The experiment was carried out at the District Seed Farm, Adisaptagram, Hooghly (West Bengal), India during two consecutive winter seasons of 2011-12 and 2012-13 to find out optimum N dose of potato cultivars for getting higher yield as well as to identity efficient potato cultivars regarding N use. Average yield of potato cultivars increased significantly with increase in N supply up to 225 kg N ha-1, then tended to decrease slightly as nitrogen levels increased further. Tuber yield of cultivars Kufri Shailja and Kufri Jyoti was increased significantly with increase in nitrogen level up to 225 kg N ha-1 and further addition of N decreased yield. Yield of Kufri Himalini was increased with increase in N level up to 300 kg N ha-1 but the yield increment from 225 kg N ha-1 to 300 kg N ha-1 was not significant. Application of less N decreased average potato tuber yield by 5.3, 18.7 and 65.1% with 150, 75 and 0 kg N ha-1 respectively, compared to 225 kg N ha-1. Nitrogen use efficiency (NUE) decreased towards higher N levels for all cultivars. NUE of Kufri Himalini was higher at all N levels. The results revealed that irrespective of cultivar 225 kg N ha-1 was the optimum for getting higher tuber yield of potato and cultivar Kufri Himalini was the most efficient in case of N use.SAARC J.

A field experiment was conducted at Regional Research Station, Karnal, CCS Haryana Agricultural University during spring 2017 to study on different planting method and nitrogen level on growth parameter and nitrogen use efficiency of sugarcane. The experiment was conducted in split plot design with three replications. The treatments comprises of four methods of planting viz. conventional planting at 75 cm (M1), half ridge open furrow irrigation planting at 75 cm (M2), wide bed and furrow paired row planting (M3) and wider planting (M4) at 120 cm and six different nitrogen levels viz. control (N1), 75 (N2), 100 (N3), 125 (N4), 150 (N5), 175 kg N ha-1 (N6). Germination count was significantly affected by planting methods at 30 and 45 DAP, however, it was found to be non significant among nitrogen levels. Neither the planting methods nor the nitrogen levels had any significant effect on nutrient use efficiency, brix, pol, juice purity and commercial cane sugar. Significantly higher sugar yield (11.9 t/ha) was recorded in wide bed and furrow paired row planting which was 22.7, 8.2, and 6.3 per cent higher than conventional, wider planting and half ridge open furrow method, respectively. Lower sugar yield (9.7 t/ha) was recorded in conventional method. Among nitrogen levels, sugar yield increases with successive increase in nitrogen application upto recommended dose of 150 kg N/ha.

Global Concern

Imbalanced use of fertilizers for agricultural production has now become a global concern. As a result, studies on how to use efficient methods to reduce nutrient applications at the same time increasing or maintaining crop yield, reducing nutrient losses and improving nutrient use efficiency are imperative. Accordingly, a pot study was conducted to evaluate whether zeolite application might improve selected soil properties, nitrogen use efficiency during maize cultivation. Among all treatments, irrespective of the nitrogen level, NUE (N recovery and agronomic use efficiency of N) showed an increasing trend with the increase of zeolite levels, nitrogen levels and their combination. The highest N recovery and agronomic NUE was obtained in N200Z7.5 (Nitrogen @ 200 kg ha-1 + Zeolite @ 7.5 t ha-1), was on par with N200Z5 (Nitrogen @ 200 kg ha-1 + Zeolite @ 5 t ha-1). N uptake by maize at harvest was highest in N200Z7.5 (Nitrogen @ 200 kg ha-1 + Zeolite @ 7.5 t ha-1).

Nutrient management is critical for rice farming because the crop is grown under diverse conditions, and in most cases, the existing nutrient management practices fail to achieve an attainable yield target. During recent years site specific nutrient management gained importance for a target yield with maximum nutrient use efficiency. Sufficient research work has not been carried out in this direction so far in the rice–rice–pulse (black gram) sequential cropping system under the red and lateritic belt of West Bengal, India. A multi-locational field experiment was conducted from July 2013 to June 2015 at three different locations, namely, Guskara (Burdwan district) and Benuriya (Birbhum district) villages in farmers’ fields and at the university farm of Visva-Bharati, Sriniketan, West Bengal, India. The performance of nutrients was tested by providing ample doses of N, P, K, S, and Zn compared to the omission of these nutrients. The growth parameters, such as crop biomass production, leaf area index, and number of tillers, and yield attributes and yield were influenced by nutrient management treatments. Application of 100% of N, P, K, S, and Zn resulted in its superiority to other nutrient management options studied, and a similar trend was also noted with the treatment in the expression of nutrient use efficiency (NUE) and nutrient response (NR). The available N, P, K, S, and Zn contents in soil increased steadily due to the increase in fertilizer application. The study concluded that optimization of NPK in the rice–rice–pulse cropping system on target yield along with need-based S and Zn application was beneficial for higher productivity.

Field experiments were conducted during rabi seasons of 2011-12, 2012-13, 2013-14 and 2014-15 at C-unit research farm of Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India to study the effects of different levels of nitrogen on the productivity of newly released potato (Solanum tuberosum L.) cultivars under lower Gangetic plains of West Bengal. The experiment was laid out in a factorial randomized block design with four replications having ten treatment combinations viz. two levels of newly released cultivars (V1 - Kufri Himalini and V2 - Kufri Shailja) as factor A and five levels of nitrogen (N0 -0 kg ha-1, N75 -75 kg ha-1, N150 -150 kg ha-1 N225-225 kg ha-1 N300 -300 kg ha-1) as factor B. Experimental results revealed that highest tuber yield (25.77 t ha-1) was recorded with Kufri Himalini receiving 300 kg N ha-1 followed by 24.64 t ha-1 and 23.64 t ha-1 with 225 kg N ha-1 and 150 kg N ha-1 respectively which is quite higher than the state average of 22.02 t ha-1 obtained from the state recommended dose of 200 kg N ha-1, 150 P2O5 ha-1 and150 K2O ha-1. Thus recently released variety Kufri Himalini, having moderate resistance against late blight, which is a serious problem in the state at present can be a better option for the farmers of the state to raise the potato production. Kufri Himalini produced significantly higher (14.1%) total tuber yield over Kufri Shailja and it was found to be more acceptable to the farmers in terms of production of marketable tuber (> 75 g grade). Grade wise tuber yield of potato was significantly influenced by N levels. Irrespective of cultivars application of 300 kg N ha-1 along with recommended dose of P and K recorded the highest total potato tuber yield (23.55 t ha-1) which was found statistically at par with the application of 225 kg N ha-1 and 150 kg N ha-1. Nitrogen fertilization improved the tuber yield of potato by 49.5 to 82.1% over control. Kufri Himalini was more responsive to fertilizer nitrogen than Kufri Shailja as it recorded higher agronomic efficiency (AEN), apparent recovery (REN) and physiological efficiency (PEN) at all nitrogen levels. There was a positive balance of nitrogen found in all treatments. Net gain of soil N was highest with ‘Kufri Himalini’ receiving 150 kg N ha-1. Kufri Himalini gave highest net return with 300 kg N ha-1.SAARC J. Agri., 13(2): 121-130 (2015)
