Soil test crop response experiments on rice were conducted in Bastar plateau Agro-Climatic Zone of Chhattisgarh during 2009-2011 to assess yield, soil, plant and fertilizer nitrogen, phosphorus and potassium (NPK) nutrient relationships and calibrate optimum fertilizer doses for attaining yield targets. Soil fertility status was low to medium for N (194-283 kg ha -1 ) and P (7.53-19.66 kg ha -1 ), and medium to high for K (226-320 kg ha -1 ). Based on nutrient requirement (NR, kg q -1 ), contribution from soil [CS, %], fertilizer [CF, %] and farm yard manure [CFYM, %], optimum fertilizer doses were derived. The fertilizer doses were validated for attaining yield targets of 5000 and 6000 kgha -1 in farmer's fields. Rice yield within 10% deviation was attained, which indicated that soil test based fertilizer dose was superior. This A c c e p t e d M a n u s c r i p t 2 approach could be adopted for regions with similar soil and agro-climatic conditions in other parts of the world to increase rice yields.
Field Study on Nutrient uptake and Physico – chemical properties of soil influenced by organic and inorganic packages in rice was carried out at Research Cum Instructional Farm IGKV., Raipur (C.G.) during kharif 2010 and 2011. The soil of experimental field was ‘Inceptisols’ (Matasi), which was low in nitrogen, medium in available phosphorus and potassium. The experiment was laid out in randomized block design with three replication. The treatments consisted of Basmati type rice variety viz. Kasturi Comprising organic, inorganic and integrated nutrient management. Treatment T1 (50% RDF + 50% N (CDM), T2 (100% N((1/3 rd each CDM +NC+CCR) T3 (100% N (1/3 rd each CDM + NC + CCR) + Green manure in rice), T4 100% N (1/3 rd each CDM + NC + CCR) +Deep summer ploughing), T5 (50% N(CDM)+RP+PSB+Azos.), T6 (100%N(1/3 rd each CDM+NC+CCR) + Azos.+ PSB) and T7 (100% RDF).among different nutrient management practiceshigher nutrient uptake in grain and straw were observed under treatment T7(100% RDF).followed by T1 (50% RDF + 50% N (CDM) an INM treatment.whereas water uptake was exceeding in100% N applied through 1/3 rd each CDM + NC + CCR + Green manure in rice. Bulk density, pH and EC were also exceeds in T7, except T6 (100% N CDM + NC + CCR + Azos + PSB) which has higher OC.
The present study was carried out to evaluate the performance of strawberry cultivars in mid hill region of Kullu valley of Himachal Pradesh. For this purpose nine strawberry cultivars viz Addie, Belrubi, Brighton, Chandler, Dana, Etna, Fern, Pajaro and Selva were planted at spacing of 30 x 15 cm in double rows on raised beds of 1m × 3m size at Regional Horticultural Research and Training Station, Bajaura, Kullu, Himachal Pradesh. The experiment was laid out in a Randomized block design. The maximum plant height (16.37cm) was recorded with cv. Belrubi and maximum plant spread was attained by cv. Fern (EW 23.27 cm and NS 21.03 cm), maximum leaf length (16.90 cm) was recorded by cv. Belrubi and minimum (10.00 cm) with cv. Dana. The maximum leaf area was recorded with Chandler (76.03 cm2). The maximum fruit weight (14.93gm), total soluble solids (12.00oB), reducing sugars (5.01%) and total sugars (5.44%) were recorded with cv. Chandler. The maximum fruit yield per plant was observed with cv. Belrubi (996.3g/plant) which was closely followed by cv. Chandler (966.7 g/plant). Thus from the above studies it is concluded that Strawberry cultivars Belrubi and Chandler were best for commercial cultivation in mid hill region of Kullu valley of Himachal Pradesh.
The study was undertaken to evaluate the performance of some spur and coloured strains of apple (Malus domestica Borkh.) under low altitude conditions of Kullu valley of Himachal Pradesh. The commercial cultivar Starking delicious introduced in the beginning of the century now does not develop good colour and shape at lower altitude and warmer areas of Himachal Pradesh, due to climate change therefore, two spur cultivars Red Spur and Starkrimsom, four coloured strains Top Red, Vance Delicious, Hardeman and Skyline Supreme Delicious and two spur type pollinizers Stark Spur and Gold Spur grafted on M9 rootstock were compared with commercial cultivar Starking delicious grafted on M9 rootstock at a warmer location Bajaura, Kullu located at an altitude of 1090 m above MSL. The cultivars Vance delicious and Red Spur developed good colour and fruit shape and ripened 11 and 9 days earlier than Starking delicious. Top Red resulted in the highest trunk girth (27.0 cm), shoot growth (17.7 cm) and yield (58.63 t ha -1 ) for the last five years followed by Vance delicious with trunk girth 26.2 cm , shoot growth 16.1 cm and yield 53.64 t ha -1 ). It ripened four days earlier to Starking delicious. Other cultivars ripened simultaneously or later than Starking delicious. Vance delicious appeared to be the most suitable cultivar for lower altitude and marginal areas of Himachal Pradesh and has been recommended for commercial cultivation as it performed well under seasonal variation in temperature and rainfall that occurred during the study period.
