Abstract
To find out the effect of cuttings and foliar application of nutrients on growth, yield and seed quality of spinach beet, a field experiment entitled “Effect of Cuttings and Foliar Application of Macro and Micro Nutrients on Growth and Seed Yield in Spinach Beet (Beta vulgaris var. bengalensis)”was conducted at Vegetable Experimental Farm-I, Division of Vegetable Science and Floriculture,Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, during second fortnight of October 2020-21.The experiment was replicated thrice in RBD (Factorial) consisting of 02 factors viz., cutting frequencies with four levels i.e., C0, C1, C2& C3 andfoliar application of macro and micro nutrients at five levels ( A0, A1, A2, A3& A4) respectively.
The results on growth, yield and quality parameters revealed that among different treatments maximum height was observed in C0 (no cutting)(36.18cm),(60.08cm)and (225.25 cm),while minimum height was observed in the treatment with three cuttings (25.64cm), (25.99cm) and (178.53cm). Among macro and micronutrients application more height was observed in treatment A4 (23.04 cm), (31.98 cm), (41.77 cm) and (208.00 cm). More green leaf yield kg per plot (18.80)was recorded in treatment C3(three cuts). Among the macro and micro nutrients more yield was recorded in treatment A4(12.69 kg). However,lesser green leaf yield (9.25 kg/plot) was recorded in treatment A0. Among the interaction studies more yield (21.64 kg) was recorded in C3A4and lesser in treatment combination of C1A0 (7.77 kg). More green leaf yield (220.01q/ha) was recorded in C3 and minimum yield (105.86 q/ha) was recorded in C1.Among the macro and micro nutrients treatment A4 recorded the higher green leaf yield (141.04 q/ha) which remain at par with A3. Significantly lower leaf yield per hectare (86.36q) was recorded in treatment combination C1A0.Considering the intervals between successive cuttings, treatment C1 significantly took a maximum number of days (45.93) whereas minimum number of days was recorded after second cutting. Treatment A4 with foliar application recorded minimum number of days (51.16). Among interaction studies, maximum number of days was recorded in treatment combination of C1A0.Significantly lesser number of days (102.73) to 50% flowering was recorded in treatment C0 and maximum number of days to 50% flowering was recorded in C3 treatment. Among macro and micronutrients application more number of days to 50% flowering (127.66) was recorded in treatment A4 which remained at par with A3. Maximum seed yield per plant was observed in C1 (23.22 g) which remained at par with the control. Foliar treatment A4 (RDF+15ppm micro nutrients+100 ppm macronutrients) recorded the maximum seed yield (23.94 g). Among interaction studies, more seed yield was recorded in C1A4 (27.47g).Similarly more seed yield per plot and per hectare was recorded in C1 and lesser in C3. Same treatment (C1) recorded maximum germination (81.73 %). Among macro and micro nutrients application maximum germination (80.83 %) was recorded in A4 (RDF+15 ppm micronutrients+100 ppm macronutrients). Also more seedling vigour index (1365.01) was recorded in same treatment (C1). More seedling vigour index (1390.00) was recorded in foliar treatment A4. A perusal of the interaction studies shows thatmore seedling vigour index (1573.36) was recorded in C1A4 (One cutting+RDF+15 ppm micronutrient+100 ppm macronutrient). Considering the economic aspects of the studies conducted it was evident that treatment combination C1A4 gave maximum B:C ratio (1:4.30) followed by C2A4 (1:3.90) whereas the control treatment combination yielded minimum B:C ratio (1:1.06).
