacing, nutrient and weed nutrient management practices on growth and yield of foxtail millet. Significant effects were noticed on growth and yield components viz., plant height, number of panicles m-2, weight of the panicle, grain weight panicle-1, grain and straw yield of foxtail millet. Among different plant geometries tried, closer spacing of 20 cm x10 cm registered taller plants, higher number of panicles m-2, higher grain and straw yield, where as the weight of the panicle, grain weight panicle-1 were found to be highest with 30 cm x10 cm. Among the micronutrient management practices, foliar application of ZnSO4@ 0.5% twice at the time of flowering and at grain filling stage along with 100% RDF registered taller plants as well as higher grain yields.Hand weeding at 20 DAS and 30 DAS outperformed other weed management practices. This was followed by pre-emergence application of butachlor @ 1 kg a.i ha-1 with one hand weeding at 30DAS.The study concluded that the closer spacing of 20cmx 10cm, foliar application of ZnSO4 at the time of flowering and 20 days after flowering along with RDF and hand weeding twice at 20 DAS and 30 DAS resulted in higher productivity of foxtail millet.

A field trial was carried out during July month of kharif and October month of rabi seasons of 2013-14 and 2014-15 at Agricultural Research Station, Bheemarayanagudi to study the effect of nutrient management through target yield approach on uptake and soil microflora in maize – wheat/chickpea sequence cropping system under different tillage practices. The results indicated that the yield parameters of maize, wheat and chickpea at harvest did not influence due to tillage practices. All these yield parameters were relatively higher in zero tillage with mulch at 5 t ha-1 when compared to conventional tillage. Grain and stover yield of maize did not differ significantly due to different tillage management practices. But, zero tillage with mulch at 5 t ha-1 produced relatively higher yield (65.9 q ha-1) than the zero tillage (64.3 q ha-1) followed by conventional tillage (55.8 q ha-1). The higher organic carbon and soil microflora at different stages were noticed with zero tillage with mulch at 5 t ha-1. The higher available NPK and their uptake by maize crop were also recorded in zero tillage with mulch at 5 t ha-1 followed by zero tillage compared to conventional tillage and zero tillage. The lower available NPK and their uptake by maize crop were recorded in conventional tillage and RDF. Further, due to nutrient management through target yield approach, the yield parameters of maize were differed significantly. Target yield of 10 t ha-1 exhibited significantly higher yield attributes at harvest when compared to other treatments except the targeted yield of 8 t ha-1 and 150% RDF. The lowest values of these attributes were recorded in farmer’s practice of nutrient management followed by RDF. The grain yield and stover yield (69.9 q ha-1and 89.5 q ha-1, respectively) of maize was significantly higher with a targeted yield of 10 t ha-1 followed by targeted yield of 8 t ha-1 and 150% RDF. The lowest grain and stover yield (53.6 q ha-1 and 74.3 q ha-1, respectively) was recorded in farmers practice followed by RDF. Significantly higher soil microflora, available NPK and their uptake by the maize crop was noticed in target yield of 10 t ha-1 followed by targeted yield of 8 t ha-1 and 150% RDF as compared to other treatments. The lowest soil microflora, available nitrogen, phosphorus, and potassium (NPK) and their uptake by the maize was recorded in farmers practice followed by RDF. The same trend was followed statistically for organic carbon due to different treatments. Non significant differences for grain and stover yield of maize was recorded due to interaction of tillage and nutrient management practices. Similar trend was also followed due to interaction of tillage and nutrient management practices for succeeding wheat and chickpea. The yield and yield parameters of wheat and chickpea did not differ due to tillage practices and target yield approaches followed for maize. Maize equivalent yield of wheat and chickpea and system productivity were followed same trend as that of maize yield. Among different tillage practices, zero tillage and zero tillage with mulch at 5 t ha-1 were recorded maximum net returns and higher BC ratio. Similarly, among different nutrient management practices, the target yield of 10 t ha-1 followed by targeted yield of 8 t ha-1 was recorded maximum net returns and higher BC ratio as compare to other treatments.

Aim: Cereal-legume cropping system has been proved to be one of the best alternatives for a productive as well as profitable farming in West Bengal. Maize is an important cereal crop which is widely grown during rainy (kharif) season throughout the State. While garden pea, a short duration winter (rabi) season vegetable, can easily fit in any existing cereal-legume cropping system. The present nutrient management strategies solely relay on NPK based chemical fertilizer application which results in the gradual deterioration in soil physical and chemical properties and stagnant crop yield. To maximize production level by spraying extracts of natural products that contain stimulants, is a strategic move to overcome the ill effects of the use of excessive doses of inorganic fertilizer. Methodology: The present field experiment was conducted in Nadia district, West Bengal during rainy and winter season of 2016-17 and 2017-18 to assess the impact of seaweed extracts on crop growth and productivity under maize-garden pea cropping sequence. There were four concentrations of Kappaphycus seaweed sap (K-sap) (5.0 and 10%); two concentrations of GA3 free K-sap (5.0 and 10%); two concentrations of Gracillaria seaweed sap (G-sap) (5.0 and 10%) and a control [Recommended dose (RD) of NPK only]. Results: Experimental results revealed that the foliar application of K-sap (10%) along with RD of NPK resulted in an impressive performance of both the crops in terms of growth (plant height, biomass, crop growth rate), yield attributes and yield, which was closely, followed G sap (10%). Throughout the growth period of garden pea, plants received recommended dose of fertilizer supplemented with K-sap at 10% concentration recorded significantly highest biomass production (56.94, 170.02 and 309.37 g m-2 respectively). Conclusion: This may be concluded that the foliar application of 10% K-sap along with RD of NPK can be recommended for maize-garden pea cropping sequence.

The experiment was conducted in a greenhouse during 2017 and 2018 growing seasons to evaluate the impact of the shading and various nutrition programs on mitigating heat stress, reducing the use of chemical minerals, improving the reproductive growth and yield of tomato plant. Split-plot within Randomized Complete Block Design (RCBD) with three replications was conducted in this study. Shading factor was allocated in the main plots and the nutrition programs distributed randomly in the subplots. Results indicate that shading resulted in the decrease of daytime temperature by 5.7˚C as an average for both seasons; thus a significant increasing was found in leaf contents of macro nutrients (Nitrogen, Phosphorous, and Potassium), and micro nutrients (Iron, Zinc and Boron), except the Iron content in 2018 growing season. Furthermore, shading improved significantly the reproductive growth and tomato yield. Among the plant nutrition programs, the integrated nutrient management (INM) including the application of organic substances, bio inoculum of AMF and 50% of the recommended dose of chemical fertilizers; lead to the enhancement of nutrients content, reproductive characteristics and plant yield. Generally, combination of both shading and INM showed positive effects on plants nutrient status and persisting balance on tomato flowering growth and fruits yield.
