A field experiment was conducted in the experimental farm of Zonal Agricultural Research Station, Dumka, Birsa Agricultural University, Ranchi, Jharkhand during kharif seasons of 2015, 2016 and 2017 to study the effects of secondary and micronutrients on rice under rice-wheat cropping system in acid soil. The experimental findings have been interpreted in terms of grain yield, crop response (%), P, K, S and B -uptake by the crop. There were seven treatment combinations viz., NPK (RD) [@ (80 : 40 : 20) kg / ha], NPK + FYM [@ 3t / ha], NPK + lime [@ 4q / ha], NPK + S [@ 30kg / ha], NPK + S + B [@ 200 ppm foliar spray as borax], NPK + S + B + Si [@ 20 kg K - silicate / ha] and (NPK + FYM + S + B + Si). The experiment was laid out in RBD with three replications. It was found that the highest grain yield (40.60 q / ha) was obtained with the combined application of (NPK + FYM + S + B + Si), which also corresponded to the maximum crop response (24.4%). It was also found that application of micronutrients alone did not have significant effects on S and B-uptakes unless they were applied in combination with FYM. The highest S-uptake (7.40 kg/ha) and B-uptake (126.03 g/ha) were recorded with (NPK + FYM + S + B + Si). The highest P-uptake (13.74 kg/ha) and K-uptake (16.11 kg/ha) were obtained with (NPK + Lime).

Abstract. The adoption of Conservation agriculture (CA) contributes to sustainable production and its advantages include lower inputs and stable yields. This study was conducted in the research field of Regional Agricultural Research Station, Bhagetada, Dipayal, Doti during 2014 and 2015 to identify the effect of CA on grain yield and income of maize in Maize based cropping system. Both conservation and conventional agricultural (ConvA) practices were evaluated on two maize based cropping systems namely maize-wheat-mungbean (M-W-MB) and maize-lentil-mungbean (M-L-MB). For this purpose two maize varieties namely Raj Kumar and Arun-2 were used. The average productivity of maize under M-L-MB cropping system was 1.6% higher (5.75 t/ha) than M-W-MB cropping system (5.66 t/ha). The average grain yield of maize under CA was 16.7% higher (6.15 t/ha) than ConvA (5.27 t/ha). Rajkumar produced 43% higher average grain yield (6.73 t/ha) than Arun-2 variety (4.69 t/ha). The average net benefit was slightly higher (US$ 597.33/ha) under M-L-MB cropping system than M-W-MB cropping system (US$ 573.89/ha). Similarly, the average net benefit from CA was 102% higher (US$ 783.67/ha) than ConvA (US$ 386.79/ha). Rajkumar variety gave 127% higher average net benefit (US$ 813.49/ha) than Arun-2 (US$ 357.81/ha). The average benefit - cost (B:C) ratio of M-L-MB cropping system was slightly higher (1.72) than the average B:C ratio of M-W-MB cropping system (1.70). The average B:C ratio of CA was 42% higher (2.01) than ConvA (1.41). The average B:C ratio of Rajkumar variety was found 33% higher (1.95) than Arun-2 (1.46). The higher grain yield, net profit and B:C ratio were found in CA practices under M-L-MB cropping system and Rajkumar variety. This study suggests that hybrid maize planting and the adoption of M-L-MB cropping system should be used to increase grain yield and economic performance under CA practices.

Field experiments were conducted at the Agricultural Research Station, Bhavanisagar, Tamil Nadu, India during 1999 to 2000 in Inceptisols to evaluate boron fertilizers (borax, boric acid, Agribor) and to assess the effect of the mode and level of B application on the total B uptake and yield of sunflower and green gram. The experimental field was found to be deficient in available B (0.35 mg kg-1). Sunflower was raised as the main crop. Different B levels (0.5, 1.0, 1.5and 2.0 kg B ha-1)as soil application and two levels of foliar spray (0.2% and 0.3%) were compared with the control. The treatments were superimposed on the recommended dose of NPK. After harvestingthe main crop of sunflower, the residual effect of B was studied by raising green gram on the same field. The results revealed that the application of all the levels of B resulted in a significant increase in the B uptake and yield of sunflower as compared to the control. The highest yield was recorded for the soil application of B at a rate of 2.0 kg ha-1. The yield increase of sunflower was 3.6 to 15.8% and 7.2 to 18.9% over the control for seed and stalk, respectively. The green gram grain yield increased by 4.2 to 13.5% after the application of 1.0 and 2.0 kg B ha-1 to the main crop. No residual effect was observed for the lowest level of B application (0.5 kg ha-1). Agribor is equally as effective as borax in influencing the B nutrition of both the crops.

The influence of graded levels of phosphorus at different fertility gradient on soil properties was studied at Zonal Agricultural Research Station (ZARS), GKVK, UAS, Bengaluru under finger millet-maize cropping system. Five phosphorus fertility gradients viz., P0 (Very low), P1 (Low), P2 (Medium), P3 (High) and P4 (Very high) (< 15, 16-30, 31-45, 46-60 and > 60 kg P2O5 ha-1) were imposed. Results indicated that, availability of N, P, K, S, Mg, Mn, Cu content was higher in very high fertility strip, whereas the exchangeable Ca, DTPA-Fe and Zn were significantly higher in medium P fertility gradient strip. Combined application of manures and fertilizers resulted in relatively higher availability of nutrients as compared to inorganics alone. Further, there was a build-up of P in gradient strips with graded levels of P application.

Field experiments were conducted during kharif 2013 and 2014 at Agricultural Research Station, Mugad, University of Agricultural Sciences (UAS), Dharwad (Karnataka), to determine the response of zinc applicationon on growth, zinc content and grain yield of rice genotypes and also studied correlation between yield and zinc content. The experiment was comprised of 20 genotypes and three treatments viz., T1: Control (no zinc); T2: Soil application of ZnSO4 (20 kg ha-1) T3– Foliar Spray of ZnSO4 @ 0.5% at 50% flowering, laid out in factorial randomized block design with two replications. The data revealed that application of ZnSO4 recorded significantly higher plant height (85.9 cm), leaf area (764.5 cm-2 plant-1), number of tillers (95.4 m-1), total dry weight (26.1 g plant-1), panicle weight(15.3 g plant-1), number of panicles (81.6 m-1) and grain yield(3966 kg ha-1) over the foliar application of Zn and control . However number of grains panicle-1 (97.8 panicle-1), test weight (23.7 g), shoot and seed zinc content (15.9 and 21.2 ppm, respectively) were increased with foliar application of Zn. Correlation studies classified the genotypes as high seed zinc content (> 21 ppm) and low seed zinc content genotypes ( less than 21 ppm). High and low seed zinc content genotypes showed negative correlation with yield and yield attributes. However, shoot zinc content was positively correlated with yield.

Aims: To find a suitable alternate option of nutrient management in organic mungbean with standardization of dose and its mode of application. Place and Duration of Study: Agricultural Research Station, Mandor, Jodhpur between July 2020 and October, 2020. Methodology: Treatment comprised of main plots as mode of application: M1: Soil application, M2: Foliar application and M3: Soil and foliar application and sub plots as dose of Jiwamrita: S1: Control, S2: 50 ml/l, S3: 100 ml/l and S4: 150 ml/l were replicated thrice in split plot design. FYM @ 5.0 t/ha was applied on the soil and the field of the experimental site was prepared by disking following harrowing and planking. The crop variety GM 6 was sown on 10th July, 2020 at row spacing of 30 cm with seed rate of 15 kg/ha. The plants were kept at 10 cm distance after thinning at 15 days after sowing. Jiwamrita was prepared using Palekar [1] method (Photo 1) and was kept in shade for 7 days. It was filtered before using for spray as per treatments. It was applied as soil spray at the time of sowing and 15 days after sowing as per treatments of different doses. Foliar application of Jiwamrita was done at 15 and 30 days after sowing as per treatments. Total quantity of solution containing Jiwamrita was 500 liter/ha in all the treated plots. In control plots, a quantity of 500 liter/ha was used as spray. Weeding was done manually at 15 and 30 days after sowing. Data on growth attributes, yield attributes and grain yield was recorded from net plot size of 4 m x 1.8 m and converted into hectare basis. The gross return was computed by multiplying current price of mungbean with yield. The net return was estimated by deducting cost of cultivation from gross return. The benefit-cost ratio was worked out by dividing gross return by cost of cultivation. Results: Maximum plant height of 71.5 cm was recorded with a dose of Jiwamrita @ 150 ml/liter which was at par with Jiwamrita @ 100 ml/liter. The SPAD chlorophyll meter reading (SCMR) of leaves increased at 50 DAS (53.5) being maximum with Jiwamrita @ 150 ml/liter which was significantly higher over SCMR recorded with Jiwamrita @ 50 ml/liter (34.7). The significantly maximum number of pods/plant (28.7) and maximum grain yield (1314 kg/ha) was recorded due to combined application of soil and foliar application of Jiwamrita. Among doses, maximum number of pods (30.9) was recorded under Jiwamrita @ 150 ml/liter which was 30, 24 and 16 percent higher over control and Jiwamrita @ 50, 100 ml/liter. The application of Jiwamrita @ 150 ml/liter resulted in significantly higher grain yield (1221 kg/ha) which was found at par with Jiwamrita @ 100 ml/liter (1179 kg/ha) which were 17 and 13 percent higher, respectively, over control and 9 and 5.6 percent higher, respectively, over Jiwamrita @ 50 ml/liter. The maximum net return ( 65672 ha-1) was recorded with 150 ml/liter followed by 100 ml/liter ( 62686 ha-1). Conclusion: Jiwamrita is a fermented microbial culture which provides essential nutrients to plants. Its application in both soil and plant canopy were found beneficial. The study revealed that twice application of Jiwamrita in soil at the time of sowing and 15 days after sowing and twice application of Jiwamrita as foliar spray at 15 and 30 days after sowing significantly increased the growth attributes, yield attributes and yield of organic mungbean.

Residue Retention

Zero tillage with crop residue retention which is principle of conservation agriculture (CA) can be a good practice to achieve sustainable and profitable crop yield without affecting soil fertility. This approach was not tested in wheat and lentil based maize-mungbean system in far western Nepal. The effect of CA in the maize-wheat-mungbean and maize-lentil-mungbean cropping systems with two varieties of each of wheat and lentil was studied at Regional Agricultural Research Station, Bhagetada, Dipayal, Doti district of Nepal for two years (2015 and 2016).  The average grain yield of wheat and lentil under the CA system was 5.92% higher (2.86 t ha−1) than that of conventional agriculture (2.70 t ha−1). The CA under maize-wheat-mungbean cropping system produced 7.90% higher grain yield (4.78 t ha−1) compared to conventional agriculture and the CA under maize-lentil-mung bean cropping system gave11.11% higher grain yield (1.00 t ha−1). Maize-wheat-mungbean cropping system, conservation agriculture and WK 1204 variety of wheat produced 9.34% higher yield (4.80 t ha−1) than conventional agriculture whereas maize-lentil-mungbean cropping system, conservation agriculture and Khajura1 variety of lentil recorded 11.96% higher grain yield (1.03 t ha−1) than conventional agricultural. The CA system produced 114% higher net benefit (NRs. 40200 ha−1) than that of conventional agriculture. Higher yields of crops in CA system could be associated with improvement of soil properties for minimum soil disturbance and residue retention and profitable yield for reduced cost of production. Thus, the 2-year study suggests that no tillage with previous crop residues retention and use of higher yielding varieties is a potential crop cultivation approach for the maize based cropping system in light textured soil of river basin area of Nepal in order to sustain soil health, crop yield and farm economy.

Two pots experiments were conducted at the Experimental Farm of El-Qassasin Horticultural Research Station, Agricultural Research Center, Ismailia Governorate, Egypt, during two successive seasons of 2016/2017 – 2017/2018, to investigate the effect of potassium silicate at (0, 4, 6, and 8 cm3/l) as a foliar spray under different levels of water salinity (tap water, 1000, 2000 and 3000 ppm) on Calendula officinalis L. plant. The experiment was performed in complete randomized block design as factorial experiment with 3 replicates. The obtained results cleared that using salinity levels decreased growth parameters (plant height, number of branches/plant, fresh and dry weights of herb/plant), flowering parameters (flower diameter, number of flowers/plant, fresh and dry weight of flowers (g/plant) during eight cuts and fresh and dry weight of flowers (g/plant/season)) and chemical constituents (chlorophyll a, chlorophyll b, carbohydrate and carotenoid contents) compared to control. Moreover, the highest values in these parameters were registered by potassium silicate at 8 cm3/l concentration. Proline content increased in leaves with using saline water at 3000 ppm + potassium silicate at 8 cm3/l. Generally, it could be concluded that potassium silicate at 8 cm3/l, showed a uniform impact in alleviating inhibition of Calendula officinallis L. plant growth and productivity under moderate salinity stress condition.

To estimate genetic parameters and heritability in durum wheat (Triticum turgidum var. durum) genotypes, seventeen genotypes (16 exotic from ICARDA and local variety (Buhooth 7)) were included in this study. This experiment was conducted using a randomized complete block design with three replications at Field Crops Research Station, Abu-Graib, Office of Agricultural Research, during 2011-2012 and 2012-2013. The results revealed significant differences among genotypes for the studied characters at both seasons. The best genetic/environmental variance ratio attained for spike length (11.90) and no. of spikes. m-2 (9.22) in the first season, and grain yield (8.82) then harvest index (4.87) in the second season. High GCV observed for grain yield (15.68), no. of spikes. m-2 (15.18) in the first season, and harvest index (16.89) and grain yield (14.22) in the second season. High heritability estimates associated with high genetic advance for no. of spikes. m-2, in the first season. While, moderate h2bs estimates associated with high GA for same trait in the second season. Expected response to selection ranged from 0.93 to 84.6, also selection index ranged from 1.23 to 106.44 for grain yield and number of spikes. m-2, respectively in the first season also the same pattern was observed for value of second season. Characteristics like no. of spikes. m-2, plant height, no. of grains. Spike-1 and grain weight showed high heritability coupled with high genetic progress. Therefore, these characters should be given top priority during selection breeding in durum wheat.

Coordinated Varietal Trial (CVT) and Advanced Varietal Trial (AVT) of wheat were conducted at Regional Agricultural Research Station,Doti during the year 2012 and 2013. Microplot Yield Trial (MPYT) were conducted during the year 2013. Total 20 genotypes were includedin CVT experiment of both years. Although the difference in grain yield due to genotypes was not found significant during the year 2012, NL1144 recorded the highest grain yield (4309 kg/ha) followed by NL 1140 (4295 kg/ha) and NL 1147 (4165 kg/ha) respectively. But in the year2013, NL 1097 produced the highest grain yield (4641 kg/ha) followed by NL 1135 (4383 kg/ha) and NL 1164 (4283 kg/ha) respectively.Statistically, the difference in grain yield due to genotypes was not found significant in the year 2013. Combined analysis over years was alsocarried out. Out of 20, only 10 genotypes were included in the CVT experiment, which were found similar in both years. Genotypes NL 1097(4079 kg/ha), NL 1140 (3814 kg/ha) and NL 1093 (3773 kg/ha) were found high yielding genotypes for river basin agro-environment of farwestern hills. Statistically, effect of year in tested characters was found significant whereas treatment effect was observed non-significant.Similarly, 20 genotypes of wheat were included in AVT of wheat during the year 2012 and 2013. Out of the genotypes included in AVT duringthe year 2012, KISKADEE No.1recorded the highest grain yield (3824 kg/ha) followed by CHEWINK No. 1 (3643 kg/ha) and WK 2120 (3583kg/ha). Statistically all the tested characters except grain yield were found significantly different due to genotypes. But in the same experimentof the year 2013, WK 2412 genotype recorded the highest grain yield (4407 kg/ha) followed by WK 2411 (4329 kg/ha) and Munal-1 (4054kg/ha). Statistically the difference in grain yield and other tested characters were found significantly different. Due to dissimilarity in the testedgenotypes we could not carry-out the combined analysis over years. Total 30 genotypes were included in the MPYT experiment of the year2013. Genotype WK 2272 recorded the highest grain yield (6080 kg/ha) followed by the genotypes WK 2274 (5152 kg/ha) and WK 2278(4480 kg/ha) respectively. Statistically, the difference in grain yield and other tested characters were found significantly different due togenotypes.Int J Appl Sci Biotechnol, Vol 3(3): 417-422
