Impact of Nutrient Management on Soil Chemical Properties and Maize (Zea mays L.) Yield

The study in relation to “Impact of nutrient management on soil chemical properties and Maize (Zea mays L.) yield” was conducted during the year 2021-22 at Vizianagaram district of Andhra Pradesh. Application of optimal doses of inorganic and organic fertilizers to maize at 5 t FYM ha-1 yearly containing 126:58:45 NPK kg ha-1 and 17 kg Zn ha-1 with highest maize yield of 65.00 q ha-1 as compared to the farmers lower yield of 47 q ha-1 without the optimum dose of inorganic and organic fertilizers to maize. Soils of the study area were acidic to neutral in soil reaction, non-saline and non-calcareous in nature, low in organic carbon in both surface and sub-surface layers.

Impact of Nutrient Management on Wheat/Vegetable Yields and the Fate of 15N-Labeled Fertilizer in the Yangtze River Basin

The Yangtze River Basin (YRB) crosses three economic zones and major agricultural regions of eastern, central, and western China. Increasing non-point source pollution, caused by excessive nitrogen (N) inputs to farms, is one of the main causes of water contamination in the YRB. To improve N fertilizer use efficiency, we conducted a field experiment using 15N-labeled urea at three sites located in upstream, midstream, and downstream regions of the YRB to evaluate the impacts of improved fertilizer management on crop yield, fertilizer N recovery, and losses in three crop rotations: rice–wheat (RW), rice–vegetable (RV) [tuber mustard at Jiangjin (Chongqing), cabbage at Shayang (Hubei), and savoy cabbage at Rugao (Jiangsu)] and maize–wheat (MW). Applying only 50% of the traditional application of N and P fertilizer maintained the wheat yield at Jiangjin and Shayang and savoy cabbage yield at Rugao. However, it caused a 27% reduction of the wheat yield at Rugao. The 15N recovery showed that 27% of the fertilizer N was retained in the soil and that 25% less fertilizer N was lost to the environment compared to the traditional fertilizer application. Improved fertilizer management would reduce the environmental cost of farming in the YRB, but with some consequences to winter crop yields.

System productivity and economics as influenced by cropping system and nutrient management

A field experiment was conducted during kharif, rabi and summer 2013-16 at ICAR-IARI, New Delhi to study the effect of cropping systems and nutrient management on productivity of different crops and cropping systems, the impact of nutrient management on nutrient uptake in different crops and cropping systems and to evaluate economics of different cropping systems. Experiments were conducted in split-plot design replicated thrice. The treatments were comprised five cropping systems, i.e. pearl millet-wheat, pearl millet-mustard-cowpea, pearl millet-wheat-bottle gourd, clusterbean-mustard-cowpea, and clusterbean-wheat-bottle gourd and four nutrient management, i.e. control, RDN (recommended dose of nitrogen), 50% RDN + 50% N through FYM, and 50% RDN + 50% N through FYM + biofertilizers. All the recommended practices except treatment were adopted. The soil test value based nutrient application was done. Results revealed that maximum pearl millet equivalent yield (13.8 t/ha), production efficiency (37.8 kg/ha/day), rainfall-use efficiency (4.34 kg/ha-mm), net returns (₹89198) and benefit cost ratio (2.55) were found under the cropping system of pearl millet-mustard-cowpea. Total nitrogen uptake was obtained more under pearl millet-wheat-bottle gourd. The nutrient management practice of RDN gave higher pearl millet equivalent yield (13.5 t/ha), production efficiency (37 kg/ha/day), rainfall-use efficiency (4.25 kg/ha-mm), total N uptake (120.2 kg/ ha) and net returns (₹ 80243) but statistically at par with 50% RDN + 50% N-FYM + BF. The highest benefit cost ratio was recorded in 50% RDN + 50% N-FYM + BF (2.07). It is concluded that the cropping system of pearl milletmustard- cowpea with nutrient management practice of 50% RDN + 50% N-FYM + BF produced significantly higher yields and income.

Impact of nutrient management on yield and yield attributing traits of gerbera (Gerbera jamesonii L.) growing under protection

Gerbera is a flower of choice which is grown widely all across the world. Though quality accounts utmost importance beside quantity therefore feeding the plants with balanced combination and concentration of both major and micronutrients is a must. The present experiment entitled “Impact of nutrient management on yield and yield attributing traits of Gerbera (Gerbera jamesonii L.) growing under protection” was executed under polyhouse condition. This experiment was conducted following Randomised Block Design with three replications & twelve treatments including a control. Result of the investigation envisaged that the nutrient combination NPK 20:20:20 @15g/10 ltr + Multiplex General Liquid @0.2% (T12) performed best for the parameters like plant height (31.87 cm), leaf area (204.53 cm2), flower stalk length (46.50 cm), diameter of flowering head (10.84 cm), vase life of cut flowers (6.70 days) and chlorophyll content of leaves (73.02). However, the plants treated with NPK 20:20:20 @15g/10 ltr + Power Bio-20 @0.2% (T11) exhibited significant increase in parameters like number of leaves per plant (37.67), number of suckers per plant (3.20), flower stalk diameter (5.70 mm) and flower neck diameter (3.45mm). On the other hand, the nutrient combination NPK 20:20:20 @15g/10 ltr + ZnSO4 @0.2% + MnSO4 @0.2% (T6) resulted in maximum plant spread (54.53 cm) and number of flowers per plant (3.63).

Impact of nutrient management on performance of rice (Oryza sativa) – blackgram (Vigna mungo L.) cropping system

A field experiment was conducted at ICAR – Indian Institute of Rice Research Hyderabad during kharif and rabi seasons 2010 – 2011 and 2011 - 2012 to study the effect of sulphur on yield, nutrient status in grain and economics in rice – black gram cropping system. The experiment consisted of different levels of fertilizer (M1 - 120:60:40; and M2 - 60:30:20 kg N, P2O5 and K2O/ha) and sulphur schedules (S1 - control, S2 - sulphur application @ 30 kg/ha during kharif only, S3 - sulphur application during rabi only and S4 - sulphur application during both kharif and rabi) were evaluated with variety Jaya during kharif and blackgram variety LBG-648 during rabi season to study the applied, residual and cumulative effects of sulphur (S) in rice under selected rice based cropping systems in relation to improvement of productivity. Pooled results indicated that maximum rice yield (5.64 tonnes / ha) recorded in M2S3 (60:30:20 kg N P2O5 and K2O/ha + Sulphur application @ 30 kg/ha during rabi only) treatment where as corresponding minimum rice yield (3.71 tonnes / ha) was recorded with control (M1S1) where no application of sulphur was done. Similarly maximum black gram seed yield (1.98 tonnes / ha) was recorded in M2S3 where as corresponding minimum black gram yield (0.87 tonnes / ha) was recorded in control (M1S1) (120:60:40 kg N, P2O5 and K2O/ha + control). Highest nutrient composition of sulphur content, N content, protein content, P content and K content in paddy and black gram seed was recorded when sulphur was applied in rabi season (S3). Highest Zn content in Paddy seed (13.50 ppm) was obtained when sulphur was applied in kharif season (S2) and in black gram (77.67 %) when sulphur was applied in kharif and rabi season (S4).

Studies on impact of nutrient management and tillage practices on yield attributes and yield on gram – maize cropping sequence

Awareness to wards soil health and food quality has forced to find out a suitable and eco-friendly nutrient management system of crop production. Integrated nutrient management system found suitable on yield of cereal crops, but has least impact on leguminous crops. To study the impact of nutrient management practices and tillage practices was studied at the farm of Department of Soil Science, CSKHPKV, Palampur during 2013-16 gram-maize cropping sequence. The organic management with conventional tillage was found to be significantly superior with rest of the treatment combinations on yield attributes, symbiotic parameters and yield of gram in all the three years. The major constraints to grow gram at Palampur was the attack of root rot disease. The disease incidence was reduced through organic nutrient management with conventional tillage. The yield attributes and yield of maize was better in integrated management in organic management in second year. The conventional tillage in both the years registered significant impact on yield and yield attributes of maize.

Impact of nutrient management, soil type and location on the accumulation of capsaicin in Capsicum chinense (Jacq.): One of the hottest chili in the world

Capsicum chinense (Jacq.) cv. Borbhut a highly pungent and strictly endemic landrace is found in Northeast India. Information regarding scientific cultivation of this crop is not available. In the present investigation, we formulated a few organic based integrated nutrient management schemes to standardize the pungency and hotness of the crop in two widely apart locations. Here we assess the impact of the management schemes on capsaicin accumulation in C. chinense grown in two types of soil (alluvial and lateritic) falling in two states of India (Assam and West Bengal). Some vital nutritional (crude protein, fibre, sugar and acid contents) and phytochemical features (β-carotene, lycopene) were also evaluated. Chilies grown in Assam soil (alluvial) exhibited significantly higher capsaicin content and pungency than those grown in the West Bengal soil. Application of vermicompost alone resulted in higher fruit yield, soluble sugar, protein, fibre, and lycopene contents in plants of Assam; whereas in West Bengal the maximum fruit yield and nutritional attributes were observed in plants grown under NPK+Vermicompost. However, vermicompost based nutrient management scheme efficiently elevated the pungency level in “Borbhut” irrespective of soil types.

Impact of Nutrient Management and Agro-forestry Systems on Growth and Yield of Sunflower

A field experiment was conducted to evaluate the effect of integrated nutrient management (INM) practices on growth, yield parameters and yield of sunflower grown under neem (Azadirachta indica) and melia (Melia azadirach) trees during kharif 2009 at Student's Farm, College of Agriculture, Hyderabad. Dry matter production, crop growth rate, leaf area index, yield components and yield of sunflower was higher in sole cropping of sunflower compared to sunflower grown under neem or melia trees. Higher sunflower yield was recorded under sole cropping (560 kg /ha) compared to sunflower grown under neem and melia trees with yields of 461 and 317 kg /ha respectively. Application of subabul (Leucaena leucocephala) green leaf manure at 5 t / ha + 30 kg N/ha produced more growth, yield parameters, and yield of sunflower compared to other nutrient management practices. The studies suggested that sunflower was compatible with neem trees. However, melia trees had severe impact on growth, yield and yield parameters. Application of green leaf manure with half of recommended dose of nitrogen recorded better yield than recommended dose of nitrogen alone.
