The present experiment was conducted to study the response of naphthalene acetic acid NAA and integrated nutrient management on yield and yield attributes as well as and economics of chilli (Capsicum annuum L.) with four levels of NAA (0 ppm, 25 ppm, 50 ppm and 75 ppm) and five levels of vermicompost (VC) along with RDF (V0-100% Recommended dose of fertilizer i.e. 120:60:60 Kg N P K /ha ), V1-100% N through Vermicompost, V2-75% N through VC + 25% (RDF), V3-50% N through VC + 50% (RDF) , V4-25% N through VC + 75% (RDF), having 20 treatment combinations. The results revealed that the combine application of 50 ppm NAA and 100% N through vermicomposti.e. P2V1 performed well in respect of fruit length (8.73 cm), fruit diameter (1.46 cm) and fruit weight (2.91 g) while the application of NAA 50 ppm + 50% N through vermicompost along with 50% RDF i.e. P2V3 gave significantly (P=0.05) maximum number of fruits/plant (73.86) and fruit yield per hectare (121.20 q) with higher gross income (Rs.2,66,640.00/ ha), net profit (Rs.1,98,946.00/ ha) and benefit - cost ratio (2.94). Therefore, it can be concluded that the combine effect of NAA 50 ppm along with 50 % N through vermicompost +50% inorganic fertilizers (RDF) gave better result regarding growth and yield attributes and also generated maximum gross income, net return and B:C ratio while the next best treatment was application of NAA 75 ppm along with 25 % N through vermicompost + 75 % inorganic fertilizers (RDF).

A field experiment was conducted during rabi season of 2011-12 on heavy black soil to study the effect of integrated nutrient management on growth and yield of baby corn. The treatments comprising all possible combinations of five levels of nitrogen (chemical and vermicompost fertilizer) with and without bio-fertilizer (Azotobacter and PSB) were laid out in randomized block design with three replications. These were significantly higher with application of 100% RDN from chemical fertilizer with bio-fertilizer over 100% RDN from vermicompost. The cob and fodder yields significantly differed with different integrated nutrient management treatment. Significantly the higher growth and yield attributes yield and fodder yield were recorded with the application of 100% RDF from chemical fertilizer with bio-fertilizer. Application of 100% RDN from chemical fertilizer with biofertilizer was recorded higher net returns over 100% RDN from vermicompost (Rs. 220775/ha) and BCR (12.54).

For sustainable boro rice production in Bangladesh, a balanced fertilization to improve the current soil condition caused by mono-application of inorganic fertilizers and appropriate rice variety selection are very crucial. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during the boro season of December 2016 to May 2017 to evaluate the effect of integrated nutrient management on two boro rice cultivars. The varieties were BRRI dhan28 and BRRI dhan29 and eight kinds of nutrient management viz., control (no fertilizers), recommended dose of inorganic fertilizers (120-60-40 N, P2O5, K2O kg ha-1 + gypsum 60 kg ha-1 and ZnSO4 @ 10 kg ha-1), full dose of poultry manure @ 5 t ha-1, cowdung @ 10 t ha-1, poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of other inorganic fertilizers, cowdung @ 5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers, poultry manure @ 2.5 t ha-1 + 75% prilled urea and full dose of inorganic fertilizers, and cowdung @ 5 t ha-1 + 75% prilled urea and full dose of other inorganic fertilizers. The experiment was laid out in a split plot design with three replications. Result showed that, yield and yield components of boro rice were significantly influenced by variety, nutrient management and interaction of variety and nutrient management. In respect of grain yield, BRRI dhan29 produced the maximum yield (5.46 t ha-1). BRRI dhan28 showed poor performance with all characters and gave the minimum yield (4.07 t ha-1). In case of nutrient managements, the highest yield and yield component were obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers and produced the maximum grain yield (5.70 t ha-1). In the interaction of variety and integrated nutrient management, the highest grain yield (6.83 t ha-1) and straw yield (7.61 t ha-1) was obtained from poultry manure @ 2.5 t ha-1 + 50% prilled urea and full dose of inorganic fertilizers with BRRI dhan29 variety. So, BRRI dhan29 with 2.5 t ha-1 poultry manure + 50% prilled urea and full dose of the recommended inorganic fertilizers might be a promising practice for boro rice cultivation.

Background: An experiment on “Effect of Integrated Nutrient Management on Growth, Yield Attributes and Economics of Spiny Brinjal (Solanum melongina L.) var. VRM (Br)-1” were conducted at Adhiparasakthi Agricultural College farm, Vellore District, Tamil Nadu. Methods: Eleven treatments of integrated nutrient management viz., T1-RDF of N:P:K (100:50:30 kg/ha.), T2– FYM (25 t/ ha.), T3- Humic acid (20 kg/ha.), T4- RDF of N:P:K (100:50:30 kg/ha.) +FYM @25 t/ ha, T5- Humic acid (20 kg/ha.) + RDF of N:P:K (100:50:30 kg/ha.), T6- Azospirillum (2 kg/ha.), T7- Phosphobacteria (2 kg/ha.), T8- Azospirillum (2 kg/ha.) + Phosphobacteria (2 kg/ha.), T9 – 75% RDF of N (75 kg/ha.) + 100% RDF of P&K (50:30 kg/ha.) + Azospirillum (2 kg/ha.), T10 - 75% RDF of P (37.5 kg/ha.) + 100% RDF of N&K (100:30 kg/ha.) + Phosphobacteria (2 kg/ha.) and T11 - 75% RDF of N & P (75:37.5 kg/ha.) + 100% RDF of K (30 kg/ha.) + Azospirillum (2 kg/ha.) + Phosphobacteria (kg/ha.) replicated thrice in Randomised block design. Results: The various treatments of integrated nutrient managementin spiny brinjalclearly showed that growth and yield attributes were high in T11.The economic assessment of different treatments revealed that maximum net profit Rs.2,16,570/ha.with benefit cost ratio (2.60) was also recorded in treatment T11 75% RDF of N & P (75:37.5 kg/ha.) + 100% RDF of K (30 kg/ha.) + Azospirillum(2 kg/ha.) + Phosphobacteria (kg/ha.).

Investigations were carried out during 2014 and 2015 to study the effect of elevated CO2 and temperature on growth and yield contributing parameters of bell pepper (Capsicum annuum L.) under open top chamber (OTC) at research farm of Department of Environmental Science, Dr Y.S. Parmar UHF, Nauni, Solan, Himachal Pradesh with four treatments [T1(eCO2): OTC with elevated CO2 550±10 ppm; T2(eT & eCO2): elevated temperature by 1°C and elevated CO2 550±10 ppm; T3(aT & aCO2): ambient temperature and CO2 and T4: natural condition] and each treatment had two varieties (California Wonder and Solan Bharpur) of bell pepper which were replicated thrice. Results revealed that bell pepper recorded maximum plant height, leaf area, yield attributes under eCO2 which were significantly higher than all other treatments. However, the harvest duration and days to first harvest was lowest under eCO2. Higherfruit size as well as fruit weight was recorded with eCO2 followed by eT and eCO2, aT and aCO2 and open natural condition. But maximum number of fruits and highest fruit yield was obtained with natural condition which was significantly superior over eCO2 as well as over eT and eCO2 because increase in temperature negated fruit set due to less pollen viability under eCO2 and eT & eCO2 as compared to open. In open natural conditions due to higher pollen viability and more fruit setting as compared to higher CO2 andtemperature conditions, it resulted more yield. Solan Bharpur recorded higher total fruit yield (800.2 g plant-1) than California Wonder (399.1 g plant-1). Elevated CO2 has positive effect on plant growth and yield attributes in both cultivars of bell pepper. However, under interactive effect of elevated CO2 and elevated temperature, rising temperature negated the positive effects of elevated CO2 on crop production.
