Present study aimed to evaluate the production potential of cape gooseberry (Physalis peruviana L.) in sodic soil (pH 8.56) under varying plant spacing and soil fertility levels. The spacing treatments were S1-75 x 60 cm, S2-75 x 75 cm and S3-90 x 75 cm, while native soil fertility was manipulated through the application of NPK fertilizers i.e. F0-control (no NPK fertilizers), F1 - 60:40:40, F2 - 80:60:60, and F3 - 100:80:80 kg NPK ha-1. Two year’s data from the study revealed that spacing and NPK treatment had significant effect on vegetative growth and fruit yield during both the years. Closest spacing (75 x 60 cm) resulted tallest plants (103.41 and 100.35 cm) and maximum fruit yield (86.69 and 83.56 q ha-1), but this treatment was statistically at par with 75 x 75 cm spacing. Widest spacing (90 x 75cm) resulted maximum number of branches (34.14 and 32.49 plant-1), number of leaves (167.31 and 162.70 plant-1) and average fruit weight (9.26 and 9.18 g), but was statistically at par with 75 x 75 cm spacing. Amongst the fertilizer treatments, application of NPK @100:80:80 kg ha-1 resulted maximum plant height (114.88 and 11.65 cm), number of branches (35.78 and 34.82 plant-1), number of leaves (174.82 and 172.55 plant-1), fruit weight (9.62 and 9.57 g) and fruit yield (101.08 and 98.08 q ha-1). Biochemical quality of fruits (TSS, ascorbic acid, acidity, and reducing, non-reducing and total sugars) was increased due to increased fertility level and recorded maximum with the application of 100:80:80 kg NPK ha-1. These findings will be helpful in exploring cape gooseberry cultivation in sodic soils (pH 8.56) through suitable agronomic manipulations in plant spacing and soil fertility levels.

Sorghum and wheat are the premier food grain crops of the peninsular central India and in particular of Maharashtra. There has been a phenomenal increase in its production after mid sixties with the introduction of high yielding varieties. Increase in production was achieved through increase in area as well as productivity. Inputs like improved seeds, irrigation, fertilizers etc. has given a boost to productivity. Continuous addition of chemical fertilizers poses problems like toxicity due to high amounts of salts as residues of fertilizer and deterioration of the physico-chemical properties. Organic manure ameliorates this problem as organic matter helps in increasing adsorptive power of soil for cations and anions particularly phosphate and nitrate. Long term manuring and fertilizer experiments conducted in India showed declining trend in productivity even with the application of NPK fertilizers under modern intensive farming. Neither organic source alone nor inorganic fertilizers can achieve sustainability in crop production under intensive agriculture, where nutrient turnover in soil-plant system is much higher. However, their combined use appeared promising in enhanced crop productivity besides improving soil fertility.

A balanced application of organics and inorganic fertilisers could be beneficial to both soil nutrient availability, soil health and crop growth. The experiment was conducted on light textured highly calcareous soil at Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa. Four levels of inorganic fertiliser treatments were applied i.e. 50, 100 and 150% of NPK along with no NPK as control as main plot treatments while four levels of organic treatment (i.e. no organics, compost, crop residue and compost+ crop residue) were applied as sub plot treatments in a split plot design with a total sixteen (16) treatments with three replications to investigate the long term effect of application of various doses of recommended fertiliser along with organic amendments on various physico-chemical properties of calcareous soils after 32nd crop cycle . Data was collected on various physico-chemical properties i.e. Soil pH, electrical conductivity (dSm-1), soil organic carbon (g kg-1), free CaCO3 (%), cation exchange capacity [cmol (p+) kg -1], bulk Density (Mg m-3) and water holding capacity (w/w %). The result revealed that soil pH was reduced by 3.9% while electrical conductivity (EC) was reduced by 45% over initial (1988). Both soil pH and EC were reduced by 1.7% and 15.4% respectively in plots receiving combined application of compost and crop residue along with 150% NPK over control. Organic carbon was improves by 33% over initial (1988) which had direct effect on reduction in soil bulk density (32%) and improved water holding capacity (29%) over the control in plots receiving 150% NPK along with combined application of compost and crop residue. Soil cation exchange capacity and free CaCO3 also showed an alternate trend former being enhanced and later being reduced after 32nd crop cycle in rice-wheat cropping system. Application of different levels of NPK along with different organics improved the overall soil physico-chemical properties which further have direct relation with enhanced crop growth and productivity.

Imbalanced use of nutrients through fertilizer have a deleterious effects on soil health, leading to unsustainable productivity. The present investigation was carried out to study the comparative effectiveness of compost and crop residue either alone or in combination of chemical fertilizer on physico chemical properties of soil, soil microbial biomass and crop yield in rice-wheat cropping system in Calciorthents at experimental farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar in light texture and medium fertile soil. There were sixteen treatments which were replicated thrice in split plot design. Four level of NPK viz., no NPK, 50% NPK, 100% NPK and 150% NPK were kept as main plot treatments whereas four levels of organics viz., no manure, compost @ 10 t ha-1, crop residue and compost + crop residue were treated as sub-plot treatments. The correlation between rice yield and some physico-chemical and microbial attributes of soil were evaluated. Most of soil physical, chemical and microbiological parameters were positively correlated with grain and straw yield of rice. Thus the results suggest that integrated use of balanced inorganic fertilizers in combination with organic manure sustains a soil physico-chemical and microbiological environment of soil that is better for enhancing higher crop productivity.

By nature coastal saline soils having several constraints in crop production in addition to that of heavy metals contamination deteriorate the soil productivity. To restore these contaminated soils, various remediation techniques in practices must be revamped. The present study was conducted to enhance the accumulation of heavy metals lead and cadmium in sunflower and improve the crop productivity using organic and inorganic soil amendments along with NPK fertilizers in completely randomized design. Soil samples were admitted to estimating soil physico chemical properties and DTPA extractable lead (Pb) and cadmium (Cd) and plant samples analyzed for DTPA extractable Pb and Cd concentrations under ICP-OES. The physico-chemical properties and DTPA extractable Pb and Cd concentrations were significantly influenced by amendments. Sunflower exhibited significant differences concerning accumulation of Pb and Cd against amendments tested along with higher biomass production. Higher shoot and root concentration of Pb(0.72,0.81 and 0.94,0.97 mg kg-1) and Cd (1.78, 2.32 and 0.35,0.32 mg kg-1)were recorded in the treatment RDF + EDTA, which was followed by RDF + Potassium humate and RDF + Zeolite application at 45 DAS and at harvest. Remediation efficiency of sunflower increased by application of RDF + EDTA through enhanced solubility of Pb and Cd in soil and thus increased Pb and Cd accumulation in root and shoot of sunflower. Whereas, the application of RDF+ FYM or press mud reduced the bioavailability of Pb and Cd in soil and thus restricted the accumulation of Pb and Cd by sunflower. Further, application of NPK fertilizers maintained the availability of nutrients and enhanced the yield of sunflower. The application of EDTA along with NPK fertilizer enhanced the bioaccumulation of lead and cadmium by sunflower without yield loss. Since, there is a possibility to cause leaching of HMs to ground water by EDTA. Hence, RDF plus Potassium humate or Zeolite can be recommended for lead and cadmium removal by sunflower in coastal saline soils with no loss in crop productivity.

This study investigated the energy input-output relationship in biomass production of cape gooseberry (Physalis peruviana L.) grown in Sodic soils of Indo-Gangetic plains with agronomic manipulations of plant spacing (90 x 75 cm, 75 x 75 cm, 75 x 75 cm) and NPK fertilizers (0, 60:40:40, 80:60:60, 100:80:80 N:P2O5:K2O kg ha-1). Results indicated that total input energy requirements in various treatments ranged from 16784.72 MJ ha-1 in 90 x 75 cm spacing without NPK fertilizers to 24395.04 MJ ha-1 in case of 75 x 60 cm spacing with NPK  at 100:80:80 kg ha-1. Irrespective of agronomic manipulations, share of non-renewable energy in total input energy was very high (64.56%) and the percentage proportions of direct and indirect energies in the total input energy were 75.56 and 24.13%, respectively. Among various inputs, diesel accounted for the greatest proportion (40.44%) of total input energy, followed by water (32%), fertilizers (19.28%) and these three inputs constituted 92.08% of total input energy. Crop raised at 75 x 60 cm spacing with NPK at 100:80:80 kg ha-1 resulted the highest output energy (80863 MJ ha-1), net energy return (56529.91 MJ ha-1) and energy use efficiency (3.22); however, the results obtained at 75 x 60 cm spacing with NPK at 100:80:80 kg ha-1 were comparable. The best energy productivity (0.43) was achieved with 75 x 75 cm spacing and 100:80:80 kg NPK ha-1.

Vegetative and reproductive growth in cape gooseberry (Physalisperuviana L.) proceed concomitantly during the greater part of the life cycle thereby foliar traits (e.g. leaf area) become important in photosynthetic action of the plant. In present study, the leaf area variation in cape gooseberry was studied at five phenological stages i.e. pre-flowering (30 DAT), start of flowering (60 DAT), early fruiting (120 DAT), peak fruiting (180 DAT) and late fruiting (240 DAT), grown at three spacings (60 × 75, 75 × 75 and 75 × 90 cm) and four NPK levels (control, 60:40:40, 80:60:60 and 100:80:80 kg ha-1). Leaf area increased from per-flowering (73.51 cm2) to start of flowering (82.26 cm2) and thereafter, it was decreased gradually at later stages i.e. early fruiting (79.17 cm2), peak fruiting (73.15 cm2) and late fruiting (60.21 cm2). Spacing had no significant effect on leaf area at pre-flowering and start of the flowering, but at later stages, widest spacing (75 × 90 cm) exhibited significantly maximum leaf area at early fruiting (82.44 cm2), peak fruiting (78.22 cm2) and late and fruiting (65.31 cm2). Leaf area increased due to increased NPK levels with maximum values under 100:80:80 kg NPK ha-1 at all the phenological stages: pre-flowering (78.99 cm2), start of flowering (90.97 cm2), early fruiting (88.47 cm2), peak fruiting (80.74 cm2) and late fruiting (67.22 cm2). Spacing × NPK Interactions was significant only at peak fruiting and late fruiting stages with maximum leaf area (75.22 and 71.02 cm2, respectively) at 75 × 90 cm + NPK @ 100:80:80 kg ha-1. These findings can be further helpful in leaf sclerophylly studies in cape gooseberry.
