To understand the effect of carbohydrate-based superabsorbent polymer (SAP) and crop-residue mulch (CRM) on pearl millet productivity and water-use efficiency (WUE), field experiments were undertaken for three consecutive years at 11 different locations (representing ⁓30 % of the global pearl millet growing area). Eight treatments, namely, Control; CRM 5.0 t/ha; SAP 2.5 kg/ha; SAP 5.0 kg/ha; SAP 7.5 kg/ha; SAP 2.5 kg/ha + CRM 5.0 t/ha; SAP 5.0 kg/ha + CRM 5.0 t/ha and SAP 7.5 kg/ha + CRM 5.0 t/ha were evaluated. Co-application of CRM and SAP increased pearl millet grain and stover yield by up to ⁓45 % and ⁓36 %, respectively. Pearl millet responded significantly up to 2.5 kg/ha SAP application (with or without CRM) only. Further, soil microbial biomass carbon improved significantly with CRM (20 %) and SAP (10.9–12.1 %) individually and with simultaneous application of CRM and SAP (⁓30 %). Likewise, dehydrogenase, alkaline phosphatase, acid phosphatase, and urease activities also improved significantly due to the co-use of CRM and SAP. Positive effects of CRM, SAP, and their co-application were also witnessed on soil microbial (bacterial, fungal, actinobacteria) populations and water-use efficiency (WUE) across environments. Among the locations, New Delhi and Aurangabad were the most desirable and stable ecologies, whereas Bikaner and Vijayapur remained the least consistent. Hence, to tackle the moisture-stress problem under pearl millet production systems and to achieve stable productivity, greater WUE and better soil microbial activity, CRM 5 t/ha in conjunction with SAP 2.5 kg/ha may be recommended across diverse ecologies.Not Availabl
खरीफ मक्का में शाकनाशियों द्वारा खरपतवार नियंत्रण : एक बेहतर विकल्प
No full textअध्ययन के नतीजे दर्शाते हैं कि खरपतवार प्रबंधन से मक्का में पौधों की ऊंचाई, शुष्क पदार्थ संचय और पत्ती क्षेत्र सूचकांक के साथ-साथ प्रति हेक्टेयर भुट्टों की संख्या, भुट्टे की लंबाई और प्रति
भुट्ट्टा दानों की संख्या जैसी उपज संबंधी लक्षणों में महत्वपूर्ण वृद्धि प्रदर्शित की। इसके अलावा, विभिन्न खरपतवार प्रबंधन प्रथाओं ने फसल की वृद्धि दर और सापेक्ष वृद्धि दर में उल्लेखनीय वृद्धि हुई। हालाँकि, इस अध्ययन में भुट्टा परिधि और 1000-दानों के वजन पर विभिन्न खरपतवार प्रबंधन विधियों का कोई महत्वपूर्ण प्रभाव नहीं देखा गया। अंकुरण के 15 दिनों बाद टेम्बोट्रियन (120 ग्राम / हेक्टेयर) या टोप्राज़ोन (25.2 ग्राम / हेक्टेयर) को अनुशंसित एट्राजनि (750 ग्राम / हेक्टेयर) की 75: खुराक के साथ मिलाकर टैंक मिश्रण अनुप्रयोग के परिणामस्वरूप उल्लेखनीय रूप से उच्चतम शुद्ध आय (₹56.19 हजार / हेक्टेयर), अतिरिक्त शुद्ध आय (₹53.09 हजार / हेक्टेयर), और शुद्ध आय लागत अनुपात (1.59) प्राप्त हुआ

No full textNot AvailableThe aim of study was to evaluate morphometric traits, growth and reproduction performance of indigenous Agonda
Goan pigs reared under coastal climate which supports livelihood development of resource poor farmers. Population
size in breeding tract varied depending on farmers’ preference for breeding and consumers’ demand for pork. Data
(n=74) on different parameters were recorded both from farmer’s flock and institute pig unit. Body measurements
such as body length, height at withers, chest girth and neck girth of both were measured using measuring tape. The
body weights at different ages i.e., birth, weaning and monthly interval up to one year of age were recorded using
digital weighing balance. The average body length, chest girth, height at withers and neck girth were 102.68±3.22 cm,
99.86±3.64 cm, 58.32±1.19 cm and 73.09±4.18 cm, respectively. The mean bristle yield (g/cutting), bristle length
(cm) and bristle diameter (micron) were 38.08±5.85, 4.45±0.04 and 268.21±9.84 in males, and 88.16±16.95,
5.69±0.07 and 270.93±11.07 in female pigs, respectively. The mean weight at birth was 0.59±0.01 kg and at weaning
was 3.76±0.12 kg. The yearling weights of adult male and female were 46.58±4.50 and 47.27±6.46 kg, respectively.
The average litter size at birth and at weaning was 7.21±0.41 and 5.93±0.28, respectively. Pre-weaning and postweaning growth rates were 79.25±9.86 and 153.85±13.34 g/day, respectively. This unique germplasm has potential
for sustainable production with improved pig breeding programs. However, the breed is under constant threat due to
indiscriminate crossbreeding with unbalanced admixture and replacement with exotic breeds for which immediate
conservation and improvement programs are essential to save the breed.Not Availabl

No full textNot AvailableMaize (Zea mays L.) is a significant cereal crop globally, ensuring food security in developing nations. It has become the third most important crop in India, known as the "queen of cereals" due to its adaptability to various growing conditions. Maize serves as human food, animal feed, and raw material for industries like food processing, poultry, dairy, and ethanol production. However, nutrient deficiencies pose a challenge, caused by imbalances in fertilizers, reduced transpiration, and unfavourable soil conditions. To address this, nutrient deficiencies must be identified early to achieve high yields and quality produce. Maize is an exhaustive crop that requires a balanced input of nutrients, as it depletes primary, secondary, and micronutrients from the soil. Soil fertility and expected outputs influence maize's nutritional needs, and external replenishment through organic and inorganic fertilizers is necessary. Current nutrient management practices often result in unbalanced plant nutrition, with micronutrient deficiencies such as copper, zinc, boron, and sulphur limiting maize yields. The routine use of NPK fertilizers across diverse soil types further exacerbates nutrient imbalances, impacting crop performance. Additionally, nutrient deficits in maize affect radiation use efficiency and leaf area index. Deregulated fertilizer prices have led to nutrient imbalances, decreased nutrient-use efficiency, and reduced farm profitability. Balancing the application of macronutrients (NPK) and ensuring an adequate supply of all 17 essential nutrients are crucial for optimizing crop performance.Not Availabl
