BREEDING COTTON GENOTYPES FOR HIGH DENSITY PLANTING SYSTEM – A NECESSITY IN THE INDIAN CONTEXT Pages: 1-10
- Seed Science
High Density Planting System (HDPS) in cotton is one of the alternate production system for enhancing productivity and is being followed in the major cotton growing countries viz., USA, Australia, China, Brazil and Uzbekistan by using compact plant varieties at a plant densities varying from 1.0 lakh to 2.5 lakh plants / ha. On the contrary India farmers are using robust hybrids due to which the plant population seldom exceeds 55,000 plants / ha which may be one of the reasons for low productivity i.e., around 500 kg / ha even after the introduction of Bt cotton hybrids. Cotton farmers in India are compelled to adopt HDPS even with Bt cotton hybrids involving high seed rate and cost. However, this practice is proved to be non remunerative as the architecture of the hybrid varieties does not allow any agronomic interventions

- Molecular Biology and Biotechnology
Rice (Oryza sativa L.) is one of the principal staple food crops, which feeds a major portion of the world’s population. Various biotic and abiotic stresses viz., plant diseases, pests, water scarcity, salinity, soil nutrient deficiencies and a rapidly changing climate affects the rice production significantly. In the present study, an effort was made to develop breeding lines in the genetic background of the elite, bacterial blight (BB) resistant, fine-grain type rice variety, Improved Samba Mahsuri (ISM) for tolerance to soil phosphorus (P) deficiency by using the rice line, Wazuhophek (possessing non-Pup1 type low soil P tolerance), as the donor.

- Plant Physiology
A field experiment was conducted during kharif 2015-16 and 2016-17 at College farm, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University, Hyderabad in strip-plot design with three replications to study the effect of moisture conservation practices (flat bed sowing, ridge and furrow, broad bed and furrow (BBF) and poly mulch on BBF) and integrated nutrient management treatments (Farmer’s practice, 100% RDF of 150:60:60 NPK kg ha-1, 125% RDF, 100% RDF along with 25% N through FYM or press mud) and their interaction effect on growth, yield attributes and productivity of Bt cotton.

- Agronomy
A field experiment was conducted during kharif 2017 and 2018 at ICAR-Indian Institute of Rice Research, Rajendranagar, Hyderabad to study the effect of different nitrogen management practices on the yield and yield attributes of rice under different establishment methods. The experiment was laid out in split plot design with two establishment methods [Normal transplanting (M1) and mechanized SRI (M2)] in main plots and six nitrogen management practices [N1- Nutrient Expert based recommendation of nitrogen with neem coated urea, N2- Nutrient Expert based recommendation of nitrogen with neem coated urea (75%) + vermicompost (25%), N3- Recommended dose of nitrogen with neem coated urea, N4- Recommended dose of nitrogen with neem coated urea (75%) + vermicompost (25%), N5- N omission, N6- Absolute control (No N, P and K fertilizer application)] in sub-plots with three replications.

- Agricultural Extension
An ex-post-facto research design was adopted to study the constraints faced by the Red gram farmers and the probable suggestions provided by them to overcome the constraints. Data were collected from 150 farmers. Weighted mean score (WMS) estimation of constraints showed that majority of the farmers faced problems with respect to labour shortage/ costly wages, lack of technical guidance about cultivation and untimely, costly and poor quality inputs. However, frequency estimations of suggestions represented a requirement of effective labour policies and the provision of subsidized inputs to overcome the above constraints.

- Agricultural Extension
To assess the effect of the training programmes organized by District Agricultural Advisory and Transfer of Technology Centre (DAATTC), Ongole, an investigation was carried out in Prakasam district of Andhra Pradesh during the year 2016-17. Training programmes organized for thirty paddy farmers and thirty two cotton farmers and the trainees of the training programme were the sample for the study purpose. The effectiveness of the training programme was assessed by studying knowledge levels of the farmers before and after participating in training programmes. Majority of the paddy farmers were in middle age group, with high school education, medium farming experience,

- Processing & Food Engineering
The increase in the trend of breakfast cereal and convenience food has raised the stage for several innovations to serve the need. Puffing is a very traditional and old practice of processing cereal grains that form light, fluffy, crispy product that are highly consumeracceptable. Puffed rice cakes are novel food products that have been recently added to breakfast cereals. There is accumulation of individually puffed grains to form a disc or biscuit like shape. The novelty of this product is that the disc shape is maintained by the grain without addition of any binding agents. Puffing is an instantaneous process which occur in few seconds at high temperatures to form light, fluffy expanded product that is crunchy and have good consumer acceptance.

- Apparel & Textiles
Azadirachta indica (commonly known as neem, nimtree and Indian lilac) belongs to the family Meliaceae. This tree is drought resistant and is native to the Indian subcontinent; it typically grows in tropical and semi-tropical regions. Its fruits, leaves and seeds have many medicinal and therapeutic values. In India, it is called as sacred tree and in villages serves as a pharmacy for many diseases. In the present study, natural dye was extracted from neem leaves through aqueous method which was used as colouring pigment in print paste for screen printing. Nanoparticles were prepared from neem leaves and these were mixed in the printing paste in different percentages to identify the difference in colour fastness and wash fastness along with colour improvement.

Rice is the most important cereal crop, which is the staple food for more than half of the world’s population. It has shaped the cultures, diets and economies of billions of people living in Asia where it has a long history of cultivation and is deeply ingrained in the daily lives of Asian people.

- Molecular Biology and Biotechnology
Rice is very important food crop for Asian countries. Among different biotic, abiotic stresses, drought is a major limiting factor for rice crop production. Plants are most susceptible to drought stress at the reproductive stage. Drastic grain yield reduction occurs if drought stress coincides with reproductive stage. So drought resistance at reproductive stage is very important trait (Yue et al 2006).The development of molecular techniques for genetic analysis has led to a great increase in our knowledge of cereal genetics and our understanding of the structure and behavior of cereal genomes. These molecular techniques, such as molecular markers, have been used to monitor DNA sequence variation in and among the species and create new sources of genetic variation by introducing new and favorable traits from land races and related grass species.
