Maize shelling is one of the tedious and time-consuming agricultural operations. To reduce the drudgery of farm women involved in maize shelling, a hand-held octagonal maize sheller (OMS) tool was introduced. The OMS tool was evaluated for its impact on human health and shelling efficiency. An ergonomic study of the OMS tool was carried out with farm women as subjects for evaluation. Various ergonomic and technical performance parameters were assessed for two types of shelling viz. hand shelling and shelling using OMS tool. The results revealed that the OMS tool and hand shelling recorded an output of 23.71 and 8.87 kg/h, respectively. The cardiac cost per unit of output worked out was 69.73 and 287.09 beats/kg for OMS tool and hand shelling, respectively. Compared to hand shelling, the OMS tool reduced drudgery by 75.71%. Overall discomfort rating was 1.58 and 2.12 while the body part discomfort score was 21.27 and 30.41 for OMS tool and hand shelling, respectively. Adoption of OMS tool reduced the physical stress as very small percentage of subjects (less than 40%) reported about the body pain. In view of increased shelling efficiency and reduced physical pain, the OMS tool was found more suitable and is recommended for maize shelling.

ICAR-CISH has developed four mobile apps on mango products, two on guava products and two on aonla products to disseminate value addition protocols of respective fruits. In this work, mobile apps have been developed to provide advisory on preparing quality processed products of main fruits of Subtropical region. For developing apps, cloud- based tool viz. ‘’MIT app Inventor2.0’’ was used. This tool can be used for app development using visual, event-based block programming method in browser itself. The apps were developed to provide advisories on preparation of quality processed fruit products such as different types of pickles, squash, murabba, candy, RTS drinks, etc. Apps provide audio facility as well as calculation of ingredients amount on a mouse click. These apps are very interactive and helpful to the farmers in preparing quality processed products of fruits even at cottage scale. These apps are available on ‘Google Play’ for free download. The information provided by app will be helpful in reducing post harvest losses of fruits, generation of employment opportunities and improve the livelihood status of the farmers.

Pigeonpea [Cajanus cajan (L.) Millsp.] is a favourite crop of rain-fed farmers due to its high food value, drought tolerance and various soil improving properties. The productivity enhancement of this crop has been a long-term goal at the national level but with a little success. In this context, the advent of hybrid breeding technology with over 30% on-farm yield advantages has provided a much-needed breakthrough. The hybrids in pigeonpea were bred using a stable CMS system and natural out-crossing. It is believed that the adoption of locally adapted hybrids would contribute significantly towards both family income and nutrition.

A field experiment was conducted during Rabi 2015-16 and 2016-17 at ICAR-Central Potato Research Station, Patna Bihar. In this experiment F1 with initial clonal generations viz F1C1, F1C2 and F1C3 were evaluated. The screening and selection of these generations were done in randomized block design for the character like early bulking, tuber size, tuber shape, depth of eye, tuber colour and resistance to late blight of potato etc. A total of 12,360 True Potato Seeds of 17 successful crosses and 7,322 True Potato Seeds of 23 successful crosses were sown and seedlings were transplanted, out of these 610 and 187 clones were selected during 2015-16 and 2016-17 respectively. Large number of potato cultures were planted for further evaluation in next generations. In F1C3 the cultures were planted along with more than six check varieties of potato. Cultures were evaluated and selected considering total tuber yield, shape, colour and disease reactions for further evaluation in PYT.

India is currently trying hard to get a status of $5.0 trillion economy. Agriculture contributes $400 billion to the Indian economy, which is 2nd after China. To achieve this mammoth national target, allsectors of economy viz., agriculture, industry and service have to outperform outstanding. To achieve this target, our total export should be of $1.0 trillion annually and share of agriculture and the allied sector should be 10 %.To achieve $100 million agri-export, smart agriculture is pivotal to sustain our products at international level. Agritech startup can play a vital role in this endeavour; however, the bottleneck should be removedwithin the least possible time. If we succeed in this endeavour, this will not only lead to enhance per capita income from the current $1800 to $3600 but also double the income from farming systematically. Unfortunately, due to worldwide attack of global pandemic of Covid- 2019 disease, every sphere of life has been severely paralysed. Agriculture sector was less affected as the food grain output was recorded highest ever (295.67MT) and sector growth 3.7 % in absolute term and 11.3% on the current price, during 2019-20. India will get rid off of such disasters relativelyfaster as compared to other nations, but this has the potential to push forward our economic dream to beam reality atleast for a year or so.Probably India would be able to achieve the tag of $5.0 trillion economy not sooner than 2026-27.

The standing crop biomass in different plant compartments was found to be variable with the age of the crop. The total plant biomass of ageing plant indicated a sigmoidal curve in three varieties of Birsa Kulthi–1, Birsa Kulthi–2 and Birsa Kulthi–3. The total plant biomass was recorded to be 115.53 g/m2 (Birsa Kulthi–1), 92.85 g/m2 (Birsa Kulthi–2) and 72.42 g/m2 (Birsa Kulthi–3) at final harvest i.e. 105 days. Contribution of stem and leaves to the total plant biomass has increased between 15 and 90 days. Infl./pod biomass per cent as found to be increasing throughout. Standing dead biomass was maximum 9.40 per cent (Birsa Kulthi–1), 8.97 per cent (Birsa Kulthi–2) and 6.53 per cent (Birsa Kulthi–3) at final harvest i.e. 105 days. Peak values for current increments in biomass were observed at 90 days in Birsa Kulthi–1 and 105 days in Birsa Kulthi–2 and Birsa Kulthi–3. The peak values for net primary productivity were found to be highest at 90 days for Birsa Kulthi–1 and 105 days harvest for Birsa Kulthi–2 and Birsa Kulthi–3.

A field experiment was conducted during four consecutive winter seasons from 2013-14 to 2016-17 at Patna, Bihar under sandy clay loam soil. The trial on potato was laid out in randomized block design with four replications with objective to develop nutrient omission plot technique in potato. The highest plant height and number of shoot per plant were recorded under 150% recommended dose of fertilizer of NPK. The range of dry matter content in potato tuber varied from 16.1 to 17.7% on dry weight basis. The maximum yield of smallest tuber (0-25g) was recorded under 150% recommended dose of fertilizer of NPK, which was at par to all the nutritional treatments and significantly superior over absolute control plot. The maximum yield of medium, large and very large size tuber was recorded under 150% recommended dose of fertilizer of NPK. However, 150% recommended dose of fertilizers of NPK recorded about 13% higher net return over 100% recommended dose of fertilizers of NPK. The maximum yield reduction was observed in the omitted plot without nitrogen among other nutrients like phosphorus and potassium. Hence, nitrogen was one of the most limiting nutrients for tuber yield of potato.

A study was carried out in an attempt to obtain simple and efficient soil test method(s) for determination of available nitrogen (N), phosphorus (P) and potassium (K) in Mollisols. Soil samples were collected before sowing of direct-seeded rice (DSR) and wheat in sequence to evaluate the soil test methods for available N, P and K. Methods used were wet-oxidation for organic carbon (OC); alkaline KMnO4 for available N; Olsen’s-P, AB-DTPA and Mehlich-I for available P; and NH4OAc-K, AB-DTPA and Mehlich-I for available K. Suitability of these methods for given soil nutrients was evaluated by comparing the R2 values (coefficient of determination) obtained from regression analysis. Results showed that the R2 values of obtained equations by using different combinations of soil test methods for the determination of available N, P and K in soil were highly significant in both the crops. Highest R2 value for DSR (0.442**) and wheat (0.898**) were observed with the combination of OC, Olsen’s-P, ABDTPA-K, and OC, Olsen’s-P, Mehlich-K, respectively. It showed that these combinations are more promising and superior over other methods.

Kerala is the leading producer of Black Pepper, king of spices in India. The harvesting of pepper is of great concern to the farmers. The shortage of labour during harvesting and their high wages causes a burden to pepper farmers. The delay in harvest reduces quality. The machine developed was expected to bridge the gap between supply and demand of pepper. The machine consists of a motor, mainframe, harvesting and conveying unit and collecting bag. Initial testing of the developed model was conducted under field condition. The tests revealed that the developed model was successful and effective for harvesting pepper due to its better conveying mechanism towards the collecting bag. With few modifications, the harvester could be made available for commercial production.
