“…However, PFP p showed the decreasing trends when P was applied with Zn, as P and Zn have antagonist effect on plant growth, which resulted in poor recovery of P [49]. In this study we have found that the PFP of applied P either alone or in combination with N and K was considerably higher in rice crop as compared to the wheat crop across the locations having different water regimes in contrary to the earlier reports that rice respond poorly to phosphorus as compared to wheat in RWCS [7,50]. This indicates that at farmer's field rice is more responsive to N and P application as farmers of the selected locations uses the readily soluble SSP as a source of phosphatic fertilizer.…”

Rice-wheat cropping system (RWCS), a lifeline for the majority of the population in South Asia is under stress, due to the imbalanced and indiscriminate use of fertilizers. Therefore, we conducted an on-farm study at eight locations (Amritsar, Katni, Nainital, Samba, Pakur, Kanpur, Ambedkarnagar, and Dindori) covering five agro climatic zones of six Indian states (Jammu and Kashmir, Punjab, Uttarakhand, Uttar Pradesh, Madhya Pradesh, and Jharkhand) to (i) calculate the partial factor productivity (PFP) and agronomic use efficiency (AUE) to judge the response of NPK and Zn on grain yield of rice and wheat in RWCS and (ii) to work out the economic feasibility of different combinations of NPK in rice and wheat. Seven fertilizer treatments: Control (0-0-0), N alone (N-0-0), NP (N-P-0), NK (N-0-K), NPK (N-P-K), NPK+Zn (N-P-K-Zn), and FFMP (Farmers Fertilizer Management Practice) were assigned to all the locations. The levels of applied nutrients were used as per the standard recommendation of the location. The average of all the locations showed that the use of NP enhances the grain yield of rice and wheat by 105% and 97% over control, respectively. System productivity of RWCS was expressed in terms of rice grain equivalent yield (RGEY), Mg ha−1. Among the locations, Samba recorded the lowest productivity of RWCS with fertilizer treatments. In contrast, the highest productivity of RWCS with fertilizer treatments was recorded at Amritsar, except with NPK and NPK+Zn fertilization, where Katni superseded the Amritsar. An approximately 3-fold productivity gain in RWCS was recorded with the conjoint use of NP over control across the locations. Overall, the results of our study showed that the balance application of NPK increased the productivity of RWCS 245% over control. Partial factor productivity of Nitrogen (PFPn) N alone in rice varied across locations and ranged from 19 kg grain kg−1 N at Pakur to 41 kg grain kg−1 N at Amritsar. PFPn of N alone in wheat also ranged from 15.5 kg grain kg−1 of N at Ambedkarnagar to 28 kg grain kg−1 N at Amritsar. However, across locations the mean value of PFPn of N alone was 29 kg grain kg−1 N in rice and 21 kg grain kg−1 N in wheat. PFPn increased when combined application of N and P sorted in both rice and wheat across the locations. Similarly, combined application of NPK increased partial factor productivity of applied phosphorus (PFPp) in both the crops at all the locations. The combined application of NPK increased the PFPk for applied K at all the location. The response of K application with N and P when averaged over the location was 114% in rice and 93% in wheat over the combined use of N and K. In our study, irrespective of fertilizer treatments, the agronomic use efficiency of applied N (AUEn) and agronomic use efficiency of applied P (AUEp) were greater in rice than in wheat across the location. With regards to the economics, the mean net monetary returns among the fertilizers treatments was minimum (INR 29.5 × 103 ha−1) for the application of N alone and maximum (INR 8.65 × 103 ha−1) for application of NPK+Zn. The mean marginal returns across the locations was in order of N alone > NK > FFM > NPK > NP > NPK+Zn.

“…Zinc plays an important role in nitrogen metabolism and formation of chlorophyll and carbohydrate, which leads to maintain photosynthetic activity for longer period and finally results in increasing the yield and yield attributes in pearlmillet (Mehta et al, 2008). Debnath et al 2015 find out that a conjoint dose of 60 kg phosphorus and 5 kg Zn /ha gave the highest grain yield of wheat than control and agronomic efficiency of P in basmati rice can be increased by using 40 kg phosphorus with 2.5 kg Zn/ha.…”

Background: Pearlmillet growing areas in country are mostly confined to coarse texture soil suffering from the problem of poor moisture retention capacity, low soil fertility and zinc deficiency. The main problem of rainfed area is uncertainty and uneven distribution of rainfall and loss of water through runoff which lead to low and unstable productivity due to moisture stress at critical stage of crop growth. At present, widespread and acute deficiency of zinc is another serious problem in arid and semi-arid region. Hence, the current study aim to find out suitable moisture conservation practices and zinc fertilization to mitigate the water stress and zinc deficiency under rainfed condition.Methods: A study on “Effect of moisture conservation practices and zinc fertilization on nutrient status and quality of pearlmillet” was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during kharif, 2017. The experiment was laid out in randomized block design (RBD) with 20 treatments and replicated thrice. The experiment consisted of five moisture conservation practices i.e. control, dust mulch, pusa hydrogel, stover mulch and pusa hydrogel + stover mulch and four zinc fertilization practices i.e. control, 2 kg Zn/ha, 4 kg Zn/ha and 6 kg Zn/ha. Result: The perusal of data clearly indicated that among moisture conservation practices, stover mulch proved significantly superior to control, dust mulch, pusa hydrogel with respect to higher in N, P, K and Zn content, their total uptake and protein content in pearlmillet but it was at par with pusa hydrogel + stover mulch. Under zinc fertilization treatments direct application of 6.0 and 4.0 kg Zn/ha being at par with each other and recorded significantly higher in nutrient content, protein content and total uptake of N, Zn and K over control.

“…Nevertheless, the importance of fertilizers, essential for achieving increased crop production, will further increase because there is little scope for bringing more areas under cultivation and majority of soils are deficient in many macroand micronutrients. It is now realized that in agricultural lands under intensive monoculture system, including rice, which receives heavy application of chemical fertilizers alone, productivity slowly is declining, and environmental quality is deteriorating [8]. Intensification of agriculture has also widened the gap between nutrient removal and supplies and, thus, soil fertility depletion [9].…”

At present time, chemical fertilizers are more in practice for crop production, which failed to upkeep soil and environment quality and affected the sustainability of the agricultural production system. Conversely, biofertilizers are ecosystem friendly, one of the best modern tools for agriculture, and are used to improve soil fertility and quality. Biofertilizers have now emerged as a highly potent alternative to inorganic fertilizers and offer an ecologically sound and economically attractive route for augmenting nutrient supply and increasing crop production. These include live cells of diverse genera of microorganisms and have the potential to fix atmospheric nitrogen and solubilize and mobilize plant nutrients from insoluble form through microbiological process. It has also the potential to diminish the gap between nutrient supply through fertilizers and nutrient removal by crops. Hence, biofertilizers can be a feasible option to the farmers to increase crop productivity and should find greater acceptance from the extension workers and commercial biofertilizer manufacturers.

The nitrogen-fixing bacteria work under two conditions, symbiotically (Rhizobium, Frankia) and as free-living bacteria (nonsymbiotic) such as Azotobacter and Azospirillum. The N 2 -fixing bacteria associated with nonlegumes include species of Achromobacter, The most exploited symbiotic N 2 -fixing bacteria are those belonging to the family Rhizobiaceae. Rhizobium inoculants are of greatest importance because of their ability to fix atmospheric N 2 in association with certain legumes [11]. It is estimated that N 2 fixation by Rhizobium in root nodules of legumes is of the order of 14 million tons on a global scale and is almost 15% of the industrial N fixation. Yield of many legumes can be increased substantially by the use of appropriate Rhizobium cultures. For successful nodulation each legume requires a specific species of Rhizobium to form effective nodules. Many legumes may be modulated by diverse strains of rhizobia, but growth is enhanced only when nodules are produced by effective strains of rhizobia [12]. Rhizobium can be used for legumes crop and trees (e.g., lucerne) and is a crop-specific inoculant, for example, Rhizobium trifolii for berseem, Rhizobium meliloti for lucerne, Rhizobium phaseoli for green gram and black gram, Rhizobium japonicum for soya bean, Rhizobium leguminosarum for pea and lentil, Rhizobium lupini for chickpea, and Rhizobium spp. for cowpea. Rhizobium is however limited by cross-inoculation group, and only certain legumes are benefited by this symbiosis.Similar to the Rhizobium, other filamentous bacteria of genus Frankia belonging to the family Frankiaceae are found in the root nodules of nonlegumes such as trees and shrubs. These bacteria live in symbiosis with actinorhizal plants. These actinorhiza...
