Science Must Guide Policy on Protein Hydrolysate Biostimulants
No full textIndia’s commitment to sustainable agriculture has historically been anchored on the balance between tradition and science. Recent advances in plant biostimulants, the substances that enhance plant growth, nutrient use efficiency, and resilience to stress have offered promising tools for improving crop productivity under climate challenges. Among these, protein hydrolysate (PH) -based biostimulants have emerged as one of the most significant innovations, providing an environmentally acceptable alternative to regular fertilisers. However, a recent policy reversal removed animal-origin protein hydrolysates from the Fertiliser (Control) Order (FCO), 1985. This decision risked the years of scienceled agricultural reforms like the plant biostimulants, critical in boosting low productivity in the face of climate change. The decision, which was made public on 29 September 2025, through Gazette Notification S.O. 4441 (E) removed all the eleven approved formulations of protein hydrolysates of animal origin from Schedule VI, banning their use as biostimulants
Energy Transition for Atmanirbhar Bharat
No full textIn the 21st century, agriculture stands at the crossroads of transformation— driven not just by the need for higher productivity but by the urgency to make farming sustainable, low-carbon, and energy-efficient. The confluence of renewable energy and agriculture is now emerging as the next big paradigm shift for rural Bharat, promising to reshape the way we cultivate, process, and sustain our natural resources. For a long time, agriculture has been seen as a passive consumer of energy— dependent on fossil fuels for irrigation, mechanization, fertilizers, and logistics. Today, it is rapidly evolving into a producer of clean energy and a steward of the planet’s carbon balance. Renewable energy technologies— especially biomass-based solutions— are proving that the farm can not only feed the world but also power it sustainably

Effects of Blanching Parameters and Partial Drying on the Physicochemical Properties of Sweet Potato Slices
No full textThis study assesses the effects of temperature and time in hot water blanching on physical and biochemical properties of sweet potato slices. It also aimed to identify suitable blanching conditions followed by partial drying at 90°C to reduce moisture content for producing semi-perishable sweet potato slices. Sweet potato slices were blanched at various temperatures from 80°C to 100°C for 60 to 300 seconds durations. The results showed that the most favourable blanching settings was 100°C for 300 seconds, whichresulted in the maximum total sugar and ascorbic acid content retention, as well as the best sensory properties. The chemical parameters on selected blanching settings of 100°C for 300 seconds were as 16.56±0.5 mg 100g-1 ascorbic acid, 17.59±0.78% total sugar, and 5.6±0.0 pH. It was observed that it took 300 min to reach the moisture content of 30% on wet basis with an average drying rate of 6.3 g water g-1 of dry matter min-1. This study provides a scientific basis for selecting appropriate blanching and partial dryingconditions to produce semi-perishable sweet potato slices with improved nutritional retention, sensory quality, and shelf-life
Trends in the Growth and Development in the Cotton Sector
No full textTrends in Fibre Production and Trade The historical trend of India’s cotton production demonstrates remarkable growth, rising from approximately 33.4 lakh bales in 1950-51 to over 320 lakh bales in 2023-24. This increase is attributed to advancements in farming techniques, the adoption of hybrid seeds, and supportive government policies. The most significant growth occurred after the year 2000, following the introduction of Bt cotton. Similarly, productivity has also increased, surpassing 500 kg/ha in the last decade, with a decadal average of around 440 kg/ ha. However, production trends have fluctuated in the last decade, which can be attributed to climate change, pest resurgence in Bt hybrids, and the emergence of sucking pests. These trends highlight the need for new technological interventions, climateresilient cotton varieties, and improved agronomic practices to sustain high productivity. Increasing attention is being paid to the mechanization of cotton cultivation, including harvesting, to reduce dependence on human labour-which accounts for around 25% of cultivation costs-and to minimize contamination, which is crucial for the value chain industries
Assessment of Evapotranspiration, Water Productivity and Yield Response Factor for Groundnut under Deficit Irrigation Using Lysimeter in a Hot Arid Ecosystem
No full textIn this study, we focused on precise determination of actual crop evapotranspiration (ETc) of groundnut in an arid region of India using single load cell-based mini-lysimeters. This study, for the first time, integrated two water saving techniques, i.e., pressurized irrigation system through mini-sprinklers and deficit irrigation strategy. The groundnut crop (var. Girnar-2) was grown in lysimeter as well as in field plots under deficit irrigation treatments based on cumulative pan evaporation (CPE), i.e., T1 (100% of CPE), T2 (80% of CPE), T3 (60% of CPE) and T4 (40% of CPE) with three replications during 2014-2018. Lysimeters’ weights were monitored daily to determine ETc and soil moisture at weekly interval. Yield response factor (Ky) and crop water productivity were computed in all four treatments. The ETc (661-817 mm) and pod yield (4.2 t ha-1) for groundnut were obtained as the highest in treatment T1. However, water productivity was maximum (0.61 kg m-3) in treatment T2 on sacrificing 8.7% of the yield obtained in treatment T1. The mean Ky value for groundnut under deficit irrigation was computed as 0.63 and varied from 0.68 (T2) to 1.34 (T4). This finding indicates that groundnut can tolerate up to 80% deficit irrigation, and beyond this level, the crop becomes sensitive to water stress with large reduction in pod yield. On the other hand, the pod yield revealed 24% and 46% reductions at 60% and 40% deficit irrigation levels, respectively. Therefore, in arid climate, where water is a precious and limited natural resource, irrigation at 80% CPE in groundnut crop is plausible and profitable irrigation water management strategy
हिमालय में भूमि क्षरण: चुनौतियाँ और संरक्षण रणनीतियाँ
No full textभारत के हिमालय में वन क्षेत्रों में भूमि क्षरण एक गंभीर समस्या है। इस क्षेत्र में 40 प्रतिशत छत्र वाले खुले वनों के अंतर्गत क्षेत्रफल (कुल भौगोलिक क्षेत्र, टीजीए का 3.06 प्रतिशत) राष्ट्रीय औसत (टीजीए का 2.52 प्रति शत) से अधिक है। डेटा विश्लेषण से पता चला है कि उत्तर पश्चिमी हिमालय (एनडब्ल्यू एच) की तुलना में उत्तर पूर्वी हिमालय (एनईएच) में खुले वनों के कारण भूमि क्षरण लगभग छह गुना अधिक गंभीर है। एनईएच में स्थानांतरित खेती और अंधाधुंध वनों की कटाई अधिक प्रचलित है। जबकि देश भर में केवल 1.79 प्रति शत टीजीए बंजर और पथरीली बंजर भूमि से प्रभावित है, यह आंकड़ा हि मालयी क्षेत्र में 6.69 प्रतिशत तक बढ़ जाता है। पथरीली बंजर भूमि का क्षरण विशेष रूप से एनडब्ल्यू एच में गंभीर है, जि समें 11.55 प्रति शत टीजीए प्रभावित है, जो (एनईएच टीजीए का 1.02 प्रति शत) की तुलना में लगभग 11 गुना अधिक है
