Productivity and economics of hybrid maize as influenced by integrated nutrient management

ABSTRACT A field experiment was conducted to evaluate the integrated use of organic and inorganic source of nutrients on growth, yield and economics of hybrid maize during kharif and rabi seasons of 2008 and 2009 at the irrigated upland farm of Tamil Nadu Agricultural University, Coimbatore. The experiment was laid out in randomized block design with three replications and ten treatments. The results revealed that significant increase in growth parameters, yield components, grain and stover yield of hybrid maize were recorded with the application of 50 per cent RDF through poultry manure + 50 per cent RDF through inorganic fertilizers followed by 50 per cent RDF through vermicompost + 50 per cent RDF through inorganic fertilizers. The net income was highest with 100 per cent RDF through inorganics during 2008, while in 2009, 50 per cent RDF through poultry manure in combination with 50 per cent RDF through inorganic fertilizers treatment recorded higher values. The B:C ratio was higher with 100 per cent RDF through inorganics during both the years

Soil Fertility and Yield of Finger Millet (Eleusine coracana L.) as Influenced by Phosphorus Management Practices in Sandy Loam Soils

Finger millet (Eleusine coracana L.) is an important small millet crop grown in India and has the pride of place in having highest productivity among millets. However, the productivity comes down in low available soil phosphorus areas where finger millet is grown. A field experiment was carried out at Agricultural Research Station, Perumalapalle, Tirupati, Acharya N. G. Ranga Agricultural University, Andhra Pradesh, India during kharif, 2018 on sandy loam soil to study the effect of phosphorus fertilizer, PSB and VAM on soil fertility status and yield of finger millet. The experiment was laid out in randomized block design with nine treatments consists of combination of phosphorus fertilizer, PSB and VAM and replicated thrice. Soil samples were collected at initial and after harvest and analyzed for physico-chemical, chemical properties and grain yield was recorded after harvest. The results revealed that application of PSB, VAM along with phosphorus fertilizer exerted significant effect on available N, P2O5, K2O, S and DTPA extractable micronutrients. Significantly  the highest  available N (150 kg ha-1), P2O5 (42.34 kg ha-1 ),  K2O (227 kg ha-1 ), S (9.57 mg kg-1 ),  DTPA extractable Manganese (38.67 mg kg-1) was registered with application of 100 %  RDP + PSB @ 750 ml ha-1 + VAM @ 12.5 kg ha-1 (T6). Moreover, this treatment led to the highest recorded grain yield of finger millet, achieving 4328 kg ha-1. Physico-chemical properties (pH, EC and OC) was non significant with phosphorus management practices. In conclusion, the results underscore the positive impact of the combined application of PSB, VAM, and phosphorus fertilizer on both soil fertility parameters and finger millet yield. This research provides valuable insights for enhancing agricultural practices in regions characterized by sandy loam soils and low phosphorus availability, contributing to the sustainable productivity of finger millet crops in India

Nutrient Content, Uptake and Yield of Finger Millet (Eleusine coracana l.) Influenced by Phosphorus Management Practices

The experiment was carried out at Agricultural Research Station, Perumalapalle, Tirupati, Acharya N. G. Ranga Agricultural University during kharif season of 2018 on sandy loam soil to study the response phosphorus fertilizer, PSB and VAM on yield and nutrient content and uptake of fingermillet. The experiment used a Randomized Block design with nine treatments and was reproduced three times. Among the phosphorus management practices, application of RDF + PSB @ 750 ml ha-1 + VAM@ 12.5 kg ha-1 (T9) showed its best results with respect to nutrient content and uptake at flowering and harvesting stage as compared to other treatments

Constraints Encountered by Rural Youth for Establishment of Agri-Enterprises and Elicit Suggestions to Overcome Them

India is with a high level of youth unemployment. Markets have insufficient jobs to absorb young job seekers. The purpose of the study was to identify constraints and suggestions that are faced by the rural youth who are engaged in agri-enterprises. A sample of 240 youth involved in agripreneurshipwasgiven questionnaires. The findings of the study indicated that the youth faced many challenges while establishing their agri-enterprises.The primary constraint faced by rural youth were economic constraints followed by technical constraints, psychological constraints, extension-related constraints, social constraints,and other constraints. The constraints perceived and the suggestions given by the rural youth for the establishment of agri-enterprises to overcome their constraints were observed and depicted

Yield and Nutrient Uptake of Pigeonpea [Cajanus cajan (L.)] as Influenced by Tillage, Nutrient Levels and Foliar Sprays

A field investigation was conducted during two consecutive kharif seasons of 2019-20 and 2020-21 to study the effect of tillage, nutrient levels and foliar sprays on yield and nutrient uptake of redgram on sandy loam soil which was low in available nitrogen, medium in available phosphorus and available potassium. The research was conducted in a split-split plot design, consisting of three tillage practices in main plots, three nutrient levels in sub-plots and three foliar sprays in sub-sub plots. Higher seed yield and nutrient uptake of redgram was recorded with vertical tillage with subsoiler upto 60 cm deep at 1 m interval with application of 125 % RDF and with foliar application of KNO3 1 % twice with 15 days interval at 50 per cent  flowering stage

Training Needs of Rural Youth towards Agri-Enterprises

The study is an attempt to understand training needs in areas of agrienterprises. Investigation was carried out in three regions of Andhra Pradesh. Exploratory research design was used. The respondents (n=240) were the youth residing in the villages at the time of investigation. Simple random sampling technique was used for sample collection from twenty four villages. Pre-tested interview schedule was used for data collection. The inferential statistical tools like mean, standard deviation, frequency, percentage were used for analysis of data. An attempt was made to assess the areas of training needs to be focused mainly for agripreneurs to run their agri-enterprises smoothly. Manufacturing techniques (2.69) ranked first among the list of areas training needs for agripreneurs
